ABSTRACT:
A method and system for automatic control of the distance between a vehicle to be controlled and a lead vehicle. The vehicle to be controlled is equipped with a distance-control device having a distance sensor and a brake device with a brake pedal. The distance-control device controls the speed of the controlled vehicle by delivering a brake-actuating signal to the brake device in such a way that the distance between the vehicles does not become shorter than a predefined distance, the distance-control device also generating a warning signal to the driver if the distance becomes shorter than the predefined distance. The distance-control device changes the brake pedal characteristic in such a way that the brake pedal travel required for injection of increased brake pressure is minimized if a criterion that indicates a danger of collision is present.
