Modeling and simulation of traction control of Hybrid Electric Vehicle

Slipping drive wheels can provide little lateral force, thus when drive wheels are slipping, the front wheel drive vehicles will lose turning ability, while the rear wheel drive vehicles will spin. Compared to the conventional vehicles, HEVs are more easily to slip when driving on slippery road, since the electric motor can provide large drive torque under low speeds. In this paper, the dynamic modeling of a HEV which consists of engine modeling, ISG modeling and vehicle dynamics is realized and a traction control strategy based on the said modeling is proposed, and effectiveness of the traction control strategy is verified by simulation. The present traction control strategy consists of the PID control to the ISG and the logic gate control to the engine.
