[0014] A vehicle 12 to which a vehicle display control device 10 according to an embodiment is applied will be described with reference to the drawings. Note that the vehicle 12 of the present embodiment is configured to be switchable between automatic driving and manual driving, as an example.

[0015] 1, an instrument panel 14 is provided at the front of the passenger compartment of a vehicle 12. The instrument panel 14 extends in the vehicle width direction, and a steering wheel 16 is provided on the right side of the instrument panel 14. That is, in this embodiment, as an example, a right-hand drive vehicle in which the steering wheel 16 is provided on the right side, and the driver's seat is located on the right side of the vehicle.

[0016] A windshield glass 18 is provided at the front end of the instrument panel 14. The windshield glass 18 extends in the vertical direction and the width direction of the vehicle, and separates the inside and outside of the vehicle compartment.

[0017] The right end of the windshield glass 18 is fixed to a front pillar 20 on the right side of the vehicle. The front pillar 20 extends in the vertical direction of the vehicle, and the windshield glass 18 is fixed to the inner end of the front pillar 20 in the width direction of the vehicle. In addition, the front end of a front side glass 22 is fixed to the outer end of the front pillar 20 in the width direction of the vehicle. The left end of the windshield glass 18 is fixed to a front pillar on the left side of the vehicle (not shown).

[0018] Here, a first display unit 24 is provided on the windshield glass 18. The first display unit 24 is configured by a projection surface onto which an image is projected by a head-up display device 23 shown in Fig. 2. Specifically, the head-up display device 23 is provided on the vehicle forward side of the instrument panel 14, and is configured so that an image is projected from the head-up display device 23 onto the first display unit 24 of the windshield glass 18.

[0019] A second display unit 26 is provided below the first display unit 24. The second display unit 26 is a display unit displayed on a meter 25, which is located in front of the driver's seat on the instrument panel 14. The first display unit 24 and the second display unit 26 are provided in positions visible to the driver, and correspond to the "display unit" of the present invention. The vehicle display control device 10, the first display unit 24, and the second display unit 26 form a "vehicle display system" of the present invention.

[0020] (Hardware configuration of the vehicle display control device 10) As shown in FIG. 2, the vehicle display control device 10 of this embodiment includes an ECU (Electronic Control Unit) .

[0021] The ECU 28 includes a CPU (Central Processing Unit: processor) 30, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 34, a storage 36, and an input / output interface 38. Each component is connected to each other via an internal bus 39 so as to be able to communicate with each other.

[0022] The CPU 30 is a central processing unit that executes various programs and controls each part. That is, the CPU 30 reads a program from the ROM 32 or the storage 36, and executes the program using the RAM 34 as a working area. The CPU 30 also controls each of the above components and performs various arithmetic processing according to the program recorded in the ROM 32 or the storage 36.

[0023] The ROM 32 stores various programs and various data. The RAM 34 temporarily stores programs or data as a working area. The storage 36 is composed of an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and is a non-temporary recording medium that stores various programs including an operating system and various data. In this embodiment, the ROM 32 or the storage 36 stores a display program for performing display processing, etc. In addition, various input / output devices are connected to the input / output interface 38.

[0024] Here, the ECU 28 is electrically connected to the automatic driving ECU 40. Like the ECU 28, the automatic driving ECU 40 is configured to include a CPU, a ROM, a RAM, a storage, an input / output interface, and the like (not shown).

[0025] The autonomous driving ECU 40 is connected to a sensor group 42 that detects the current state of the vehicle and an actuator group 44 that controls the traveling of the vehicle. The sensor group 42 includes a plurality of sensors among various sensors such as a camera, a radar, a LIDAR (Light Detection and Ranging or Laser Imaging Detection and Ranging), and a GPS (global positioning system) sensor. The camera captures the surroundings of the vehicle. The radar detects the distance and direction of an object in the surroundings of the vehicle by radio waves. The LIDAR detects the distance and direction of an object in the surroundings of the vehicle by laser light. The GPS sensor detects the current position of the vehicle. In addition, the sensor group 42 includes a sensor that detects the state of the occupant. For example, the sensor group 42 may include a biological sensor that detects the heart rate and wakefulness of the occupant.

[0026] The actuator group 44 includes an acceleration / deceleration actuator that adjusts the acceleration / deceleration of the vehicle, and a steering actuator that drives a steering device of the vehicle. The autonomous driving ECU 40 performs autonomous driving of the vehicle by controlling the operation of the actuator group 44 in accordance with the current situation of the vehicle detected by the sensor group 42. Note that a planned route indicating a route along which the vehicle is planned to travel is stored in a memory unit of the autonomous driving ECU 40, and the autonomous driving ECU 40 drives the vehicle along the planned route stored in the memory unit.

