Field: Mechanical elements (Mechanical engineering)
Classification: CPC G  F  B | IPC B  F  G

Claim 0:
1. An anomaly determination apparatus for a vehicle that includes a transmission, which transmits power using a gear, the anomaly determination apparatus comprising:
an execution device; and
a memory device, wherein
the memory device is configured to store map data, the map data defining a pre-trained map, and the pre-trained map having been trained through machine learning,
when a variable representing time-series data of a rotation speed of the gear is fed to the map as an input variable, the map outputs a state variable representing a state of the gear as an output variable, and
the execution device is configured to execute:
an obtaining process that obtains the variable representing the time-series data as a value of the input variable; and
a determination process that determines whether there is an anomaly in the transmission based on a value of the output variable that is output by the map when the value of the input variable is fed to the map.
