Automotive engineers and researchers have proposed different Series-Parallel Hybrid Electric Vehicle SP-HEV topologies. The Toyota Hybrid System (THS) is the most known SP-HEV based vehicle, but alternative solutions such as Electric Variable Transmission (EVT) have been also proposed. Efficient comparison between these different solutions is a key point in order to estimate the added value of each topology. This paper presents the application of optimal control to two seriesparallel hybrid architectures for efficiency assessment purpose. The dynamic programming method is applied to the THS as well as to a virtual hybrid vehicle with an EVT. The way to take into account the supplementary degree of freedom provided by the decoupling of wheels and engine in both topologies is presented. The optimal fuel consumptions are then compared on different driving cycles and bring out an over consumption of the EVT topology. Then, a parametric study shows that inserting an appropriate gear ratio on the ICE shaft can improve the EVT efficiency that becomes close to the THS efficiency.

The problem of vibration caused by frequent engine start-stop which improves fuel consumption is serious in hybrid electric vehicle (HEV). In the new HEV power train-electrical variable transmission, which based on dual mechanical port machine (DMPM), this problem is also severe. In this paper, a control method has been proposed to reduce vibration in the process of engine start-stop. This vibration reducing control method is to add the compensation torque on the torque reference of OM to eliminate rapid variation of IM torque. Experiment results showed that the control method reduces vibration significantly in the process of engine start, which improves the ride quality of HEV.

“…In references [1] and [2], the model of DMPM shows that electromagnetic coupling and mechanical coupling exist between the two rotors in the DMPM, which brings great influence to the performance. The field coupling of the two air gap varies with the character and height of out rotor, array of magnet, etc, introduced in references [3] and [4]. The factor that caused field coupling is studied in [5], based on which the DMPM is designed just as two separate motors connected mechanically to avoid the control difficulties.…”

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.
