The embodiment of the invention discloses a circuit detection method, a switch safety circuit, a device, a vehicle and a storage medium. The method is applied to a switch safety circuit, the switch safety circuit comprises a vehicle body controller and a power-off switch circuit, the vehicle body controller is connected with the power-off switch circuit in series, and the method comprises the steps that when a power-off switch is pressed down, first voltage and second voltage output by the power-off switch circuit are obtained through the vehicle body controller, the first voltage is the voltage, collected by a first switch detection interface in the vehicle body controller, of a first key switch interface in the power-off switch circuit, and the second voltage is the voltage, collected by a second switch detection interface in the vehicle body controller, of a second key switch interface in the power-off switch circuit; and performing fault detection on the power-down switch based on the first voltage and the second voltage. According to the method, fault detection can be carried out on the power-down switch based on multiple paths of acquired switching voltages, and the detection failure rate is reduced.

    本申请实施例公开了一种电路检测方法、开关安全电路、装置、车辆及存储介质。应用于开关安全电路,开关安全电路包括车身控制器和下电开关电路,车身控制器与下电开关电路串联,所述方法包括:当下电开关被按下时,通过车身控制器获取下电开关电路输出的第一电压和第二电压,其中,第一电压为车身控制器中的第一开关检测接口采集的下电开关电路中的第一按键开关接口处的电压,第二电压为车身控制器中的第二开关检测接口采集的下电开关电路中的第二按键开关接口处的电压;基于第一电压和第二电压对下电开关进行故障检测。通过上述方法,可以基于多路采集的开关电压对下电开关进行故障检测,降低了检测失效率。
