[0001] The present invention relates to a display device for a vehicle. [Background technology]

[0002] The following Patent Document 1 discloses an invention related to a display system. In this display system, a vehicle performing autonomous driving is provided with a front display that can be switched between a front-shielded state in which a screen is displayed in a position that blocks the driver's forward view, and a non-front-shielded state in which a screen is displayed in a different position that does not block the driver's forward view. This front display is in the front-shielded state when the vehicle is in autonomous driving, and in the non-front-shielded state when the vehicle switches from autonomous driving to manual driving. This allows the driver to quickly grasp surrounding traffic information when the driving mode switches from autonomous driving to manual driving. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-196228 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the case of the configuration disclosed in Patent Document 1, the driver cannot recognize in advance that the driving mode will be switched from automatic to manual, and there is a possibility that the driver will be delayed in responding.

[0005] 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 allows a driver to recognize in advance that a driving mode will be switched. [Means for solving the problem]

[0006] The vehicle display device of the invention described in claim 1 has a judgment unit that judges whether a driving mode switch will occur within a predetermined period of time, and a display control unit that gradually changes the display area of ​​information before the driving mode switch occurs when the judgment unit judges that the driving mode will switch from autonomous driving to manual driving within the predetermined period of time, or when the judgment unit judges that the driving mode will switch from manual driving to autonomous driving within the predetermined period of time.

[0007] According to the invention described in claim 1, the determination unit determines whether or not a driving mode switch will occur within a predetermined period. Furthermore, when it is determined that a driving mode switch will occur from automatic driving to manual driving within the predetermined period, or when it is determined that a driving mode switch will occur from manual driving to automatic driving within the predetermined period, the display control unit gradually changes the display area of ​​the information before the driving mode switch occurs. By changing the display area of ​​the information in advance in this manner, the driver can recognize the driving mode switch in advance. Effect of the Invention

[0008] The vehicle display device according to the invention recited in claim 1 has an excellent effect of allowing the driver to recognize in advance that the driving mode will be switched. [Brief description of the drawings]

[0010] (First embodiment) A first embodiment of a display device for a vehicle according to the present invention will be described below with reference to Figures 1 to 4. In each drawing, the same or equivalent components and parts are given the same reference symbols. Also, the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios.

[0011] (Overall composition) FIG. 1 is a diagram showing a schematic configuration of a vehicle display device according to a first embodiment.

[0012] As shown in FIG. 1, the display device 10 for a vehicle includes a control device 14 mounted on a vehicle 12 capable of automatic driving, and a display device 16. The vehicle 12 is provided with a driving control unit 18 that controls the automatic driving of the vehicle 12 and switches between automatic driving and manual driving. The driving control unit 18 is connected to, for example, a surrounding situation acquisition unit, a vehicle driving state acquisition unit, a map information storage unit, and an input unit (all not shown). In order to automatically drive the vehicle 12, the driving control unit 18 performs automatic driving control by determining the vehicle 12 and its surrounding situation based on route information in a map information storage unit that stores information obtained from a navigation system and information obtained from various sensors (all not shown), and controls the amount of acceleration, the amount of braking, the steering angle, and the like to the destination. That is, the driving control unit 18 performs automatic driving of the vehicle 12 by controlling the vehicle based on the surrounding situation of the vehicle detected by the surrounding situation acquisition unit. Note that the automatic driving control by the driving control unit 18 is publicly known, for example, in JP 2008-123197 A, and therefore a detailed description thereof will be omitted.

[0013] When automatic driving is stopped due to surrounding road conditions or an operation by the driver during automatic driving, the driving control unit 18 switches to manual driving by the driver. In other words, the driving subject is handed over (handed over) from the vehicle 12 to the driver.

[0014] The control device 14 has a determination unit 20 and a display control unit 22 (see FIG. 3), of which the determination unit 20 determines the current driving mode (automatic driving or manual driving) of the vehicle 12 based on the operation information of the driving control unit 18, and whether or not to transition from automatic driving to manual driving or from manual driving to automatic driving. In addition, the display control unit 22 performs display on the display device 16 based on the determination result of the determination unit 20. The specific configuration and operation of the control device 14 will be described later.

