Abstract
A mechanical engagement mechanism has regulation states out of a first state in which at least one of a plurality of rotating elements is rotatable only in a first direction and a second state in which the at least one of the plurality of rotating elements is not rotatable in both of the first direction and a second direction opposite to the first direction and a reverse gear position is to be established. A non-traveling gear position is to be established in the first state or in the second state. A processor is to switch the regulation states of the mechanical engagement mechanism from the second state to the first state when oil pressure that is detected by an oil pressure sensor becomes lower than a predetermined oil pressure after switching a shift position from the reverse gear position to the non-traveling gear position is detected.
