DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle information display device which is used for a vehicle navigation device and displays information such as vehicle maintenance.

[0002]

2. Description of the Related Art Various information devices for displaying vehicle maintenance have been proposed. For example, there is an information display device as disclosed in Japanese Patent Application Laid-Open No. 63-245798. This information display device displays the contents of maintenance such as engine adjustment and oil change and the arrival of maintenance time.

[0003]

However, in the above-described configuration of the prior art, the user can know the necessity of the contents and timing of maintenance by displaying the information. However, it was not sufficient in terms of presentation of service information, and there was a problem. Because the general user is not fully proficient in maintenance technology, and rarely possesses maintenance tools,
Eventually, the usual pattern is to bring a vehicle to a service factory that performs maintenance services or similar facilities, and then receive maintenance. In particular, the driver of a commercial vehicle is also switched, often unspecified,
In addition to daily driving in a fixed area, there are many cases where you drive irregularly throughout the country.To receive maintenance on unfamiliar land, make it easy to find the location of the maintenance service facility. There was a strong demand for it.

[0004] As described above, in the display contents of information according to the prior art, there is no information on "location, location" as to which service factory should receive the service for the maintenance for which the warning was displayed, and the user's information is not displayed. From a standpoint, the information was not satisfactory. That is, the way of presenting information according to the prior art is an information display that focuses on the holding of the car, thinking about the car, and is a warning content that only warns that it is necessary for the hardware of the car. However, it did not present information from the user's point of view, which provided guidance for solving the problem.

[0005] Furthermore, a navigation device has an original function of being excellent in guiding to a geographical point such as "location, location", and displays the above-mentioned service factory only when the user is unknown. Or is expected to guide. Such a navigation device is characterized by excellent guidance information by route guidance, but cannot be guided by the device at the time of vehicle maintenance. Was not fully satisfactory.

The present invention solves the above-mentioned conventional problems. When the maintenance time comes, the display of information on service facilities and the like that can receive maintenance is automatically displayed on a map screen of the navigation. It is an object of the present invention to provide a vehicle information display device which can display the information and improve the convenience of the user.

[0007]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a means for detecting a traveling distance of a vehicle and a certain point in time of a target traveling distance to be reached by the vehicle in the future. A means for setting and inputting a target mileage value, and a means for a user to create a unique landmark marker such as a name, a symbol, etc., and to set and input the image to be projected to an intended point on the navigation map screen , Detecting that the vehicle has reached the target mileage ,
Means for projecting the marker on the navigation map screen.

[0008] With this, when the maintenance time comes, the display of information on the service facilities and the like that can receive the maintenance can be automatically displayed on the map screen of the navigation, thereby improving the user's convenience. Thus, a vehicle information display device capable of performing the following is obtained.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
A description will be given based on the drawings .

FIG . 1 is a block diagram showing a schematic configuration of a vehicle information display device according to an embodiment of the present invention.

The traveling distance of the vehicle A is measured by measuring means installed on the vehicle A itself, and a numerical value is displayed on a odometer (trip meter) of an instrument panel in a dashboard. In the apparatus of the present invention, the detection of the traveling distance of the vehicle A is performed by branching the signal to the odometer described above. This advantage is caused by the difference in the measuring means when the measuring means is separately provided. There is no data difference. In addition, there is a cost advantage compared to a case where a measuring unit is separately provided.

In FIG. 1, a mileage detecting means 1 branches a signal to the odometer of the vehicle A itself and detects it, and the detected signal is applied to a data processing means 5 through a mileage signal input section 1a. You.

The target mileage input means 2 displays a screen 11 for setting maintenance shown in FIG. The setting location in the screen 11 can be input in an interactive manner by using the input keys 2a. As shown in FIG. 2, the content of the input setting by the target travel distance input means 2 is a maintenance time 11a and the other is a maintenance content 11b. maintenance
Since the timing generally depends on the traveling distance of the vehicle A, the present invention conforms to that. There are two ways to express this travel distance value. The first method is to match the displayed value of the odometer of vehicle A, "How many kilometers the vehicle's odometer displays?" This means "(count value of mileage after running)-(count value of mileage before running)", and any method may be used. The maintenance contents 11b include oil change of the vehicle, engine adjustment, tire check, and the like. The configuration of the key input unit 2a may be either built into a part of the housing constituting the display screen or a form of a separate remote control key. The signal input here is provided to the data processing means 5.

