Embodiment Construction

[0035] One embodiment of the present invention will be described below.

[0036] Embodiment 1

[0037] Fig. 1 is a block diagram showing the configuration of a vehicle-mounted navigation system according to Embodiment 1 of the present invention.

[0038] In Fig. 1, the vehicle-mounted navigation system consists of a current position detection unit 1, a map information unit 2, a communication unit 3, a communication interface 4, a memory unit 5, a memory 6, a graphics IC (integrated circuit) 7, a monitor 8, An audio unit 9 , a remote controller unit (hereinafter referred to as “remote controller”) 10 , a light receiving unit 11 and a CPU (central processing unit, processing unit) 12 are constituted.

[0039] The current position detection unit 1 detects the current position of the vehicle. The current position detecting unit 1 has a GPS (Global Positioning System) receiver 1a, a receiving antenna 1b, a gyro 1c, and a vehicle speed pulse generator 1d.

[0040] The GPS receive...

Abstract

The invention is to operate two or more different functions on one processor (CPU) and to simultaneously display an image of each function in divided multiple screens. The CPU 12 performs route guide control processing for retrieving a route from a present position to a destination based on a present position detection part 1 and a map information part 2, and displaying a route guide on a monitor 8. A processing for displaying images based on one or two or more different names of functions designated by a remote control 10 from function of communicating or acquiring information through a communication part 3, and functions relevant to the route guide control such as position retrieval function and point registration function on the monitor 8 by one screen or divided multiple screens is performed by this CPU 12 alone.

Description

technical field [0001] The invention relates to a vehicle-mounted navigation system which implements two or more functions on one processor and simultaneously displays the images of these functions with split multi-screens. Background technique [0002] On the Internet, a large amount of information related to sightseeing facilities, restaurants, hotels, etc. is provided, and in some cases, more detailed map information than that provided by a common navigation system is provided. [0003] In order to make full use of such information, conventional vehicle-mounted navigation systems set a destination based on map information such as addresses obtained from the Internet, search for a route to the set destination, and perform route guidance. Such in-vehicle navigation systems include, for example, the following systems. [0004] As one of the conventional systems, an Internet terminal obtains map information as homepage information through a back-end server through Internet c...
