The invention provides a vehicle-mounted braking execution circuit driving method and device and a medium, and relates to the technical field of braking systems. Connecting a power supply of a vehicle-mounted brake execution motor to a vehicle-mounted brake execution circuit; judging whether the power supply is reversely connected according to the power supply reverse connection protection module; if the power supply is not reversely connected, according to the main control unit, whether the vehicle-mounted brake execution motor receives the PWM waveform is judged; if yes, judging whether the PWM waveform is a forward rotation signal or not according to the main control unit, and generating a waveform signal judgment result; and on the basis of the waveform signal judgment result, a vehicle-mounted brake execution motor is controlled according to an H-bridge motor driving module, and state early warning is conducted on the vehicle-mounted brake execution motor according to a current temperature sampling module. The vehicle-mounted brake circuit solves the technical problem that an existing vehicle-mounted brake circuit lacks a power supply reverse connection protection mechanism and an effective early warning mechanism, and the failure risk of a brake system exists, and the stability, safety and response speed of the brake system are improved.
