Description

Technical Field

[0001] This disclosure relates to screen control devices, methods, and systems for moving objects. Background Technology

[0002] Typically, vehicles can use their illuminance sensors to measure illuminance and adjust the screens and brightness of devices in the vehicle based on the measured illuminance.

[0003] Here, in order to adjust the screen and screen brightness, an illuminance sensor should be installed in the vehicle or equipment.

[0004] Recently, it has become possible to receive and share illuminance information from another device via a communication interface without the need to install illuminance sensors directly in the vehicle. However, determining whether the shared illuminance information is suitable for the in-vehicle device's screen is not easy. Summary of the Invention

[0015] The screen control device may also include a weight learning device, which learns weights determined by user settings.

[0016] The weight of each reference item can be determined based on the results of the learning weights.

[0017] The illuminance determination device can select the illuminance measurement data with the highest illuminance fraction as the reference illuminance measurement data.

[0018] When the chromaticity of the reference illuminance measurement data differs from the chromaticity of the moving object, the illuminance determination device can correct the illuminance based on the chromaticity of the reference illuminance measurement data and the chromaticity of the moving object.

[0035] Figure 1 This is a block diagram illustrating a system according to an embodiment of the present disclosure.

[0036] refer to Figure 1 The system may include one or more mobile objects 11 to 19 that provide information, a server 20, and a mobile object 30. Here, the system may be a connected car system.

[0037] The mobile objects 11 to 19 and mobile object 30 that provide information may correspond to mobile devices, each of which has a display. As an example, the mobile objects 11 to 19 and mobile object 30 that provide information may include various types of mobile devices, such as vehicles, electric kickboards, and urban air mobility (UAM) devices. Here, in the following embodiments, for ease of description, mobile object 30 is described as a vehicle, but is not limited thereto.

[0038] One or more information-providing moving objects 11 to 19 may include moving objects with illuminance sensors. In this case, the information-providing moving object 10 may adjust the screen brightness in the moving object 30 according to the illuminance value measured by the illuminance sensor.

[0039] The information-providing mobile object 10 can communicatively connect to the server 20 to transmit illuminance measurement data to the server 20 in real time during illuminance measurement. Whenever an illuminance change event occurs, the information-providing mobile object 10 can transmit the illuminance measurement data to the server 20.

[0040] Here, illuminance measurement data may include information such as measurement time, measurement location, driving direction, sensor information, weather information, moving object information (e.g., model, vehicle type, etc.) and / or chromaticity, as well as illuminance information measured by the illuminance sensor.

[0041] Server 20 may be a connected car service (CCS) server. Server 20 may be communicatively connected to one or more information-providing mobile objects 11 to 19 and / or mobile object 30 to provide CCS to one or more information-providing mobile objects 11 to 19 and / or mobile object 30.

[0042] Server 20 can collect and manage illuminance measurement data from one or more mobile objects 11 to 19 that provide information. In this case, server 20 can provide the collected illuminance measurement data to mobile objects 30 that do not have illuminance sensors.

[0043] Here, server 20 can extract illuminance measurement data within a certain range from the current position of moving object 30, and can provide illuminance measurement data to moving object 30 based on the current position of moving object 30.

[0044] Server 20 can provide the moving object 30 with real-time collected illuminance measurement data. Server 20 can also provide the moving object 30 with illuminance measurement data collected during a specific time period in each specific time period.

[0045] Since the moving object 30 does not have an illuminance sensor, it can communicate with the server 20 to receive illuminance measurement data from the server 20.

[0046] Here, the moving object 30 may include a screen control device 100. The screen control device 100 may use illuminance measurement data received from the server 20 to adjust the screen brightness of the display. In this case, the screen control device 100 may calculate an illuminance score for each received data point and may determine a suitable screen brightness for the display based on the calculated illuminance score.

[0047] The screen control device 100 for a moving object according to an embodiment of the present disclosure can be implemented in the moving object 30. In this case, the screen control device 100 can be integrated with the control unit in the moving object 30 or can be implemented as a separate device connected to the control unit of the moving object 30 via a separate connection device. Therefore, referring to Figure 2The embodiments describe the detailed configuration and operation of the screen control device 100.

