Abstract
In a vehicle diagnostic system, a storage device stores data of a learned model and probability distribution data obtained by generating pieces of generated data by a learned model using pieces of sound data recorded using vehicles with identified types of anomalies and by obtaining, for each of the types of anomalies, a probability distribution of a loss variable. Processing circuitry is configured to execute a loss calculation process that generates the pieces of the generated data using pieces of diagnostic sound data and obtains data of a probability distribution of a loss variable in the pieces of the generated data as sample data and a diagnostic process that determines which probability distribution of an anomaly the sample data matches and outputs a diagnosis result indicating that a type of anomaly corresponding to the probability distribution determined to match the sample data has occurred in the target vehicle.
