The invention discloses a power supply switching system and method, electronic equipment, a readable storage medium and a vehicle, and relates to the technical field of vehicle power supply, and the method comprises the steps that a main power supply sends a first output signal to a first control module; when the first control module detects that the voltage of the first output signal is normal, the first control module converts the voltage value of the first output signal into a power supply voltage value of a low-voltage-domain circuit of the vehicle, obtains a second output signal and supplies power to the low-voltage-domain circuit, and when the first control module detects that the voltage is abnormal, the first control module stops sending a state signal to the second control module; the standby power supply sends a third output signal to the second control module; the second control module converts the voltage value of the third output signal into a power supply voltage value under the condition that the state signal is not received within a preset time period, obtains a fourth output signal and supplies power to the low-voltage domain circuit, so that the main and standby power supplies are adopted for supplying power; the problem that in the prior art, a vehicle-mounted system and an advanced driving assistance system are abnormal due to a fixed power supply fault is solved.

    本申请公开了一种电源的切换系统、方法、电子设备、可读存储介质及车辆,涉及车辆供电技术领域,包括:主电源向第一控制模块发送第一输出信号;第一控制模块在检测到第一输出信号的电压正常的情况下,将第一输出信号的电压值转化为车辆的低压域电路的供电电压值,获得第二输出信号并向低压域电路供电,在检测到电压异常的情况下,停止向第二控制模块发送状态信号;备用电源向第二控制模块发送第三输出信号;第二控制模块在预设时长内未接收到状态信号的情况下,将第三输出信号的电压值转化为供电电压值,获得第四输出信号并向低压域电路供电,以实现采用主备电源供电,解决了在先技术中因固定电源故障引起车载系统、高级驾驶辅助系统异常的问题。
