Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when a four-wheel drive vehicle is in autonomous driving, since the driver does not operate it himself / herself, there is a high possibility that displays other than the driving force distribution display are desired. Therefore, a technique for appropriately displaying the display of the display device according to each driving mode of manual driving and autonomous driving has been demanded.

Means for Solving the Problems

[0005] The present disclosure can be realized in the following forms. 3] (1) According to one embodiment of the present disclosure, a display control device is provided for a vehicle. In this display control device, the vehicle has an automatic driving mode or a manual driving mode as a driving mode, and is equipped with a display unit that displays information to the occupant, and the display control device controls the display unit and is equipped with a plurality of display modes, the plurality of display modes including a first type of display mode that displays the status of the vehicle at the time of display, and a second type of display mode that does not display the status of the vehicle at the time of display, and when a predetermined first condition is met, including the driving mode being switched from the manual driving mode in which the first type of display mode was being displayed on the display unit to the automatic driving mode, and no instruction has been given to display a display mode other than the second type of display mode, the display unit displays the second type of display mode at the time of display in the automatic driving mode.

[0006] (1) According to one embodiment of the present disclosure, a display control device provided for a vehicle. In this display control device, the vehicle has an automatic driving mode or a manual driving mode as a driving mode, and is equipped with a display unit that displays information to the occupant. The display control device controls the display unit and is equipped with a plurality of display modes, the plurality of display modes including a first type of display mode that displays the status of the vehicle at the time of display, and a second type of display mode that does not display the status of the vehicle at the time of display. When a predetermined first condition is met, including the driving mode being switched from the manual driving mode in which the first type of display mode was being displayed on the display unit to the automatic driving mode, the display control device displays the second type of display mode on the display unit at the time of display in the automatic driving mode. By adopting this configuration, the display control device of this disclosure displays in Type 2 display mode at the time of display in automatic driving mode. In automatic driving mode, the likelihood of the occupant being involved in driving is low, so the likelihood of the occupant wanting to see Type 1 display mode, which displays the vehicle's status at the time of display, is low. Therefore, the display control device of this disclosure increases the likelihood of being able to display the display mode desired by the occupant on the display unit, depending on the driving mode. (2) In the above-described display control device, the second type of display mode may also be a mode that displays statistical data on the vehicle's condition prior to the time of display. By adopting this configuration, the display control device of the present disclosure displays data in the second type of display mode at the time of display in the automated driving mode. Passengers who are not driving are more likely to want statistical data representing the vehicle's condition at the time of display in order to know the appropriateness of the driving performance under automated driving, rather than the vehicle's condition at the time of display. For example, these statistical data may include average fuel consumption or average vehicle speed. Therefore, the display control device of the present disclosure can determine the appropriateness of the driving performance under automated driving. (3) In the above-described display control device, the vehicle further comprises a plurality of drive wheels to which driving force is transmitted, and a driving force adjustment device for adjusting the driving force of each of the plurality of drive wheels. The first type of display mode may also include a driving force distribution display mode that shows the driving force of each of the plurality of drive wheels. In this configuration, even when the display control device of the present disclosure has a driving force distribution display mode as the first type of display mode, it can display a second type of display mode desired by the driver in automatic driving mode. (4) In the above-described display control device, the display control device may further store information on the frequency with which each of the second type of display modes has been displayed during a predetermined first period, and when the first condition is met, it may display the display mode of the second type of display modes that has been displayed most frequently, based on the frequency information. In this configuration, the display control device of the present disclosure can display on the display unit the display mode that is most likely to be desired by the passenger, based on the frequency with which the display modes have been displayed. (5) In the above-described display control device, the display control device may further store information on the time each of the second type of display modes was displayed during a predetermined first period, and when the first condition is met, it may display the display mode among the second type of display modes that has been displayed for the longest time based on the time information. In this configuration, the display control device of the present disclosure can display on the display unit the display mode that is most likely to be desired by the passenger, based on the time the display mode has been displayed.

