DETAILED DESCRIPTION

[0023] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0024] [1. Display Device and Vehicle Structure]

[0025] Figure 1 1 is a diagram showing the configuration of a vehicle 1 equipped with a display device 10 .

[0026] The display device 10 is a device having a display unit 40 for displaying text and images, and is mounted on a vehicle 1. The vehicle 1 is a vehicle capable of accommodating passengers and may be any vehicle other than a four-wheeled vehicle, a large vehicle, a commercial vehicle, or a work vehicle. Hereinafter, the occupants of the vehicle 1 will be referred to as passengers. One of the passengers is the driver who drives the vehicle 1. The vehicle 1 is a vehicle in which passengers other than the driver, i.e., fellow passengers, can ride.

[0027] The display device 10 is connected to a driving assistance device 100 .

[0028] The driving assistance device 100 is a device that performs autonomous driving of the vehicle 1, performing 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 the steering device 51, the braking device 52, and the 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 as a driving source of the vehicle 1, and includes a throttle device and a fuel injection device that control the operation of the driving source. The drive device 53 may also include a speed change mechanism that changes the output of the driving source. The steering device 51, the braking device 52, and the drive device 53 include actuators and motors as driving sources for operating the above-mentioned devices when the driver is not operating them.

[0029] Control device 110 is a computer comprising a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or other integrated circuit processor, and memory for storing programs and data. Control device 110 executes control programs 111 to control the operation of vehicle 1.

[0030] The sensor unit 120 includes sensors for the control device 110 to perform operation 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 the exterior of the vehicle 1. The radar unit 122 detects objects located outside the vehicle 1. The GPS sensor 123 determines the location of the vehicle 1 by receiving GPS signals using an antenna (not shown). The sensor unit 120 may also be provided with Figure 1 Sensors not shown in the figure may include, for example, a LiDAR (Light Detection And Ranging) unit. In addition, the sensor unit 120 may include various sensors such as a vehicle speed sensor included in the vehicle 1.

[0031] 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 representing detection values ​​from the sensor unit 120. Based on the detection data from the sensor unit 120, the control device 110 operates the steering device 51, the brake device 52, and the drive device 53.

[0032] Although not shown, the vehicle 1 includes a steering wheel 55 ( Figure 2 ), a brake pedal for operating the braking device 52, and an accelerator pedal for operating the drive device 53. They function as operating units for the driver to drive the vehicle 1. The driver can perform driving operations on the vehicle 1 by operating the steering wheel 55, the brake pedal, and the accelerator pedal. That is, the vehicle 1 is a vehicle that can switch between manual driving and automatic driving. The manual driving refers to driving according to the driver's driving operation, and the automatic driving refers to driving under the control of the driving assistance device 100 without the driver performing any driving operation. Hereinafter, whether the driving of the vehicle 1 is automatic driving or manual driving is referred to as the driving state of the vehicle 1. The steering wheel 55 is equivalent to an example of a steering operating unit.

[0033] The display device 10 includes a display unit 40. The display unit 40 is installed in the interior of the vehicle 1 and includes a display 41 and a touch sensor 42. The display 41 is composed of a liquid crystal display panel, an organic EL (electroluminescence) display panel, or other display panels, and displays text and images. The touch sensor 42 is a sheet-shaped sensor superimposed on the display surface of the display 41 and detects touch operations performed by a passenger. The touch sensor 42 is configured to cover substantially the entire display surface of the display 41, enabling detection of touch operations throughout the entire area of ​​the display 41 displaying text and images.

[0034] In the following description, the entire area of ​​the display 41 that can display images and text is referred to as the displayable area, and the entire area of ​​the touch sensor 42 that can detect operations is referred to as the detectable area. The displayable area is substantially the entire area excluding the outer frame of the display 41, and the touch sensor 42 substantially overlaps with the displayable area.

[0035] The display device 10 includes a CPU (Central Processing Unit) 20 and a memory 30 (equivalent to a storage unit) that stores programs and data executed by the CPU 20. The memory 30 is a nonvolatile storage device composed of a magnetic storage medium or a semiconductor memory element. The memory 30 stores, for example, a control program 31 and setting data 32.

[0036] The CPU 20 functions as a reception unit 21, a display control unit 22, and an area control unit 23 by reading and executing the control program 31. 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 causes the display 41 to display content. Here, the content includes text and images displayed on the display 41, and the content is not limited. For example, the content may be information related to the operating state of the vehicle 1, information related to the operation of the vehicle 1, maps related to the functions of the navigation device equipped in the vehicle 1, guidance information, movies, entertainment images broadcast on television, etc. The reception unit 21 is equivalent to an example of an operation unit, and the area control unit 23 is equivalent to an example of a control unit.

