Abstract

The invention discloses a chassis driving system for a four-wheel drive electromobile and a control method of the chassis driving system. The chassis driving system comprises a car frame, wheels and a Macpherson independent suspension, wherein four corners of the car frame are connected with the wheels through the Macpherson independent suspension. The driving system is characterized by comprising a driving motor system and a motor transmission system; the driving motor system adopts sprung mass design, so as to improve the stability and riding comfort of the running electromobile; the driving motor system comprises driving motors corresponding to the four wheels, so that each wheel can rotate independently; under the control of a control system, power switching is very easy, and front wheel drive, rear wheel drive or four-wheel drive can be realized; as the rotational speeds of the wheels are controlled by the four motors independently, the rotational speeds of inner wheels and outer wheels can be controlled to meet a steering model during steering, reduce abrasion of tires, and prolong the service lives of the tires; the independent suspension can be used conveniently.

Description

technical field [0001] The invention relates to the field of design and manufacture of electric vehicles, in particular to a chassis drive system and control method of a four-wheel drive electric vehicle. Background technique [0002] At present, there are two common drive train schemes for electric vehicles - differential half shaft scheme (single motor) and multi-motor drive scheme (multi-motor). The differential half-shaft scheme is similar to the drive train layout method of traditional power vehicles, that is, the power is transmitted to the left and right half-shafts through the differential after deceleration and torque increase. The multi-motor drive scheme arranges multiple motors, and each wheel is driven by a single motor, and the on-board computer and motor control module control and coordinate the working conditions of different wheel motors. [0003] The differential half-shaft scheme is characterized by mature and simple technology and easy implementation; th...
