Description

[Technical field]

[0001] The present invention relates to a vehicle display device, a vehicle, a display processing method, and a program. [Background technology]

[0002] Patent Document 1 discloses a vehicle display device that displays on a display or head-up display device the operations (lane change, lane merging, lane branching, etc.) that are scheduled to be performed by the vehicle on a route that guides the vehicle to a destination. The display of the operations includes the distance to the location where the operation is scheduled to be performed, the type of operation (lane change, lane merging, lane branching, etc.), and the type of automatic or manual driving.

[0003] In addition, on this display device, multiple actions are displayed from bottom to top, starting with the action that is closest in terms of the planned location (distance) to be performed, and the bottom most action that has been completed is erased and a new action is added and displayed at the top. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-088222 Summary of the Invention [Problem to be solved by the invention]

[0005] In the vehicle display device described in Patent Document 1, even if an action under automatic driving control is displayed as the immediate action, there are cases where the action cannot be performed under automatic driving due to road conditions, etc. In such cases, the vehicle display device displays an action under manual driving instead of the action under automatic driving control.

[0006] In this case, the display screen does not change the notation of the type of operation, and only changes the notation of automatic driving control to manual driving, so there is a risk that the occupants will not be able to understand the change in the display.

[0007] In other words, there is a risk that the occupant may not be able to grasp the situation when he or she is required to perform the above-mentioned actions (driving operations) manually.

[0008] In other words, there is room for improvement in terms of making the occupant aware that the plan to be implemented displayed on the vehicle display device has been changed. In this regard, it is desirable for the occupant to be able to know in advance that the plan to be implemented may be changed.

[0009] In consideration of the above, an object of the present invention is to provide a vehicle display device, a vehicle, a display processing method, and a program that allow an occupant to know in advance the possibility that a plan to be implemented will be changed. [Means for solving the problem]

[0010] A vehicle display device according to a first aspect includes a display unit that is provided within the vehicle cabin and has a specific display area in which multiple plans to be implemented in the vehicle are displayed in the display area in the order in which they are scheduled to be implemented, and a control unit that displays, in the specific display area, a first plan that is one of the multiple plans, and a second plan that is scheduled to be implemented after the first plan, and an alternative plan that may be implemented in place of the first plan.

[0011] In this vehicle display device, a display unit is provided in the vehicle cabin. A specific display area within the display area of ​​the display unit displays multiple plans to be implemented in the vehicle in the order in which they are scheduled to be implemented. A control unit displays, in the specific display area, an alternative plan that may be implemented in place of the first plan between a first plan, which is one of the multiple plans, and a second plan, which is the plan to be implemented next after the first plan.

[0012] Therefore, by simply looking at the specific display area of ​​the display unit, the occupant can know that there is a possibility that the alternative plan will be implemented in place of the first plan to be implemented. As a result, even if the first plan to be implemented is changed to the alternative plan, the occupant can understand the change in plan because the occupant is aware in advance of the possibility that the plan will be changed. In other words, the occupant is prevented or suppressed from being unable to understand the change in plan.

[0013] A second aspect of the present invention relates to a vehicle display device according to the first aspect, wherein the first plan is a top plan that is a plan to be implemented first among the plurality of plans.

[0014] In this vehicle display device, the control unit displays an alternative plan for the top plan that is scheduled to be implemented first among the multiple displayed plans. In other words, by displaying an alternative plan for the top plan that is scheduled to be implemented earliest, even if the top plan that is scheduled to be implemented first is changed to the alternative plan, the occupant is aware in advance of the possibility that the top plan will be changed, and is therefore able to understand the change in the top plan. In other words, the occupant is prevented or suppressed from being unable to understand the change in the top plan.

[0015] A third aspect of the vehicle display device is the vehicle display device of the second aspect, wherein the first plan is a vehicle operation performed by driving assistance control, and when a predetermined condition is met for the first plan, the control unit displays the alternative plan, which is a vehicle operation performed by the same type of manual operation as the first plan, in the specific display area.

[0016] In this vehicle display device, when a first plan is vehicle operation through driving assistance control and a specified condition is met for the first plan, the control unit additionally displays an alternative plan in a specific display area, the alternative plan being vehicle operation through the same type of manual operation as the first plan.

[0017] That is, when a predetermined condition is satisfied for the vehicle operation by the driving assistance control, which is the first plan, for example, when it is found that the vehicle operation by the driving assistance control is highly likely to be impossible, an alternative plan, which is the vehicle operation by the same kind of manual operation as the first plan, is displayed in the specific display area. This allows the occupant to know in advance that there is a possibility of switching to manual driving if the vehicle operation (driving assistance control) of the first plan is difficult.

[0018] Therefore, when the plan to be implemented is changed from the first plan to the alternative plan, the change in plan can be reliably understood and the occupants can calmly carry out manual driving.

[0019] A vehicle display device according to a fourth aspect is the vehicle display device according to any one of the first to third aspects, wherein the control unit displays the alternative plan in a color different from at least the first plan.

[0020] In this vehicle display device, the alternative plan is displayed in a specific display area in a color different from at least the first plan. Therefore, a passenger who visually checks the specific display area of ​​the display unit can intuitively confirm that the alternative plan is not the plan currently being implemented, but is a candidate for an alternative to the first plan being implemented. In addition, because the alternative plan is displayed next to the first plan, the passenger can easily confirm that the alternative plan is a candidate for an alternative to the first plan.

