Abstract
A profiler arranged to be used on a host vehicle. The profiler is capable of (a) receiving data collected by the profiler while traveling over a surface and (b) generating a surface profile using the data collected with no minimum speed requirement. Since there is no minimum speed requirement, the profiler is capable of generating valid, repeatable and reliable road surface profiles in situations not previously possible, such as during a stop, during acceleration of the host vehicle, during deceleration of the host vehicle, or while the host vehicle is traveling at very low speeds below thresholds typically required for prior profilers.
