<P>PROBLEM TO BE SOLVED: To provide a technique to allow more efficient auto-leveling control in the auto-leveling control of the vehicular lamp that uses an acceleration sensor. <P>SOLUTION: A levelling ECU 100 includes: a receiving part 102 for receiving output values of an acceleration sensor 110; a control part 104 for deriving a variation in an inclination angle of a vehicle 300 based on the output values of the acceleration sensor 110 and generating a control signal for instructing an optical axis adjustment of a vehicle lamp; and a transmitting part 106 for transmitting the control signal to a levelling actuator 226. The control part 104 detects an error factor of the output values occurring in the acceleration sensor 110 based on the output values of the acceleration sensor 110 to correct an optical axis position of the vehicle lamp. <P>COPYRIGHT: (C)2012,JPO&INPIT |
