Fuzzy Prediction Control Strategy for Hybrid Electric Vehicle of Energy Hybridization

A combination of different electric energy supply with different feature is designed for high acceleration and long distance and improves the whole system properties. Energy supply system with energy hybridization of high energy and high power requires an intelligent management system in order to control power. A fuzzy prediction control strategy of energy management system (EMS) was proposed based on a new forward-looking and causal structure model. This control strategy is mainly consisted of three controllers, including SOC prediction controller, recharge controller and power split controller. Simulation result shows that the driving range, the fuel economy and the vehicle efficiency of fuzzy prediction control strategy have rapidly improved, compared with simple split (look-up table) control strategy. In the next step, this control strategy will be applied with actual EV through"dSPACE autobox".
