<p>PURPOSE:To obtain a sensor transponder type car distance measuring device capable of obtaining not only the distance to counterpart car but also relative position relation easily. CONSTITUTION:Based on GPS information from a receiver for GPS information, an information processor 3 defines the absolute position of self-car from the longitude and the lattitude and simultaneously, the information processor, exchanging signal with counterpart car B, compares and calculates the absolute position of the self-car A and that of counterpart car B. Thus, the relative position relation of each other and the distance of the cars are detected.</p> |