[0027] An accelerator position sensor 46 and a steering sensor 48 are connected to the ECU 28. The accelerator position sensor 46 is a sensor that detects the position of an accelerator pedal (not shown) provided under the driver's seat. The steering sensor 48 is a sensor that detects the load applied to the steering wheel 16 by the occupant. That is, the steering sensor 48 of this embodiment is configured not to detect the load when the steering wheel 16 is operated by the automatic driving ECU 40 during automatic driving, but to detect the load when the steering wheel 16 is operated by the occupant.

[0028] (Functional configuration of the vehicle display control device 10) The vehicular display control device 10 uses the above hardware resources to realize various functions. The functional configuration realized by the vehicular display control device 10 will be described with reference to FIG.

[0029] 3, the vehicle display control device 10 includes, as functional components, a driving mode acquisition unit 52, a peripheral information display unit 54, an operation intervention detection unit 56, a display change unit 58, and a warning display unit 60. Each functional component is realized by the CPU 30 of the ECU 28 reading and executing a program. The display control unit of the present invention includes a function including the peripheral information display unit 54 and the display change unit 58.

[0030] The driving mode acquisition unit 52 acquires whether the driving mode of the vehicle 12 is a manual driving mode or an automatic driving mode. Here, the manual driving mode in this embodiment refers to a driving mode in which the vehicle 12 runs via the driving operation of the occupant. Also, the automatic driving mode in this embodiment refers to a driving mode in which the vehicle 12 runs without the operation of the steering wheel 16 or the accelerator by the occupant. The driving mode acquisition unit 52 may acquire information regarding the driving mode based on a signal from the automatic driving ECU 40, for example.

[0031] The surrounding information display unit 54 constituting the display control unit displays surrounding information of the vehicle 12 on the first display unit 24 and the second display unit 26 provided in the vehicle cabin when the driving mode acquired by the driving mode acquisition unit 52 is at least the autonomous driving mode. Specifically, the surrounding information display unit 54 acquires signals from the sensor group 42, and displays surrounding information of the vehicle 12 based on the acquired signals on the first display unit 24 and the second display unit 26.

[0032] FIG. 4 shows a part of the display screen of the second display unit 26 in the autonomous driving mode. As shown in FIG. 4, in the autonomous driving mode, a host vehicle image M1 simulating the vehicle 12 is displayed at the bottom of the second display unit 26. Also, a preceding vehicle image M2 simulating a preceding vehicle traveling ahead of the vehicle 12 is displayed. Furthermore, a surrounding vehicle image M3 simulating a surrounding vehicle traveling in a lane adjacent to the lane in which the vehicle 12 is traveling is displayed. Here, the preceding vehicle image M2 and the surrounding vehicle image M3 are displayed on the second display unit 26 by the function of the surrounding information display unit 54. Also, when the preceding vehicle and the surrounding vehicle are not traveling within a predetermined range with respect to the vehicle 12, the preceding vehicle image M2 and the surrounding vehicle image M3 are not displayed on the second display unit 26.

[0033] Moreover, an image M4 indicating the current speed of the vehicle 12 is displayed at the top of the second display section 26, and an image M5 indicating the set speed is displayed below this image M4.

[0034] Furthermore, between the host vehicle image M1 and the preceding vehicle image M2, a trajectory image M6 indicating the planned driving route of the vehicle 12 and a speed mark M7 corresponding to the speed of the vehicle 12 are displayed. The trajectory image M6 is displayed in a substantially strip-like shape, and when the vehicle 12 is traveling straight, it is displayed in a substantially linear shape in the up-down direction. Although not shown, when the vehicle 12 turns right or left, or turns along a curve, the trajectory image M6 is displayed in a curved state along the planned driving route of the vehicle 12. This trajectory image M6 is displayed on the second display unit 26 by the function of the surrounding information display unit 54.

[0035] The speed marks M7 are displayed at intervals in a state where they are superimposed on the trajectory image M6, and four speed marks M7 are displayed in Fig. 4. The speed marks M7 are displayed so that the intervals between them change according to the speed of the vehicle 12. For example, when the speed of the vehicle 12 is slower than the state in Fig. 4, the speed marks M7 are displayed so that the intervals between them become narrower. Conversely, when the speed of the vehicle 12 is faster than the state in Fig. 4, the speed marks M7 are displayed so that the intervals between them become wider. The speed marks M7 are displayed on the second display unit 26 by the function of the surrounding information display unit 54.