[0015] The display device 16 has a display unit 23 (see FIG. 3) and displays information toward the interior of the vehicle in a display method (display size) determined by the control device 14 as the determination unit 20 (see FIG. 3). The specific configuration and operation of the display device 16 will be described later.

[0016] The vehicle display device 10 also communicates with an external server 24 and the like via a network N such as a mobile phone communication network. A specific configuration and operation of this communication will be described later.

[0017] (Hardware configuration) FIG. 2 is a block diagram showing a hardware configuration of the vehicle display device 10. As shown in FIG.

[0018] 2, the vehicle display device 10 includes a CPU (Central Processing Unit) 30, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 34, a storage 36, a GPS receiver 38, a user interface 40, the display device 16, and a communication interface 42. Each component is connected to each other via a bus 44 so as to be able to communicate with each other.

[0019] The CPU 30 is a central processing unit, and executes various programs and controls each part. That is, the CPU 30 reads a program from the ROM 32 or the storage 36, and executes the program using the RAM 34 as a working area. The CPU 30 controls each of the above components and performs various arithmetic processing according to the program recorded in the ROM 32 or the storage 36. In this embodiment, the ROM 32 or the storage 36 stores an information display program for switching the size of the display range of information displayed on the display device 16 when switching the driving mode (automatic driving or manual driving) of the vehicle 12.

[0020] The ROM 32 stores various programs and various data. The RAM 34 temporarily stores programs or data as a working area. The storage 36 is configured with an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs including an operating system and various data.

[0021] The GPS receiver 38 receives signals based on the GPS system from a plurality of satellites, and identifies the position of the vehicle 12 (vehicle display device 10) from the arrival time difference of the signals.

[0022] The user interface 40 is an interface used when the driver or other passengers in the vehicle 12 use the vehicle display device 10. As an example, the user interface 40 includes at least one of a liquid crystal display equipped with a touch panel that allows the driver to perform touch operations, a voice input unit that accepts voice input by the driver, and a button that the driver can press.

[0023] The display device 16 displays information to a driver who is driving the vehicle 12. The display device 16 is a head-up display (hereinafter referred to as "HUD") provided inside the instrument panel, and displays information on the windshield (both not shown) by projecting information onto the windshield through an opening (not shown) in the instrument panel.

[0024] The display contents projected by the HUD onto the windshield can be displayed superimposed on the scenery of the real space in front of the vehicle. In other words, the display contents projected onto the windshield can be visually recognized by the driver. Examples of information projected by the HUD include the vehicle's traveling speed, a navigation screen to the destination, weather information, etc. The HUD can display information on a part of the windshield or on almost the entire windshield by adjusting the angle and focus of a reflector, lens, etc. (not shown) provided inside the HUD.

[0025] Furthermore, the display device 16 is provided with a camera (not shown) that captures an image of the driver's face, and the CPU 30 can detect the driver's line of sight direction based on the image captured by this camera.

[0026] The communication interface 42 is an interface for communicating with the external server 24 (see FIG. 1), and uses standards such as Ethernet (registered trademark), FDDI, and Wi-Fi (registered trademark).

[0027] (Functional configuration) When executing the above information display program, the vehicle display device 10 uses the above hardware resources to realize various functions. The functional configuration realized by the vehicle display device 10 will be described.

[0028] FIG. 3 is a block diagram showing an example of a functional configuration of the vehicle display device 10. As shown in FIG.

[0029] 3, the vehicle display device 10 has, as functional components, a determination unit 20, a display control unit 22, and a display unit 23. Each functional component is realized by the CPU 30 reading and executing an information display program stored in the ROM 32 or the storage 36 (see FIG. 2).

