Abstract

The invention discloses a driving control system of an electric automobile with rear wheels driven by independent motors. The driving control system comprises a driving controller and is characterized in that electric signal output ends of an left front wheel rotating speed sensor, a right front wheel rotating speed sensor, a left rear wheel rotating speed sensor, a right rear wheel rotating speed sensor, a Hall position sensor of a left driving motor, a Hall position sensor of a right driving motor, an accelerator pedal position sensor, a steering wheel rotating angle sensor and a braking sensor are connected with a corresponding signal input end of the driving controller respectively, power lines of the left rear wheel driving motor and the right rear wheel driving motor are connected with a corresponding output interface of the controller, and the driving controller is further provided with a CAN (controller area network) interface for communicating with the outside. The driving control system of the electric automobile with the rear wheels driven by the independent motors is suitable for driving control of the electric automobile with front wheels serving as steering wheels and the rear wheels driven by the independent motors, accurate in driving control algorithm, good in control effect and capable of improving transmission efficiency, reducing abrasion caused by slippage of tires, realizing handling stability of the electric automobile and guaranteeing safe traveling of the electric automobile.

Description

technical field

[0001] The invention relates to an electric vehicle drive control system. Background technique

[0002] With the further shortage of world oil resources and strict environmental protection requirements, all countries in the world are focusing on energy-saving and environmentally friendly electric vehicles, and electric vehicles have developed rapidly. At present, the power transmission system of electric vehicles mainly has two layout forms: centralized and distributed. The centralized layout is to replace the position of the traditional car engine with the electric motor, and the power still passes through the clutch, transmission, universal transmission, differential and drive axle. output to the drive wheels. The distributed arrangement is to install the driving motor near the driving wheel, and the output power of the motor is directly transmitted to the driving wheel, or transmitted to the driving wheel after being decelerated by the reduction mecha...
