The present invention provides a torque control method, device, and electric vehicle, which relate to the technical field of motor control. The method includes: obtaining the current torque demand of the electric vehicle; wherein, the current torque demand includes: vehicle stability torque demand, driving At least one of passenger torque demand, adaptive cruise torque demand, automatic parking torque demand and series recovery function torque demand; if the current torque demand includes at least two torque demands, then according to the at least two torque demands A torque control command is generated by comparing with the pre-stored torque response priority; according to the torque control command, the motor is controlled to output a corresponding torque. The scheme of the present invention simplifies the torque management strategy, clarifies the torque response priority, optimizes the torque chain structure of the whole vehicle, and improves the safety and comfort of the whole vehicle.
Description
technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a torque control method, device and electric vehicle. Background technique [0002] With the development of the automobile industry towards intelligence, safety, and integration, the torque interface is becoming more and more complex, including driver demand torque, intelligent demand torque, braking demand torque, vehicle stability demand torque, etc., resulting in confusion in torque control , there are current situations such as the torque is not easy to maintain, and problem location is difficult, which reduces the safety and comfort of the vehicle. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a torque control method, device and electric vehicle, so as to solve the problem in the prior art that the torque control is chaotic, which leads to a decrease in the safety and comfort of the vehicle.