The landmark information input means 3 first creates a marker as a landmark and positions and sets an intended point on the map screen. The name, design, etc. of the marker are created and input using the key input unit 3a in order to create a visual expression. For example, a car design meaning a car repair shop and a factory name are created and input. Pattern,
There are several methods for creating a visual expression such as a character. One of the methods is to draw a pattern, a character, and the like by accumulating dots in a dot font system. Other methods include reading the handwritten data on the keypad using the handwriting input method, selecting from several ready-made designs previously input to the device, or selecting from character strings. There are ways to do that.

The map data storage section 4a of the storage means 4 stores digital map information data, and the landmark information storage section 4b
Stores the marker of the mark information created by the mark information input means 3. The signal from the storage means 4 is transmitted to the data processing means 5
Is given to

When the landmark information processing section 5a of the data processing means 5 confirms that the distance signal given from the running distance detecting means 1 matches the target distance value set by the target running distance input means 2, the mark information processing section 5a of the storage means 4 A data process is performed for overlaying the mark information stored in the mark information storage unit 4b on the map data stored in the map data storage unit 4a. The drawing control unit 5b performs a process for displaying information processed by the mark information processing unit 5a on the screen of the display unit 6.

The operation of the above configuration will be described below with reference to screen display examples shown in FIGS. 3 to 5 and a flowchart shown in FIG.

First, the engine key of the vehicle A is turned on and the power supply of the navigation device is turned on (step S1). Usually, the power supply of the navigation device is vehicle A
The engine key of the vehicle A is turned on, and the power of the navigation device is turned on while the power of the engine of the vehicle A is turned on. When the vehicle A travels, the traveling distance detecting means 1 detects the traveling distance (Step S2). The landmark information processing unit 5a of the data processing unit 5 calculates a target for maintenance in which the cumulative traveling distance of the vehicle A is set by the target traveling distance input unit 2 from the distance signal sent from the signal input unit 1a of the traveling distance detection unit 1. It is determined whether or not the travel distance has been reached (step S3). If the target travel distance has not been reached, a navigation map 12 as shown in FIG. 4 called from the CD-ROM is displayed on the display means 6 (step S4). If the target travel distance has been reached, a maintenance notification screen 13 showing the arrival of the maintenance time and the contents of the maintenance as shown in FIG. 3 is displayed on the display means 6 to notify the user (step S5). After the user recognizes that the maintenance time has arrived and the contents of the maintenance, "clear the screen display" in the lower right of the screen
The screen display is terminated by inputting the cursor 14 of the navigation map 1 (step S6), and the navigation map 1 called from the CD-ROM is displayed on the display means 6, as shown in FIG.
The landmark marker of the maintenance factory, which is created by the landmark information input unit 3 and is stored in the storage unit 4 in accordance with the screen 2 (step S7).

As described above, according to the embodiment, the convenience of the user can be improved, and the navigation apparatus can display additional information on the vehicle in addition to the display of the original map screen. So the utility value is increased. Also, from the standpoint of service improvement, entering the network location of each site of the company's factory will lead to solicitation for the next maintenance, and from the viewpoint of sales activities, the utility value is high, and the effect is high. It can be said that it is big.

[0020]

As described above, according to the present invention, it is possible to automatically inform a user of the time of maintenance such as oil change of a vehicle, engine adjustment, tire check, etc. and to receive the maintenance service at the same time. By showing the location of facilities such as service factories on a map, from the user's point of view, not only can the maintenance management of vehicles be reasonable, but also the location of service factories etc. can be guided by navigation. And convenience is enhanced. In particular, in the case of a business vehicle where the vehicle is used in a wide area nationwide and unspecified drivers alternately use the same vehicle, it is not necessary to return to the home base every time the maintenance time arrives. Also make it easier to get maintenance on the go. That is, the trouble of searching for an appropriate service factory in an unfamiliar land can be eliminated, which is more convenient.
