The different parts are dependent on each other and it’s difficult to determine which component to take care of first and foremost to make the aircraft engine more efficient. Oskar Thulin deals with this in his PhD thesis ”On the analysis of energy efficient aircraft engines”</b></p><div><div>The aircraft engine consists of many integral components and each component will influence the overall performance of the system. Furthermore, the aircraft engine has weight and contributes to drag that must be compensated for by the engine. Using the regular way to assess performance, it is impossible to compare one component's loss to another or to directly relate an individual component's loss to the overall loss. Oskar Thulin has developed an analytical method that makes it possible to directly compare component losses in a system perspective. The method also makes it possible to include weight or caused drag in the analysis.</div> <div><br /></div> <div>&quot;This gives a much more clear picture of how big the losses are for the various components, as well as for each component type&quot; says Oskar Thulin.</div> <div><br /></div> <div>The developed framework is used to study various aircraft engines. In general, it can be said that the hot exhaust gases that leave the engine, the combustion process in itself, and the part of the kinetic energy in the exhaust that is not used to propel the aircraft forward, are the main sources of the overall loss.</div> <div><br /></div> <div>&quot;Based on the analysis you can discuss different technologies that can do something about these dominant losses. This enables a future more fuel-efficient airplane, says Oskar Thulin, who will present his PhD thesis at Chalmers University of Technology<a href="/en/departments/m2/calendar/Pages/On-the-analysis-of-energy-efficient-aircraft-engines.aspx"> on December 6 at 10:00 in HB4. </a></div></div> <div>​<br /></div> Fri, 01 Dec 2017 15:00:00 +0100http://www.chalmers.se/en/departments/m2/news/Pages/International-study--Chalmers-a-top-maritime-university-.aspxhttp://www.chalmers.se/en/departments/m2/news/Pages/International-study--Chalmers-a-top-maritime-university-.aspxInternational study: Chalmers a top maritime university<p><b>The maritime education and research provided at Chalmers University of Technology is of the highest international standard, according to the first global study undertaken in the field.  ​</b></p>​<span style="background-color:initial">This comes as no surprise to those in the division of Maritime Studies on Campus Lindholmen at Chalmers University of Technology. </span><div><br /><span style="background-color:initial"></span><div>“We’ve always hoped and believed that we would be placed high on the list and this is our confirmation. In Sweden we have long had high-quality maritime education and training, and our sailors have a reputation for competence. Over the past ten years we have also worked hard to further develop and improve the quality of the educational programmes,” says Fredrik Olindersson, Head of the Division for Maritime Studies at Chalmers.</div> <div><br /></div> <div><a href="http://iamu-edu.org/about-iamu/">The International Association of Maritime Universities (IAMU) </a>, an organisation whose members include more than sixty of the most prominent universities in the field, is behind the study. Chalmers was elected to IAMU in 2016.</div> <div><br /></div> <div>“It took over a year to become a member. You have to send in masses of documents, and they carry out site visits to make sure you live up to their high standards. Not just anyone can join. At the last Annual Meeting a couple of new universities joined, but several also applied and were not accepted,” Olindersson says. </div> <div><br /></div> <div>The study is intended to give IAMU’s member universities an idea of where their strengths lie and what they could develop. So the organisation does not provide traditional rankings but confines itself to listing, in alphabetical order, the universities that fall in the upper quartile (top 25%) in the three areas studied. </div> <div>“Chalmers University of Technology came out top in all the areas studied – global exchange, strength of research and quality of education. What is most striking about the study is that Chalmers is the most well-balanced university. That is Chalmers’ strength and one that should be nurtured and further developed,” says Takeshi Nakazawa, Executive Director of IAMU.</div> <div><br /></div> <div>Olindersson explains that Chalmers is often used as a model for a maritime educational institution around the world and that is why there are so many international visits to Chalmers. </div> <div><br /></div> <div>So what is the strength of maritime education and training in Gothenburg?</div> <div><br /></div> <div>“In addition to having competent teachers, we are one of the few educational institutions which invests a great deal in simulator education and in the work of simulator instructors. We want to maximise the impact of the expensive time spent in the simulator that forms part of the training.”</div> <div><br /></div> <div>According to Olindersson, Chalmers University of Technology is far ahead of most others in the world in its educational work on sustainability and the environment. All maritime training in the world complies with the International Convention on Standards of Training, Certification, and Watchkeeping for Seafarers (STCW) which governs the minimum standards of training, but like other IAMU members, Chalmers offers education and training at a significantly higher level.