[0037] The area control unit 23 sets the display area on the display 41 and the operation area of ​​the touch sensor 42 for receiving operations. The area control unit 23 can set the display area to the entire displayable area of ​​the display 41 or to a portion 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 to a portion of the detectable area. The position and range of the display area and operation area set by the area control unit 23 are specified by, for example, the setting data 32.

[0038] The accepting unit 21 detects an operation within the operation area set by the area control unit 23 and does not accept a touch operation to a position outside the operation area.

[0039] 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 not to display characters and images in positions outside the display area.

[0040] The vehicle 1 is provided with a steering storage device 54. The steering storage device 54 is a device for moving a steering wheel 55, which is used for the driver of the vehicle 1 to perform steering operations. The steering storage device 54 has a support mechanism that supports the steering wheel 55 so that it can move, and a drive source such as a motor that causes the support mechanism to operate. When the vehicle 1 performs automatic driving based on the driving assistance device 100, the driver does not need to operate the steering wheel 55. In such a case, by using the steering storage device 54 to store the steering wheel 55, the driver can use a larger space in the cabin of the vehicle 1, thereby improving convenience. The steering storage device 54 is connected to the display device 10, and the display device 10 can operate the steering storage device 54 to move the steering wheel 55. In addition, the steering storage device 54 is connected to the driving assistance device 100, and the driving assistance device 100 can operate the steering storage device 54 to move the steering wheel 55.

[0041] [2. Configuration of equipment in the vehicle compartment]

[0042] Figure 2and Figure 3 These are perspective views of the main parts of an example of the structure inside the cabin 200 of the vehicle 1, showing the front portion of the cabin 200. In these figures, a configuration in which the driver's seat is provided on the right side of the cabin 200 is exemplified, but the present invention is also applicable to a vehicle 1 in which the driver's seat is provided on the left side of the cabin 200 by reversing the left and right sides.

[0043] A plurality of seats 230 for the passengers U of the vehicle 1 to sit are provided in the vehicle interior 200. Figure 2 In the structure, two seats 230 are arranged at the front of the vehicle 1 between the right door 210 of the vehicle 1 and the left door 220 of the vehicle 1. Of the two seats 230, seat 230A is the driver's seat for the driver U1 who drives the vehicle 1, and seat 230B is the front passenger seat for the passenger U2. That is, at the front of the vehicle 1, the driver's seat 230A for the driver U1 and the front passenger seat 230B (passenger seat) for the passenger U2 are arranged in a left-right arrangement. The steering wheel 55 is located in front of the seat 230A. In addition, hereinafter, when the driver U1 and the passenger U2 are not distinguished, they are recorded as passengers U.

[0044] The display unit 40 is provided on the instrument panel 201 at the front of the vehicle cabin 200. When the vehicle 1 is traveling in the forward direction, the display unit 40 has a laterally long displayable area and a detectable area extending in the left-right direction. Figure 2 In the structure, the display unit 40 is a so-called pillar-to-pillar type display that is provided over the substantially entire area between the pillar 242 on the right side of the front windshield 241 and the pillar 243 on the left side of the front windshield 241. In order to realize the pillar-to-pillar type structure, the display unit 40 is a structure in which a plurality of panels are connected. Specifically, the display unit 40 is formed by connecting a panel 40B horizontally arranged at the front center of the vehicle body 200, a panel 40C located to the right of the panel 40B, and a panel 40A located to the left of the panel 40B. The panels 40A, 40B, and 40C respectively include a display panel and a touch sensor 42 that constitute the display 41. The area control unit 23 can set the display area and the operation area in a manner that straddles the boundaries of the panels 40A, 40B, and 40C.

[0045] The display unit 40 extends from the front of the driver's seat 230A to the front of the passenger seat 230B. In the display unit 40, the area that overlaps with the front of the driver's seat 230A is designated as the driver's seat side area A1, and the area that overlaps with the front of the passenger seat 230B is designated as the passenger seat side area A2. The area between the driver's seat side area A1 and the passenger seat side area A2 is designated as the intermediate area A3. In other words, the driver's seat side area A1 is located in front of the driver U1, the passenger seat side area A2 is located in front of the passenger U2, and the intermediate area A3 is located between the driver U1 and the passenger U2.

[0046] The steering wheel 55 is supported by the steering receptacle 54. The steering wheel 55 is movable between a position operable by the driver U1 and a position away from the driver U1 by the operation of the steering receptacle 54. Here, the position of the steering wheel 55 where the driver U1 can operate the steering wheel 55 is referred to as the operated position, and the position away from the operated position is referred to as the non-operated position. The non-operated position can also be referred to as, for example, a position where the steering wheel 55 is away from the driver U1.

