摘要： A route guidance section compares the current position provided by a current position determination section and the route provided by a route calculation section for detecting an off-route condition. When the off-route condition is detected, a researching key as well as the route and current place is displayed on a display section. When the researching key is touched, a search is again made for a new route from the current position to the destination. Then, route guidance is again started in response to the researching result. When the researching key is not touched, the route and current place continue to be displayed while the vehicle carrying the apparatus travles off route, thereby efficiently preventing the apparatus from executing unnecessary researching when the driver drives the vehicle off route on purpose.

摘要： A vehicle navigation system realizing a discrete display of the present position of a vehicle during a period from when the vehicle reaches a predetermined distance before an intersection until the vehicle passes the intersection. Especially, in a zone a short distance before the intersection, the present vehicle position mark is fixed at the center of the displayed intersection until the travelling direction of the vehicle is changed. Thereby, even when the accuracy of monitoring of the present position is relatively low, misindication, such that the present position is displayed as if the vehicle has passed straight through the intersection in spite of not having actually reached the intersection, is avoided.

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.

摘要： A navigation system for use in a vehicle including a route-calculating section and a route guide control section. The route-calculating section searches for an optimum route according to conditions set for the search. The guide control section provides displays necessary to guide the driver of the vehicle, and guides the driver by speech. This guide control has a landmark name-setting section which sets the names of landmarks according to information about the landmarks, the information retrieved from a guidance information storage section according to information about the present position from a present position-determining section. A display section displays a whole route map indicating the selected route according to instructions from the route guidance control section. At the same time, the names of the landmarks are presented on the display section. When the navigation system guides the driver to a destination via a tollway such as a toll highway, the name of an entry/exit interchange connecting to the highway is displayed. This permits the driver to take a familiar route up to this interchange.

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.
