Hybrid Electric Vehicle Driving Research Based On Interior Permanent Magnet Synchronous Motor

Energy crisis and environmental deterioration are two important problems of global development.The design of low energy consumption and low emissions vehicle can abate the pressure of energy absence and improve the quality of environment.Hybrid electric vehicle(HEV) has many advantages,such as low energy consumption,low emissions,long drive distance etc.HEV has become an active research aera.So it is imperative to develop the HEV and the new motor driving control system.The structures and features of the three hybrid power systems were analyzed and compared in this paper,the serial and parallel hybrid electric vehicle(SPHEV) had been chosen.After the driving features of the motors were analyzed and compared, the Interior Permanent Magnet Synchronous Machine(IPMSM) was chose as the driving motor.The engine and battery of HEV were also analyzed simply in this paper.Based on SPHEV structure and IPMSM driving motor,two IPMSM(MG1 and MG2) had been selected and the main parameters of IPMSM were designed.Some stimulations and analyses of the main work status of two IPMSMs were done.Otherwise the hardware and software of IPMSM were designed.DSP is as center control unit in the hardware platform and control system is established integrally after the software is designed.At last,in simulation software Advisor,parameters' setting,simulation modules' mathematical description,modules' building had been mainly discussed.The secondary developments for the designed composite SPHEV had been done based on the Prius SPHEV in Advisor.The vehicle,generator,motor and composite power module had been shown.The simulation results had proved the feasibility of the control strategy.The analyzed results showed that One-Hundred-Kilometer Fuel Consumption and emission of the vehicle can meet the needs of vehicle development and greatly improve the energy saving and environmental protection.
