Park Assist(mainly still standing objects) E.g. Adaptive Cruise Control (partially very complex traffic scenarios with moving objects) Simple modification of test conditions /scenarios like Parking spaces Braking vehicles in front /back Safety while testing ADaS like emergency braking (no danger/accidents Reproducibility of tests of different complexities Early Validation available(MIL, SIL) Along the whole development(HIL, VIL Virtual Test Driving Technology 2013- Session ADAS 15112013|5 PC AUTO MOTIVE ADAS Application examples Challenges and Solutions /Application examples ACC/EBS HMI LDW/ LKAS Parking Assistance Autonomous Driving Active/Passive Safety Virtual Test Driving Technology 2013- Session ADAS 15112013|7 PC AuT。 MOTIVE ADAS Application examples ACC, Emergency Braking System a.
