  • Patent number: 11796054
    Abstract: A storage device stores a mapping data entry that specifies a mapping and includes data learned through machine learning. A detection value of an oil temperature sensor is an oil temperature detection value. When oil temperature relation data, which is data corresponding to time series data of the oil temperature detection value, is input to the mapping as an input variable, the mapping outputs an output variable that determines whether a frictional engagement element has an anomaly. Processing circuitry executes an obtainment process that obtains the input variable and an anomaly determination process that determines whether the frictional engagement element has an anomaly based on the output variable that is output from the mapping as a result of inputting the input variable obtained in the obtainment process into the mapping.