</div> <div><br /></div> <div>“The Heads of Programmes have continuously extended the programmes and have placed much greater emphasis on leadership, communication, critical thinking, and sustainability. To improve the eligibility of students, and their employability in the long term, we have also introduced a number of elective courses to the programmes. On the Master Mariner programme, students can choose to specialize in passenger and cruise ships, tanker shipping or the offshore sector. The Marine Engineer programme now includes a high voltage element, and there are elective courses in advanced ship operations, marine risks, and marine ergonomics.”</div> <div><br /></div> <div>On the research side, maritime environmental sciences, maritime human factors and marine technology are strong Chalmers areas. Read more about Maritime Studies here.</div> <div><br /></div> <div>“Global exchange mainly involves student and teacher exchanges, where we’ve increased the options in recent years by teaching the final year in English. What sets us apart is that many other universities don’t do this. However, we’ve got several exchange agreements that are working well and another couple is under way that will hopefully lead to more exchanges,” Olindersson says.</div> <div><br /></div> <div><strong>Swedish simulator centre for shipping</strong></div> <div>Campus Lindholmen houses <a href="/en/departments/m2/simulator-labs/simulators/Pages/default.aspx">Sweden’s most extensive simulator centre for education and research in shipping</a>. There are a total of nine different simulators here. In the full mission bridge simulators, it is possible to carry out complete simulations of the operations performed on a real ship: in different weather conditions, with different types of ships around you and in different areas and ports around the globe, even in narrow straits. Other simulators combine instruments that handle navigation, loading, safety, the engine room and emission control. Together with the Swedish Maritime Administration’s simulators the centre currently offers ten ships’ bridges, two coastal stations, and one maritime rescue coordination centre.</div> <div><br /></div> <a href="/en/departments/m2/research/maritimestudies/Pages/default.aspx"><div>Read more about Maritime Studies at Chalmers here.</div></a><div><strong>Contacts and further information</strong></div> <div>Fredrik Olindersson, Head of the Division for Maritime Studies at Chalmers University of Technology, +46-31-772 2648, <a href="mailto:fredrik.olindersson@chalmers.se">fredrik.olindersson@chalmers.se </a><br /><br /></div> <div>Johan Eliasson, Head of the Marine Engineer programme, Chalmers University of Technology, +46-31-772 2665,<a href="mailto:%20johan.eliasson@chalmers.se"> johan.eliasson@chalmers.se </a></div> <div><br /></div> </div>Fri, 01 Dec 2017 08:00:00 +0100http://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Collaboration-between-universities-strengthens-transport-research.aspxhttp://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Collaboration-between-universities-strengthens-transport-research.aspxCollaboration between universities strengthens transport research<p><b>​Transport and logistics research will benefit from extended collaboration between Chalmers and University of Gothenburg, according to Michael Browne. He is the new profile coordinator of Transport Efficiency and Customer Adapted Logistics within Chalmers Area of Advance Transport.</b></p>​“Research that contributes to transport system improvements to enable efficient and long-term sustainable transport and customer adapted logistics is very important and is something that should be addressed by researchers from different disciplines”, says Michael Browne. <br /><br />With a background from University of Westminster in London, Michael Browne is full professor in logistics and urban freight at University of Gothenburg since 2015. During the past 10-15 years his research has increasingly focused on urban freight and logistics.<br /><br />“Most of my research has considered the interaction between public policies and business decisions”, he says. “I am particularly interested in the way that research can influence public policy and organizational behavior.”<br /><br />As profile coordinator Michael Browne wants to play a part in continuing and extending the collaboration between University of Gothenburg and Chalmers building on the work of Dan Andersson, previous profile coordinator. He points out that there are already many areas where the two universities collaborate very well, and takes autonomous transport as an example of a field where technology, engineering and social sciences benefit from working together.<br /><br />“The transition to future transport provides many challenges and is an opportunity for researchers to work together on providing insights and potential solutions”, he says. “Combining our expertise in fields including psychology, geography, urban form, technology developments and logistics opens many possibilities.” <br /><br />Sinisa Krajnovic, Director of Area of Advance Transport, welcomes the strengthened connection between the universities. <br /><br />“Chalmers and University of Gothenburg need to increase their cooperation in the field of transport in order to meet the interdisciplinary challenges of society and industry. My hope is that Professor Browne will help us to cross borders between two universities and that this will lead to more joint projects and activities.”<br /><br /><em>Text and photo: Emilia Lundgren</em><br /><br />Tue, 28 Nov 2017 00:00:00 +0100http://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/The-biography-of-a-street-a-step-towards-a-more-sustainable-city.aspxhttp://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/The-biography-of-a-street-a-step-towards-a-more-sustainable-city.aspxThe biography of a street – a step towards a more sustainable city<p><b>You walk down Linnégatan in Gothenburg. Pick up your phone, open an app and the history of the street unfolds. Chalmers researcher Martin Emanuel hopes that this vision soon will become reality and that it will increase the will for change for a more sustainable urban environment.