[0008] A. First Embodiment: A-1. Configuration of the first embodiment: Figure 1 is an explanatory diagram showing the configuration of the first embodiment. The display control device 600 is installed in the vehicle 1000. When the vehicle 1000 has an occupant, it has an automatic driving mode or a manual driving mode as a driving mode. The driving modes will be described in detail later. Furthermore, the vehicle 1000 is a four-wheel drive vehicle. In the following description, the configuration of the vehicle 1000 will be described before describing the display control device 600. The vehicle 1000 comprises a plurality of drive wheels 100, a driving execution unit 200, an information acquisition unit 300, a vehicle control device 400, and a display unit 500.

[0009] The multiple drive wheels 100 transmit the driving force necessary for the vehicle 1000 to travel to the road surface. In other words, the multiple drive wheels 100 are the wheels to which the driving force output by the drive unit 210 is transmitted. The multiple drive wheels 100 consist of a pair of front wheels 110R and 110L, which are arranged on the left and right sides of the vehicle 1000, and a pair of rear wheels 120R and 120L, which are also arranged on the left and right sides of the vehicle 1000. The multiple drive wheels 100 are connected to the driving execution unit 200 via axles and propeller shafts. In Figure 1, structural details have been omitted to facilitate understanding of the technology.

[0010] The driving execution unit 200 executes the operation of the vehicle 1000. The driving execution unit 200 comprises a drive unit 210, a braking unit 220, and a steering unit 230. The driving execution unit 200 is connected to the vehicle control device 400 via a communication line. The driving execution unit 200 executes the operation of the vehicle 1000 using the drive unit 210, the braking unit 220, and the steering unit 230 in response to commands from the vehicle control device 400.

[0011] The drive unit 210 drives the vehicle 1000. The drive unit 210 consists of, for example, an engine, a transmission, and a drive force adjustment device. In Figure 1, for the sake of ease of understanding the technology, the drive unit 210 other than the drive force adjustment device is omitted from the illustration.

[0012] The drive force adjustment device adjusts the driving force of each of the multiple drive wheels 100. The drive force adjustment device is composed of, for example, an electromagnetic clutch 211 and a drive force adjustment unit 411. The drive force adjustment device is installed between the front and rear drive wheels 100, between the front wheel 110R and the front wheel 110L, and between the rear wheel 120R and the rear wheel 120L, thereby adjusting the driving force of each of the multiple drive wheels 100. The drive force adjustment unit 411 is a functional part of the processor 410 in the vehicle control device 400, which will be described later. That is, the drive force adjustment unit 411 adjusts the driving force of each of the multiple drive wheels 100 by controlling the electromagnetic clutch 211. Information on the amount of driving force distributed to each of the multiple drive wheels 100 is sent to the display control device 600. The amount of driving force distribution will be described in detail later.

[0013] The braking system 220 performs braking on the vehicle 1000. For example, the braking system 220 is configured as an electronically controlled braking system.

[0014] The steering device 230 performs the steering of the vehicle 1000. For example, it is configured as an electric power steering system.

[0015] The information acquisition unit 300 acquires information inside or outside the vehicle 1000. For example, the information acquisition unit 300 is various sensors provided in the vehicle 1000 such as an image sensor, a radar sensor, and a yaw rate sensor. Further, the information acquisition unit 300 is a navigation device or an audio device that acquires information through a communication line or a storage medium. The information acquisition unit 300 is connected to the display control device 600 and the vehicle control device 400. The information acquired by the information acquisition unit 300 is sent to the display control device 600 and the vehicle control device 400 through a communication line. Note that the information acquisition unit 300 sends information only to the display control device 600 for information not related to the control of the vehicle 1000.

