DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0009] [1. Configuration of display device and vehicle] FIG. 1 is a diagram showing the configuration of a vehicle 1 equipped with a display device 10. As shown in FIG. The display device 10 is a device having a display unit 40 that displays characters and images, and is mounted on a vehicle 1. The vehicle 1 is a vehicle that can accommodate people, and may be a four-wheeled vehicle or any other vehicle, such as a large vehicle, a commercial vehicle, or a work vehicle. The occupants of the vehicle 1 will be referred to as occupants below. One of the occupants is the driver who drives the vehicle 1. The vehicle 1 is a vehicle that can accommodate occupants other than the driver, i.e., passengers.

[0010] The display device 10 is connected to a driving assistance device 100 . The driving assistance device 100 is a device that performs autonomous driving of the vehicle 1, and performs so-called automatic driving. The driving assistance device 100 includes a control device 110 and a sensor unit 120. The driving assistance device 100 is connected to a steering device 51, a braking device 52, and a drive device 53 of the vehicle 1. The steering device 51 includes a steering mechanism that steers the vehicle 1. The braking device 52 is a brake device of the vehicle 1. The drive device 53 includes a motor and an engine that are drive sources of the vehicle 1, and also includes a throttle device and a fuel injection device that control the operation of the drive source. The drive device 53 may also include a speed change mechanism that changes the output of the drive source. The steering device 51, the braking device 52, and the drive device 53 include actuators and motors as drive sources for operating the above devices without the driver's operation.

[0011] The control device 110 is a computer including a processor such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or other integrated circuit, and a memory for storing programs and data. The control device 110 executes a control program 111 to control the operation of the vehicle 1.

[0012] The sensor unit 120 includes sensors used by the control device 110 to perform driving control. For example, the sensor unit 120 includes a camera 121, a radar unit 122, and a GPS (Global Positioning System) sensor 123. The camera 121 is a digital camera that captures images of the outside of the vehicle 1. The radar unit 122 detects objects located outside the vehicle 1. The GPS sensor 123 identifies the position of the vehicle 1 by receiving a GPS signal with an antenna (not shown). The sensor unit 120 may be provided with sensors not shown in FIG. 1 , and may include, for example, a LiDAR (Light Detection And Ranging) unit. The sensor unit 120 may also include various sensors provided in the vehicle 1, such as a vehicle speed sensor.

[0013] The control device 110 executes the control program 111 to perform autonomous driving of the vehicle 1. For example, the control device 110 acquires detection data indicating detection values ​​of the sensor unit 120. The control device 110 operates the steering device 51, the braking device 52, and the drive device 53 based on the detection data of the sensor unit 120.

[0014] Although not shown, the vehicle 1 is equipped with a steering wheel 55 (FIG. 2) that operates the steering device 51, a brake pedal that operates the braking device 52, and an accelerator pedal that operates the drive device 53. These function as operation units that allow the driver to drive the vehicle 1. The driver can drive the vehicle 1 by operating the steering wheel 55, the brake pedal, and the accelerator pedal. In other words, the vehicle 1 is a vehicle that can switch between manual driving, in which the vehicle travels according to the driving operations of the driver, and automatic driving, in which the vehicle travels without the driver performing any driving operations under the control of the driving assistance device 100. Whether the vehicle 1 is being driven automatically or manually is hereinafter referred to as the driving state of the vehicle 1. The steering wheel 55 corresponds to an example of a steering operation unit.

[0015] The display device 10 includes a display unit 40. The display unit 40 is installed in the passenger compartment of the vehicle 1 and includes a display 41 and a touch sensor 42. The display 41 is configured with a display panel such as a liquid crystal display panel or an organic EL (Electro Luminescence) panel, and displays characters and images. The touch sensor 42 is a sheet-like sensor superimposed on the display surface of the display 41, and detects touch operations by the occupant. The touch sensor 42 is arranged to cover almost the entire display surface of the display 41, and can detect touch operations over the entire area where the display 41 displays characters and images.

