1. An information processing apparatus comprising a processor configured to:
acquire vehicle state information for each of a plurality of vehicles; and
acquire an output value of estimated road surface state information of a road surface on which each of the vehicles has traveled from a trained model that outputs the output value when the acquired vehicle state information is input to the trained model, the trained model having been trained in advance based on training data in which vehicle state information as training data and road surface state information as training data are associated with each other, wherein
the vehicle state information includes a wheel speed of a right front wheel of the vehicle, a wheel speed of a left front wheel of the vehicle, a wheel speed of a right rear wheel of the vehicle, and a wheel speed of a left rear wheel of the vehicle, and
the estimated road surface state information is an estimated international roughness index (IRI) that indicates road surface roughness, and
the processor is further configured to
calculate a differential value of the wheel speed of the right front wheel, a differential value of the wheel speed of the left front wheel, a differential value of the wheel speed of the right rear wheel, and a differential value of the wheel speed of the left rear wheel,
input, to the trained model, the differential value of the wheel speed of the right front wheel, the differential value of the wheel speed of the left front wheel, the differential value of the wheel speed of the right rear wheel, and the differential value of the wheel speed of the left rear wheel,
acquire an output value of the estimated IRI, and perform a control to display map data to which the output value of the estimated IRI is added.