[0047] exist Figure 2 5 shows the steering wheel 55 in the operating position. Figure 3 The state where the steering wheel 55 is moved to the non-operating position is shown in FIG. Figure 3 As shown, the steering wheel 55 in the non-operating position is stored below the instrument panel 201 in a state of being tilted downward.

[0048] When the steering wheel 55 is moved to the non-operated position, a large space is created around the driver U1 in the vehicle interior 200, improving the ride quality of the vehicle interior 200. Furthermore, when the steering wheel 55 is in the non-operated position, the steering wheel 55 does not overlap the display unit 40 from the driver U1's perspective, allowing the driver U1 to visually recognize the display unit 40. Therefore, by moving the steering wheel 55 to the non-operated position while the vehicle 1 is traveling in automated driving, the comfort of the occupant U can be improved.

[0049] [3. Display area and operation area of ​​the display unit]

[0050] Figure 4 4 is a diagram showing a setting example of the display area and the operation area of ​​the display unit 40 , and shows an example of the display area and the operation area set by the area control unit 23 .

[0051] Figure 4 The driver's seat side area A1, the passenger seat side area A2 and the middle area A3 are reference Figure 2 The entire area A0 is the entire display unit 40. Specifically, the entire area A0 is the displayable area of ​​the display 41 in terms of the display area, and the entire area A0 is the entire detectable area of ​​the touch sensor 42 in terms of the operation area.

[0052] First area A11 is the area of ​​the entire area A0 excluding the passenger seat side area A2. In other words, first area A11 is the area of ​​the display unit 40 excluding the area in front of the passenger seat 230B. Second area A12 is the area of ​​the entire area A0 excluding the driver seat side area A1. In other words, second area A12 is the area of ​​the display unit 40 excluding the area in front of the driver seat 230A. It can be said that it is the area of ​​the display unit 40 excluding the area in front of the driver seat.

[0053] The area control unit 23 sets the display area and operation area based on the driving state of the vehicle 1, etc. For example, when the vehicle 1 is manually driven, the driver U1 operates the steering wheel 55, etc. to drive, so it is not appropriate for the driver U1 to perform touch operations on the display unit 40. In addition, the driver's seat side area A1 is not suitable for displaying entertainment images. Therefore, for example, when the vehicle 1 is manually driven, the area control unit 23 limits the display and operation in the driver's seat side area A1 by setting the display area and operation area to the second area A12. On the other hand, when the vehicle 1 is automatically driven, it is appropriate to use the entire display unit 40, including the driver's seat side area A1, for display and operation. Therefore, for example, when the vehicle 1 is automatically driven, the area control unit 23 sets the display area and operation area to the entire area A0.

[0054] Furthermore, when the steering wheel 55 is located in the operating position, the steering wheel 55 is located in front of the display unit 40 as viewed from the occupant U, thereby hindering the operation of the display unit 40 .

[0055] Therefore, the area control unit 23 appropriately sets and adjusts the display area and the operation area on the display unit 40 based on the driving state of the vehicle 1 and the position of the steering wheel 55. A specific example of setting the display area and the operation area will be described below.

[0056] [4. Operation of the display device]

[0057] [4-1. First Operation Example]

[0058] Figure 5 1 is a flowchart showing an operation example of the display device 10 , and shows a first operation example.

[0059] 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 a display area and an operation area based on the detection results.

[0060] Figure 5 Steps S1 to S6 are executed by the area control unit 23. Figure 5 The operation is repeatedly performed at a predetermined cycle while the display device 10 is activated.

[0061] The display device 10 determines whether the driving state of the vehicle 1 is manual driving (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.

[0062] When the driving state of the vehicle 1 is not manual driving, that is, when 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 ).

[0063] When 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 ).

[0064] When vehicle 1 is operating automatically, it is preferable to use the entire display unit 40 extensively for display, as this makes the display easier to see. In contrast, when steering wheel 55 is in the operating position, it is difficult for passenger U to operate the driver's seat area A1. Therefore, by defining an operating area other than driver's seat area A1, incorrect operations can be prevented, improving operability. Furthermore, when vehicle 1 is operating manually, restricting operations within driver's seat area A1 can prevent improper operations by driver U1 during driving. Furthermore, since operations within passenger's seat area A2 and center area A3 can be accepted, there is the advantage of not interfering with operations by fellow passenger U2.

[0065] [4-2. Second Operation Example]

[0066] Figure 6 1 is a flowchart showing an operation example of the display device 10 , and shows a second operation example.

