[0042] In describing components according to embodiments of the disclosure, terms such as first, second, A, B, (a), (b), etc. can be used. These terms are merely intended to distinguish a component from other components, and the terms do not limit the nature, order or sequence of the component. Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0043] Figure 1 is a block diagram of an apparatus for controlling emotional lighting of a vehicle according to an embodiment of the disclosure.

[0044] As Figure 1 shown, the apparatus 100 for controlling emotional lighting of a vehicle according to an embodiment of the disclosure can include a memory 10, a setting apparatus 20, a camera 30, an emotional lighting apparatus 40, an actuator 50, and a controller 60. In this regard, based on a scheme for implementing the apparatus 100 for controlling emotional lighting of a vehicle according to an embodiment of the disclosure, these components can be combined with each other to be implemented as one component, or some components can be omitted.

[0045] Looking at each component, first, the memory 10 can store various logics, algorithms, and programs required in a process of photographing a surrounding area using the camera 30 included in the vehicle, detecting a representative color within a video of the surrounding area, and irradiating light of a color corresponding to the representative color to a vehicle door glass.

[0046] The memory 10 can store a table in which color information (RGB values) corresponding to each representative color is recorded. In this regard, when matching the color of the emotionalized lighting device 40 with each representative color, the effect of the emotionalized lighting device 40 can be maximized with reference to a color card as shown in FIG. 10. Figure 2 For example, when the representative color is blue, the color of the emotionalized lighting device 40 matched therewith can include at least one of sky blue, royal blue, azure, midnight blue, cyan, and / or sea blue. As another example, a first table can be generated based on a basic color card, a second table can be generated based on a color card giving a soft tone feeling, and a third table can be generated based on a color card giving a strong feeling.

[0047] The memory 10 can store a plurality of tables so that the user can select the color of the emotionalized lighting device 40 suitable for his / her taste. In this regard, different color information can be recorded for the representative color in the plurality of tables. For example, a first table can include at least one of sky blue and / or royal blue as the color of the emotionalized lighting device 40 matched with blue, which is the representative color. A second table can include at least one of azure and / or midnight blue as the color of the emotionalized lighting device 40 matched with blue, which is the representative color. A third table can include at least one of cyan and / or sea blue as the color of the emotionalized lighting device 40 matched with blue, which is the representative color.

[0048] The memory 10 can include at least one type of recording medium (storage medium) of a flash memory type, a hard disk type, a micro type, a card type (e.g., a secure digital card (SD card) or an eXtream digital card (XD card)), and the like, and a random access memory (RAM), a static RAM (SRAM), a read-only memory (ROM), a programmable ROM (PROM), an electrically erasable PROM (EEPROM), a magnetic RAM (MRAM), a magnetic disk, and an optical disk type memory.

[0049] The setting device 20 is a module that receives various settings from the user, and can include an input device of an audio video navigation (AVN) system 300 as an example.

[0050] The setting device 20 can receive a setting from the user regarding whether to operate (turn on / off) a mood mode. Such a mood mode can be activated as a default mode in a safe driving situation.

[0051] The setting device 20 can receive a setting regarding a mood mode or a music mode setting from a user. In this regard, the mood mode refers to a mode that makes the indoor atmosphere of the vehicle mild, or a mode that allows the emotional lighting device 40 to operate as indirect lighting of the indoor. The music mode is a mode that irradiates light that moves according to music output from the AVN system 300, which can make the driver alert and prevent the driver from driving while drowsy.

[0052] The camera 30 can photograph a video of an area around the vehicle. Such a camera 30 can include a front camera that photographs a video of a front area of the vehicle and a side camera that photographs a video of a side area of the vehicle. In this regard, the side camera can include a left side camera and a right side camera.

[0053] The emotional lighting device 40 is a lighting device capable of irradiating light of various colors under the control of the controller 60, which can be implemented as, for example, a red green blue (RGB) light emitting diode (LED) lighting.

[0054] Such an emotional lighting device 40 can be installed at an upper end of a door trim of the vehicle to irradiate light of various colors to a door glass or to irradiate light of various colors to the interior of the vehicle.

[0055] The actuator 50 is a module that rotates the emotional lighting device 40 and can adjust an irradiation direction of the emotional lighting device 40 under the control of the controller 60. Such an actuator 50 can include a step motor (not shown).

[0056] The controller 60 can perform overall control so that each component can normally perform its function. Such a controller 60 can be implemented in the form of hardware, can be implemented in the form of software, or can be implemented in the form of a combination of hardware and software with each other. The controller 60 can be implemented as a microprocessor, but can not be limited thereto.

