The invention discloses a cooling control method of a motor control system, a storage medium and a vehicle. The motor control system comprises a motor and a motor controller, and the method comprises the steps that the temperature of the environment where the motor control system is located, the temperature of the motor and the temperature of the motor controller are obtained, and motor consumption power is obtained; according to the environment temperature, the motor temperature, the motor controller temperature and the motor consumption power, the target rotating speed of the water pump and the target PWM wave of the fan are determined; and controlling the water pump to work at the target rotating speed, and controlling the fan to work at the target PWM wave so as to cool the motor and the motor controller. The environment temperature and the motor consumption power are considered while the motor temperature and the motor controller temperature are considered, the rotating speed of the water pump and the PWM value of the fan are controlled according to the environment temperature, the motor temperature, the motor controller temperature and the motor consumption power, and the temperature change rate of the motor and the motor controller is maintained at the preset value. Energy consumption of the fan and the water pump is as low as possible.