[0067] 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 a display area and an operation area according to the change.

[0068] Figure 6 Steps S11 to S14 are executed by the area control unit 23. Figure 6 The action is executed during the startup of the display device 10, when the display device 10 detects a change in the position of the steering wheel 55, that is, an action of turning the storage device 54 as a trigger.

[0069] When the display device 10 detects movement of the steering wheel 55 (step S11), it determines whether the movement is from the use position to the non-use position (step S12). If the movement is from the use position to the 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 passed since the steering wheel 55 has completed its movement (step S13).

[0070] When 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 ).

[0071] When the steering wheel 55 is moved to the non-use position, it is preferable to use the entire display unit 40 for displaying information, as this makes the display easier to see. In contrast, 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 removing the driver's seat side area A1 from the operating area, erroneous operations can be prevented, improving operability.

[0072] [4-3. Third Operation Example]

[0073] Figure 7 1 is a flowchart showing an operation example of the display device 10 , and shows a third operation example.

[0074] 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 a display area and an operation area according to the change.

[0075] Figure 7 Steps S21 to S23 are executed by the area control unit 23. Figure 7 The operation is executed while the display device 10 is activated, triggered by the display device 10 detecting a change in the driving state of the vehicle 1 .

[0076] When the display device 10 detects that the driving state of the vehicle 1 has switched from automatic driving to manual driving (step S21), it changes the operating 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).

[0077] In the third operational example, as the driving assistance device 100 switches from automated driving to manual driving, the display area of ​​the display unit 40 switches to an area other than the driver's seat area A1. This allows the driver U1 to gradually recognize the switch from automated driving to manual driving. Furthermore, when the display area of ​​the display unit 40 is changed, the change in the operating area is complete, thus reliably preventing driver U1 from making erroneous operations.

[0078] [4-4. Fourth Operation Example]

[0079] Figure 8 1 is a flowchart showing an operation example of the display device 10 , and shows a fourth operation example.

[0080] 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 a display area and an operation area according to the change.

[0081] Figure 8 Steps S21 to S23 are Figure 7 In addition, step S24 is executed by the area control unit 23. Figure 8 The operation is executed while the display device 10 is activated, triggered by the display device 10 detecting a change in the driving state of the vehicle 1 .

[0082] When the display device 10 detects that the driving state of the vehicle 1 has switched from manual driving to automatic driving (step S21), it changes the operating 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).

[0083] Then, 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 ).

[0084] In the fourth action example, as the driver U1 switches from autonomous driving to manual driving using the driving assistance device 100, 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 use position. This allows the driver U1 to recognize the switch from autonomous driving to manual driving in stages. Furthermore, in the fourth action example, the display device 10 controls the steering storage device 54. The movement of the steering wheel 55 occurs after the changes in the operating area and display area are completed. Therefore, when the driver U1 is able to operate the steering wheel 55, the driver's seat side area A1 is removed from the operating area and display area. Therefore, the display can be provided in a manner that does not interfere with the operation of the steering wheel 55, preventing the driver U1 from making erroneous operations.

[0085] The first operation example and the second operation example can be executed in combination. In addition, the third operation example and the fourth operation example can be executed alternatively, and either the third operation example or the fourth operation example can be executed in combination with the first operation example and the second operation example.

[0086] [5. Other Implementation Methods]

[0087] The above-described embodiment is merely one embodiment of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.

[0088] The configuration of the steering wheel storage device 54 and steering wheel 55 shown in the above embodiment is merely an example. For example, the steering wheel storage device 54 may be configured to fold and store the steering wheel 55, or it may be configured to completely house the steering wheel 55 within the instrument panel 201. Alternatively, the steering wheel storage device 54 may be configured to move between a use position and a non-use position by changing the angle of the steering wheel 55. Alternatively, the steering wheel storage device 54 may be configured to linearly move the steering wheel 55 toward and away from the driver's seat 230A.

[0089] Figure 1 This is a schematic diagram showing the structure of the display device 10 by dividing the main processing contents for easy understanding of the present invention. The structure of the display device 10 may also be divided into other parts. In addition, the processing of each component may be performed by one hardware unit or by multiple hardware units. Figures 5 to 8 The processing of each component shown may be executed by one program or by a plurality of programs.

[0090] [6. Structure supported by the above-mentioned embodiment]

[0091] The above-described embodiment supports the following structure.

[0092] (Structure 1) A display device, which is mounted on a vehicle and includes a display unit, wherein a driver's seat for a driver who drives the vehicle and a passenger seat for passengers of the vehicle are arranged in the vehicle, and the display unit extends from the driver's seat to the passenger seat.
