A torque chain control architecture and dual-motor four-wheel drive electric vehicle

Abstract

The invention provides a torque chain control framework and a double-motor four-wheel drive electric automobile. The torque chain control framework comprises a torque obtaining module, a first torquelimiting module, a torque distribution module and a second torque limiting module, wherein the torque obtaining module is used for obtaining the demand torque of a driver, and sending to the first torque limiting module, and the first torque limiting module is used for limiting the demand torque to obtain a demand limiting torque; the demand limiting torque is sent to the torque distribution module, divided into a first front axle motor torque and a first back axle motor torque through the torque distribution module, and sent into the second torque limiting module; the second torque limiting module is used for limiting the first front axle motor torque and the first back axle motor torque according to the fault classes of the vehicle, the limited first front axle motor torque is sent to afront axle motor controller, and the limited back axle motor torque is sent to a back axle motor controller, so as to confine the torque chain control framework.

Description

technical field [0001] The invention relates to the field of power control of electric vehicles, in particular to a torque chain control framework and a dual-motor four-wheel drive electric vehicle. Background technique [0002] The increasing severity of energy issues and environmental issues has promoted the development of electric vehicles. With the advancement of electric vehicle technology, electric vehicles are becoming more and more popular. [0003] Currently common electric vehicles have three driving modes: front drive, rear drive and four-wheel drive, wherein four-wheel drive refers to the fact that the front axle and rear axle of the electric vehicle are respectively provided with drive motors. Four-wheel-drive electric vehicles are also called dual-motor four-wheel drive electric vehicles. Since dual-motor four-wheel drive electric vehicles are equipped with two drive motors, they have strong power and ability to get out of trouble, and can cope with relatively...
