A fuel that has become increasingly popular is liquefied natural gas, known as LNG (Liquefied Natural Gas). It’s already used today in cruise ships, passenger ships and container ships. <div><br /></div> <div>In the risk analysis for the ships' panel structures that have an important structural function, one has in the design assumed that LNG leakage will very rarely occur and to some extent taken various measures to ensure that LNG does not come into contact with the panels. </div> <div><br /></div> <div>There is currently a lack of knowledge about how an LNG leakage would affect the properties of the metallic material if it occurs at the same time as the ship is out in severe weather where it’s exposed to difficult wind and wave conditions. The purpose of the project has been to compare physical model experiments and results from computer-based simulations. </div> <div><br /></div> <div>“With the right knowledge, models and numerical analysis technology, we can ensure that the design of panel structures in ships that are exposed to arctic or cryogenic temperatures meets the expectations and requirements they have concerning the loads that may occur” says Jonas Ringsberg. </div> <h3 class="chalmersElement-H3">The results applied with commercial software </h3> <div>The project's simulation models and results regarding buckling strength at arctic and cryogenic temperatures have already been applied with commercial software to help the industry develop revised guidelines for the design of ship structures exposed to these low temperatures. This in turn will lead to that ships that are now being developed having higher safety in the event of LNG leakage. </div> <h3 class="chalmersElement-H3">Tests in ICASS - unique research infrastructure </h3> <div>The physical tests were performed in a unique test facility in South Korea called The International Center for Advanced Safety Studies (ICASS) and are operated by the Korea Ship and Offshore Research Institute (KOSORI) located at Pusan National University in South Korea. With the collaboration, Chalmers has been included as a research partner, which means access to the unique facility. Something that pleases Jonas Ringsberg. </div> <div><br /></div> <div>&quot;It's very positive. The corresponding testing is not possible in Europe&quot; says Jonas Ringsberg. </div> <div><br /></div> <div>The Swedish Research Council project has the name &quot;Fundamental research on the ultimate compressive strength of ship stiffened plate structures at Arctic and cryogenic temperatures&quot; and received funding from the Swedish Research Council’s bilateral cooperation between Sweden and South Korea.</div> <h3 class="chalmersElement-H3">Read more</h3> <div><a href="https://research.chalmers.se/en/project/?id=8736">Fundamental research on the ultimate compressive strength of ship stiffened plate structures at Arctic and cryogenic temperatures</a><br /></div> <div><a href="https://www.lrfoundation.org.uk/en/impact-stories/kosori-test-facilities/">Impact Story from Lloyd's Register Foundation: Opening the doors of large-scale testing facilities​</a><br /></div>Thu, 25 Feb 2021 09:15:00 +0100https://www.chalmers.se/en/departments/m2/news/Pages/Access-to-research-labs-provides-satisfied-students.aspxhttps://www.chalmers.se/en/departments/m2/news/Pages/Access-to-research-labs-provides-satisfied-students.aspxAccess to research labs provides student satisfaction<p><b>​By using research infrastructure in teaching, the understanding of the subject increases. The feedback from the students is very positive. These are the experiences of the teaching staff in vehicle engineering and autonomous systems.</b></p>​Simone Sebben is head of division and professor at the Division of Vehicle Engineering and Autonomous Systems. Together with her colleagues, she works with courses in vehicle aerodynamics and vehicle engineering, among other things. Some of the elements in the courses are located in research infrastructure at Chalmers. An example of such infrastructure is Chalmers wind tunnels, which go by the name Chalmers Laboratory of Fluids and Thermal Sciences. <div><br /></div> <div>“To understand vehicle aerodynamics, it is important that students can do something practical. In reality, seeing what happens to, for example, aerodynamic drag, when they make a change to a vehicle with their own hands is very good for their learning&quot; says Simone Sebben. </div> <div><br /></div> <div>That type of learning is only possible in a wind tunnel, she says. The students work in groups and together they make different configurations which they test. Then they get to present their results and write a report. Simone sees this as the most important moment because the students then must put into words the results they experienced. </div> <h3 class="chalmersElement-H3">Good for the students' resume </h3> <div>“We get very positive feedback. It increases interest in the course and constitutes a good addition to the students' resume. They can write that they have worked in a wind tunnel and that they know the basic principles of how one works, which is welcomed by the industry&quot; says Simone Sebben who herself has a background from having worked with aerodynamics at Volvo. </div> <div><br /></div> <div>In addition to the wind tunnel, the students have also gained access to Asta Zero, the driving simulator Caster as well as Revere and Intelligent vehicles and robots laboratory, which deals with self-driving vehicles, active safety and vehicle dynamics. </div> <h3 class="chalmersElement-H3">Unique for Chalmers </h3> <div>Having this kind of infrastructure available to students makes Chalmers unique. This is not the norm, says Alexey Vdovin, a researcher in the Division of Vehicle Engineering and Autonomous Systems, who also uses the infrastructure in his teaching. </div> <div><br /></div> <div>“It is highly appreciated by students as they can get experience in Computational Fluid Dynamics but also in real-life testing. Students can compare the simulation results to real-life behaviour of the airflow. They learn more by doing it this way” says Alexey Vdovin. </div> <div><br /></div> <div>Valery Chernoray is a professor at the Division of Fluid Dynamics and responsible for the wind tunnel. He agrees with the teachers' observations. He believes that even if an engineer uses virtual tools, an engineer must also be able to build things in reality. </div> <div><br /></div> <div>&quot;The connection between virtual tools and reality is central and the laboratories provide this necessary link&quot; he says. </div> <h3 class="chalmersElement-H3">Do you want to work in a wind tunnel during your studies? </h3> <div>Then you should choose the master's program Mobility engineering. The development of autonomous and electric vehicles is rapidly changing the transport industry. Chalmers University of Technology is now launching a master's programme that will prepare engineers to face the industry's major transformation and the challenges that lie ahead. </div> <div><br /></div> <div>The new master's programme Mobility Engineering, which starts in the autumn of 2021 at Chalmers, will train engineers to develop sustainable, high-performance mobility solutions and handle challenges within electrification, automation, simulation, and the reliability of vehicles. </div> <h3 class="chalmersElement-H3">Read more </h3> <div><a href="/en/education/programmes/masters-info/Pages/Mobility-Engineering.aspx">Mobility Engineering </a></div> <div><a href="/en/departments/m2/simulator-labs/labs/chalmerswindtunnels/Pages/default.aspx">Chalmers Laboratory of Fluids and Thermal Sciences</a></div> <div><a href="/en/departments/m2/education/educational-resources/Pages/Driving-Simulator.aspx">The Driving Simulator Caster</a></div> <div><a href="/en/researchinfrastructure/revere/Pages/default.aspx">Caster Revere</a><br /><a href="https://www.astazero.com/">Asta Zero​</a></div>Thu, 11 Feb 2021 13:45:00 +0100https://www.chalmers.se/en/departments/e2/news/Pages/Revere-celebrates-five-years-of-vehicle-research.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/Revere-celebrates-five-years-of-vehicle-research.aspxRevere celebrates five years of vehicle research<p><b>​Since the start, in autumn 2015, Revere – Chalmers&#39; vehicle laboratory – has established itself as a full-fledged research infrastructure for academia and the automotive industry in western Sweden. Originating from road traffic research, the scope of Revere now also includes marine vessels and electrified vehicles.​</b></p>​<span style="background-color:initial">Self-driving vehicles, active safety and vehicle dynamics are the three areas in focus for Revere, Resource for Vehicle Research at Chalmers.</span><div><br /><span style="background-color:initial"></span><div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Revere%20firar%20fem%20år%20av%20fordonsforskning/fredrik_von_corswant_230px.jpg" class="chalmersPosition-FloatRight" alt="Fredrik von Corswant" style="margin:5px;width:200px;height:260px" />“Vehicle researchers and companies in the transport sector are welcome to contact us with their ideas and projects to get help to transform them from theory to reality”, says Fredrik von Corswant, Director of Revere.</div> <div><br /></div> <div>In collaboration with Revere, technologies, theoretical models and algorithms can be developed and tested on real vehicles and in real traffic environments, or at <a href="https://www.astazero.com/" target="_blank"><div style="display:inline !important">the AstaZero test track.</div></a></div> <a href="https://www.astazero.com/" target="_blank">​</a><div><span style="background-color:initial">“We write research appli</span><span style="background-color:initial">cations in collaboration with researchers and industry partners, enabling a tailor-ma</span><span style="background-color:initial">de test phase that gets the most out of the results”, he declares.</span><br /></div> <div><br /></div> <div><strong>Full-scale vehicles and models </strong></div> <div>In the lab at Lindholmen in Gothenburg, Revere has several vehicles of different kinds that are used in the research activities, for example a full-scale truck as well as cars and also smaller radio-controlled model vehicles. The smaller vehicles are often used in the teaching of students.</div> <div><br /></div> <div>By adapting the vehicles to the current projects and providing them with different types of sensors and equipment for data logging, communication technology and more, data can be collected and the theories refined and verified.</div> <div><br /></div> <div>“Our flexible, in-house developed software platform OpenDLV is our greatest asset”, says Fredrik von Corswant. “Only imagination sets the limits on what it can be used for in vehicle research, I would say. For example, it is possible to connect remotely to the vehicles while test driving, in case there is something that you immediately want to adjust in the software. Another advantage is that the platform can handle large amounts of data and is able to compress video, without losing data that is important to the algorithms.”