Research on Torque Distribution Strategy for ISG Hybrid Electric Cars
Based on the configuration and working state analysis of the ISG hybrid electric cars,the torque distribution strategy of a hybrid system is designed to delineate the maximum and minimum work torque curves of the engine,achieve optimization of engines range so as to make sure the target torque of the engine and ISG motor,and finally through the calibrated driving characteristics MAP and battery SOC state to achieve the calculation of total vehicle torque demand.Taking the Hafei Saibao ISG hybrid car as a test model,the test of fuel economy and emissions carried out under specific conditions showed that using the torque distribution strategy has increased by 12.8 %of the ISG hybrid car fuel economy and improved emissions performance to some extent compared to the traditional Hafei Saibao cars.