[0016] In the following description, the entire area on display 41 where images and characters can be displayed is referred to as the displayable area, and the entire area on touch sensor 42 where operations can be detected is referred to as the detectable area. The displayable area is almost the entire display 41 excluding the outer frame, and touch sensor 42 almost overlaps with the displayable area.

[0017] The display device 10 includes a CPU (Central Processing Unit) 20 and a memory 30 (corresponding to a storage unit) that stores programs and data executed by the CPU 20. The memory 30 is a non-volatile storage device configured from a magnetic storage medium or a semiconductor storage element. The memory 30 stores, for example, a control program 31 and setting data 32.

[0018] The CPU 20 loads and executes the control program 31, thereby functioning as a reception unit 21, a setting unit 22, and an area control unit 23. The reception unit 21 detects an operation on the touch sensor 42 and receives input based on the detected operation. The display control unit 22 displays content on the display 41. Here, the content includes characters and images displayed on the display 41, and the content is not limited. For example, the content may be information about the operating state of the vehicle 1, information about the operation of the vehicle 1, maps and guidance information related to the functions of a navigation device provided in the vehicle 1, entertainment videos from movies or television broadcasts, etc. The reception unit 21 corresponds to an example of an operation unit, and the area control unit 23 corresponds to an example of a control unit.

[0019] The area control unit 23 sets a display area on the display 41 and an operation area in which the touch sensor 42 accepts operations. The area control unit 23 can set the display area to the entire displayable area of ​​the display 41 or a part of the displayable area. The area control unit 23 can set the operation area to the entire detectable area of ​​the touch sensor 42 or a part of the detectable area. The positions and ranges of the display area and operation area set by the area control unit 23 are specified by, for example, setting data 32.

[0020] The reception unit 21 detects operations in the operation area set by the area control unit 23, and does not receive touch operations at positions outside the operation area. The display control unit 22 causes the display 41 to display characters and images in the display area set by the area control unit 23, and does not cause them to be displayed in positions outside the display area.

[0021] The vehicle 1 is equipped with a steering retractable device 54. The steering retractable device 54 is a device that moves a steering wheel 55 used by the driver of the vehicle 1 to perform steering operation. The steering retractable device 54 has a support mechanism that movably supports the steering wheel 55 and a drive source such as a motor that operates the support mechanism. When the vehicle 1 is driven automatically by the driving assistance device 100, the driver does not need to operate the steering wheel 55. In such a case, by retracting the steering wheel 55 using the steering retractable device 54, the driver can use more space in the cabin of the vehicle 1, thereby improving convenience. The steering retractable device 54 is connected to the display device 10, and the display device 10 can operate the steering retractable device 54 to move the steering wheel 55. The steering retractable device 54 is also connected to the driving assistance device 100, and the driving assistance device 100 can operate the steering retractable device 54 to move the steering wheel 55.

[0022] [2. Placement of equipment in the vehicle cabin] 2 and 3 are perspective views of the main part showing an example of the configuration inside the cabin 200 of the vehicle 1, showing the front part of the cabin 200. These figures illustrate a configuration in which the driver's seat is provided on the right side of the cabin 200, but by reversing the left and right, the present invention can also be applied to a vehicle 1 in which the driver's seat is provided on the left side of the cabin 200.

[0023] A plurality of seats 230 for occupants U of the vehicle 1 are provided in the vehicle compartment 200. In the configuration of FIG. 2, two seats 230 are arranged in the front of the vehicle 1 between a right door 210 and a left door 220 of the vehicle 1. Of the two seats 230, seat 230A is a driver's seat in which a driver U1 who drives the vehicle 1 is seated, and seat 230B is a passenger seat in which a passenger U2 is seated. In other words, in the front of the vehicle 1, the driver's seat 230A in which the driver U1 sits and the passenger seat 230B (passenger seat) in which the passenger U2 sits are arranged side by side. A steering wheel 55 is located in front of seat 230A. In the following, when there is no need to distinguish between the driver U1 and the passenger U2, they will be referred to as occupants U.

