Different architectures and modes of operation of HEV based on permanent magnet-electric variable transmission with rule-based and fuzzy logic global control strategy

In this paper, permanent magnet-dual mechanical ports (PM-DMP) machine is used as an electrical variable transmission (EVT), instead of the Toyota hybrid system (THS) transmission, in hybrid electric vehicle (HEV). In this paper, a new tactic to strategise the power management and torque distribution in the studied HEV system is developed. This strategy is based on the combination of rule-based and fuzzy logic control (RB-FLC). According to this strategy, different architectures with all modes of operation of the series/parallel HEV based on PM-EVT have been achieved. Using the vehicle specifications, engine, battery, and other control parameters of the Prius HEV, the appealing features of PM-EVT unit and the proposed RB-FLC power management strategy are explored in comparison to the SPHEV obtained from ADVISOR 2002. The obtained results give a specific conclusion that the Prius SPHEV can be successfully replaced by the HEV based on the PM-EVT with the proposed control strategy.