[0021] A fifth aspect of the vehicle display device is the vehicle display device of the second or third aspect, wherein when the control unit adds and displays the alternative plan in the specific display area, it erases the last plan, which is the plan that is scheduled to be implemented last among the multiple plans, in the specific display area.

[0022] In this vehicle display device, when the control unit inserts (adds) an alternative plan between a first plan and a second plan displayed side by side in a specific display area, the last plan is erased to ensure space in the specific display area to display the alternative plan.

[0023] By processing in this manner, the number of plans displayed in the specific display area is kept constant.

[0024] A sixth aspect of the vehicle display device is a vehicle display device according to any one of the first to fifth aspects, wherein the control unit erases the alternative plan from the specific display area when operation of the first plan is started.

[0025] In this vehicle display device, when the operation of the first plan is started, the control unit erases the alternative plan from the specific display area. In other words, the start of the operation of the first plan means that the possibility of implementing the alternative plan in place of the first plan has disappeared. Therefore, by erasing the alternative plan that cannot be implemented from the specific display area, it is possible to reliably inform the occupants that the possibility of implementing the alternative plan has disappeared.

[0026] A seventh aspect of the vehicle display device is the vehicle display device of the third aspect, wherein the specified condition for the first plan is when vehicle operation related to the first plan is not started at the scheduled timing for executing the first plan.

[0027] In this vehicle display device, when the operation of the first plan cannot be started at the scheduled execution timing of the first plan, an alternative plan is displayed in the specific display area. In other words, if the operation of the first plan cannot be executed at the scheduled execution timing, it is highly likely that the operation of the first plan cannot be executed during the postponement of the scheduled execution timing.

[0028] Therefore, by displaying an alternative plan when an operation cannot be started at the scheduled timing of the first plan, the occupant can know that the alternative plan will be implemented instead of the first plan by simply looking at the specific display area of ​​the display unit. As a result, even if the first plan to be implemented is changed to the alternative plan, the occupant can understand the change in plan because he or she is aware in advance of the possibility that the plan will be changed. In other words, the occupant is prevented or suppressed from being unable to understand the change in plan.

[0029] The eighth aspect of the vehicle display device is the vehicle display device of the third aspect, wherein the specified condition for the first plan is when there is a possibility that vehicle operation related to the first plan will not be started at the scheduled timing for implementing the first plan.

[0030] In this vehicle display device, when there is a possibility that the operation of the first plan cannot be started at the scheduled execution timing of the first plan, an alternative plan is displayed in the specific display area. In other words, when there is a high possibility that the operation of the first plan cannot be executed at the scheduled execution timing, there is a high possibility that the vehicle operation of the first plan cannot be executed even when the scheduled execution timing arrives.

[0031] Therefore, by displaying an alternative plan when there is a high possibility that the operation cannot be started at the scheduled timing of the first plan, the occupant can understand that the alternative plan may be implemented instead of the first plan by simply looking at the specific display area of ​​the display unit. As a result, even if the first plan to be implemented is changed to the alternative plan, the occupant can understand the change in plan because he or she is aware in advance of the possibility that the plan will be changed. In other words, the occupant is prevented or suppressed from being unable to understand the change in plan.

[0032] A ninth aspect of the present invention relates to the vehicle display device of any one of the first to eighth aspects, and the display unit is provided in an instrument panel in front of a driver's seat.

[0033] In this vehicle display device, the display unit is provided on the instrument panel in front of the driver's seat, so that the occupant can check the plan in the order in which it is scheduled to be carried out without having to move their line of sight significantly while driving.

[0034] A vehicle display device according to a tenth aspect is the vehicle display device according to any one of the first to eighth aspects, wherein the display unit is a projection surface onto which an image is projected by a head-up display device.

[0035] In this vehicle display device, the display unit is a projection screen projected by a head-up display device, and multiple plans are displayed on the projection screen above the vehicle in the order of their execution. This allows a driver while driving to check multiple plans that are soon to be executed without moving their line of sight significantly.

[0036] A vehicle according to an eleventh aspect includes the display device for vehicle according to any one of the first to tenth aspects.

[0037] Since the vehicle includes the vehicle display device according to any one of the first to tenth aspects, the driver can confirm that the alternative plan may be added to the implementation schedule in place of the first plan simply by visually checking the alternative plan displayed in the specific display area. Therefore, the driver will not be taken by surprise even if the first plan is switched to the alternative plan.

[0038] A display processing method according to a twelfth aspect is a display processing method that is provided in a vehicle cabin and causes a display unit having a display area to display multiple plans to be implemented in the vehicle in a specific display area of ​​the display area in order of scheduled implementation, and includes a step of displaying, in the specific display area, an alternative plan that may be implemented in place of the first plan between a first plan, which is one of the multiple plans, and the second plan, which is scheduled to be implemented next after the first plan.

[0039] According to this display processing method, the same advantageous effects as those of the first aspect are achieved.

[0040] The program of the 13th aspect is a program provided in a vehicle cabin and causes a display unit having a display area to display multiple plans to be implemented in the vehicle in a specific display area of ​​the display area in the order in which they are scheduled to be implemented, and causes a computer to perform processing including a step of displaying, in the specific display area, an alternative plan that may be implemented in place of the first plan, between a first plan, which is one of the multiple plans, and the second plan, which is scheduled to be implemented next after the first plan.

[0041] By executing this program on a computer, the same effects as those of the first aspect can be achieved. Effect of the Invention

[0042] As described above, according to the display devices for a vehicle according to the first to eighth aspects, the occupant can know in advance the possibility that the plan to be implemented will be switched.

