Description

Technical Field

[0001] This disclosure relates to display devices for vehicles, vehicles, display processing methods, and non-transitory storage media. Background Technology

[0002] For example, Japanese Patent Application Publication No. 2021-088222 discloses a vehicle display device that displays auxiliary behaviors of driving operations (lane changing, lane merging, lane splitting, etc.) on a display or a head-up display (hereinafter referred to as "HUD") on a path that guides the vehicle to its destination.

[0003] In this display device, the display process involves displaying multiple auxiliary actions in a stacked manner from bottom to top, starting from the position closest to the operating position (distance). The bottommost auxiliary action that has ended is eliminated, and a new auxiliary action is added and displayed on top.

[0004] However, in the display device disclosed in Japanese Patent Application Publication No. 2021-088222, there is a concern that when the same auxiliary action (such as changing lanes to the right) is performed consecutively, the occupant may have difficulty perceiving that the display has been updated. In other words, there is room for improvement in enabling the occupant to reliably perceive when the display has been updated. Summary of the Invention

[0005] This disclosure provides a vehicle display device, vehicle, display processing method, and program that enable occupants to reliably monitor the updated display.

[0006] The vehicle display device according to the first method includes: a display unit installed inside the vehicle compartment, having a display area capable of displaying images; and a control unit that arranges multiple plans to be implemented by the vehicle in a predetermined implementation order in the display area, and when a specified condition is met for the first plan to be implemented among the multiple plans, i.e., the head plan, the head plan is eliminated in the display area by fading out.

[0007] In this vehicle display device, a display unit is installed inside the passenger compartment. The display area of ​​this unit is used by a control unit to display multiple plans scheduled to be implemented by the vehicle in a predetermined execution order. When the conditions for the first scheduled plan (the "head plan") displayed in the display area are met, the control unit fades the head plan out of the display area. Thus, the occupants can clearly understand that the conditions for the head plan have been met.

[0008] In particular, when the same (type) of plans are displayed continuously in the display area, if only the first plan is eliminated and the display is updated to show the new plan, there is a concern that the passengers may not notice that the plan display on the display area has been updated. However, since the plan is eliminated by fading, the passengers can reliably know that the plan display in the display area has been updated.

[0009] The "fading process" includes either the image display process that maintains the position of the item displayed in the display area unchanged (without moving the item) and gradually reduces the display density of the item to eliminate it, or the image display process that moves the item within the display area and then eliminates it.

[0010] The vehicle display device involved in the second method is based on the vehicle display device involved in the first method. When the control unit eliminates the head plan, it moves the plan that is displayed together with the head plan in the display area to the position where the head plan is displayed in the display area.

[0011] In this vehicle display device, when the head plan is eliminated in the display area of ​​a display unit that displays multiple plans in a predetermined implementation sequence, the plan that was displayed together with the head plan in the display area is moved to the position where the head plan was displayed in the display area, so that the occupant can clearly understand the update of the plan display and the next planned implementation plan.

[0012] The vehicle display device involved in the third method is completed based on the vehicle display device involved in the first or second method, and the control unit adds a plan that is different from the above multiple plans to the display area, that is, an additional plan.

[0013] In this vehicle display device, the control unit eliminates the initial plan in the display area and displays an additional plan, which is different from the multiple plans currently displayed in the display area. That is, the initial plan among the multiple plans currently displayed in the display area is eliminated, and an additional plan, different from the multiple plans currently displayed, is added to the display area. Thus, by visually confirming the display area of ​​the display device, the occupant can grasp a constant number of multiple planned implementations.

[0014] The vehicle display device involved in the fourth method is based on the vehicle display device involved in any of the methods 1 to 3. The control unit displays the road image of the vehicle in motion in the display area at a position different from the multiple plans. When the conditions specified for the head plan are met, the head plan is moved to the road image in the display area and then eliminated.

[0015] In this vehicle display device, when the specified conditions of the head plan are met, the control unit causes the head plan to be eliminated after it is moved to a road image of the vehicle being driven, which is displayed at a position different from multiple plans in the display area.

[0016] Therefore, since the head plan is moved on the display area of ​​the display device to the road image that is easy for the occupant to focus on, the occupant can more reliably grasp the elimination of the head plan (the update of the plan display in a specific display area).

[0017] The vehicle display device involved in the fifth method is completed based on the vehicle display device involved in any of the methods 1 to 4, and the aforementioned conditions of the head plan are met when the operation of the head plan is started.

[0018] In this vehicle display device, when a head-planning action is initiated in the vehicle, the control unit determines that the prescribed conditions for the head-planning action have been met and eliminates the head-planning action through a fading process.

[0019] Thus, the crew can reliably control the actions planned for the head to begin.

[0020] The vehicle display device according to the sixth method includes: a display unit provided in the passenger compartment and having a display area capable of displaying images; and a control unit that arranges and displays multiple plans to be implemented by the vehicle in a predetermined implementation order in the display area, and after the last plan to be implemented among the multiple plans, i.e. the tail plan, is eliminated in the display area by fading out, a plan different from the multiple plans, i.e. an additional plan, is inserted between the multiple plans to arrange and display them in a predetermined implementation order.

[0021] In this vehicle display device, after the control unit fades out the last scheduled plan (the last plan) among multiple plans displayed in the display area, it inserts a plan different from the multiple plans (an additional plan) between the multiple plans displayed in the display area to arrange them in a predetermined execution order. For example, even if an additional plan is subsequently generated, the additional plan can be inserted between the multiple plans displayed in the display area, and the multiple plans can be displayed in the display area in a predetermined execution order.

[0022] "Insert between multiple plans" includes inserting at the very end of multiple plans displayed in the display area.

[0023] The vehicle display device involved in the seventh method is based on the vehicle display device involved in the third or sixth method. When the control unit displays the additional plan in the display area, it displays the additional plan in the display area through a fading process.

[0024] The vehicle display device eliminates the head or tail plan from the multiple plans displayed in the display area of ​​the display section, and displays the plan that is different from the multiple plans (additional plan) in the display area of ​​the display device through a fading process.

[0025] As a result, the crew can clearly understand the additional plan and where it is inserted (the scheduled execution order).

[0026] The "gradual appearance processing" includes: image display processing that gradually increases the density of the plan at the display position within the display area to display the plan, and image display processing that moves the plan from other positions to the display position within the display area to display the plan.

[0027] The vehicle display device involved in the eighth method is based on the vehicle display device involved in any of the methods from the first to the seventh method, and the control unit causes the above-mentioned plan to be highlighted before it is removed from the above-mentioned display area.

[0028] In this vehicle display device, the control unit emphasizes the plan (head plan or tail plan) before it is removed from the display area of ​​the display unit.