[0030] The determination unit 20 receives information about the driving situation from the driving control unit 18 (see FIG. 1). From the information about the driving situation, the determination unit 20 determines the driving mode, whether the vehicle is currently in manual driving or automatic driving. The determination unit 20 also determines whether a driving mode switch, i.e., a switch from automatic driving to manual driving or a switch from manual driving to automatic driving, will occur in the near future.

[0031] In addition, the determination unit 20 is connected to the steering wheel and accelerator or brake (none of which are shown) inside the vehicle cabin via an in-vehicle network not shown, and determines whether or not the driving mode switching has been completed based on whether or not the steering wheel, accelerator or brake of the vehicle 12 has been operated.

[0032] The display control unit 22 determines the size of information displayed by the display device 16 (see FIG. 1) according to the driving mode determined by the determination unit 20. That is, when the vehicle 12 is being manually driven, the display control unit 22 displays the information small on a portion of the windshield that corresponds to the driver's front side of the vehicle. At this time, the display control unit 22 displays the information at a position that corresponds to the detected line of sight of the driver. On the other hand, when the vehicle 12 is being automatically driven, the display control unit 22 displays the information large over substantially the entire surface of the windshield. Note that, in this embodiment, the size of the information display refers to the amount of information to be displayed, but is not limited thereto, and may refer to a change in the size of the information display itself or other sizes.

[0033] The display unit 23 displays the information according to the size of the information display determined by the display control unit 22. The display unit 23 displays the information on the windshield toward the driver in the vehicle cabin.

[0034] (Processing flow) Next, a description will be given of the operation of the vehicle display device 10. Fig. 4 is a flowchart showing the flow of the operation of the vehicle display device 10. The CPU 30 reads out an information display program from the ROM 32 or the storage 36, expands it in the RAM 34, and executes it, thereby switching the information display corresponding to the driving mode.

[0035] The CPU 30 analyzes the information on the driving situation received from the driving control unit 18, and determines whether the vehicle 12 is currently in an autonomous driving state (step S100).

[0036] If the vehicle 12 is in automatic driving (step S100: YES), the CPU 30 displays the information in a large size covering almost the entire area of ​​the windshield, and determines whether or not switching from automatic driving to manual driving will occur in the near future based on the information received from the driving control unit 18 (step S102). If switching from automatic driving to manual driving will not occur in the near future (step S102: NO), the CPU 30 repeats step S102. If switching from automatic driving to manual driving will occur in the near future (step S102: YES), the CPU 30 determines whether or not switching to manual driving has been completed (step S104). If switching to manual driving has not been completed (step S104: NO), the CPU 30 repeats step S104. If switching to manual driving has been completed (step S104: YES), the CPU 30 reduces the display of information on the display device 16 (step S106). Thereafter, the CPU 30 moves the information displayed on the display device 16 in the direction of the driver's line of sight (step S108), and ends the process.

[0037] On the other hand, when the vehicle 12 is not in automatic driving, that is, when the vehicle 12 is in manual driving (step S100: NO), the CPU 30 displays the information in a small size on a part of the windshield and determines whether or not switching from manual driving to automatic driving will occur in the near future based on the information received from the driving control unit 18 (step S110). When switching from manual driving to automatic driving will not occur in the near future (step S110: NO), the CPU 30 repeats step S110. When switching from manual driving to automatic driving will occur in the near future (step S110: YES), the CPU 30 determines whether or not switching to automatic driving has been completed (step S112). When switching to automatic driving has not been completed (step S112: NO), the CPU 30 repeats step S112. When switching to automatic driving has been completed (step S112: YES), the CPU 30 enlarges the display of the information on the display device 16 (step S114), and then ends the process.

[0038] (Actions and Effects of the First Embodiment) Next, the operation and effects of the first embodiment will be described.

