摘要： A position input system for a vehicular navigation apparatus includes an input unit for inputting a desired destination and a present position, a memory unit for storing desired destination information and map information, and a display unit for outputting the desired destination information and map information in response to input information from the input unit. The map information is indicative of intersections and a geographical point located between intersections and possessing useful guidance information. A desired destination and present position are capable of being inputted by setting the useful guidance information between a road leading to and a road leading from the geographical point. This makes it possible to enter position simply and accurately. Positions are precise since they are selected from pre-stored information relating to geographical locations. Vehicle direction can also be inputted in accurate fashion where parking lot exits and intersections are concerned.

摘要： A vehicular navigation apparatus, which is equipped with a help function, for outputting guidance information for travel to a desired destination includes an input unit having desired destination input means, present position input means and help function input means, a memory unit for storing desired destination information, and a display unit for outputting the guidance information in response to input information from the input unit, wherein the memory unit is provided with a non-volatile RAM, with necessary information being saved in an area of the non-volatile RAM when a help function is called by the help function input means. Help function items are provided for the following occasions: when the driver wishes to input or change a departure point and then depart from that point; when the driver wishes to change a desired destination while en route to a formerly set destination; when the driver strays off course while en route to a desired destination and cannot determine his present position without returning to the point at which the vehicle went off course; when a course cannot be travelled because of road construction or the like; when traffic becomes heavy and the driver wishes to change from one route to another to avoid congestion, and when the driver wishes to temporarily leave the course and then return to the course at the same point.

摘要： A navigation apparatus has an input unit (1), a CPU (2), a display unit (3) and a memory unit (4), the memory unit (4) being a memory such as a CD-ROM in which network data of geographical points, namely destinations and present locations, and information are stored in advance. Also stored are map data (10), an intersection list (11), a destination list (12), road data (13) and a region name list (14), etc. When a destination is designated by an input from the input means (1), the CPU (2) performs an exchange with a program, stored in a ROM (9a), in order to set information for travel to the destination by course exploration in accordance with each geographical point stored in the memory unit (4). This information is stored in a memory such as a RAM (9b). In an embodiment, the RAM (9b) is provided with a non-volatile area for storing departure-point data (east longitude, north latitude, etc.). When an input is made by a reset switch in entering a departure point, the data in this non-volatile area can be rewritten. Data written in are preserved until the reset switch is pressed again and a geographical point is entered. Data will not be erased even if an ignition switch is turned off.

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 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： 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 first external storage device which may be a CD stores data representing standard map of a particular area and that required for guidance, and a second external storage device which may be an IC card stores individual data which cannot be complemented by said data representing the standard map and said guidance data. Since the data is stored in both CD and IC card, the number of data can be reduced. This makes the operation simpler and enables a data that meets the demand of a user to be selectively supplied to the user. In consequence, guided navigation is made possible from any starting point to a destination, and data updating can be made relatively easy.