[0024] The display unit 40 is installed on the dashboard 201 in the front part of the vehicle interior 200. When the vehicle 1 is traveling forward, the display unit 40 has a horizontally elongated displayable area and detectable area extending in the left-right direction. In the configuration shown in FIG. 2 , the display unit 40 is a so-called pillar-to-pillar display that is installed across almost the entire area between a pillar 242 on the right side of the windshield 241 and a pillar 243 on the left side of the windshield 241. To achieve the pillar-to-pillar configuration, the display unit 40 is configured by connecting multiple panels. Specifically, the display unit 40 is configured by connecting a panel 40B that is horizontally arranged in the center of the front part of the vehicle interior 200, a panel 40C located to the right of the panel 40B, and a panel 40A located to the left of the panel 40B. Each of the panels 40A, 40B, and 40C includes a display panel that constitutes the display 41 and a touch sensor 42. The area control unit 23 can set the display area and operation area so as to straddle the boundaries between the panels 40A, 40B, and 40C.

[0025] Display unit 40 extends from in front of driver's seat 230A to in front of passenger seat 230B. In display unit 40, the area overlapping the front of driver's seat 230A is referred to as driver's side area A1, and the area overlapping the front of passenger seat 230B is referred to as passenger's side area A2. The area between driver's side area A1 and passenger's side area A2 is referred to as intermediate area A3. In other words, driver's side area A1 is located in front of driver U1, passenger's side area A2 is located in front of passenger U2, and intermediate area A3 is located between driver U1 and passenger U2.

[0026] The steering wheel 55 is supported by a steering storage device 54. The steering wheel 55 moves between a position where it can be operated by the driver U1 and a position away from the driver U1 by operation of the steering storage device 54. Here, among the positions of the steering wheel 55, a position where the driver U1 can operate the steering wheel 55 is called an operating position, and a position away from the operating position is called a non-operating position. The non-operating position can also be referred to as, for example, a position where the steering wheel 55 is away from the driver U1.

[0027] Fig. 2 shows a state in which the steering wheel 55 is in the operating position. Fig. 3 shows a state in which the steering wheel 55 has been moved to the non-operating position. In the non-operating position, the steering wheel 55 is stored below the dashboard 201 in a state in which it is tilted downward, as shown in Fig. 3, for example.

[0028] With the steering wheel 55 moved to the non-operated position, a large space is created around the driver U1 in the vehicle interior 200, improving the habitability of the vehicle interior 200. Furthermore, when the steering wheel 55 is moved to the non-operated position, the steering wheel 55 does not overlap the display unit 40 as seen from the driver U1, so the driver U1 can clearly see the display unit 40. Therefore, while the vehicle 1 is traveling by automatic driving, the comfort of the occupant U can be improved by moving the steering wheel 55 to the non-operated position.

[0029] [3. Display area and operation area of ​​the display] FIG. 4 is a diagram showing an example of setting the display area and operation area of ​​the display unit 40, and shows an example of the display area and operation area set by the area control unit 23.

[0030] The driver's seat side area A1, the passenger seat side area A2, and the intermediate area A3 in Fig. 4 are the areas described with reference to Fig. 2. The entire area A0 is the entire display unit 40. In detail, the entire area A0 is the displayable area of ​​the display 41 in terms of the display area, and is the entire detectable area of ​​the touch sensor 42 in terms of the operation area.

[0031] The first area A11 is an area of ​​the entire area A0 excluding the passenger seat side area A2. In other words, the first area A11 is an area of ​​the display unit 40 excluding the area in front of the passenger seat 230B. The second area A12 is an area of ​​the entire area A0 excluding the driver seat side area A1. In other words, the second area A12 is an area of ​​the display unit 40 excluding the area in front of the driver seat 230A, and can be said to be an area from the display unit 40 excluding the area in front of the driver's seat.

[0032] The area control unit 23 sets the display area and the operation area depending on the driving state of the vehicle 1, etc. For example, when the vehicle 1 is being driven manually, the driver U1 drives by operating the steering wheel 55, etc., and therefore it is not appropriate for the driver U1 to perform touch operations on the display unit 40. It is also not appropriate for entertainment videos to be displayed in the driver's seat side area A1. For this reason, for example, when the vehicle 1 is being driven manually, the area control unit 23 limits the display and operation in the driver's seat side area A1 by setting the display area and the operation area to the second area A12. On the other hand, when the vehicle 1 is being driven autonomously, it is preferable that the entire display unit 40, including the driver's seat side area A1, be used for display and operation. For this reason, for example, when the vehicle 1 is being driven autonomously, the area control unit 23 sets the display area and the operation area to the entire area A0.

