Abstract :
CJY6470 parallel hybrid electric vehicle (CJY6470PHEV) is a light type off-road vehicle developed by the authors. Its energy management system (EMS) has been designed using the T-S fuzzy model and fuzzy control toolbox in MATLAB 6.5. In order to simplify the system, it is divided into the energy regenerative braking system (ERBS) and the EMS in the vehicle normally driving modes. As the relationship of the inputs and outputs is very clear for ERBS, the T-S fuzzy model completely fits the system. When it is used to the EMS in the vehicle normally driving modes, it can simplify the relationship of the inputs and outputs, as well as make the engine operate in the optimum cycles. The starter and electrical motor also operate in terms of the modes drawn up. The results show that the EMS designed with the method is feasible and rational.