[0048] Figure 2 This is a block diagram illustrating the configuration of a screen control device for a moving object according to an embodiment of the present disclosure.

[0049] refer to Figure 2 The screen control device 100 for moving objects may include a controller 110, an interface 120, a communication device 130, a storage device 140, an illuminance score calculation device 150, a weight learning device 160, and an illuminance determination device 170. Here, the controller 110, illuminance score calculation device 150, weight learning device 160, and illuminance determination device 170 of the screen control device 100 may be implemented as at least one processor.

[0050] The controller 110 can control the operation of each component of the screen control device 100 and can process the signals transmitted between the components.

[0051] Interface 120 may include an input device for receiving control commands from a user and an output device for outputting the operating status, operating results, etc. of the screen control device 100.

[0052] Here, the input device may include key buttons and soft keys implemented on the display. Additionally, the input device may include a mouse, joystick, jog shuttle, stylus, etc.

[0053] The output device may include a display and may include a voice output device such as a speaker.

[0054] In this case, when a touch sensor such as a touch film, touch sheet, or touchpad is provided in the display, the display can operate as a touch screen and can be implemented in a form in which the input and output devices are integrated with each other.

[0055] In this case, the display may include at least one of a liquid crystal display (LCD), a thin film transistor-LCD (TFT-LCD), an organic light-emitting diode (OLED) display, a flexible display, a field emission display (FED), or a three-dimensional (3D) display.

[0056] The communication device 130 may include a communication module for communicating with electronic devices and / or controllers disposed in the moving object 30 via a vehicle network.

[0057] Here, technologies used for vehicle network communication may include Controller Area Network (CAN) communication, Local Interconnect Network (LIN) communication, flexible ray communication, etc.

[0058] In addition, the communication device 130 may include a communication module for accessing the wireless Internet or a communication module for short-range communication.

[0059] Here, technologies used for wireless internet may include wireless local area networks (WLAN), wireless broadband (WiBro), wireless fidelity (Wi-Fi), and microwave access global interoperability (WiMAX), etc.

[0060] In addition, technologies used for short-range communication may include Bluetooth, ZigBee, ultra-wideband (UWB), radio frequency identification (RFID), Infrared Data Association (IrDA), etc.

[0061] As an example, the communication module can be used with Figure 1 The communication module establishes a communication connection with server 20 to receive illuminance measurement data from server 20. In this case, the communication module can receive illuminance measurement data in real time or at a certain time interval.

[0062] The storage device 140 can store data, algorithms, etc. required for the operation of the screen control device 100.

[0063] As an example, storage device 140 may store illuminance measurement data received from server 20. Furthermore, storage device 140 may store commands and / or algorithms for calculating illuminance scores from the illuminance measurement data to determine illuminance and adjusting the screen brightness of the display based on the illuminance. Additionally, storage device 140 may store weighting information applied when calculating the illuminance score and algorithms for learning the weights.

[0064] Here, storage device 140 may include storage media such as random access memory (RAM), static RAM (SRAM), read-only memory (ROM), programmable ROM (PROM), or electrically erasable PROM (EEPROM).

[0065] When the controller 110 receives illuminance measurement data from the server 20 via the communication device 130, it can transmit the received illuminance measurement data to the illuminance fraction calculation device 150.

[0066] refer to Figure 3 An example describing illuminance measurement data. Figure 3 This is a diagram illustrating an embodiment of illuminance measurement data according to an embodiment of the present disclosure.

[0067] refer to Figure 3 Illuminance measurement data may include information such as measurement time, measurement location, driving direction, sensor information, weather information, moving object information (e.g., model, vehicle type, etc.) and / or chromaticity, as well as illuminance information measured by the illuminance sensor.

[0068] In this case, from Figure 1The illuminance measurement data received by server 20 can be based on the current position of the moving object 30 at a distance from... Figure 1 The illuminance is measured within a specific range of the current position of the moving object 30. One or more illuminance measurement data can be received from the server 20.

[0069] Figure 2 The illuminance fraction calculation device 150 can calculate the illuminance fraction of illuminance measurement data. In this case, the illuminance fraction calculation device 150 can calculate the illuminance fraction of one or more illuminance measurement data received from the server 20.

