ITS European Congress Glasgow: Fraunhofer ESK paves the way for safe autonomous driving
Driver assistance systems, such as for parking or automated distance control, are standard features in nearly all automobiles today. They simplify driving and increase safety. Before taking the next step to safe automated driving, vehicles must be capable of reliably sharing information. At the ITS European Congress on June 6-9 in Glasgow (exhibit booth D60), Fraunhofer ESK will be demonstrating how and with what technologies the communication between driver assistance systems can be validated.
One step towards connected, automated driving is the use of the so-called cooperative driver assistance systems, which provide improved traffic safety and efficiency. One possible application is the lane change assistant, which makes it easier to overtake other vehicles on the highway. Drivers are warned of con-cealed vehicles in the vicinity in real-time through car-to-car communication. This can help avoid accidents when changing lanes.
Apart from its own system data, the vehicle processes information and warnings from other vehicles and the traffic infrastructure, such as traffic lights. In order to ensure that such distributed information can be processed, researchers at Fraunhofer ESK have developed software frameworks for reliable development of cooperative driving functions. Reliability is validated through features such as continuous error analyses which immediately detect errors in the information flow during the development phase, thus allowing a quick analysis of the problem.
One step ahead: heterogeneous networking concepts
Existing cellular networks are not designed to handle large numbers of vehicles which are continuously sharing information with one another and the traffic infrastructure. Fraunhofer ESK scientists are conducting research into algorithms which detect the optimal path for sharing information between driver assistance systems in any situation. They exploit different communication technologies and increase reliability even when the vehicles are equipped with different communication systems. „We are already satisfying the future communication requirements for cooperative driver assistance systems“, says Josef Jiru, Group Manager for Automotive Connectivity at Fraunhofer ESK, with confidence.
