摘要：
In a vehicle cornering lamp system, a control signal having a pulse width corresponding to a steering angle is periodically produced, and the amount of position shift between the actual direction of illumination of the headlamps and the target direction of illumination determined from the steering angle is detected according to the control signal thus produced. An electric motor is driven to change the direction of illumination of the headlamps so that the amount of position shift becomes zero, that is, the direction of illumination of the headlamps is linearly changed with the electric motor while following the steering angle.