[0039] In this embodiment, as shown in FIG. 3, the vehicle display device 10 has a determination unit 20, a display unit 23, and a display control unit 22. The determination unit 20 determines the operating state of the driving control unit 18 that switches between automatic driving and manual driving of the vehicle 12 capable of automatic driving. Therefore, it can be determined whether the vehicle 12 is in automatic driving or manual driving. The display unit 23 is provided in the vehicle cabin of the vehicle 12 and displays information on the windshield toward the vehicle cabin. When the determination unit 20 determines that the vehicle 12 is in automatic driving, the display control unit 22 enlarges the information displayed by the display unit 23 onto the windshield. In addition, when the determination unit 20 determines that the vehicle 12 switches from automatic driving to manual driving, the display control unit 22 reduces the display by the display unit 23 on the windshield. Therefore, during automatic driving, the information is displayed enlarged on the windshield, and the driver's view outside the vehicle is blocked over a wide area. In other words, even if the driver changes his / her posture during autonomous driving, the driver is freed from having to monitor the traffic conditions around the vehicle because the view to the front of the vehicle is blocked. This allows the driver to feel more free from driving in an autonomous vehicle.

[0040] Second embodiment Next, a vehicle display device according to a second embodiment of the present invention will be described with reference to Fig. 5. Note that the same components as those in the first embodiment described above are given the same reference numerals and the description thereof will be omitted.

[0041] A vehicle display device 60 (see FIG. 1) according to the second embodiment has the same basic configuration as the first embodiment, and is characterized in that the information displayed by the display device 16 is gradually switched.

[0042] (Functional configuration) That is, the display control unit 62 (see FIG. 3) in the vehicle display device 60 switches the size of information displayed by the display device 16 (see FIG. 1) depending on the driving mode determined by the determination unit 20. Specifically, when the vehicle 12 is being manually driven, the display control unit 62 displays the information small on a portion of the windshield that corresponds to the vehicle front side of the driver. On the other hand, when the vehicle 12 is being automatically driven, the display control unit 62 displays the information over substantially the entire surface of the windshield. Furthermore, when the driving mode will be switched from automatic to manual driving in the near future, the display control unit 62 gradually reduces the information displayed over substantially the entire surface of the windshield, and then displays the information at a position corresponding to the detected line of sight of the driver.

[0043] (Processing flow) Next, the operation of the vehicle display device 60 (see FIG. 1) will be described. FIG. 5 is a flowchart showing the flow of the operation of the vehicle display device 60. The CPU 30 reads out an information display program from the ROM 32 or the storage 36, expands it in the RAM 34, and executes it, thereby switching the information display corresponding to the driving mode.

[0044] When the changeover to manual driving is completed in step S102, the CPU 30 gradually reduces the display of information on the display device 16 (step S130). After that, the CPU 30 moves the information displayed on the display device 16 toward the line of sight of the driver (step S108) and ends the process.

[0045] (Actions and Effects of the Second Embodiment) Next, the operation and effects of the second embodiment will be described.

[0046] The above configuration is also similar to the vehicular display device 10 of the first embodiment except that the information displayed by the display device 16 is gradually switched, and therefore the same effects as those of the first embodiment can be obtained. Furthermore, the vehicular display device 60 allows the driver to intuitively understand that the driving mode is switching from automatic to manual driving by gradually switching (reducing) the information displayed by the display device 16 when switching from automatic to manual driving.

[0047] In the above embodiment, the information displayed by the display device 16 is gradually reduced when switching from automatic driving to manual driving, but the present invention is not limited to this, and the information displayed by the display device 16 may be gradually enlarged when switching from manual driving to automatic driving. This allows the driver to smoothly understand that the driving mode has been switched to automatic driving.

[0048] Third embodiment Next, a vehicle display device according to a third embodiment of the present invention will be described with reference to Fig. 6. Note that the same components as those in the first embodiment and the like are designated by the same reference numerals and the description thereof will be omitted.

[0049] A vehicle display device 70 (see FIG. 1) according to the third embodiment has the same basic configuration as the first embodiment, and is characterized in that the display of information is controlled based on current location information.

