[0003] [Patent Document 1] JP 2003-025911 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when a driver in the front seat checks the situation in the rear seat while the vehicle is traveling, it is desirable for the driver to do so in a manner that places a minimal burden on the driver so as not to interfere with driving.

[0005] However, when a display for the front seats is installed on the instrument panel as in the technology described in Patent Document 1, the driver must look down from the front of the vehicle to check the display, which increases the amount of line-of-sight movement. Therefore, from the perspective of reducing the burden on the driver, it is possible to provide the display in front of and above the driver's seat, for example.

[0006] On the other hand, the area in front of and above the driver's seat is within the field of vision of the occupant while driving, and depending on the size of the display unit, the occupant may find it annoying.

[0007] SUMMARY OF THE PRESENT DISCLOSURE In consideration of the above, an object of the present invention is to provide a display device for a vehicle that can reduce the burden on a driver in the front seat when checking the situation in the rear seat. [Means for solving the problem]

[0068] The biometric information acquiring unit 104 acquires biometric information of the occupant P2 in the rear seat 31 using the biometric sensor 92. The biometric information acquiring unit 104 may also acquire biometric information of the occupant P1 in the driver's seat 30 using the biometric sensor 92.

[0069] The occupant position detection unit 106 detects the position of the occupant P2 in the rear seat 31 in the vehicle compartment 14 using the biosensor 92. For example, the occupant position detection unit 106 may detect the position where the occupant P2 sits by analyzing an image of the second camera 96 ​​that captures the rear seat 31. The occupant position detection unit 106 may also detect the position where the occupant P2 sits based on a signal detected by a pressure sensor or electrostatic sensor provided in the rear seat 31.

[0070] The drive control unit 108 determines the amount of deployment L of the display surface 42 of the first display unit 38 into the passenger compartment 14 based on the driving state of the vehicle 12, and controls the drive unit 44 to deploy the display surface 42. Note that, as shown in Fig. 3, the amount of deployment L of the display surface 42 means the extension length of the first display unit 38 from the roof trim 24.

[0071] When the driving state of the vehicle 12 is in a driving state (driving), the drive control unit 108 determines the deployment amount L so that the display surface 42 of the first display unit 38 is deployed within a range Z that does not invade the driver's effective field of vision, and deploys the display surface 42 into the passenger compartment 14.

[0072] 3, the range Z means an area between a plane V1 extending in the vehicle longitudinal direction and the vehicle width direction at a predetermined distance H1 from the seating reference point R toward the vehicle upper side, and a plane V2 extending in the vehicle longitudinal direction and the vehicle width direction at a predetermined distance H2 shorter than the distance H1 toward the vehicle upper side from the seating reference point R. This range Z is determined based on laws and regulations for each country or region where the vehicle 12 is located, and the deployment amount management table 80A stored in the storage 80 associates a predetermined country or region with a corresponding value of the deployment amount L within a range that does not enter the range Z.

[0073] That is, when the driving state of the vehicle 12 is a traveling state (driving), the drive control unit 108 refers to the acquired position information of the vehicle 12 and the deployment amount management table 80A stored in the storage 80 to determine the deployment amount L of the display surface 42. This allows the display surface 42 to be deployed within a range that does not obstruct the driver's field of vision while driving.

[0074] The amount of deployment L of the display surface 42 may be set to a different value for each of the driving state, temporary stop state, and stopped state of the vehicle 12. For example, as shown in Fig. 4, when the driving state of the vehicle 12 is a driving state, the amount of deployment L is set to L1. When the vehicle is temporarily stopped, the amount of deployment L is set to L2, which is larger than L1. When the vehicle is stopped, the amount of deployment L is set to L3, which is larger than L2. In this way, when the driver is not involved in driving the vehicle 12, the amount of deployment L can be increased to make the display easier to see.

[0075] In this case, the temporary stop state of the vehicle 12 refers to, for example, a state in which the vehicle 12 is stopped for a predetermined period of time or more with an ignition switch (not shown) of the vehicle 12 turned ON. Also, the stopped state of the vehicle 12 refers to a state in which the vehicle 12 is stopped with the ignition switch turned OFF. Also, without being limited thereto, for example, it may be determined that the vehicle 12 is in a temporary stop state when it is determined that the vehicle 12 is stopped at a traffic light based on information acquired from the external sensor 88B.