[0029] As a result, the occupants can more reliably recognize that either the head plan or the tail plan has been eliminated (the plan display has been updated).

[0030] The vehicle display device involved in the ninth embodiment is based on the vehicle display device involved in any of the embodiments from the first to the eighth embodiment, and the aforementioned display unit is installed in the dashboard in front of the driver's seat of the vehicle.

[0031] In this vehicle display device, since the display unit is located in front of the driver's seat in the dashboard, the occupant can confirm the plan according to the predetermined sequence of actions without significantly moving their eyes.

[0032] The vehicle display device involved in the 10th embodiment is based on the vehicle display device involved in any of the 1st to 8th embodiments, wherein the display unit is a projection surface projected by a head-up display device.

[0033] In this vehicle display device, the display section is a projection surface projected by a head-up display device, which displays multiple plans on the projection surface above the vehicle in a predetermined sequence. Thus, the driver and passengers can view the multiple plans in the predetermined sequence without significantly shifting their gaze.

[0034] The vehicle involved in Method 11 is equipped with the vehicle display device of Methods 1 to 10.

[0035] Since the vehicle is equipped with a vehicle display device as described in any of the methods 1 to 10, it is easy to grasp the plan to be implemented by the vehicle and to reliably grasp the update of the plan display in the vehicle display device.

[0036] The display processing method involved in the 12th method is a display processing method that arranges multiple plans to be implemented by the vehicle in a predetermined implementation order in a display area capable of displaying images in a display unit provided in the carriage. The method includes the following steps: when a specified condition is met for the first plan to be implemented among the multiple plans, namely the head plan, the head plan is eliminated in the display area by fading out.

[0037] This display processing method achieves the same effect as the first method.

[0038] The procedure involved in the 13th method is a procedure that arranges multiple plans to be implemented by the vehicle in a predetermined implementation order in a display area capable of displaying images in a display unit provided in the carriage. The computer performs a process including the following steps: when a specified condition is met for the first of the multiple plans to be implemented, namely the head plan, the head plan is eliminated in the display area by fading out.

[0039] By having the computer execute the program, the same effect as the first method can be achieved.

[0040] As explained above, with the vehicle display device involved in methods 1, 2, 5, 7, and 8, the occupant can reliably know that the planned display has been updated.

[0041] According to the vehicle display device involved in the third and sixth methods, a certain number of multiple plans are always displayed on the display section.

[0042] According to the vehicle display device involved in Method 4, the occupant can reliably identify the implemented plan (driving assistance control).

[0043] According to the vehicle display device involved in the 9th and 10th methods, the occupant in the driver's seat can confirm the plan arranged in the predetermined implementation sequence without significantly moving their eyes.

[0044] According to the vehicle involved in Method 11, the occupants can reliably know that the display for the plan has been updated.

[0045] According to the display processing method involved in Method 12, the occupants can reliably know that the planned display has been updated.

[0046] According to the procedures involved in Method 13, the occupants can reliably know that the display of the plan has been updated. Attached Figure Description

[0078] [First Implementation]

[0079] The vehicle 12, which utilizes the vehicle display device 10 according to the first embodiment, will be described with reference to the accompanying drawings. As an example, the vehicle 12 of this embodiment is configured to switch between automatic and manual driving. Figure 1 As shown, an instrument panel 14 is provided at the front of the passenger compartment of vehicle 12.

[0080] The instrument panel 14 extends along the width of the vehicle, and a steering wheel 16 is provided on the right side of the instrument panel 14. That is, in this embodiment, as an example, it is a right-hand drive vehicle with the steering wheel 16 provided on the right side, and the driver's seat is located on the right side of the vehicle.

[0081] A windshield 18 is provided at the front end of the instrument panel 14. The windshield 18 extends along the vertical direction and the width direction of the vehicle to divide the interior of the passenger compartment from the exterior of the passenger compartment.

[0082] The right end of the windshield 18 is fixed to the right front pillar 20 of the vehicle. The front pillar 20 extends vertically along the vehicle, and the windshield 18 is fixed to its inner end in the vehicle width direction. Additionally, the front end of the front side glass 22 is fixed to the outer end of the front pillar 20 in the vehicle width direction. Furthermore, the left end of the windshield 18 is fixed to the left front pillar (not shown).

[0083] Here, a first display unit 24 is provided in the instrument panel 14. The first display unit 24 is located in front of the driver's seat in the instrument panel 14, and is positioned so that it enters the driver's field of vision when the driver's gaze is directed forward.

[0084] A second display unit 26 is provided on the windshield 18. The second display unit 26 is located on the vehicle-top side of the first display unit 24 and is connected to the head-up display device 44 (see reference). Figure 2 The projection surface is formed by the projection. Specifically, a head-up display device 44 is provided on the side of the vehicle that is closer to the front of the instrument panel 14, and the head-up display device 44 is configured to project images onto the second display section 26 of the windshield 18.

[0085] (Hardware structure of vehicle display device 10)

[0086] The vehicle 12 is equipped with an ECU (Electronic Control Unit) 28 as a control unit. Figure 2 This is a block diagram showing the hardware structure of the vehicle display device 10. (As shown...) Figure 2 As shown, the ECU28 of the vehicle display device 10 is configured to include a CPU (Central Processing Unit) 30, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 34, a storage device 36, a communication interface 38, and an input / output interface 40. All components are connected via a bus 42 to enable communication with each other.

[0087] CPU 30 is the central processing unit, which executes various programs and controls various components. Specifically, as a processor, CPU 30 reads programs from ROM 32 (which serves as memory) or memory 36 (which serves as storage), and uses RAM 34 as its working area to execute the programs. CPU 30 performs control and various arithmetic operations on the aforementioned components based on the programs stored in ROM 32 or memory 36.

[0088] ROM 32 stores various programs and data. RAM 34 serves as a working area to temporarily store programs or data. Storage 36 is composed of HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various programs, including the operating system, and various data. In this embodiment, ROM 32 or storage 36 stores programs and various data used for display processing.

[0089] Communication interface 38 is an interface for the vehicle display device 10 to communicate with a server and other devices not shown, such as Ethernet (registered trademark), LTE, FDDI, Wi-Fi (registered trademark) and other standards.

[0090] A head-up display device 44 for projecting images to 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 is configured to include a steering actuator, an acceleration actuator, and a braking actuator. The steering actuator controls the steering of the vehicle 12. The acceleration actuator accelerates the vehicle 12. The braking actuator decelerates the vehicle 12 by controlling the brakes. Furthermore, sensors (not shown) and a GPS device for enabling the vehicle 12 to drive automatically are connected to the input / output interface 40.

[0091] (Functional structure of vehicle display device 10)

[0092] The vehicle display device 10 uses the aforementioned hardware resources to implement various functions. (Refer to...) Figure 3 The functional structure of the vehicle display device 10 is explained.

