<p><P>PROBLEM TO BE SOLVED: To provide an auto-leveling system resistant against noise and capable of performing control of high accuracy. <P>SOLUTION: The auto-leveling system comprises an auto-leveling controller 10 and a levelizer 20. The levelizer has a drive motor 21 for driving a headlight of a vehicle, and a control circuit 24 for correcting the irradiation direction of the headlight by driving the drive motor 21. The auto-leveling controller has a control circuit 11 which determines whether or not the irradiation direction must be corrected from a state of the vehicle, and transmits the correction signal for commanding the correction to the control circuit 24 if the irradiation direction must be corrected. A digital signal input unit (a digital input port Rx) is provided on the control circuit 24 so that the signal to be transmitted/received between the control circuit 11 and the control circuit 24 can be transmitted/received as the digital signal. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
