  • Patent number: 4812845
    Abstract: A running guide system for an automotive vehicle planned for running in a sightseeing area or the like. Special running data including right or left turn, passage through a tunnel, running in a predetermined direction and passage on a slope are stored in a cassette tape together with distance data representing the distance from a start point in the form of a plurality of check point data. By collation of the running distance data actually measured and the special running condition data with the stored data, the automobile is guided audibly or visually. Geographical data or sightseeing data are also recorded in the cassette tape and reproduced in voice from time to time. When the automobile is displaced from the planned running route, an alarm is issued. When the automobile is restored to the planned running route, the planned running guide is restored.
