Abstract
This invention provides a vehicle front lamp light distribution control system wherein only when the vehicle velocity is less than a predetermined value and the blinker is operated, the beam angle of a light distribution means on a side corresponding to an indication direction of the blinker is changed to a maximum extent in the indication direction.
Claims6
A vehicle front lamp light distribution control system, comprising:
- a light distribution means provided on each of front lamps on the right and left sides of a front face of a vehicle for changing beam angles in the right/left direction;
- a steering wheel condition detecting means for detecting a steering direction and a steering angle of the steering wheel;
- a blinker condition detecting means for detecting an operating condition and an indication direction of the blinker;
- and
- a control means for changing an beam angle of the light distribution means on a side corresponding to the steering direction of the steering wheel in a steering direction of the steering wheel by an amount corresponding to a steering angle thereof by inputting signals from the vehicle velocity detecting means and the blinker condition detecting means, wherein said control means changes the beam angle of the light distribution means on the side corresponding to the indication direction of the blinker in the indication direction to a maximum extent only when the vehicle velocity is lower than a predetermined value and the blinker is operated.
