  • Patent number: 9815455
    Abstract: A control device for a vehicle drive device having a speed change mechanism that attains a predetermined shift speed by engaging multiple engagement elements. The control device predicts an amount of heat generation and determines whether any jumping shift from the current shift speed to the shift speed that is the multiple shift speeds higher or lower than the current shift speed can be permitted or not between the current shift speed and the target shift speed, and if the jumping shift can be permitted, the control unit performs the jumping shift and controls the speed change mechanism so as to shift the shift speed from the current shift speed to the target shift speed.
