Classification: CPC G  F  B | IPC B  F  G

Claim 20:
21. The anomaly determination apparatus according to claim 1, wherein
the map is a first map that outputs, as an output variable, a state variable indicating whether the gear is damaged when fed with the input variable,
the map data is first map data that defines the first map,
the determination process is a first determination process,
the memory device is configured to further store second map data and third map data, each of the second map data and the third map data defining a pre-trained map, and the pre-trained map having been trained through machine learning,
the second map data defines a second map,
when fed with the input variable, the second map outputs, as an output variable, a state variable indicating whether the gear is in a state in which a rattling noise is generated as the gear rotates,
the third map data defines a third map,
when fed with the input variable, the third map outputs, as an output variable, a state variable indicating whether the gear is in a state in which a whining noise is generated as the gear rotates, and
the execution device is configured to execute:
a second 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 second map when the value of the input variable is fed to the second map, and
a third 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 third map when the value of the input variable is fed to the third map.
