The controller controls the devices in accordance with a traveling condition of a vehicle. When an abnormality of the swivel device, the leveling device or the signal transmission paths is detected, the controller forcedly switches the light distribution to the sub-beam. The light distribution is also switched to the sub-beam when the swivel device or the leveling device stops at the dazzling position, thereby preventing the dazzling.

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.

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.

Abstract: An adaptive front-lighting system includes lamp deflection angle controlling means having a steering angle sensor for detecting a steering direction of a vehicle and supplying a signal and controlling a deflection angle of a lamp based on sensor outputs from the steering angle sensor. The lamp deflection angle controlling means includes an arithmetic control means for calculating a time series moving average of the output from the steering angle sensor. Averaging the output from the steering angle sensor on the time axis in the arithmetic circuit means enables to obtain outputs having smaller step widths than step widths of the outputs from the steering angle sensor, and controlling the deflection angle of the lamp based on the output enables to control the deflection angle of the lamp with the minute step widths.

Abstract: An adaptive front-lighting system includes a lamp deflection angle controlling means for controlling a deflection angle of an auxiliary lamp that is attached to a main lamp corresponding to a traveling state of a vehicle. The system is provided with vehicle halting state detecting means for detecting a halted state in which the vehicle is halted or traveling at a very low speed, and illumination controlling means for turning off or dimming an auxiliary lamp when the halted state is continued for more than a prescribed time period. When the vehicle is halted with the auxiliary lamp deflected, and the halted state is continued for more than the prescribed time period, the auxiliary lamp is turned off or dimmed, and thus other cars and pedestrians are prevented from being dazzled by the auxiliary lamp, and the trailing car may be prevented from having a sense of insecurity.

Abstract: A vehicle lighting apparatus includes abnormality detecting means for detecting abnormality in the AFS of the vehicle lighting apparatus, and means for adjusting optical axis of the lamp in the vertical direction for setting the angle of the optical axis of the lamp downward in the vertical direction in comparison with the reference angle upon receipt of abnormality-detected signal from the abnormality detecting means. When the vehicle lighting apparatus lapsed into malfunction, by tilting the optical axis of the lamp in the deflected state downward in the vertical direction, the lamp is prevented from dazzling oncoming cars even when the lamp is in the deflected state toward the oncoming cars, thereby realizing failsafe which is preferable in terms of traffic safety.
