Claim 7:
8. A method for road surface recognition, the method comprising:
determining, by a controller comprising a processor, a vertical location signal of a preceding vehicle using a frontward-direction sensing sensor mounted in a host vehicle;
computing, by the controller, a distance in a longitudinal direction between the host vehicle and the preceding vehicle, and a distance traveled by the host vehicle, in response to the vertical location signal being at or above a setting value;
detecting, by the controller, a speeding prevention obstacle located on a road surface, based on a value of a difference between the distance traveled by the host vehicle and the distance in the longitudinal direction between the host vehicle and the preceding vehicle;
controlling travel of the host vehicle according to a location of the speeding prevention obstacle;
selectively providing a warning of a presence of the speeding prevention obstacle; and
storing, in response to an absolute value of the difference between the distance traveled by the host vehicle and the distance in the longitudinal direction between the host vehicle and the preceding vehicle being at or below a threshold,
wherein the frontward-direction sensing sensor computes the distance traveled by the host vehicle using a change in a value of a distance in the longitudinal direction to an arbitrary stationary object located in front of the host vehicle.