[0050] (Functional configuration) That is, as shown in Fig. 3, the display control unit 72 switches the size of information displayed by the display device 16 (see Fig. 1) depending on the driving mode determined by the determination unit 20. Specifically, when the vehicle 12 is being manually driven, the display control unit 72 displays the information small on a portion of the windshield that corresponds to the driver's front side of the vehicle. At this time, the display control unit 72 displays the information at a position that corresponds to the detected line of sight of the driver. On the other hand, when the vehicle 12 is being automatically driven, the display control unit 72 displays the information over substantially the entire area of ​​the windshield.

[0051] In addition, the display control unit 72 acquires current location information from the GPS receiver 38 (see FIG. 2), and when the current location corresponds to a scenic spot or a location nearby that is registered in advance in the storage 36 (see FIG. 2) or the external server 24 (see FIG. 1), it reduces the information that was displayed over almost the entire surface of the windshield and displays it in a smaller size.

[0052] (Processing flow) Next, a description will be given of the operation of the vehicle display device 70. Fig. 6 is a flowchart showing the flow of the operation of the vehicle display device 70. The CPU 30 reads out an information display program from the ROM 32 or the storage 36, deploys it in the RAM 34, and executes it, thereby switching the information display corresponding to the driving mode.

[0053] The CPU 30 analyzes the information on the driving situation received from the driving control unit 18 (see FIG. 1), and determines whether the vehicle 12 is currently in an autonomous driving state (step S160).

[0054] If the vehicle 12 is not autonomously driven (step S160: NO), the CPU 30 ends the process. If the vehicle 12 is autonomously driven (step S160: YES), the CPU 30 acquires current location information from the GPS receiver 38 (see FIG. 2) (step S162).

[0055] Based on the acquired current location information, the CPU 30 determines whether the current location corresponds to a scenic spot or is near a scenic spot registered in advance (step S164). If the current location does not correspond to a scenic spot or is near a scenic spot (step S164: NO), the CPU 30 repeats the process from step S160. If the current location corresponds to a scenic spot or is near a scenic spot (step S164: YES), the CPU 30 gradually reduces the display of information on the display device 16 (step S166). After that, the CPU 30 moves the information displayed on the display device 16 toward the driver's line of sight (step S168).

[0056] The CPU 30 again acquires current location information by the GPS receiver 38 (see FIG. 2) (step S170). Based on the acquired current location information, the CPU 30 determines whether the current location has passed or passed near a scenic spot or a preregistered scenic spot (step S172). If the current location has not left the scenic spot or near a scenic spot or a preregistered scenic spot (the current location corresponds to a scenic spot or near a scenic spot) (step S172: NO), the CPU 30 repeats the process from step S170. If the current location has left the scenic spot or near a scenic spot or a preregistered scenic spot (step S172: YES), the CPU 30 enlarges the display of information on the display device 16 (step S174), and then ends the process.

[0057] (Actions and Effects of the Third Embodiment) Next, the operation and effects of the third embodiment will be described.

[0058] The above configuration is similar to the vehicular display device 10 of the first embodiment except that the display of information is controlled based on current location information, and therefore the same effects as those of the first embodiment can be obtained. The vehicular display device 70 also controls the display of information based on current location information. Specifically, when information is displayed on almost the entire windshield during autonomous driving, if the vehicle 12 travels through or near a scenic spot, the information displayed on the windshield is reduced in size. Therefore, the driver can view scenic spots while driving even during autonomous driving, and the vehicular display device 70 can provide the occupants with an enjoyable travel time.

[0059] (Fourth embodiment) Next, a vehicle display device according to a fourth embodiment of the present invention will be described with reference to Fig. 7. Note that the same components as those in the first embodiment and the like are designated by the same reference numerals and the description thereof will be omitted.

[0060] A vehicle display device 80 (see FIG. 1) according to the fourth embodiment has the same basic configuration as the first embodiment, and is characterized in that the display of information can be controlled by the driver's operation.

