Description

Safety message and advertisement transmission system using vehicle display devices

[0001] The present invention relates to a system for transmitting safety messages and advertisements using a vehicle display device, and more particularly, to a system for transmitting safety messages and advertisements using a display device installed toward the rear of a vehicle to transmit messages to other vehicles.

[0002] Traffic disputes between drivers have been on the rise recently. In situations requiring communication between drivers, such as cutting in, abrupt stops, or sudden braking, simple flashing lights and left / right turn signals are not sufficient to accurately convey the intent of drivers. To address this, various attempts are being made to display drivers' messages through displays installed in vehicles.

[0003] Additionally, in the automobile signage industry, advertising using displays is being implemented using various regulatory exceptions.

[0004] For example, displays are installed inside and outside of cars to display advertisements or safety messages appropriate to the driving situation.

[0005] However, if you take action to display a specific message while driving, it may cause an accident due to careless driving, and the glare of the display may disturb the driving of surrounding vehicles.

[0006] Accordingly, there is a need for control technology and methods that can safely transmit messages or advertisements using the displays of these automobiles.

[0007] The present invention aims to provide a system for transmitting safety messages and advertisements using a display device installed toward the rear of a vehicle and transmitting messages to other vehicles.

[0008] A system for transmitting safety messages and advertisements using a display device installed to face the rear of a vehicle and transmitting messages to other vehicles according to one feature for realizing the above-described object of the present invention comprises: a display unit installed to face the rear of a vehicle; an operation unit for receiving a user's selection of a message to be displayed on the display unit; and a control unit for transmitting the message selected from the operation unit to the display unit; and a commercial server for providing commercial information to the vehicle display unit.

[0009] At this time, a mobile terminal may be further included to link the commercial information provided from the commercial server to be displayed on the vehicle display device.

[0010] In addition, the commercial server may include an information collection unit that receives driving information of the vehicle from the mobile terminal; an advertisement provision unit that determines commercial information to be displayed on the display device based on information collected by the information collection unit; and a revenue management unit that performs billing for a supplier who provides the commercial information and revenue settlement for a user of a vehicle display device on which the commercial information is displayed based on whether or not the commercial information is displayed.

[0011] Meanwhile, the information collection unit receives the driving route of the vehicle and the current driving status of the vehicle in conjunction with a driving route guidance application running on the mobile terminal, and the advertisement providing unit can select and provide an advertisement message provided by an advertisement provider based on the current driving status of the vehicle and the driving route.

[0012] In addition, the revenue management unit may provide a portion of the advertising revenue to the driver of the vehicle based on the display location and number of times the provided message is displayed.

[0013] According to a system for transmitting safety messages and advertisements using a display device according to the present invention,

[0014] First, it can contribute to improving traffic flow and safe driving by conveying the driver's driving intentions through the display panel installed at the rear.

[0015] Second, the display panel is transparent, so it does not obstruct the driver's rear view even when installed on the rear window of a vehicle.

[0016] Third, it does not hinder safe driving because it allows you to send the desired message through simple operations.

[0017] Fourth, the implementer of the present invention can obtain additional profits through the provision of commercial information in addition to profits from the sale of vehicle display devices.

[0026] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings. Please note that, where possible, identical components are represented by identical reference numerals throughout the drawings. Furthermore, detailed descriptions of well-known functions and structures that may obscure the gist of the present invention will be omitted. For the same reason, some components in the attached drawings are exaggerated, omitted, or schematically depicted.

[0027] Before describing a safety message and advertisement transmission system using a vehicle display device according to the present invention, a vehicle display device (1000) will be described in detail.

[0028] FIG. 2 is a block diagram of a vehicle display device for implementing the present invention, FIG. 3 is a drawing illustrating a first button module according to one embodiment, FIG. 4 is a drawing illustrating a second button module according to one embodiment, FIG. 5 is a drawing illustrating a display unit according to one embodiment, FIG. 6 is a drawing illustrating a first button module according to another embodiment, and FIG. 7 is a drawing illustrating a first button module according to yet another embodiment.

[0029] Referring to FIGS. 2 to 7, a vehicle display device (1000) for implementing the present invention includes a display unit (100), an operation unit (200), and a control unit (300).