[0043] According to the vehicle display device of the ninth and tenth aspects, a driver can check the plans displayed in order of scheduled implementation without moving his / her line of sight significantly while driving.

[0044] According to the vehicle of the eleventh aspect, the occupant can know in advance the possibility that the plan to be implemented will be changed.

[0045] According to the display processing method of the twelfth aspect, the occupant can know in advance the possibility that the plan to be implemented will be switched.

[0046] According to the program according to the thirteenth aspect, the occupant can know in advance the possibility that the plan to be implemented will be switched. [Brief description of the drawings]

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. In this embodiment, the ROM 32 or the storage 36 stores programs for performing display processing, various data, and the like.

[0058] The communication interface 38 is an interface for the vehicle display device 10 to communicate with a server and other devices (not shown), and uses standards such as Ethernet (registered trademark), LTE, FDDI, and Wi-Fi (registered trademark).

[0059] A head-up display device 44 that projects images on the first display unit 24 and the second display unit 26, and an actuator 46 are connected to the input / output interface 40. The actuator 46 includes a steering actuator, an accelerator actuator, and a brake actuator, and the steering actuator steers the vehicle 12. The accelerator actuator accelerates the vehicle 12. The brake actuator controls the brakes to decelerate the vehicle 12. Sensors and a GPS device (not shown) for automatically driving the vehicle 12 are also connected to the input / output interface 40.

[0060] (Functional configuration of the vehicle display device 10)

[0061] 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 with reference to FIG.

[0062] 3, the vehicular display device 10 includes, as functional components, a communication unit 50, an operation plan setting unit 52, an automatic driving control unit 54, a detection unit 55, a first display instruction unit 56, a second display instruction unit 58, and an emphasis display unit 60. Each functional component is realized by the CPU 30 reading and executing a program stored in the ROM 32 or the storage 36.

[0063] The communication unit 50 transmits and receives data to and from an external server and other devices via the communication interface 38. For example, the communication unit 50 transmits and receives map data stored in a server and data on traffic conditions, etc. The communication unit 50 may also be configured to perform vehicle-to-vehicle communication with surrounding vehicles.

[0064] The operation plan setting unit 52 sets an operation plan for the vehicle 12. Specifically, the operation plan setting unit 52 sets an operation plan from the current location to the destination by inputting the destination by the occupant.

[0065] The automatic driving control unit 54 automatically drives the vehicle 12 according to a set operation plan while taking into consideration the position information and environmental information around the vehicle 12. Specifically, the automatic driving control unit 54 controls the actuator 46 to automatically drive the vehicle 12.

[0066] The detection unit 55 detects the current location of the vehicle 12 from sensors and a GPS device, etc., and detects drive signals for the actuator 46, etc., and detects whether or not the operation of the plan has started when the vehicle passes the location where the plan is scheduled to be implemented, etc.

[0067] The first display instruction unit 56 causes the first display unit 24 to display a plan for the vehicle 12 based on the operation plan set by the operation plan setting unit 52. The function of the first display instruction unit 56 will be described with reference to Figs. 4(B), 5(B), and 6(B).

[0068] As shown in FIG. 4(B), the set speed VA during cruise control and the current vehicle speed VB of the vehicle 12 are displayed in the upper part of the display area 24A of the first display unit 24. The set speed VA and the vehicle speed VB are displayed on the left side of the vehicle width direction in the display area 24A of the first display unit 24. The set speed VA is displayed small in the lower part, and is set to 120 km / h here as an example. The current vehicle speed VB is displayed in the upper part, and is displayed as 58 km / h. Therefore, the vehicle 12 is set to travel at a speed of up to 120 km / h while maintaining a constant distance from the vehicle ahead.

[0069] On the left side of the display area 24A of the first display unit 24, an image V1 simulating the vehicle itself and images V2 and V3 simulating surrounding vehicles are displayed on the road image R. When the image V1 is viewed, it is possible to see that the vehicle itself is traveling in the middle lane of the three lanes of the road image R. The images V2 and V3 are each displayed based on information detected by sensors (not shown) mounted on the vehicle 12. When the images V2 and V3 are viewed, it is possible to see that vehicles are traveling diagonally to the right of the vehicle itself and in front of the vehicle itself. The position of the vehicle itself can be detected by a GPS device mounted on the vehicle 12. In addition, a combination of sensors such as a stereo camera, an ultrasonic sensor, a millimeter wave radar, and a laser radar is used as a sensor for detecting surrounding vehicles. In addition, the position of the vehicle itself and the positions of the surrounding vehicles may be grasped by performing vehicle-to-vehicle communication with surrounding vehicles.

[0070] On the right side of the display area 24A of the first display unit 24, a specific display area 24B is set by the first display instruction unit 56 to display the plan of the vehicle 12, and multiple plans to be executed are displayed in the specific display area 24B. In this embodiment, as an example, three plans, a first plan P1, a second plan P2, and a third plan P3, are displayed in order from the bottom. In addition, each plan displays three pieces of information: a distance from a current position to a position where an action is scheduled to be executed, a planned driving route, and a type of driving. The type of driving here refers to a type of action that is performed manually by a driver or an action that is performed by automatic driving. In addition, in this embodiment, as an example, only the most recent three plans are displayed, and subsequent plans are not displayed, but this is not limited to this. For example, four or more plans may be displayed on the first display unit 24. In addition, the number of plans (however, multiple) to be displayed on the first display unit 24 may be set arbitrarily.

