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%

Knorr-Bremse Group

│14

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

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
