Note that touch panels may also be provided in the second display unit 25 and the third display unit 26. The display area V1 is an example of a "first display area."

[0021] The second display device 44 displays an image in a display area V2 of the second display unit 25. The second display unit 25 of this embodiment is set above the vehicle of the third display unit 26, which will be described later, and is configured as a projection surface onto which an image is projected by the second display device 44. The second display device 44 is a head-up display device provided on the vehicle front side of the instrument panel, and is configured so that an image is projected from the second display device 44, which is a head-up display device, onto the second display unit 25 on the windshield glass 18 (see FIG. 3). In other words, the second display unit 25 is configured as part of the windshield glass 18, which is the projection surface for the head-up display device. The display area V2 is an example of a "second display area."

[0022] In the present embodiment, as an example, the second display device 44 is a so-called Augmented Reality Head Up Display (AR-HUD) that is configured to be able to superimpose and display an image on the foreground of the vehicle 12. That is, the second display device 44 is The angle of view is determined based on the eye point of the occupant in the driver's seat and the imaging plane of a virtual range in space where a virtual image can be formed. The second display device 44 is configured to control the display position so that the positional relationship between the eye point of the occupant in the driver's seat, the superimposed object in the foreground, and the superimposed display is continuously maintained.

[0023] The third display device 46 displays an image in a display area V3 of the third display unit 26. In this embodiment, the third display unit 26 is a meter display located on the right side of the vehicle in the instrument panel. The third display unit 26 is connected to various meter devices mounted on the vehicle 12, and is located in a position within the driver's field of view when the driver is looking ahead of the vehicle.

[0024] The surrounding information acquisition sensor group 56 includes a GPS (global positioning system) device 58, an in-vehicle It comprises a communication device 60, a radar device 62 and a camera 64.

[0025] The radar device 62 is a sensor for detecting objects such as pedestrians and other vehicles around the vehicle, and is configured to include multiple radar devices with different detection ranges. For example, the radar device 62 may be configured to include a LIDAR (Light Detection and Ranging) or the like. The radar device 62 may also be configured to acquire the relative position and relative speed between the detected object and the vehicle. The camera 64 captures images of the surroundings of the vehicle and outputs the captured images. For example, the camera 64 is configured to include a front camera that captures images in front of the vehicle, a rear camera that captures images behind the vehicle, and side cameras that capture images on both the left and right sides of the vehicle.

[0026] The vehicle information acquisition sensor group 66 includes a vehicle speed sensor 68, an acceleration sensor 70, and a steering angle sensor 72. The vehicle speed sensor 68 directly or indirectly detects and outputs the vehicle speed. The acceleration sensor 70 directly or indirectly detects and outputs the vehicle acceleration. The steering angle sensor 72 directly or indirectly detects and outputs the steering angle of the vehicle.

[0027] The autonomous driving ECU 34 is a control unit for performing autonomous driving processing to drive the vehicle automatically without any driving operation by the occupant, and this autonomous driving ECU 48 is electrically connected to a throttle actuator 50, a brake actuator 52, and a steering actuator 54. The throttle actuator 50 is an actuator that changes the throttle opening of the vehicle, and the brake actuator 52 is an actuator that changes the braking force generated by the vehicle's braking device. The steering actuator 54 is an actuator that changes the steering amount by the vehicle's steering device.

[0028] Here, in the autonomous driving processing by the autonomous driving ECU 34, the situation of the vehicle and its surroundings is determined based on information obtained from the surrounding information acquisition sensor group 56 and the vehicle information acquisition sensor group 66, and the throttle actuator 50, brake actuator 52, and steering actuator 54 are controlled according to the surrounding situation.

[0029] The vehicular display control device 10 realizes various functions using the above hardware resources. The functional configuration realized by the vehicular display control device 10 will be described with reference to Fig. 2. The vehicle 12 of this embodiment has multiple driving assistance functions, and the vehicle 12 of this embodiment has at least the following driving assistance functions. (1) Advanced Park (AP). This function detects the parking position using ultrasonic sonar, front, rear, left and right cameras, etc., and automatically parks the vehicle in a garage and also assists in exiting the parking position when the driver indicates the parking position displayed on the multimedia display (for example, the first display unit 24 in this embodiment). The automatic operation includes controlling the accelerator, brake, steering, and shift.

