Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an in-vehicle course guidance device capable of recording driving programs, and in particular is equipped with a map display section that projects a map to be superimposed on a display screen that plots a driving trajectory, and which can be used to control a course through a keyboard. The vehicle is equipped with a map film that has a magnetic recording section that can read/write information input by the vehicle, record map numbers corresponding to one's driving schedule, and sequentially project desired maps as the vehicle travels. This invention relates to an on-vehicle course guidance device that can record running programs.

Prior to filing the present application, the applicants of the present application developed an on-vehicle course guidance device as shown in FIG. The in-vehicle course guiding device is placed, for example, in front of the driver's seat, and as shown in Figure 1, it is equipped with a CRT display 1, and a direction sensor (not shown) and a speed sensor (not shown) that are separately mounted. A map sheet 3 drawn on, for example, a transparent film is configured to be attachable to and detachable from the front of the display screen, and a map sheet 3 drawn on, for example, a transparent film is configured to be able to be attached to and removed from the front of the display screen. The attached map sheet 3 is fixed by the fixing means 1a so that the traveling trajectory 2 is extended along a desired road on the map.

The above-mentioned in-vehicle course guidance device has one major feature and advantage in that it overlaps the display screen and the map and extends the driving trajectory along the road on the map. This can be expected as one direction for vehicle-mounted course guidance devices. However, in the case of the apparatus shown in FIG. 1, the map mounted to correspond to the display screen is present in the form of a map sheet, and is configured to be manually mounted and manually removed. For this reason, if, for example, while driving with one map sheet 3 attached, the driving trajectory progresses to the edge of the map and it becomes necessary to replace it with a new map, it is necessary to manually replace it. be. In addition, when performing this replacement, it is necessary to select a new map sheet to be replaced next from a large number of map sheets one by one, which is relatively troublesome.

The present invention aims to solve the above-mentioned problems, and uses a map display unit to project a map film onto a display screen by specifying a map number, and also provides a map suitable for one's travel schedule. The purpose of the present invention is to eliminate the above-mentioned complexity by arranging the number so that it can be programmed in advance via a keyboard. This will be explained below with reference to the drawings.

By using the in-vehicle course guidance device of the present invention, it is possible to record the map number according to the own driving course in advance via the keyboard and perform driving programming, and the map corresponding to each number. When the map is projected on the display screen, it becomes possible to record report information to be notified to the driver in correspondence with the map using the keyboard. Figure 2 shows the manner in which the above-mentioned recording or programming is carried out. When the driving course is determined, (1) the map display section is activated and a national map (block diagram) is first displayed on the display screen or Project via a map projection mechanism.

(2) As a result, a nationwide map (block map) as shown in Figure 3 is projected. For example, if you are planning to drive in the Tohoku region, the map number is "1".
Enter the key.

(3) This activates the map display section and projects a regional index map corresponding to the Tohoku region as shown in FIG.

(4) For example, if you plan to drive in an area corresponding to map number "30", use map number "30".
Enter the key. The map number "30" has the fifth
Maps as shown in the figure are associated with each other.

(5) The map number "30" is recorded, for example, in a magnetic recording section, which will be described later with reference to FIG.

(6) When the map corresponding to the map number "30" is projected later during actual driving, if it is necessary to notify the driver in response to the map, the key
Via the function keys on the board, notification information such as parking area rest, gasoline refueling, meal instructions, etc. can be recorded.

(7) Below, as long as it is within the range of the regional index map of the Tohoku region, for example, map number ``29'' that needs to be projected after map number ``30'' is key-input, recorded, and displayed as necessary. Enter and record the function keys. It goes without saying that it is also possible to project a regional index map or a national map (block map) as required.

The maps shown in FIGS. 3, 4, and 5 are stored one frame at a time on a map film 4 as shown in FIG. 7, for example, in the form of a reel. At the top of the map film 4, as shown in FIG.
