    • A projecting direction control system for a vehicle headlamp comprises a wheel-speed detecting means for detecting left and right wheel speeds and a posture decision means for calculating centrifugal force from the left and right wheel speeds obtained by the wheel-speed detecting means, difference between the wheel speeds, and characteristic information of the vehicle including vehicle width and vehicle weight so as to apprehend a rolling condition. The rolling condition can be recognized accurately from the direction and strength of the centrifugal force by calculating the centrifugal force during turning motion.
    • 用于车辆前照灯的投影方向控制系统包括用于检测左右车轮速度的车轮速度检测装置和用于根据车轮速度检测装置获得的左右车轮速度来计算离心力的姿势判定装置, 车轮速度和车辆的特性信息,包括车辆宽度和车辆重量,以便理解滚动条件。 通过计算转动运动中的离心力,可以从离心力的方向和强度准确地识别滚动条件。
