GEAR SHIFTING CONTROL METHOD, GEAR SHIFTING CONTROL DEVICE AND GEAR SHIFTING CONTROL SYSTEM FOR HYBRID POWER SYSTEM, AND HYBRID POWER SYSTEM

摘要

Disclosed are a gear shifting control method, gear shifting control device and gear shifting control system for a hybrid power system, and a hybrid power system. The gear shifting control method comprises the following steps: an out-of-gear control step of controlling a clutch (K0) so same is completely disengaged and a transmission so same exits an initial gear; a synchronous speed regulation step of controlling an electric motor (EM) so same carries out speed regulation such that the speed of a target-gear gear of the transmission matches the speed of a corresponding synchronous meshing mechanism; an in-gear control step of controlling the transmission so same enters a target gear; and a clutch (K0) engagement step of controlling the electric motor (EM) and an internal combustion engine (ICE) such that the clutch (K0) is completely engaged after the speed of the electric motor (EM) matches the speed of the internal combustion engine (ICE). Since the speed of the target-gear gear synchronizes with that of the corresponding synchronous meshing mechanism by means of the speed regulation carried out by the electric motor (EM), the wear of and even damage to the synchronous meshing mechanism caused by the rotational inertia of the electric motor (EM) are avoided. In addition, the speed regulation by means of the electric motor (EM) also reduces the speed synchronization time, thereby shortening the gear shifting time.
