Summary of the Invention
Problems to be Solved by the Invention
[0004] When the display in the vehicle is set to two-screen display, the size of each screen becomes small, so sufficient visibility cannot always be ensured. On the other hand, for example, it is conceivable to provide relatively large displays on each of the driver's side and the passenger's side. However, since the space in the vehicle interior is generally limited, this may not be realistic.
[0005] In addition, the operation of the in-vehicle device is performed by a touch panel type display or buttons arranged adjacent to the display. When different images are displayed on the driver's side and the passenger's side from one display, there is a concern that the operations on the display on the driver's side and the passenger's side may interfere with each other.
[0006] In view of such circumstances, an object of the present disclosure made is to be able to display different images on the driver's seat side and the passenger seat side using one display, and to prevent operations on the images on the driver's seat side and the passenger seat side from interfering with each other.
Means for Solving the Problems
[0007] An in-vehicle device according to an embodiment of the present disclosure for solving the above problems is an in-vehicle device provided in a vehicle, and includes a display capable of displaying a first image displayed toward the driver's seat and a second image displayed toward the passenger seat, a first operation unit provided on the driver's seat side for receiving an operation on the first image, a second operation unit provided on the passenger seat side for receiving an operation on the second image, and a control unit for generating the first image and the second image displayed on the display. When the control unit is displaying a navigation screen for guiding a driving route as the first image during running of the vehicle, it displays an editing screen of the driving route as the second image and receives an operation by the second operation unit.
[0008] An in-vehicle device according to another embodiment of the present disclosure for solving the above problems is an in-vehicle device provided in a vehicle, and includes a display capable of displaying a first image displayed toward the driver's seat and a second image displayed toward the passenger seat, a first operation unit provided on the driver's seat side for receiving an operation on the first image, a second operation unit provided on the passenger seat side for receiving an operation on the second image, a control unit for generating the first image and the second image displayed on the display, and a camera or a microphone disposed in the vehicle for receiving a designation as to which of the first operation unit and the second operation unit performs an operation. The control unit can set the first image and the second image to be the same image or different images. When the first image and the second image are the same image, it receives an operation of only one of the first operation unit and the second operation unit that has received the designation.
Effects of the Invention
[0009] According to the present disclosure, an in-vehicle device can be provided that can display different images on the driver's seat side and the passenger seat side using one display, and operations on the images on the driver's seat side and the passenger seat side do not conflict.

Embodiments for Carrying Out the Invention
[0011] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.
[0012] An in-vehicle device 10 according to an embodiment of the present disclosure is a device such as a navigation device mounted on a vehicle such as a passenger car. FIG. 1 is a view of the arrangement of each component of the in-vehicle device 10 as seen from above. As shown in FIG. 1, the in-vehicle device 10 includes a control unit 11, a display 12, a first operation unit 13, and a second operation unit 14. Further, the in-vehicle device 10 may include a camera 15 and a microphone 16. Furthermore, the in-vehicle device 10 may include various components according to the functions to be provided.
[0013] The control unit 11 is configured to include a single or a plurality of processors and memories. The processors include a general-purpose processor that executes programmed functions by loading a specific program, and a dedicated processor specialized for specific processing. As the dedicated processor, a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), etc. can be adopted. The memory can store the program executed by the processor, the information during the operation by the processor, etc. The memory and the processor are connected by bus lines such as a data bus and a control bus. The memory can include a ROM (read only memory), a RAM (Random Access Memory), a flash memory, etc. The RAM can include a DRAM (Dynamic Random Access Memory) and an SRAM (Static Random Access Memory).
[0014] The control unit 11 controls the entire in-vehicle device 10 and executes various information processes required for the in-vehicle device 10. For example, the in-vehicle device 10 further includes a GNSS (Global Navigation Satellite System) receiver that acquires position information and a storage device that stores map data, and the control unit 11 may provide a function as a navigation device that performs route guidance based on the position information and the map data. Further, the in-vehicle device 10 includes an antenna for broadcast reception, and the control unit 11 may have a function as a digital broadcast tuner. The control unit 11 generates image data of a first image 17 on the driver's seat 21 side and a second image 18 on the passenger seat 22 side for display on the display 12. The image generated by the control unit 11 may include, for example, a navigation image for guiding the vehicle route on a map, and video of contents such as a TV and a video.
[0015] The display 12 is, for example, a liquid crystal display (LCD), an organic EL (Electro-Luminescence) display, or an inorganic EL display. The display 12 is a directional display that can present different images to the driver's seat 21 and the passenger seat 22. The image displayed by the display 12 varies depending on the viewing angle. The display 12 is disposed on the dashboard and instrument panel of the vehicle, etc., and can display the first image 17 on the side of the driver's seat 21 and the second image 18 on the side of the passenger seat 22. As a technique for displaying two images in different directions, a known technique described in Patent Document 2, etc. can be adopted.