</div> <div><br /></div> <div><strong>Real tests give more reliable results </strong></div> <div>Revere often works with long vehicles and combinations of vehicles, for example a tractor unit that is connected to two semi-trailers and a converter dolly forming a High Capacity Transport, HCT vehicle. Such a combination is longer than what is normally allowed to drive on public roads in Sweden today. In the vehicle lab, research and tests are performed on, for example, how to stabilize long vehicle combinations so that they do not tip over.</div> <div><br /></div> <div>“We are also developing protocols for the communication between vehicle units”, Fredrik continues. “For example, if the tractor uses the brakes, a connected electrical dolly should not continue to propel forward.”</div> <div><br /></div> <div>Conducting tests in real life provides supplementary and more reliable information, than computer simulations alone can supply.</div> <div><br /></div> <div>“Only full-scale tests cover all the factors that affect the vehicle. For example, there are often disturbances that interfere with signals from sensors, inertia due to the weight of the vehicle, and also effects such as delays in the system, limitations in computer capacity, and more. Tests can provide answers to questions concerning how sensors act in bad weather or how the grip of the tires on the road surface behave depending on road conditions. This is often very difficult to determine with theoretical models alone.”</div> <div><br /></div> <div>Revere's software platform can also be used to perform simulations. Real traffic data can be mixed with simulated data. For example, how would a self-driving car behave if there is an unexpected object like a dustbin, or other obstacle, on the road?</div> <div><br /></div> <div>“We also compile datasets, such as film sequences, that are collected and created by our sensors in traffic situations of various kinds. We then share the data as open source with those who want to test their own  algorithms.”</div> <div><br /></div> <div>Data created in the test vehicles is automatically uploaded to Revere's cloud server. The latest addition is data from a bus, that in early 2021 will run in regular traffic between two cities in India. In connection with the cloud server, Revere also offers analyses of data in a computational cluster, which enables, for example, training of systems for machine learning.</div> <div><br /></div> <div>At the lab, more humanistic aspects are also studied, such as research into driver behavior and how surrounding road users perceive the interaction with self-driving vehicles since there is no driver to make eye contact with.</div> <div><br /></div> <div><strong>Research also in marine settings </strong></div> <div>For a couple of years now, Revere has entered the field of marine vessels, mainly in collaboration with RISE. A pilot boat in the port of Gothenburg is available for research projects, and also a catamaran platform and some models.</div> <div><br /></div> <div>“The sensor technology used does not differ much from land to sea, apart from the radar systems. We have transferred a lot of our existing systems into marine applications”, says Fredrik. “I think there is a great need and demand for research on automation in the marine settings, from academia as well as from the industry. This is definitely an area for further expansion in the future.”</div> <div><br /></div> <div><strong>A venue to be proud of </strong></div> <div>Looking back at the first five years of the lab, what is he as a Director most proud of?</div> <div><br /></div> <div>“We have successfully carried out a number of demonstrations of cutting-edge research, and our in-house developed software platform stands out well compared to the equivalents being developed at vehicle companies”, says Fredrik von Corswant. “Today, Revere is a venue where researchers and developers from various organizations and disciplines meet. That provides exciting cross-border connections and creates ideas for new innovations.”</div> <div><br /></div> <div>The demand for a vehicle research infrastructure remains stable for the foreseeable future. We have probably only entered the first phase of the societal development that self-driving cars and electrified vehicles of various kinds are bringing.</div> <div><br /></div> <div>”I hope that Revere in the future can attract more researchers and companies to be active collaborating partners. Our goal is to continue to build competence in automation and active security in the region, to provide a good recruitment base for industry and research institutes”, concludes Fredrik von Corswant.</div> <div><br /></div> <div>Text: Yvonne Jonsson<br />Photo: Henrik Sandsjö</div> <div><br /><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Revere%20firar%20fem%20år%20av%20fordonsforskning/RevereTestfordon_Lindholmen_201016_05_750x422px.jpg" class="chalmersPosition-FloatRight" alt="Revere at Lindholmen" style="margin:5px" /><br /><br /></div> <div><br /></div> <div><br /></div> <div><h2 class="chalmersElement-H2" style="font-family:&quot;open sans&quot;, sans-serif"><span style="font-family:inherit;background-color:initial">Examples of research projects</span><br /></h2></div> <div> <div><a href="https://research.chalmers.se/en/project/?id=8349" target="_blank">I-dolly, a self-propelled truck trailer without driver or car </a><br /></div> <div>Revere is testing, in collaboration with, among others, Volvo Trucks and researchers from Chalmers, an intelligent converter dolly, that has its own electrical propulsion and steering.

