Abstract :
This paper presents a new full hybrid system with a PM type DMPM using a new mechanism in the decoupling of the internal combustion engine (ICE) optimal working points and the power train output shaft operation points. In this paper, the working points of this system are explained. The comparison of system efficiencies is made. The results suggest that the system proposed can obtain the same or even higher efficiency than that of Toyota Hybrid System using high speed planetary gear set. The torque coupling and decoupling of the inner and outer motors of DMPM during the steady and start-stop transient states are analyzed. A control scheme is proposed. The research results are used to drive a 38kW/52kW PM type DMPM system loaded on a SUV of about 2700kg. The maximum speed of the SUV reaches 122.5km/h.
