An input drive power applied to an automatic transmission is sequentially recognized. When there is a demand for the automatic transmission to make a gear shift, a clutch mechanism is disengaged, and a drive power generated by an electric motor connected to the automatic transmission at an output side of the clutch mechanism is controlled depending on the input drive power (input drive power immediately prior to a gear shift) that is applied to the automatic transmission immediately before the clutch mechanism starts to be disengaged. The drive power generated by the electric motor is controlled such that a drive power equivalent to the input drive power immediately prior to a gear shift is applied from the electric motor to the automatic transmission.

[ What is claimed is:] [1.]1. A control system for controlling a hybrid vehicle having an engine for propelling the hybrid vehicle, said engine having an output shaft, an automatic transmission connected to the output shaft of the engine for transmitting an output power of said engine to drive wheels of the hybrid vehicle, clutch means connected between said output shaft of the engine and said automatic transmission, for selectively applying the output power of said engine to said automatic transmission, an electric motor connected to said automatic transmission at an output side of said clutch means for transmitting an assistive output power for assisting the output power of said engine via said automatic transmission to said drive wheels, clutch control means for successively disengaging and engaging said clutch means in response to a demand for said automatic transmission to make a gear shift, and transmission control means for controlling said automatic transmission to make a gear shift when said clutch means is disengaged, said control system comprising:drive power recognizing means for recognizing a drive power applied to said automatic transmission immediately before said clutch means starts being disengaged when there is a demand for said automatic transmission to make a gear shift; andmotor control means for controlling a drive power generated by said electric motor to apply a drive power which is substantially equal to the drive power recognized by said drive power recognizing means, from said electric motor to said automatic transmission when said clutch means is disengaged.
