Abstract
A range determination device is applied to an automatic transmission provided with an input portion, an output portion, and a range switching mechanism which transmits rotation of the input portion to the output portion, and which is operative to switch the range of the automatic transmission between a forward range and a reverse range, in which directions of transmitting rotation from the input portion to the output portion are different from each other. The range determination device includes a rotational state detection unit which detects a rotational state of a predetermined rotary member included in the range switching mechanism, and a determination unit which determines that the forward range or the reverse range is attained on the basis of the rotational state of the rotary member detected by the rotational state detection unit.
