Abstract
A headlamp control system for a motor vehicle includes a wave transmitting and wave receiving device for detecting objects. The headlamp control system determines the state of the vehicle headlamps based upon objects detected by the wave transmitting and wave receiving device. The wave transmitting and wave receiving device can be a radar, an optical radar, ultrasonic, or the like. An optical sensor can be used to detect ambient light or other vehicles.