[0030] 2, the vehicular display control device 10 includes, as functional components, a setting unit 80, a display control unit 82, and a function control unit 84. Each functional component is realized by the CPU 30 reading and executing a program stored in the ROM 32 or the storage 36.

[0031] The setting unit 80 has a function of setting a recommended parking position. The setting unit 80 of this embodiment detects parking positions around the vehicle 12 and sets a first recommended area and a second recommended area according to the conditions of the detected parking positions. Here, the first recommended area indicates the most recommended parking position, and the second recommended area indicates the parking position next recommended after the parking position indicated by the first recommended area. As an example, the setting unit 80 sets a parking position with no parked vehicles on either side as the first recommended area, and sets a parking position with a parked vehicle on at least one side as the second recommended area. Note that the setting unit 80 may set a parking position recommended based on the overall conditions of the parking lot (e.g., the positions of adjacent buildings, the positions of the entrances and exits to the parking lot, etc.). Furthermore, the setting unit 80 may set multiple first recommended areas and multiple second recommended areas. Furthermore, the setting unit 80 may set a third recommended area or subsequent areas indicating the parking position next recommended after the parking position indicated by the second recommended area.

[0032] The display control unit 82 has a function of displaying information indicating a recommended parking position. The display control unit 82 of this embodiment causes the information indicating the recommended parking position set by the setting unit 80 to be displayed on the first display unit 24 and the second display unit 25. Note that the display control unit 82 may also cause some or all of the information to be displayed on the first display unit 24 to be displayed on the third display unit 26.

[0033] The display control unit 82 also has a function of displaying telltales indicating the operation states of the operation functions in a manner that moves in accordance with the detected gesture operation. For example, the display control unit 82 displays telltales indicating the operation states of the operation functions of the vehicle 12 in a manner that moves in accordance with a slide operation detected on a touch panel provided on the first display unit 24. Herein, the operation functions include driving operations such as a steering function indicating steering operation and an acceleration / deceleration function indicating accelerator and brake operation. Furthermore, the operation states of the operation functions include a manual operation mode in which the driving operation is performed by the occupant, and an automatic operation mode in which the driving operation is performed by the automatic driving ECU 48. Hereinafter, the telltales indicating the operation states of the operation functions will also be simply referred to as "telltales." A telltale is an example of a "functional image."

[0034] The function control unit 84 has a function of changing the operating state of the operation function. The function control unit 84 of this embodiment switches the operation function between a manual operation mode and an automatic operation mode in response to a gesture operation on a telltale.

[0035] Next, with reference to FIGS. 3 and 4, examples of displays displayed in the display area V1 of the first display unit 24 and the display area V2 of the second display unit 25 according to this embodiment will be described. FIG. 3 shows an example of a display when attempting to park at a recommended parking position using the advanced parking function of the vehicle 12. FIG. 4 shows an example of a display when the vehicle 12 is moving slowly on a one-way road in a parking lot. The display example shown in FIG. 3(A) is displayed in the display area V2, and the display example shown in FIG. 3(B) is displayed in the display area V1. The display example shown in FIG. 4(A) is displayed in the display area V2, and the display example shown in FIG. 4(B) is displayed in the display area V1. For ease of explanation, FIGS. 3(A) and 4(A) show only a portion of the windshield glass 18 in section.

[0036] As shown in FIG. 3(A), the display area V2 shows the foreground, which is the view ahead of the vehicle 12 through the windshield glass 18. Also displayed in the display area V2 is an area marker M2 indicating a recommended parking position. The area marker M2 is an AR (Augmented Reality) image superimposed on the foreground of the vehicle 12. AR images include 2D images and 3D images. The area marker M2 includes an area marker M2a corresponding to an area image M1a (described later) and an area marker M2b corresponding to an area image M1b (described later). The area marker M2 is an example of "area information."

[0037] The area marker M2a is displayed in green to indicate the range of the parking position located diagonally forward to the right of the vehicle 12 and closest to the vehicle that can be displayed in the display area V2. The area marker M2b is displayed in orange to indicate the range of the parking position located diagonally forward to the right of the vehicle 12 and second closest to the vehicle that can be displayed in the display area V2. Green is an example of a "specific color." Orange is an example of a "color different from the specific color."