</b></p><div>​Historical knowledge can motivate people to change and make it easier for us to accept changes that will lead to a more sustainable society. Martin Emanuel, researcher at Technology Management and Economics at Chalmers, is convinced.</div> <h4 class="chalmersElement-H4">A rich picture of the street’s development</h4> <div>Through his research, Martin Emanuel wants to paint a rich and nuanced picture of the changes that a street has undergone during one hundred years – the biography of the street. Currently, he studies Linnégatan in central Gothenburg. Quantitative data such as traffic bills and apartment prices are collected, as are photographs from the archives of the Museum of Gothenburg and historical material concerning political decisions and urban construction processes. Together the different sources will map the development of the street.</div> <div><br /></div> <div>“As a historian, I can convey a sense of how the street has evolved. This can give insight that more sustainable city traffic solutions have existed than the ones we see today, and raise some thoughts that things could look different.”</div> <h4 class="chalmersElement-H4"><img src="/sv/styrkeomraden/transport/nyheter/PublishingImages/Arkivbild_GoteborgsStadsmuseum_250px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Digital platform next step</h4> <div>In the next step, the researchers want to connect the material to a digital platform.</div> <div><br /></div> <div>“Possibly an app where you can walk around the city and see how the streets once looked, and how they have changed in terms of character and traffic situation. By making the material available to both decision makers and people in general, we can put questions about sustainable urban mobility in a relevant and tangible context.”</div> <h4 class="chalmersElement-H4">Increase the will for change</h4> <div>When changes in city traffic infrastructure are planned, factors like changes in flow and traffic safety are evaluated. If a broader evaluation is made, that also includes historical insight, the actions and changes made today can be put in a longer time perspective. This will provide a wider basis for decision makers and planners, and can increase the acceptance and willingness to change of people in general, believes Martin Emanuel.</div> <div><br /></div> <div>“Such knowledge can make it easier to argue for changes, such as reduced car traffic. As we all know, car traffic has not dominated our cities historically.”</div> <div> </div> <div><strong>FACTS</strong></div> <div><strong>TO WRITE THE BIOGRAPHY OF A STREET</strong><br /><strong></strong></div> <div>The researchers collect three types of material:</div> <ul><li>Quantitative data such as traffic bills and apartment prices. These tell who could afford to live on the street and give a picture in figures of what the traffic looked like. </li> <li>Traditional historical sources of political decision-making, as well as urban and traffic planning. This material tells, for example, if the street has been widened, whether a bike path or a tram line has been abolished. These sources can also show how other changes, such as a shopping mall opening nearby, may change the character of the street and who moves there. </li> <li>Photographs can show how people actually used the city space, as opposed to plans that tell the imagined future use of a street. By studying photographs, one can also capture details that city and traffic planners did not think about, such as how people bring their goods from the store and home. What did they put on the carrier, how did they carry their things, did the pedestrians stay on the sidewalk?</li></ul> <div> </div> <div><strong>About the project</strong></div> <div>The pre-study &quot;Mixed methods for the Biography of a Street&quot; is funded by Chalmers Area of Advance Transport, as part of the area’s focus on the transition to future transport systems.

This means that it is still relevant to improve our internal combustion engines. One way to do this can be to encapsulate the engine. Blago Minovski presents in his Ph.D. thesis </div> <div>&quot;<em>Engine Encapsulation for Increased Fuel Efficiency of Road Vehicles</em>&quot; a method for calculating and predicting fuel savings in combustion engines through engine encapsulation design. </div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">- The computational efficiency of the method allows quick simulations that can be performed early in the vehicle design stages </span>in<span style="background-color:initial"> order to find the most beneficial encapsulating solution, says Blago Minovski </span></div> <div><span style="background-color:initial"><br /></span></div> <div>All internal combustion engines contain engine oil, which lubricates their parts during operation. Like many other fluids, engine oil becomes thicker at low temperatures. This also leads to a significant increase of the unwanted engine friction and makes the engine consume more fuel when cold. Thermal engine encapsulation is a combination of shells, mounted around the engine, that insulate it from the cold environment and keep it warm for a long time after we turn it off. This way it is more likely that the engine will be warm and efficient next time we start it. </div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">To design an engine encapsulation is a complex engineering task, which requires knowledge of the energy transport through the entire powertrain of the vehicle.

