The invention provides a motor torque control method and device, equipment and a storage medium. The method comprises the steps that a first torque demand value is determined according to the accelerator opening degree and the vehicle speed; determining a target torque limit value of the driving motor at the current rotating speed; determining a second torque demand value according to a first magnitude relationship between the first torque demand value and a target torque limit value; determining a motor power demand value according to the second torque demand value and the current rotating speed of the motor; according to the engine power of the vehicle at the last moment, the current rotating speed of the engine, the power-up change rate and the power-down change rate, the power-up change amount and the power-down change amount of the engine are calculated; determining a final power demand value of the motor according to a second magnitude relationship among the power demand value of the motor, the first calculation result and the second calculation result; and calculating a final torque demand value of the driving motor according to the final power demand value of the motor and the current rotating speed of the motor. The power battery demand can be reduced, and the service life and reliability of the battery are improved.
