“…Clutch states are divided into four states during gear-shifting, and mathematical models to calculate the clutch torque in each state are required in the wheel loader simulation model. For modeling and applying clutch-type automotive transmission, many researches have been conducted regarding detailed mathematical modeling of clutch and clutch control strategies for dual clutch transmission [10,11]. A simplified clutch model has been developed and used instead of using a specific mathematical model of clutch since this paper focuses on a systematic approach to analyze the working performance and energy efficiency of the wheel loader based on V-pattern working.…”

“…The two clutches have a common drum attached to the input shaft from the motor, and the friction plates are independently connected to the first and second gears, respectively. With only two gear pairs and a final drive gear in the two-speed gearbox it is a comparatively simple transmission, without the requirement to engage alternate gears using synchronizer mechanisms [8,9]. For just two gear ratios, gear shifting is realized through dual clutch control alone.…”

Dual clutch transmissions (DCTs) are recognized as being suitable for electric drive applications as they can drive with high efficiency and achieve good shifting comfort. A two-speed DCT electric drivetrain is described in this paper, comprised of only two gear pairs and a final drive gear in the two-speed gearbox. The fundamental shifting control algorithm is provided. On the testing rig of University of Technology, Sydney (UTS) powertrain lab, shifting controls and some driving cycle controls were realized. The results demonstrated that the control algorithm functioned well both in transient shifting control process and in the driving cycle conditions.

“…Taking the upshift from 1st to 2nd gear as an example, the dynamic characteristics of the shifting process are analyzed [11][12][13]. In the normal driving and shifting process without clutch, there is ω e = ω c = ω t_o · i g (n) .…”

Abstract:On the basis of the shifting process of automated mechanical transmissions (AMTs) for traditional hybrid electric vehicles (HEVs), and by combining the features of electric machines with fast response speed, the dynamic model of the hybrid electric AMT vehicle powertrain is built up, the dynamic characteristics of each phase of shifting process are analyzed, and a control strategy in which torque and speed of the engine and electric machine are coordinatively controlled to achieve AMT shifting control for a plug-in hybrid electric vehicle (PHEV) without clutch is proposed. In the shifting process, the engine and electric machine are well controlled, and the shift jerk and power interruption and restoration time are reduced. Simulation and real car test results show that the proposed control strategy can more efficiently improve the shift quality for PHEVs equipped with AMTs.
