Abstract:
1. A control device for an automatic transmission which transitions from a non-running state to a running state by a friction engaging element which is operated by oil pressure which transitions from a released state to an engaged state, comprising: a shift position detection unit which detects shift positions, including a first shift position which corresponds to the non-running state and a second shift position which corresponds to the running state, based upon a position of a shift actuation mechanism; an oil pressure control unit which raises the oil pressure supplied to the friction engaging element to an elevated state, when the shift position detection unit detects that the shift position is the first shift position; a running request detection unit which detects a running request irrespective of the position of the shift actuation mechanism; and a starting control unit which further raises the oil pressure supplied to the friction engaging element to a power transmission state, if the running request is detected, wherein the running request detection unit detects the running request if, irrespective of whether or not the position of the shift actuation mechanism is a position which corresponds to the second shift position, the shift position detection unit detects that the position of the shift actuation mechanism is the first shift position.
