Combining real world tests and simulation
Autonomous emergency brake (AEB) systems are a model demonstration of the importance of regulatory requirements for autonomous vehicles. Imagine the situation of a pedestrian appearing from between parked cars and wanting to step into the road. The prediction of what happens next depends on huge variations of different parameters, such as the probability of detection, the vehicle’s speed, the pedestrian’s speed, the road traction, the distance between car and pedestrian, and much more. This variety of situations and parameters is instantly calculated by an oncoming vehicle.
Consequently, a huge number of scenarios must be considered in order to safely assess and approve future driver assistance systems. TÜV SÜD experts estimate that 100 million safety scenarios will have to be tested before one single fully autonomous driving function can be approved. In order to consider every possible situation, TÜV SÜD experts and their partners in the PEGASUS project have been following a hybrid approach, in which the safety tests are largely conducted in virtual simulations and selected representative scenarios are performed on test grounds or in the field. This combination of virtual and real-world tests should cover the whole spectrum of driverless functions and ensure their safety.
IT security moves into focus
Safety measures in autonomous cars will be expanded to communicate and interact beyond the vehicle itself. This includes car-to-car and car-to-infrastructure communication, which can take place over a variety of communication protocols (LTE, 5G, radio etc.).
This level of connectivity and the variety of the communication interfaces increase the risk of hacker attacks on vehicle electronic and information systems, which could consequently affect road safety and the data privacy of road users. Cyber security and privacy are just as important as the safety of the vehicle’s autonomous driving functions.
For both system and IT security, therefore, TÜV SÜD experts are developing new and reliable methods and standards for connected vehicles. TÜV SÜD can rely on its reliable and international base of IT expertise built up over the years as a successful service provider for IT security for various applications, including industrial facilities, energy suppliers and railways.
