<p><P>PROBLEM TO BE SOLVED: To prevent torque fluctuation and shift shock of an engine when an engine control mode is returned to an accelerator pedal following control in normal traveling from an engine control in a shift change. <P>SOLUTION: In a power transmission device for a vehicle equipped with a clutch 3 between an engine 1 and a transmission 4, a clutch controller 6 to disconnect the clutch 3 in gear shifting, and to connect the clutch 3 when the gear-shifting ends is provided with a timer means 62. The timer means 62 controls the time to start control of connecting the clutch according to an engine state or the like. Thus, since the increasing state of clutch connection quantity is changed and the change state of the number of rotation of the engine is changed, when the engine control mode is returned from the engine control in the gear-shifting to the accelerator pedal following control in normal traveling, the torque of the engine is preventing from fluctuating due to the change of the control mode. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