This is central for the correct prediction of the potential benefits from encapsulating the engine.</span></div> <div><span style="background-color:initial"> </span></div> <div>- Every gram of fuel that we can avoid burning for transportation reduces our environmental footprint.

The one who finds the smartest method to quickly verify a system becomes highly sought after. Carl-Johan Seger is one of those people.</b></p>​ <br />In 1995, Carl-Johan Seger received a phone call with an offer that would change the direction of his research career at the University of British Columbia. He had only a few days earlier taken up a professor's appointment with so-called tenure, a meriting position.<br />&quot;I started my new position in June 1995 and in September I resigned,&quot; says Carl-Johan Seger, laughing at the memory.<br /><br />The phone call came from the American semiconductor company Intel, who was in great need of his skills.<br />&quot;There was a crisis at Intel. They had just rolled out a new generation of Pentium processors when a serious error in the construction was discovered. The error had escaped Intel's very extensive verification procedures. The final bill landed somewhere in the neighbourhood of 475 million dollar&quot;, he says.<br /><br />The problem was that the traditional verification method did not allow testing of all conceivable values, it could simply not be done within the time frame, even though very extensive verification was carried out.<br /><br /><strong>Mathematical tools for verification</strong><br />Carl-Johan Seger's research is on formal methods, i.e., mathematical tools for analysis and verification of systems. Very useful for verifying hardware – in this case silicon circuits. The tools that Carl-Johan Seger worked with in his research could offer the solution to the precise problems that Intel suffered.<br /><br />&quot;With formal methods, we developed a verification tool that was not only more reliable, we could also perform the verification faster.&quot;<br /><br />As a result, Carl-Johan Seger introduced early formal verification in the development process at Intel. <br />&quot;Early formal verification is extremely important for achieving good results. It is only after we verify that we can know for sure, and can draw conclusions from the work. It is usually said that we learn by our mistakes, and I couldn’t agree more.&quot;<br /><br />At Intel, he created the Forte Formal Verification System, based on his previous research, and the same verification system is still used today, over 20 years later.<br />&quot;If you buy a computer today with an Intel processor, large parts of the processor are verified by this method.&quot;<br /><br /><strong>Return to academia</strong><br />He stayed at Intel for 22 years, and during that time he has published his research with great impact.<br />&quot;It has been fun working in industry, but there is not much long-term research done. In 2006-2007, I was given the opportunity to be a visiting researcher at Oxford&quot;, he says. <br /><br />Perhaps that is where the thoughts of returning to academia took shape? So, when Intel last year announced staff cuts, and launched a retirement package, he took the offer.<br />&quot;Intel's offer turned to those who with x number of years in the company, added with one's own age, summed to the number 75 or higher. And it included me with a 3-month margin.&quot;<br /><br />Carl-Johan Seger is pleased with his choice to return to academia and Chalmers, and the mood is on top during the interview. We wonder, of course, how he experiences the transition.<br />&quot;It's a big change, I cannot say it's neither better nor worse, but on the other hand – it takes a lot of effort and renewal and it makes me feel younger.&quot;<br /><br /><strong>Important part of autonomous systems</strong><br />Carl-Johan Seger is recruited as part of Chalmers activities in the Wallenberg project WASP – <a href="/en/areas-of-advance/ict/research/automated-society/wasp/Pages/default.aspx">Wallenberg Autonomous Systems and Software Program</a>. An important trend along with the development of autonomous systems is the decreasing gaps between hardware and software, we are seeing much more of programmable hardware. There are two very big benefits to doing so – increased performance and reduced energy consumption.<br /><br />&quot;When a large number of sensors are introduced to enable an autonomous system, and all sensors are sending their data to a central processor, it becomes inefficient and slow. Through programmable hardware, or FPGA, Field-Programmable Gate Array, we can introduce more intelligence closer to the sensors&quot;, says Carl-Johan Seger.<br /><br />FPGA are circuits in which the function of the circuit is determined by software. It provides flexibility, you do not necessarily need to re-design your hardware to introduce new functionality – just rolling out new instructions is enough. But there's a big challenge, it gets a lot more difficult to design and verify.