The invention provides a vehicle control method and device and a relay control system. The method comprises the steps that a relay of a vehicle is controlled to be closed according to the state of the vehicle and/or the control requirement of a driver; detecting the state of the relay; under the condition that the state of the relay is the normal state, normal control logic is executed; and when the state of the relay is the abnormal state, the relay is controlled to be disconnected in a delayed manner. In the scheme, the relay is directly controlled to be locked in the closed state firstly, under the condition that the state of the relay is detected to be the normal state, the vehicle can execute normal control logic, under the condition that the state of the relay is detected to be the abnormal state, the relay is controlled to be still kept in the closed state, and then the relay is controlled to be disconnected in a delayed mode. In this way, the relay and the motor can be kept electrically connected all the time, the vehicle cannot lose power suddenly, enough power can be provided for controlling safe parking of the vehicle, and then the safety of the vehicle in the running process is guaranteed.

    本申请提供了一种车辆的控制方法、控制装置和继电器控制系统。该方法包括:根据车辆的状态,和/或,驾驶人员的控制需求控制车辆的继电器闭合;检测继电器的状态;在继电器的状态为正常状态的情况下,执行正常控制逻辑;在继电器的状态为异常状态的情况下,控制继电器延时断开。该方案中,直接控制继电器先锁定在闭合状态,在检测到继电器的状态为正常状态的情况下,车辆可以执行正常控制逻辑,在检测到继电器的状态为异常状态的情况下,控制继电器依然保持在闭合状态,再控制继电器延时断开,这样继电器和电机可以一直保持电连接,车辆不会突然失去动力,可以有足够的动力控制车辆安全停车,进而保证了车辆行驶过程中的安全。