[0016] The vehicle control device 400 controls the vehicle 1000. The vehicle control device 400 includes a processor 410, a ROM 420, and a RAM 430. The ROM 420 is a read-only semiconductor memory and stores a control program for controlling the vehicle 1000 in advance. The RAM 430 is a readable and writable semiconductor memory, and the RAM 430 stores information necessary for controlling the vehicle 1000. The processor 410 realizes various functions by loading the control program stored in the ROM 420 into the RAM 430 and executing it. The vehicle control device 400 is connected to the display control device 600, the driving execution unit 200, and the information acquisition unit 300 through a communication line.

[0017] More specifically, the vehicle control device 400 controls the driving execution unit 200 according to the automatic driving mode and the manual driving mode as driving modes.

[0018] In the manual driving mode, the vehicle control device 400 controls the vehicle 1000 according to the manual driving by the driver. More specifically, the vehicle control device 400 controls the vehicle 1000 by controlling various driving devices 210 according to the operations of the accelerator, brake, and steering wheel H by the driver.

[0019] In autonomous driving mode, the vehicle control device 400 controls the autonomous driving of the vehicle 1000. More specifically, the vehicle control device 400 controls the driving execution unit 200 using detection results from sensors in the information acquisition unit 300 and map information from the navigation device.

[0020] In this embodiment, the vehicle 1000 has passengers in the automatic driving mode. However, in this embodiment, the vehicle control device 400 is the primary driver. Therefore, for example, a state in which both the operation of the accelerator and brake and the operation of the steering wheel H are partially automated is the manual driving mode in this embodiment.

[0021] Furthermore, the vehicle control device 400 sends information about the status of the vehicle 1000 to the display control device 600. The status of the vehicle 1000 includes, for example, the driving conditions and external conditions. More specifically, the driving conditions include the amount of driving force distribution, which will be explained later, and the magnitude of acceleration and deceleration of the vehicle 1000. External conditions include signs and obstacles present around the vehicle 1000, which are acquired by the information acquisition unit 300. Furthermore, external conditions also include traffic congestion and route information received by the navigation device.

[0022] Figure 2 is an explanatory diagram showing the display unit 500. The display unit 500 displays information to the passenger. More specifically, the display unit 500 displays several types of display modes, which will be described later, under the control of the display control device 600. The display unit 500 is, for example, a liquid crystal display. The display unit 500 is positioned, for example, in front of the driver's seat, below where the speedometer M is located, as shown in Figure 2. The display unit 500 is connected to the display control device 600.

[0023] Next, the display control device 600 shown in Figure 1 will be described. The display control device 600 controls the display unit 500. The display control device 600 has multiple display modes to display on the display unit 500. The display control device 600 displays one of the multiple display modes on the display unit 500. The display control device 600 consists of a processor 610, a ROM 620, and a RAM 630. The configurations of each component are the same as those of the processor 410, ROM 420, and RAM 430 in the vehicle control device 400. The functions of the display control device 600 will be described in detail later.

[0024] A-2. Multiple display modes: The display control device 600 includes multiple display modes, including a first display mode M10, a second display mode M20, and a third display mode.

[0025] The first display mode M10 displays the status of the vehicle 1000 at the time of display by the display unit 500. More specifically, the status of the vehicle 1000 at the time of display is the latest status of the vehicle 1000 that can be displayed at the time of display. Therefore, the first display mode M10 displays the status of the vehicle 1000 in real time. The display control device 600 has multiple display modes as the first display mode M10. For example, the first display mode M10 includes a drive force distribution display mode M11 and an eco-drive indicator display mode M12.

[0026] Figure 3 is an explanatory diagram showing the drive force distribution display mode M11. The drive force distribution display mode M11 shows the drive force of each of the multiple drive wheels 100. More specifically, the drive force distribution display mode M11 displays the amount of drive force distributed to each of the front and rear drive wheels 100. As shown in Figure 3, the drive force distribution display mode M11 displays a schematic diagram representing the multiple drive wheels 100. Furthermore, the drive force distribution display mode M11 displays scales M11a to M11d corresponding to the amount of drive force distributed to the front wheels 110R and 110L as a pair of wheels, and to the rear wheels 120R and 120L as a pair of wheels. The increase or decrease in the color scheme of each scale indicates the increase or decrease in the amount of drive force distributed.

