The invention provides a vehicle control method and system, and the method comprises the steps: issuing a first state signal through a CAN network, employing the first state signal as a control instruction, instructing each load control subsystem to close a corresponding load, starting the upgrade after the load is closed, and issuing a power-off instruction signal after the upgrade is completed, and controlling the power-off of a vehicle. Therefore, the power consumption of the system activity on the storage battery is ended. According to the vehicle control method and system provided by the invention, the power consumption load of the electric device is turned off before upgrading, so that the standby power consumption of the electric device of the whole vehicle in the upgrading process is reduced, the consumption of the electric quantity of the storage battery in the upgrading process is reduced, the risk that the electric quantity of the storage battery is too low is reduced, and the starting reliability after the vehicle is upgraded is improved; the use reliability of a vehicle equipped with an OTA function is improved.
本发明提供一种车辆控制方法和控制系统,其在确认升级时,通过CAN网络发布第一状态信号,以第一状态信号作为控制指令,指示各负载控制子系统关闭对应的负载,并在负载关闭后,开始升级,在升级完成后,发布下电指令信号,控制车辆下电,以结束系统活动对蓄电池的耗电。本发明提供的车辆控制方法和控制系统通过在升级前,关闭用电器件的耗电负载,降低升级过程中整车用电器件的待机耗电,降低升级过程对蓄电池电量的消耗,降低蓄电池电量过低风险,提高了车辆升级后的启动可靠性,提高了搭载有OTA功能的车辆的使用可靠性。
