<P>PROBLEM TO BE SOLVED: To provide a method for reducing shift impact of a hybrid vehicle, capable of achieving quick shift, while reducing an impact and vibration generated in shift. <P>SOLUTION: The method includes: a slip preparation stage for determining that a shift request is made, and for reducing a clutch oil pressure to a preliminarily set target oil pressure from the point of time when the shift request is made; a slip maintaining stage for, when the clutch oil pressure reaches the target oil pressure, feedback-controlling the clutch oil pressure so that the clutch slip quantity can be maintained to fixed slip quantity; and a clutch lockup completion stage for making a rise in a clutch oil pressure from a point of time when the shift is completed, and for making a rise in the clutch oil pressure to the maximum pressure for lockup. <P>COPYRIGHT: (C)2011,JPO&INPIT |
