Description

[Technical field]

[0001] The present disclosure relates to a display control device. [Background technology]

[0002] In four-wheel drive vehicles, as described in Patent Document 1, for example, there is a display device that allows the driver to visually check the distribution status of the driving force applied to each wheel. The display device informs the driver of the distribution status of the driving force. The display device encourages the driver to operate more appropriately by making the driver aware of how much driving force can be distributed to each wheel. In the following description, the function of such a display device is referred to as a driving force distribution display. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-11019 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a four-wheel drive vehicle is autonomous, the driver is not required to operate the vehicle himself, so there is a high possibility that displays other than the drive force distribution display will be desired. Therefore, there has been a demand for technology that can display the appropriate display on the display device according to the driving mode, whether manual or autonomous. [Means for solving the problem]

[0005] The present disclosure can be realized in the following forms.

[0006] (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 includes a display unit that displays information to a passenger. The display control device controls the display unit, and includes a plurality of display modes including a first type display mode that displays the vehicle status at the time of display, and a second type display mode that does not display the vehicle status at the time of display. When a first predetermined condition is satisfied, including the driving mode being switched from the manual driving mode in which the display unit has performed the display in the first type display mode to the automatic driving mode, the display control device performs display in the second type display mode on the display unit at the time of display in the automatic driving mode. By adopting such a configuration, the display control device of the present disclosure performs display in the second type display mode at the time of display in the autonomous driving mode. In the autonomous driving mode, the passenger is unlikely to be involved in driving, so the passenger is unlikely to want the first type display mode that displays the vehicle status at the time of display. Therefore, the display control device of the present disclosure increases the possibility that the display mode desired by the passenger can be displayed on the display unit according to the driving mode. (2) In the display control device of the above embodiment, the second type display mode may be a mode that displays statistics of the vehicle's status before the time of display. By adopting such a form, the display control device of the present disclosure performs display in the second type display mode at the time of display in the autonomous driving mode. A passenger who is not driving is more likely to desire statistics that represent the vehicle's status at the time of display in order to know the appropriateness of the driving performance due to autonomous driving, rather than the vehicle's status at the time of display. For example, the statistics are average fuel efficiency and average vehicle speed. Thus, the display control device of the present disclosure can know the appropriateness of the driving performance due to autonomous driving. (3) In the display control device of the above embodiment, the vehicle further includes a plurality of drive wheels as wheels to which a driving force is transmitted, and a driving force adjustment device that adjusts the driving force of each of the plurality of drive wheels. The first type display mode may include a driving force distribution display mode that indicates the driving force of each of the plurality of drive wheels. By adopting such a configuration, the display control device of the present disclosure can display the second type display mode desired by the driver in the autonomous driving mode, even when the display control device has the driving force distribution display mode as the first type display mode. (4) In the display control device of the above embodiment, the display control device may further store information on a frequency at which each of the second display modes is displayed during a predetermined first period, and when the first condition is satisfied, display the most frequently displayed display mode among the second display modes based on the frequency information. By adopting such an embodiment, the display control device of the present disclosure can display, on the display unit, a display mode that is likely to be desired by a passenger based on the frequency at which the display modes are displayed. (5) In the display control device of the above embodiment, the display control device may further store information on the time during which each of the second display modes was displayed during a predetermined first period, and when the first condition is satisfied, display the second display mode that was displayed for the longest time based on the time information. By adopting such an embodiment, the display control device of the present disclosure can display, on the display unit, a display mode that is likely to be desired by a passenger based on the display time of the display mode.

[0008] A. First embodiment: A-1. Configuration of the first embodiment: FIG. 1 is an explanatory diagram showing the configuration of the first embodiment. The display control device 600 is provided in a vehicle 1000. When the vehicle 1000 has a passenger, the vehicle 1000 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 includes a plurality of driving 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 required for the vehicle 1000 to travel to the road surface. That is, the multiple drive wheels 100 are wheels to which the driving force output by the drive unit 210 is transmitted. The multiple drive wheels 100 are composed of front wheels 110R and 110L as a pair of wheels arranged on the left and right sides of the vehicle 1000, and rear wheels 120R and 120L as a pair of wheels 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 an axle or a propeller shaft. In FIG. 1, illustrations related to the structure are omitted in order to facilitate understanding of the technology.

