<p>PROBLEM TO BE SOLVED: To properly switch an allowable rotation direction of a two-way clutch (TWC) to a direction in which a forward stage is established from a direction in which a rearward stage is established, in an automatic transmission which switches between the forward stage and the rearward stage by switching the allowable rotation directions of the TWC which can switch the directions for allowing rotation.SOLUTION: An ECU 30 detects a shift range position of an automatic transmission 10, and detects an allowable rotation direction of a TWC 22. When a neutral range position is detected as the shift range position, and a direction for establishing a rearward stage is detected as the allowable rotation direction of the TWC 22, the allowable rotation direction of the TWC 22 is switched to a direction in which the rearward stage is established.</p> |
