Title:
UNEVENNESS ANALYSIS PROGRAM, METHOD, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/072468
Kind Code:
A1
Abstract:
In this unevenness analyzer (100), the sensitivity of detecting the unevenness of a road surface while a traveling vehicle (110) is accelerating from a stop or decelerating to a stop is reduced to below the sensitivity during a forward travel at a constant speed, and the unevenness is detected. Also in this unevenness analyzer (100), the sensitivity of detecting the unevenness of a road surface while a traveling vehicle (110) is turning right or left is reduced to below the sensitivity during a forward travel at a constant speed, and the unevenness is detected. Also in this unevenness analysis device (100), the sensitivity of detecting the unevenness of a road surface is increased above the sensitivity during a forward travel at a constant speed at a measurement point in which a composite acceleration is greater than or equal to a prescribed value, and the unevenness is detected. In the composite acceleration, the vertical acceleration combines longitudinal acceleration, lateral acceleration, and vertical acceleration.
