Automatic distance regulation system for road vehicles has distance sensor in front of each vehicle connected to programmed distance regulation circuit connected to control circuit and brake

摘要

The automatic distance regulation system (1) has a distance sensor (2) sending distance (d) and speed (v) signals to a programmed distance regulation circuit (4). This incorporates a collision risk assessment circuit (12) and is connected to brake control circuit (6). The brake control unit has an additional program unit (14) and is connected to the brake pedal and the brakes (8). The first step (20) of the computing process compares sensed vehicle distance and desired distance and calculates desired speed. Further steps (22,24) check that the distance is not below a given minimum value and that sufficient brake power is available.
