摘要
为了给自适应前照灯系统(Adaptive Front-Lighting System,AFS)提供一个控制算法验证平台,开发了一套基于汽车驾驶模拟器的AFS半实物硬件仿真平台。在该仿真平台中,PC机采集驾驶模拟器的档位、油门、离合、刹车、方向盘等驾驶信息,由车辆动力学模型模拟实际车辆行为,采用AFS控制模型计算车灯转角控制量,并发送至电机驱动模块进而控制车灯转动,同时将车灯转角信息反馈至PC机。实验表明,该系统能实时记录和显示AFS工作过程中的多种参数,便于进行实验观察和数据分析,从而为AFS系统的控制算法提供一个检验和修正的平台。
To provide a platform for control algorithm of AFS（Adaptive Front-Lighting System）, a semi-physical simulation platform for AFS based on vehicle driving simulator is presented. On the simulation platform, the signal of gear, throttle pedal, clutch pedal, brake pedal and steering wheel of vehicle driving simulator is sampled by PC, and with which the vehicle dynamics model is introduced to simulate the vehicle behavior. Then, the angle of the car front light should be rotated and calculated with the AFS control model, and is later sent to the motor driving model. Next, the actual turning angle of front light is returned to PC. The experiments show that with the semi-physical simulation platform, many parameters can be recorded and displayed, and it helps to make experiment observation and data analysis. It provides a convenient testing platform for control algorithm of AFS.
