The material consists of a thin polyimide film, that is resistant to chemical degradation from electrons.</b></p>​<span style="background-color:initial">In a collaboration project with ABB Sweden and DuPont, researchers at Chalmers University of Technology have evaluated new materials for motor insulation exposed for modern power electronics inverters, especially for electromobility applications. </span><div><br /></div> <div>The study evaluated the impact on the insulation material of increased electrical stresses caused by high switching frequency converters with a faster rise of voltage with respect to time on the conductor insulation materials used in today’s advanced traction motors. These converters are usually silicon carbide-based and can be found in modern electric vehicles. In the tests the conductor insulation was also exposed to high temperatures (150 to 180°C) and high voltages (3.0 and 3.5 kV). </div> <div><br /></div> <div><strong>New material provides an eight-fold improvement</strong></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Nytt%20isoleringsmaterial%20gör%20elbilsmotorer%20tillförlitligare/Shafigh-Nategh_200px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:170px;height:213px" />“We concluded that Kapton ECRC polyimide films may be considered as proper candidates for traction motors supplied by high-switching frequency converters designed and produced for the electrification market,” says Shafigh Nategh, research project leader at ABB and adjunct associate professor at the department of Electrical Engineering at Chalmers. “The comparison between non-corona resistant Kapton FN and the 25 percent thinner corona resistant Kapton ECRC materials showed that Kapton ECRC film increased the average life-time of the insulation by about eight times.”</div> <div><br /></div> <div>“The research findings help DuPont better understand the impact of increased switching frequency from inverters on a new generation of corona-resistant Kapton polyimide film wire insulation,” says Shawn Filliben, technical service senior consultant for DuPont Kapton films. “This new technology will enable designers to have higher performing thin insulation to compete with historical enamel solutions. A thinner insulation material will also provide an additional degree of design freedom for those looking to create smaller, more reliable motors.”  </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Nytt%20isoleringsmaterial%20gör%20elbilsmotorer%20tillförlitligare/Yujing_Liu-3_200px.jpg" alt="Yujing Liu" class="chalmersPosition-FloatRight" style="margin:5px;width:170px;height:226px" />“Chalmers has a strong background in electric power engineering, and we are involved in exploring new technologies for electromobility applications together with several well-known industrial partners,” says Yujing Liu, professor and head of the unit Electrical Machines and Power Electronics at Chalmers. ”This is an excellent show-case project for collaboration between industry and academia.”</div> <div><br /></div> <div><strong>Three complementary roles </strong></div> <div>With strong background in motor manufacturing, ABB formulated the new challenges in electrical machines for future vehicles and verified the new solutions against the targeted applications. DuPont, one of the world’s largest insulation material producers, provided the newest materials to deal with challenges. Chalmers, with strong electronics hardware competence and good lab facilities, developed advanced testing set-up and conducted time-consuming sample tests.</div> <div><br /></div> <div>“We are very proud that Chalmers could contribute to this evaluation of the break-through insulation technology with world-leading companies.

