[Brief explanation of the drawings]

[0010] [Figure 1] 1 illustrates a vehicle equipped with a display control system according to an embodiment. [Figure 2] 2 illustrates an example of a functional configuration of the display control system of FIG. 1. [Figure 3] 3 shows an example of a user interface screen displayed by the display device of FIG. 2. [Figure 4] 3 shows another example of a user interface screen displayed by the display device of FIG. 2. DETAILED DESCRIPTION OF THE INVENTION

[0011] The following detailed description of exemplary embodiments will be given with reference to the accompanying drawings. In the drawings used in the following description, the scale has been appropriately changed so that the illustrated elements can be clearly seen.

[0012] FIG. 1 illustrates a vehicle 20 equipped with a display control system 10 according to an embodiment. The vehicle 20 is an example of a moving body. A plurality of seats are installed in a passenger compartment 21 of the vehicle 20. The plurality of seats includes a driver's seat 22 and a passenger seat 23. The driver's seat 22 is a seat in which the driver of the vehicle 20 sits. The passenger seat 23 is a seat in which a passenger sits.

[0013] A steering device 24 is disposed in front of the driver's seat 22 in the passenger compartment 21. The steering device 24 is a device for causing the vehicle 20 to perform an operation (steering operation) to change the direction of travel. The steering device 24 is configured to be operated by a driver seated in the driver's seat 22.

[0014] 2 illustrates a functional configuration of a display control system 10 according to an embodiment. The display control system 10 includes a display device 11. The display device 11 is mounted on a steering device 24. The display device 11 is an example of a first display device.

[0015] The display control system 10 includes a display control device 12. The display control device 12 includes an input interface 121, a processor 122, and an output interface 123.

[0016] The input interface 121 is configured as a hardware interface that receives status data ST from a processing device 30 mounted on the vehicle 20. The status data ST represents the status of the vehicle 20. The processing device 30 is configured to generate the status data ST based on information detected by a sensor 31 mounted on the vehicle 20.

[0017] The status data ST may be in the form of analog data or digital data depending on the communication specifications between the processing device 30 and the display control device 12. When the status data ST is in the form of analog data, the input interface 121 is provided with an appropriate conversion circuit including an A / D converter. This description also applies to other data and signals that can be accepted by the input interface 121, which will be described later.

[0018] Depending on the specifications of the sensor 31 and the type of detected information, the status data ST output from the sensor 31 may be directly received by the input interface 121.

[0019] The processor 122 is configured to output a display control signal DC, which causes the display device 11 to display a user interface screen (hereinafter abbreviated as "UI screen"), from the output interface 123. The UI screen is displayed to receive instructions for controlling the operation of the controlled device 40 mounted on the vehicle 20.

[0020] 3 illustrates an example of a UI screen 51 displayed on the display device 11. The UI screen 51 is configured to receive instructions for controlling the operation of a video and audio device as an example of the controlled device 40.

[0021] The output interface 123 is configured as a hardware interface capable of outputting a display control signal DC. The display control signal DC may be an analog signal or a digital signal depending on the specifications of the display device 11. When the display control signal DC is in the form of an analog signal, the output interface 123 includes an appropriate conversion circuit including a D / A converter. This description similarly applies to other signals that can be output by the output interface 123, which will be described later.

[0022] 2, the display device 11 is configured to output an instruction signal IS corresponding to an instruction from the driver received through the UI screen. The instruction signal IS may be an analog signal or a digital signal depending on the specifications of the display device 11.

[0023] The input interface 121 of the display control device 12 is configured to be able to also accept an instruction signal IS. Based on the instruction signal IS accepted by the input interface 121, the processor 122 outputs, from the output interface 123, an operation control signal OC for causing the controlled device 40 to perform an operation corresponding to the input instruction. The operation control signal OC may be an analog signal or a digital signal depending on the communication specifications between the display control device 12 and the processing device 30.

[0024] The processing device 30 controls the operation of the controlled device 40 based on the operation control signal OC. Depending on the specifications of the controlled device 40 and the type of the controlled operation, the operation control signal OC output from the output interface 123 may be input directly to the controlled device 40.

