Abstract: The electric vehicle driven by the in-wheel motor has the advantages of simple structure, high efficiency and easy control, and it has broad development prospects. Electronic differential control based on the structure of the electric vehicle chassis driven by the in-wheel motor can improve the power performance, manoeuvrability and safety of the vehicle. However, this technology also has some technical difficulties. How to overcome these difficulties is significant in this technology. This paper analyses the electronic differential control technology of an electric vehicle driven by in-wheel motor in various automobile companies and universities, and summarises the current control strategies in related fields at home and abroad. The electronic differential control technology is explained.

Keywords: in-wheel motor; electric vehicle; electronic differential technology; control strategy; speed-based control; torque-based control; slip ratio-based control; integrated control.