But how do we get there? With her research about this, Sigma Dolins was awarded third prize in the EARPA Young Researchers Pitch Competition.</b></p>​<span style="background-color:initial">Sigma Dolins is a doctoral student associated to Chalmers University of Technology, Keolis and RISE, Research Institutes of Sweden. In her work, she is looking into cultural and societal factors that may facilitate – or hinder – the development towards shared transportation.<br /></span><div><div>“New forms of mobility, like electric and autonomous vehicles, can merge with ride sharing to an evolved form of transportation. One day electric, autonomous, connected, on-demand vehicles can take us to a magical place; transportation heaven!”, she says.</div> <h2 class="chalmersElement-H2"><img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_bilder-utan-fast-format/Sigma-Dolins_300.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><span style="font-family:inherit;background-color:initial">Best of all: social cohesion</span><br /></h2></div> <div>In “transportation heaven”, there are less emissions, fewer accidents and less vehicles on the roads. We can book any type of vehicle from one single app, and spend less time and money on travel. But to Sigma Dolins, the best goal of all is perhaps social cohesion.</div> <div>“If everyone had access to good, safe transportation, if owning a car wasn’t a reflection of personal wealth or identity… if we shared ten-fifteen minute journeys with people who don’t look exactly like us, but still live in our neighborhood… I think that would create interesting and beneficial changes to society”, she says.</div> <div>But it is not an easy shift to make.</div> <div><div>“We cannot talk about autonomous vehicles as a desirable consumer product, instead we need to understand how to redefine for people what public transport is and could be. That means changing how we, as a society, interact with mobility.”</div> <h2 class="chalmersElement-H2">Cultural factors affect willingness to share</h2></div> <div><div>Sigma Dolins is now, together with a colleague at the Aristotle University of Thessaloniki, looking at shared autonomous vehicles as a socio-technical system. They are working on a multinational, longitudinal study that focuses on cultural factors that affect our willingness to share. The aim is to create an index for understanding societal attitudes towards mobility, sharing and autonomous vehicles. The index will be both descriptive and prescriptive; what policies, services or measures are needed to change attitudes?</div> <h2 class="chalmersElement-H2">Fear of strangers a hinder</h2></div> <div>The main obstacle when trying to get people to share rides is, in the opinion of Sigma Dolins, that people are actually afraid of each other.</div> <div>“Right now, we don’t have a culture of how to behave inside a small space with strangers. The closest approximation is an elevator – usually people are totally silent and the ride lasts less than a minute. Price is the easiest and right now most effective way to get people to try sharing. I think a combination of price and ubiquity will be key to success”, she says, and continues:</div> <div><div>“My early thoughts are that culture definitely influences perceptions of privacy and public space. Asian countries tend to think differently about privacy, and so crowded public areas – pre Covid-19 – were considered very normal. Sharing with strangers was done out of necessity and thus normalized. But these also tended to be families and households that didn’t grow up with a private car. Part of my investigation is to see how many people grew up with a family car and how much that ingrains these behaviours later in life.”</div> <h2 class="chalmersElement-H2">Important to communicate</h2></div> <div>The EARPA Young Researchers Competition was a way of getting exposure to industry, but more than anything it was an opportunity to get feedback and sharpen the presentation technique, Sigma Dolins explains.</div> <div>“I think it’s important for more PhD students to get these kinds of opportunities. The “butterflies in stomach” feeling is awful, so I know why a lot of students avoid it. But communicating our science is 49% of the battle of doing the science!”<br /><br />Text: Mia Malmstedt<br />Photo: iStock and Birger Löfgren, RISE</div> <div><br /></div> Wed, 28 Oct 2020 16:00:00 +0100https://www.chalmers.se/en/departments/e2/news/Pages/A-technology-that-alerts-if-you-doze-at-the-wheel.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/A-technology-that-alerts-if-you-doze-at-the-wheel.aspxA technology that alerts if you doze at the wheel<p><b>​Researchers at Chalmers and Autoliv are developing an IT platform that, in the vehicle setting, recognises the signs of a driver getting sleepy. In the beginning of next year, the system will be tested by 50 drivers on public roads in Gothenburg.​</b></p>​<span style="background-color:initial">“Sleepiness is the cause of many traffic accidents, and by using new technology we can help drivers to refrain from driving when they are not completely alert”, says Stefan Candefjord, Assistant Professor at the Department of Electrical Engineering, Chalmers University of Technology.