DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation apparatus and a navigation apparatus for displaying a road network together with a detected position and other information on a display, and displaying predetermined information on a head-up display in conjunction with the display. The present invention relates to a recording medium that can be read by a computer.

[0002]

2. Description of the Related Art In recent years, on-vehicle navigation devices which detect the position of a vehicle and display a road map indicating the position on a display as a display means have been widely used.
Such a navigation device position detection method for a vehicle includes a GPS positioning method in which a GPS receiver measures the position using radio waves from a GPS (Global Positioning System) satellite, and a vehicle trajectory based on a travel distance and an azimuth of the vehicle. Self-contained navigation that detects the position of a vehicle.

At present, a map matching process for periodically comparing the position of a vehicle measured by the GPS positioning method with a road network recorded on a recording medium such as a CD-ROM or a DVD and correcting a deviation thereof. Based on the position obtained by this map matching process, a hybrid method of comparing the traveling trajectory of the vehicle calculated by self-contained navigation with the road network and correcting the deviation by the map matching process is mainly adopted. I have. In addition, route guidance along a traveling route set in advance is performed.

Conventionally, an aircraft uses a head-up display that projects an image of an instrument panel in the direction of a window so that a pilot can look at the instrument panel while looking out of a cockpit window. Recently, even a vehicle-mounted navigation device has been installed at a position on a dashboard where the driver can see the vehicle with a slight movement of his / her eyes while driving, and as shown in FIG. A head-up display 19 capable of displaying predetermined information on a translucent resin plate or a glass plate 24 or a part of a windshield has been put to practical use. The predetermined information is projected by a light beam having a wavelength reflected by the resin plate or the glass plate 24.

[0005] In a head-up display of an on-vehicle type navigation device, an information display area is very limited and a narrow range. Therefore, in order to output a large amount of necessary information, an information screen is displayed by time sharing like a picture-story show. To display a lot of navigation information within a certain time,
It is devised so that the driver can be notified.

[0006]

However, since a large amount of information is displayed on the head-up display like a picture-story show by time division, if the driver once overlooks the head-up display, the navigation device again uses the head-up display. Unless it was displayed, no information could be seen. The present invention has been made in view of the circumstances described above, and in the first to third inventions, the information displayed on the head-up display, which was overlooked, is displayed again on the head-up display by a switch operation and viewed. It is an object of the present invention to provide a navigation device capable of performing the following.

It is another object of the present invention to provide a navigation apparatus which can determine that information displayed again on the head-up display by operating a switch is the information displayed again. It is an object of the seventh invention to provide a navigation device capable of displaying the overlooked information displayed on the head-up display on the head-up display again by voice and viewing the information.

[0008] In the eighth invention, the navigation device that has read the information provides a recording medium on which the information that the driver overlooked and displayed on the head-up display is displayed again on the head-up display by operating a switch and can be viewed. The purpose is to do. In the ninth invention,
The navigation device that reads the information aims to provide a recording medium that allows the driver to determine that the information displayed on the head-up display again by the switch operation is the information displayed again. In the tenth invention, an object of the present invention is to provide a recording medium on which the information read by the driver, which has been overlooked and displayed on the head-up display, is again displayed on the head-up display by voice and can be viewed.
