Abstract：To solve the problem that continuous variable dynamic system and discrete event dynamic system for hybrid electric vehicle (HEV) can not be fully described by energy control system during modeling, a new mathematic model was developed based on switched system theory. According to various operating modes, six modes were proposed, and an eighttuple representation was presented to define energy control system. Switching rules, jumping conditions and mapping sets of switching among all operating modes were established by logical judgement. Compared simulation results with ADVISOR default values from basic control strategy method, it is found that SOC value is always at optimal range of 65%-75%,and the emissions of HC,CO, NOx and PM were reduced by 17.1%,21.5%,7.3% and 2.7%, respectively. Simulation results show that switched system can be effectively applied to energy control system of HEV.
