Abstract

The fuel efficiency are related to the engine temperature. The total fuel consumption of a warmed-up engine is less than that of the cold-start engine for the same driving cycle. Hybrid electric vehicle (HEV) allows the motor to work during the engine warming-up process. Optimizing torque distribution ratio can help reduce engine fuel consumption of the warm-up process. The traditional energy management strategy, which does not consider the engine temperature, is designed for a warmed-up engine. In this paper, an energy management strategy with considering engine warming-up is formulated.
