摘要:
A duty ratio for controlling an engagement force of a friction engagement device on the side of upshift engagement is corrected by an amount corresponding to an intermediate correction control value in the course of the shift. In addition, on a prerequisite condition that learning correction of a constant standby pressure control value at the start of the shift is converged, learning correction is performed for the intermediate correction control value according to a gradient of a turbine speed. Thus, a shift shock is prevented from occurring due to abrupt engagement of the friction engagement device and the like at the completion of the shift.
