Abstract

The invention provides a motor torque control method, device, storage medium and vehicle. By obtaining the required torque and the actual torque of the motor, if the required torque is in the opposite direction to the actual torque, the actual torque of the motor is controlled to approach 0, and when the actual torque of the motor reaches 0, the motor is controlled The actual torque approaches the demand torque. Thereby avoiding the direct switching of the torque of the motor between positive torque and negative torque, eliminating the abnormal sound of the transmission shaft of the motor, improving driving comfort, and further improving user experience.

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 ...
