DISCUSSION OF THE BACKGROUND



[0002] In general, an image display apparatus refers to an apparatus that outputs information as an image using a screen. The image display apparatus may include a general monitor as one of computer output apparatuses. Output data are mostly expressed as characters, symbols, figures, images, voice and the like. All data except the voice, among the above-described data, are recognized with the eyes. The image display apparatus temporarily displays such information through the screen.

[0003] Examples of such an image display apparatus include a CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), TFT-LCD (Thin Film Transistor-LCD), PDP (Plasma Display), flexible display, HMD (Head Mounted Display) and the like.

[0004] Recently, a flip-dot display has been developed, which rotates a flip disk having surfaces with different colors by changing the polarity of an electromagnet, thereby implementing a pixel.

[0005] The related art of the present disclosure is disclosed in Korean Patent No. 10-1487904 published on February 4, 2015 and entitled "Flip Dot Display Element using Electromagnet and Assembly Module Thereof".

[0006] An autopilot system is embedded in various driving units for a driver, and performs autonomous driving through driving location search. The autopilot system is mainly applied to a ship, airplane and the like. Recently, the autopilot system is also applied to a vehicle that travels on the road, and informs a user of various pieces of information such as a traveling route and road congestion through a monitor, or autonomously drives the vehicle or controls the traveling state of the vehicle.

[0007] An autonomous vehicle having such an autopilot system mounted therein needs to not only warn a pedestrian of the vehicle's approaching such that the pedestrian can pay attention to the vehicle, but also transfer the driving state of the vehicle to an oncoming vehicle such that the oncoming vehicle recognizes the autonomous driving state.

[0011] When outputting any one of the recognition information, the warning information and the cancellation information through the flip-dot display, the control unit may output any one or more of a symbol, icon, image and character as the information.

[0012] The vehicle information display apparatus may further include the operation sound output unit configured to notify the operation state of the information display apparatus. When outputting the warning information, the control unit may operate the flip-dot display to output a warning sign, and increase the volume of the operation sound output unit to output a warning sound.

[0013] The control unit may output the recognition information when the detected distance at which the forward object is detected falls within a preset distance, output the warning information when the detected distance falls within a warning distance, and output the cancellation information when the detected distance increases or the object detection is canceled.

[0014] The control unit may receive the vehicle state, and outputs a driving state through the flip-dot display according to a driving mode. The control unit may differently display and output an autonomous driving state, a semi-autonomous driving state and a driver onboard state according to the driving mode.

[0015] The vehicle information display apparatus may further include an illuminance sensor configured to detect ambient brightness of the vehicle. When operating the flip-dot display according to the ambient brightness, the control unit may operate the illumination module.

[0016] The flip disk of the flip-dot display may have a front surface and a rear surface which have different reflection characteristics.

[0017] The illumination module may include a daytime driving light module, and the daytime driving light module may be disposed along the edge of the flip-dot display.

[0018] The flip-dot display may be installed at one or more of a front grill, trunk, roof, rear bumper and rear window glass of the vehicle.

[0019] The flip-dot display may be formed at a front grill of the vehicle such that the central portion thereof has a protruding curved surface.

[0020] In an embodiment, a control method of a vehicle information display apparatus may include: receiving, by a control unit, a vehicle state and a detection result of a forward object; receiving, by the control unit, the vehicle state and the detection result of the forward object, and determining whether the forward object is detected while the vehicle travels; and outputting any one of recognition information, warning information and cancellation information by operating a flip-dot display according to a detected distance of the forward object, when the forward object is detected during driving.

[0021] The flip-dot display may include a flip disk having a front surface and a rear surface which have different reflection characteristics.

[0022] In the outputting of any one of the recognition information, the warning information and the cancellation information, the control unit may output any one or more of a symbol, icon, image and character as the information through the flip-dot display.

[0023] When outputting the warning information, the control unit may operate the flip-dot display to output a warning sign, and increase the volume of an operation sound output unit to output a warning sound.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS



[0030] As is traditional in the corresponding field, some exemplary embodiments may be illustrated in the drawings in terms of functional blocks, units, and/or modules. Those of ordinary skill in the art will appreciate that these block, units, and/or modules are physically implemented by electronic (or optical) circuits such as logic circuits, discrete components, processors, hard-wired circuits, memory elements, wiring connections, and the like. When the blocks, units, and/or modules are implemented by processors or similar hardware, they may be programmed and controlled using software (e.g., code) to perform various functions discussed herein. Alternatively, each block, unit, and/or module may be implemented by dedicated hardware or as a combination of dedicated hardware to perform some functions and a processor (e.g., one or more programmed processors and associated circuitry) to perform other functions.