[0038] As shown in FIG. 3(B), display area V1 displays a host vehicle image M10 simulating the vehicle 12, an overhead image M11 simulating the surrounding conditions of the vehicle 12, and an area image M1 indicating a recommended parking position. The overhead image M11 includes an overhead image M11W simulating the surrounding conditions in a wide area and an overhead image M11N simulating the surrounding conditions in a narrow area. Area image M1 also includes an area image M1a indicating a first recommended area and an area image M1b indicating a second recommended area. Display area V1 also displays a telltale T1 indicating that the operation function is in the automatic operation mode and a telltale T2 indicating that the operation function is in the manual operation mode. Telltale T1 includes a telltale T1a corresponding to the steering function and a telltale T1b corresponding to the acceleration / deceleration function. Telltale T2 also includes a telltale T2a corresponding to the steering function and a telltale T2b corresponding to the acceleration / deceleration function. 3(B) indicates the direction and trajectory of the detected slide operation. In addition, the up-down direction in the display area V1 of this embodiment coincides with the front-rear direction of the host vehicle image M10, and the left-right direction in the display area V1 coincides with the left-right direction of the host vehicle image M10. The overhead image M11 is an example of a "peripheral image."

[0039] The host vehicle image M10 is displayed superimposed on the overhead-view image M11 at a position approximately at the center of the overhead-view image M11. In this embodiment, the host vehicle image M10 is displayed superimposed on both the overhead-view images M11W and M11N. The overhead-view image M11W is an image simulating the surrounding conditions viewed from directly above within a range of approximately 12 m in the forward / backward direction and approximately 20 m in the left / right direction, centered on the vehicle 12, and is displayed in approximately 70% of the area from left to right of the display area V1. The overhead-view image M11N is an image simulating the surrounding conditions viewed from directly above within a range of approximately 10 m in the forward / backward direction and approximately 7 m in the left / right direction, centered on the vehicle 12, and is displayed in the remaining area of ​​the display area V1. Note that the overhead-view image M11N may be displayed by combining an image actually captured by the camera 64 of the vehicle 12 with an image simulating the surrounding conditions.

[0040] The area image M1a is displayed in green in an area diagonally forward to the right of the host vehicle image M10, indicating the parking position closest to the host vehicle image M10. The area image M1b is displayed in orange in an area diagonally forward to the right of the host vehicle image M10, indicating the second-closest parking position from the host vehicle image M10. The telltale T1 is displayed in gray in a central upper position of the overhead-view image M11W. The telltale T2 is displayed in dark green in a position near the front of the host vehicle image M10 on the overhead-view image M11W. The position near the front of the host vehicle image M10 is a position in front of the host vehicle image M10 within a predetermined range. In this embodiment, the telltale T1a is displayed in the central upper position of the overhead-view image M11W, and the telltale T2b is displayed in a position near the front of the host vehicle image M10.

[0041] In this way, by displaying the area image M1a in green in the display area V1 and the area marker M2a in green in the display area V2, the first recommended area in the display area V1 is shown to correspond to the first recommended area in the foreground seen through the display area V2. Also, by displaying the area image M1b in orange in the display area V1 and the area marker M2b in orange in the display area V2, the second recommended area in the display area V1 is shown to correspond to the second recommended area in the foreground seen through the display area V2. The display of the telltales T1a and T2b indicates that the advanced park function of the vehicle 12 is activated. Furthermore, the detection of a slide operation on the telltale T1a toward the host vehicle image M10 indicates that the steering function will be changed from automatic operation mode to manual operation mode.

[0042] Next, the display example shown in Fig. 4 will be described, focusing on differences from Fig. 3. Note that other configurations are the same as those in Fig. 3 described above, and detailed description thereof will be omitted.

[0043] As shown in FIG. 4(A), a direction marker M3 indicating the direction to the recommended parking position is displayed in the display area V2. The direction marker M3 is an AR image superimposed on the foreground of the vehicle 12. The direction marker M3 includes a direction marker M3a corresponding to the area image M1a and a direction marker M3b corresponding to the area marker M2a. In this embodiment, the up-down direction in the display area V2 coincides with the up-down direction of the vehicle 12, and the left-right direction in the display area V2 coincides with the left-right direction of the vehicle 12. The direction marker M3 is an example of "area information."

[0044] The direction marker M3a is displayed in green at the bottom left corner of the display area V2, slightly below the direction marker M3b and pointing left, while the direction marker M3b is displayed in orange at the bottom left corner of the display area V2, slightly above the direction marker M3a and pointing left.

