“…The addition of fixed gear ratios allows the system to achieve better fuel economy. Mashadi et al [12] also put forward an innovative power-split device, which consists of two planetary gear sets and two clutches. The powertrain can work in two different power-split modes by locking/unlocking the two clutches.…”

Abstract:In recent years, increasing concerns regarding environmental pollution and requirements for lower fossil fuel consumption have increased interest in alternative hybrid powertrains. As a result, this paper presents a novel hydraulic/electric synergy powertrain with multiple working modes. The three energy sources (i.e., engine, battery, and hydraulic accumulator) in this configuration are regulated by a dual planetary gear set to achieve optimal performances. This paper selects the component sizes of a hybrid electric vehicle (HEV), a hydraulic hybrid vehicle (HHV), and a hydraulic/electric synergy vehicle (HESV), based on the dynamic performance of a target vehicle (TV). In addition, this paper develops the forward simulation models of the four aforementioned vehicles in the MATLAB/Simulink/Driveline platform, in which the fuel economy simulations are carried out in relation to the Chinese urban bus cycle. The simulation results show that the fuel consumption of the three hybrid vehicles is similar, but much better than, that of the TV. Finally, based on the operating cost calculations over a five-year working period, the lowest cost ranges of the three hybrid vehicles are determined, which provides a method for choosing the optimal hybrid scheme.

Hybrid electric vehicles have excellent energy efficiency and emission performance. Power split device (PSD) is a key component that directly affects the control strategy of power systems, the economic consumption of fuel, and the dynamic performance of vehicles. A differential-based PSD was proposed in this paper. A traditional differential was taken as the prototype and a new design method is proposed to retrofit the differential into a PSD. First, a comprehensive approach that includes theoretical analysis and software simulation was used to analyze the possibility as well as the necessity of retrofitting the differential into PSD. Then the differential was retrofitted. Finally, finite element analysis and bench test were conducted. Results showed that applying the retrofitted differential as PSD is practicable.

“…As a power summing unit, the planetary gearbox combines two power sources and the output shaft. The improved CHPTD could achieve higher efficiency than other existing hybrid powertrain because of its efficient power distribution via planetary transmission [2][3][4][5][6]. Several sets of clutch-brake system are used together with mechanical transmission for changing operating modes of the powertrain and adjusting gear ratio.…”

Clutch-brake system is important element in advanced Compact Hybrid Planetary Transmission Drive (CHPTD). The proper designed clutch/brake system equipped with planetary transmission and additional gears could save energy and improve performance of hybrid powertrain, especially during frequent vehicle starting and regenerative braking. This paper dedicate to design of clutch engaging control strategy in ICE starting procedure. The control of each element in CHPTD during ICE starting is described. Different clutch engaging control strategies are proposed and validated on laboratory stand for various conditions.Optimized control strategy for clutch engaging is selected by analysing the simulation and experimental test results.