[0070] At this time, the illuminance fraction calculation device 150 can calculate the illuminance fraction of all illuminance measurement data received from the server 20. Simultaneously, the illuminance fraction calculation device 150 can select a certain number of received illuminance measurement data in the following order: from the most received to the least received among multiple received illuminance measurement data, and can calculate the illuminance fraction of the selected illuminance measurement data.

[0071] Depending on the implementation method, the standard for selecting illuminance measurement data can be applied in various ways.

[0072] The illuminance score calculation device 150 can calculate the illuminance score for each data point based on information included in the illuminance measurement data, such as measurement time, measurement location, driving direction, sensor information, weather information, moving object information (e.g., model, vehicle type, etc.) and / or chromaticity.

[0073] As an example, the illuminance score calculation device 150 can calculate the illuminance score for each data point based on all items included in the illuminance measurement data.

[0074] Meanwhile, the illuminance score calculation device 150 can calculate the illuminance score for each data point based on certain items among multiple pieces of information included in the illuminance measurement data. Here, the reference items used for calculating the illuminance score can be determined in various ways depending on the implementation. For example, the reference items can be pre-selected by the user. Alternatively, reference items can be automatically selected through a learning algorithm.

[0075] At this time, the illuminance score calculation device 150 can compare the information of the moving object 30 with multiple pieces of information included in the illuminance measurement data, and can calculate the illuminance score based on items that are the same as each other.

[0076] refer to Figure 4 An example of the operation for calculating the illuminance score for each data point. Figure 4 This is a diagram illustrating an embodiment to which the operation of calculating illuminance fractions is described according to embodiments of the present disclosure.

[0077] refer to Figure 4 , Figure 2The illuminance fraction calculation device 150 can calculate the illuminance fraction of three illuminance measurement data, namely data A, data B and data C.

[0078] In this case, the illuminance score calculation device 150 can calculate the illuminance score based on some of the items included in each data, such as measurement time, driving direction, weather information, model, sensor, and chromaticity.

[0079] The standard used to calculate the illuminance fraction is the time difference between the current time and the illuminance measurement time. When relative to... Figure 1 Assuming the current time is “0”, the illuminance fraction calculation device 150 can assign a fraction to data A for use in standard A, since the time difference between the current time and the time of measurement data A is 10 minutes, the time difference between the current time and the time of measurement data B is 24 hours and 5 minutes, and the time difference between the current time and the time of measurement data C is 12 hours.

[0080] The standard 2 used to calculate the illuminance fraction is the direction of travel. Since the direction of travel of the target moving object 30 is downward, the direction of travel of data A is upward, and the direction of travel of data B and C is downward, the illuminance fraction calculation device 150 can assign a fraction to each of data B and C for use in standard 2.

[0081] The standard 3 used to calculate the illuminance score is weather information. Since the weather around the moving object 30 is rainy, the weather around data A is cloudy, the weather around data B is rainy, and the weather around data C is sunny, the illuminance score calculation device 150 can assign a score to data B for use in standard 3.

[0082] The standard 4 used to calculate the illuminance score is the vehicle type. Since the vehicle type of the target moving object 30 is a sedan, the vehicle types of data A and B are SUVs, and the vehicle type of data C is a sedan, the illuminance score calculation device 150 can assign a score to data C for use in standard 4.

[0083] The standard 5 used to calculate the illuminance fraction is a sensor. Since the current sensor of the moving object 30 is manufactured by Company A, the sensor of data A is manufactured by Company A, and the sensors of data B and C are manufactured by Company B, the illuminance fraction calculation device 150 can assign a fraction to data A for use in the standard 5.

[0084] Finally, the standard 6 used to calculate the illuminance score is chromaticity. Since the chromaticity of the currently moving object 30 is 30, the chromaticity of data A is 30, the chromaticity of data B is 50, and the chromaticity of data C is 20, the illuminance score calculation device 150 can assign a score to data A for use in standard 6.

[0085] In this case, the illuminance score calculation device 150 can assign one point to each reference item and add the score assigned to each reference item to calculate the illuminance score for each data point.