[0045] In this way, the direction markers M3a and M3b are displayed in the lower left corner of the display area V2 pointing to the left, indicating that the first recommended area and the second recommended area are located diagonally rearward and to the left of the vehicle 12. Furthermore, the direction marker M3b is displayed in the lower left corner of the display area V2 slightly above the direction marker M3a, indicating that the second recommended area and the first recommended area are located diagonally rearward and to the left of the vehicle 12, in that order from closest to the vehicle 12.

[0046] As shown in FIG. 4(B), area images M1b and M1a are displayed in order from the closest to the vehicle image M10 in an area indicating the parking position diagonally rearward to the left of the vehicle image M10.

[0047] In this way, by displaying the region image M1a in green in the display region V1 and the direction marker M3a in green in the display region V2, the first recommended region in the display region V1 and the direction of the first recommended region that exists outside the range of the display region V2 are shown in correspondence with each other. Also, by displaying the region image M1b in orange in the display region V1 and the direction marker M3b in orange in the display region V2, the second recommended region in the display region V1 and the direction of the second recommended region that exists outside the range of the display region V2 are shown in correspondence with each other.

[0048] 5 is a flowchart showing an example of the flow of the display process according to this embodiment. As an example, the display process according to this embodiment is a process that is repeatedly executed from when the vehicle 12 enters the parking lot until parking is completed.

[0049] 5, the CPU 30 detects parking positions around the vehicle 12. Specifically, the CPU 30 detects available parking positions around the vehicle 12. In this embodiment, the CPU 30 preferentially detects parking positions that are in the traveling direction of the vehicle 12. That is, if no parking positions are detected in front of the vehicle 12, the CPU 30 detects parking positions behind the vehicle 12.

[0050] In step S101, the CPU 30 selects one parking position from the detected parking positions.

[0051] In step S102, the CPU 30 determines whether or not a parked vehicle exists on at least one side of the selected parking position. If the CPU 30 determines that a parked vehicle exists on at least one side of the selected parking position (step S102: YES), the process proceeds to step S104. On the other hand, if the CPU 30 determines that a parked vehicle does not exist on at least one side of the selected parking position (step S102: NO), the process proceeds to step S103.

[0052] In step S103, the CPU 30 sets the selected parking position as the first recommended area.

[0053] In step S104, the CPU 30 sets the selected parking position as the second recommended area.

[0054] In step S105, the CPU 30 determines whether the selected parking position is within a range that can be displayed in the display area V2 of the second display unit 25. If the CPU 30 determines that the selected parking position is within a range that can be displayed in the second display unit 25 (step S105: YES), the CPU 30 proceeds to step S106. On the other hand, if the CPU 30 determines that the selected parking position is not within a range that can be displayed in the second display unit 25 (step S105: NO), the CPU 30 proceeds to step S107.

[0055] In step S106, the CPU 30 sets the area of ​​the selected parking position to be displayed in the display area V2 of the second display unit 25. Specifically, the CPU 30 sets the area to display an area marker M2 in the range indicating the selected parking position.

[0056] In step S107, the CPU 30 sets the direction of the selected parking position to be displayed in the display area V2 of the second display unit 25. Specifically, the CPU 30 sets the direction marker M3 to be displayed in the range indicating the selected parking position.

[0057] In step S108, the CPU 30 determines whether or not all detected parking positions have been set. If the CPU 30 determines that all detected parking positions have been set (step S108: YES), the CPU 30 proceeds to step S109. On the other hand, if the CPU 30 determines that all detected parking positions have not been set (step S108: NO), the CPU 30 returns to step S101.

[0058] In step S109, the CPU 30 displays the first recommended region in green in the display region V1 of the first display unit 24 and the display region V2 of the second display unit 25. Specifically, the CPU 30 displays the region image M1a in the display region V1 of the first display unit 24, and displays the region marker M2a or the direction marker M3a in the display region V2 of the second display unit 25 (see FIGS. 3 and 4).

[0059] In step S110, the CPU 30 displays the second recommended region in orange in the display region V1 of the first display unit 24 and the display region V2 of the second display unit 25. Specifically, the CPU 30 displays the region image M1b in the display region V1 of the first display unit 24, and displays the region marker M2b or the direction marker M3b in the display region V2 of the second display unit 25 (see FIGS. 3 and 4). Then, the CPU 30 ends the display process.

