14 Driver Assistance Systems Atomatic Emergency Brake System ACC-Sensor Based Possible vehicle path Intervention time Principle functions - Early warning of driver (e.g. by short brake application) - Reduction of collision energy by full braking at a time where collision is unavoidable for driver Potential: Reduction of collision energy by 50% 14

15 Driver Assistance Systems - Automatic Emergency Brake System Sensor Fusion Based Possible vehicle path Intervention time Usage of ACC-Radar in combination with camera: Principle functions as before, but - Reaction on stationary objects (can be identified as relevant objects) - Identification of object size and -orientation (earlier detection of relevant situations) Higher mitigation potential + 15

16 Driver Assistance Systems - Video-Systems Road Sign Recognition Lane Detection Road Sign Assistance Speed Limit Assistance Intersection Assistance Lane Departure Warning Lane Keeping Support Object Relevance Decision NightVision high beam visibility in low beam situations increased safety Object Detection Collision Warning ACC Full Speed Range Low Speed Following Recognition of cutting traffic 16 16

17 Autonomous Emergency Brake System Sensor data/features: Multi-stage intervention First: warning to the driver (acoustical and/or haptical by brake jerk) If driver doesn't react on warning => braking with limited deceleration If driver reacts: improved brake assistant (target braking) If no reaction and collision unavoidable => full braking Driver can override system at any time (e.g. by accelerator or steering) Benefit in CVs higher than in passenger cars due to lower vehicle dynamics and -speed AEBS pass a development process tailored to safety relevance 17
