The invention relates to a vehicle control unit integrated with a TCU gear shifting motor control circuit, which is characterized in that a sensor power supply circuit unit supplies power to a sensor unit, and the sensor unit acquires the current gear position of a gear shifting motor and the rotating speed of a gearbox gear in real time and outputs a corresponding voltage sensing signal; the microprocessor unit acquires a voltage sensing signal through the sensor signal acquisition circuit unit; when the microprocessor unit judges that gear shifting is needed, the microprocessor unit controls connection and disconnection of an MOS tube in the motor drive circuit unit through the MOS tube pre-drive circuit unit according to the voltage sensing signal, the motor drive circuit unit drives the gear shifting motor, gear selection and gear advancing and retreating are conducted, and the gear shifting function of the gearbox is achieved. The vehicle control unit is integrated with the TCU function, and the integrated vehicle control unit is used for controlling the whole vehicle and the gear shifting mechanism, so that the hardware and structure cost is reduced, the whole vehicle control logic is simplified, the logic complexity of the whole vehicle control software is reduced, and the processing speed is increased.