[0057] In particular, the controller 60 can perform various controls in a process of photographing a video of an area around the vehicle using the camera 30 included in the vehicle, detecting a representative color within the video of the area around, and irradiating light of a color corresponding to the representative color to a door glass of the vehicle.

[0058] The controller 60 can acquire various vehicle information and driving information (e.g., vehicle speed, steering angle, etc.) through a vehicle network. In this regard, the vehicle network can include a controller area network (CAN), a controller area network with flexible data rate (CAN FD), a local interconnect network (LIN), FlexRay, a media oriented systems transport (MOST), Ethernet, etc.

[0059] The controller 60 can set a mood mode as a default mode.

[0060] Hereinafter, a description will be given with reference to Figures 3-4 The operation of the controller 60 will be described in detail.

[0061] Figure 3 is a schematic diagram illustrating a process of detecting a representative color in a front region video photographed by a camera by a controller included in the apparatus for controlling emotional lighting of a vehicle according to an embodiment of the disclosure.

[0062] As Figure 3 indicated, a front region video 310 photographed by the camera 30 in a state in which the vehicle travels can contain various colors. The controller 60 needs to set a region of interest (ROI) in the front region video 310 to detect a representative color from the front region video 310. In this regard, when a service is provided to a left-side passenger, the ROI can be, for example, a region '320', and when a service is provided to a right-side passenger, the ROI can be, for example, a region '330'. In Figure 3 , an example in which the front region video 310 is divided into 9 regions is described to help understanding, but the number of regions in which the front region video 310 is divided can be changed based on the designer's intention. Hereinafter, a case in which a service is provided to a left-side passenger will be described, but the same scheme can be applied to a case in which a service is provided to a right-side passenger.

[0063] As an example, the controller 60 can subdivide the ROI 320 into a first ROI (region 'A'), a second ROI (region 'B'), and a third ROI (region 'C'). This is a measure considering the vehicle speed. For example, the controller 60 can detect a representative color in the region 'A' when the vehicle speed is low (e.g., less than 50 kph), a representative color in a region in which the region 'A' and the region 'B' are combined when the vehicle speed is medium (e.g., greater than 50 kph and less than 80 kph), and a representative color in the region 320 in which the region 'A', the region 'B', and the region 'C' are combined when the vehicle speed is high (e.g., greater than 80 kph and less than 110 kph). In this regard, the representative color can be a color having the highest occupancy rate in the corresponding region.

[0064] As another example, the controller 60 can detect a representative color in the region 'A' when the vehicle speed is low (e.g., less than 50 kph), a representative color in the region 'B' when the vehicle speed is medium (e.g., greater than 50 kph and less than 80 kph), and a representative color in the region 'C' when the vehicle speed is high (e.g., greater than 80 kph and less than 110 kph).

[0065] Finally, the controller 60 can determine the ROI within the front region video 310 based on the vehicle speed. That is, the controller 60 can select the ROI from among the plurality of regions in the front region video 310 based on the vehicle speed. In the above, the embodiment considering the vehicle speed has been described, but the vehicle speed and the navigation route can be considered to determine the ROI in the front region video 310.

[0066] In one example, changing the color of the emotional lighting device 40 based on the representative color detected for each frame of the image results in too frequent changes, so that the controller 60 can determine the color having the highest occupancy for a predetermined number of frames as the representative color. In this regard, the number of frames can be determined based on the vehicle speed. For example, as the vehicle speed increases, the number of frames can decrease.

[0067] The controller 60 can determine the irradiation time point of the emotional lighting device 40 based on the vehicle speed. This is to match the time point at which the region in which the representative color is detected is reflected in the passenger's eyes through the door glass. That is, the controller 60 can control the emotional lighting device 40 to irradiate light of a color corresponding to the representative color at the time point at which the passenger views the region in which the representative color is detected through the door glass.

[0068] The controller 60 can control the emotional lighting device 40 to irradiate light of a color corresponding to the representative color detected in the above scheme to provide the driver or the passenger with an emotional landscape. The result thereof is shown as an example in Figure 4 .

[0069] Figure 4 is a schematic diagram showing a process of controlling emotional lighting by a controller included in the apparatus for controlling emotional lighting of a vehicle according to an embodiment of the disclosure.

[0070] As shown in Figure 4 , in a state in which the emotional mode is deactivated, the passenger views the original landscape through the door glass. However, in a state in which the emotional mode is activated, the passenger can view a landscape overlapping with the color of the emotional lighting device 40 through the door glass, thereby providing the passenger with emotional satisfaction.

