    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: An apparatus to facilitate volume control for route aural guidance. When supplying a guidance voice to a loudspeaker 34a, a voice control section 30 disconnects the loudspeaker 34a from audio and outputs the guidance voice through the loudspeaker. A volume control screen is displayed on a display section 28 where the user adjusts the volume by touching the screen. When the voice control section 30 switches a signal to the loudspeaker 34a, a mute circuit 40a is operated to mute the voice output before the voice is output through the loudspeaker 34a. When the user terminates volume adjustment, the voice control section 30 outputs a voice for volume confirmation or check at the adjusted volume through the loudspeaker 34a. The user can check the adjusted volume at this time.

    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: There is provided a map data access method and device capable of reading out from a recording medium the map data requested by a navigation system and providing them to the system whether C language, etc. or JAVA (trademark), etc. is employed to constitute a processing program on the navigation system side. In the recording medium, the map data and a reading method of the data are recorded in pairs in a map data section and a method section, respectively. When a navigation function section requests the map data, a data access section reads out desired data in a method (program) read out from the method section according to a requested application programming interface (API). The data read out are supplied as a byte array object to the navigation function section.
