The invention provides a power supply mode switching control method. The method comprises the following steps: when a firmware upgrading request is received, judging whether a vehicle condition meetsa preset first switching condition or not; if the first switching condition is met, sending a first switching instruction to a power supply control unit, wherein the first switching instruction is aninstruction for notifying the power supply control unit to switch the power supply mode from an OFF mode to an ON mode so as to start firmware upgrading; when an upgrading ending request is received,judging whether the vehicle condition meets a preset second switching condition or not; and if the second switching condition is met, sending a second switching instruction to the power supply controlunit, wherein the second switching instruction is an instruction for notifying the power supply control unit to switch the power supply mode from the ON mode to the OFF mode so as to end firmware upgrading. The power-on and power-off moments can be accurately obtained, the accuracy of power mode switching in the firmware upgrading process of all the electronic control units of the vehicle is improved, the success rate of firmware upgrading of the automobile is increased, and the downtime phenomenon is avoided.

    本发明提供了一种电源模式切换控制方法,所述方法包括:当接收到固件升级请求时,判断车辆条件是否满足预设的第一切换条件;若满足第一切换条件,则向电源控制单元发送第一切换指令,其中,第一切换指令为通知电源控制单元将电源模式从OFF模式切换为ON模式以开始固件升级的指令;当接收到结束升级请求时,判断车辆条件是否满足预设的第二切换条件;若满足第二切换条件,则向电源控制单元发送第二切换指令,其中,第二切换指令为通知电源控制单元将电源模式从ON模式切换为OFF模式以结束固件升级的指令。本发明可准确获知上电和下电时刻,提高了汽车各个电子控制单元固件升级过程中电源模式切换的准确性,提高车辆固件升级的成功率,避免宕机现象。