[0093] like Figure 3 As shown, the vehicle display device 10 is configured with a functional structure including a communication unit 50, an operation plan setting unit 52, an automatic driving control unit 54, a first display instruction unit 56, a second display instruction unit 58, an emphasis display unit 60, a first determination unit 62, and a second determination unit 64. Each functional structure is implemented by the CPU 30 reading and executing a program stored in the ROM 32 or the memory 36.

[0094] The communication unit 50 transmits and receives data with external servers and other devices via the communication interface 38. For example, it transmits and receives map data and traffic condition data stored on the server. In addition, the communication unit 50 can be configured to conduct vehicle-to-vehicle communication with surrounding vehicles.

[0095] The operation plan setting unit 52 sets the operation plan for the vehicle 12. Specifically, the operation plan from the current location to the destination is set by having the occupants input the destination.

[0096] The automatic driving control unit 54 considers location information and environmental information surrounding the vehicle 12 to enable the vehicle 12 to drive automatically according to a set operating plan. Specifically, the automatic driving of the vehicle 12 is achieved by controlling the actuator 46.

[0097] The first display instruction unit 56 displays the vehicle 12's schedule on the first display unit 24 based on the operation plan set by the operation plan setting unit 52. (See reference...) Figure 4 B Figure 5 B and Figure 6 B will explain the function of the first display indicator unit 56.

[0098] like Figure 4 As shown in Figure B, the set speed VA for cruise control and the current vehicle speed VB of the vehicle 12 are displayed in the upper part of the display area of ​​the first display unit 24. The set speed VA and the vehicle speed VB are displayed on the left side of the display area 24A of the first display unit 24 in the vehicle width direction. The set speed VA is displayed smaller in the lower layer; here, as an example, it is set to 120 km / h. The current vehicle speed VB is displayed in the upper layer as 58 km / h. Therefore, the vehicle 12 is configured to travel at a speed of up to 120 km / h while maintaining a certain distance from the vehicle in front.

[0099] On the left side of display area 24A in 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. By observing image V1, it can be seen that the vehicle is traveling in the middle lane of the three-lane road image R. Furthermore, images V2 and V3 are displayed based on information detected by a type of sensor (not shown) mounted on vehicle 12. Moreover, by observing images V2 and V3, it can be seen that the vehicle is traveling to the right front of the vehicle and in front of the vehicle. The vehicle's position can be detected by a GPS device mounted on vehicle 12. Additionally, sensors such as stereo cameras, ultrasonic sensors, millimeter-wave radar, and lidar can be used in combination as sensors for detecting surrounding vehicles. Furthermore, the system can be configured to determine the position of both the vehicle and surrounding vehicles through vehicle-to-vehicle communication.

[0100] A specific display area 24B is provided on the right side of the display area 24A of the first display unit 24, where the first display instruction unit 56 displays the plans for displaying the vehicle 12. Multiple plans scheduled for implementation are displayed within this specific display area 24B. In this embodiment, as an example, three plans are displayed sequentially from bottom to top: Plan 1, Plan 2, and Plan 3. Each plan displays three pieces of information: the distance from the current position to the predetermined implementation position of the action, the predetermined travel route, and the driving type. The driving type refers to whether the action is performed manually or automatically by the driver. In this embodiment, as an example, only the three most recent plans are displayed, but plans after these three are not shown; however, this is not a limitation. For example, the first display unit 24 may display four or more plans. Furthermore, the number of plans displayed on the first display unit 24 can be arbitrarily set (but can be multiple).

[0101] The following is a detailed explanation of Plan 1 (P1), Plan 2 (P2), and Plan 3 (P3).

[0102] like Figure 4 As shown in Figure B, "100m" is displayed to the left of Plan 1 P1, indicating that the action is performed approximately 100m forward from the current position. Additionally, a lane change from the left lane to the right lane is schematically shown in the center of Plan 1 P1, indicating the planned driving path. Furthermore, "Assist" is displayed to the right of Plan 1 P1, indicating that the action is performed (implemented) through automatic driving (driver assistance control).

[0103] Plan 1 (P1) is shown in a slightly larger size than Plan 2 (P2) and Plan 3 (P3) described later. Furthermore, Plan 1 (P1) is equivalent to the "top plan".

[0104] On the other hand, Plan 2 is displayed above Plan 1 P1. To the left of Plan 2 P2 is "200m", indicating an action to be performed approximately 200m forward from the current position. Furthermore, in the center of Plan 2 P2, a schematic diagram shows the path for merging from the left-hand side lane to the main lane, indicating the predetermined driving route. To the right of Plan 2 P2 is "Manual", indicating an action performed manually. That is, a temporary handover from automatic to manual driving occurs before traveling 200m. In this embodiment, as an example, the configuration is such that the occupant only performs the merging action and switches to automatic driving after the lane change.

[0105] Above Plan 2 (P2) is Plan 3 (P3). To the left of Plan 3 (P3) is displayed "800m," indicating an action to be performed approximately 800m forward from the current position. Additionally, in the center of Plan 3 (P3) is a schematic diagram showing a lane change from the left lane to the right lane, indicating the planned driving path. To the right of Plan 3 (P3) is displayed "Assist," indicating an action performed via automatic driving (driver assistance control).

[0106] Among these, the situation where manual driving plans are inserted into the autonomous driving operation plan is as follows: for example, in situations where it is known in advance that there are often congested merging points and that it is difficult to merge by autonomous driving; or in situations where traffic congestion occurs due to accidents and it is believed that lane changes are difficult to achieve by autonomous driving.

[0107] Figure 5 B shows vehicle 12 from Figure 4 The image displayed on the first display unit 24 shows the image after the vehicle has traveled approximately 100 meters in state B. Figure 5 As shown in B, the display to the left of Plan P1 is changed to "0m", and the display to the left of Plan P2 is changed to "100m". In addition, the display to the left of Plan P3 is changed to "700m".

[0108] in addition, Figure 5 B means Figure 4 The diagram shown in Figure B illustrates one of the animation processes in Plan P1, namely, the fade-out process (the image display process that gradually reduces the display density).

[0109] That is, in Figure 5 In B, the first plan P1 becomes a specific display area 24B in display area 24A from Figure 4 State B reduces the display concentration (this state is shown by indicating the frame representing Plan P1 with a dashed line). Other display content is the same as... Figure 4 B is the same.

[0110] Figure 6 B indicates that... Figure 5 After the fade-out process of Plan P1 shown in Figure B ends (P1 is eliminated), Plans P2 and P3 are displayed in a specific display area 24B as if they have each slid (moved) down one layer and then faded in at the position of the third layer. This is a diagram showing the state of Plan P4 during the process.

