The invention relates to the technical field of unmanned vehicle control, and provides an intelligent trailer control system and method for an unmanned vehicle, and the method comprises the following steps: judging the validity of a trailer instruction according to an obtained switching signal, and transmitting a trailer state and a whole vehicle state to a CAN bus; in the trailer instruction effective state, safety control is conducted on a driving system and a heat dissipation system of the vehicle; and acquiring a motor rotating speed signal, a trailer mode signal and a maximum allowable trailer rotating speed signal sent by the motor controller, determining a maximum trailer speed signal and a trailer mode signal, and sending the signals to an instrument for display. According to the method, when the vehicle is towed, whether the vehicle can be towed or not is judged according to the signal, the effectiveness of the vehicle towing instruction is judged, then the driving system and the heat dissipation system are controlled after the vehicle enters the vehicle towing mode, and the vehicle towing process and the state of whether the vehicle can be towed or not are automatically displayed in the instrument; therefore, the safety and the reliability of the intelligent driving vehicle during towing are improved.

    本公开涉及无人驾驶车辆控制技术领域,提出了一种无人驾驶车辆智能拖车控制系统及方法,包括如下步骤:根据获取的开关信号,判断拖车指令的有效性,同时向CAN总线发出拖车状态和整车状态;在拖车指令有效状态下,对车辆的驱动系统和散热系统进行安全控制;获取电机控制器发出电机转速、拖车模式与最高允许拖车转速信号,确定最高拖车车速和拖车模式信号,并发送至仪表进行显示。本公开中,车辆进行拖车时,首先根据信号判断是否能够进行拖车,拖车指令的有效性进行判断,然后在进入拖车模式后对驱动系统和散热系统进行控制,将拖车过程以及是否能够进行拖车的状态在仪表中进行自动显示,以提高智能驾驶车辆拖车时的安全性和可靠性。