[0030] The display unit (100) is preferably formed on a transparent substrate and is arranged to face the rear of the vehicle. It includes a plurality of light-emitting elements arranged in an M x N array. However, depending on the implementation conditions, it is also possible to implement it using a general LED panel as illustrated in FIG. 1. For example, when applied to a cargo vehicle, etc., since a transparent panel does not have an advantage, the display unit (100) may be implemented using a conventional LED panel for reasons such as manufacturing cost / durability.

[0031] The display unit (100) controls the operation of light-emitting elements arranged in series, including a control data input port. At this time, the M x N array can be implemented as 16 x 64 to 256 x 512, etc., for visibility. A message is displayed in text format through the display unit (100).

[0032] Although not shown, the display unit (100) measures external illuminance through an illuminance sensor equipped in the display unit itself or an illuminance sensor equipped in the vehicle, and can selectively implement a display with a brightness of 10 cd / m2 to 2,000 cd / m2 depending on the external illuminance.

[0033] At this time, the light sensor receives the light as a single sensor or a surface receiving sensor, and the display unit (100) can adjust the brightness as needed to a specified brightness according to the received external light.

[0034] The display unit (100) can adjust its brightness according to the surrounding brightness, thereby improving visibility. In particular, when entering a tunnel, the brightness of the display unit (100) can be immediately lowered, thereby minimizing any obstruction to the view of the driver of the vehicle behind.

[0035] The control unit (200) receives a message from the user to be displayed on the display unit (100).

[0036] The messages to be displayed on the display unit (100) are about situations that occur while driving, and examples thereof include “yield,” “thank you,” “dazzle,” “safe distance,” “sorry,” “scheduled to stop,” and “stopped.”

[0037] For example, "yield" can be used to request more space from the vehicle behind you when changing lanes. "Thank you" can be used when the vehicle behind you slows down to provide more space when changing lanes.

[0038] Messages can be displayed as a single word or as a short sentence consisting of several words. Furthermore, messages can be customized by the user.

[0039] The control unit (200) is a physical interface that receives user input, and the control unit (200) is implemented in a form that has buttons that allow the user to select a message that he or she wants to display on the display unit (100), such as “yield,” “thank you,” “dazzle,” “safe distance,” “scheduled to stop,” or “stopping.”

[0040] Depending on the embodiment, the “button” may be a physical button or implemented as a touchscreen.

[0041] The control unit (300) transmits a message selected from the operation unit (200) to the display unit (100). The control unit (300) includes a driver circuit for electrically driving the display unit (100), and may further include a logic module for driving software for customizing the message content, if necessary. In addition, the control unit (300) may further include a communication module for linking with the user's smartphone.

[0042] The control unit (200) may be implemented in a form that is mounted on the dashboard or sun visor of the vehicle, or may be implemented in a form that is mounted on the steering wheel. Alternatively, it may be implemented in a form that is mounted on the rearview mirror as shown in Fig. 6.

[0043] In the present embodiment, the operating unit (200) includes a first button module (210) that is mounted on a dashboard or sun visor of a vehicle for convenience of operation and safety of driving, and a second button module (220) that is mounted on a steering wheel. The operating unit (200) can be implemented using only one of the first button module (210) and the second button module (220), but it is preferable to have both modules for safe operation.

[0044] The first button module (210) has a plurality of message transmission buttons (B1, B2, ...) corresponding to each message.

[0045] When implemented in the form of physical buttons, the first button module (210) has a number of buttons corresponding to the number of messages. As shown in the example, the number of message transmission buttons (B1, B2, ...) can be implemented at the level of 1 to 30.

[0046] The message sending buttons (B1, B2, ...) display messages to be displayed on the display unit (100). In the case of physical buttons, the "message" is printed on the button surface.

[0047] When a user selects (i.e., presses) a specific message sending button (e.g., “Yield”), a message corresponding to that button is displayed on the display unit (100).

[0048] Corresponding content to the "Yield" button could be "Please yield", "Please put me in", etc.

[0049] The second button module (220) has a simplified number of message transmission buttons so that it can be mounted on a steering wheel, but the basic operation method can be implemented in the same manner as the first button module (210).

[0050] Meanwhile, selection of the message sending button (B1, B2, ...) can be done not only by the user's hand but also by voice recognition.

