  • Patent number: 7841963
    Abstract: A shift speed control that, in the case in which it is determined that reverse jump shifting, which returns to a previous shift speed, has occurred during jump shift control, a load amount determining means determines whether a load amount that is applied to friction engagement elements is within a permitted range. Based on the result of this determination, a multiple control permitting means permits execution of multiple shift control for the reverse jump shifting, and when permitted by the multiple control permitting means, the shift control means executes multiple shift control for reverse jump shifting. In addition, in the case in which the shift control means is not permitted by the multiple control permitting means, the shift control means executes reverse jump shift bypass control, and shifts to a shift speed to be shifted to after temporarily shifting to an intermediate shift speed.
