Problems solved by technology

[0003] However, at present, many electric vehicles do not involve the slope assist function of the chassis. In this way, once the braking force provided by the braking system of the electric vehicle cannot overcome the force of the vehicle sliding down the slope, the vehicle will slide down the slope under braking. phenomenon, which seriously affects the safety of electric vehicles

Abstract

The embodiments of the invention provide a motor torque control method and device as well as an electric automobile. The motor torque control method comprises the following steps of obtaining the current running state of the electric automobile; determining required target torque at the running state when the running state indicates that the electric automobile is at a down sliding state; and controlling the torque output by a motor of the electric automobile to be the target torque. The motor torque control method and device can reduce the down sliding condition happening to the electric automobile and facilitates the improvement of safety of the electric automobile.

Description

technical field [0001] The present application relates to the technical field of vehicle control, and more specifically relates to a motor torque control method and device and an electric vehicle. Background technique [0002] With the increasingly serious problems of energy crisis and environmental pollution, new energy vehicles have become a changing trend in the automotive industry. As a new energy vehicle, electric vehicles are widely used due to their advantages of high efficiency and energy saving. [0003] However, at present, many electric vehicles do not involve the slope assist function of the chassis. In this way, once the braking force provided by the braking system of the electric vehicle cannot overcome the force of the vehicle sliding down the slope, the vehicle will slide down the slope under braking. This phenomenon seriously affects the safety of electric vehicles. Contents of the invention [0004] In view of this, the present application provides a mo...
