Arrangement for transferring information between a vehicle and one or more transmitters separate from the vehicle includes an antenna mounted on the vehicle and capable of receiving radio frequency waves emitted by the transmitter and containing information, a position determining device for determining the position of the vehicle, and a processor coupled to the antenna and the position determining device and arranged to analyze the waves received by the antenna, determine whether any received waves contain information of interest for operation of the vehicle based on the vehicle's position as determined by the position determining device, and extract the information of interest only from the received waves determined to contain information of interest. The information of interest may be information about the transmitter such as its location, speed, velocity, etc., or information relating to road conditions, weather and the like.

Communication method and arrangement

Method for transferring information between a vehicle and a transmitter in which a unique pseudorandom noise signal is transmitted by the transmitter in a carrier-less fashion composed of frequencies within a pre-selected band. Information is encoded in the noise signal relating to an identification of the transmitter and a position of the transmitter and the vehicle is provided with a device for extracting the information from the noise signal. The code to use for encoding the noise signal may be selected based on the position of the transmitter so that analysis of the code, or a portion thereof, provides an indication of the position of the transmitter. Information about accidents, weather conditions, road conditions, map data and traffic control devices and about errors in a GPS signal can also be encoded in the noise signals. The transmitter may be at a fixed location or in another vehicle to thereby enable vehicle-to-vehicle communications for the purposes of collision avoidance, intelligent highway applications and the like.