[0111] Right now, Figure 6B shows the process (intermediate state) of gradually increasing the display density of the fourth plan P4 at the position of the third layer within a specific display area 24B (this state is shown by showing the frame representing the fourth plan P4 with a dashed line).

[0112] Such as Figure 6 As shown in Figure B, "1.5km" is displayed to the left of Plan 4 P4, indicating that the action is being performed approximately 1.5km forward from the current position. Additionally, a schematic diagram in the center of Plan 4 P4 shows the path for merging from the right-hand side lane into the main lane, indicating the planned driving route. Furthermore, "Assist" is displayed to the right of Plan 4 P4, indicating that the action is being performed using automatic driving (driver assistance control).

[0113] Figure 7 B is a diagram representing the state where the gradual appearance process of Plan P4 is completed.

[0114] like Figure 7 As shown in Figure B, in a specific display area 24B within display area 24A, the display density of plan P4 (4th plan P4) is increased to the display density of other plans (2nd plan P2, 3rd plan P3), and plan P4 is displayed above plan P3 in specific display area 24B. Other display content is... Figure 6 B is the same.

[0115] Next, the second display indicator unit 58 will be described.

[0116] like Figure 3 As shown, the vehicle display device 10 includes a second display instruction unit 58 as a functional structure. The second display instruction unit 58 is configured to display the two earliest planned implementation plans that are displayed by the first display instruction unit 56 on the first display unit 24, which are displayed by the first display instruction unit 56 on the second display unit 26.

[0117] The emphasis display unit 60 has the function of emphasizing (enlarging) the earliest scheduled plan (hereinafter referred to as the "head plan") when multiple plans are displayed in specific display areas 24B and 26B of the first display unit 24 and the second display unit 26, respectively.

[0118] By emphasizing the function of the display unit 60, in a specific display area 24B of the first display unit 24, such as Figure 4 As shown in B, Plan P1, the first plan of the head plan (refer to...) Figure 4 B) or Plan 2 P2 (refer to) Figure 7 B) Displayed at a slightly larger scale than other plans. For example, a magnification of about 110%.

[0119] On the other hand, when the second display unit 26 displays multiple plans, the emphasis display unit 60 emphasizes the most recent plan and displays it on the second display unit 26, making it more prominent than other plans.

[0120] Reference Figure 4 A~ Figure 7 A will explain the functions of the second display indicator 58 and the emphasis display 60. Regarding the image displayed on the second display unit 26, portions substantially the same as those displayed on the first display unit 24 are labeled with the same reference numerals, and detailed descriptions are omitted. Furthermore, portions of the image displayed on the second display unit 26 that are substantially the same as those on the first display unit 24 display content synchronized with the display on the first display unit 24.

[0121] like Figure 4 As shown in Figure A, the lower part of the display area 26A of the second display unit 26 displays the cruise control set speed VA and the current vehicle speed VB. The set speed VA and vehicle speed VB are displayed on the left side of the display area 26A in the vehicle width direction. The set speed VA is displayed on the right side; here, as an example, it is set to 120 km / h. The current vehicle speed is displayed on the left side as 58 km / h. Therefore, the vehicle 12 is set to travel at a speed of up to 120 km / h while maintaining a certain distance from the vehicle in front. The display of the set speed and vehicle speed is synchronized with the content of the first display unit 24.

[0122] On the right side of the display area 26A of the second display unit 26, a specific display area 26B is provided for the plan of vehicle 12 displayed by the second display indicator unit 58. Multiple plans scheduled to be implemented (the most recent first plan P1 and the next scheduled second plan P2) are displayed in the specific display area 26B. The most recent plan, the first plan P1, is displayed below. Figure 4 As shown in Figure A, Plan P1 is enlarged compared to Plan P2 (Plan 2). The distance of 100m from Plan P1 is recorded at the bottom. Above this distance of 100m, a schematic diagram of lane change from the left lane to the right lane is shown. On the right side of this schematic diagram, "Assist" indicating that the system is in automatic driving mode is displayed.

[0123] Additionally, in the display area 26A of the second display unit 26, the second plan P2 is displayed above the first plan P1.

[0124] Figure 5 A indicates that vehicle 12 is from Figure 4 The diagram showing the state of A having traveled to a position of 100m is a diagram representing the state during the fading process of the first plan P1 in a specific display area 26B of display area 26A.

[0125] Figure 6 A indicates that in plan P1 from Figure 5 After state A is eliminated from the specific display area 26B of the display area 26A of the second display unit 26, the second plan P2 moves downward and is enlarged for display, and the state of the process of the added third plan P3 is gradually displayed in the specific display area 26B of the display area 26A.

[0126] Figure 7 A represents the gradual appearance process of Plan P3 from... Figure 6 The diagram shows the state where state A is completed, and in the specific display area 26B, plan P3 is displayed above plan P2.

[0127] Next, the function of the first determination unit 62 will be explained. As described above, the display of the plan in specific display areas 24B and 26B is updated by the first display indicator unit 56 and the second display indicator unit 58. This update begins when the head plan operation has started. The first determination unit 62 determines whether the head plan operation has started.

[0128] Specifically, the first determination unit 62 has the function of detecting whether an action has started for each type of planned action (lane change, lane merging, lane splitting, etc.) based on whether a drive signal for the actuator that is first activated at the start of the action is detected. For example, if the planned action is a lane change to the right lane, the planned action is determined to have started by detecting a flashing drive signal for the direction indicator on the right side of the vehicle 12.

[0129] Next, the function of the second determination unit 64 will be explained. It has the function of determining whether there is a plan to be added to the display when the display of the plan in the specific display areas 24B and 26B is updated.

[0130] Specifically, the determination is made based on whether there is a plan in the operation plan (list of plans) created by the operation plan setting unit 52 that is not displayed in specific display areas 24B and 26B of the first display unit 24 and the second display unit 26.

[0131] In cases where the number of plans displayed in specific display area 24B and specific display area 26B differs as in this embodiment, the second determination unit 64 first determines the first display area 24 (specific display area 24B) with the larger number of displays. This is because, in cases where a definitive determination is made (there are undisplayed (additional) plans), additional plans also exist for the second display area 26 (specific display area 26B).

[0132] On the other hand, in the case of a negative determination, the second determination unit 64 determines whether there are multiple plans displayed in the specific display area 24B, and in the case of a positive determination, determines that there is an additional plan in the second display unit 26.

[0133] (effect)

[0134] Next, the function of this embodiment will be explained.

[0135] (Display processing)

[0136] use Figure 8 as well as Figure 9 The flowchart shown illustrates an example of the display processing for displaying the schedule of vehicle 12 based on the operation plan. This display processing is implemented by the CPU 30 reading the display program from ROM 32 or memory 36, expanding it in RAM 34, and then executing it.

