<P>PROBLEM TO BE SOLVED: To provide a shift control device for a hybrid vehicle in which a power take-off shaft installed in a transmission is connected to an electric motor, the shift control device enabling the driving timing of the electric motor to be quickened and enabling failure on power transmission to be avoided in shift during traveling using the electric motor. <P>SOLUTION: When a shift request is detected, a main clutch 4 and a sub-clutch 22 are disconnected, then shift is performed by a shift control means 40d, and the rotational speed of an internal combustion engine is synchronized with the rotational speed of the input shaft of a transmission, and the rotational speed of the electric motor is synchronized with the rotational speed of the driven shaft of the transmission by a synchronization control means 40f, then the simultaneous connection of the main clutch and the sub-clutch is commanded under the control of the shift control means 40d. During the shift, output torque of the internal combustion engine and the electric motor are each controlled to zero and the shift is completed, and when the main clutch 4 is connected, the output torque of the internal combustion engine is restored, and when a sub-clutch 22 is connected, the output torque of the electric motor 30 is restored. <P>COPYRIGHT: (C)2011,JPO&INPIT |