[0051] This is a description of the basic embodiment of the control unit (200), and from below, the automatic message selection function for safe driving will be described.

[0052] Although the user can intuitively operate the device by directly selecting and pressing the button of the first button module (210) or the second button module (220), it may distract the user's attention in some cases.

[0053] In this embodiment, the operating unit (200) can provide an alarm by lighting up a message transmission button corresponding to the current driving state of the vehicle in conjunction with the driving state of the vehicle.

[0054] For example, the control unit (200) can detect a change in acceleration of the vehicle and display a light on a message transmission button corresponding to “sorry” when a sudden stop occurs.

[0055] Users can quickly and visually identify the illuminated buttons, minimizing driver distraction.

[0056] As another example, the control unit (200) may be linked with a navigation and vehicle information system (AVN SYSTEM) to display a light on a message transmission button corresponding to "scheduled to stop" when the vehicle arrives at its destination. As another example, when the user operates a lane change signal (i.e., a blinker), the message transmission button corresponding to "scheduled to stop" may be displayed on a light.

[0057] Depending on the embodiment, the operating unit (200) may be directly linked to each of the vehicle's suspensions, and the operation related to the linkage may be performed by the control unit (300), and the operating unit (200) may be implemented to only perform control to light a specific button according to the linkage result.

[0058] You can select multiple message sending buttons at the same time, not just one.

[0059] For example, if two messages, “Stopped” and “Sorry,” are selected, the corresponding messages may be displayed alternately on the display unit (100) for a set period of time.

[0060] In addition, when a message is being transmitted on the display unit (100), if a different message transmission button is pressed, the existing message can be controlled to be terminated and the currently selected message can be output, and depending on the settings, the existing message and the currently selected message can be transmitted alternately at the same time.

[0061] The control unit (300) may include an AI learning unit (not shown). For example, the AI ​​learning unit may learn when a user actually presses a lit message sending button, and may operate the button so that it is automatically pressed even if the user does not actually press it, depending on the learning progress stage.

[0062] The AI ​​learning unit may be implemented in the control unit (300) itself, or in the user's smartphone that is linked to the control unit (300). Learning history may be stored in the user's smartphone and applied as is even when the user uses another vehicle.

[0063] In another embodiment, the message transmission buttons (B1, B2, ..) can be selected using the first button module (210) and the second button module (220). The second button module (220) has a simplified button shape.

[0064] The control unit (200) has the same configuration as the previous embodiment in that it lights up a message transmission button corresponding to the current driving state of the vehicle in conjunction with the driving state of the vehicle. That is, it lights up a message transmission button corresponding to the current driving state of the vehicle in conjunction with the driving state of the vehicle.

[0065] When a specific message transmission button of the first button module (210) lights up, the user “approves” transmission of a message corresponding to the message transmission button by operating the second button module (220) mounted on the steering wheel, rather than directly operating the first button module (210).

[0066] For example, when a vehicle comes to a sudden stop, a message transmission button corresponding to “sorry” in the first button module (210) lights up, and the user operates the “approval button” provided in the second button module (220) to cause the corresponding message to be displayed on the display unit (100).

[0067] That is, in this embodiment, it is easy to understand if the second button module (220) acts as a remote controller.

[0068] Although not shown, the second button module (220) can be implemented in a simplified form having three buttons.

[0069] The second button module (220) includes an “approval button” that performs approval of the message transmission button that is lit in the first button module (210), a “left selection button” that changes the selection of the message transmission button to the left, and a “right selection button” that changes the selection of the message transmission button to the right.

[0070] The user may select a message to be transmitted from the first button module (210) by operating the “right selection button” or the “left selection button” (i.e., selecting the message transmission button corresponding to the message) and then pressing the “approval button” to arbitrarily select and transmit a message.

[0071] Depending on the implementer, the second button module (220) may be implemented as an operation button built into the steering wheel of the vehicle through collaboration with the vehicle manufacturer.

[0072] Fig. 7 illustrates a first button module according to another embodiment. The first button module (210') according to this embodiment further includes a message display window (211) that actually displays the message content displayed on the display unit (100). The message display window (211) displays actual messages corresponding to the message transmission buttons (B1, B3). The illustrated example is an example of an actual message displayed when both "Yield" and "Thank You" are selected simultaneously.