[0071] Below, the first plan P1, the second plan P2, and the third plan P3 will be explained in detail.

[0072] As shown in FIG. 4(B), "100m" is displayed to the left of the first plan P1, indicating that the operation will be performed approximately 100m ahead from the current position. In addition, a schematic diagram of a lane change from the left lane to the right lane is displayed in the center of the first plan P1, and this schematic diagram allows the user to understand the planned driving route. Furthermore, "ASSIST" is displayed to the right of the first plan P1, indicating that the operation will be performed (implemented) by automated driving (driving assistance control).

[0073] The first plan P1 is displayed slightly larger than the second plan P2 and the third plan P3 described later. The first plan P1 corresponds to the "top plan."

[0074] Meanwhile, the second plan P2 is displayed above the first plan P1. On the left of the second plan P2, "500m" is displayed, indicating that the action will be taken (implemented) about 500m ahead from the current position. In addition, in the center of the second plan P2, a schematic diagram of the route merging from the side road on the right to the main road is displayed, and this schematic diagram makes it possible to understand the planned route to be traveled. Furthermore, on the right side of the second plan P2, "ASSIST" is displayed, indicating that the action will be taken (implemented) by automated driving (driving assistance control).

[0075] The third plan P3 is displayed above the second plan P2. On the left of the third plan P3, "800m" is displayed, indicating that the action will take place (be carried out) approximately 800m from the current position. In addition, in the center of the third plan P3, a schematic diagram of a lane change from the left lane to the right lane is displayed, and this schematic diagram makes it possible to understand the planned driving route. Furthermore, on the right side of the third plan P3, "ASSIST" is displayed, indicating that the action will be carried out by autonomous driving (driving assistance control).

[0076] The third plan P1 corresponds to the "last plan."

[0077] It should be noted that the first plan P1 to the third plan P3 are all actions performed by automatic driving, but in the case of actions performed by manual driving, "MANUAL" is displayed instead of "ASSIST" to the right of each plan.

[0078] Fig. 5(B) shows an image on the first display unit 24 when the vehicle 12 has traveled about 100 m from the state shown in Fig. 4(B). As shown in Fig. 5(B), the left display of the first plan P1 has been changed to "0 m", the left display of the second plan P2 has been changed to "400 m", and the left display of the third plan P3 has been changed to "700 m".

[0079] The other display contents are the same as those in FIG.

[0080] In Figure 10(B), the first plan P1 has been erased from the state shown in Figure 5(B), the second plan P2 and the third plan P3 have each been moved down one level, and the fourth plan P4, which is scheduled to be implemented next after the third plan P3, is displayed above the third plan P3.

[0081] On the left of the fourth plan P4, "1.5km" is displayed, indicating that the action will be performed (implemented) approximately 1.5km from the current location. In addition, in the center of the fourth plan P4, a schematic diagram of the route merging from the side road on the right to the main road is displayed, and this schematic diagram allows the user to understand the planned route. Furthermore, on the right side of the fourth plan P4, "ASSIST" is displayed, indicating that the action will be performed (implemented) by autonomous driving (driving assistance control).

[0082] The other display contents are the same as those in FIG.

[0083] Figure 6 (B) is a diagram showing a state in which a fifth plan P5, which may replace the first plan P1, is displayed between the first plan P1 and the second plan P2 when the detection unit 55 detects that the operation of the first plan P has not started at the planned implementation position of the first plan P1, which is the position shown in Figure 5 (B).

[0084] In FIG. 6(B), the fifth plan P5 is displayed above the first plan P1. To the left of the fourth plan, "50m" is displayed, indicating that this is an action that may occur (be carried out) approximately 50m ahead from the current position. In addition, in the center of the fifth plan P5, a schematic diagram of a lane change from the left lane to the right lane is displayed, and this schematic diagram allows the user to understand the planned travel route. Furthermore, to the right of the fifth plan P5, "MANUAL" is displayed, indicating that this is an action that will be carried out by manual driving.

[0085] Moreover, unlike the other plans (first plan P1, second plan P2), the fifth plan P5 is displayed in a grayed-out (light gray) state in the specific display area. This is shown in Fig. 6(B) by the dashed outer frame of the fifth plan P5. This indicates that at this stage it is not a plan to be implemented (it may become a plan to be implemented), and indicates that it is an alternative plan to the first plan P1 located below the fifth plan P5.

[0086] The other display contents are the same as those in FIG.

[0087] FIG. 7(B) shows an image on first display unit 24 when vehicle 12 has traveled approximately 50 m from the state shown in FIG. 6(B).

[0088] As shown in Figure 7 (B), in the specific display area 24B, the first plan P1 has been erased from the state in Figure 6 (B), the fifth plan P5 and the second plan P2 have moved downward, and the third plan P3, which had been erased by the addition of the fifth plan P5, has been restored to the top row and is now displayed.

[0089] In addition, the fifth plan P5, which was previously displayed in gray, is now displayed in the same way as the other plans (the second plan P2 and the third plan P3).

[0090] The displays on the left of the fifth plan P5, the second plan P2, and the third plan P3 have been changed to "0m," "350m," and "650m."

[0091] In other words, since the operation of the first plan P1 could not be started even after passing the position where the first plan P1 was scheduled to be implemented, the fifth plan P5, which is an alternative plan and is a manual operation plan, was implemented.

[0092] After passing the planned implementation position, if the first plan P1 is implemented, the state returns to that of FIG. 5(B).

[0093] The other display contents are the same as those in FIG.