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

[0011] The drive unit 210 drives the vehicle 1000. The drive unit 210 is composed of, for example, an engine, a transmission, and a driving force adjustment device. In order to facilitate understanding of the technology, the drive unit 210 other than the driving force adjustment device is omitted from the illustration in FIG. 1.

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

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

[0014] The steering device 230 executes 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. Furthermore, 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 the communication line. Note that the information acquisition unit 300 sends information that is not related to the control of the vehicle 1000 only to the display control device 600.

[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 stores information required for controlling the vehicle 1000. The processor 410 loads the control program stored in the ROM 420 into the RAM 430 and executes it to realize various functions. 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 communication lines.

[0017] More specifically, the vehicle control device 400 controls the driving execution unit 200 in accordance with an automatic driving mode or a manual driving mode as a driving mode.

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

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

[0020] In the autonomous driving mode in this embodiment, the vehicle 1000 has a passenger. However, in the autonomous driving mode in this embodiment, the main driver is the vehicle control device 400. 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 transmits the status of the vehicle 1000 to the display control device 600. The status of the vehicle 1000 is, for example, the driving status and the external status. More specifically, the driving status is the amount of driving force distribution and the magnitude of acceleration and deceleration of the vehicle 1000, which will be described later. The external status is signs and obstacles present around the vehicle 1000, which are acquired by the information acquisition unit 300. Furthermore, the external status also includes traffic congestion and route information received by a navigation device.

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

[0023] Next, the display control device 600 shown in FIG. 1 will be described. The display control device 600 controls the display unit 500. The display control device 600 has a plurality of display modes as display modes to be displayed on the display unit 500. The display control device 600 displays one of the plurality of display modes on the display unit 500. The display control device 600 is composed of a processor 610, a ROM 620, and a RAM 630. Each configuration is the same as the processor 410, the ROM 420, and the RAM 430 in the vehicle control device 400. The function of the display control device 600 will be described in detail later.

[0024] A-2.Multiple display modes: The display control device 600 has a plurality of types of display modes, including a first type display mode M10, a second type display mode M20, and a third type display mode.

[0025] The first type 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. Thus, the first type display mode M10 displays the status of the vehicle 1000 in real time. The display control device 600 has a plurality of display modes as the first type display mode M10. For example, the first type display mode M10 includes a driving force distribution display mode M11 and an eco-driving indicator display mode M12.

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

[0027] The driving force distribution display mode M11 indicates the amount of driving force distribution at the time of display by the display unit 500. That is, the driving force distribution display mode M11 changes each scale in real time according to changes in the amount of driving force distribution.

[0028] FIG. 4 is an explanatory diagram showing the eco-driving indicator display mode M12. The eco-driving indicator display mode M12 shows the evaluation result of an environmentally friendly driving method. As shown in FIG. 4, the eco-driving indicator display mode M12 has three ranges. The eco-driving indicator display mode M12 shows the evaluation result of environmentally friendly driving by lighting up each range. More specifically, lighting up the range M12a shows the accelerator opening at the time of display. The range M12b is a range of accelerator opening that is evaluated as environmentally friendly driving. The range M12c is a range of accelerator opening that exceeds the range M12b.

[0029] The driving force distribution display mode M11 and the eco-drive indicator display mode M12 inform the driver in real time of the status of the vehicle 1000. Therefore, the driver can review the driving method in real time.

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

[0031] Fig. 5 is an explanatory diagram showing the average fuel efficiency display mode M21. The average fuel efficiency display mode M21 displays the average fuel efficiency of the vehicle 1000 in a predetermined measurement period. The predetermined measurement period is, for example, a period from when a switch is provided on the display unit 500 and turned on by a passenger to the present. This measurement period is also called a reset period. In Fig. 5, the average fuel efficiency in the measurement period of the vehicle 1000 is illustrated as "average fuel efficiency between resets."

