AUTOMATIC TRANSMISSION

摘要

An automatic transmission includes engagement mechanisms whose engagement states among the engagement mechanisms are changeable to achieve each of shift stages of the automatic transmission, a detector, and a determination device. The detector is configured to detect the engagement states of the engagement mechanisms. The determination device is configured to determine that abnormality has occurred in a case where the engagement states detected by the detector do not match a predetermined engagement state.

1. An automatic transmission that achieves each of a plurality of shift stages by a combination of engagement and release of a plurality of engagement mechanisms, the automatic transmission comprising:
a detection unit that detects an operating state of the engagement mechanisms; and a determination unit that determines whether or not abnormality has occurred, based on a result of detection performed by the detection unit, wherein the determination unit determines that abnormality has occurred in the case where an operating state of the engagement mechanisms does not match a predetermined operating state.
