Title:
A concavo-convex analysis program, the concavo-convex analysis method, and a concavo-convex analysis device
Document Type and Number:
Japanese Patent JP6260216
Kind Code:
B2
Abstract:
An unevenness analyzer obtains travel data of a vehicle. The unevenness analyzer identifies travel data for a predetermined period from a stopped state of the vehicle based on a travel status of the vehicle indicated by the obtained travel data of the vehicle. The unevenness analyzer, even when the travel data of the vehicle indicates movement at a same speed, performs with respect to travel data that belongs to the obtained travel data, comparison with travel data that does not belong to the identified travel data, and execution of road surface unevenness detection by a lowered sensitivity.