[0076] Also, as one example, the deployment amounts L1 and L2 in the traveling state and the stopped state may be set to values ​​within a predetermined range (outside range Z) set in the country or region in which the vehicle 12 is located, as described above, and the deployment amount L3 in the stopped state may be set to a value beyond the predetermined range (inside range Z). Furthermore, even when the driving mode of the vehicle 12 is the autonomous driving mode, the deployment amount L of the display surface 42 may be set to L3.

[0077] In addition, the deployment amount L of the first display unit 38 may be configured so that the driver can set it to any value within a predetermined range set in the country or region in which the vehicle 12 is located by operating an operating unit not shown.

[0078] The display control unit 110 has a function of displaying various information on the first display unit 38. In this case, the display control unit 110 displays the various information so as to fit the deployment amount L of the display surface 42 of the first display unit 38. In other words, the display control unit 110 displays the various information so as to fit the exposed area of ​​the display surface 42 facing the inside of the vehicle interior 14.

[0079] As an example, the display control unit 110 displays a rear seat image 200 captured by the second rear seat camera 96 ​​on the display surface 42. This allows the occupant P1 in the driver's seat 30 to check the state of the rear seat 31 by looking at the first display unit 38, without moving his or her line of sight while driving.

[0080] Here, the display control unit 110 identifies the camera that captured the image of the occupant P2 from among the multiple second cameras 96 based on the position of the occupant P2 in the rear seat 31 detected by the occupant position detection unit 106, and displays the rear seat image 200 captured by the identified second camera 96 ​​on the display surface 42. This allows the first display unit 38 to reliably display the state of the occupant P2.

[0081] Furthermore, the display control unit 110 displays the rear seat image 200 in an area of ​​the display surface 42 corresponding to the position of the occupant P2 in the vehicle interior 14. That is, when the occupant P2 is seated in the rear seat 31 provided on the right side in the vehicle width direction in the vehicle interior 14, the rear seat image 200 of the occupant P2 is displayed in the right area of ​​the display surface 42.

[0082] 7 shows an example of a rear seat image 200 displayed on the display surface 42 unfolded from the roof trim 24. As shown in this figure, the rear seat image 200 of the occupant P2 in the rear seat 31 provided on the right side of the vehicle interior 14 is displayed in the right region 42R of the display surface 42. Also, the rear seat image 200 of the occupant P2 in the rear seat 31 provided on the left side of the vehicle interior 14 is displayed in the left region 42L of the display surface 42. By displaying in this manner, the occupant P1 in the driver's seat can intuitively grasp the positional relationship with the rear seat occupant P2 in the space within the vehicle interior 14 from the display surface 42 and can check the state of the rear seat.

[0083] Furthermore, the display control unit 110 displays the rear seat image 200 when predetermined biometric information is acquired from the biometric information of the occupant P2. Here, the predetermined biometric information is, for example, biometric information that exceeds a threshold value that is preset according to the type of biometric information. As an example, when the biometric information is the voice of the occupant P, it is a case where the occupant P speaks at a volume that exceeds a predetermined threshold. Also, when the biometric information is the movement of the occupant P2, it is a case where an amount of movement of the occupant P that exceeds a predetermined threshold is detected. However, without being limited to this, the predetermined biometric information may be a call from the occupant P2, a specific gesture, a specific facial expression of the occupant P2, etc.

[0084] In this embodiment, the display mode of the first display unit 38 can be set from among a lighting mode, a standard information display mode, and a mirror mode by the occupant P1 operating an operation unit (not shown). When the display mode is set, the support information 300 set according to the display mode is displayed on the first display unit 38.

[0085] Here, the display control unit 110 displays the support information 300 of each display mode alongside the rear seat image 200 on the first display unit 38. At this time, the support information 300 is displayed on the display surface 42 while maintaining the display areas (42R, 42L) of the rear seat image 200 displayed in association with the seating position of the occupant P2. For example, when the occupant P2 is seated in both the rear seat 31 on the right side and the rear seat 31 on the left side in the vehicle width direction, the support information is displayed between the right area 42R and the left area 42L on the display surface 42.