[0027] The drive force distribution display mode M11 represents the amount of drive force distributed at the time of display by the display unit 500. In other words, the drive force distribution display mode M11 changes each scale in real time in response to changes in the amount of drive force distributed.

[0028] Figure 4 is an explanatory diagram showing the Eco-Drive Indicator display mode M12. The Eco-Drive Indicator display mode M12 shows the evaluation results of environmentally conscious driving methods. As shown in Figure 4, the Eco-Drive Indicator display mode M12 has three ranges. The Eco-Drive Indicator display mode M12 shows the evaluation results of environmentally conscious driving by lighting up in each range. More specifically, lighting up in range M12a indicates the accelerator opening at the time of display. Range M12b is the range of accelerator openings that are evaluated as environmentally conscious driving. Range M12c is the range of accelerator openings that exceeds range M12b.

[0029] The power distribution display mode M11 and the eco-drive indicator display mode M12 inform the driver of the vehicle's status in real time. Therefore, the driver can review their driving method in real time.

[0030] The second display mode M20 does not display the status of vehicle 1000 at the time of display. More specifically, the second display mode M20 displays statistical data on the status of vehicle 1000 prior to the time of display. Below, the average fuel consumption display mode M21 and the average vehicle speed display mode M22 are given as examples of display modes in the second display mode M20.

[0031] Figure 5 is an explanatory diagram showing the average fuel consumption display mode M21. The average fuel consumption display mode M21 displays the average fuel consumption of vehicle 1000 over a predetermined measurement period. The predetermined measurement period is, for example, the period from the time the switch is turned on by the occupant by providing a switch on the display unit 500 until the present. This measurement period is also called the reset period. In Figure 5, the average fuel consumption of vehicle 1000 over the measurement period is illustrated as "average fuel consumption over the reset period".

[0032] Figure 6 is an explanatory diagram showing the average vehicle speed display mode M22. The average vehicle speed display mode M22 displays the average vehicle speed of 1000 vehicles during the measurement period. The predetermined measurement period is the same as the measurement period in the average fuel consumption display mode M21.

[0033] The average fuel consumption display mode M21 and the average vehicle speed display mode M22 provide the occupant with statistical data indicating the status of vehicle 1000. By reviewing these statistics, the occupant can, for example, comprehensively evaluate the vehicle 1000's performance up to the displayed point in time.

[0034] The third display mode displays content that is not related to the status of the vehicle 1000. For example, the third display mode includes videos and images acquired by the information acquisition unit 300 via a communication line.

[0035] A-3. Processing of the display control device: Figure 7 is a flowchart showing the display processing in the first embodiment. The functions of the display control device 600 are described below. The display control device 600 starts processing in response to the switching of the driving mode by the vehicle control device 400.

[0036] In step S110 of Figure 7, the display control device 600 checks the driving mode. More specifically, if the driving mode is automatic driving mode, the display control device 600 proceeds to step S120. If the driving mode is manual driving mode, the display control device 600 proceeds to step S111.

[0037] In step S111 of Figure 7, the display control device 600 maintains the display mode at the time of display on the display unit 500. That is, the display control device 600 does not switch the display mode. After the processing in step S111, the display control device 600 terminates the processing of this flowchart.

[0038] In step S120 of Figure 7, the display control device 600 checks the display mode at the time of display on the display unit 500 in automatic driving mode. More specifically, if the display mode at the time of display on the display unit 500 is the first type display mode M10, the display control device 600 proceeds to step S130. If the display mode at the time of display on the display unit 500 is the second type display mode M20, the display control device 600 proceeds to step S111.

