Sensor Vision and Collision Warning Systems 2000-01-C001

Due to an earlier analysis of the interrelation between collisions and advanced driver reaction a significant number of accidents could be avoided through timely threat recognition and appropriate maneuvers for collision avoidance. This may be achieved either by suitable warning to the driver or by automatic support to longitudinal or lateral control of the vehicle. A precondition for the registration of the dangerous situation is the incorporation of appropriate sensors. This leads to an surround sensor vision system accompanied by a matched human machine interface.

Many vehicles readily offer ultrasonic reversing aids as add-on systems. Furthermore, long-range radar systems for adaptive cruise control are now coming on the market. New sensor technologies, such as short-range radar and video, which are currently under development, open up a plurality of novel functions thus enhancing driving safety and comfort. As a first step, functions for driver warning or information, e.g., lane departure warning, distance warning, are being introduced. In a second step, functions which intervene with vehicle dynamics through brake, steering and acceleration, will open up new perspectives for collision mitigation and collision avoidance.