An international research team led by Chalmers has now developed concrete guidelines for how the batteries should be charged and operated, maximising efficiency while minimising the risk of short circuits.</b></p>​<span style="background-color:initial">Lithi</span><span style="background-color:initial">um metal batteries are one of several promising concepts that could eventually replace the lithium-ion batteries which are currently widely used – particularly in various types of electric vehicles.</span><div><span style="background-color:initial"><div>The big advantage of this new battery type is that the energy density can be significantly higher. This is because one electrode of a battery cell – the anode – consists of a thin foil of lithium metal, instead of graphite, as is the case in lithium-ion batteries. Without graphite, the proportion of active material in the battery cell is much higher, increasing energy density and reducing weight. Using lithium metal as the anode also makes it possible to use high-capacity materials at the other electrode – the cathode. This can result in cells with three to five times the current level of energy-density.</div> <div><h2 class="chalmersElement-H2"><span>Avoiding the ’needles’ which cause punctures and internal short circuits</span></h2></div> </span><span style="background-color:initial"><div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Dendrites_ENG_250x250.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:200px;height:200px" />​The big problem, however, is safety. In two recently published scientific articles in the prestigious journals Advanced Energy Materials and Advanced Science, researchers from Chalmers University of Technology, together with colleagues in Russia, China and Korea, now present a method for using the lithium metal in an optimal and safe way. It results from designing the battery in such a way that, during the charging process, the metal does not develop the sharp, needle-like structures known as dendrites, which can cause short circuits, and, in the worst cases, lead to the battery catching fire. Safety during charging and discharging is the key factor. </div> <div><div><br /></div></div> </span><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Shizhao_Xiong_.jpg_webb.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;height:138px;width:120px" /><div><span style="background-color:initial">“Sho</span><span style="background-color:initial">rt circ</span><span style="background-color:initial">uiting in lithium metal batteries usually occurs due to the metal depositing unevenly during the charging cycle and the formation of dendrites on the anode.

One way to measure and predict this transmission is to study our mobility, assuming that the more we move, the more people we encounter.</p> <p>Philip Gerlee and Torbjörn Lundh, Chalmers University of Technology and the University of Gothenburg, have together with several other researchers at universities and university hospitals in Gothenburg, Linköping and Lund compared the number of hospitalised covid-19 patients with mobility data in terms of public transport utilisation and mobile phone usage. This model has been shown to capture the timing of both the first and the beginning of the second wave of the pandemic.</p> <h2>Travel data from regional public transport companies</h2> <p>The comparison with mobile phone data was made for all regions in Sweden and the model turned out to perform somewhat better for larger regions than for smaller, where random effects may have a greater effect.

So how environmentally friendly are they? And how well can they help prepare for an eventual transition to a fully fossil-free vehicle sector? A unique study from Chalmers University of Technology, Sweden, now shows that PHEVs are often driven as much on electricity as ‘pure’ electric cars, with a range of about 130 km.</b></p><img src="/SiteCollectionImages/Institutioner/SEE/Profilbilder/Ahmet_Mandev_170.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><span style="background-color:initial">“In comparing a large number of multi-car households, we can see that households owning a fossil-fuel vehicle, and a PHEV,  can drive as many purely electric kilometres as a household owning a fossil fuel vehicle and a fully electric one,” says Ahmet Mandev, doctoral student at Chalmers.</span><div><br /><span style="background-color:initial"></span><div>After processing the data of four million driving days of PHEVs, Ahmet Mandev can also say how charging should take place to maximise electric power, while minimising fuel consumption and emissions.</div> <div><br /></div> <div>Despite the fact that over 20 years have passed since the first mass-produced PHEV car appeared on the market, many questions remain regarding optimal usage of such vehicles. These are questions that Ahmet Mandev, a doctoral student at the Department of Space, Earth and Environmental Science at Chalmers, aimed to answer in his doctoral studies, supervised by Associate Professor Frances Sprei.</div> <div><br /></div> <div>“The reason why we want to take a closer look at PHEVs is that there are different views on their role in electrifying personal transport. It is vital to learn as much as we can about their electrical potential, so that we can determine which policy instruments – laws, regulations and subsidies – can be most effective for such vehicles,” says Ahmet Mandev.