Abstract

The invention discloses a motor torque control method and device for a hybrid electric vehicle and a storage medium, and belongs to the technical field of vehicles. The method comprises the steps thata wheel edge drive torque value needed by the hybrid electric vehicle is obtained; according to the wheel edge drive torque value, the power loss sum of all motors in various distribution proportionsof the hybrid electric vehicle is calculated, and the hybrid electric vehicle comprises at least two motors; and the distribution proportion with the smallest power loss sum is selected for distributing torque for the all the motors of the hybrid electric vehicle. Since the distribution proportion determined by the method enables the power loss to the smallest, torque distribution reasonability is ensured, and power consumption waste is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for controlling motor torque of a hybrid electric vehicle, and a storage medium. Background technique [0002] Hybrid electric vehicle is a combination of engine and motor, which has the advantages of low fuel consumption, long driving mileage, relatively high technology maturity, etc., and can also meet my country's new National VI emission requirements. It is currently the first choice for the development of major automobile companies . [0003] At present, most hybrid vehicles adopt a single-motor hybrid structure. This structure increases fuel consumption in hybrid mode and lacks power in pure electric mode. Therefore, a hybrid system with a multi-motor structure appears. [0004] However, in a hybrid system with a multi-motor structure, there will be a problem of rationalization of torque control when multiple motors are driven at the same time. If th...
