In order to make the automatic clutch better in accordance with the “fast, slow, fast” rules for action, this paper presents a multi-mode control. According to clutch engaging process we take P control before the half juncture, engagement speed control section adopts fuzzy control, synchronous speed control section of the use of PID overall control strategy. The experimental results show that, this...
In this paper, an innovative power-split device (PSD) is introduced, and its application in a hybrid powertrain system is studied. The new PSD is a mechanism that allows operation in two different power-split modes through locking/unlocking of two clutches. In one mode, the PSD operates similar to a standard planetary gear unit, and in the other mode, it works the same as a compound planetary set...
The clutch engagement control of automated mechanical transmission (AMT) system is the core and difficult issue in the development of AMT. This paper analyzes the clutch engagement process during starting in a bid to realize a stable starting with minor jerk and friction work. On the basis of the driverpsilas intention, the vehicle work states and the road information, fuzzy controller was used to...
In the parallel hybrid electric vehicle (PHEV) the load torque and speed control are the key point for efficient driving vehicle. A dynamic model of PHEV derived by an induction motor (IM) and an internal combustion engine (ICE) is made using Simulink package in Matlab. A comparison between a conventional PID controller and a fuzzy logic control (FLC) method. Also, analysis of IM with FL at variable...
