Abstract

The invention relates to the field of motor control and provides a motor output torque control method and device and an automobile and aims to solve the technical problem of failure in realization ofautomobile driving and braking through one pedal in the prior art. The motor output torque control method in an embodiment includes: determining a driving mode of the automobile; acquiring acceleratorpedal openness and motor rotating speed when the driving mode of the automobile is a single-pedal driving mode; determining a motor initial output torque according to the accelerator pedal openness and motor rotating speed; subjecting the motor initial output torque to torque limiting value processing to obtain a torque after torque limiting value processing, and outputting. The motor output torque control method and device and the automobile have the advantage that automobile driving or braking through one pedal namely the accelerator pedal is realized.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a motor output torque control method, device and automobile. Background technique [0002] When the car is running, if it is necessary to accelerate the car, it is necessary to step on the accelerator pedal of the car to control the output torque of the motor; when the car needs to decelerate, it is necessary to step on the brake pedal of the car to achieve braking. That is, in the prior art, two pedals are needed to brake or accelerate the car, and, due to the two-pedal driving mode, it often happens that the driver uses the accelerator pedal as the brake pedal to cause traffic accidents. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a motor output torque control method, device and automobile, so as to realize braking and driving of the automobile through one accelerator pedal. [0004] In order to ...