[0094] Next, the second display instruction unit 58 will be described.

[0095] 3, the vehicle display device 10 includes, as a functional configuration, a second display instruction unit 58. The second display instruction unit 58 is configured to display, on the second display unit 26, the two plans that are scheduled to be implemented earliest among the plans displayed on the first display unit 24 by the first display instruction unit 56.

[0096] The highlighting unit 60 has the function of highlighting (enlarging) the plan that is scheduled to be implemented earliest (hereinafter referred to as the "top plan") more than the other plans when multiple plans are displayed in the specific display areas 24B, 26B of the first display unit 24 and the second display unit 26, respectively.

[0097] As shown in Fig. 4(B), the first plan P1 (see Fig. 4(B)) and the fourth plan P2 (see Fig. 7(B)) which are the top plans are displayed slightly enlarged compared to the other plans in the specific display area 24B of the first display unit 24 by the function of the highlighting unit 60. For example, the enlargement is about 110%.

[0098] On the other hand, when a plurality of plans are displayed on the second display unit 26, the highlighting unit 60 displays the most recent plan on the second display unit 26 in a more highlighted manner than the other plans.

[0099] The functions of the second display instruction section 58 and the highlighting section 60 will be described with reference to Figs. 4(A) to 7(A) and 10(A). Images displayed on the second display section 26 that are substantially similar to images displayed on the first display section 24 are given the same reference numerals, and detailed descriptions thereof will be omitted. Images displayed on the second display section 26 that are substantially similar to images displayed on the first display section 24 display content synchronized with the display on the first display section 24.

[0100] As shown in FIG. 4(A), the set speed VA during cruise control and the current vehicle speed VB of the vehicle 12 are displayed at the bottom of the display area 26A of the second display unit 26. The set speed VA and the vehicle speed VB are displayed on the left side of the vehicle width direction in the display area 26A of the second display unit 26. The set speed VA is displayed on the right side, and is set to 120 km / h here as an example. The current vehicle speed is displayed on the left side, and is displayed as 58 km / h. Therefore, the vehicle 12 is set to travel at a speed up to 120 km / h while maintaining a certain distance from the vehicle ahead. The display of the set speed and the vehicle speed is synchronized with the contents of the first display unit 24.

[0101] On the right side of the display area 26A of the second display unit 26, a specific display area 26B is set by the second display instruction unit 58 to display the plan of the vehicle 12, and multiple plans to be executed (the first plan P1 and the second plan P2 to be executed next) are displayed in the specific display area 26B. The first plan P1, which is the most recent plan, is displayed below. As shown in FIG. 4(A), this first plan P1 is displayed enlarged compared to the other plans (the second plan P2), and the distance of 100 m to the first plan P1 is written on the lower side, and a schematic diagram of a lane change from the left lane to the right lane is displayed above the distance of 100 m, and "ASSIST" indicating automatic driving is displayed on the right side of the schematic diagram.

[0102] In addition, in the display area 26A of the second display unit 26, a second plan P2 is displayed above the first plan P1.

[0103] FIG. 5(A) is a diagram showing a state where the vehicle 12 has traveled 100 m from FIG. 4(A).

[0104] In Figure 10(A), the first plan P1 has been erased from the state shown in Figure 5(A), the second plan P2 has been moved down, and the third plan P3, which is scheduled to be implemented next after the second plan P2, is displayed above the second plan P2.

[0105] The other display contents are substantially the same as those in FIG.

[0106] FIG. 6(A) is a diagram showing a state in which the second plan P2 has been erased from the display area 26A of the second display unit 26 in FIG. 5(A) and then the fifth plan P5 has been inserted above the first plan P1.

[0107] Fig. 7(A) is a diagram showing the state at a position where the vehicle 12 has advanced 50 m from the state of Fig. 6(A). In the case of this figure, the first plan P1 could not be implemented at the implementation set position, and subsequent attempts to implement it were unsuccessful, so the first plan P1 was determined to be unimplementable, and the fifth plan P5 was set as the plan to be implemented.

[0108] As a result, the fifth plan P5, which was previously displayed grayed out, will be changed to the same display state as the other plan (the second plan P2).

[0109] (action)

[0110] Next, the operation of this embodiment will be described.

[0111] (Display processing)

[0112] An example of a display process for displaying a plan of the vehicle 12 based on an operation plan will be described with reference to the flowcharts shown in Figures 8 and 9. This display process is performed by the CPU 30 reading a display program from the ROM 32 or storage 36, expanding it in the RAM 34, and executing it.

[0113] 8, the CPU 30 determines whether or not a destination has been set in step S102. The destination may be directly input to the vehicle 12 by a passenger, or may be indirectly input via a mobile terminal or the like.

[0114] If the CPU 30 determines in step S102 that a destination has been set, the process proceeds to step S104. If the CPU 30 determines in step S102 that a destination has not been set, the display process ends.

[0115] In step S104, the CPU 30 sets an operation plan for the vehicle 12. Specifically, the CPU 30 sets an operation plan from the current location to the destination by using the function of the operation plan setting unit 52. When setting the operation plan, information on traffic conditions and accidents may be acquired and reflected. In addition, the operation plan may be set so that more automatic driving is performed in response to the passenger's requests input in advance.

[0116] In step S106, the CPU 30 causes the first display unit 24 and the second display unit 26 to display the plan. Specifically, the CPU 30 causes the first display unit 24 and the second display unit 26 to display the plan for the vehicle 12 based on the operation plan by the functions of the first display instruction unit 56 and the second display instruction unit 58, respectively.

