Headlight optical axis adjustment device

Abstract

The present invention aims to perform optical axis adjustment while a vehicle is stopped only in necessary situations and to avoid unnecessary adjustment, and to further enhance durability. A headlight optical axis adjustment device for adjusting an optical axis of a headlight based on a pitch angle of the vehicle includes an opened/closed state detection section for detecting an open/closed state of an open/close unit where the opened state is when a passenger gets on/out or when a baggage is being loaded/unloaded to and from the vehicle; and an optical axis adjustment permitting section for permitting optical axis adjustment of the headlight based on the pitch angle of the vehicle when the opened state of the open/close unit is detected by the opened/closed state detection section.

1 . A headlight optical axis adjustment device for adjusting an optical axis of a headlight based on a pitch angle of a vehicle; the headlight optical axis adjustment device comprising:
 an opened/closed state detection section for detecting an opened/closed state of an open/close unit where the opened state is when a passenger gets in/out or when a baggage is being loaded/unloaded to and from the vehicle; and   an optical axis setting section for prohibiting the optical axis adjustment of the headlight based on the pitch angle of the vehicle when the opened state of the open/close unit is detected by the opened/closed state detection section, and setting the optical axis of the headlight to a predetermined angle so as not to dazzle the drivers of oncoming vehicles and pedestrians.   
     
     
         2 . The headlight optical axis adjustment device according to  claim 1 , further comprising:
 a behavior detection section for detecting a behavior change of the vehicle necessary for calculating the pitch angle; wherein   the optical axis setting section sets the optical axis of the headlight to the predetermined angle so as not to dazzle the drivers of oncoming vehicles and the pedestrians when the opened state of the open/close unit is detected by the opened/closed state detection section, and a detection value of the behavior detection section is greater than a predetermined value.