[0033] Furthermore, when the steering wheel 55 is in the operating position, the steering wheel 55 is located in front of the display unit 40 as viewed from the occupant U, and therefore operation of the display unit 40 is hindered.

[0034] Therefore, the area control unit 23 appropriately sets and adjusts the display area and operation area on the display unit 40 based on the driving state of the vehicle 1 and the position of the steering wheel 55. Specific examples of setting the display area and operation area will be described below.

[0035] [4. Operation of the display device] [4-1. First operation example] FIG. 5 is a flowchart showing an example of the operation of the display device 10, and shows a first example of the operation. The first operation example is an operation in which the display device 10 detects the driving state of the vehicle 1 and the position of the steering wheel 55, and sets the display area and operation area according to the detection results.

[0036] Steps S1 to S6 in Fig. 5 are executed by the area control unit 23. Furthermore, the operation in Fig. 5 is repeatedly executed at predetermined intervals while the display device 10 is activated.

[0037] The display device 10 determines whether the driving state of the vehicle 1 is manual driving or not (step S1). If the vehicle 1 is manually driven (step S1: YES), the display device 10 sets the operation area and display area of ​​the display unit 40 to the second area A12 (step S2), and ends this process.

[0038] If the driving state of the vehicle 1 is not manual driving, that is, if the vehicle 1 is in automatic driving (step S1: NO), the display device 10 determines whether the steering wheel 55 is in the use position (step S3).

[0039] If the steering wheel 55 is in the use position (step S3: YES), the display device 10 sets the operation area to the second area A12 (step S4) and sets the display area to the entire area A0 (step S5).

[0040] When the vehicle 1 is driven automatically, it is preferable to display the entire display unit 40 in a large size, as this makes the display easier to see. On the other hand, when the steering wheel 55 is in the operating position, it is difficult for the occupant U to operate the driver's seat side area A1. Therefore, by setting an operating area excluding the driver's seat side area A1, it is possible to prevent erroneous operations and improve operability. Furthermore, when the vehicle 1 is driven manually, it is possible to prevent inappropriate operations by the driver U1 while driving by limiting operations in the driver's seat side area A1. Furthermore, since operations in the passenger's seat side area A2 and the intermediate area A3 can be accepted, there is an advantage in that they do not interfere with operations by the passenger U2.

[0041] [4-2. Second operation example] FIG. 6 is a flowchart showing an example of the operation of the display device 10, and shows a second example of the operation. The second operation example is an operation in which the display device 10 detects a change in the position of the steering wheel 55 and sets the display area and operation area in response to this change.

[0042] Steps S11 to S14 in Fig. 6 are executed by the area control unit 23. The operation in Fig. 6 is triggered by the display device 10 detecting a change in the position of the steering wheel 55, i.e., the operation of the steering storage device 54, while the display device 10 is running.

[0043] When the display device 10 detects movement of the steering wheel 55 (step S11), it determines whether the movement is from a use position to a non-use position (step S12). If the movement is from a use position to a non-use position (step S12: YES), the display device 10 changes the operation area of ​​the display unit 40 to the entire area A0 after a predetermined time has elapsed since the movement of the steering wheel 55 was completed (step S13).

[0044] If the movement of the steering wheel 55 is not from the use position to the non-use position (step S12: NO), the display device 10 sets the operation area to the second area A12 (step S14).

[0045] When the steering wheel 55 is moved to the unused position, it is preferable to display the display in a large size across the entire display unit 40. On the other hand, when the steering wheel 55 is in the operating position, it is difficult for the occupant U to operate the driver's seat side area A1, so by excluding the driver's seat side area A1 from the operating area, it is possible to prevent erroneous operation and improve operability.

