Patent ID: 7226383

Claim:
A control device for a hybrid vehicle, comprising: an engine driving drive wheels via an engine-power transmission path; a drive motor driving said drive wheels via a motor-power transmission path; a power generating motor provided to said engine-power transmission path and generating an electric power by said engine; a coupling having an input-side shaft and an output-side shaft and provided to said engine-power transmission path and switched between a connection state of transmitting a power of said engine to said drive wheels and a disconnection state of cutting off the transmission of the power of said engine to said drive wheels; a first revolution sensor for detecting a revolution speed of said power generating motor; a second revolution sensor for detecting a revolution speed of said drive motor; and a control unit, wherein, in the case where a power of said drive motor is transmitted to said drive wheels and said coupling is intended to switch from the disconnection state to the connection state, said control unit controls a revolution speed of said power generating motor based on a revolution speed of said drive motor, said control unit synchronizes said input-side shaft and said output-side shaft based on revolution speeds detected by said first and second revolution sensors, said control unit connects said coupling, and said control unit controls the power of said drive motor and the power of said engine in accordance with a required power of the vehicle after said coupling is connected.