[0086] 8 shows a display example when the display mode is set to the illumination mode. As shown in this figure, in the illumination mode, the first display unit 38 functions as an illumination by illuminating a part of the display surface 42 with a luminance set by the occupant P1. On the display surface 42, support information 300A is displayed as illumination light in a display area between the right area 42R and the left area 42L.

[0087] FIG. 9 shows a display example when the display mode is set to the standard information display mode. As shown in this figure, in the standard display mode, time information and setting information of various in-vehicle devices are displayed on the first display unit 38. As an example, the display surface 42 displays the current time and support information 300B related to the setting information of the air conditioner in a display area between the right area 42R and the left area 42L. Note that this standard information display mode can be set to the normal state of the first display unit 38. When the standard information display mode is set to the normal mode, the first display unit 38 is configured to be in the standard information display mode when an ignition switch (not shown) is turned ON. On the other hand, when the ignition switch is turned OFF, the first display unit 38 is in a housed state in which the entire first display unit 38 is housed inside the roof trim 24.

[0088] Although not shown, in the standard information display mode, messages such as "WELCOME" and "HAPPY BIRTHDAY" for the occupant P1 may be displayed as support information. Also, information regarding the locking of doors and the opening and closing of windows detected by the vehicle state detection sensor 90 may be displayed.

[0089] Fig. 10 shows a display example when the display mode is set to the mirror mode. As shown in this figure, the mirror mode is a mode in which a part of the display surface 42 functions as a mirror. Specifically, in the mirror mode, a driver's seat image 300C captured by the first camera 94 for the driver's seat is acquired, and a mirror image of the occupant P1 is displayed on the display surface 42. In Fig. 10, the driver's seat image 300C captured of the occupant P1 is displayed as support information in a display area between the right area 42R and the left area 42L of the display surface 42.

[0090] Supplementally, in this mirror mode, the left and right edges of the periphery of the display area in which the driver's seat image 300C is displayed are set as light-emitting portions 302, and serve as illumination without illuminating the occupant P1.

[0091] Note that the support information supporting the occupant P1 in the driver's seat is not limited to the above-mentioned information, and may be support information related to driving the vehicle 12 or warning information for avoiding danger. For example, as shown in Fig. 11, when an external sensor 88B constituted by a camera or the like that captures an image of the rear of the vehicle 12 detects a sudden approach of a rear vehicle, a rear image 300D capturing an image of the rear vehicle Q may be displayed as support information to warn the occupant P1.

[0092] On the other hand, although not shown, the display control unit 110 can display the rear seat image 200 of the occupant P2 on the first display unit 38, and can simultaneously display the driver's seat image 300C of the occupant P1 in the driver's seat 30 on the second display unit 98 disposed on the front side of the rear seat 31. This allows the occupants P1 and P2 to check each other's condition by looking at the first display unit 38 and the second display unit 98.

[0093] (action) Next, the operation of this embodiment will be described. An example of a display process executed by the control unit 40 at a predetermined time cycle is shown in a flowchart in Fig. 12. This display process is executed by the CPU 74 reading a program from the ROM 76 or storage 80, and expanding the program in the RAM 78.

[0094] (Display processing) 12, in step S100, the CPU 74 acquires biometric information of the occupant P2 in the rear seat 31 based on the function of the biometric information acquisition unit 104, and determines whether or not the acquired biometric information includes predetermined biometric information. If the CPU 74 determines that the predetermined biometric information is included, it proceeds to processing in step S101. If the CPU 74 determines that the predetermined biometric information is not included, it ends the processing.

[0095] In step S101 , the CPU 74 acquires driving information of the vehicle 12 based on the function of the driving state acquisition unit 100 .

[0096] In step S102, the CPU 74 acquires the position information of the vehicle 12 based on the function of the position information acquisition unit 102.

[0097] In step S103, the CPU 74 sets the deployment amount L of the display surface 42 of the first display unit 38 based on the function of the drive control unit 108. For example, when the driving state of the vehicle 12 is a traveling state, the deployment amount L of the display surface 42 is set within a range that does not obstruct the field of view of the occupant P1, with reference to the vehicle position information and the deployment amount management table 80A. At this time, when the first display unit 38 is in a stored state, the display surface 42 of the first display unit 38 is deployed into the passenger compartment 14 based on the function of the drive control unit 108.

[0098] In step S104, the CPU 74 acquires the position of the occupant P2 in the rear seat 31 based on the function of the occupant position detection unit .

