DETAILED DESCRIPTION

[0025] The vehicle display system S according to the embodiment will be described with reference to the accompanying drawings. In this embodiment, the vehicle 12 has an instrument panel (not shown) at the front of the vehicle interior. Additionally, a windshield 18 (see attached figure) is provided at the front end of the instrument panel. Figure 3 The windshield 18 extends vertically and horizontally across the vehicle, dividing the interior and exterior of the vehicle. Additionally, the vehicle 12 is equipped with a vehicle display control device 10 that constitutes the vehicle display system S. In this embodiment, the vehicle display control device 10 is, for example, a display ECU (Electronic Control Unit) that performs various display controls.

[0026] like Figure 1 As shown, the vehicle display system S is configured to include a vehicle display control device 10, a peripheral information acquisition sensor group 56, a vehicle information acquisition sensor group 66, and an autonomous driving ECU 48, which are connected in a communicable manner via a communication bus 74.

[0027] The vehicle display control 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, and a communication interface (communication I / F) 38. All components are connected to each other via an internal bus 40 in a manner enabling communication.

[0028] CPU 30 is the central processing unit, which executes various programs and controls various components. Specifically, CPU 30 reads programs from ROM 32 or storage device 36 and uses RAM 34 as the working area to execute the programs. Furthermore, CPU 30 performs control and various arithmetic operations on the aforementioned components according to the programs recorded in ROM 32 or storage device 36.

[0029] ROM 32 stores various programs and data. RAM 34 serves as a working area to temporarily store programs or data. Storage device 36, consisting of an HDD (Hard Disk Drive) or SSD (Solid State Drive), is a non-temporary recording medium that stores various programs containing the operating system and various data. In this embodiment, the ROM 32 or storage device 36 stores display programs for display processing, function control programs for function control processing, etc.

[0030] The communication I / F38 is an interface used for communication between the vehicle display control device 10 and external servers and other devices, such as using standards like CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark).

[0031] The vehicle display control device 10 is connected to a first display device 42, a second display device 44, and a third display device 46.

[0032] The first display device 42 displays an image on the display area V1 of the first display unit 24. In this embodiment, the first display unit 24 is a central display provided in the center of the dashboard in the vehicle width direction. Furthermore, the first display unit 24 includes a touch panel (not shown) configured to detect gesture operations on the display area V1. The gesture operation information detected by the touch panel of the first display unit 24 is sent to the vehicle display control device 10. Alternatively, the touch panel 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".

[0033] The second display device 44 displays an image in the display area V2 of the second display unit 25. In this embodiment, the second display unit 25 is located on the vehicle-top side of the third display unit 26 (described later) and is composed of a projection surface projected by the second display device 44. The second display device 44 is a head-up display (HUD) located on the vehicle-front side of the dashboard, configured such that images are projected from the second display device 44 (which is the HUD) onto the windshield 18 (see reference 1). Figure 3 The second display unit 25 projects images. That is, the second display unit 25 is part of the windshield 18, which serves as the projection surface of the head-up display device. The display area V2 is an example of a "second display area".

[0034] Furthermore, in this embodiment, as an example, the second display device 44 is configured as a so-called augmented reality head-up display (AR-HUD) capable of displaying images superimposed on the view in front of the vehicle 12. That is, the second display device 44 defines the viewing angle based on the eye point of the occupant sitting in the driver's seat and the imaging surface of an imaginary range in the space where virtual images can be formed. Moreover, the second display device 44 is configured to control the display position in a manner that continuously maintains the positional relationship between the eye point of the occupant sitting in the driver's seat, the overlapping objects in the view in front, and the overlapping display.

[0035] The third display device 46 causes the image to be displayed on the display region V3 of the third display portion 26. The third display portion 26 of the present embodiment is an instrument display located on the right side of the vehicle of the instrument panel. The third display portion 26 is connected to various kinds of instrument devices mounted on the vehicle 12, and is disposed at a position that enters the field of view in a state where the driver's line of sight is directed toward the front of the vehicle.

[0036] The surrounding information acquisition sensor group 56 is configured to include a GPS (global positioning system) device 58, a vehicle-mounted communication device 60, a radar device 62, and a camera 64.