<br />&quot;Look at cars for example, they contain many computer-powered features, and it's crucial that the systems respond quickly, never fail and are secured. This is what we are testing using formal methods&quot;, says Carl-Johan Seger. <br /><br />So, what does Carl-Johan Seger think about the future of self-driving vehicles out of a safety perspective? He says that there are several layers of technology in the vehicles – all are not critical systems.<br />&quot;There is a core in the systems that we need to find solutions for, in order for the self-driving vehicles to succeed. The future is about robust technology, but it's also about working out the regulations and what the consequences are if anything goes wrong. The market will determine how big risks that are reasonable to take. If the cost of errors becomes too large then we will not see any self-driving vehicles on the roads.&quot;<br /><br />Carl-Johan Seger points out that autonomous systems are not just about vehicles. We will see all sorts of new services, inspections, deliveries, window cleaning, and a host of applications in industry.<br />&quot;The development of autonomous systems leads to an increasing need to do right from the start – and thus it gets more and more important with verification. It is simply faster and less of a business risk to do it right the first time.&quot;<br /><br /><strong>Back at Chalmers</strong><br />Carl-Johan Seger is now recruited to Chalmers as Professor of Computer Science. Which means he is back at Chalmers where he started his studies in 1981, after nearly 34 years in Canada, the United States and Britain.<br />&quot;I don’t say I'm moving <em>back </em>to Sweden. I've been away for so long, so I say I'm moving to Sweden. It actually makes it a little easier for me.&quot;<br /><br />The first task at Chalmers is to build a verification system. Intel has proprietary ownership of the Forte system, so Carl-Johan Seger could not bring it to Chalmers for further research.<br />&quot;My wife usually says Forte is my fourth child, and maybe there is something to it. I have spent at least as many hours with Forte as with my three children.&quot;<br /><br />However, he has the old system to build on, the one he developed during his time as a researcher before leaving for Intel.<br />&quot;Now we are rebuilding, and this time, of course, it will go much faster because we already know the target.&quot;<br /><br /><br />Contact details: Carl-Johan Seger, <a href="mailto:secarl@chalmers.se">secarl@chalmers.se</a><br /><br /><em>Text: Malin Ulfvarson</em><br /><em>Photo: Anneli Andersson</em>Tue, 17 Oct 2017 09:00:00 +0200http://www.chalmers.se/en/departments/tme/news/Pages/Electric-cars-can-become-more-eco-friendly-through-life-cycle-assessment.aspxhttp://www.chalmers.se/en/departments/tme/news/Pages/Electric-cars-can-become-more-eco-friendly-through-life-cycle-assessment.aspxElectric cars can become more eco-friendly through life cycle assessment<p><b>​It is time to stop discussing whether electric cars are good or bad.

She will be replacing Mats Rydehell the 1 October 2017.</b></p>Maria Grahn is today a part of the profile area management for Sustainable Vehicle Technologies - one of six profile areas within Chalmers Energy Area of Advance.<br /><br />– It is with great excitement that I look forward to leading the Energy Area of Advance, says Maria Grahn. A global shift in the energy system aiming at lower emission of greenhouse gas is a key element in reaching the ambitious climate goals. Sweden aims at being one of the first welfare nations in the world boasting zero net emission of greenhouse gas. This means that there are huge energy related societal challenges for the Area of Advance to take on and collaboration is a key term. <br /><br />Maria was recently acknowledged for her research collaboration with Karin Andersson, focusing on the future of the shipping industry. They received the 2017 Areas of Advance Award.<br /><br />Maria Grahn's research at the department of Space, Earth and Environment is within the area of energy systems analysis, focusing on fuels for transport, global energy systems modeling, cost-effective use of biomass, global warming and carbon dioxide reductions. Maria is also interested in the global car fleet, the role of Electrofuels (fuels produced from carbon dioxide and water with the help of electricity) and in future fuels for the shipping industry. <br />Mon, 25 Sep 2017 12:00:00 +0200http://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/One-billion-to-be-invested-in-electric-mobility.aspxhttp://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/One-billion-to-be-invested-in-electric-mobility.aspxOne billion to be invested in electric mobility<p><b>​The Swedish government has decided to invest one billion kronor in the transition to an electrified transport sector. An important part of the initiative is a test bed in Gothenburg. Research institute Rise and Chalmers University of Technology will jointly build and own the facility.</b></p>​Mikael Damberg, Minister for Enterprise and Innovation, presented the initiative, which also includes biogas development, at a press conference at Lindholmen in Gothenburg on 5 September. A number of representatives from Volvo Group, Scania, Volvo Cars and Cevt (China Euro Vehicle Technology) participated together with Ann-Sofie Hermansson, Chairman of Gothenburg City Council, Pia Sandvik CEO of Risa, as well as Stefan Bengtsson, President and CEO of Chalmers University of Technology.