[0036] The first display unit 24 displays an image similar to that of the second display unit 26. In this embodiment, since the display area of ​​the first display unit 24 is smaller than that of the second display unit 26, the first display unit 24 is configured to display a part of the image of the second display unit 26. For example, the first display unit 24 displays a leading vehicle image M2, a trajectory image M6, and a speed mark M7.

[0037] The operation intervention detection unit 56 shown in FIG. 3 detects an intervention of the driving operation by the occupant when the driving mode acquired by the driving mode acquisition unit 52 is the automatic driving mode. That is, the operation intervention detection unit 56 functions only when the driving mode is the automatic driving mode, and does not function when the driving mode is the manual driving mode. In addition, when the operation intervention detection unit 56 detects that the accelerator pedal has moved from the initial position based on a signal from the accelerator position sensor 46 in the automatic driving mode, it determines that the accelerator operation has been intervened by the occupant. Furthermore, when the operation intervention detection unit 56 detects that the occupant has applied a load to the steering wheel 16 based on a signal from the steering sensor 48 in the automatic driving mode, it determines that the steering operation has been intervened by the occupant.

[0038] The display change unit 58, which constitutes the display control unit, changes the background color of the surrounding information of the vehicle 12 displayed on the first display unit 24 and the second display unit 26 when the operation intervention detection unit 56 detects intervention in driving operations by an occupant.

[0039] In this embodiment, as an example, when the operation intervention detection unit 56 detects an intervention in a driving operation, the display change unit 58 changes the background color of the second display unit 26 from the state shown in Fig. 4 to that shown in Fig. 5. Note that the background color is not particularly specified, and the display change unit 58 changes the background color to an extent that can alert the occupants.

[0040] For example, as shown in Fig. 4, in a normal state where no driving operation is detected, the background color of the second display section 26 is colorless. In contrast, as shown in Fig. 5, when a driving operation is detected, the display change section 58 tones down the background color of the second display section 26 to gray. At this time, the vehicle image M1 and the lane are not toned down, and only the color of the surroundings is toned down.

[0041] Furthermore, the display change unit 58 displays the color of the preceding vehicle in a toned-down manner when the operation intervention detection unit 56 detects an accelerator operation. Furthermore, the display change unit 58 hides the speed mark M7 when the operation intervention detection unit 56 detects an accelerator operation.

[0042] Fig. 5 is a display screen of the second display unit 26 in a state in which an accelerator operation is being performed during autonomous driving. As shown in Fig. 5, the color of the preceding vehicle image M2 is toned down by the display change unit 58. By displaying the color of the preceding vehicle image M2 in a toned down manner in this manner, it is indicated that the driving assistance function that automatically adjusts the distance from the preceding vehicle is not enabled.

[0043] In addition, the speed mark M7 that was superimposed on the trajectory image M6 of the planned travel route by the display changing unit 58 is hidden. In other words, this indicates that the speed of the vehicle 12 is not being controlled because the driver is depressing the accelerator pedal.

[0044] Furthermore, when the accelerator operation is intervening during automatic driving, the display change unit 58 displays the set speed image M5 in a toned-down manner, thereby indicating that the set speed function is not enabled.

[0045] The display change unit 58 hides the trajectory image M6 when the operation intervention detection unit 56 detects an intervention in a steering operation. Fig. 6 shows the display screen of the second display unit 26 in a state in which an intervention in a steering operation is being performed during autonomous driving. As shown in Fig. 6, the trajectory image M6 is hidden by the display change unit 58. In addition, with the trajectory image M6 being hidden, the speed mark M7 is also hidden.

[0046] In addition, in Fig. 6, the preceding vehicle image M2 is not toned down and is displayed in the same manner as in Fig. 4. That is, in Fig. 6, since the accelerator operation is not performed, the driving assistance function that adjusts the distance from the preceding vehicle is operating. Also, since the steering wheel 16 is operated, it is displayed that the function of traveling along the planned traveling route is disabled.

[0047] The warning display unit 60 shown in FIG. 3 displays a warning indicating the intervention of a driving operation on the first display unit 24 and the second display unit 26 when the operation intervention detection unit 56 detects the intervention of a steering operation and an accelerator operation.

[0048] 5 and 6, when at least one of a steering operation and an accelerator operation is being performed, a warning image M8 is displayed to the left of an image M4 that displays the speed of the vehicle 12. The warning image M8 in this embodiment is, as an example, an image showing a state in which the steering wheel is being gripped, but is not limited thereto. For example, a modified example shown in FIG. 7 may be displayed.

