Abstract
A control device of an automatic transmission includes a motor control portion to control an output of a motor that executes a control operation on a clutch control portion. The motor control portion includes a target motor current computation portion that computes a target motor current according to a desired driving state, a motor current detection portion that detects plural motor currents respectively corresponding to plural detection timings, a selection portion that selects a motor current corresponding to the desired driving state among the detected plural motor currents, and a motor driving portion that applies feedback control on an output of the motor according to a difference between the target motor current and the selected motor current. Hence, not only can the most suitable clutch control be applied for each gear-change interval at gear change, but also the comfortable feeling during the driving and the fuel efficiency can be enhanced.
