Title: Optical axis compensating method of vehicle lamps
Inventor: OOMORI YASUJI
IPC: B60Q1/115
Filed: 1983-06-02
Abstract: PURPOSE:To prevent a vehicle with a ground level adjusting means from giving any glare to a counter driver regardless of any adjustment of an optical axis performed according to ground level and loading condition by controlling the lamps of the vehicle to have the angle of the optical axis compensated according to adjustment of the ground level. CONSTITUTION:When a vehicle runs at a low speed, the head lamp 2 has the optical axis L0. When the vehicle runs at a high speed following the low speed, the head lamp 2 is put into the condition C1 of the forward tilted attitude by a ground level adjusting means. The attitude angle control signal S1 is sent to the signal generator 8 of a control means 9 and when the signal is zero, the generator 8 of a control means 9 and when the signal is zero, the generator 8 develops a head lamp control signal S2 to make an actuator 7 lower a rod 6, whereby compensating the direction of the optical axis L0 from that of the optical axis L1. The ground level adjusting duration, if spent long due to loading condition, will not have an effect that the direction of the optical axis is turned upper than that of L0. On the contrary, when the driving speed is turned into a low speed, the signal S2 is generated instantaneously with the input of the signal S1, whereby surely preventing glare against the counter drive car.
