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