[0039] As a result of the processing in steps S130 to S140 in Figure 7, the display control device 600 displays in the display unit 500 using the second display mode M20. More specifically, the display control device 600 displays in the second display mode M20 when a predetermined first condition is met, including the fact that the driving mode has been switched from manual driving mode, in which the first display mode M10 was being displayed, to automatic driving mode. This process will be explained in detail below.

[0040] In step S130 of Figure 7, the display control device 600 checks the first condition. The first condition includes the condition that the driving mode has been switched to the automatic driving mode. The condition that the driving mode has been switched to the automatic driving mode is called the driving mode condition. In step S130, the driving mode condition is met. In addition to the driving mode condition, the first condition also includes conditions related to other display modes. Conditions related to other display modes include, for example, the condition that no instruction has been given to display in the first display mode M10 even in the automatic driving mode, or the condition that no instruction has been given to display the third display mode, such as a video distributed via a communication line, in the automatic driving mode. In other words, the condition related to other display modes is the condition that no instruction has been given to display a display mode other than the second display mode. Therefore, if the first condition is not met, the display control device 600 proceeds to step S131. If the first condition is met, the display control device 600 proceeds to step S140.

[0041] In step S131 of Figure 7, the display control device 600 displays a different display mode based on an instruction to display a display mode other than the second type display mode. For example, if an instruction is given to display the first type display mode M10 even in automatic driving mode, the display control device 600 displays the first type display mode M10.

[0042] In step S140 of Figure 7, the display control device 600 displays the second type of display mode M20 on the display unit 500. If the second type of display mode M20 includes multiple display modes, the display control device 600 displays, for example, the display mode that has been displayed most frequently. This frequency is the frequency with which each display mode of the second type of display mode M20 has been displayed during a predetermined first period. The first period is the period during which automatic operation has been performed, which is included within a predetermined time from the present moment. For example, the first period is the period from the time of display to one month prior. The frequency information is stored in the RAM 630 of the display control device 600. Therefore, if the first condition is met, the display control device 600 displays the second type of display mode M20 that has been displayed most frequently, based on the frequency information of the modes displayed during the first period. After the processing in step S140, the display control device 600 terminates the processing of this flowchart.

[0043] By adopting this configuration, the display control device 600 of this disclosure displays in the second display mode M20 at the time of display in the automatic driving mode. In the automatic driving mode, the likelihood of the passenger being involved in driving is low, so the likelihood of the passenger wanting the first display mode M10, which displays the status of the vehicle at the time of display, is low. Therefore, the display control device 600 of this disclosure increases the likelihood of being able to display the display mode desired by the passenger on the display unit 500, depending on the driving mode.

[0044] Furthermore, the display control device 600 of this disclosure displays information in the second display mode M20 at the time of display in the automatic driving mode. Passengers who are not driving are more likely to want statistics representing the status of the vehicle 1000 at the time of display in order to know the appropriateness of the driving performance under automatic driving, rather than the status of the vehicle 1000 at the time of display. For example, these statistics may be average fuel consumption or average vehicle speed. Therefore, the display control device 600 of this disclosure can know the appropriateness of the driving performance under automatic driving.

[0045] Furthermore, even when the display control device 600 of this disclosure has a driving force distribution display mode M11 as a first type display mode M10, in automatic driving mode it can display a second type display mode M20 desired by the driver.

[0046] Furthermore, the display control device 600 of this disclosure can display on the display unit 500 the display mode that is most likely to be desired by the passenger, based on the frequency with which the display mode has been displayed.

[0047] B. Second Embodiment: In the first embodiment, the display control device 600 displays the display mode that is most frequently displayed among the second type display modes M20 as the process in step S140 of Figure 7. However, if the first condition is met, the display control device 600 may display the display mode that has been displayed for the longest time among the second type display modes M20 based on time information. This time is the time that each display mode of the second type display modes M20 has been displayed in a predetermined first period. The first period is the same as the first period in the first embodiment.

[0048] By adopting this configuration, the display control device 600 of the second embodiment can display on the display unit 500 the display mode that is most likely to be desired by the passenger, based on the time the display mode has been displayed.