[0073] Meanwhile, in order to be able to know when the number of characters in a message exceeds the number of characters displayed on the display unit (100), an area (100') corresponding to the resolution of the display unit (100) can be additionally displayed on the message display window (211). According to this configuration, the user can confirm in advance that the message is displayed in a loop manner in the area (100').

[0074] Figure 8 is a block diagram illustrating a safety message and advertisement transmission system using a vehicle display device according to the present invention. The safety message and advertisement transmission system (S) using a vehicle display device includes a vehicle display device (1000), a commercial server (C), and a mobile terminal (M).

[0075] Since the vehicle display device (1000) can be implemented using the vehicle display device (1000) described in FIGS. 2 to 7, redundant descriptions will be omitted. For concise implementation, a form in which the operating unit (200) is omitted can also be applied to the safety message and advertisement transmission system (S) of the present invention.

[0076] The commercial server (C) provides commercial information to the vehicle display device (1000). The commercial server (C) is located in a location such as a data center and encompasses both hardware for performing computational processing and software for processing information. Depending on the operator's choice, the commercial server (C) can be implemented on physically independent hardware or using a commercial cloud service.

[0077] Meanwhile, commercial information includes, for example, "advertisements," "local advertising," "traffic information," and "weather information." These examples are not limited to this, and information provided may be subject to change or addition depending on partnerships with information service providers.

[0078] The mobile terminal (M) is linked to the commercial server (C) so that commercial information is displayed on the vehicle display device (1000).

[0079] A mobile terminal (M) is a portable computer processing device with information and communication capabilities, such as a tablet PC or smartphone. A dedicated application (not shown) is installed and operated on the mobile terminal (M) to implement a safety message and advertisement transmission system. For ease of explanation and understanding, this dedicated application will be referred to as the "Message Display App."

[0080] The vehicle display device (1000) does not have a communication function that connects to the Internet and therefore cannot directly receive information from the commercial server (C). Therefore, it has a configuration that receives commercial information via a mobile terminal (M). However, if the vehicle display device (1000) is implemented with a remote communication function, the mobile terminal (M) can be omitted.

[0081] The commercial server (C) includes an information collection unit (C1), an advertisement provision unit (C2), and a revenue management unit (C3). The information collection unit (C1), advertisement provision unit (C2), and revenue management unit (C3) are logically separated to explain the operation of the commercial server (C). The actual program code that operates the commercial server (C) may differ.

[0082] The information collection unit (C1) receives driving information of the vehicle from the mobile terminal (M). Here, the "driving information" includes at least one of the route from the vehicle's departure point to its destination, the current vehicle location, and the current vehicle driving status (constant speed driving, stopping, acceleration, deceleration, lane change, etc.). The "driving information" can be collected by using a "message display app" operated on the mobile terminal (M) using devices such as a GPS module and an acceleration sensor module provided on the mobile terminal (M). The "route from the vehicle's departure point to its destination" can be collected by linking with a driving route guidance application (e.g., a commercial navigation app) operated on the mobile terminal (M).

[0083] The advertising provision unit (C2) determines commercial information to be displayed on the vehicle display device (1000) based on the information collected from the information collection unit (C1).

[0084] For example, if the location of the vehicle corresponds to a location where a "local advertisement" is requested in a specific area, the advertisement provider (C2) transmits a "local advertisement" message corresponding to the location to a "message display app" running on a mobile terminal (M), and the "message display app" controls the received "local advertisement" to be displayed on a vehicle display device (1000).

[0085] At this time, commercial information such as "local advertisements" are not displayed while the vehicle is in motion for safety reasons, and are set to be displayed only when the vehicle is stopped or moving slowly due to reasons such as waiting at a traffic light or traffic congestion.

[0086] The Revenue Management Department (C3) bills providers who provide commercial information based on whether or not the information is displayed, and accounts for revenue for users of vehicle display devices displaying the information. For example, a portion of advertising revenue may be provided to drivers of the corresponding vehicles based on the display location and number of times the message is displayed.

[0087] Although the present invention has been described with reference to the above embodiments, it will be understood by those skilled in the art that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
