Research on the Control Strategy of the Driving System for a Kind of Hybrid Electric Vehicle

The features of driving system, the parameter matching and the control strategies of hybrid electric vehicle have determined the dynamic performance, the fuel economy, the emission characteristics, the manufacturing cost and the weight of the vehicle. In this paper, a kind of hybrid electric vehicle is considered as the research object and the control strategy of the driving system of this hybrid electric vehicle has been analyzed. Eventually, based on the parallel auxiliary driving, the system parameters have been selected according to the relevant system standards and the requirements for performance. At the same time, on account of the SOC torque balance control strategy, the simulation model of the whole system has been established by Matlab/Simulink. This simulation has verified the feasibility of the design and the effectiveness of the control strategies, which has achieved the desired goals. Compared with the traditional vehicles, this hybrid electric vehicle has improved the fuel economy and reduced the emissions.