</span><div><br /><span style="background-color:initial"></span><div>The aim is to measure, analyse and communicate physiological signals in a vehicle. The project is called COPE, Connected Occupant Physiological Evaluation, and is run jointly by researchers from Chalmers and Autoliv.</div> <div><br /></div> <div>When a person becomes drowsy and sleepy, the heart rate and breathing are affected, among other things. By integrating sensors in the car interior, for example in the seat belt and the steering wheel, the variations in heart rate and respiration can be monitored in real time. Smartwatches and bracelets with built-in sensors, worn by the driver, can also be used to register physiological signals.</div> <div><br /></div> <div><strong>Promotes road traffic safety and health </strong></div> <div>“Traffic safety is in focus, but also to handle sudden acute illness, to follow-up on chronic health conditions or treatments, and to take the adequate actions in the event of traffic accidents”, says Bengt Arne Sjöqvist, Professor of Practice Emeritus at Chalmers, and since many years active in the area of digital health.</div> <div><br /></div> <div>“In the digitally connected safety services that we at Autoliv are developing, the health aspects are becoming increasingly important”, says Pernilla Arnell, responsible for business development within Autoliv. “Making the driver aware of health conditions that may affect driving is a natural next step. Our surveys show that there is a positive attitude – ​<span></span> <span style="background-color:initial">not least among middle-aged women </span><span style="background-color:initial">– </span><span style="background-color:initial">towards various aids that promote safe driving</span><span style="background-color:initial">.”</span></div> <div></div> <div><br /></div> <div>The technological advances are governed in that direction also via legal requirements and scoreboard assessments of safety functions at the EU level, which regulates and rewards the implementation of sleep detection systems in new cars.</div> <div><br /></div> <div><strong>Shifting focus from the vehicle to the driver</strong></div> <div>“As technology for autonomous steering and assisted driving becomes more common in cars, the drivers will probably get tired faster, especially at night, when the task to drive is less stimulating”, says Johan Karlsson, Senior Research Engineer at Autoliv Research. “That makes systems for reliable detection of sleepiness even more important.”</div> <div><br /></div> <div>Today, many cars already have some kind of built-in sleepiness detection that is based on the driver's performance by monitoring how the vehicle moves on the road. However, if the driver's unfocused driving is corrected by the car's driver assistance system, this loses its significance as a measure of sleepiness. In the future, there will be other, more direct ways of measuring drowsiness, where the focus is set on the driver's physiology and not on determining the driver's performance through the the behaviour of the car.</div> <div><br /></div> <div>A hardware has been developed by Autoliv, which connects sensors in the car with online services. This also makes it possible, for example, to use information from fitness watches or other smart watches, to transfer your driver profile to vehicles in carpools, and to take advantage of individual adaptation of sleepiness detection.</div> <div><br /></div> <div>“The results are interpreted by an algorithm trained by artificial intelligence, which we at Chalmers have developed in collaboration with Autoliv and VTI”, says Stefan Candefjord. “The system recognises the signs of a person going into drowsiness, thus having an impaired ability as a driver. Data which is collected during the drive can be shared to the cloud, and of course also be used by systems in the car that ensure that the driver, if possible, focuses his or her attention again or gets a recommendation to take a break from driving.”</div> <div><br /></div> <div>“We are currently evaluating whether unobtrusive sensors can provide as valuable information as medical-grade ECG sensors”, says Ke Lu, Postdoctoral researcher, working in the project group at Chalmers.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Digital%20hälsa%20möter%20fordonsindustrin/COPE_hardware_750px.jpg" class="chalmersPosition-FloatLeft" alt="Driver on a country road" style="margin:5px" /><br /><br /><br /></div> <div><em>Test drivers will receive a small black box to put on top of the instrument panel, which collects data on the driver's respiration and heart rate.

In parallel, the physiological signals are registered by heart rate monitors, and for some drivers also by prototype sensors in the steering wheel and seat belt.”</div> <div><br /></div> <div>Data collected is used to further calibrate the algorithms.

Simply put, he works with technology to move information from one place to another. He is also the director of the competence center ChaseOn, which develops antenna systems for anything from high-speed mobile networks and self-driving cars to safe baby food and medical diagnostics. He has also been involved in developing a global standard for 5G, which has resulted in frequent questions by media about the development of mobile networks.