[0046] [4-3. Third operation example] FIG. 7 is a flowchart showing an example of the operation of the display device 10, and shows a third example of the operation. The third operation example is an operation in which the display device 10 detects a change in the driving state of the vehicle 1 and sets the display area and operation area in response to this change.

[0047] Steps S21 to S23 in Fig. 7 are executed by the area control unit 23. The operation in Fig. 7 is triggered by the display device 10 detecting a change in the driving state of the vehicle 1 while the display device 10 is running.

[0048] When the display device 10 detects that the driving state of the vehicle 1 has been switched from manual driving to automatic driving (step S21), the display device 10 changes the operation area of ​​the display unit 40 to the second area A12 (step S22). After executing the change in step S22, the display device 10 changes the display area of ​​the display unit 40 to the second area A12 (step S23).

[0049] In the third operation example, as the driving assistance device 100 switches from automatic driving to manual driving, the display area of ​​the display unit 40 switches to an area excluding the driver's seat side area A1. This allows the driver U1 to gradually recognize that automatic driving is being switched to manual driving. When the display area of ​​the display unit 40 is changed, the change in the operation area has already been completed, so that erroneous operation by the driver U1 can be reliably prevented.

[0050] [4-4. Fourth operation example] FIG. 8 is a flowchart showing an example of the operation of the display device 10, and shows a fourth example of the operation. The fourth operation example is an operation in which the display device 10 detects a change in the driving state of the vehicle 1 and sets the display area and operation area in response to this change.

[0051] Steps S21 to S23 in Fig. 8 are the same as those in Fig. 7. Furthermore, step S24 is executed by the area control unit 23. The operation in Fig. 8 is triggered by the display device 10 detecting a change in the driving state of the vehicle 1 while the display device 10 is running.

[0052] When the display device 10 detects that the driving state of the vehicle 1 has been switched from manual driving to automatic driving (step S21), the display device 10 changes the operation area of ​​the display unit 40 to the second area A12 (step S22). After executing the change in step S22, the display device 10 changes the display area of ​​the display unit 40 to the second area A12 (step S23).

[0053] Furthermore, the display device 10 operates the steering storage device 54 to move the steering wheel 55 from the unused position to the used position (step S24).

[0054] In the fourth operation example, as the driving assistance device 100 switches from automatic driving to manual driving, the display area of ​​the display unit 40 switches to an area excluding the driver's seat side area A1, and the steering wheel 55 moves to the operating position. This allows the driver U1 to gradually recognize that automatic driving is switching to manual driving. Furthermore, in the fourth operation example, the display device 10 controls the steering retraction device 54. The movement of the steering wheel 55 is performed after the change of the operation area and the display area is completed. Therefore, when the driver U1 is able to operate the steering wheel 55, the driver's seat side area A1 is excluded from the operation area and the display area. This allows the display to be performed without interfering with the operation of the steering wheel 55, preventing erroneous operation by the driver U1.

[0055] The first and second operation examples can be executed in combination. The third and fourth operation examples can be executed alternatively, and either the third or fourth operation example can be executed in combination with the first and second operation examples.

[0056] 5. Other Embodiments The above embodiment is merely one embodiment of the present invention, and any modifications and applications are possible without departing from the spirit of the present invention.

[0057] The configurations of the steering storage device 54 and the steering wheel 55 shown in the above embodiment are merely examples. For example, the steering storage device 54 may be configured to fold and store the steering wheel 55, or may be configured to completely store the steering wheel 55 in the dashboard 201. The steering storage device 54 may also be configured to move the steering wheel 55 between an in-use position and an in-use position by changing the angle of the steering wheel 55. The steering storage device 54 may also be configured to move the steering wheel 55 linearly in a direction toward the driver's seat 230A and a direction away from the driver's seat 230A.

[0058] 1 is a schematic diagram showing the configuration of display device 10 divided by main processing content to facilitate understanding of the present invention, but the configuration of display device 10 may be divided in other ways. Furthermore, the processing of each component may be performed by one hardware unit or multiple hardware units. Furthermore, the processing of each component shown in FIGS. 5 to 8 may be performed by one program or multiple programs.

[0059] [6. Configurations Supported by the Above-mentioned Embodiments] The above embodiment supports the following configurations.
