Abstract
PURPOSE:To enable the reliable guidance of a vehicle along a route to the destination, by a method wherein a predetermined running route is converted into route data by an arithmetic means, the route data are compared with actual running data, and the result of comparison is reported. CONSTITUTION:A starting point, a predetermined passing point, etc. are designated by means of a light pen 12a on a map displayed in a display unit, and these inputs are read by a coordinates reading circuit 12b and converted into route data sequentially by an arithmetic circuit 13. The route data comprise the names of roads, the coordinates of turns, communicating roads, etc., and they are read from a road map data recording medium 6 and stored in a memory in a central processing unit 14. The processing unit 14 compares the route data with actual running data and reports the result by means of a composite voice of a voice ROM 14a and an arrow indication on a screen. By this method, a simple and sure route is set and a vehicle can be guided to the destination safely and without fail, while a driver is guided aurally for the route.
