A Study on Control System for Four-Wheels Independent Driving and Steering Electric Vehicle

The structure and principle of four-wheels independent driving and steering (4WIS-4WID) electric vehicle are presented firstly, and on this basis the structure of network control system base on CAN bus is built. Kinematics and dynamics models of typical steering modes (such as all wheel steering, front (rear) wheel steering, parallel steering, zero-radius steering) are built, and the control strategy is presented. The experimental results show that the control system structure and control algorithm are effective.