</div> <div><br /></div> <div>In the first of the studies included in his licentiate thesis The Role of Plug-in Hybrid Electric Vehicles in Electrifying Personal Transport - Analysis of Empirical Data from North America, he processed and analysed one year of driving data for 71 households in California.</div> <div><br /></div> <div>“It is easy to see the breakdown of the kilometres for which a PHEV uses the electric motor or the internal combustion engine. But the unique thing about this study is that we looked at the household level – we mapped all the vehicles in different multi-car households. Then we saw how many kilometres a household travelled using electric power and compared that between households which own a fully electric car, or a PHEV, alongside a conventional vehicle,” he explains.</div> <div><br /></div> <div>As usual with all types of electric vehicles, range is an important factor. The study shows that households with a fully  electric car and a conventional car, drive on average 45 percent of their total kilometres on electricity, while the households with a PHEV, and a conventional car, reached 46 percent electric operation on average. This is despite the fact that the range for the vehicles at full electric operation was 130 km for the electric car – in the case of this study, the Nissan Leaf – and just under half for the plug-in hybrid - 56 kilometres.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/EoM/Profilbilder/Frances_Sprei_170x220_2.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />&quot;​The reason that the PHEV performs better, despite the considerably shorter range, is that it is taken more often for the longer journeys. So then at least some distance of those trips is driven using electricity. The figures also show that the PHEVs are more often used while another person in the household is using the conventional vehicle. The range for both BEVs and PHEVs have increased since the study, but the results are still relevant and show that plug-in hybrid vehicles have an important role to play when it comes to electrification of personal transport. As the next step it will be interesting to follow up the effect of these longer ranges on electrification rates”, says Frances Sprei.</div> <div><br /></div> <h3 class="chalmersElement-H3">Most important to charge overnight</h3> <div>Another issue that Ahmet Mandev investigated was how and when to charge a PHEV to get as many electrically driven kilometres as possible, with the lowest possible fuel consumption and emissions. In two other studies, he used about 4 million driving days of data, collected over a ten-year period from the plug-in hybrid model Chevrolet Volt. By processing the data, Ahmet Mandev calculated how often the vehicles were charged, and can thus empirically prove several points about the PHEVs.</div> <div><br /></div> <div>The most positive effects result from charging your car once a day – perhaps not so surprising. But Ahmet Mandev made a further discovery which did stand out.</div> <div><br /></div> <div>“If you decrease from charging your car every night, to 90 percent of nights, emissions triple – from 1.7 kg of carbon dioxide to 5.7 kg for 100 kilometres of driving. Fuel consumption increases in a similar way, from 0.7 liters for 100 kilometers to 2.5 liters. These are still low emissions and low levels of fuel consumption, but it is a big difference for such a small change in behaviour,” he explains.</div> <div><br /></div> <div>The PHEVs in the study achieve a high share of 76 percent of kilometers driven on electricity, provided, that they are fully charged once a day. Ahmet Mandev and Frances Sprei point out that supplementary charging during the day also gives positive effects, but for maximum effect, a full charge overnight is the best option.</div> <div><br /></div> <div>“In our studies, we focused on studying data and drawing conclusions about charging and electric operation based on that. But if one were to translate our results into policy suggestions, it would be to give more people the opportunity to recharge vehicles overnight. Currently, many people, for example those who live in apartment buildings, do not have that opportunity,” says Ahmet Mandev.</div> <div><br /></div> <div>In his further doctoral studies, he plans to make international comparisons, to see how charging patterns and electric power differ between countries with different conditions, laws and guidelines regarding PHEVs. Based on this, it will then be possible to see which policy guidelines and recommendations would make the biggest difference. </div> <div><br /></div> <div><em>Text and photos: Christian Löwhagen. </em></div> <div><em>Illustration by </em><a href="https://thenounproject.com/term/hybrid-car/1962529/"><em>Chaowalit Koetchuea​, the Noun Project</em></a><em>, arranged by Christian Löwhagen. </em></div> <div><br /></div> <div>The research was financed by the Swedish Electromobility centre and carried out in collaboration with UC Davis in California and the Fraunhofer Institute for Systems and Innovations Research in Germany. </div> <div><br /></div> </div>Fri, 04 Dec 2020 07:00:00 +0100https://www.chalmers.se/en/departments/e2/news/Pages/New-insulation-material-increases-reliability-of-electric-car-motors.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/New-insulation-material-increases-reliability-of-electric-car-motors.aspxNew material increases reliability of electric car motors<p><b>​A new insulation material for conductors increases the average lifetime of motor insulation in electric vehicles by about eight times.

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.