[0086] For standards 1, 5, and 6, data A is assigned one point each time, resulting in a final illuminance score of 3 points. For standards 2 and 3, data B is assigned one point each time, resulting in a final illuminance score of 2 points. For standards 2 and 4, data C is assigned one point each time, resulting in a final illuminance score of 2 points.

[0087] The illuminance fraction calculation device 150 can transmit the illuminance fraction calculated for each data point to... Figure 2 Illuminance determination equipment 170.

[0088] Therefore, the illuminance determining device 170 can select the data with the highest illuminance score as the reference illuminance measurement data and determine the illuminance based on the reference illuminance measurement data. Figure 4 In one embodiment, because data A has the highest illuminance score, the illuminance determination device 170 can determine data A as reference illuminance measurement data and can determine the illuminance data A to be applied to the moving object 30 based on the illuminance information.

[0089] In this scenario, the illuminance determination device 170 can compare the chromaticity of the moving object 30 with the chromaticity of reference illuminance measurement data. When the chromaticities differ from each other, the illuminance determination device 170 can adjust the illuminance based on the chromaticity of the moving object 30.

[0090] Here, since the chromaticity of data A, which serves as the reference illuminance measurement data, is the same as that of the moving object 30, the illuminance determination device 170 can determine the illuminance of data A as the illuminance to be applied to the moving object 30 without illuminance adjustment.

[0091] When the illuminance determining device 170 determines the illuminance. Figure 2 The controller 110 can adjust the screen brightness of the display based on a determined illuminance.

[0092] Meanwhile, when calculating the illuminance score for each data point, the illuminance score calculation device 150 can apply weights to each reference item to calculate the illuminance score.

[0093] Here, the weights used for each reference item can be assigned to environmental variables based on environmental sensor values.

[0094] refer to Figure 5 This describes an embodiment of the operation that reflects the calculation of illuminance scores based on weights assigned to environmental variables. Figure 5 This is a diagram illustrating an embodiment of the operation for calculating illuminance fractions, according to another embodiment of the present disclosure.

[0095] refer to Figure 5 , Figure 2 The illuminance fraction calculation device 150 can calculate the illuminance fraction of three illuminance measurement data, namely data A, data B and data C.

[0096] In this case, the illuminance score calculation device 150 can calculate the illuminance score based on some items included in each data point, such as measurement time, driving direction, weather information, vehicle type, sensor, and chromaticity.

[0097] Each reference item used to calculate illuminance score and Figure 4 The embodiments are the same.

[0098] Therefore, for standards 1, 5, and 6, data A is assigned one point each time, resulting in a final illuminance score of 3 points. For standards 2 and 3, data B is assigned one point each time, resulting in a final illuminance score of 2 points. For standards 2 and 4, data C is assigned one point each time, resulting in a final illuminance score of 2 points.

[0099] Here, when the rain sensor detects snow or rain, weights can be assigned to environmental variables. These weights can then be adjusted based on the amount of snow or rain.

[0100] exist Figure 5 In one embodiment, weight 'x4' is assigned to standard 3 corresponding to the environment variable.

[0101] Therefore, for standard 2, data B is assigned one point and has a final illuminance score of 5, because the weight (x4) is applied to the one point assigned to standard 3.

[0102] therefore, Figure 2 The illuminance determination device 170 can select data B with the highest illuminance fraction as reference illuminance measurement data, and can determine the data to be applied based on the illuminance information of data B. Figure 1 Illuminance of 30 for a moving object.

[0103] Additionally, weights can be assigned to each reference time according to user settings.

[0104] In addition, it can be based on Figure 2 The weight learning device 160 uses the learning results to assign weights to each reference time. In this case, the weight learning device 160 can learn the weights of each item based on previous user settings.

[0105] refer to Figure 6 This describes an embodiment of an operation that reflects the results of calculating illuminance scores based on user-defined assigned weights or learning weights. Figure 6 This is a diagram illustrating an embodiment of the operation for calculating illuminance fractions, according to another embodiment of the present disclosure.

[0106] refer to Figure 6 , Figure 2 The illuminance fraction calculation device 150 can calculate the illuminance fraction of three illuminance measurement data, namely data A, data B and data C.

