The invention relates to a switching circuit, a power supply control device and a vehicle. The switching circuit comprises a current detection module, a control module and a simulation diagnosis module. The current detection module is connected between the power supply input end and the power supply output end; the first output end of the current detection module is electrically connected with the input end of the control module; the second output end of the current detection module is electrically connected with the first input end of the simulation diagnosis module; the output end of the control module is electrically connected with the second input end of the simulation diagnosis module; the output end of the simulation diagnosis module is electrically connected with an external processor. Whether the switching circuit breaks down or not can be judged in time according to the output voltage, the fault type when the switching circuit breaks down is determined, a user is reminded in time, and the safety of the vehicle is improved.