[0061] (Functional configuration) That is, as shown in Fig. 3, the display control unit 82 switches the size of information displayed by the display device 16 (see Fig. 1) depending on the driving mode determined by the determination unit 20. Specifically, when the vehicle 12 is being manually driven, the display control unit 82 displays the information small on a portion of the windshield that corresponds to the driver's front side of the vehicle. At this time, the display control unit 82 displays the information at a position that corresponds to the detected line of sight of the driver. On the other hand, when the vehicle 12 is being automatically driven, the display control unit 82 displays the information over substantially the entire area of ​​the windshield.

[0062] In addition, when the display control unit 82 receives an instruction from the driver via the user interface 40 (see Figure 2) during autonomous driving that the driver wants to see the scenery outside, the display control unit 82 reduces the information that was displayed over almost the entire surface of the windshield and displays it in a smaller size.

[0063] (Processing flow) Next, a description will be given of the operation of the vehicle display device 80. Fig. 7 is a flowchart showing the flow of the operation of the vehicle display device 80. The CPU 30 reads out an information display program from the ROM 32 or the storage 36, deploys it in the RAM 34, and executes it, thereby switching the information display corresponding to the driving mode.

[0064] The CPU 30 analyzes information relating to the driving situation received from the driving control unit 18 (see FIG. 1), and determines whether the vehicle 12 is currently in an autonomous driving state (step S200).

[0065] If the vehicle 12 is not in autonomous driving mode (step S200: NO), the CPU 30 ends the process. If the vehicle 12 is in autonomous driving mode (step S200: YES), the CPU 30 determines whether or not an instruction to view the outside scenery has been received from the driver via a button or the like (not shown) on the user interface 40 (step S202). If an instruction to view the outside scenery has not been received from the driver (step S202: NO), the CPU 30 repeats the process of step S202. If an instruction to view the outside scenery has been received from the driver (step S202: YES), the CPU 30 reduces the display of information on the display device 16 (step S204). Then, the process ends.

[0066] (Actions and Effects of the Fourth Embodiment) Next, the operation and effects of the fourth embodiment will be described.

[0067] The above configuration is also similar to the vehicular display device 10 of the first embodiment, except that the display of information can be controlled by the driver's operation, and therefore the same effects as those of the first embodiment can be obtained. In addition, since the vehicular display device 80 is capable of controlling the display of information by the driver's operation, when the driver wants to know the outside situation due to a traffic jam or an accident during automatic driving, the information displayed on the windshield can be reduced by operating the user interface 40, making it easier to see outside. This allows the driver to see the situation around the vehicle if he or she wishes, even during automatic driving.

[0068] In the above-described embodiment, the CPU 30 terminates the processing after reducing the display of the information on the display device 16, but this is not limited thereto. The display of the information may be enlarged again after a certain period of time has elapsed, or the driver may enlarge the display of the information by operating the user interface 40 again.

[0069] In the first to fourth embodiments, the vehicle display device 10, 60, 70, 80 is configured to display information using a HUD, but the present invention is not limited to this, and may be configured to display information using a display device such as a liquid crystal screen built into or attached to the windshield, or may be configured to display information using other display devices. Furthermore, the vehicle display device 10, 60, 70, 80 displays information on the windshield, but the present invention is not limited to this, and may be configured to display information on other glass such as a side window glass or a rear window glass.

[0070] Furthermore, the vehicle display device 10, 60, 70, 80 determines the size of the information displayed by the display device 16 (see FIG. 1) in accordance with the driving mode determined by the determination unit 20, but this is not limited to the above, and the size of the information displayed by the display device 16 (see FIG. 1) may be determined (switched) by receiving a command from an external server 24, center, etc.

[0071] In addition, the display control units 22, 62, 72, 82 display information large and across almost the entire surface of the windshield when the vehicle 12 is in autonomous driving mode, but this is not limited to the above, and the information does not need to be displayed across almost the entire surface as long as it blocks the driver's view outside the vehicle to some extent.

[0072] Although an embodiment of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement the present invention in various other modified forms without departing from the spirit and scope of the present invention.