[0117] As an example, as shown in Fig. 4(B), the CPU 30 displays three plans, a first plan P1, a second plan P2, and a third plan P3, in a specific display area 24B set to the right of the display area 24A of the first display unit 24. Similarly, as shown in Fig. 4(A), the CPU 30 displays three plans, a first plan P1 and a second plan P2, in a specific display area 26B set to the right of the display area 26A of the second display unit 26.

[0118] At this time, the CPU 30, by using the function of the highlighting unit 60, displays the first plan P1, which is the top plan, in a slightly enlarged manner in the specific display area 24B of the first display unit 24, as shown in Figure 4 (B), compared to the displays of the other plans (the second plan P2, the third plan P3).

[0119] Similarly, by using the function of the highlighting unit 60, the CPU 30 displays the first plan P1, which is the top plan, in an enlarged manner in the specific display area 26B of the second display unit 26, as shown in Figure 4 (A), compared to the displays of the other plans (the second plan P2).

[0120] In step S108, the CPU 30 determines whether or not the vehicle 12 has reached a planned execution position of the operation of the top plan (first plan P1) by using the function of the detection unit 55. For example, the current position of the vehicle 12 is confirmed by using the function of the communication unit 50 or the like, and determines whether or not the vehicle 12 has reached a planned execution position of the operation.

[0121] If the determination in step S108 is affirmative, the process proceeds to step S110. On the other hand, if the determination in step S108 is negative, the process waits until the determination is affirmative.

[0122] In step S110, the CPU 30 determines whether or not the operation of the top plan (first plan P1) has been started, using the function of the detection unit 55. Of the plans P1 to P3 displayed on the first display unit 24 shown in Fig. 4(B), it determines whether or not the operation (lane change control (driving assistance control)) of the first plan P1, which is the top plan, has been started, based on a drive signal for the actuator 46, etc. For example, in the case of a lane change, it is determined that the lane change control (driving assistance control), which is the first plan P1, has been started by detecting a blinking drive signal of the direction indicator with the detection unit 55.

[0123] If the determination in step S110 is affirmative, the process proceeds to step S112, and if the determination is negative, the process proceeds to step S114.

[0124] In step S112, the CPU 30 updates the display of the plan in the specific display areas 24B, 26B of the first display unit 24 and the second display unit 26 through the functions of the first display instruction unit 56 and the second display instruction unit 58.

[0125] Specifically, as shown in FIG. 10(B), in the specific display area 24B, the display of the first plan P1, which is the top action plan from the state of FIG. 5(B), is removed, the second plan P2 and the third plan P3 are moved one step downward, and the fourth plan P4, which is scheduled to be implemented next after the third plan P3, is newly displayed at the top.

[0126] Also, as shown in Figure 10(A), in the specific display area 26B, the display of the first plan P1, which is the top action plan from the state of Figure 5(A), is removed, the second plan P2 is moved downward and enlarged, and a third plan P3 is newly displayed above the second plan P2.

[0127] Hereinafter, this same display control will be referred to as "plan display update" and detailed description will be omitted.

[0128] In this way, when the display of the plan on the first display unit 24 and the second display unit 26 is updated in step S112, the process returns to step S108.

[0129] 9, the CPU 30 creates an alternative plan that may be implemented in place of the first plan P1, which is the top plan, by using the function of the operation plan setting unit 52. The alternative plan, a fifth plan P5, is similar to the first plan P1, but differs in the following respects.

[0130] That is, the fifth plan P5 is scheduled to be carried out at a location 50 m farther away than the first plan P1. Also, the first plan P1 is an automatic operation (see Fig. 6 (A) and (B), the notation "ASSIST"), but the fourth plan P4 is a manual operation (see Fig. 6 (A) and (B), the notation "MANUAL").

[0131] Next, in step S116, the CPU 30 uses the functions of the first display instruction unit 56 and the second display instruction unit 58 to display (insert) the fifth plan P5 in each of the specific display areas 24B, 26B of the first display unit 24 and the second display unit 26.

[0132] Specifically, as shown in Fig. 6(B), in the specific display area 24B of the first display unit 24, the third plan P3 is erased from the state of Fig. 5(B), the second plan P2 is moved upward, and the fifth plan P5 is inserted and displayed between the first plan P1 and the second plan P2. At this time, the fifth plan P5 is displayed in a grayed-out display (light gray).

[0133] Similarly, as shown in Fig. 6(A), in the specific display area 26B of the second display unit 26, the second plan P2 is erased from the state of Fig. 5(A) and the fifth plan P5 is displayed on the first plan P1. At this time, the fifth plan P5 is displayed in a grayed-out display (light gray).

[0134] By graying out the fifth plan P5 in this manner, it is indicated that the fifth plan P5 is not a plan scheduled to be implemented, but has the potential to be used as an alternative if the first plan P1 becomes impossible to implement.

[0135] In addition, the fifth plan P5 is displayed directly above the first plan P1, thereby indicating that it is an alternative plan to the first plan P1.

[0136] Next, in step S118, the CPU 30 determines, by the function of the detection unit 57, whether or not the operation of the top plan (first plan P1) has been started.

[0137] This is to determine whether the operation of the top plan (e.g., the first plan P1) can be carried out even after the vehicle 12 has passed the planned implementation point of the top plan (e.g., the first plan P1), while still traveling a predetermined distance (e.g., up to the display change position described below).

[0138] If the determination in step S118 is affirmative, the process proceeds to step S120, and if the determination is negative, the process proceeds to step S126.

