Abstract

The invention provides a motor torque control method, a device, storage medium, and a vehicle. A required torque and an actual torque of a motor can be acquired, and when the required torque is opposite from the actual torque, the actual torque of the motor can be moved towards 0, and when the actual torque of the motor reaches 0, the actual torque of the motor is moved towards the required torque. The torque of the motor is prevented from being directly switched between the positive torque and the negative torqued, and the abnormal noise of the transmission shaft of the motor can be eliminated, and therefore driving comfort can be improved, and user experience can be improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a motor torque control method, device, storage medium and vehicle. Background technique [0002] Hybrid electric vehicle is a kind of new energy vehicle that has emerged in recent years. Because of its advantages of energy saving, environmental protection and low emission, it has attracted great attention from the automotive industry. The motor is an important power source of the hybrid electric vehicle, and the performance and working characteristics of the electric motor seriously affect the performance of the hybrid electric vehicle. Torque is one of the basic parameters of the motor. It is an important research direction to improve the performance of hybrid electric vehicles by controlling the torque to realize the control of the motor, and then to improve the performance of the vehicle. [0003] In the prior art, by obtaining the current output torque of the motor and the target ...
