The Power System Active-Synchronizing Control of the PHEV during the AMT Shifting Process
For the parallel hybrid electrical vehicle (PHEV) with motor equipped in front of the transmission, the inertia of the transmission-input increases with the power system and the clutch assembly. To reduce the synchronizer slipping friction power, the input speed of the transmission should be controlled, so the active-synchronizing control is applied. To enhance the speed-adjusting precision and shorten the synchronizing time, engine-motor joint speed-adjusting-control is utilized. Finally, a vehicle simulation is carried out, and the test result proves that the method is feasible.
