Problems solved by technology

Since the establishment of the driving force has a process from small to large, when the driving force is not strong enough and the mechanical braking force is gone, the vehicle will first slide backwards and then move forward. This effect affects the user experience And there are certain security risks

Abstract

The invention provides a motor control method, a motor control device and a carrier. The motor control method is used for a carrier driven by a motor and comprises the steps of acquiring a carrier speed, a carrier driving signal and a carrier braking signal; and if the carrier speed is less than the preset value and the carrier driving signal and the carrier braking signal exist, commanding the motor to output a driving force according to the carrier driving signal when the carrier speed is less than the preset value. The motor control method, the motor control device and the carrier are simple, reliable, easy to implement, stable in operation and the like, and improved ramp starting experience can be provided.

Description

technical field [0001] The present application relates to the field of motor management strategies for vehicles. More specifically, the present application relates to a motor control method aimed at providing an improved hill start experience by changing the motor output strategy. The present application also relates to a motor control device intended to implement the above motor control method. The present application also relates to a vehicle comprising the above motor control device. Background technique [0002] In existing vehicles, the motor is usually used to drive the wheels of the vehicle, and the motor is controlled by the driver. For example, the driver's braking operation will cause the vehicle controller to generate an electronic braking control command, and the electronic braking control command will cause the motor to output a braking force to perform the braking operation, or directly cut off the power of the motor. The driver's operation of turning the fo...
