Abstract

The invention relates to an electronic speed differential control system of an electric wheel drive vehicle, which comprises a controller, a motor controller of each hub motor, a rotation angle sensor, an electronic accelerating pedal and a rotation speed sensor, wherein the rotation angle sensor is used for measuring the rotation angles of a steering wheel; the electronic accelerating pedal can output opening values; and the rotation speed sensor is used for measuring the actual rotation speed of the hub motor. The signal output ends of the electronic accelerating pedal, the rotation speed sensor and the rotation angle sensor are respectively connected with the signal input ends of the controllers. The controller is communicated and connected with the controller of each hub motor. Each controller comprises a first-stage following control module and a second-stage following control module. The invention can be used for reasonably controlling the electronic differential speed of each driving motor.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a steering control system for an electric vehicle, in particular to a steering control system for an electric wheel drive vehicle. Background technique [0002] Electric vehicles have the advantages of energy saving and environmental protection, and are a trend in the development of current automotive technology. The electric wheel drive vehicle is a new type of electric vehicle. The drive motor is mounted on the wheel directly or through a reduction mechanism to form an electric wheel. The layout of the electric wheels is very flexible, and can be used as two front wheels, two rear wheels or four wheels of the electric vehicle, correspondingly making the electric vehicle a front-wheel drive, rear-wheel drive or four-wheel drive vehicle. [0003] Compared with internal combustion engine vehicles and single-motor drive electric vehicles, electric wheel drive vehicles have unique technical ...
