Method and device for controlling motor torque and automobile

Abstract

The invention provides a method and device for controlling motor torque and an automobile, and relates to the field of motor control. The problem that a motor cannot determine the unique target torque when an electronic stabilization system is started or not started in the prior art can be solved. The method for controlling the motor torque in the embodiment of the invention includes the steps that current output torque of the motor and target need torque of the motor are acquired; and the current output torque of the motor can be adjusted according to the target need torque of the motor, and the motor is controlled to achieve outputting according to the adjusted torque. According to the method and device for controlling the motor torque and the automobile, the motor torque can be controlled under the condition that the motor stabilization system is started or not started, and the safety traffic of the automobile can be guaranteed; and meanwhile, the effect that the jitter amplitude of the automobile is small in the torque switching process of the motor can be ensured, the automobile smoothness is good and the comfort level is high.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a motor torque control method, device and automobile. Background technique [0002] Cars are an indispensable means of transportation for people to live and travel. With the increase of the number of cars, the probability of traffic accidents is gradually increasing. [0003] In order to reduce the occurrence of traffic accidents, in the prior art, an electronic stability system (ESP) will be added to the vehicle. When the various parameters collected by the electronic stability system in real time determine that there is a potential safety hazard in the vehicle, the electronic stability system will actively monitor the vehicle. The motor intervenes to adjust the output parameters of the motor to ensure the safe driving of the car. [0004] The problem in the prior art is that when the electronic stability system is activated, the electronic stability system will output a target tor...

Problems solved by technology

[0004] The problem in the prior art is that when the electronic stability system is activated, the electronic stability system will output a target torque to the motor, and at the same time, the controller on the vehicle will also output a target torque to the motor according to the driver's intention. In this case, the motor will receive two target torques, and the motor cannot determine which target torque to adjust the output torque according to
