HYBRID VEHICLE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To make it possible to eliminate a discomfort that a driver may feel during shifting and to improve drivability and acceleration performance of a hybrid vehicle provided with an electric motor between an internal combustion engine and a mechanical automatic transmission and configured to be able to connect the combustion engine to the electric motor via a clutch mechanism.SOLUTION: The present invention provides a control device for a hybrid vehicle that is provided with an automatic clutch mechanism 4 interposed between an internal combustion engine 1 and a motor-generator 2 and that is configured to allow the automatic clutch mechanism 4 to be switched over between a clutch connection state and a clutch disconnection state, controls the motor-generator to drive an input shaft of the mechanical automatic transmission to rotate so as to assist the vehicle in traveling and variably controls a degree of assistance in response to the magnitude of travel resistance after shifting operation on the mechanical automatic transmission is completed in the clutch disconnection state until the automatic clutch mechanism is switched into the clutch connection state during automatic shifting.SELECTED DRAWING: Figure 3
