“…Aiming at minimizing t powertrain inertial power, a penalty factor is introduced into the definition of the pow weighted efficiency. The methodology is then applied to the two-mode hybrid powertra presented and analyzed [34][35][36], and the influence of mode selection, inertial powertra parameters, and road inclination on the actuator's operating map is carried out thou simulation results. The paper is organized as follows: Section 2 presents the mathematical model us to describe the powertrain dynamics and the equations adopted to calculate the pow weighted efficiency; the novel procedure to introduce the penalty factor and elaborate t working map for each powertrain actuator as well as the simulation results are shown Section 3.…”

Multimode hybrid powertrains have captured the attention of automotive OEMs for their flexible nature and ability to provide better and optimized efficiency levels. However, the presence of multiple actuators, with different efficiency and dynamic characteristics, increases the problem complexity for minimizing the overall power losses in each powertrain operating condition. The paper aims at providing a methodology to select the powertrain mode and set the reference torques and angular speeds for each actuator, based on the power-weighted efficiency concept. The power-weighted efficiency is formulated to normalize the efficiency contribution from each power source and to include the inertial properties of the powertrain components as well as the vehicle motion resistance forces. The approach, valid for a wide category of multimode powertrain architectures, is then applied to the specific case of a two-mode hybrid system where the engagement of one of the two clutches enables an Input Split or Compound Split operative mode. The simulation results obtained with the procedure prove to be promising in avoiding excessive accelerations, drift of powertrain components, and in managing the power flow for uphill and downhill vehicle conditions.

“…Due to the large slip loss of belt drive and the rigidity of fixed axis gear meshing drive, many new structures have emerged, such as gear box type and PG(s) type. At present, the power coupling device is mainly concentrated in CVT [48][49][50] and EVT [51]. Figure 4 shows the three existing electromechanical power coupling systems and its various structures, and the structures with gray backgrounds are PG(s) type, which is a main concern in this paper.…”

Increasing environmental issues and energy crises led to rapid developments of hybrid electric vehicles, especially the planetary hybrid powertrain system (PHPS). This paper presents a comprehensive review of the PHPS, focusing primarily on contributions in the aspect of configuration, classification and comparison. In this work, a new classification method for PHPS architectures is proposed according to the number of electric motors (EMs). In addition, two kinds of PHPS, in the new classification framework, are extensively emphasized in terms of its architectures, advantages and disadvantages. Furthermore, the port diagrams of representative architectures are presented to provide an intuitive method for power flow representation. Finally, a conclusion is made to provide an insight for developing PHPS as well.