[0139] Next, in steps S120 and S122, the CPU 30, using the functions of the first display instruction unit 56 and the second display instruction unit 58, erases the alternative plan, plan P5, from each specific display area 24B, 26B of the first display unit 24 and the second display unit 26, and adds the next plan to be implemented.

[0140] Specifically, as shown in Figure 5(B), in the specific display area 24B, the display of the fifth plan P5 is erased from the state of Figure 6(B), the second plan P2 is moved one step downward, and the third plan P3 is displayed above the second plan P2.

[0141] Similarly, as shown in FIG. 5(A), in the specific display area 26B, the display of the fifth plan P5 from the state of FIG. 6(A) is erased, and the second plan P2 is displayed above the first plan P1.

[0142] Next, in step S124, the CPU 30 uses the functions of the first display instruction unit 56 and the second display instruction unit 58 to update the display of the plan in the specific display areas 24B and 26B after a predetermined time has elapsed since the start of the operation of the top plan.

[0143] This is because, although it would be possible to update the display of the plan at the same time as the top plan begins to operate, in that case, the top plan (first displayed plan P1) and the alternative plan (fifth plan P5) would disappear from the specific display areas 24B, 26B at once, which could confuse the occupants.

[0144] When the display update of the plan is completed in step S124, the process returns to step S108.

[0145] Meanwhile, in step S126, the CPU 30 determines whether or not the vehicle 12 has reached the display change position by the function of the detection unit 55. For example, the current position of the vehicle 12 is confirmed by the function of the communication unit 50 or the like, and determines whether or not the vehicle 12 has reached the display change position.

[0146] Here, the display change position is a position at which it is determined to give up on implementing the top plan and to set the alternative plan as the implementation scheduled plan, and is set to a position before the implementation scheduled position of the alternative plan.

[0147] If a negative determination is made in step S126, the process returns to step 118. This is for the purpose of continuing to try whether the operation of the top plan can be started until the vehicle 12 reaches the display change position.

[0148] On the other hand, if the determination in step S126 is affirmative, the process proceeds to step S128.

[0149] In steps S128 and S130, the CPU 30 uses the functions of the first display instruction unit 56 and the second display instruction unit 58 to change the display so that the alternative plan is the implementation-scheduled plan.

[0150] Specifically, as shown in Figure 7(B), in the specific display area 24B, the display of the first plan P1 is erased from the state of Figure 6(B), the fifth plan P5 and the second plan P2 are moved downward one step at a time, and the third plan P3 is displayed above the second plan P2.

[0151] Similarly, as shown in Figure 7(A), in the specific display area 26B, the display of the first plan P1 is erased from the state of Figure 6(A), the fifth plan P5 is moved downward, and the second plan P2 is displayed above the fifth plan P5.

[0152] The states shown in FIGS. 7(A) and (B) are displays of the vehicle 12 at the time of reaching the planned implementation position of the fifth plan P5.

[0153] In this manner, when the display change of the plan is completed in steps 128 and 130, the process returns to step .

[0154] In this way, when there is a possibility that the top plan (e.g., the first plan P1) displayed in the specific display area 24B, 26B on the first display unit 24 and the second display unit 26 may not be able to be implemented, an alternative plan to the top plan (e.g., the fifth plan P5) is displayed, so that the occupants can know in advance that there is a possibility that the fifth plan P5 will be scheduled to be implemented instead of the first plan.

[0155] In addition, an alternative plan (e.g., the fifth plan P5) is displayed in a different color (e.g., light gray) from the other plans, allowing the occupants to intuitively understand that it is not a plan that is scheduled to be implemented, but a plan that may be implemented.

[0156] In particular, since the alternative plans (for example, the fifth plan P5) are displayed in a grayed-out state, it is easy for the crew to intuitively understand that these are plans that are not currently scheduled to be implemented.

[0157] Furthermore, in this embodiment, if the operation of the top plan (e.g., the first plan P1) has not started when the vehicle 12 reaches the planned execution location of the top plan, it is determined that the operation of the top plan is unlikely to be executed, and an alternative plan is displayed.

[0158] In other words, the alternative plan is not displayed until it is time to implement the alternative plan, but is displayed at a point when there is a high probability that the alternative plan will be implemented (when the top plan is determined to be unfeasible), in other words, from before the location where the alternative plan is scheduled to be implemented. Therefore, by visually checking the alternative plan, the occupants can grasp the possibility of implementing the alternative plan.

[0159] In addition, since the planned implementation location of the alternative plan is set farther away than the planned implementation location of the top plan, even if operation does not start at the planned implementation location of the top plan, it is possible to ensure that operation of the top plan will start up to the planned implementation location of the alternative plan, rather than immediately switching to implementation of the alternative plan.

[0160] Furthermore, since the first display unit 24 is disposed at the upper part in front of the occupant in the driver's seat on the instrument panel 14, and the second display unit 26 is disposed in front of the occupant in the driver's seat on the windshield glass 18, the occupant in the driver's seat can therefore visually confirm the plan updates displayed in the specific display areas 24B, 26B of the first display unit 24 and the second display unit 26 without moving their eyes much. In other words, the occupant in the driver's seat can easily visually confirm the plan updates.

[0161] Furthermore, since the vehicle 12 has such a vehicle display device 10, the occupants can understand that there is a possibility that the top plan will become impossible to implement and that an alternative plan will be scheduled for implementation. In other words, the occupants can understand in advance that they will have to implement the alternative plan through manual driving instead of automatic driving, and can respond calmly when the alternative plan is to be implemented.

