摘要: The automobile industry is facing challenges owing to stringent emission regulations and adaptation to the evolving technologies. The launched hybrid vehicles are facing challenges regarding the cost-fuel benefit trade-off as well as the complexity in packaging the E-Machine between Internal Combustion Engine (ICE) and transmission system. The P3 hybrid configuration with AMT system is a way to achieve better drivability and fuel benefit. This paper focuses on development of Dual Control Strategy (DCS) for performance improvement in retrofitted 48 V P3 hybrid AMT vehicle. The DCS is developed based on rule based approach and Adaptive-Equivalent fuel Consumption Minimization Strategy (A-ECMS). The proposed control strategy includes decision making of mode shift between electric and ICE mode, optimal torque distribution between ICE and E-machine, equivalence cost factor computation with kinetic energy at the wheel and drivability consistency subjective to system limits during E-Creep, E-Launch and mode shift. The overall energy transfer efficiency to the wheels is improved by considering the global constraint, State of Charge (SOC) difference and the local constraint of 48 V battery, E-Machine and ICE. The 48 V P3 hybrid AMT vehicle with DCS can provide 10 kW power during torque assist or electric drive and −12 kW during recuperation or ICE mode, which results an elevated real time fuel economy by 66.7% and promises a improved driving performance in Bangalore city Driving Cycle (BDC).
