Abstract

PURPOSE:To transmit various kinds of desired messages to a following car, etc., easily and clearly by making display control of a dot-matrix type electro- optical display by a controller according to the operation of a control panel. CONSTITUTION:A LED displayer 11 as a dot-matrix type electro-optical displayer is provided near a rear window in the interior of a car. Also, a display control controller 12 is connected to the LED displayer 11. In addition, an operating panel 13 such as a key board, etc., with which various kinds of information such as character information, its display form, display color, etc., to be displayed in the LED displayer 11 is inputted, a brake lamp 14, turn signal lamp 15, back-lamp 16, etc., are connected to the display control controller 12. Various kinds of information are displayed in the LED display 11 by, for example, interlocking with the lighting operation of lamps 14 to 16, and a desired message for a following car is displayed by the operation of a driver.

Description

[Detailed description of the invention] Industrial applications The present invention relates to an information display device mounted on an automobile.

BACKGROUND ART FIG. 5 shows the configuration of a rear lighting device that is standard equipment on a conventional automobile.6 As shown in FIG. 53 are provided in pairs. During braking, the brake lamp 51 lights up, and when the direction indicator switch is turned on, either the left or right direction indicator lamp 52 blinks, and when the vehicle is moving backward, the back lamp 53 lights up. In this way, even with the above-mentioned conventional lighting device.

Information necessary for vehicle operation can be transmitted to following vehicles by lighting or blinking each lamp.

Problems to be Solved by the Invention However, conventional rear lighting devices for automobiles are only capable of transmitting the minimum necessary information such as braking, direction change, and reversing to following vehicles.

The present invention solves the above problem, and aims to provide an information display device installed in a car that can transmit more information (message) than the conventional simple information transmission to a following vehicle. It is something.

Means for Solving the Problems In order to solve the above problems, the present invention provides a dot matrix type electric light indicator, signal input control such as a brake activation signal and a direction indicator activation signal, and display control of the electric light indicator. 6. Function: With the above configuration, the ffll1l can be displayed in text or graphic patterns in response to the operation of the rear lighting device of the automobile, and the following controller can be displayed by the driver's operation. Messages you want to convey to your car can be displayed in text or graphic patterns.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a schematic diagram showing the configuration of an information display device for use in an automobile, which is an embodiment of the present invention. FIG. 2 is an external view of the information display device for use in an automobile when it is installed in an automobile. FIG. 2 is a block diagram of the information display device mounted on the vehicle. As shown in FIGS. 1 and 2, an LED display ill as a dot matrix type electronic display is disposed near the rear window in the interior of the vehicle, and this LED display 11 is controlled by a display control controller 12. It is connected. The display control controller 12 has LE input from a keyboard or the like.
The 9-display control controller 12 is connected to an operation panel 13 for inputting character information to be displayed on the D display 11, its display form, and display color information, as well as a brake lamp 14, a direction indicator lamp 15, and a back lamp 16. As shown in FIG. 3, a manual input unit 46 has a function of accumulating information input from the operation panel 13 and notifying the scheduling unit 47, a brake lamp switch 41, a back lamp switch 42, and a direction indicator lamp switch 43. and a sensor input section 48 connected to a pulse signal input terminal 44 indicating the speed of the automobile, a notification signal from the manual input section 46 and a notification signal from the sensor input section 48 are inputted, and a display is output according to each request. a scheduling unit 47 that performs exclusive control of the scheduling unit 4;
The bit image data output from the 0 display output unit 49, which is provided with a display output unit 49 that develops the display information into a bit image according to instructions from 7, is
It is displayed on the ED display 11.

Next, the operation of the above embodiment will be explained. Operation panel 1
3 is held by the manual input section 46, and the display information is held by the scheduling section 47.
will be notified as a display request. The scheduling unit 47 responds to the request.

A display request notification is sent to the display output unit 49, and the display output unit 49 expands the display information into a bit image and outputs the result to L.
Output to the ED display 11. Further, the display output unit 49 performs a flowing character display, a blinking display, etc. in response to the display request. When the brake lamp switch 41 is turned on, the scheduling unit 47 receives a single request from the sensor input unit 48 to notify the scheduling unit 47 of a request to display a stop message, and the scheduling unit 47 changes the content that had been displayed up to that point. If the request is approved, the display output unit 49 is notified to display a stop message.

Similarly, when the back lamp switch 42 is turned on, a reverse message is notified. When the direction indicator lamp switch 43 is turned on, a right or left course change message is notified. However, the current speed is determined from the speed pulse input from the speed pulse input terminal 44, and if the speed is less than a predetermined speed, a right turn or left turn message display request is notified, and if the speed is higher than that, a message display request is sent. notifies you of a lane change (right or left) message.

In this manner, according to the above embodiment, the user can input a desired message to the LED display 11.
In addition to being able to display accurate messages in accordance with the movements of the vehicle during operation, it is also possible to immediately display accurate messages that match the movements of the vehicle, which has the effect of communicating intentions to following vehicles and ensuring safety.

In addition, in Fig. 4, (a) is the stop message, (b)
) is a right turn message, (C) is a reverse message, (d)
and (e) shows an example of a manually entered message.

Effects of the Invention As described above, according to the present invention, by controlling the electric light display with a controller and displaying various messages, it is useful for ensuring safety in the operation of a car, and
By operating the operation panel, it is also possible to send messages to following vehicles.