[0025] The processor 122 is configured to change the UI screen displayed on the display device 11 in accordance with the state of the vehicle 20 indicated by the state data ST received by the input interface 121. In other words, the processor 122 is configured to change instructions that can be accepted by the UI screen in accordance with the state of the vehicle 20 indicated by the state data ST.

[0026] For example, when status data ST indicating that the shift lever is in the "reverse" position is output from the processing device 30 based on the position of the shift lever detected by a shift sensor, which is an example of the sensor 31, the processor 122 outputs a display control signal DC, which causes the display device 11 to display a UI screen 52, as shown in FIG. 4, from the output interface 123. The UI screen 52 is configured to accept an instruction to adjust the angle of the rearview mirror. In this case, the rearview mirror angle adjustment device is an example of the controlled device 40.

[0027] As another example, when status data ST indicating that vehicle 20 is stopped and the shift lever is in the "parking" position is output from processing device 30 based on outputs of a shift sensor and a vehicle speed sensor as examples of sensors 31, processor 122 outputs a display control signal DC from output interface 123 to cause display device 11 to display a UI screen for receiving an instruction to start the drive source of vehicle 20. In this case, the drive source can be an example of controlled device 40.

[0028] As another example, when status data ST indicating that a seat belt is fastened is output from the processing device 30 based on the output of a seat belt sensor, which is an example of the sensor 31, the processor 122 outputs a display control signal DC, from the output interface 123, to cause the display device 11 to display a UI screen for receiving an instruction to start the drive source of the vehicle 20. A UI screen for receiving an instruction to adjust the position or posture of the driver's seat 22, the position of the steering device 24, etc. may be displayed. In this case, a starter for the drive source and various position adjustment devices can be examples of the controlled device 40.

[0029] As another example, when status data ST indicating that a window has been opened or closed is output from the processing device 30 based on the output of a switch sensor as an example of the sensor 31, the processor 122 outputs a display control signal DC, which causes the display device 11 to display a UI screen for receiving an instruction to cause the air conditioner to adjust the temperature, from the output interface 123. In this case, the air conditioner can be an example of the controlled device 40.

[0030] The types of functions, information, entertainment, and the like that can be provided in the vehicle 20 are constantly increasing. With this trend, the number of commands that need to be input to control the operation of the controlled device 40 is inevitably increasing. However, it is difficult to increase the number of user interfaces that can be installed in the limited space around the steering device 24, and to identify the required user interface from among the many user interfaces.

[0031] According to the configuration of this embodiment, a screen that provides a user interface for remotely controlling the operation of the controlled device 40 is displayed on the display device 11, and the screen is switched depending on the state of the vehicle 20. In other words, it is possible to respond to the diversification of controlled operations without changing the size of the area for providing the user interface. Since the display device 11 is mounted on the steering device 24 located at the driver's hand of the vehicle 20, it is possible to reduce the amount of work required to input instructions while eliminating the need to search for the required user interface. Therefore, it is possible to improve the convenience of a system that controls the operation of the controlled device mounted on the vehicle through a display device mounted on the steering device.

[0032] In particular, as in the examples described above, the UI screen displayed on the display device 11 changes in accordance with changes in the state of the vehicle 20 based on the actions of the occupants, providing the driver with a sense of comfort and the feeling that their actions are being supported.

[0033] As illustrated in FIG. 1, the vehicle 20 may include a meter display 25, a center display 26, and a sub-display 27.

[0034] The meter display 25 is installed at a position separated from the steering device 24. Specifically, the meter display 25 is installed in front of the steering device 24. The meter display 25 has a screen that can provide information such as the speed and mileage of the vehicle 20. The operation of the meter display 25 can be controlled through a UI screen displayed on the display device 11.

[0035] The center display 26 is installed at a position farther away from the steering device 24 than the meter display 25. Specifically, the center display 26 is installed at a position midway between the driver's seat 22 and the passenger seat 23. The center display 26 has a screen that can provide various types of information, such as map information and entertainment content, to both the driver and passengers. The operation of the center display 26 can also be controlled via a UI screen displayed on the display device 11.

