Original Abstract Submitted

An information processing device includes one or more processors. The one or more processors are configured to: acquire an actual lateral acceleration being an actual measured value of a lateral acceleration of a vehicle detected by an acceleration sensor mounted on the vehicle over a prescribed period that is predetermined; acquire an estimated lateral acceleration being an estimated value of the lateral acceleration over the prescribed period based on a parameter different from the actual lateral acceleration; calculate an error of the actual lateral acceleration with respect to the estimated lateral acceleration based on the estimated lateral acceleration and the actual lateral acceleration acquired over the prescribed period; determine that there is wheel loosening in the vehicle on condition that the calculated error is equal to or greater than a prescribed value that is predetermined.