[0137] like Figure 8 As shown, in step S102, the CPU 30 determines whether a destination has been set. The destination can be directly input to the vehicle 12 by the passenger, or indirectly input to the vehicle 12 via a mobile terminal or other means.

[0138] If it is determined in step S102 that a destination has been set, CPU 30 proceeds to step S104. Conversely, if it is determined in step S102 that no destination has been set, CPU 30 terminates the display process.

[0139] In step S104, CPU 30 sets the operation plan for vehicle 12. Specifically, CPU 30 sets the operation plan from the current location to the destination using the function of the operation plan setting unit 52. During operation plan setting, information related to traffic conditions and accidents can be obtained and reflected. Furthermore, the operation plan can be set to enable more automated driving based on pre-input passenger preferences.

[0140] In step S106, CPU 30 causes the first display unit 24 and the second display unit 26 to display the plan. Specifically, based on the running plan, CPU 30 causes the first display unit 24 and the second display unit 26 to display the plan of vehicle 12 through the functions of the first display instruction unit 56 and the second display instruction unit 58, respectively.

[0141] Here, as an example, such as Figure 4 As shown in Figure B, the CPU 30 causes a specific display area 24B, set to the right of the display area 24A of the first display unit 24, to display three plans: Plan P1, Plan P2, and Plan P3. Similarly, as... Figure 4As shown in Figure A, the CPU 30 displays two plans, Plan P1 and Plan P2, in a specific display area 26B set to the right of the display area 26A of the second display unit 26.

[0142] At this time, as Figure 4 As shown in B, by emphasizing the function of the display unit 60, the CPU 30 slightly enlarges the display of the first plan P1, which is the head plan, in a specific display area 24B of the first display unit 24 to display the other plans (the second plan P2 and the third plan P3).

[0143] Similarly, as Figure 4 As shown in Figure A, the CPU 30, by emphasizing the function of the display unit 60, enlarges the display of the first plan P1, which serves as the head plan, in a specific display area 26B of the second display unit 26 to display the other plans (the second plan P2).

[0144] In step S108, the CPU 30 determines whether the head planning (first plan P1) operation has started using the function of the first determination unit 62. The determination is based on the drive signal to the actuator 46, etc. Figure 4 The operation of the first plan P1 (lane change control (driving assistance control)) is shown in the first display unit 24 shown in B, which is the first plan among the plans P1 to P3. For example, in the case of lane change, the first determination unit 62 detects the flashing drive signal of the direction indicator and determines that lane change control (driving assistance control) as the first plan P1 has been started.

[0145] Furthermore, if the determination in step S108 is negative, the CPU30 will remain in standby mode until a positive determination is made.

[0146] If the determination in step S108 is positive, such as Figure 9 As shown, in step S110, the CPU 30 performs fade-out processing on the header plan (first plan P1) displayed on the first display unit 24 and the second display unit 26 by using the functions of the first display indicator 56 and the second display indicator 58.

[0147] Specifically, such as Figure 5 As shown in B, in a specific display area 24B of the display area 24A of the first display unit 24, the display density of the first plan P1, which has started to operate, is gradually reduced to eliminate the first plan P1.

[0148] Similarly, as Figure 5 As shown in Figure A, in a specific display area 26B of the display area 26A of the second display unit 26, the display density of the first plan P1, which has started to operate, is gradually reduced to eliminate the first plan P1.

[0149] Next, in step S112, as Figure 6 As shown in Figure B, the CPU 30 uses the function of the first display indicator 56 to control the second plan P2 and the third plan P3 from... Figure 5 The state of B moves downwards (towards the position where the head plan is displayed) within the specific display area 24B. At this time, the function of the display unit 60 is emphasized to slightly enlarge the display of the second plan P2, which has moved to the position of the head plan.

[0150] Similarly, as Figure 6 As shown in Figure A, CPU 30 uses the function of the second display indicator 58 to cause the second plan P2 to start from... Figure 5 The state of A moves downwards. At this time, the function of the display unit 60 is emphasized to enlarge and display the second plan P2, which has moved to the head plan position.

[0151] Furthermore, in step S114, the CPU 30 uses the function of the second determination unit 64 to determine whether there is a plan (additional plan) that is not displayed in a specific display area 24B of the first display unit 24. If the determination is positive, the process proceeds to step S116; if the determination is negative, the process proceeds to step S118.

[0152] In step S116, as Figure 6 B Figure 7 As shown in Figure B, the CPU 30 performs a gradual display process on the earliest planned additional plan, namely the fourth plan P4, which is not currently displayed, through the function of the first display indicator 56. Specifically, in a specific display area 24B of display area 24A, the display density of the fourth plan P4 is gradually increased from a position above the third plan P3 until it reaches the display density of the other plans (the second plan P2 and the third plan P3), so that the fourth plan P4 is displayed above the third plan P3. That is, as shown in Figure B. Figure 7 As shown in B, at the current position of vehicle 12, the three earliest scheduled plans (Plan 2, Plan 3, and Plan 4) are displayed (the plans displayed in the specific display area 24B are updated).

[0153] Similarly, as Figure 6 A, Figure 7 As shown in Figure A, the CPU 30, through the function of the second display indicator 58, gradually increases the display density of the added third plan P3 in a specific display area 26B of the display area 26A, above the second plan P2, until it reaches the display density of the other plan (the second plan P2), so that the third plan P3 is displayed above the second plan P2. That is, as shown in Figure A. Figure 7 As shown in A, at the current position of vehicle 12, the two earliest scheduled plans (Plan 2 P2 and Plan 3 P3) are displayed (the plans displayed in the specific display area 26B are updated).

[0154] Furthermore, if the determination is negative in step S114, in step S118, the CPU30 determines whether multiple plans are displayed in the first display unit (specific display area 24B) by using the function of the second determination unit 64.

[0155] This is because: since the number of plans displayed in the specific display area 26B of the second display unit 26 (2 in this embodiment) is less than the number of plans displayed in the specific display area 24B of the first display unit 24 (3 in this embodiment), even if there are no additional plans for the first display unit 24, as long as there are multiple plans displayed in the first display unit 24, there are additional plans for the second display unit 26.

[0156] Therefore, if the determination is positive in step S118, in step S120, the CPU 30, through the function of the second display indicator 58, performs a gradual display process for the added third plan P3 only on the second display unit 26. Specifically, the display density of the added third plan P3 is gradually increased in a specific display area 26B of the display area 26A, above the second plan P2, until it reaches the display density of the other plan (the second plan P2), so that the third plan P3 is displayed above the second plan P2. That is, as... Figure 7 As shown in A, at the current position of vehicle 12, the two earliest scheduled plans (Plan 2 P2 and Plan 3 P3) are displayed (the plans displayed in the specific display area 26B are updated).