It is soon in everyone’s pocket. And recently, the first step was taken towards starting the next generation – 6G. Chalmers, together with a number of other academies and industries, is participating in a major EU project that will set the framework before the work on the new 6G net can even begin. In eight to ten years, the network will then be available to the public. But it is still too early to predict which new technological innovations 6G will involve, says Erik Ström. </div> <div><span style="background-color:initial">“As they say, the only thing we know for certain is that 6G comes after 5G. Of course, we have some thoughts about which new services we think will be important, but it is difficult to know beforehand what will become a commercial hit. As an example, we believe that developing an accurate positioning in six dimensions will be useful. It will enable you to determine, for example, where and on which floor in a large high-rise building a mobile phone is located, and also in which direction that phone is pointing, i.e. compass direction plus upwards/downwards, much like with a combined compass and spirit-level.”</span></div> <div><br /></div> <div><strong>Worried about the societal development</strong></div> <div>As the mobile network is expanding, so are the reports of 5G masts being set on fire.

This recommendation is based on a background report produced by a group led by Ida-Maja Hassellöv, professor at Chalmers.</b></p>​On September 24, the International Council for the Exploration of the Sea (ICES) publish a so-called Viewpoint. A report that aims to provide impartial evidence-based analyses of marine science topics of potentially high importance to managers and society. This year's Viewpoint is about effects on the marine environment as a result of wide-scale scrubber use. The r​ecommendation is clear: do not discharge scrubber water. <div><br /></div> <div>A scrubber is used to clean ship exhaust gases, especially regarding sulfur oxides. By washing the exhaust gases in a fine spray of seawater, the emission of acidifying sulfur oxides to the atmosphere is reduced. However, the scrubber discharge water is very acidic and may contain other pollutants such as heavy metals and organic substances. </div> <h2 class="chalmersElement-H2"><span>A fossil fuel 'lock-in' </span></h2> <div><span style="background-color:initial">The Chalmers researcher Ida-Maja Hassellöv, a professor in maritime environmental science, has led the work, coordinating a group of 17 researchers from different countries to produce a background report on the effects of scrubber discharge water on the marine environment. She describes the discharge water from scrubbers as a toxic cocktail of various substances. The emissions from scrubber use are also extensive regarding metals and organic pollutants, compared with the content of other types of wastewater generated on board ships. Of the more than 8,000 vessels that operated in the Baltic Sea in 2018, less than 2% were equipped with scrubbers. Despite this, the scrubber water from these ships is estimated to have released ten to a hundred times more metals and organic pollutants to the marine environment, compared to what was released in total from all other wastewater generated on board on all 8,000 ships. </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“It is really negative for the marine environment; beyond pollutants, the scrubber discharge water is often heavily acidic and sometimes contains high levels of nutrients. The use of scrubbers also means a continued opportunity for ships to burn heavy fuel oil, which means a lock-in in the use of fossil fuels. In addition, there are indications that ships’ use of heavy fuel oil can also be used to get rid of toxic waste” says Ida-Maja Hassellöv. </span></div> <h2 class="chalmersElement-H2"><span>The consequences are difficult to survey </span></h2> <div><span style="background-color:initial">There are major commercial interests in scrubbers, both from manufacturers and the oil industry. Ida-Maja Hassellöv hopes that ICES' scientific analysis and recommendation on discharges of scrubbing water from a marine environment perspective will be an important signal to, for example, the UN International Maritime Organization, IMO and governments around the world that this is something that needs to be better regulated. The consequences of the discharge of scrubber water are today difficult to assess. They include both acidifying effects, ecotoxicological effects and sometimes eutrophication. </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“The effects of chemical mixtures are something that we know very little about. Last year, Christina Rudén, a professor in regulatory toxicology at Stockholm University, suggested in a government’s official investigation that all limits for toxic chemicals should be lowered to one-tenth of today's levels because we don’t know enough about what the safe levels should be when it comes to chemical mixtures” says Ida-Maja Hassellöv. </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">In several ports around the world, discharges of scrubber water have been banned and in Sweden, two ports have chosen to ban discharges, but there is no national regulation in place. However, the issue is under investigation and together with her Chalmers colleagues Erik Ytreberg and Anna Lunde Hermansson, Ida-Maja Hassellöv has submitted a background report to the Swedish Transport Agency and the Swedish Agency for Marine and Water Management, which will propose a national strategy for the Government Offices this autumn.</span><span style="background-color:initial">​</span><br /></div> <div><h3 class="chalmersElement-H3"><span>Read more</span></h3></div> <div><a href="http://ices.dk/news-and-events/news-archive/news/Pages/ViewpointSSDW.aspx"><span>Viewpoint - </span><span style="background-color:initial">ICES highlights risks associated with ships' scrubber discharge water</span>​</a><span style="background-color:initial"></span></div> <div><span><a href="/en/departments/m2/news/Pages/The-fumes-of-concern-are-sent-below-the-surface-.aspx">The fumes of concern are sent below the surface​</a><br /><a href="/en/staff/Pages/idamaja.aspx">Ida-Maja Hassellöv</a></span></div> <div></div>Thu, 24 Sep 2020 08:00:00 +0200https://www.chalmers.se/en/news/Pages/Areas-of-Advance-Award-for-wireless-centre-collaboration.aspxhttps://www.chalmers.se/en/news/Pages/Areas-of-Advance-Award-for-wireless-centre-collaboration.aspxAreas of Advance Award for wireless centre collaboration<p><b>​Collaboration is the key to success.

