Abstract

Traditionally a gear shift with clutch and synchronizer control makes the synchronization phase unnecessarily long torque gap time. Based on the benefit of a single shaft parallel hybrid electric bus (PHEV), fast gear shifting and reducing the shafts speed oscillation can be realized by controlling the electric machine with Model Predictive Control (MPC) method instead of sliding the clutch and synchronizer to a torque-free state in the transmission. Detailed mathematical models of different driveline states are presented and to improve driving comfort. Theoretical and simulation analysis results are compared with experimental ones from the road experiment in equal conditions in order to prove the validity of the gear shifting control strategy.