[0036] The sub-display 27 is installed at a position farther away from the steering device 24 than the center display 26. Specifically, the center display 26 is installed in front of the passenger seat 23. The sub-display 27 has a screen that can provide various types of information, such as map information and entertainment content, to at least the passengers. The operation of the sub-display 27 can also be controlled through a UI screen displayed on the display device 11.

[0037] Any one of the meter display 25, the center display 26, and the sub-display 27 may not be installed. When the meter display 25 is installed, the meter display 25 is an example of a second display device, and each of the center display 26 and the sub-display 27 is an example of a third display device. When the meter display 25 is not installed, the center display 26 is an example of a second display device, and the sub-display 27 is an example of a third display device.

[0038] The status data ST output from the processing device 30 based on the detection result of a speed sensor, which is an example of the sensor 31, may include the travel speed of the vehicle 20. When the status data ST indicating that the travel speed exceeds a threshold is received by the input interface 121 of the display control device 12, the processor 122 may be configured to disable the reception of an instruction to control the operation of the third display device via the UI screen displayed on the display device 11.

[0039] As an example, if the meter display 25 is not installed and the status data ST indicates that the moving speed of the vehicle 20 exceeds a threshold value, the processor 122 disables the acceptance of instructions to control the operation of the sub-display 27 via the UI screen displayed on the display device 11.

[0040] As another example, when a meter display 25 is installed and the status data ST indicates that the moving speed of the vehicle 20 exceeds a threshold value, the processor 122 disables the acceptance of instructions to control the operation of the center display 26 or the sub-display 27 via the UI screen displayed on the display device 11.

[0041] For example, the input interface 121 of the display control device 12 may be prohibited from accepting an instruction signal IS output from the display device 11 based on an instruction from the driver input through a UI screen. Alternatively, the instruction signal IS accepted by the input interface 121 may be invalidated by the processor 122. In either case, the processor 122 may output, from the output interface 123, a display control signal DC that causes the display device 11 to display a screen notifying that operation is not possible. A display control signal DC may be output that hides or invalidates a UI screen related to an instruction that is deemed not to be acceptable.

[0042] According to this configuration, when the traveling speed of the vehicle 20 exceeds the threshold, it is impossible to remotely control the operation of display devices installed farther away from the steering device 24. Therefore, while ensuring the convenience of being able to remotely control the operation of multiple display devices installed in the passenger compartment 21 through the UI screen displayed on the display device 11 mounted on the steering device 24, it is possible to suppress the driver's line of sight movement when the traveling speed of the vehicle 20 exceeds the threshold, and encourage the driver to concentrate on driving operations.

[0043] The processor 122 of the display control device 12, which has the various functions described above, can be realized by at least one dedicated integrated circuit having a storage element in which a computer program for realizing the functions is pre-installed. Examples of the dedicated integrated circuit include a microcontroller, an ASIC, and an FPGA. The storage element is an example of a non-transitory computer-readable medium on which a computer program is stored.

[0044] The processor 122 may be realized by at least one general-purpose microprocessor operating in cooperation with at least one general-purpose memory. Examples of general-purpose microprocessors include a CPU, an MPU, and a GPU. Examples of general-purpose memory include a ROM and a RAM. In this case, a computer program for implementing the relevant functions may be stored in the ROM. The general-purpose memory is an example of a non-transitory computer-readable medium on which a computer program is stored. The general-purpose microprocessor specifies at least a portion of the program stored in the ROM, expands it in the RAM, and executes the above-described processing in cooperation with the RAM. The processor 122 may be realized by a combination of a dedicated integrated circuit and a general-purpose microprocessor.

[0045] The configurations referred to above are merely examples for facilitating understanding of the present disclosure. Each configuration example can be appropriately modified or combined with other configuration examples within the scope of the present disclosure.

[0046] The display control system 10 can also be mounted on a moving body other than the vehicle 20. Examples of such moving bodies include trains, ships, and aircraft. [Explanation of symbols]
