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

San Diego Project as an example of Sustainable Mobi lity – Can be realized on Current technological level.

� More intensive innovation is expected “outside” of the vehicle in order to control the traffic flow (either ad-hoc or region dependent)

� Targets:

– Better utilization of the road infrastructure, toll-road type of solutions

– Significant reduction of fuel consumption and emission

� Necessary technology:

�Electronic brake control

�Driver independent intervention into the steering

�Technology for lane keeping assistance

�Distance control

�GPS technology

�Vehicle-to-vehicle communication

�Unified vehicle control architecture and platform