[0107] In this case, the illuminance score calculation device 150 can calculate the illuminance score based on some items included in each data point, such as measurement time, driving direction, weather information, vehicle type, sensor, and chromaticity.

[0108] Each reference item used to calculate illuminance score and Figure 4 The embodiments are the same.

[0109] Therefore, for standards 1, 5, and 6, data A is assigned one point each time, resulting in a final illuminance score of 3 points. For standards 2 and 3, data B is assigned one point each time, resulting in a final illuminance score of 2 points. For standards 2 and 4, data C is assigned one point each time, resulting in a final illuminance score of 2 points.

[0110] Here, weights can be assigned to each reference time based on user-defined weights or the results of learning user-defined weights.

[0111] exist Figure 6 In one embodiment, the weight 'x3' is assigned to the standard 3 corresponding to the environmental variable based on the results of user-defined or learned weights.

[0112] Therefore, for standard 2, data B is assigned 1 point, and the final illuminance score is 4 points, because the weight (x3) is applied to the one point assigned to standard 3.

[0113] therefore, Figure 2 The illuminance determination device 170 can select data B with the highest illuminance fraction as reference illuminance measurement data, and can determine the data to be applied based on the illuminance information of data B. Figure 1 Illuminance of 30 for a moving object.

[0114] The illuminance determination device 170 can compare the chromaticity of the moving object 30 with the chromaticity of reference illuminance measurement data. When the chromaticities are the same, the illuminance determination device 170 can determine the illuminance value of the reference illuminance measurement data as the illuminance to be applied to the moving object 30.

[0115] Simultaneously, the illuminance determination device 170 can compare the chromaticity of the moving object 30 with the chromaticity of reference illuminance measurement data. When the chromaticities differ from each other, the illuminance determination device 170 can adjust the illuminance to reflect the chromatic density of the moving object 30.

[0116] refer to Figure 7This describes an embodiment of the operation for determining illuminance with respect to chromaticity. Figure 7 This is a diagram illustrating an embodiment to which the operation of determining illuminance according to an embodiment of the present disclosure is referred.

[0117] Figure 7 The embodiment indication is based on being determined as Figure 6 The reference illuminance measurement data B determines the illuminance and adjusts the illuminance according to the chromaticity.

[0118] When the tinting density is dark, distortion may occur when measuring illuminance. Therefore, when the tinting density of data B and the tinting density of moving object 30 are different from each other, it is necessary to adjust the illuminance by reflecting the tinting density of data B and the tinting density of moving object 30 in the illuminance.

[0119] Therefore, refer to Figure 7 Since the chromaticity of the moving object 30 is 30%, and since the chromaticity of the data B used as the reference illuminance measurement data is 50%, distortion may occur when the illuminance value of data B is applied to the moving object 30 unchanged.

[0120] therefore, Figure 2 The illuminance determination device 170 can adjust the previously determined illuminance based on the chromaticity. At this time, when the chromaticity effect is removed from the illuminance value of data B and the chromaticity effect is applied to the moving object 30 to apply illuminance, the illuminance determination device 170 can obtain the illuminance that is basically identified in the target moving object 30.

[0121] For example, since data B has an illuminance of 5000 lux and a chromaticity of 50%, by removing 50% of the chromaticity from 5000 lux, it has an illuminance of 10000 lux.

[0122] At this point, when 30% of the shading effect of the target moving object 30 is given an illuminance of 10,000 lux, the illuminance at 30% shading becomes 7,000 lux.

[0123] Therefore, the illuminance determination device 170 can determine the adjusted illuminance of 7000 lux as the final illuminance to be applied to the target moving object 30.

[0124] When the illuminance is determined by the illuminance determining device 170 Figure 2 The controller 110 can adjust the screen brightness of the display based on the determined illuminance.

[0125] Thus, the screen control device 100 for a moving object according to an embodiment of the present disclosure can be used via... Figure 1Server 20 receives illuminance information and provides connected car services. Due to the structure of the illuminance sensor, a separate illuminance sensor is not required, saving costs. Screen control device 100 can also select the most suitable illuminance for the state of the moving object 30 from multiple illuminance information received from server 20 to adjust the display screen brightness to optimal levels.
