Abstract

PURPOSE:To prevent a car from running in a wrong way, by a method wherein a storing address information of a peripheral road map is previously recorded at a part of a recording medium of a road map, the information is detected, and if a car runs on a road running out of the map, a new map is automatically displayed. CONSTITUTION:A road map 2 on a long-sized rollform recording medium such as microfilms is projected on a display table 11 such as liquid crystal matrix panels, and simultaneously, a current position 14 of a car is displayed by a control circuit 10. Information, 3, 3', and 3'' on address regarding a map are previously recorded at peripheral parts of the road maps 2, 2', and 2'', and the address information is detected by a detecting means 4 to store it in a RAM6 through a CPU5. Meanwhile, a direction, in which a car run on a road running out of a map, is judged by means of signals from a bearing sensor 7 and a speed sensor 8, and the RAM6 is read based on the information to set a new map. This causes the rapid renewal of the correspondence of a car position to a map and prevents a driver from judging erroneously.
