Patent ID: 8249784

Claim:
A control apparatus that controls an automatic transmission in which a first shift position is achieved by engaging a first element and engaging a second element, a second shift position is achieved by engaging a third element and engaging a fourth element, an intermediate shift position exists between the first shift position and the second shift position, the third element does not transmit an input torque of the automatic transmission to an output shaft of the automatic transmission when only the third element is engaged, and the fourth element transmits the input torque of the automatic transmission to the output shaft of the automatic transmission when the fourth element is engaged, the control apparatus comprising: a first determination unit that determines whether or not engagement of the fourth element is yet to begin during a direct shift in which a shift is performed from the first shift position to the second shift position without passing through the intermediate shift position by disengaging the first element, disengaging the second element, engaging the third element, and engaging the fourth element; a second determination unit that determines whether or not a shift is to be performed to a third shift position which is different to the second shift position; and a control unit that halts the direct shift and executes a shift to the third shift position when the second determination unit determines that a shift is to be performed to the third shift position before engagement of the fourth element begins.