[0162] (others)

[0163] Although the vehicular display device and the display processing method according to the embodiment have been described above, it is needless to say that the present invention can be embodied in various forms without departing from the gist of the present invention. For example, in the above embodiment, the first display unit 24 is provided in front of the driver's seat in the instrument panel 14, and the second display unit 26 is a projection surface projected by the head-up display device 44, but this is not limiting. That is, the first display unit may be a center display provided in the center of the instrument panel 14 in the vehicle width direction. Also, the second display unit may be provided on the instrument panel 14 on the vehicle front side of the steering wheel 16.

[0164] In the embodiment, the top plan is enlarged and displayed in the specific display areas 24B, 26B of the first display unit 24 and the second display unit 26 by the function of the highlighting unit 60, but this is not essential. That is, in the specific display areas 24B, 26B of the first display unit 24 and the second display unit 26, all of the plans may be displayed at the same size.

[0165] Furthermore, in this embodiment, when the vehicle 12 reaches the planned implementation location of the first plan P1 and the operation of the first plan P1 is not started, an alternative plan is displayed in the specific display areas 24B, 26B, but this is not limited to this.

[0166] For example, control may be performed based on time instead of the scheduled execution position. In other words, the control is not limited to the position of the vehicle 12 as long as the scheduled execution timing of the operation of the first plan P1 is specified.

[0167] Furthermore, if the ECU 28 or the like detects the possibility that the operation of the top plan (e.g., the first plan P1) cannot be carried out before the scheduled execution timing of the top plan, for example, traffic congestion information or accident information, an alternative plan (e.g., the fifth plan P5) may be displayed before the scheduled execution timing (scheduled execution location).

[0168] Furthermore, the specific display areas 24B and 26B may be configured to always display an alternative plan to the top plan.

[0169] In the embodiment, an alternative plan is displayed for the top plan, but the present invention is not limited to this. For example, an alternative plan may be displayed for the second plan (e.g., the second plan P2) following the top plan. In other words, when congestion at the merging point is detected from traffic congestion information, etc., an alternative plan may be displayed for the second plan (not the top plan) which is a merging operation.

[0170] Furthermore, in the embodiment, the alternative plan is displayed in gray in the specific display areas 24B and 26B, and when the implementation schedule is confirmed, the alternative plan is displayed in the same manner as the other plans, but this is not limited to this. When there is a possibility of substitution, the alternative plan may be displayed differently from the other plans (for example, in a different color).

[0171] In addition, in an embodiment, when adding an alternative plan to the specific display area 24B, 26B, it may be displayed outside the specific display area 24B, 26B in each display area 24A, 26A, and then moved from the outside to the inside of the specific display area 24B, 26B (fade-in processing).

[0172] Similarly, when erasing the alternative plan or the top plan from the specific display areas 24B, 26B, it may be erased (fade out process) after moving it from the inside to the outside of the specific display areas 24B, 26B in each display area 24A, 26A.

[0173] Furthermore, in the embodiment, the planned implementation distance of the alternative plan is displayed in the same way as other plans, but since it may be difficult to see the distance when the alternative plan is displayed in gray, it is also possible to consider a configuration in which the planned implementation timing of the alternative plan is displayed using a progress bar or the like.

[0174] Furthermore, in the above embodiment, three pieces of information, namely, the distance to the operation of the vehicle 12, the planned travel route of the vehicle, and the type of driving, are displayed as a plan, but the present invention is not limited to this. For example, information such as the speed limit may be displayed, but it is preferable to display only the above three pieces of information in terms of making the display easier to see. Furthermore, the display of the planned travel route is not limited to the schematic diagrams shown in Figs. 4 to 7, and may be displayed using other icons, etc.

[0175] In the above embodiment, the second display instruction unit 58 displays the two most recent plans on the second display unit 26, but is not limited to this. For example, the second display instruction unit 58 may display the three or more most recent plans on the second display unit 26.

[0176] Furthermore, in the above embodiment, multiple plans are displayed from bottom to top in the order of scheduled execution in the specific display areas 24B, 26B of the first display unit 24 and the second display unit 26, but the direction is not limited to this. For example, multiple plans may be displayed from top to bottom in the order of scheduled execution in the specific display areas 24B, 26B of the first display unit 24 and the second display unit 26.

[0177] Furthermore, in the above embodiment, a plurality of plans are displayed in each of the display areas 24A, 26A of the first display unit 24 and the second display unit 26, but the second display unit 26 may be configured to display only the most recent top plan.

[0178] Please note that the road conditions, plan types, distances, etc. displayed on the screen are described for convenience of explanation only and may not match the actual road conditions.

[0179] In addition, the display process that the CPU 30 executes by reading the software (program) in the above embodiment may be executed by various processors other than the CPU 30. In this case, examples of the processor include a PLD (Programmable Logic Device) such as an FPGA (Field-Programmable Gate Array) whose circuit configuration can be changed after manufacture, and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit configuration designed exclusively for executing a specific process. The display process may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types (for example, a plurality of FPGAs, and a combination of a CPU and an FPGA). The hardware structure of these various processors is, more specifically, an electric circuit that combines circuit elements such as semiconductor elements.

[0180] Furthermore, in the above embodiment, various data are stored in the storage 36, but the present invention is not limited to this. For example, a recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), or a USB (Universal Serial Bus) memory may be used as the storage unit. In this case, various programs and data are stored in these recording media. [Explanation of symbols]
