    Abstract: A road surface damage detection device is configured to calculate, for each of road sections, a maximum variation rate that is a maximum value of a variation amount of a wheel speed per unit time in each of vehicles. The device is configured to periodically select, for each of the road sections, a maximum value from the maximum variation rate of each of the vehicles in a prescribed period, set the selected maximum value as a section maximum variation rate, and determine whether or not the road surface damage has occurred by comparing a determination target value with a positive threshold, the determination target value being obtained by subtracting a comparison value, based on at least one of the section maximum variation rates set before last time, from the section maximum variation rate that is set latest.
