自适应前照灯运动学建模及系统开发

Kinematics Modeling and System Development of Adaptive Front-lighting System

根据自适应前照灯系统(AFS)的功能要求,推导了车辆参数(车速、转向盘转角和车身仰俯角)与车灯光轴沿水平和垂直两个方向的偏转角度之间的关系,建立了自适应前照灯系统的运动学模型。在此基础上开发了自适应前照灯系统硬件结构,并在实验室建立了该系统的试验平台,对所提出的运动学模型进行了验证,效果良好。

According to the functional requirements of adaptive front-lighting system （AFS）, the relationships between the yaw angle and pitch angle of light axis in AFS and vehiele parameters, including speed, steering wheel angle and pitch angle of vehicle body are derived, thus a kinematics model for AFS is set up. On this basis, the hardware structure of AFS is developed and a test rig is built in laboratory. Finally, the kinematics model of AFS is verified on the rig with good results achieved.
