The invention provides a power supply control circuit, a control method and an automobile. The power supply control circuit at least comprises a trigger circuit, a switching circuit, a self-locking circuit, a quick starting circuit, a first control circuit and a second control circuit. In the shutdown state, when the first control circuit receives an upgrading instruction, the self-locking circuit enables the switching circuit to be switched on, so that the first control circuit is switched on, and then system upgrading after flameout is achieved. The switch circuit in a sleep state and a conduction state detects an enable signal of the trigger circuit, the first control circuit sends the enable signal to the quick start circuit, and the quick start circuit controls the second control circuit to be conducted, so that the load unit enters a normal working state, and secondary ignition quick start within preset time is realized. According to the method, the complete shutdown of the vehicle machine in the shutdown state is realized, the quiescent current reaches 0mA, and meanwhile, the system upgrading after the flameout of the vehicle and the rapid starting of the second ignition within the preset time are supported.

    本申请提供了一种电源控制电路、控制方法及汽车。所述电源控制电路至少包括触发电路、开关电路、自锁电路、快速启动电路、第一控制电路和第二控制电路。在关机状态,第一控制电路接收到升级指令时,自锁电路使能令开关电路导通,以使第一控制电路导通,从而实现熄火后系统升级。在睡眠状态,处于导通状态的开关电路检测到触发电路的使能信号,第一控制电路发出使能信号至快速启动电路,快速启动电路控制第二控制电路导通,使负载单元进入正常工作状态,从而实现预设时间内第二次点火快速启动。所述方法实现了车机在关机状态时完全关机,静态电流达到0mA,同时支持汽车熄火后系统升级以及在预设时间内第二次点火快速启动。