[0060] 6 is a flowchart showing an example of the flow of the function control process according to this embodiment. The function control process according to this embodiment is, for example, a process that is repeatedly executed from when the advanced park function of the vehicle 12 is activated until parking of the vehicle 12 is completed.

[0061] In step S200 of Fig. 6, CPU 30 determines whether or not a sliding operation on the host vehicle image M10 relative to the telltale indicating the steering function has been detected. Specifically, CPU 30 determines whether or not a sliding operation on the host vehicle image M10 relative to the telltale T1a has been detected (see Fig. 3(B)). If CPU 30 determines that a sliding operation on the host vehicle image M10 relative to the telltale indicating the steering function has been detected (step S200: YES), CPU 30 proceeds to step S201. On the other hand, if CPU 30 determines that a sliding operation on the host vehicle image M10 relative to the telltale indicating the steering function has not been detected (step S200: NO), CPU 30 proceeds to step S203.

[0062] In step S201, the CPU 30 changes the steering function during automatic parking to a manual operation mode.

[0063] In step S202, the CPU 30 changes the color of the telltale indicating the steering function and displays it around the host vehicle image M10. Specifically, the CPU 30 displays the telltale T2a in a position near the front of the host vehicle image M10.

[0064] In step S203, CPU 30 determines whether or not a sliding operation from the periphery of host vehicle image M10 has been detected for a telltale indicating a steering function. Specifically, CPU 30 determines whether or not a sliding operation from a position near the front of host vehicle image M10 has been detected for telltale T2a. If CPU 30 determines that a sliding operation from the periphery of host vehicle image M10 has been detected for a telltale indicating a steering function (step S203: YES), CPU 30 proceeds to step S204. On the other hand, if CPU 30 determines that a sliding operation from the periphery of host vehicle image M10 has not been detected for a telltale indicating a steering function (step S203: NO), CPU 30 ends the function control process.

[0065] In step S204, the CPU 30 changes the steering function during automatic parking to an automatic operation mode.

[0066] In step S205, CPU 30 changes the color of the telltale indicating the steering function and displays it in the upper part of display area V1 of first display unit 24. Specifically, CPU 30 displays telltale T1a in the upper center position of overhead image M11W displayed in display area V1 of first display unit 24. Then, CPU 30 ends the function control process.

[0067] (Summary of this embodiment) The vehicular display control device 10 of this embodiment displays an overhead image M11 and an area image M1 in a display area V1 of a first display unit 24 provided around the driver's seat of a vehicle 12, and displays an area marker M2 corresponding to the area image M1 in a display area V2 of a second display unit 25 so as to be superimposed on the foreground of the vehicle 12. Therefore, the vehicular display control device 10 of this embodiment allows the occupant to correctly recognize the recommended actual parking position.

[0068] The vehicular display control device 10 of this embodiment displays the area image M1 displayed in the display area V1 and the area marker M2 and direction marker M3 displayed in the display area V2 in the same color. Therefore, according to the vehicular display control device 10 of this embodiment, the occupant can easily understand the correspondence between the area image M1 displayed in different display areas and the area marker M2 and direction marker M3.

[0069] The vehicular display control device 10 of this embodiment displays in green the area image M1a, area marker M2a, and direction marker M3a indicating the first recommended area, which is a parking position with no parked vehicles on either the left or right side, and displays in orange the area image M1b, area marker M2b, and direction marker M3b indicating the second recommended area, which is a parking position with a parked vehicle on at least one side. Therefore, the vehicular display control device 10 of this embodiment allows the occupant to easily understand the correspondence between the information indicating parking positions with different degrees of recommendation displayed in different display areas.

[0070] When a parking position where the vehicle 12 can be parked is outside the range that can be displayed in the display area V2, the vehicular display control device 10 of this embodiment displays a direction marker M3 in the display area V2, indicating the direction in which the parking position is located. Therefore, the vehicular display control device 10 of this embodiment can superimpose the marker M3 on the foreground of the vehicle 12 to guide the driver to a parking position that is outside the range that can be displayed.

[0071] The vehicular display control device 10 of this embodiment changes the operation state of the steering function when a slide operation on a telltale indicating the steering function is detected, and moves the display of the telltale displayed in the display area V1 in accordance with the slide operation. Therefore, the vehicular display control device 10 of this embodiment allows the occupant to easily switch the operation state of the operation function during automatic parking.
