Claim 0:
1. A system with road surface recognition, the system comprising:
a processor configured to:
determine a vertical location signal of a preceding vehicle using a frontward-direction sensing sensor mounted in a host vehicle;
calculate 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;
detect 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;
compute 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;
control travel of the host vehicle according to a location of the speeding prevention obstacle;
selectively provide a warning of a presence of the speeding prevention obstacle; and
store a location of the speeding prevention obstacle, 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.
