Abstract: This paper proposes a novel traction control for a front-wheel drive in-wheel motor electric vehicle. The presented vehicle has advantages on high fuel efficiency and cost effectiveness. In order to achieve specific control performance, this study employed a high speed microcontroller as the vehicle's electronic control unit. The anti-skid function based on a reliable traction control kernel is embedded in the system, which can guarantee the steering safety in a slippery and dangerous situation. This study verifies that the traction control based on maximum torque regulation cannot only constrain the slip to improve the longitudinal friction force and lateral friction force, but also provide some information on tyre-road conditions, which can ensure the performance and the effectiveness of two-dimensional motion control. The numerical simulation and demonstration video reveal its effectiveness and feasibility.