[0032] 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 the vehicle 1000 during a measurement period. The predetermined measurement period is the same as the measurement period in the average fuel economy display mode M21.

[0033] The average fuel consumption display mode M21 and the average vehicle speed display mode M22 inform the passenger of statistics indicating the status of the vehicle 1000. By checking the statistics, the passenger can, for example, comprehensively evaluate the driving of the vehicle 1000 up to the time of the display.

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

[0035] A-3. Display control device processing: 7 is a flowchart showing the display process in the first embodiment. The functions of the display control device 600 will be 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] 7, the display control device 600 checks the driving mode. More specifically, when the driving mode is the automatic driving mode, the display control device 600 advances the process to step S120. When the driving mode is the manual driving mode, the display control device 600 advances the process to step S111.

[0037] 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 process of step S111, the display control device 600 ends the process of this flowchart.

[0038] 7, in the autonomous driving mode, the display control device 600 checks the display mode at the time of display on the display unit 500. 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 advances the process 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 advances the process to step S111.

[0039] 7, the display control device 600 performs display in the second type display mode M20 on the display unit 500. More specifically, the display control device 600 performs display in the second type display mode M20 when a predetermined first condition is satisfied, including the driving mode being switched from the manual driving mode in which the display in the first type display mode M10 was performed on the display unit 500 to the automatic driving mode. This process will be described in detail below.

[0040] In step S130 of FIG. 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 condition related to the driving mode. In step S130, the condition related to the driving mode is satisfied. The first condition includes the condition related to the other display modes in addition to the condition related to the driving mode. The condition related to the other display modes is, for example, a condition in which an instruction to display in the first type display mode M10 is not issued even in the automatic driving mode, or a condition in which an instruction to display in the third type display mode such as a video distributed through a communication line is not issued in the automatic driving mode. In other words, the condition related to the other display modes is a condition in which an instruction to display a display mode other than the second type display mode is not issued. Therefore, when the first condition is not satisfied, the display control device 600 advances the process to step S131. If the first condition is satisfied, the display control device 600 advances the process to step S140.

[0041] 7, the display control device 600 displays another display mode based on an instruction to display a display mode other than the second type display mode. For example, when an instruction is given to display in the first type display mode M10 even in the autonomous driving mode, the display control device 600 displays the first type display mode M10.

[0042] In step S140 of FIG. 7, the display control device 600 performs display in the second type display mode M20 on the display unit 500. In addition, when the second type display mode M20 includes a plurality of display modes, the display control device 600 displays, for example, the display mode that has the highest display frequency among the second type display modes M20. This frequency is the frequency at which each display mode of the second type display mode M20 is displayed in a predetermined first period. The first period is a period during which automatic driving is performed that is included in a predetermined time from the current time. For example, the first period is a period from the time of display to one month ago. In addition, the frequency information is stored in the RAM 630 of the display control device 600. Therefore, when the first condition is satisfied, the display control device 600 displays the display mode that has the highest display frequency among the second type display modes M20 based on the information on the frequency of display in the first period. After the process of step S140, the display control device 600 ends the process of this flowchart.

[0043] By adopting such a configuration, the display control device 600 of the present disclosure performs display in the second type display mode M20 at the time of display in the autonomous driving mode. In the autonomous driving mode, the passenger is unlikely to be involved in driving, and therefore the passenger is unlikely to desire the first type display mode M10 that displays the vehicle status at the time of display. Therefore, the display control device 600 of the present disclosure increases the possibility that the display mode desired by the passenger can be displayed on the display unit 500 according to the driving mode.

[0044] Furthermore, the display control device 600 of the present disclosure performs display in the second type display mode M20 at the time of display in the autonomous driving mode. A passenger who is not driving is more likely to desire statistics that represent the status of the vehicle 1000 at the time of display in order to know the appropriateness of the driving performance by autonomous driving, rather than the status of the vehicle 1000 at the time of display. For example, this statistics is average fuel consumption, average vehicle speed, etc. Therefore, the display control device 600 of the present disclosure can know the appropriateness of the driving performance by autonomous driving.

