Driving assisting device for car, has rear sensor measuring distance separating vehicle from its follower vehicle, and controller receiving signals from front and rear sensors and controlling actuator with setpoint function of signals

摘要

The device has a controller (3) receiving a signal generated by a front sensor (2), and generating a control signal for controlling an actuator (4) to stop a vehicle (1), during detecting a collision risk between the vehicle and an obstacle i.e. vehicle (12) preceding the vehicle (1). A rear sensor (5) measures the distance separating the vehicle (1) from a vehicle (15) following the vehicle (1). The controller receives a signal generated by the rear sensor and controls the actuator with a setpoint function of the signals delivered by the front and rear sensors. An independent claim is also included for an emergency braking method of a motor vehicle.