[0157] Furthermore, if the determination is negative in step S118, CPU30 moves to step S122.

[0158] Next, in step S122, the CPU 30 determines whether a predetermined execution plan remains in the first display unit 24 (specific display area 24B). If the determination is positive in step S122, the process returns to step S108 since the display processing of the plan is required.

[0159] If the determination is negative in step S122, the display process ends because there is no plan to display in the specific display areas 24B and 26B of the first display unit 24 and the second display unit 26.

[0160] As described above, in the vehicle display device 10 according to this embodiment, the head plan (e.g., the first plan P1) that has started to operate is faded out in the first display unit 24 and the second display unit 26. Specifically, in a specific display area 24B of the display area 24A of the first display unit 24 and a specific display area 26B of the display area 26A of the second display unit 26, the display density of the head plan (e.g., the first plan P1) is gradually reduced to eliminate the head plan.

[0161] Thus, when the head plan (e.g., the first plan P1) displayed in the specific display areas 24B and 26B is eliminated in the first display unit 24 and the second display unit 26, it is eliminated by fading (the display density of the head plan is gradually reduced in the specific display areas 24B and 26B), so the occupant in the driver's seat can reliably know that the head plan has been eliminated from the first display unit 24 and the second display unit 26.

[0162] Therefore, even if the same (same type) plan (e.g., lane change to the right lane) is continuously displayed in a specific display area 24B of the first display unit 24 or a specific display area 26B of the second display unit 26, it is possible to prevent or suppress the situation where the display of the plan that the occupant cannot understand is updated (the head plan is eliminated).

[0163] Furthermore, when updating the display of the plan in specific display areas 24B and 26B of the first display unit 24 or the second display unit 26, since the remaining plan is moved (slid) downwards (each one layer down) after the head movement plan is moved (eliminated), and the additional plan is added by using a gradual display process (gradually increasing the display density of the additional plan), the occupant can reliably grasp the addition of the plan (updating the display of the plan).

[0164] Furthermore, the first display unit 24 is positioned in the dashboard 14 at the upper front of the driver's seat occupant, and the second display unit 26 is positioned in the windshield 18 in front of the driver's seat occupant. Therefore, the driver's seat occupant can visually confirm updates to the schedule displayed in specific display areas 24B and 26B of the first display unit 24 and the second display unit 26 with minimal eye movement. In other words, the driver's seat occupant can easily visually confirm schedule updates.

[0165] Furthermore, since the vehicle 12 has such a vehicle display device 10, the occupants can easily grasp the planned implementation sequence of the planned actions (lane changes, lane merging, etc.) and can reliably grasp the updates of the plan display.

[0166] (First Change)

[0167] The first modification of the vehicle display device 10A according to this embodiment will be described. Since the difference from the first embodiment lies only in the method of fading the headlights, reference will be made to... Figure 10 This is just one point I'll make.

[0168] In the vehicle display device 10A involved in the first modification, the first plan P1, which is initially faded out in a specific display area 24B of the display area 24A of the first display unit 24 as part of the head plan, is highlighted before the fading out (e.g., flashing process). Figure 10 (The thick lines of the first display section 24 in the middle).

[0169] In the first modified vehicle display device 10, since the first plan P1, which is the head plan, is enlarged and displayed in specific display areas 24B and 26B as in the first embodiment, the emphasis display means an emphasis display in addition to the enlarged display. However, if the first plan P1, which is the head plan, is not enlarged and displayed as in the first embodiment, the emphasis display also includes the enlarged display.

[0170] As a result, the crew can more reliably know when the action of Plan P1 begins (is implemented) and when the display of Plan P1 is eliminated.

[0171] (Second Change)

[0172] The second modification of the vehicle display device in this embodiment will be described. The functional structure of the vehicle display device 10B involved in the second modification is slightly different from that of the vehicle display device 10, and the display processing is different. This difference will be explained.

[0173] Reference Figure 11 Flowchart and Figures 12-15 The display process for adding a plan (hereinafter referred to as "additional plan") when a plan that is different from the plan set in the pre-set operation plan needs to be added is explained.

[0174] First, the functional structure of the vehicle display device 10B will be described. Components with the same functional structure as those in the vehicle display device 10 of the first embodiment will be labeled with the same reference numerals in the accompanying drawings, and detailed descriptions thereof will be omitted.

[0175] like Figure 12As shown, the vehicle display device 10B has a third determination unit 66. The third determination unit 66 has the functions of determining whether there is a new plan (additional plan) generated by the operation plan setting unit 52, and determining whether the additional plan must be inserted and displayed in each specific display area 24B, 26B of the first display unit 24 and the second display unit 26.

[0176] Specifically, if the operation planning setting unit 52 adds (generates) a plan other than the original plan, the third determination unit 66 determines that an additional plan has been generated. Furthermore, in this case, the third determination unit 66 determines whether it is necessary to insert the additional plan into each specific display area 24B or 26B based on whether the predetermined implementation order of the additional plan is lower than or equal to the number of plans displayed in the specific display area 24B of the first display unit 24 (3 in this modification) or the number of plans displayed in the specific display area 26B of the second display unit 26 (2 in this modification).

[0177] (effect)

[0178] The following display processing is performed in the vehicle display device 10B.

[0179] First, in step S202, the CPU 30 determines whether an additional plan has been generated by the operation plan setting unit 52 using the function of the third determination unit 66. Specifically, if the CPU 30 detects a vehicle action (vehicle operation) not in the operation plan using the function of the operation plan setting unit 52, it determines whether an additional plan needs to be added accordingly, and generates the additional plan if necessary. If the generation of such an additional plan is detected, the CPU 30 determines that an additional plan has been generated.

[0180] For example, when in Figure 1 If, due to a sudden deceleration of the vehicle ahead (shown in image V3), the occupants of vehicle 12 manually change lanes to the left (shown in image V1), vehicle 12 needs to perform an additional lane change to the right to return to its original lane. In this situation, an additional plan (lane change to the right lane) is generated.

[0181] If the decision in step S202 is negative, CPU30 ends the processing.

[0182] Next, if the determination is positive in step S202, the CPU 30 determines in step S204 whether the plan (the fifth plan P5) needs to be inserted into the specific display areas 24B and 26B of the first display unit 24 and the second display unit 26, respectively, by using the function of the third determination unit 66.

[0183] This is because, for example, if the additional plan is the fourth or subsequent plan in the planned implementation sequence, then after the head plan (Plan 1 P1) is eliminated, it can be displayed using the usual fading process (as opposed to...). Figure 9 Step S116 of the flowchart (refer to) Figure 6 B) Same).