[0049] (Modification) 7 shows a modified example of the display screen of the second display unit 26 in a state in which an accelerator operation is being performed during autonomous driving. As shown in FIG. 7, the display change unit 58 displays the preceding vehicle image M2 and the set speed image M5 in a toned-down manner. In addition, the warning display unit 60 displays a warning image M9 to the left of the image M4 displaying the speed of the vehicle 12. The warning image M9 is an image of the accelerator pedal being depressed. In this way, the warning display unit 60 may display differently when a steering operation is detected by the operation intervention detection unit 56 and when an accelerator operation is detected.

[0050] (action) Next, the operation of this embodiment will be described.

[0051] (An example of display processing) 8 is a flowchart showing an example of the flow of display processing by the vehicle display control device 10. This display processing is executed by the CPU 30 of the ECU 28 reading a program from the ROM 32 or the storage 36, expanding it in the RAM 34, and executing it.

[0052] 8, the CPU 30 acquires the driving mode in step S102. Specifically, the CPU 30 acquires, by the function of the driving mode acquisition unit 52, whether the driving mode of the vehicle 12 is the manual driving mode or the automatic driving mode.

[0053] In step S104, the CPU 30 determines whether the driving mode of the vehicle 12 is the automatic driving mode. If the driving mode of the vehicle 12 acquired by the driving mode acquisition unit 52 is the automatic driving mode, the CPU 30 makes an affirmative determination in step S104 and proceeds to processing in step S106. On the other hand, if the driving mode of the vehicle 12 acquired by the driving mode acquisition unit 52 is the manual driving mode, the CPU 30 ends the display processing.

[0054] The CPU 30 displays the surrounding information in step S106. Specifically, the CPU 30 acquires signals from the sensor group 42 using the function of the surrounding information display unit 54, and displays the surrounding information of the vehicle 12 based on the acquired signals on the first display unit 24 and the second display unit 26. For example, as shown in Fig. 4 in step S106, the CPU 30 displays the host vehicle image M1, the leading vehicle image M2, the surrounding vehicle image M3, the trajectory image M6, the speed mark M7, and the like on the second display unit 26. The CPU 30 also displays the same image as that on the second display unit 26 on the first display unit 24.

[0055] The CPU 30 determines whether or not an accelerator operation has been performed in step S108. Specifically, when the CPU 30 detects an accelerator operation based on a signal from the accelerator position sensor 46 by the function of the operation intervention detection unit 56, the CPU 30 makes an affirmative determination in step S108 and proceeds to processing in step S110.

[0056] On the other hand, if the operation intervention detection unit 56 has not detected an accelerator operation intervention in step S108, the CPU 30 makes a negative determination in step S108 and proceeds to the process of step S112.

[0057] In step S110, the CPU 30 performs a display when an accelerator operation is intervened. Specifically, the CPU 30 changes the background color of the second display unit 26 as shown in FIG. 5 by using the function of the display change unit 58. The CPU 30 also uses the function of the display change unit 58 to display the preceding vehicle image M2 and the set speed image M5 in a toned-down manner, and does not display the speed mark M7. Furthermore, in step S110, the CPU 30 uses the function of the warning display unit 60 to display a warning image M8. Although not shown, the display of the first display unit 24 is also changed in a similar manner.

[0058] The CPU 30 determines whether or not a steering operation has been performed in step S112. Specifically, when the CPU 30 detects an intervention of a steering operation based on a signal from the steering sensor 48 by the function of the operation intervention detection unit 56, the CPU 30 makes an affirmative determination in step S112 and proceeds to processing in step S114.

[0059] On the other hand, if the operation intervention detection unit 56 has not detected an intervention of a steering operation in step S112, the CPU 30 makes a negative determination in step S112 and ends the display process.

[0060] The CPU 30 performs display when a steering operation is intervened in step S114. Specifically, the CPU 30 changes the background color of the second display unit 26 as shown in FIG. 6 by the function of the display change unit 58. The CPU 30 also hides the trajectory image M6 indicating the planned driving route and the speed mark M7 by the function of the display change unit 58. Furthermore, the CPU 30 displays a warning image M8 by the function of the warning display unit 60 in step S114. Although not shown, the display is changed in the first display unit 24 in a similar manner. The CPU 30 then ends the display process.

