PROBLEM TO BE SOLVED: To improve a gear shift transient characteristic while accurately compensating the torque shift independently of the operating condition by providing a quick shift time compensating means for prohibiting the torque shift compensation of a feed forward control means in the case where the changed variable of a target achievement change gear ratio. SOLUTION: When a quick shift such as foot release up-shift is started, change gear ratio changing speed exceeds the predetermined value at a time T (K-n). During the time from the time (K-n) to a time T (K), namely after a control period (n) is passed, when an acceleration pedal is released, an achievement change gear ratio RTOmap is reduced to the predetermined valve at a Hi-side, and the change gear ratio changing speed is less than the predetermined value. At this time T (K), in the case where the achievement change gear ratio changed variableΔDRTO obtained on the basis of variable DRTO 1, 2 and RTOts 1, 2 is larger than the achievement change gear ratio changed variableΔTSRTO, the feed forward compensation change gear ratio is set to 0, and the torque shift compensation by the feed forward is interrupted. |
