Today´s cars are full of electronics and software. But what will happen if there is a serious bug in the software? In a new research project at Halmstad University, deviations in the behaviour of vehicle software will be analysed and evaluated, so that our roads can be as safe as possible.
Mohammad Mousavi, Professor in Computer Systems at Halmstad University, is in charge of the new research project called AUTO-CAAS. AUTO-CAAS is funded by the Swedish Knowledge Foundation and is a collaborative project between Halmstad University and Swedish industry. The research goal is an automated method, a warning system, which can be used when testing software in car manufacturing.
– We will analyse deviation in software based on the AUTOSAR standard, which is used in most new cars. Deviations in AUTOSAR can lead to software errors that, in a worst case scenario, can cause serious security flaws and accidents. Safe software is important in all cars, but it will be crucial in the future autonomous vehicles, says Mohammad Mousavi.
Halmstad University has recruited Dr. Wojciech Mostowski from University of Twente in the Netherlands, to strengthen the research team of model-based testing and verification. Mostowski comes from Poland and received his PhD at Chalmers in Sweden. For the past ten years, Mostowski has focused on research about verification of software and information security.
The research will be done together with two companies in Gothenburg, namely, Quviq AB and Arccore AB. Quviq has developed a model of AUTOSAR in order to detect deviations in software. Researchers at Halmstad University can analyse these deviations. Arccore delivers AUTOSAR software to car manufacturers, such as Volvo, and to subcontractors.
– Existing testing techniques for software are barely sufficient for cars produced today. Future cars will be even more complicated and require new testing techniques. Quviq focuses on research within this area, and the collaboration with Halmstad University is an important component in securing the quality of future software in cars, says Thomas Arts, CTO at Quviq AB.
– More and more embedded electronics in vehicles, and the rapid growth of software, leads to an increase in the system’s complexity. This demands improved testing techniques. Our clients have to be able to guarantee the safety of their vehicle system solutions. Our joint research project is an important step towards new and efficient testing techniques, says Michael Svenstam, Sales Manager for Arccore AB.
