Abstract

The invention discloses a motor torque control method, device and system. The method includes the steps that the inclination angle of a slope where a vehicle is located currently is obtained; according to the inclination angle, the peak torque corresponding to the inclination angle is determined; and a motor of the vehicle is controlled to operate with the torque not larger than the torque of thepeak torque. The technical problem that electric energy is wasted in torque control schemes in the correlation techniques is solved.

Description

technical field [0001] The present invention relates to the field of electric vehicles, in particular to a method, device and system for controlling motor torque. Background technique [0002] Nowadays, as new energy electric vehicles become a new direction of future development, more and more people are beginning to pay attention to new energy vehicles. Compared with new energy vehicles, traditional fuel vehicle technology is relatively mature. In real life, you will find that when a fuel car is on a slope, the fuel injection volume of the car will automatically increase or decrease, thereby increasing or decreasing the output power. This is because most of today's fuel vehicles adopt multi-point electronic injection or direct injection technology, and the electronic control unit (Electronic Control Unit, referred to as ECU) automatically detects the operating conditions of the vehicle and the engine, thereby automatically changing the injection mode. The size of the oil ...
