Hereinafter, an in-vehicle information display device and an in-vehicle information display method according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a vehicle information display device 10 according to an embodiment of the present invention.

In Fig. 1, the vehicle position detection unit 11 that detects the position of the vehicle is detected by a positioning system using artificial satellites such as GPS, and the self-positioning is detected by an angular velocity sensor, acceleration sensor, vehicle speed sensor, etc. Can be.

The communication unit 12 is a communication module installed to transmit and receive data from outside the vehicle.It uses a communication method using a public communication line used for mobile phones, etc. Or a communication method that acquires information based on information multiplexed in FM broadcast, AM broadcast, and TV broadcast.

The information acquired by the communication unit 12 includes a label and other vehicle information, which are respectively stored in the label position, the information acquisition unit 13 and the other vehicle position, and the information acquisition unit 14, respectively. Is stored.

A label is a memo in which a message is written together with location information, and generally leaves a hobby and preference of a writer as a message. For example, when a skateboard enthusiast invites a skateboard enthusiast to join, leave a message on the street corner saying, “Skaters gather! You can leave a message at the same time.

These labels are honest and tasteful, so they are a letter-like image, but can also be used as general advertisements for the purpose of notifying the general public. It may be used to notify the driver or to notify the driver of caution in places where fatal accidents occur frequently.

In other words, “〇 x restaurant's tonkatsu is very delicious!”, “□ パ Departure, summer bargain is on!”, “Currently, ◎ □ street is currently holding the Bon Dance Festival. Attention! " Although information on such labels and other vehicles is not shown, the user can select the content of the label acquisition. The label and the information of the other vehicle acquired as described above are subjected to drawing processing by the drawing processing unit 15 together with the own vehicle position obtained by the own vehicle position detection unit 11.

The drawing processing section 15 uses the position information of the label and other vehicles, and performs drawing processing based on the relationship with the own vehicle position. The position of the vehicle is located in the center of the lower part of the screen.

At this time, the shape of the road may be drawn, but it is preferable to delete unnecessary roads, buildings, intersection names, etc. in order to make it easy to recognize the label of the other vehicle to be identified. When the label is close to the vehicle position, the information registered in the label is read from the label position / information acquisition unit 13 and a drawing process is performed to display the message.

5 o

In other words, labels are divided into simple drawings that display relative positions and detailed drawings that display message contents at the same time, based on the positional relationship with the vehicle position. The drawing created by the drawing processing unit 15 is displayed on the display unit 16.

In addition, the drawing processing unit 15 draws the change position at which the simple drawing is changed to the detailed drawing at the same time as the own vehicle position, thereby making it easy to recognize the change in the label information. In addition, in the label drawing process, the positional relationship between the own vehicle position and the label position, which determines whether to use the simple drawing or the detailed drawing, is generally determined by the distance. And the time required for the vehicle to reach the label may be calculated, and the time may be determined based on the calculated time.

Next, FIG. 2 shows an in-vehicle information display method according to an embodiment of the present invention.

In FIG. 2, a label / other vehicle extraction setting S1 and an information acquisition timing setting S2 are performed as initial settings. In other words, in the label / other vehicle extraction setting S1, the information acquired by the label position / information acquisition unit 13 and the other vehicle position / information acquisition unit 14 is set according to the user's taste and preference. For example, as a label extraction setting, users can freely select and register items of particular interest, such as “skateboard”, “pagen”, and “festival”.

In addition, other vehicle extraction settings are focused on users such as emergency vehicles (ambulances, fire trucks, police cars with red lights, etc.), trailers, buses, Mr. 〇〇's car, and □□ your car This sets the vehicle and vehicle type. In order to obtain such information, the position of each vehicle must be transmitted by itself.This is achieved by transmitting the vehicle position by the vehicle position detection unit 11 to the outside using the communication unit 12. It can be easily realized.

In addition, the information acquisition timing setting S2 is for setting the timing of whether the label is displayed as simple drawing or detailed drawing. For example, the position of the label is 500 m with respect to the own vehicle position. If you want to switch from simple drawing to detailed drawing when it comes to the foreground, set the setting to “500 m”.

If the time for the vehicle to reach the label is set to `` 5 seconds '', the arrival time is calculated based on the current speed of the vehicle and the distance from the vehicle to the label. You can do it. The above is the initial setting, and it is possible to make these settings during driving, but in general, it is necessary to do it before driving. Is desirable.

Next, when the vehicle starts traveling, the communication unit 12 starts communication to acquire the label of the area that needs to be displayed on the display unit 16 and the other vehicle with respect to the own vehicle position (label, other vehicle position). Z information acquisition S 3).

At this time, only the user's hobbies and preferences may be acquired according to the label and other vehicle extraction setting S1 set in the initial setting, but if the information acquiring capacity of each acquiring unit is sufficient, All data may be acquired and stored.

Next, based on the relationship between the information thus obtained and the position of the vehicle, it is determined whether or not a label exists at the information acquisition timing set in the initial setting (S4). If there is no label, the position of the vehicle is determined. The position of the label for the other car corresponding to the vehicle is displayed by simple drawing (S5, Fig. 2).

As shown in FIG. 3, the own vehicle position 21 is positioned at the lower center of the screen, and the information acquisition timing area 22 is drawn as if this own vehicle position 21 is drawn in a concentric circle. The mark indicating 1 has a large oval shape, the mark indicating the other vehicle 23 has a small oval shape, and the mark indicating the label 24 has a ★ mark.

The other vehicle 23 and the label 24 are arranged on the bird chart with respect to the own vehicle position 21 and the size is determined by the relative position with respect to the own vehicle position 21. 24 and other vehicles 23 will gradually increase in size. This state is shown in FIG. Fig. 4 shows a situation in which the label 24A approaching the own vehicle and the other vehicle 2.3A increase in size.

In addition, based on the relationship between the acquired information and the position of the own vehicle, it is determined whether or not there is a label at the information acquisition timing set in the initial setting (S 4). Is displayed on the display unit 16 as a detailed drawing together with the label located at (S6). This state is shown in FIG.

In Fig. 5, when there is a label 24A in the information acquisition timing set in the initial setting, the information of the label 24A, "Skaters gather! Sliding at 3:00 on holidays" is displayed as detailed drawing. Displayed in Part 16

Then, on the screen other than the detailed drawing of the displayed label, other vehicles and other labels are displayed. Display a simple drawing of the file. It is considered that the time required to display the detailed drawing is sufficient for the user to recognize and understand the contents. Therefore, it is usually about 15 seconds, and such a detailed drawing display time can be set arbitrarily.

According to the above, it is possible to safely provide information on labels and information on other vehicles that match the tastes and preferences of the user when driving, and to display the specific contents of the labels. is there.
