Abstract

A hierarchical control system is established based on a newly developed full hybrid vehicle with the structure of single motor and double clutches, energy management strategy based on “ICE efficiency optimization” is instituted and the dynamic coordinated control for engine start while driving is studied. The energy management strategy is validated by a developed forward simulation model, a fuel consumption reduction of 34% in the NEDC driving cycle is achieved. The effect of the dynamic coordinated control for engine start while driving is proved by drum and road test.