[0184] For example, in the case where a lane change to the right lane is added because the vehicle manually changed lanes to the left as described above, the lane change to the right lane needs to be carried out at least before merging to the right (Plan 2). Therefore, the planned implementation distance of Plan 5 P5 as an additional plan is set to be 150m closer to the planned implementation distance of Plan 200m.

[0185] CPU30, through the function of the third determination unit 66, determines that it needs to be inserted before the second plan P2 because the predetermined implementation distance of the fifth plan P5, which is an additional plan, is less than the predetermined implementation distance of the second plan P2.

[0186] If the determination in step S204 is negative, CPU30 ends the display process.

[0187] If the determination is positive in step S204, the CPU30 performs a fade-out process in step S206 on the plan that is scheduled to be implemented last (hereinafter referred to as "last plan") that is displayed at the top in each specific display area 24B and 26B of the first display unit 24 and the second display unit 26.

[0188] That is, such as Figure 13 As shown in B, the display density of the third plan P3, which is the tail plan, is gradually reduced and eliminated in a specific display area 24B of the display area 24A of the first display unit 24 by the function of the first display indicator 56.

[0189] Similarly, as Figure 13 As shown in A, the display density of the second plan P2, which is the tail plan, is gradually reduced and eliminated in a specific display area 26B of the display area 26A of the second display unit 26 by the function of the second display indicator 58.

[0190] Next, in step S208, when there is display space above the insertion position of the additional plan in the specific display areas 24B and 26B, the CPU30 performs sliding processing through the functions of the first display indicator 56 and the second display indicator 58.

[0191] Specifically, such as Figure 14As shown in B, in a specific display area 24B of the first display unit 24, the second plan P2, which is displayed above the insertion position of the fifth plan P5, moves upward.

[0192] In addition, such as Figure 14 As shown in A, in the first display unit 26, since there is no space to display other plans above the insertion position of the fifth plan P5 in the specific display area 26B, the sliding process is not performed.

[0193] Next, in step S210, CPU30 performs the gradual appearance process of the fifth plan P5 as an additional plan.

[0194] Specifically, such as Figure 14 As shown in Figure B, by utilizing the function of the first display indicator 56, the display density of the fifth plan P5 is gradually increased in a specific display area 24B within the display area 24A of the first display unit 24, at a position between the first plan P1 and the slid-down second plan P2, until it reaches the display density of the other plans (first plan P1, second plan P2). The result is as follows: Figure 15 As shown in B, in a specific display area 24B, the fifth plan P5 is inserted (displayed) between the first plan P1 and the second plan P2.

[0195] Similarly, as Figure 14 As shown in Figure A, through the function of the second display indicator 58, the display density of the fifth plan P5 is gradually increased in a specific display area 26B of the display area 26A of the second display unit 26, above the first plan P1, and then increased to the display density of other plans (the first plan P1). As a result, as... Figure 15 As shown in A, the fifth plan P5 is inserted (displayed) above the first plan P1 within a specific display area 24B.

[0196] Thus, in the vehicle display device 10 involved in the second modification, when an additional plan is generated due to the vehicle's movement (occupant's operation) and an additional plan (for example, the fifth plan P5) is inserted into a specific display area 24B of the first display unit 24 and a specific display area 26B of the second display unit 26, the tail plan (the third plan P3 and the second plan P2) is eliminated from the specific display areas 24B and 26B respectively by fading out. If necessary, a sliding process is performed (moving the second plan P2 to the top), and the additional plan (the fifth plan P5) is inserted into the specific display areas 24B and 26B by fading out.

[0197] Therefore, the occupants can reliably recognize that the tail plan has been removed from the display and that an additional plan (Plan 5) has been inserted. That is, the driver can reliably recognize that an additional plan has been added.

[0198] In particular, since the additional plan (Plan 5) is inserted into specific display areas 24B and 26B through a fading process, the occupants are able to clearly recognize which position of the multiple displayed plans it has been inserted into.

[0199] Furthermore, the "insertion" of additional plans includes not only inserting additional plans between multiple plans, but also situations such as... Figure 15 As shown in Figure A, the items are inserted at the ends (positions) of multiple schedules arranged and displayed in specific display areas 24B and 26B.

[0200] [Second Implementation]

[0201] The vehicle display device 100 according to the second embodiment will be described. Components that are the same as those in the vehicle display device 10 according to the first embodiment will be labeled with the same reference numerals in the accompanying drawings, and detailed descriptions thereof will be omitted.

[0202] Furthermore, since the only difference between this device and the vehicle display device 10 is the display processing method, please refer to... Figure 16 The flowchart shown and Figure 17 This section will only be explained.

[0203] Since the first half of the display processing in the vehicle display device 100 is exactly the same as the display processing in the vehicle display device 10 (see reference...) Figure 8 Therefore, through Figure 8 The flowchart will be used to illustrate this. Additionally, in Figure 16 In the flowchart, the same step reference numerals are used to mark the same steps as those used in the display processing of the vehicle display device 10, and detailed descriptions are omitted.

[0204] In step S108 (refer to) Figure 8 In the process, if it is determined that the action of the head plan (Plan 1 P1) has begun, then in Figure 16 In step S302, the CPU 30, through the functions of the first display indicator 56 and the second display indicator 58, moves the first plan P1 from specific display areas 24A and 26A of the first display unit 24 and the second display unit 26 to the left (outside) and onto the road image R (refer to...). Figure 17 A, Figure 17 B).

[0205] Next, in step S304, the CPU 30 uses the functions of the first display indicator 56 and the second display indicator 58 to fade out the first plan P1 located on the road image R in the display area 24A of the first display unit 24 and the display area 26A of the second display unit 26, respectively.

[0206] At the same time, the CPU 30 moves (slides) the remaining plans (the second plan P2 and the third plan or the second plan) downward in each specific display area 24B, 26B of the first display unit 24 and the second display unit 26, and if there are additional plans, displays the additional plans (the fourth plan P4 or the third plan P3) on the top layer of the specific display areas 24B, 26B through a fade-in process (steps S112 to S116).

[0207] According to the vehicle display device 100 that performs display processing in this way, since the head plan (first plan P1) that has been started is moved onto the road image R, the occupant can reliably grasp the plan of the action being carried out.

[0208] For example, if the first plan and the next (second) plan to be implemented are of the same type (lane change to the right lane), if the plan display is updated only by removing the first plan from specific display areas 24B and 26B when the action begins, there is a concern that passengers may misunderstand that the plan that has started the action is the next plan.

[0209] However, in the vehicle display device 100, by moving the head plan (first plan P1) that has started the action to the road image R displayed in the display areas 24A and 26A of the first display unit 24 and the second display unit 26, the occupant can reliably grasp which plan is the one that is currently performing the action.

[0210] Furthermore, the vehicle display device 100 has the same function as the vehicle display device 10.

