<p><P>PROBLEM TO BE SOLVED: To provide an auto-leveling system for a vehicular lamp detecting a pitch angle of a vehicle body on an inclination passage such as a slope and attaining proper illumination. <P>SOLUTION: This vehicle includes: an acceleration part CA of the vehicle; and a vehicle body CS suspended on the acceleration part, and is constituted such that a lamp HL is arranged on the vehicle body CS and a lamp optical axis LA of the lamp HL can be leveling-controlled in a vertical direction. The vehicle includes: a first sensor S1 provided on the vehicle body CB and detecting an absolute pitch angle of the vehicle body; a second inclination sensor S2 provided on the acceleration part CA and detecting the absolute pitch angle of the acceleration part; and a leveling control device 1 for leveling-controlling the lamp optical axis LA based on the respective detection values of the first and second inclination sensors S1, S2. Even when the pitch angle of the acceleration part is varied and the pitch angle of the vehicle body is varied accordingly, a pitch angle of only the vehicle body relative to a road surface can be obtained and proper leveling control can be attained. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
