Abstract
Beams from headlamps are controlled by a beam control ECU. The beam control ECU has a road-configuration-corresponding mode and a corresponding-turning-angle mode. In the road-configuration-corresponding mode, beam control is performed according to the detected results of a road configuration ahead of a vehicle. In the corresponding-turning-angle mode, beam control is performed according the detected results of the turning angle of the vehicle. One of these modes is selected in response to the vehicle speed. Thus, the beam emitting direction is prevented from being inadvertently changed-irrespective of the rise and fall of vehicle speed-through the actuation of a direction indicator or a steering operation.