[0099] In step S105, the CPU 74, based on the function of the display control unit 110, causes the first display unit 38 to display a rear seat image 200 of the occupant P2. At this time, the rear seat image 200 is displayed in a display area of ​​the display surface 42 corresponding to the position of the occupant P2 in the vehicle interior 14, as shown in Fig. 7. Furthermore, as shown in Figs. 8 to 11, when the display mode of the first display unit 38 is set, the CPU 74 causes support information 300 to be displayed alongside the rear seat image 200.

[0100] In step S106, the CPU 74 displays a driver's seat image 300C obtained by photographing the occupant P1 in the driver's seat 30 on the second display unit 98 disposed on the front side of the rear seat 31. After that, the CPU 74 ends the display process.

[0101] As described above, the vehicular display device 10 according to the present embodiment includes the first display unit 38, which is disposed in front of and above the driver's seat 30 and includes the display surface 42 that is configured to be retractable from the roof trim 24 in the vehicle compartment 14. The first display unit 38 drives the display surface 42 by the drive unit 44, and is capable of changing the amount of deployment L into the vehicle compartment 14. The vehicular display device 10 also includes a control unit 40 that controls the first display unit 38 and the drive unit 44. The control unit 40 includes a driving state acquisition unit 100, a drive control unit 108, and a display control unit 110, and the drive control unit 108 changes the amount of deployment L of the display surface 42 into the vehicle compartment 14 based on the driving state acquired by the driving state acquisition unit 100 by controlling the drive unit 44. Furthermore, the display control unit 110 causes the rear seat image 200 captured by the second camera 96 ​​for the rear seat to be displayed on the display surface 42 so as to match the amount of deployment L of the display surface 42.

[0102] As a result, the occupant P1 in the driver's seat 30 can check the state of the rear seat 31 by visually checking the first display unit 38 and by only moving his / her line of sight slightly. In addition, while driving, the deployment amount L of the display surface 42 can be adjusted so as not to block the view of the occupant P1 who is the driver, and the occupant P1 can be prevented from feeling annoyed while driving. In this way, the vehicle display device 10 can reduce the burden on the occupant P1 who is driving in the driver's seat 30 when checking the state of the rear seat 31.

[0103] In this embodiment, the deployment amount L of the display surface 42 while traveling is changed within a predetermined range set in the country or region in which the vehicle 12 is located, based on the location information of the vehicle 12 acquired by the location information acquisition unit 102. Therefore, the deployment position of the first display unit 38 can be set to comply with the laws and regulations of the country or region in which the vehicle 12 is located.

[0104] In this embodiment, the timing for displaying the rear seat image 200 on the display surface 42 is when the biometric information acquisition unit 104 acquires predetermined biometric information about the occupant P2 in the rear seat 31. Therefore, the occupant P1 in the driver's seat 30 can be prompted to check the first display unit 38 at an appropriate timing according to a change in the occupant P2 in the rear seat 31.

[0105] Furthermore, according to this embodiment, even if the first display unit 38 is housed inside the roof trim 24, the occupant P1 in the driver's seat 30 can be urged to actively check the first display unit 38 in response to changes in the behavior of the occupant P2 in the rear seat 31.

[0106] In this embodiment, the rear seat image 200 is displayed in an area of ​​the display surface 42 that corresponds to the position of the occupant P2 in the rear seat 31 in the vehicle interior 14. This allows the occupant P1 in the driver's seat 30 to intuitively grasp the position of the occupant P2 in the rear seat 31 in the space within the vehicle interior 14 from the display surface 42 by looking at the first display unit 38, and to check the state of the rear seat 31.

[0107] Furthermore, when displaying the support information 300 on the display surface 42, the support information 300 is displayed alongside the rear seat image 200 while maintaining the area in which the rear seat image 200 is displayed. This reduces the flickering of the display surface 42 when both the rear seat image 200 and the support information 300 are displayed, thereby reducing the annoyance felt by the occupant P1 in the driver's seat 30.

[0108] In addition, in this embodiment, when the rear seat image 200 is displayed on the first display unit 38, the driver's seat image 300C captured by the first camera 94 for the driver's seat is displayed on the second display unit 98 for the rear seat. This allows the occupant P1 in the driver's seat 30 and the occupant P2 in the rear seat 31 to check each other's condition, thereby facilitating communication.