[0071] In one example, the controller 60 can detect a representative color from a side region video taken by a side camera of the vehicle, and control the emotional lighting device 40 to irradiate light of a color corresponding to the detected representative color in a state in which the vehicle is stopped. In this regard, the controller 60 can detect the representative color from the entire region of the side region video.

[0072] Hereinafter, a scheme in which the controller 60 controls the actuator 50 will be described in detail with reference to Figures 5A-5D .

[0073] Figure 5A is a first schematic diagram illustrating an operating state of an actuator included in an apparatus for controlling emotional lighting of a vehicle according to an embodiment of the disclosure.

[0074] In Figure 5A , '510' denotes a door, '520' denotes a door glass, and '530' denotes a structure of an upper end of a door trim. The emotional lighting apparatus 40 can be installed at the upper end of the door trim. When a user sets a mood through the setting apparatus 20, or when the controller 60 operates in a default mode (mood mode), the controller 60 can control the actuator 50 so that light emitted from the emotional lighting apparatus 40 faces a door glass of the vehicle.

[0075] Figure 5B is a second schematic diagram illustrating an operating state of an actuator included in an apparatus for controlling emotional lighting of a vehicle according to an embodiment of the disclosure.

[0076] As Figure 5B indicated, when a warning signal is input from the warning system 200, the controller 60 can control the actuator 50 so that an emission direction of the emotional lighting apparatus 40 points to an upper end of the inside of the vehicle to warn the driver. In this regard, the controller 60 can control the emotional lighting apparatus 40 to emit light of a warning color (e.g., red or yellow).

[0077] In this regard, the warning system 200 can include at least one of an automatic emergency braking (AEB), a forward collision warning system (FCW), an adaptive cruise control (ACC), a lane departure warning system (LDWS), a lane keeping assist system (LKAS), a blind spot detection (BSD), a rear collision warning system (RCW), an intelligent parking assist system (SPAS), and / or an advanced driver assistance system (ADAS).

[0078] Figure 5C is a third schematic diagram illustrating an operating state of an actuator included in an apparatus for controlling emotional lighting of a vehicle according to an embodiment of the disclosure.

[0079] As Figure 5C indicated, when a user sets a mood through the setting apparatus 20, the controller 60 can control the actuator 50 so that an emission direction of the emotional lighting apparatus 40 points to a lower end of the inside of the vehicle. In this regard, the controller 60 can control the emotional lighting apparatus 40 to emit light of a color that gives a soft feeling (e.g., light blue, light orange, etc.). In addition, the controller 60 can further control the emotional lighting apparatus 40 to emit light of a color having high visibility (e.g., a color adjacent to external light on a color chart) in a case where external light is strong (e.g., during the day).

[0080] In one example, the controller 60 can control the mood mode in conjunction with the emotion mode. That is, the controller 60 can control the emotional lighting device 40 to irradiate light corresponding to a representative color in the emotion mode to a lower end of the interior of the vehicle.

[0081] Figure 5D is a fourth diagram illustrating an operation state of an actuator included in a device for controlling emotional lighting of a vehicle according to an embodiment of the present disclosure.

[0082] As Figure 5D indicated, when the user sets the music mode through the setting device 20, the controller 60 can control the actuator 50 so that the light of the emotional lighting device 40 reciprocates a predetermined portion according to the music output through the AVN system 300. In this regard, the controller 60 can control the emotional lighting device 40 to flash in a plurality of vivid colors (e.g., red, green, and blue).

[0083] Figure 6 is a flowchart of a method for controlling emotional lighting of a vehicle according to an embodiment of the present disclosure.

[0084] First, the camera 30 photographs a front region video of the vehicle (601).

[0085] Thereafter, the controller 60 detects a representative color within the front region video (602).

[0086] Thereafter, the controller 60 controls the emotional lighting device 40 to irradiate light of a color corresponding to the representative color (603).

[0087] Thereafter, the emotional lighting device 40 irradiates the light toward a door glass of the vehicle (604).

[0088] Figure 7 is a flowchart of a method for controlling emotional lighting of a vehicle according to another embodiment of the present disclosure.

[0089] First, the camera 30 photographs a side region video of the vehicle (701).

[0090] Thereafter, the controller 60 detects a representative color within the side region video (702).

[0091] Thereafter, the controller 60 controls the emotional lighting device 40 to irradiate light of a color corresponding to the representative color (703).

[0092] Thereafter, the emotional lighting device 40 irradiates the light toward a door glass of the vehicle (704).

[0093] Figure 8 is a block diagram of a computing system for performing a method of controlling emotional lighting of a vehicle according to an embodiment of the present disclosure.