The two directors – Jan Grahn, Professor at Microtechnology and Nanoscience, and Erik Ström, Professor at Electrical Engineering – saw that close collaboration would result in obvious advantages. In 2017, the two centres therefore formed a joint consortium, bringing together a large number of national and international companies.</div> <div>“Formally, we are still two centres, but we have a joint agreement that makes it easy to work together”, says Erik Ström.</div> <div>“For Chalmers, it is a great strength that we are now able to see the whole picture, beyond departmental boundaries and research groups, and create a broad collaboration with the companies.

The technical development has, of course, been extreme; in 2007, as GigaHertz and ChaseOn were launched in their current forms, the Iphone hit the market for the very first time. Technology that today is seen as a natural part of everyday life – such as mobile broadband, now almost a necessity alongside electricity and water for most of us – was difficult to access or, at least, not to be taken for granted.</div> <div>The companies have also changed, which is noticeable in the flora of partners, not least for GigaHertz.</div> <div>“In the early 2000s, when our predecessor CHACH centre existed, the collaboration with Ericsson was dominant. Today, we collaborate with a much greater diversity of companies. We have seen an entrepreneurial revolution with many small companies, and even though the technology is basically the same, we are now dealing with a multiplicity of applications”, says Jan Grahn.</div> <div>As technology and applications developed and changed, the points of contact between the two centres grew, and this is also what initiated the merger:</div> <div>“When we started, in 2007, we were competing centres. The centres developed completely independently of each other, but have now grown into one. The technical convergence could not be ignored, we simply needed to start talking to each other across competence boundaries – which in the beginning was not so easy, even though today we view this as the obvious way forward”, says Erik Ström.</div> <h2 class="chalmersElement-H2">Research to benefit society</h2> <div>The knowledge centres are open organisations, where new partners join and collaborations may also come to an end. Several companies are sometimes involved together in one project. Trust and confidence are important components and take time to build. One ground-rule for activities is the focus on making research useful in society in the not too distant future.</div> <div>Chalmers Information and Communication Technology Area of Advance can take some of the credit for the successful collaboration between GigaHertz and ChaseOn, according to the awardees.</div> <div>“Contacts between centres were initiated when I was Director of the Area of Advance”, says Jan Grahn.</div> <div>“The Areas of Advance show that we can collaborate across departmental boundaries, they point to opportunities that exist when you work together.”</div> <h2 class="chalmersElement-H2">They believe in a bright future</h2> <div>The competence centres are partly financed by Vinnova, who has been nothing but positive about the merger of the two. Coordination means more research for the money; partly through synergy effects and partly by saving on costs in management and administration.</div> <div>The financed period for both GigaHertz and ChaseOn expires next year. But the two professors are positive, and above all point to the strong support from industry.</div> <div>“Then, of course, we need a governmental financier, or else we must revise the way we work. I hope that Vinnova gives us the opportunity to continue”, says Erik Ström.</div> <div>“The industry definitely wants a continuation. But they cannot, and should not, pay for everything. If they were to do so, we would get a completely different type of collaboration. The strength lies in sharing risks in the research activities by everyone contributing funds and, first and foremost, competence”, says Jan Grahn.</div> <h2 class="chalmersElement-H2">“Incredibly fun”</h2> <div>Through their way of working, Erik Ström and Jan Grahn have succeeded in renewing and developing collaborations both within and outside Chalmers, attracting new companies and strengthening the position of Gothenburg as an international node for microwave technology. And it is in recognition of their dynamic and holistic leadership, that they now receive the Areas of Advance Award.</div> <div>“This is incredibly fun, and a credit for the entire centre operation, not just for us”, says Erik Ström.</div> <div>“Being a centre director is not always a bed of roses. Getting this award is a fantastic recognition, and we feel great hope for the future”, concludes Jan Grahn.<br /><br /><div><em>Text: Mia Malmstedt</em></div> <div><em>Photo: Yen Strandqvist</em></div> <br /></div> <div><strong>The Areas of Advance Award</strong></div> <div>With the Areas of Advance Award, Chalmers looks to reward employees who have made outstanding contributions in cross-border collaborations, and who, in the spirit of the Areas of Advance, integrate research, education and utilisation.

