Abstract: A control device for a transmission including m (m?3) solenoid valves and configured to establish a plurality of shift speeds by engaging n1 (2?n1<m) engagement elements using hydraulic pressures of n1 solenoid valves among the m solenoid valves. A current threshold setting unit sets respective currents to be applied to solenoids of n2 (n1<n2?m) solenoid valves corresponding to n2 engagement elements at the time when braking torque acts on an output shaft of the transmission with the n2 engagement elements engaged as current thresholds. A determination unit determines whether or not braking torque is generated on the output shaft of the transmission by comparing respective current values to be applied to the solenoids of the n2 solenoid valves and the set current thresholds corresponding to the solenoids of the n2 solenoid valves.

Abstract: A control device for an automatic transmission. The control device configured to determine if the automatic transmission is in such a condition that the automatic transmission accelerates the vehicle at predetermined acceleration when the output command value is transmitted to the control device for the motor. The output command value is not cancelled if it is determined by the determining means that the automatic transmission is not in such a condition that the automatic transmission accelerates the vehicle at the predetermined acceleration, and the output command value is cancelled if it is determined by the determining means that the automatic transmission is in such a condition that the automatic transmission accelerates the vehicle at the predetermined acceleration.