[0109] Furthermore, in this embodiment, based on the function of the display control unit 110, the second camera 96 ​​that captured the image of the occupant P2 in the rear seat 31 is identified from among the multiple second cameras 96 for the rear seats, and the image captured by the identified second camera is displayed on the first display unit 38. Therefore, even if multiple second cameras 96 for the rear seats are installed, such as when there are multiple rear seats 31 in the vehicle interior 14, the occupant P2 in the rear seat 31 can be reliably displayed on the first display unit 38.

[0110] In this embodiment, the first display unit 38 includes an organic electroluminescence element and is in the form of a film, and can be bent and deformed when storing the first display unit 38. This can reduce the installation space for the first display unit. [supplementary explanation]

[0111] In the above embodiment, the function of the display control unit 110 has been described as specifying a second camera that captures an image of the rear seat occupant P2 from among the multiple second cameras 96 for the rear seats, and displaying an image captured by the specified second camera 96 ​​on the first display unit 38. However, the present disclosure is not limited to this.

[0112] (First Modification of Display Control Unit 110) 13, the display control unit 110 is configured to be able to control the driving of an actuator 400 connected to the second camera 96, and may change the shooting range of the second camera 96 ​​so as to include the position of the occupant P2 detected by the occupant position detection unit 106 by controlling the driving of the actuator 400. Then, the image captured by the second camera 96 ​​is displayed on the display surface 42 of the first display unit 38. As a result, even if there are multiple rear seats 31 in the vehicle interior 14, the actuator 400 can be controlled to capture images of the multiple rear seats 31 with a single second camera 96, so that the number of second cameras 96 to be mounted can be reduced.

[0113] (Second Modification of Display Control Unit 110) 14, the display control unit 110 may capture images of multiple rear seats 31 with the second rear seat camera 96, extract an area X corresponding to the position of the occupant P2 detected by the occupant position detection unit 106 from a rear seat image 200 captured by the second camera 96, and display the area X on the display surface 42. As a result, even if there are multiple rear seats 31 in the vehicle interior 14, the number of second cameras 96 mounted can be reduced by capturing images of the multiple rear seats with the second rear seat camera 96 ​​and extracting some of the captured images.

[0114] In the above embodiment, a device having a rack-and-pinion mechanism or a ball screw mechanism is used as the drive unit that moves the first display unit in and out of the interior member, but the mechanism that can be used for the drive unit is not limited to this. For example, a device having a pantograph mechanism may be used as the drive unit depending on the specifications of the vehicle 12, etc.

[0115] In the above embodiment, an organic electroluminescence display is used as the first display unit, but this is not limited to this. For example, a small liquid crystal display may be used as the first display unit depending on the specifications of the vehicle 12.

[0116] In the present embodiment, the vehicle is described as having one row of rear seats behind the driver's seat in the drawings, but the number of rear seats can be changed as appropriate depending on the specifications of the vehicle. Two or more rows of rear seats may be provided, and the vehicle display device according to the above embodiment and the modified example may be installed in the passenger compartment of a large vehicle such as a kindergarten bus.

[0117] In addition, in the above embodiment, the rear seat 31 has been described as an example of a vehicle seat that is pre-installed in the passenger compartment 14, but the definition of the rear seat in this disclosure is not limited to this, but is a broad concept that also includes a space where a wheelchair occupant can secure their wheelchair inside the passenger compartment.

[0118] In the above embodiment, the display process executed by the CPU after reading the software (program) may be executed by various processors other than the CPU. In this case, examples of the processor include a PLD (Programmable Logic Device) such as an FPGA (Field-Programmable Gate Array) whose circuit configuration can be changed after manufacture, and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit configuration designed exclusively for executing a specific process. The display process may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types (for example, a plurality of FPGAs, a combination of a CPU and an FPGA, etc.). The hardware structure of these various processors is, more specifically, an electric circuit that combines circuit elements such as semiconductor elements. In addition, in each of the above embodiments, the display processing program is pre-stored (installed) in a ROM or storage, but the present invention is not limited to this. The program may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disk Read Only Memory), a DVD-ROM (Digital Versatile Disk Read Only Memory), or a USB (Universal Serial Bus) memory. The program may also be downloaded from an external device via a network. [Explanation of symbols]
