Research on Energy Management Strategy of Hybrid Electric Vehicle

Energy and environment problems prompt hybrid cars’ development towards more energy-efficient and environmentally friendly directions, whereas, the vehicle comfort also requires the automobiles have good driving performance. As the core technology of the hybrid electric vehicle, energy management strategy achieved a reasonable distribution of torque between engine and motor, in order to obtain maximum fuel economy performance, low emission and good driving performance. This paper puts forward the development direction of the energy management strategy in today’s global hybrid vehicle, and aims to provide a fast learning and research direction for the researchers, through the comparison of various energy management strategies.