[0037] The radar device 62 is a sensor for detecting objects such as pedestrians, other vehicles, and the like present in the surroundings of the vehicle, and is configured to include a plurality of radar devices whose detection ranges are different from each other. For example, the radar device 62 can also be configured to include a LIDAR (Light Detection and Ranging) or the like. In addition, the radar device 62 can also be configured to acquire the relative position and the relative speed of the detected object with respect to the host vehicle. The camera 64 captures the surroundings of the vehicle and outputs the captured image. For example, the camera 64 is configured to include a front camera that captures the front of the vehicle, a rear camera that captures the rear of the vehicle, side cameras that capture the left and right sides of the vehicle, and the like.

[0038] The vehicle information acquisition sensor group 66 is configured to include a vehicle speed sensor 68, an acceleration sensor 70, and a rudder angle sensor 72. The vehicle speed sensor 68 directly or indirectly detects and outputs the speed of the vehicle. The acceleration sensor 70 directly or indirectly detects and outputs the acceleration of the vehicle. The rudder angle sensor 72 directly or indirectly detects and outputs the steering angle (steering angle) of the vehicle.

[0039] The automatic driving ECU 34 is a control portion for performing an automatic driving process in which the vehicle is automatically driven without accompanying a driving operation by an occupant, and is electrically connected to a throttle actuator 50, a brake actuator 52, and a steering (steering) actuator 54. The throttle actuator 50 is an actuator that changes the throttle opening degree of the vehicle, and the brake actuator 52 is an actuator that changes the braking force generated by the brake device of the vehicle. In addition, the steering actuator 54 is an actuator that changes the steering amount of the steering device of the vehicle.

[0040] Here, in the automatic driving process performed by the automatic driving ECU 34, the situation of the vehicle and its surroundings is judged on the basis of information obtained from the surrounding information acquisition sensor group 56 and the vehicle information acquisition sensor group 66, and the throttle actuator 50, the brake actuator 52, and the steering actuator 54 are controlled in accordance with the surrounding situation.

[0041] The vehicle display control device 10 uses the aforementioned hardware resources to implement various functions. (Refer to...) Figure 2 The functional configuration implemented by the vehicle display control device 10 will be described. Furthermore, the vehicle 12 of this embodiment has multiple driving assistance functions, but the vehicle 12 of this embodiment has at least the following driving assistance functions.

[0042] (1) Advanced Park (AP). This function detects the parking position using ultrasonic sonar, front, rear, left, and right cameras, etc., and displays the parking position on the multimedia (e.g., the first display unit 24 in this embodiment), thereby automatically parking the vehicle. It also assists in exiting the parking position. Automatic operation includes acceleration, braking, steering, and gear shifting.

[0043] like Figure 2 As shown, the vehicle display control device 10 is configured to include a setting unit 80, a display control unit 82, and a function control unit 84 as functional components. Each functional component is implemented by the CPU 30 reading and executing a program stored in the ROM 32 or the storage device 36.

[0044] The setting unit 80 has the function of setting recommended parking positions. In this embodiment, the setting unit 80 detects parking positions around the vehicle 12 and sets a first recommended area and a second recommended area based on the detected parking position conditions. Here, the first recommended area represents the most recommended parking position, and the second recommended area represents a parking position recommended after the parking position shown in the first recommended area. As an example, the setting unit 80 sets a parking position where there are no parked vehicles on either the left or right side as the first recommended area, and sets a parking position where there are parked vehicles on at least one side as the second recommended area. In addition, the setting unit 80 can also set the recommended parking positions based on the overall conditions of the parking lot (e.g., the positions of adjacent buildings, the positions of parking lot entrances and exits, etc.). The setting unit 80 can set multiple first recommended areas and multiple second recommended areas. Furthermore, the setting unit 80 can set a third recommended area and subsequent recommended areas that represent recommended parking positions after the parking positions shown in the second recommended areas.

[0045] The display control unit 82 has the function of displaying information indicating the recommended parking position. In this embodiment, the display control unit 82 causes the first display unit 24 and the second display unit 25 to display information indicating the recommended parking position set by the setting unit 80. In addition, the display control unit 82 can also display part or all of the information displayed on the first display unit 24 on the third display unit 26.

[0046] Further, the display control section 82 has a function of displaying in a manner that the indicator indicating the operating state of the operation function moves in accordance with the detected gesture operation. The display control section 82, for example, displays in a manner that the indicator indicating the operating state of the operation function of the vehicle 12 moves in accordance with the sliding operation detected by the touch panel provided to the first display section 24. Here, the operation function includes a steering function indicating the operation of the steering, a speed-up / down function indicating the operation of the acceleration and the braking, and the like. Further, the operating state of the operation function includes a manual operation mode in which the occupant performs the driving operation, and an automatic operation mode in which the automatic driving ECU 48 performs the driving operation. Hereinafter, the indicator indicating the operating state of the operation function will be simply referred to as the "indicator". The indicator is an example of the "function image".

