    • A vehicle lighting apparatus includes lamp deflection angle controlling means for controlling the change of a deflection angle of a lamp. The vehicle lighting apparatus further includes a reference angular position setting means for setting the deflection angle of the lamp to a predetermined reference angular position when a deflection angle detecting means for detecting the deflection angle of the lamp is broken down. When the deflection angle of the lamp cannot be detected in an adaptive front-lighting system (AFS), and thus the AFS lapsed into malfunction, the deflection angle of the lamp is fixed to a reference position obtained by rotating a motor for deflecting the lamp in one direction to the locked state, and from this locked state, rotating by the given amount in the reverse direction.
    • 车辆照明装置包括用于控制灯的偏转角的变化的灯偏转角控制装置。 车辆用照明装置还具有用于检测灯的偏转角的偏转角检测单元被分解的基准角位置设定单元,用于将灯的偏转角度设定为规定的基准角度位置。 当在自适应前照灯系统(AFS)中不能检测到灯的偏转角时,因此AFS失效,灯的偏转角度被固定在通过使用于使灯偏转的电动机旋转而获得的基准位置 在一个方向处于锁定状态,并且从该锁定状态以相反方向旋转给定量。

    • In a headlamp apparatus comprising a sub-CPU integrally provided on a headlamp for controlling an optical axis direction changing operation and a main CPU for sending out to the sub-control circuit a control signal for changing the direction of the optical axis, the sub-CPU comprises a power-on resetting circuit of a simple configuration comprising a capacitor and a resistor. When the main CPU detects an abnormality in the sub-CPU, a power supply is temporarily cut off by a power supply control means, and the sub-CPU is reset by a power-on resetting circuit. An abnormality triggered by a runaway of the sub-CPU can be resolved so that the sub-CPU can be restored to a normal condition as quickly as possible.