Further, blocks, units, and/or module of some exemplary embodiments may be physically combined into more complex blocks, units, and/or modules without departing from the scope of the inventive concept.

[0031] Hereinafter, a vehicle information display apparatus and a control method thereof will be described below with reference to the accompanying drawings through various exemplary embodiments. It should be noted that the drawings are not to precise scale and may be exaggerated in thickness of lines or sizes of components for descriptive convenience and clarity only. Furthermore, the terms as used herein are defined by taking functions of the invention into account and can be changed according to the custom or intention of users or operators. Therefore, definition of the terms should be made according to the overall disclosures set forth herein.

[0032] FIG. 1 is a block configuration diagram illustrating a vehicle information display apparatus in accordance with an embodiment of the present disclosure, FIG. 2 is a diagram illustrating that the vehicle information display apparatus in accordance with the embodiment of the present disclosure is mounted, FIG. 3 is a configuration diagram illustrating a flip-dot display of the vehicle information display apparatus in accordance with the embodiment of the present disclosure, FIG. 4 is a diagram illustrating that cancellation information is displayed through the vehicle information display apparatus in accordance with the embodiment of the present disclosure, and FIG. 5 is a diagram illustrating pixel images which can be displayed through the vehicle information display apparatus in accordance with the embodiment of the present disclosure.

[0033] As illustrated in FIG. 1, the vehicle information display apparatus in accordance with the embodiment of the present disclosure may include a vehicle state input unit 10, a front detection unit 20, an illuminance sensor 30, an operation sound output unit 50, a flip-dot display 60, an illumination module 70 and a control unit 40.

[0034] The vehicle state input unit 10 may receive the operation state and driving state of a vehicle, and provide the received information to the control unit 40. Thus, the control unit 40 can determine a situation which is to be transferred to a pedestrian or oncoming vehicle, and control the flip-dot display 60 to display the situation.

[0035] For example, the control unit 40 may determine whether the vehicle is traveling, and determine an autonomous driving state, a semi-autonomous driving state, a driver onboard state, a stop state, a state in which the vehicle is started after being stopped, an acceleration state or the like.

[0036] The front detection unit 20 may detect a forward object ahead of the vehicle, and provide the detected information to the control unit 40, such that the control unit 40 can output any one of recognition information, warning information and cancellation information according to the detected distance at which the forward object is detected.

[0037] The illuminance sensor 30 may sense the ambient brightness of the vehicle and provide the sensed information to the control unit 40. Thus, the illumination module 70 may be automatically operated even though the illumination module is not independently operated according to the ambient brightness.

[0038] The operation sound output unit 50 may notify the operation state of the vehicle information display apparatus, such that a pedestrian recognizes the state in which the vehicle is approaching.

[0039] The operation sound output unit 50 may amplify and output the sound of a VESS (Virtual Engine Sound System).

[0040] The flip-dot display 60 may be installed at a front grill of the vehicle as illustrated in FIG. 2, and have a central portion with a protruding curved surface, such that light of the illumination module 70 disposed around the flip-dot display 60 is emitted to secure visibility even in the nighttime.

[0041] In the present embodiment, the case in which the flip-dot display 60 is installed at the front grill is taken as an example for description. However, the flip-dot display 60 may be mounted not only at a trunk, roof, rear bumper or rear window glass of the vehicle, but also inside the vehicle, in order to display information of the vehicle.

[0042] As illustrated in FIG. 3, the flip-dot display 60 may implement a pixel by rotating a flip disk 62 whose front and rear surfaces have different colors. With this structure that rotates the flip disk 62 by changing the polarity of an electromagnet, the volume and weight of the vehicle information display apparatus may be reduced further than a structure that rotates the flip disk by using an actuator, which makes it possible to reduce the manufacturing cost.

[0043] The flip-dot display 60 may implement a pixel by rotating the flip disk 62 whose front and rear surfaces have different colors, and thus improve visibility in the daytime, compared to a light emitting display.

[0044] When the flip-dot display 60 is installed outside the vehicle, the flip-dot display 60 may further include a cover for preventing foreign matters.

[0045] As illustrated in FIG. 2, the illumination module 70 may be installed around the flip-dot display 60, and illuminate the surface of the flip-dot display 60 to improve the visibility in the nighttime.

[0046] At this time, when the front and rear surfaces of the flip disk 62 are configured to have different reflection characteristics (e.g. gloss and matt), the reflectance of the light may be changed by the rotation angle of the flip disk 62 whose front and rear surfaces have different reflection characteristics, depending on the installation angle of the illumination module 70. Thus, various pieces of information may also be displayed through light reflected from a road surface, which makes it possible to improve the visibility in the nighttime.

