Abstract

PURPOSE:To display the map of the periphery of the current position of a vehicle speedily by storing last map data as image data when the power source of the vehicle is turned off, and displaying the map based upon the storage contents when the vehicle power source is turned on. CONSTITUTION:A CPU 6 gathers map data on a constant range including the current position from a 1st storage medium 9 with the outputs of an azimuth sensor 1, a distance sensor 2, and a GPS device 3 in traveling, and displays them on a display device 11. When the vehicle power source is turned off, the last map data is stored as image data on a 2nd nonvolatile storage medium 10. When the vehicle power source is turned on, the image data on the medium 10 are displayed on a CRT 12 by a graphic controller 14. The on-off state of the power source is detected by a detecting circuit 17 and the output voltage of a regulator 18 is given a time constant to enable the storage on the medium 10 at the time of turning off the power source. Consequently, the map of the periphery of the current position is displayed speedily.
