Abstract: 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.

Abstract: A vehicle information processing system includes a vehicle information processing device including one or more processors. The one or more processors are configured to receive input information including information on a wheel velocity of a vehicle, and calculate a velocity of the vehicle traveling on an expressway as a feature by using the input information. The input information is information that is received during a period in which a predetermined condition is satisfied out of a period in which the one or more processors receive the input information. The predetermined condition indicates that the vehicle is traveling on the expressway.

Abstract: An information processing device includes a processor. The processor receives a requested acceleration as one of motion requests for a vehicle from each of sets of application software. The processor performs arbitration of requested accelerations that are received. The processor outputs an instruction signal for controlling an actuator of the vehicle based on a target acceleration that is a result of the arbitration of the requested accelerations. The processor acquires a detection value from an acceleration sensor installed in the vehicle. The processor performs first determination processing to determine whether an external impact has been applied to the vehicle, based on the target acceleration in addition to the detection value.