[0047] The illumination module 70 may include any one or more of a headlight module 71, a turn indicator module 72, a position lamp module 73, a daytime driving light module 74 and the like.

[0048] Furthermore, the daytime driving light module 74 may be disposed along the edge of the flip-dot display 60, and operated by a daytime driving light turn-on switch (not illustrated) in the daytime or operated according to the ambient brightness in the nighttime, thereby illuminating the flip-dot display 60 to improve the visibility in the nighttime.

[0049] The control unit 40 may receive the vehicle state from the vehicle state input unit 10, and output information based on the vehicle state through the flip-dot display 60.

[0050] For example, as illustrated in FIG. 5, the flip-dot display 60 may not only display various pieces of information using pixel icons or the like, but also display information through symbols, icons, images and characters. Depending on a driving mode, the flip-dot display 60 may differently display the autonomous driving state, the semi-autonomous driving state, and the driver onboard state.

[0051] Furthermore, the control unit 40 may operate any one or more of the flip-dot display 60 and the operation sound output unit 50 according to the vehicle state and the detected distance at which the forward object is detected by the front detection unit 20, and thus output any one of the recognition information, the warning information and the cancellation information.

[0052] The control unit 40 may output the recognition information when the detected distance at which the forward object is detected falls within a preset distance, output the warning information when the detected distance falls within a warning distance, and output the cancellation information when the detected distance increases or the object detection is canceled.

[0053] For example, when outputting the warning information, the control unit 40 may not only operate the flip-dot display 60 to output a warning sign, but also raise the volume of the operation sound output unit 50 to output a warning sound, such that a pedestrian can directly recognize the vehicle's approaching.

[0054] The cancellation information may be displayed as an emotional icon indicating a thank-you sign as illustrated in FIG. 4.

[0055] When outputting any one of the recognition information, the warning information and the cancellation information through the flip-dot display 60, the control unit 40 may output any one or more of a symbol, icon, image and character as the information. At this time, the control unit 40 may differently display and output the driving state of the vehicle, according to the autonomous driving state, the semi-autonomous driving state, the driver onboard state or the like.

[0056] When operating the flip-dot display 60 according to the ambient brightness inputted from the illuminance sensor 30, the control unit 40 may operate the illumination module 70 to improve the visibility in the nighttime.

[0057] When the vehicle state from the vehicle state input unit 10 corresponds to a welcome mode, the control unit 40 may output music through the operation sound output unit 50, and output an animation or welcome signal suitable for the rhythm of the output music through the flip-dot display 60, in order to output welcome information.

[0058] As described above, the vehicle information display apparatus in accordance with the present embodiment may include the flip-dot display installed in the vehicle and the illumination device installed around the flip-dot display, and output the driving state of the vehicle as various motions and operation sounds through the flip-dot display according to the vehicle state and the detection state of the forward object. Thus, the vehicle information display apparatus may accurately transfer information to a pedestrian or oncoming vehicle in the daytime or nighttime, thereby improving the visibility and transfer force. Furthermore, the vehicle information display apparatus may drive the flip disk using an electromagnet. Therefore, it is possible to reduce the volume and weight of the vehicle information display apparatus and to reduce the manufacturing cost thereof, thereby increasing the productivity thereof.

[0059] FIG. 6 is a flowchart for describing a control method of a vehicle information display apparatus in accordance with an embodiment of the present disclosure.

[0060] As illustrated in FIG. 6, the control method of the vehicle information display apparatus in accordance with the embodiment of the present disclosure starts with step S10 in which the control unit 40 receives a vehicle state from the vehicle state input unit 10, and receives a detection result of a forward object from the front detection unit 20.

[0061] After receiving the vehicle state in step S10, the control unit 40 determines whether the vehicle state corresponds to a welcome mode, in step S20.

[0062] When the determination result of step S20 indicates that the vehicle state corresponds to the welcome mode, the control unit 40 may output music through the operation sound output unit 50, and output an animation or welcome signal suitable for the rhythm of the output music through the flip-dot display 60, in order to output welcome information, in step S30.

[0063] When the determination result of step S20 indicates that the vehicle state does not correspond to the welcome mode, the control unit 40 determines whether the vehicle is traveling, in step S40.

[0064] When the determination result of step S40 indicates that the vehicle is not traveling, the control unit 40 may return to step S10 to receive the vehicle state and the detection result of the forward object.

[0065] On the other hand, when the determination result of step S40 indicates that the vehicle is traveling, the control unit 40 determines whether the detected distance at which the forward object is detected falls within a preset distance, in step S50.