[0061] The state shown in FIG. 6 is a display when the determination in step S108 is negative and the determination in step S112 is positive. That is, FIG. 6 shows a display example when the accelerator operation is not intervened and the steering operation is intervened. On the other hand, when the determination in step S108 is positive and the determination in step S112 is positive, that is, when both the accelerator operation and the steering operation are intervened, the display in FIG. 5 and the display in FIG. 6 are combined. In this case, the CPU 30 changes the background color of the second display section 26 as shown in FIG. 5 or FIG. 6 by the function of the display change section 58. Also, the CPU 30 displays the preceding vehicle image M2 and the set speed image M5 in a toned-down manner by the function of the display change section 58, and hides the trajectory image M6 and the speed mark M7 indicating the planned driving route. Furthermore, the CPU 30 displays the warning image M8 by the function of the warning display section 60.

[0062] As described above, in the vehicle display control device 10 according to this embodiment, when the driving mode acquired by the driving mode acquisition unit is at least the autonomous driving mode, the surrounding information display unit 54 displays surrounding information of the vehicle 12 on the first display unit 24 and the second display unit 26. As a result, in the autonomous driving mode, the occupant can check the surrounding information of the vehicle 12 by looking at the first display unit 24 and the second display unit 26.

[0063] Furthermore, in this embodiment, when the operation intervention detection unit 56 detects an intervention in a driving operation, the display change unit 58 changes the background information of the peripheral information of the vehicle 12 displayed on the first display unit 24 and the second display unit 26. As a result, when an occupant unconsciously performs a driving operation while traveling in the autonomous driving mode, the background of the first display unit 24 and the second display unit 26 changes, so that the occupant can be visually notified of the intervention in the driving operation. For example, when an occupant unconsciously depresses the accelerator pedal with the foot that was resting on the accelerator pedal, the occupant can be alerted that an intervention in the accelerator operation is being performed.

[0064] Here, in this embodiment, by visually alerting occupants, it is possible to prevent other occupants from losing their comfort, compared to a configuration in which frequent audio notifications are given.

[0065] Furthermore, in this embodiment, the surrounding information display unit 54 displays the planned driving route on the first display unit 24 and the second display unit 26, so that the occupant can grasp the planned driving route at a glance even in the autonomous driving mode. When a steering operation is performed, the display change unit 58 hides the image M6 of the planned driving route, so that the occupant can recognize that the steering wheel 16 is being operated.

[0066] Furthermore, in this embodiment, the surrounding information display unit 54 displays the preceding vehicle image M2 on the first display unit 24 and the second display unit 26, so that the occupant can recognize the presence of the preceding vehicle at a glance even in the autonomous driving mode. Furthermore, when an accelerator operation is performed, the display change unit 58 displays the preceding vehicle image M2 in a toned-down color, so that the occupant can recognize that the accelerator operation is being performed.

[0067] In this embodiment, the surrounding information display unit 54 displays the speed mark M7 on the first display unit 24 and the second display unit 26, so that the occupant can check the speed of the vehicle 12 simply by checking the interval between the speed marks M7 even in the autonomous driving mode. When an accelerator operation is performed, the display change unit 58 makes the speed mark M7 invisible, so that the occupant can recognize that the accelerator operation is being performed.

[0068] Furthermore, in this embodiment, the warning display unit 60 displays the warning image M8 on the first display unit 24 and the second display unit 26, so that the occupant can be effectively notified that a driving operation is being intervened. At this time, as in the modified example shown in Fig. 7, by changing the warning image depending on whether an accelerator operation is being intervened or a steering operation is being intervened, the occupant can easily understand the type of driving operation.

[0069] Although the vehicle display control device 10 according to the embodiment has been described above, it is needless to say that the present invention can be embodied in various forms without departing from the scope of the present invention. For example, in the above embodiment, the display change unit 58 is configured to change the background information of the first display unit 24 and the second display unit 26 when an accelerator operation and a steering operation are performed, but the present invention is not limited to this. The background information of the first display unit 24 and the second display unit 26 may also be changed when other driving operations are performed. For example, when a turn signal is operated, the display change unit 58 may change the background information of the first display unit 24 and the second display unit 26. Also, when the brake pedal is depressed, the display change unit 58 may change the background of the first display unit 24 and the second display unit 26.

[0070] In the above embodiment, the accelerator operation is detected based on the signal from the accelerator position sensor 46, but the present invention is not limited to this. For example, in a vehicle in which acceleration and deceleration are performed by operating an operation unit such as a button or lever instead of an accelerator pedal, the accelerator operation may be detected based on a signal from this operation unit.

[0071] Furthermore, in the above embodiment, the intervention of a steering operation is detected based on the signal from the steering sensor 48, but this is not limiting. For example, in a vehicle in which steering is performed by operating an operating unit such as a button or lever instead of the steering wheel 16, the intervention of a steering operation may be detected based on a signal from this operating unit.
