<P>PROBLEM TO BE SOLVED: To provide a simple and inexpensive controller of a mechanical automatic transmission that achieves a smooth gear operation as well as shift-transmission control, in the mechanical automatic transmission mounted on a hybrid vehicle. <P>SOLUTION: A shift-transmission controller 200 of the mechanical automatic transmission includes a clutch mechanism 10 interposed between a combustion engine 1A and an electric motor 1B, and a rotary shaft of the electric motor 1B connected to an input shaft 110 of a mechanical automatic transmission 100. A shift-transmission controller controls rotating speed of the electric motor 1B to be lower than the rotating speed of the input shaft 110 determined based on information on a vehicle speed and a target transmission gear ratio, in shifting gears in a direction in which a transmission gear ratio is decreased when the rotational connection of the combustion engine 1A and the electric motor 1B is disconnected and the rotational connection of the input shaft 110 and output shaft 120 of the mechanical automatic transmission 100 is released by the clutch mechanism 10. <P>COPYRIGHT: (C)2011,JPO&INPIT |