[0066] When the determination result of step S50 indicates that no forward object is detected or the detected distance does not fall within the preset distance, the control unit 40 may return to step S10 to continuously receive the vehicle state and the detection result of the forward object.

[0067] However, when the determination result of step S50 indicates that the detected distance falls within the preset distance, the control unit 40 operates the flip-dot display 60 and the operation sound output unit 50 to output recognition information, in step S60.

[0068] As illustrated in FIG. 2, the flip-dot display 60 may be installed at the front grill of the vehicle so as to transfer the vehicle state to a pedestrian or oncoming vehicle. However, the flip-dot display 60 may be mounted not only at the trunk, roof, rear bumper or rear window glass of the vehicle, but also inside the vehicle, in order to display information of the vehicle.

[0069] As illustrated in FIG. 3, the flip-dot display 60 may display information by implementing a pixel through a process of rotating the flip disk 62 whose front and rear surface have different colors, by changing the polarity of the electromagnet, thereby improving the visibility in the daytime. At this time, the operation sound output unit 50 may output a virtual engine sound as an operation sound of the flip-dot display 60.

[0070] As illustrated in FIG. 2, the illumination module 70 may be installed around the flip-dot display 60 so as to illuminate the surface of the flip-dot display 60, thereby improving the visibility in the nighttime.

[0071] At this time, when the front and rear surfaces of the flip disk 62 are configured to have different reflection characteristics (e.g. gloss and matt), the reflectance of the light may be changed by the rotation angle of the flip disk 62 whose front and rear surfaces have different reflection characteristics, depending on the installation angle of the illumination module 70. Thus, various pieces of information may also be displayed through light reflected from a road surface, which makes it possible to improve the visibility in the nighttime.

[0072] After outputting the recognition information in step S60, the control unit 40 determines whether the detected distance falls within the warning distance, in step S70.

[0073] When the determination result of step S70 indicates that the detected distance falls within the warning distance, the control unit 40 operates the flip-dot display 60 and the operation sound output unit 50 to output warning information, in step S80.

[0074] At this time, in order to warn a pedestrian of the vehicle's approaching, the control unit 40 may increase the volume of the operation sound output unit 50, and output a warning sound.

[0075] When the determination result of step S70 indicates that the detected distance does not fall within the warning distance or after outputting the warning information in step S80, the control unit 40 determines whether the object detection has been canceled, in step S90.

[0076] When the determination result of step S90 indicates that the detected distance increases or the object detection is not canceled because no object is detected, the control unit 40 may return to step S70 to continuously determine whether the detected distance falls within the warning distance.

[0077] However, when the determination result of step S90 indicates that the object detection has been canceled, the control unit 40 operates the flip-dot display 60 and the operation sound output unit 50 to output cancelation information, in step S100.

[0078] For example, as illustrated in FIG. 4, the control unit 40 may output an emotional icon indicating a thank-you sign as the cancellation information.

[0079] When outputting any one of the recognition information, the warning information and the cancellation information through the flip-dot display 60, the control unit 40 may output a symbol, icon, image or character as the information, as illustrated in FIG. 5. At this time, according to the driving mode, the control unit 40 may differently display and output the driving state of the vehicle such as the autonomous driving state, the semi-autonomous driving state or the driver onboard state.

[0080] When outputting the recognition information, the warning information and the cancellation information according to the detected distance of the forward object, the control unit 40 may determine the ambient brightness inputted from the illuminance sensor 30, and operate the daytime driving light module 74 of the illumination module 70, disposed along the edge of the flip-dot display 60, so as to illuminate the flip-dot display 60, thereby improving the visibility in the nighttime.

[0081] In the above-described control method of the vehicle information display apparatus in accordance with the present embodiment, the flip-dot display may be installed in the vehicle, the illumination device may be installed around the flip-dot display, and various motions and operation sounds may be outputted as the driving state of the vehicle through the flip-dot display according to the vehicle state and the detection state of the forward object. Thus, information can be accurately transferred to a pedestrian or oncoming vehicle in the daytime or nighttime, which makes it possible to improve the visibility and transfer force.

[0082] The embodiments described in this specification may be implemented with a method or process, a device, a software program, a data stream or a signal, for example. Although a feature is discussed only in a single context (for example, discussed only in a method), the discussed feature can be implemented in another type (for example, apparatus or program). An apparatus may be implemented in suitable hardware, software or firmware. The method can be implemented in a device such as a processor which generally refers to a processing device including a computer, a microprocessor, an integrated circuit or a programmable logic device. The processor also includes a communication device, such as a computer, cellular phone, PDA (Personal Digital Assistant) and another device, which facilitates information communication between end users.
