Abstract
本发明公开了一种汽车的电子机械制动系统、一种轮边执行器和一种车辆，电子机械制动系统包括主控制器和四个轮边执行器，主控制器设置于车辆驾驶舱，适于接收整车外部信号并同时执行整车级的控制决策和轮边级的制动执行决策；四个轮边执行器分别设置于四个轮边，与主控制器通信连接，主控制器适于控制各个轮边执行器动作。轮边执行器包括设置于转轴外周的磁环和侧置的角度传感器。本发明利用主控制器实现轮边控制和上层控制合并，改善了轮边控制的工作环境，提升了信号质量和运行可靠性，显著降低了成本。同时，轮边执行器无需设置轮边控制的电路板，可以减小轴向尺寸；轮边执行器利用磁环实现电机角度信号的监测，可靠性高。
