Patent ID: 8024093

Claim:
An apparatus for adjusting an optical axis of a headlight on a motorcycle, said apparatus comprising: a vehicle body attitude detector, said vehicle body attitude detector includes a front vehicle height sensor and a rear vehicle height sensor for detecting vehicle heights of front and rear portions of a body of the motorcycle, respectively; a kickstand position detector for detecting a position of at least one of a center kickstand and a side kickstand of the motorcycle; and a controller for receiving input from said detectors, and for adjusting an optical axis of the headlight in an upward or downward direction in accordance with input received from the vehicle body attitude detector; wherein when the kickstand position detector detects that one of the center kickstand and the side kickstand is in a deployed position thereof, the controller is operated to adjust the optical axis of the headlight to be oriented in a previously set initial direction, regardless of the detection output received from the vehicle body attitude detector, each of the vehicle heights of the front and rear portions of the motorcycle body is represented by a compression or decompression amount of a suspension of a corresponding one of front and rear wheels of the motorcycle, the optical axis is moved downward when the controller determines that the rear portion of the motorcycle body is shifted downward, the optical axis is moved upward when the controller determines that the entire motorcycle body is shifted downward, and the initial direction is set to a direction lower than a normal running direction.