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

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

[0047] B. Second embodiment: In the first embodiment, the display control device 600 displays the most frequently displayed display mode among the second type display modes M20 as the process of step S140 in FIG. 7. However, when the first condition is satisfied, 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 mode M20 is displayed in a predetermined first period. The first period is the same as the first period in the first embodiment.

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

[0049] C. Third embodiment: In the above embodiment, the first type display mode M10 displays the status of the vehicle 1000 at the time of display, and the second type display mode M20 displays statistics of the status of the vehicle 1000 before the time of display. The display control device 600 in the third embodiment may further include a fourth type display mode that displays both the status of the vehicle 1000 at the time of display and statistics of the status of the vehicle 1000 before the time of display. For example, the fourth type display mode causes the display unit 500 to display the evaluation result in the eco-driving indicator display mode M12 and the average fuel efficiency in the average fuel efficiency display mode M21.

[0050] The display control device 600 of the third embodiment handles the fourth type display mode as the first type display mode M10 or the second type display mode M20 based on the size of the area displaying each piece of information, namely, the status of the vehicle 1000 at the time of display and the statistics of the status of the vehicle 1000 prior to the time of display. That is, in the process of Fig. 7, the fourth type display mode is handled as the first type display mode M10 when the information representing the status of the vehicle 1000 at the time of display is displayed most largely. Furthermore, the fourth type display mode is handled as the second type display mode M20 when the information representing the statistics of the status of the vehicle 1000 prior to the time of display is displayed most largely.

[0051] By adopting this configuration, the display control device 600 of the third embodiment can display on the display unit 500 the display mode that is likely to be desired by the occupant, even when the multiple display modes include a fourth display mode that displays the status of the vehicle 1000 at the time of display and statistics of the status of the vehicle 1000 prior to the time of display.

[0052] D. Other embodiments: (1) In the above embodiment, the display control device 600 includes, for example, a driving force distribution display mode M11 and an eco-driving indicator display mode M12 as the first type display mode M10. However, the display control device 600 may include one or more display modes as the first type display mode M10. That is, the display control device 600 may have only the driving force distribution display mode M11 as the single first type display mode M10. Similarly, with respect to the second type display mode M20, the display control device 600 may have one or more display modes as the second type display mode M20. That is, the display control device 600 may have only the average fuel consumption display mode M21 as the single second type display mode M20. (2) In the above embodiment, the second type display mode M20 displays statistics of the vehicle's status before the time of display. The second type display mode M20 may be in any form that does not display the status of the vehicle 1000 at the time of display. For example, the second type display mode M20 may display the status of the vehicle 1000 in a period that does not include the time of display. More specifically, the second type display mode M20 may display statistics of the vehicle 1000's status in a predetermined period prior to the time of display. Furthermore, for example, the second type display mode M20 may display a predicted value of the status of the vehicle 1000 after the time of display. (3) In the above embodiment, the multiple types of display modes do not have to include the third type display mode. That is, the multiple types of display modes may be only the first type display mode M10 and the second type display mode M20. (4) In the above embodiment, the vehicle 1000 is capable of running in four-wheel drive. However, the vehicle 1000 may be a vehicle that is only capable of running in two-wheel drive. Furthermore, the vehicle 1000 does not have to be equipped with a driving force adjustment device. (5) In the above embodiment, the display control device 600 may be provided in the vehicle control device 400. In other words, the display control device 600 may be configured as a part of the vehicle control device 400. (6) In the above embodiment, the autonomous driving mode is a case where the vehicle control device 400 is the main driver of the vehicle. 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 autonomous 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 include a plurality of display units 500. For example, all of the plurality of display units 500 may be disposed in front of the driver's seat, or some of the display units 500 may be disposed in front of the passenger seat. The display control device 600 performs the process of the flowchart in FIG. 7 for each of the plurality of display units 500. (8) In the above embodiment, the first period is not limited to one month from the time of display. The first period may be one week before the time of display. Furthermore, by providing a switch in the display control device 600, the first period may be from a time based on the operation of the switch by the passenger to the time of display. (9) In the above embodiment, the driving force adjustment unit 411 is included in the processor 410 of the vehicle control device 400.
