ABSTRACT:
Disclosed herein is a system and method for computer assisted driving of vehicles. The system disclosed herein provides an array of sensors positioned in the vehicles at strategic points for capturing vibrations and sound induced, when the vehicles move over pavement surfaces marked with predefined patterns of peaks and troughs. The sensors further measure frequencies of these vibrations. An onboard computer on the vehicle matches the captured frequencies and sound against pre-specified frequencies to obtain unique frequency signatures for the segment of the pavement traversed by the vehicle. Navigational data and geographical data associated with the unique frequency signature are used to provide assistance in driving of vehicles.
