Fuzzy Energy Control Strategy of Through-To-Road Hybrid Electric Vehicle

چکیده مقاله

New energy management strategies for hybrid electric vehicles (HEV) play an important role on HEV's future. In order to achieve high performances, less fuel consumption and pollution, and higher efficiency, modern strategies should be employed. Fuzzy approach is one of the most popular and powerful techniques in energy management and optimization which are developed for HEVs. On the other hand, separated-axle or through-to-road (TTR) parallel HEV has the simplest structure among other type of HEVs in addition to desirable performance. Shaheb 2 is a TTR parallel HEV type based on Pride platform that has been manufactured and designed in university of Kashan. This paper presents a new energy management strategy with two fuzzy controllers for battery state-of-charge (SOC) and developed torque of Shaheb 2. A comprehensive model of Shaheb 2 as well as its control strategy has been developed using ADVISOR. Low fuel consumption, high efficiency, and simple control strategy are the other benefits among various energy management strategies. Simulation results confirm the advantages of proposed fuzzy controller rather than conventional on/off strategy.
