Title:
LEVELING CONTROL DEVICE AND LAMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/058628
Kind Code:
A1
Abstract:
Provided is a head lamp including an actuator for adjusting an optical axis. A leveling control device (200) controls an actuator on the basis of output of a rear vehicle height sensor. A calculation unit (210) receives the output (SSNS) of the rear vehicle height sensor (120) and calculates an inclination of a vehicle body in a front-and-rear direction from a sensor value based on the output (SSNS). A relationship between the sensor value and an inclination angle (θ) is defined as a polygonal line in the calculation unit (210). The polygonal line can be corrected on the basis of information specific to the vehicle body to which the leveling control device (200) is mounted.
