ABSTRACT:
A vehicular cornering lamp system which reduces spark noise generated by a motor thereof, reduces wear of parts such as the brushes and commutator of the motor, and improves the rate of use of the power voltage of the system and thereby generates sufficient torque to rotate the motor. An illumination direction control circuit generates voltages to be applied to the two terminals of the motor according to differences between the output voltage of a lamp illumination angle sensor and the output voltage of a steering sensor. The illumination direction control circuit applies the center voltage of a supply battery voltage to the two terminals of the motor when the voltage difference is zero, and as the voltage difference increases, changes the voltages applied to the motor terminals in a direction such that a difference between the applied voltages increases, and, as the voltage difference decreases, changes the voltages applied to the motor terminals in a direction such that the difference between the applied voltages decreases.
