Abstract
A rear monitor system for an automotive vehicle comprises a sensor secured to a vehicle door located on one side of the vehicle and adapted to be operated by a vehicle occupant when leaving the vehicle, the sensor generating a signal indicating that the occupant is going to leave the vehicle. A control unit is responsive to the signal from the sensor for transmitting radiant energy in a rearward direction to detect a reflection from an object approaching the vehicle from behind at a speed higher than a predetermined value. Further provided is a safety device which is responsive to the detected reflection for preventing the vehicle occupant from opening the door.
