Embodiment Construction

[0021] Embodiments of the present invention are described below with reference to the drawings.

[0022] FIG. 1 shows a block diagram of a navigation system 100 for a vehicle in an embodiment of the present invention. This navigation system 100 includes a position detector 1, a map data input device 6, an operation switch 7, a control circuit 8, an external memory 9, a display device (touch panel) 10, a voice input device (microphone) 11, a voice recognizer 12, a voice output A controller 13, a sound output device (speaker) 14 and a plurality of devices 15 for other purposes.

[0023] The navigation system 100 has a so-called route guidance function for displaying an optimal route from the current position to the destination when the destination position is received from the menu button displayed on the touch panel 10 or the operation switch 7 . This optimal route is calculated, for example, using Dijkstra's method or the like.

[0024] The position detector 1 includes a geo...

Abstract

A navigation system (100) for a vehicle, comprising a display (10), used for displaying the current position of the vehicle on an electronic map; The reference point (P) input by the content of (10); the point operation detecting means (8), for detecting the quantity of the reference point (P) input by the user; and the control means (8), for based on the reference point ( P) quantity, controls the navigation system (100) and other devices.

Description

field of invention [0001] In general, the present invention relates to a navigation system for a vehicle. Background technique [0002] Navigation systems used in vehicles provide services to drivers of vehicles to help them operate safely and efficiently. The navigation system utilizes the Global Positioning System (GPS) to detect the current location of the vehicle, and displays the detected location and route map on the display device, as well as the route map and route to the destination, for driver navigation. [0003] In recent years, a display device of a navigation system is equipped with a touch screen as disclosed in Japanese Patent Document JP-A-2004-184168. The touch screen displays a plurality of menu buttons, and those buttons combine functions such as a "zoom in / out scale" function, a "route display" function, and the like. [0004] However, the user of the navigation system must recognize the function of those buttons by observing the shapes and / or words di...