In June, the collaboration agreement was renewed for another three years.</b></p><div>​<span style="background-color:initial">The new agreement – signed by Chalmers' President Stefan Bengtsson and Mats Moberg, Senior Vice President Research &amp;Development at Volvo Cars – implies that Volvo Cars continues to be one of Chalmers so-called strategic partners. The strategic partnerships are characterized by extensive research collaborations, joint educational initiatives, and a diversity in collaboration across Chalmers research disciplines as well as focus on highlighted topics (<a href="/en/collaboration/strategic-partnerships/Pages/default.aspx">read more about the strategic partnerships here</a>).</span></div> <div><span><h2 class="chalmersElement-H2">&quot;Chalmers takes an exceptional position&quot;</h2></span></div> <div>The academy is central for Volvo Cars, and will remain so in the future, says Mats Moberg:</div> <div> </div> <div> “For our provision of competence through excellent educational programmes, for the present through lifelong learning, and for our future development as a company with knowledge through collaborations in research and innovation. As a university, Chalmers takes an exceptional position as our main collaboration partner in all these areas”, he says, and continues:</div> <div> </div> <div>“We collaborate in student thesis projects, courses and educational programmes. Volvo and Chalmers work together in international projects, from the United States in the west to China in the east, and 60 percent of our industrial PhD students in Volvo Cars Industrial PhD Program – VIPP, which we established in 1999 – are now enrolled at Chalmers.”<br /><br /></div> <div> </div> <div>The great collaboration is not only due to the fact that Chalmers is close to Volvo Cars head office as the company is global, Mats Moberg points out.</div> <div> </div> <div>“It is simply because Chalmers offers both excellency and relevance in collaboration forms that have worked splendidly and enduring over the years.”</div> <h2 class="chalmersElement-H2">Major and rapid changes in the transport system</h2> <div> </div> <div>The first partnership agreement was signed with Volvo Cars back in 2013. The company is today one of Chalmers’ largest strategic partners, says Sinisa Krajnovic, Director of Chalmers Transport Area of Advance. The renewal of the agreement means an opportunity to further develop the partnership.</div> <div> </div> <div>“We are in a time period with major and rapid changes in the transport system, including new technologies and mobility behaviors. The collaboration with Volvo Cars gives us an expanded opportunity to develop our research and education, and our utilization within the transport system, making us even more able to contribute to the development of sustainable, road-safe and efficient transport.”</div> <div> </div> <div><br />For Chalmers, the strategic partnerships are a tool for updating research and education, ensuring the research to be conducted at the forefront, as well as offering education to the very best future engineers. Through the partnerships, strategies are synchronized and the parties also have the opportunity to build joint infrastructures and test beds that would not have been possible without continuous dialogue.</div> <div> </div> <div><div>“In my opinion, the Areas of Advance have an important role to play in coordinating, as hosts of the partnerships”, says Sinisa Krajnovic.</div> <h2 class="chalmersElement-H2">Electrification and automation important areas</h2></div> <div> </div> <div>Chalmers and Volvo Cars already have a multitude of joint investments in research infrastructures, competence centers and research projects.