[0211] (other)

[0212] The vehicle display device and display processing method according to the embodiments have been described above, but they can of course be implemented in various ways without departing from the spirit of this disclosure. For example, in the above embodiments, 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 a limitation. That is, the first display unit may also be a central display provided in the center of the instrument panel 14 in the vehicle width direction. Alternatively, the second display unit may be provided on the vehicle front side of the steering wheel 16 in the instrument panel 14.

[0213] Furthermore, in the first embodiment (including the first and second modifications, hereinafter the same) and the second embodiment, the display header is enlarged in each specific display area 24B, 26B of the first display unit 24 and the second display unit 26 to emphasize the function of the display unit 60, but this is not mandatory. That is, multiple complete displays can be displayed at the same size in each specific display area 24B, 26B of the first display unit 24 and the second display unit 26.

[0214] Furthermore, in the first modification of the first embodiment, when the header plan is faded out, it is emphasized by flashing the header plan, but this is not limited to this; other methods can also be used for emphasis. For example, emphasis can be achieved by changing the color and tone. Alternatively, emphasis can be achieved by increasing the brightness of the plan. When multiple complete plans (without enlarging the header plan) are displayed at the same size in each specific display area 24B, 26B of the first display unit 24 and the second display unit 26, the header plan can be emphasized by enlarging the header plan when fading out.

[0215] Furthermore, in the above embodiment, as a plan, three pieces of information are displayed: the distance from the vehicle 12 until its movement, the vehicle's planned travel path, and the driving category. However, this is not a limitation. For example, information such as speed limits may also be displayed, but from the viewpoint of making the display easy to observe, it is preferable to display only the above three pieces of information. Additionally, the display of the planned travel path is not limited to... Figures 4-6 The diagram shown can also be displayed using other icons or similar symbols.

[0216] Furthermore, in the above embodiment, the second display indicator 58 displays the two most recent plans on the second display unit 26, but it is not limited to this. For example, the second display indicator 58 may display three or more most recent plans on the second display unit 26.

[0217] Furthermore, in the above embodiment, multiple plans are displayed from bottom to top in a predetermined implementation order in specific display areas 24B and 26B of the first display unit 24 and the second display unit 26, but this is not limited to that direction. For example, multiple plans may also be displayed from top to bottom in a predetermined implementation order in specific display areas 24B and 26B of the first display unit 24 and the second display unit 26.

[0218] Furthermore, in the above embodiment, multiple plans are displayed in each display area 24A and 26A of the first display unit 24 and the second display unit 26, but the second display unit 26 may be structured to display only the most recent top plan.

[0219] Furthermore, in the above embodiment, planned fading, sliding, and appearing processes are performed in each display area 24A, 26A of the first display unit 24 and the second display unit 26. However, it is also possible to perform the above processes only in either the first display unit 24 or the second display unit 26. In addition, in the first display unit 24 and the second display unit 26, only the planned fading process for the header is necessary, while the sliding process and the appearing process for additional plans can be omitted.

[0220] In a series of embodiments, the fading process is described as an image display process that gradually reduces the display density of a plan within a specific display area 24B, 26B and eliminates it, but it is not limited to this. For example, it could also be a process in which the plan is eliminated after it has moved from within the display areas 24A, 26A to outside the specific display areas 24B, 26B. In this case, the display density of the plan can be gradually reduced during the movement, or the display density can be moved constantly and eliminated after the movement.

[0221] Similarly, the fading-in process, although described as an image display process that gradually increases the display density of a display within specific display areas 24B and 26B, is not limited to this. For example, it could also be a process that moves a display outside specific display areas 24B and 26B towards the interior of specific display areas 24B and 26B within display areas 24A and 26A. In this case, the display density of the display can gradually increase during the movement, or the display density can remain constant during the movement.

[0222] If it is the first implementation method, then as follows Figure 18 As shown in B, when fading out the first plan P1, which is the head plan, it is possible to consider making the first plan P1 disappear after moving it from a specific display area 24B to the right side in display area 24A. Similarly, as Figure 19 As shown in B, when the fourth plan P4, which is an additional plan, is gradually revealed, it is possible to consider eliminating the fourth plan P4 after it is moved from a specific display area 24B to the right side in the display area 24A.

[0223] like Figure 18 A, Figure 19 As shown in A, it can be considered that image display processing is also performed in the second display unit 26 in the same way as in the first display unit 24.

[0224] In the vehicle display devices of the first and second embodiments, the fading process for the head plan begins at the start of the head plan's action, but the start condition for the fading process is not limited to this. For example, the start condition for the fading process can be set to the completion of the head plan's action, or it can be set to the time when the vehicle 12 passes through the predetermined implementation position. The start condition for this fading process is not particularly limited as long as it is a condition related to the head plan. These start conditions are equivalent to "prescribed conditions".

[0225] Furthermore, in the explanatory figures of the first and second embodiments, it is shown that the fading process begins at the predetermined implementation position (0m) of the head plan, but it is not limited to this. For example, if the flashing of the direction indicator begins earlier than the predetermined implementation position of the lane change to the right lane in the first plan P1, then the fading process can simply begin from the flashing start position (flashing start time) of the direction indicator.

[0226] Furthermore, in a series of embodiments, for ease of explanation, it is described that planned fading, sliding, and fading-in processes are performed at different times in the display areas 24A and 26A of the first display unit 24 and the second display unit 26, but these processes may also be performed simultaneously.

[0227] In a series of implementations, for ease of explanation, the fading process is illustrated as planned to be eliminated after moving to the outside of specific display areas 24B, 26B while maintaining a certain concentration, but it can also be eliminated by gradually reducing the concentration while moving.

[0228] Furthermore, the road conditions, types of routes, and distances shown on the screen are merely for illustrative purposes and may not reflect the actual road conditions.

[0229] Furthermore, the display processing implemented by the CPU 30 reading the software (program) in the above embodiment can also be implemented by various processors other than the CPU 30. Examples of processors in this case include FPGAs (Field-Programmable Gate Arrays) and processors with dedicated circuit structures designed for specific processing, such as PLDs (Programmable Logic Devices) and ASICs (Application Specific Integrated Circuits). Additionally, the display processing can be implemented by one of these various processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, or a combination of a CPU and an FPGA). More specifically, the hardware structure of these various processors is a circuit that incorporates circuit elements such as semiconductor components.

[0230] Furthermore, in the above embodiments, the ROM 32 or the memory 36 is configured to store various types of data, but it is not limited to this. For example, non-transitory storage media such as CD (Compact Disk), DVD (Digital Versatile Disk), and USB (Universal Serial Bus) memory can also be used as storage units. In this case, various programs and data are stored on the aforementioned non-transitory storage media.
