摘要： When an update instruction to update “A” navigation map information and “B” navigation map information is inputted, a CPU initializes the storage area having stored therein no map information currently in use out of the two storage areas. The CPU then reads, from a CD-ROM, the latest version of the “A” navigation map information or the “B” navigation map information that corresponds to the map information currently in use, and stores it in the initialized storage area. The CPU then updates management information, starts use of the newly stored map information, initializes the storage area having stored therein the map information whose use is stopped out of the two storage areas, reads, from the CD-ROM, the latest version of the “A” navigation map information or the “B” navigation map information not currently in use, and stores it in the initialized storage area.

摘要： An information center generates packets of route guidance information, each corresponding to a prescribed road length of a recommended route. The information center may generate major guide point information and guidance information and transmit both to a vehicular apparatus. The vehicular apparatus provides guidance only for major guide points based on the received major guide point information if it cannot receive the guidance information. According to another aspect of the invention, if the end of a route segment which was the subject of the preceding route guidance information is on an expressway or toll road, guidance information for a preliminary route from that end to an escape position ahead on the expressway or toll road is first transmitted and then information for a remaining route, that is a segment of the recommended route having the prescribed road length minus the preliminary route, is then transmitted. If communication with the information center is lost, the vehicular apparatus performs guidance for the preliminary route to an interchange, for example, of the expressway using the preliminary route guidance information.

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 CPU of a navigation apparatus stores public keys to which priorities are set and which are published by an information distribution center in a public key storage section. The CPU of the navigation apparatus extracts an electronic signature of distribution data which is distributed from the information distribution center and verifies the electronic signature by using only ‘valid’ public keys among the public keys in order of the priorities. The CPU of the navigation apparatus determines that the distribution data is valid information which is distributed from the information distribution center when the electronic signature passes verification.

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.
