    摘要: In a navigation apparatus for a vehicle, an entire route from a start point to a destination is determined and the vehicle is guided to the destination in accordance with the determined route. In the navigation apparatus, an entire route from a start point to a destination is first determined. Route determination is performed for a part of the entire route in accordance with a request of a user, and the entire route to the destination is determined again based on the result of the determination performed for the part of the entire route. The navigation apparatus has a first remaining-distance displaying unit and a second remaining-distance displaying unit. The first remaining distance display unit displays an arrow indicating the route and the remaining distance to an intersection. The second remaining-distance display unit deletes the display of the distance provided by the first remaining-distance display unit and changes the length of the arrow, which indicates the route, as the vehicle advances.

    摘要: A map display device is presented including an information memory device for storing map data, a display device for displaying a map based on map data stored in the information memory device, and a display control device, which has a coordinate transformation device for transforming coordinates on a curved plane into coordinates on a projected plane, for controlling the readout of map data from the information memory device and the map display on the display device. The display control device relates coordinates on the map to coordinates on the curved plane with respect to a coordinate transformation reference point, transforms coordinates on the curved plane into coordinates on the projected plane using the coordinate transformation device, and displays a map on the display device by using the coordinates transformed on the projected plane. Therefore, the device enables a driver to obtain the same sense of distance unaffected by the direction by using the present position. A map of the vicinity of the present position is displayed over a wide area.

    摘要: A navigation system for vehicles, capable of exactly and quickly showing guide information to a driver when two intersections to be negotiated are close to each other, is provided. A destination is input by an input part and a route to the destination is calculated from a present position of a vehicle, calculated by a present position determiner, by a route calculator included in a calculation section. The calculated route is stored in a route memory. A route guide controller included in the calculation section reads map information around the vehicle, stored in a guide information memory within a map information storage section and superimposes the map information with the present position of the vehicle, a traveling direction and the route stored in the route memory to display the superimposed information on a display. When the vehicle approaches the intersection, the screen is changed with an intersection map, but, when a next intersection map is required, the next intersection map is drawn on the back screen and is displayed by changing the two screens after the vehicle passes through the first intersection.

    摘要: Geographical, guide or search information and route information are stored in storage sections. An arithmetic section provides a route researching function with preference for the traveling direction of a vehicle. A route-calculating section is provided for re-calculating the route, and a route guide control system is also provided, inclusive of a route deviation-detecting section. The re-calculating section calculates either the shortest route from the point of deviation to the previous route or a new route to the destination. In case of the search of the shortest route to the previous route, the shortest route from the present location to the previous route is searched giving preference to the traveling direction, e.g. avoidance of a U-turn, on the basis of the search information relating to the immediate vicinity of the present location, so that the route to rejoin the previous route can be quickly calculated. In case of search of a new route, the whole route from the present location to the destination is searched, again giving weight to the present traveling direction, on the basis of the search information relating to the area between the present location and the destination, to guide the driver along a new route completely different from the previous one.
