An information processing method includes determining whether at least one condition is satisfied, and calculating a feature quantity on flexibility of a tire when all of the at least one condition is satisfied. The at least one condition includes at least one of a first condition that an absolute value of an angular velocity of a steering wheel is smaller than a first reference value, and a second condition that an absolute value of a vector sum of vehicle accelerations of the vehicle including the steering wheel and wheels each provided with the tire is smaller than a second reference value.

Information processing device, vehicle, information processing method, and non-transitory storage medium

The vehicle movement control apparatus of the disclosure sets an update movement route as a target movement route when an update condition is satisfied. The apparatus acquires a turning characteristic, an acceleration characteristic, and a deceleration characteristic of a vehicle while executing an automatic movement control to cause the vehicle to move along the update movement route. The apparatus updates vehicle behavior characteristic data so as to represent actual vehicle behavior characteristics, based on the acquired turning characteristics, the acquired acceleration characteristic, and the acquired deceleration characteristic.