</div> <div> </div> <div>“We also look forward to working together in the new, big investment in electromobility research, SEEL – Swedish Electric Transport Laboratory – where Volvo Cars plays an important part. Electrification is an important area of collaboration for both Chalmers and Volvo Cars, as well as automation”, says Sinisa Krajnovic.<br /><br /></div> <div> </div> <div>And Mats Moberg agrees:</div> <div> </div> <div>“The renewal of our agreement is a confirmation of our mutual ambition to further sharpen our collaboration. This to continue towards added excellency, and to continue our work towards our goal of a sustainable, safe and personal mobility, but also to be leading in electrification, autonomous drive and digitalization.”<br /><br /></div> <div> </div> <div>The renewed agreement is for three years, and automatically extended for another two years thereafter.<br /><br /></div> <div> </div> <div>Text: Mia Malmstedt</div> <div> </div> <div>Photo: Erik Axén, Volvo Cars</div> <div> </div> <div>​<br /></div> <div> </div>Fri, 26 Jun 2020 16:00:00 +0200https://www.chalmers.se/en/departments/m2/news/Pages/Safety-system-that-understands-human-behavior-will-save-cyclists.aspxhttps://www.chalmers.se/en/departments/m2/news/Pages/Safety-system-that-understands-human-behavior-will-save-cyclists.aspxSafety system that understands human behavior will save cyclists<p><b>​In the project MICA, sponsored by FFI, researchers from Chalmers have investigated the interaction among cyclists and vehicles. They have developed a smart safety system that could reduce the number of fatal accidents in traffic with cyclists involved by up to 96 percent.</b></p><p>​The smart safety system continuously predicts what a driver should do to overtake a cyclist safely. The system acts when it sees a mismatch between what the driver does and what she or he should be doing. By collecting data from a test track, researchers have investigated how different factors affect behaviour in overtaking manoeuvres with oncoming traffic. Based on the data, the researchers have modelled how vehicles approach cyclists and integrated the models in frontal collision warnings and automatic emergency braking systems. The safety benefits from the systems have been evaluated through virtual simulation. </p> <p><span style="background-color:initial">“The smart collision warning alone promises a reduction of cyclists fatalities by 53-96 percent and a reduction of cyclists serious injuries by 43-93 percent” says Marco Dozza, professor at the Division of Vehicle Safety. </span></p> <h2 class="chalmersElement-H2"><span>Supports the Swedish car industry</span></h2> <p>The research results support the Swedish car industry in maintaining its world-leading role in designing advanced solutions for active safety. The models developed in the project can predict the driver's intention when approaching a cyclist from behind to perform an overtaking. These models can be integrated with existing systems and provide input on how an automated vehicle should safely and comfortably overtake a cyclist. </p> <p><span style="background-color:initial">&quot;Our research supports the development of safety systems that can help a driver or an automated vehicle interact with cyclists safely. We have taken the driver models from a TRL level of 1-2 to a TRL level of 5 for this scenario&quot; says Marco Dozza. </span></p> <p><span style="background-color:initial">TRL, Technology Readiness Level is a designation for a technology's maturity and associated technological risk.

