The invention relates to a vehicle drive-by-wire chassis, in particular to a chassis domain network wireless communication steering and braking system and a vehicle, the chassis domain network wireless communication steering and braking system comprises a steering wheel, a control unit, a wireless local area network unit, a steering execution mechanism and a braking execution mechanism, the steering wheel is connected with a corner information acquisition element and a grip strength information acquisition element; the control unit is fixed to a steering wheel and used for obtaining steering wheel turning angle information, steering wheel grip strength information and vehicle body posture information in a whole vehicle CAN network, and target steering torque and target braking torque of wheels are obtained through real-time calculation. The wireless local area network unit is used for realizing communication between the control unit and the steering execution mechanism as well as the brake execution mechanism; the steering execution mechanism is used for receiving the target steering torque of the control unit and controlling wheels to steer; the brake executing mechanism is used for receiving the target brake torque of the control unit and controlling wheel braking. The integrated level is high, the steering and braking response speed is high, and the response and operation time of a driver during vehicle danger avoiding is effectively shortened.

    本发明涉及车辆线控底盘,具体涉及一种底盘域网络无线通讯转向制动系统及车辆,包括方向盘、控制单元、无线局域网单元、转向执行机构和制动执行机构,方向盘连接有转角信息采集元件和握力信息采集元件;控制单元固定于方向盘上,用于获取方向盘转角信息、方向盘握力信息以及整车CAN网络中车身姿态信息,实时计算得到车轮的目标转向力矩和目标制动力矩;无线局域网单元用于实现控制单元与转向执行机构和制动执行机构的通讯;转向执行机构用于接收控制单元的目标转向力矩,控制车轮转向;制动执行机构用于接收控制单元的目标制动力矩,控制车轮制动。其集成度较高,转向和制动响应速度快,有效缩短车辆避险时驾驶员的反应、操作时间。