[0049] C. Third Embodiment: In the above embodiment, the first display mode M10 displays the status of the vehicle 1000 at the time of display, and the second display mode M20 displays statistical data on the status of the vehicle 1000 prior to the time of display. The display control device 600 in the third embodiment may further include a fourth display mode that displays both the status of the vehicle 1000 at the time of display and statistical data on the status of the vehicle 1000 prior to the time of display. For example, the fourth display mode causes the display unit 500 to display the evaluation results in the eco-drive indicator display mode M12 and the average fuel consumption in the average fuel consumption display mode M21.

[0050] The display control device 600 of the third embodiment treats the fourth type of display mode as either the first type of display mode M10 or the second type of display mode M20, based on the size of the area displaying the information of the status of the vehicle 1000 at the time of display and the statistical amount of the status of the vehicle 1000 prior to the time of display. That is, in the process shown in Figure 7, the fourth type of display mode is treated as the first type of display mode M10 when the information representing the status of the vehicle 1000 at the time of display is displayed in the largest size. Furthermore, the fourth type of display mode is treated as the second type of display mode M20 when the information representing the statistical amount of the status of the vehicle 1000 prior to the time of display is displayed in the largest size.

[0051] By adopting this configuration, even if the display control device 600 of the third embodiment includes a fourth type of display mode that displays the status of the vehicle 1000 at the time of display and statistical data on the status of the vehicle 1000 prior to the time of display, the display unit 500 can display the display mode that is most likely to be desired by the passenger.

[0052] D. Other embodiments: (1) In the above embodiment, the display control device 600 includes, for example, a drive force distribution display mode M11 and an eco-drive indicator display mode M12 as the first type display mode M10. However, the display control device 600 only needs to include one or more display modes as the first type display mode M10. That is, the display control device 600 may have only a drive force distribution display mode M11 as one first type display mode M10. Similarly, with respect to the second type display mode M20, the display control device 600 only needs to have one or more display modes as the second type display mode M20. That is, the display control device 600 may have only an average fuel consumption display mode M21 as one second type display mode M20. (2) In the above embodiment, the second display mode M20 displays statistical data on the vehicle's condition prior to the time of display. The second display mode M20 does not need to display the condition of vehicle 1000 at the time of display. For example, the second display mode M20 may display the condition of vehicle 1000 during a period that does not include the time of display. More specifically, it may display statistical data on the condition of vehicle 1000 during a predetermined period prior to the time of display. Furthermore, for example, the second display mode M20 may display predicted values ​​for the condition of vehicle 1000 after the time of display. (3) In the above embodiment, the multiple types of display modes do not have to include a third type of display mode. That is, the multiple types of display modes may consist only of the first type of display mode M10 and the second type of display mode M20. (4) In the above embodiment, the vehicle 1000 is capable of four-wheel drive. However, the vehicle 1000 may be a vehicle capable of two-wheel drive only. Furthermore, the vehicle 1000 does not need to be equipped with a drive force adjustment device. (5) In the above embodiment, the display control device 600 may be provided in the vehicle control device 400. That is, the display control device 600 may be configured as part of the vehicle control device 400. (6) In the above embodiment, the automatic driving mode is when the vehicle control device 400 is the primary driver. More specifically, a state in which both the operation of the accelerator and brake and the operation of the steering wheel H are partially automated corresponds to the manual driving mode in this embodiment. However, a state in which both the operation of the accelerator and brake and the operation of the steering wheel H are partially automated may also be the automatic driving mode. In this case, the manual driving mode is a state in which either the operation of the accelerator and brake or the operation of the steering wheel H is partially automated. (7) In the above embodiment, the vehicle 1000 may be equipped with a plurality of display units 500. The plurality of display units 500 may all be located in front of the driver's seat, or some may be located in front of the passenger seat. The display control device 600 performs the processing shown in the flowchart of Figure 7 for each of the plurality of display units 500.
