Improved electronic differential control equipment for four-wheel drive and four-wheel steering of electric automobile

Abstract

The invention discloses improved electronic differential control equipment for four-wheel drive and four-wheel steering of an electric automobile. The equipment comprises a connecting module, a main control box, a hub, a detection module, a control module and a driving module for driving wheels to rotate, the main control box is connected with the hub through the connecting module, the control module comprises an electronic differential controller and a hub motor controller which are arranged in the main control box, the detection module comprises an angle sensor, a rotating speed sensor, a pressure sensor and a temperature sensor, the angle sensor, the rotating speed sensor, the pressure sensor and the temperature sensor are all arranged on the hub, the angle sensor, the rotating speed sensor, the pressure sensor and the temperature sensor are all coupled with the electronic differential controller, and the electronic differential controller is coupled with the driving module. The operation stability of linear driving of the automobile is facilitated, the possibility of sideslip, tipping and the like is reduced, the turning radius is reduced, the rapidity and flexibility of turning response are improved, and the stability during high-speed steering is ensured.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to an improved electronic differential speed control device for four-wheel drive and four-wheel steering of an electric vehicle. Background technique [0002] Conventional means of transportation are powered by conventional fuel gasoline, diesel, etc., but it will cause environmental pollution, and with the consumption of resources, it will form an energy crisis, which is not conducive to the concept of sustainable development of green environmental protection. Under this background, the development of electric vehicles Quickly, it is powered by the on-board power supply, which has less impact on the environment than traditional cars, and it uses motors to drive the wheels, which makes it easier to realize intelligent vehicle control. [0003] The rise of in-wheel motor technology provides greater development space for electric vehicles, omitting a large number of transmission ...
