ABSTRACT:
A back warning system and method for a vehicle are provided. The system includes an electronic system and a plurality of sensor units. When the vehicle is backed, the electronic system transmits a sensor drive message and then generates a warning based on a received warning level. The sensor units are driven when receiving the sensor drive message, sense a distance from a rear obstacle, and transmit a warning level corresponding to the sensed distance to the electronic system.
