Irradiation direction control apparatus for vehicular lamp
First Claim
1. An irradiation direction control apparatus for a vehicular lamp, comprising:
- vehicle state detection means for detecting a state of a vehicle;
drive means for directing irradiation light of a lamp toward a desired direction; and
compensation calculation means for performing a compensation calculation to keep said irradiation light of said lamp to a predetermined direction in accordance with a signal from said vehicle state detection means and sending a compensation signal to said drive means,whereby at a time of lighting said lamp or during lighting of said lamp, said compensation calculation means performs said compensation calculation to keep said irradiation light of said lamp to said predetermined direction in accordance with said signal from said vehicle state detection means and sends said compensation signal based on a calculation result to said drive means to drive said lamp or components thereof,whereas at a time of deactivating said lamp or during deactivation of said lamp and with a power source of said vehicle in operation or during running of said vehicle, said compensation calculation means performs only said compensation calculation to keep said irradiation light of said lamp to said predetermined direction in accordance with said signal from said vehicle state detection means and does not send said compensation signal to said drive means.

Abstract
An irradiation direction control apparatus for a vehicular lamp including: a vehicle state detection device for detecting a state of a vehicle; a drive device for directing irradiation light of a lamp toward a desired direction; and a compensation calculation device for performing a compensation calculation to keep the irradiation light of the lamp to a predetermined direction in accordance with a signal from the vehicle state detection device and sending a compensation signal to the drive device, whereby at the time of lighting the lamp or during lighting of the lamp, the compensation calculation device performs the compensation calculation to keep the irradiation light of the lamp to the predetermined direction in accordance with the signal from the vehicle state detection device and sends the compensation signal based on a calculation result to the drive device to drive the lamp or components thereof, whereas at the time of deactivating the lamp or during deactivation of the lamp and with a power source of the vehicle in operation or during running of the vehicle, the compensation calculation device performs only the compensation calculation to keep the irradiation light of the lamp to the predetermined direction in accordance with the signal from the vehicle state detection device and does not send the compensation signal to the drive device.
