A method for improving the accuracy with which a road profile ahead of a vehicle may be determined. The method may include receiving a plurality of inputs corresponding to a plurality of on-board sensors corresponding to a vehicle. An on-board computer system may estimate motion of the vehicle. The on-board computer system may correct data corresponding to a forward-looking sensor of the plurality of on-board sensors by accounting for the motion of the vehicle. Accordingly, the on-board computer system may use the corrected data to produce more accurate information characterizing the driving environment ahead of the vehicle. This more accurate information may be used to better estimate the motion of the vehicle in the future as the vehicle encounters that driving environment, which may improve the corrections that may be applied to the data corresponding to the forward-looking sensor at that time.