This was the assignment from Volvo Penta, and students from Chalmers and Penn State University worked together to solve the problem. The result was award-winning!</b></p>​<span style="background-color:initial">Boats powered by electricity have become increasingly popular over the last years, but most marinas lack sufficient infrastructure to meet the need for charging. With this problem at hand, Volvo Penta announced a bachelor thesis last fall to get suggestions for solutions. The proposed project was a so-called Capstone project, and as such part of Chalmers strategic partnership with the Volvo Group, and to be carried out by students at Chalmers along with students from Penn State University in Pennsylvania, USA.<br /><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_puffbilder/AgnesAime_350.jpg" alt="" style="margin:5px" /><br /></span><div><div>As a result, four students from Chalmers and four from Penn State have worked together in this project throughout the spring. And even though the Corona pandemic got in the way of the travel plans, it has been a successful collaboration – in fact, so successful that the students’ Solar Wharf Garage was awarded with first price in the Lockheed Martin Best Project Award. This is the second time a Capstone project wins first price since the start of the collaboration six years ago.</div> <h2 class="chalmersElement-H2">&quot;Project of good quality&quot;<br /></h2></div> <div>Agnes Tunstad and Aime Vesmes were part of the winning team. Initially, they were both attracted by the opportunity to gain international contacts, but that’s not all:</div> <div>“It seemed to be a fun project, and the collaboration with a global industry did not make it any less interesting”, says Aime Vesmes, and Agnes Tunstad nods and adds:</div> <div>“I like boats, and I like renewable energy! In addition, the project seemed to be of good quality.”<br /><br /></div> <div>Aime Vesmes is ending her third year at Mechanical engineering – together with the other two from Chalmers, Gustaf Malmsjö and Johan Kinell – while Agnes Tunstad is studying Automation and mechatronics. The project therefore entailed not only cooperation across national borders, but also across Chalmers’ programmes.</div> <div>“Much of the content is the same in our courses, but there is also a lot of differences. I’m happy for everything that this project taught me about the product development process, as this was completely new to me. Had it not been for my project colleagues from Mechanical engineering, this would have been much more difficult”, says Agnes Tunstad.<img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_puffbilder/Hamn_350.jpg" alt="" style="margin:5px" /><br /><br /></div> <div>The project has required a lot of learning, and a lot of time for feasibility studies for all of them:</div> <div><div>“Yes, the real challenge has been to learn everything we needed to know. For example, I didn’t know how solar cells worked, or what to think about in a marine environment. We have really learned along the way”, says Aime Vesmes.</div> <h2 class="chalmersElement-H2">Two-boat garage with 18 solar panels</h2></div> <div>The final product is a two-boat garage where the boats are charged by nine solar panels each. According to the calculations, the payback period is 13 years, and the estimated structural lifetime more than twice as long. The material choices for the garage are guaranteed to hold the least possible risk of rust or other damage, and the panels can also be folded down to protect them from hard weather.<br /><br /></div> <div>Their collaboration has been performed via Zoom, a digital tool for video communication. The eight students were careful not to divide the project into smaller pieces but to try – as far as possible – to cooperate in all parts. This is reflected in the report, they say; otherwise the report could have ended up “choppy”, as a reflection of the fact that different parts were carried out by different persons. The group believe that this is one of the reasons why they won the award. And as Agnes Tunstad says:</div> <div>“What’s the point of a global project if you do not work together?”<br /><br /></div> <div>The response from Volvo Penta has been nothing but positive. In the beginning, the students were in close contact with their contact person, but he also emphasized that he did not want them to be too influenced.</div> <div><div>“If our ideas can bring value to Volvo, I’m happy. That’s what it is all about; for us to be able to give ideas for solutions”, says Aime Vesmes.</div> <h2 class="chalmersElement-H2">Changed plans for the exhibition an advantage</h2></div> <div>The plan was for the Chalmers’ students to travel to Penn State in April. The trip had to be cancelled, for obvious reasons. But the restrictions imposed by the Corona pandemic have not only been negative. For the project participants at Chalmers, winning the award became even more fun as they were able to participate in a video presentation at the virtual exhibition from which the winner was selected.</div> <div>“Had it just been an exhibition with posters, as it usually is, it probably wouldn’t have felt as satisfying. In that case, we simply would not have been as involved. But now, thanks to the video, we were all included on equal terms”, concludes Agnes Tunstad.<br /><br /></div> <div>Note: <a href="https://psu.mediaspace.kaltura.com/media/AB+Volvo+Penta+1/1_icgww547">Watch the students’ video presentation here!​</a><br /><br /></div> <div>Text: Mia Malmstedt</div> <div>Photo: Charles Strömblad (photo of Agnes Tunstad and Aime Vesmes) and Gustaf Malmsjö (Solar Wharf Garage and Öckerö marina) </div> <div>​<br /></div> Thu, 28 May 2020 12:00:00 +0200
