    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 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: Navigation data (26) are generated by performing course exploration up to a destination using path data (26), which include information relating to intersections and road information, in response to input of the destination. Course guidance to the destination is provided while present-position pursuit (37) is performed. Course guidance at an end-point of a present-position road is outputted using guidance information for travel to a destination at every intersection obtained from the road network data (26) by course exploration. At an intersection, a road in a direction of travel is recognized by the present-position pursuit means (37), present position on this road is kept track of and the end-point intersection of the road is recognized. Recognition of the travelling direction is performed at the end-point intersection of a road between intersections, and guidance to the next end-point intersection is outputted with the road in the travelling direction serving as a present-position road, whereby course guidance is performed repeatedly at every intersection up to the destination. In course exploration, a road in the direction of travel leading to the destination is set with regard to each intersection. Therefore, if an intersection and the road in the travelling direction thereof are recognized, it is possible to provide course guidance from the end-point intersection of the road in the travelling direction to the destination.

    摘要: In a navigation system, during navigation between guidance intersections A and B, a next named intersection C is displayed along with the distance remaining until the named intersection B is reached. After the vehicle has entered the distance error correction range, illumination color of the display of the next named intersection C is changed into, for example, red. If a corresponding portion of the display screen is touched at the time of passage though the intersection, a distance error is corrected. The invention thus makes it possible to readily correct distance errors with accuracy. Even during navigation along a straight road, distance correction can be performed at specific intersections. The invention also makes it possible to track the present position with accuracy by increasing the frequency of distance error correction.

    摘要: A navigation system calculates a route from a present position of a vehicle to a destination and provides guidance based on the calculated route. When the vehicle is within a given distance from a next approaching branch point requiring guidance, branch points existing within a given distance from next approaching branch point are determined and direction information for the branch points is acquired. The acquired direction information is compared with direction information at the next approaching branch point, and a common direction information is displayed based on the result of the comparison. Also, the navigation system according to the present invention detects a name of an interchange where the vehicle is to exit from the course and a distance to said interchange based on the present position of the vehicle in case the road where the vehicle is currently driven along is an expressway or a toll road. The navigation system according to the present invention calculates a route from the present position to the destination and properly calculates and provides guidance for the expected time of arrival at the destination as the vehicle moves.

    摘要: Even when the present position does not exist on a guide road after deviation from an established guide route, a guide road is identified and a more advantageous route is identified. Furthermore, only a minimum amount of required data are displayed on the map picture. The searching again is executed by taking the direction of progress of the car into consideration. Street names of the roads are displayed on the guide map, enabling a guide route to be easily recognized. A particular area is specified by a postal code number or by a telephone number, and the streets or the facilities in the specified area are displayed. This makes it easier to search the destination.