<br /><br />“One third of the carbon dioxide emissions comes from the transport sector. To reduce emissions nationwide, the transport sector will have to go through a change”, says Mikael Damberg.<br /><br />The total investment is one billion kronor until 2023. The automotive industry is expected to contribute equivalent funding. In 2018, 180 million kronor will be invested in the test bed. Electrified gearboxes and drive shafts for different types of vehicles, component, drivetrain and full vehicle testing for hybrid and electric vehicles, charging, smart energy management, cloud computing and “Big data” usage – these are examples of research and testing areas for which the facility is to be equipped.<br /><br />Pia Sandvik, CEO of Rise, welcomes the initiative.<br /><br />“We will build a test bed with great innovation content”, she says.<br /><br />For Chalmers University of Technology, the initiative is of great importance for the quality of both research and education.<br /><br />“A facility of this kind will strengthen our ability to be at the forefront of knowledge in the transition to a fossil-free transport sector, and to promote the supply of competence to the industry in many ways”, says Stefan Bengtsson, President and CEO of Chalmers University of Technology.<br /><br />Henrik Svenningstorp has led Rise’s investigation of how a test bed for electric mobility could look and be financed. He will be heavily involved in the future work on building the test bed.<br /><br />“A strong research focus is important”, he says. “The test bed should not be for long-term testing only.”<br /><br />Fri, 15 Sep 2017 15:00:00 +0200http://www.chalmers.se/en/departments/m2/news/Pages/Piloting-Automated-Driving-on-European-Roads.aspxhttp://www.chalmers.se/en/departments/m2/news/Pages/Piloting-Automated-Driving-on-European-Roads.aspxPiloting Automated Driving on European Roads<p><b>​The Accident Prevention group in the division Vehicle Safety just started a big project on automation.

Chalmers is part of a two-year project that brings together industry and academia to develop a common global standard for future vehicle communication.</b></p>​“It's about using telecommunications to increase traffic safety and transport efficiency through connected and collaborative systems”, says Professor Erik Ström, Head of Communication and Antenna Systems at the Department of Electrical Engineering. “Today's wireless mobile system is not powerful enough to be used for vehicle communication, where safety always must be put first.”<br /><br />For traffic safety applications, very high demands are imposed on the reliability of the data being transmitted. In some cases, more than 99.999 percent of the transmitted information must also be delivered to the recipient.<br /><br />“In addition to the demands of high reliability, it is also crucial that data communication is fast and not delayed”, he continues. “In order to be traffic-safe, transmission times have to be as short as 5 milliseconds in certain use cases. This is very challenging.”<img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Projektet%20som%20sätter%20standarden%20för%205G%20i%20fordon/Erik_Strom_200x280px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><strong>Creates consensus among competitors</strong><br />In the project, competitors like Ericsson, Nokia and Huawei side by side, along with vehicle manufacturers like Volvo Cars and PSA, work out the common prerequisites for the 5G system and a global standard for vehicle communication.<br /><br />The work is about creating consensus and to agree on matters that need to be standardized. The telecom industry requires a common system platform to start from, when the manufacturers in the next step separately develop their products for the market.<br /><br />&quot;I am very pleased that we at Chalmers are taking part in setting the standard”, says Erik Ström. “It is an important and highly sought-after network to participate in, including both industry and other universities. We contribute, among other things, with knowledge from our fundamental research on positioning and wireless systems. In total, we expect the project to involve 46 month´s work for our researchers.”<br /><br />A part of the project is about vulnerable road users, such as pedestrians and cyclists. When the 5G technology is available in each person's mobile phone, data collection for example about position, direction and speed could be used to further enhance traffic safety in different situations.<br /><br />The project started in June 2017, and Chalmers made the first part-delivery in early September. By mid-2019, selected technology components will be demonstrated and project results incorporated into the 5G standard. The overall goal of 5GCAR is that vehicles connected with 5G technology will be out on the roads from 2020.<br /><br /><strong>Renewed confidence</strong><br />&quot;We are very pleased to, once more, been given the confidence to use our research in the development of technology that enables 5G in vehicles&quot;, says Erik Ström. “For us, this is the second project within 5GPPP.
