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.

Dependent claims

A vehicle headlamp system comprising:

headlamps for forwardly emitting beams from a vehicle;
beam control means for controlling the beams emitted from said headlamps;
road configuration detection means for detecting a road configuration ahead of the vehicle;
and
turning-angle detection means for detecting the turning angle of the vehicle,
wherein said beam control means is provided with a road-configuration-corresponding mode in which beam control is performed according to the results detected by said road configuration detection means, and a corresponding-turning-angle mode in which beam control is performed according to the results detected by said turning-angle detection means, and
further wherein one of said road-configuration-corresponding mode and said corresponding-turning-angle mode is selected in response to the vehicle speed.
