ABSTRACT:
A vehicle cornering headlamp system in which the direction of illumination of the headlamps of an automobile are made to follow the actual direction of movement of the vehicle, except that the direction of illumination is returned to the straight-ahead direction more quickly than it is moved away therefrom, thereby more accurately following the usual eye movement of the driver. For this purpose, a control signal is generated which has a pulse width indicative of the steering angle but which has a variation characteristic with respect to steering angle which is larger when the steering wheel is turned back towards the straight-ahead position than when the steering wheel is turned away from the straight-ahead position.
