| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Maintaining a safe following distance is very important for preventing collision accidents from happening. Usually relative position can be calculated from the absolute position exchanged via the inter-vehicle communications. In the urban area, however, due to multipath propagation, the non-correlated errors in the absolute position degrade the accuracy of relative position. Simply removing the reflected signals, the number of remaining signals may be insufficient for calculating positions. In this paper, we study the accuracy of relative position in the urban vehicular networks. The information of visible satellites and pseudo-ranges is exchanged among adjacent vehicles. The highly correlated signals received from the common satellites, including the reflected signals, are used to calculate the relative position. The simulation and experiment results confirm that the accuracy of relative positions among nearby vehicles can be effectively improved via the proposed scheme. | |
