Considering a charge-sustaining PHEV (Parallel Hybrid Electric Vehicle) as an object, the corresponding mechanical and battery constraint functions are established. For real-time controlling, the global criterion is replaced with a real-time one, and a general scheme of real-time power assigning and speed ratio optimizing are given.Based on the math models related to HEV's powertrain, a MATLAB/Simulink simulation platform was built up to calculate ideal tables of power distribution among powertrain elements and the corresponding gear shifts which will be stored into the HEV's onboard supervisory controller. Validity and real time responsibility of the instantaneous optimization control strategy are proved by simulations with typical driving cycles, revealing worthy of the strategy.