[0016] The display 12 can make the first image 17 and the second image 18 the same image or different images according to the selection of the driver and the passenger in the passenger seat 22, or according to a predetermined rule. For example, during the running of the vehicle, the first image 17 may be a navigation image and the second image 18 may be a TV image. Also, during running, the first image 17 may be a navigation image and the second image 18 may be a route editing image capable of setting and changing route guidance. For example, the passenger in the passenger seat 22 can search for and add detour points, etc. during the running of the vehicle. Also, for example, when the navigation image is being displayed on the first image 17 and the second image 18, if the driver operates the shift lever to put the gear in R (reverse), only the first image 17 may be switched to the image of the back monitor and / or the image of the around view monitor. The image of the around view monitor is an image of the vehicle viewed from directly above, generated by synthesizing images from a plurality of cameras. By doing so, even when the driver is about to park, the passenger in the passenger seat 22 can continue to view the navigation image.
[0017] The first operation unit 13 is provided on the steering wheel, the door on the driver's seat 21 side, the dashboard, etc., and receives operations on the first image 17. The second operation unit 14 is provided on the door on the passenger seat 22 side, the dashboard, etc., and receives operations on the first image 17. The first operation unit 13 and the second operation unit 14 may include push buttons assignable to image enlargement / reduction and video playback / stop / rewind, etc., and one or more physical keys such as a cross key or a stick for moving the pointer on the image.
[0018] The camera 15 is arranged to face the driver's seat 21 and / or the passenger seat 22 inside the vehicle. The image captured by the camera 15 is transmitted to the control unit 11. The control unit 11 can recognize specific actions of the driver and / or the passenger in the passenger seat 22 included in the image of the camera 15 through image processing.
[0019] The microphone 16 is arranged near the driver's seat 21 or the passenger seat 22 inside the vehicle, and detects the voices of the driver or the passenger in the passenger seat 22. The voice detected by the microphone 16 is converted into a voice signal and transmitted to the control unit 11. The control unit 11 can perform voice recognition processing.
[0020] When the control unit 11 is displaying the same image on the first image 17 and the second image 18, by processing the signals from the camera 15 and / or the microphone 16, it can receive the designation of which of the first operation unit 13 and the second operation unit 14 performs the operation. For example, when the driver makes a predetermined action such as waving a hand at the camera 15, the control unit 11 may determine that it has received the designation of an operation from the first operation unit 13. Also, for example, when the driver or a passenger speaks towards the microphone 16, such as saying "driver", the control unit 11 may determine that it has received the designation of an operation from the first operation unit 13. In this case, the control unit 11 invalidates the operation from the second operation unit 14 and receives only the operation on the image from the first operation unit 13.
[0021] With the above configuration, the in-vehicle device 10 can display different first image 17 and second image 18 on the driver's seat 21 side and the passenger seat 22 side respectively by adopting a display 12 with directivity. Since this method does not divide the display screen of the display 12 for use, the screen size can be maintained and the visibility will not decrease. Also, when the first image 17 and the second image 18 are different images respectively, the driver in the driver's seat 21 and the passenger in the passenger seat 22 can operate the first image 17 and the second image 18 independently of each other using the first operation unit 13 and the second operation unit 14 respectively.
[0022] For example, when the in-vehicle device 10 is displaying a navigation screen guiding the driving route as the first image 17 during the vehicle's travel, it can display an editing screen of the driving route as the second image 18. Since it is in the middle of traveling, the control unit 11 restricts the operation of the navigation screen by the first operation unit 13 while accepting the editing operation of the driving route by the second operation unit 14. The result of the editing operation of the driving route by the second operation unit 14 is also reflected in the navigation image of the first image 17. In this way, in order to ensure the safety during the vehicle's travel, the in-vehicle device 10 can accept the editing of the driving route by the passenger in the passenger seat 22 while restricting the operation of the first image 17 by the driver.
[0023] Also, when the first image 17 and the second image 18 displayed on the in-vehicle device 10 are the same image, the control unit 11 can receive a designation from the camera 15 or the microphone 16 as to which of the first operation unit 13 and the second operation unit 14 performs the operation. The control unit 11 accepts the operation of only one of the designated first operation unit 13 and second operation unit 14. Thereby, the operation performed by the driver in the driver's seat 21 from the first operation unit 13 and the operation performed by the passenger in the passenger seat 22 from the second operation unit 14 can be performed almost simultaneously, and as a result, it is possible to avoid the operation contents from conflicting or interfering with each other. Since the in-vehicle device 10 accepts the operation of only the designated first operation unit 13 or second operation unit 14, stable operation is possible without the driver or the passenger in the passenger seat 22 performing an unintended operation.
[0024] Note that the present invention is not limited only to the above-described embodiments, and numerous variations or modifications are possible. For example, the functions etc. included in each means, each step, etc. can be rearranged so as not to be logically contradictory, and it is possible to combine a plurality of means or steps, etc. into one or to divide them.