[0047] The function control section 84 has a function of changing the operating state of the operation function. The function control section 84 of the present embodiment switches the manual operation mode and the automatic operation mode of the operation function in accordance with the gesture operation to the indicator.

[0048] Next, with reference to Figure 3 and Figure 4 , a display example displayed on the display region V1 of the first display section 24 and the display region V2 of the second display section 25 of the present embodiment will be described. Figure 3 is a display example of a case where the occupant wants to park at the recommended parking position by the function of the advanced parking of the vehicle 12. Further, Figure 4 is a display example of a case where the vehicle 12 slowly travels on a one-way road in a parking lot. Further, Figure 3 the display example shown in (A) of Figure 3 the display example shown in (B) of Figure 4 the display example shown in (A) of Figure 4 the display example shown in (B) of Figure 3 the display example shown in (A) of Figure 4 (A), for convenience of explanation, only a part of the windshield 18 is taken out and illustrated.

[0049] As Figure 3As shown in (A), the view in front of the vehicle 12, seen through the windshield 18, can be viewed in display area V2. Additionally, a zone marker M2 indicating a recommended parking position is displayed in display area V2. Zone marker M2 is an AR (Augmented Reality) image overlaid on the view in front of the vehicle 12. The AR image includes both 2D and 3D images. Zone marker M2 includes zone marker M2a corresponding to zone image M1a (described later) and zone marker M2b corresponding to zone image M1b (described later). Zone marker M2 is an example of "zone information".

[0050] Area marker M2a is displayed in green to indicate the parking position located diagonally to the right of vehicle 12 and at the very front of display area V2. Area marker M2b is displayed in orange to indicate the parking position located diagonally to the right of vehicle 12 and at the second position from the front of display area V2. Green is an example of a "specific color." Orange is an example of a "color different from the specific color."

[0051] like Figure 3 As shown in (B), the display area V1 displays a vehicle image M10 simulating the vehicle 12, an overhead view M11 simulating the surrounding conditions of the vehicle 12, and a region image M1 showing recommended parking positions. The overhead view M11 includes an overhead view M11W simulating a wide area (wide range) of the surrounding conditions and an overhead view M11N simulating a narrow area (narrow range) of the surrounding conditions. Furthermore, the region image M1 includes a region image M1a indicating a first recommended region and a region image M1b indicating a second recommended region. Moreover, the display area V1 displays an indicator T1 indicating automatic operation mode and an indicator T2 indicating manual operation mode. Indicator T1 includes an indicator T1a corresponding to the steering function and an indicator T1b corresponding to the acceleration / deceleration function. Additionally, indicator T2 includes an indicator T2a corresponding to the steering function and an indicator T2b corresponding to the acceleration / deceleration function. Figure 3 The solid arrow in (B) indicates the direction and trajectory of the detected sliding operation. Furthermore, in this embodiment, the vertical direction in the display area V1 is consistent with the front-back direction of the vehicle image M10, and the horizontal direction in the display area V1 is consistent with the horizontal direction of the vehicle image M10. The top-view image M11 is an example of a "peripheral image".

[0052] The own vehicle image M10 is displayed so as to overlap the bird's-eye view image M11 at a position in the vicinity of the center of the bird's-eye view image M11. The own vehicle image M10 of this embodiment is displayed so as to overlap both the bird's-eye view image M11W and the bird's-eye view image M11N. The bird's-eye view image M11W is an image simulating a range of about 12 m in the front-rear direction and about 20 m in the left-right direction centered on the vehicle 12 viewed from directly above, and is displayed in a region from the left direction to about 70% of the right direction of the display region V1. In addition, the bird's-eye view image M11N is an image simulating a range of about 10 m in the front-rear direction and about 7 m in the left-right direction centered on the vehicle 12 viewed from directly above, and is displayed in the remaining region of the display region V1. Further, the bird's-eye view image M11N can not be an image simulating the surrounding situation, but can be an image in which a video actually captured by the camera 64 of the vehicle 12 is synthesized and displayed.

[0053] The region image M1a is displayed in green in a region showing a parking position located diagonally to the right of the own vehicle image M10 and closest to the own vehicle image M10. In addition, the region image M1b is displayed in orange in a region showing a parking position located diagonally to the right of the own vehicle image M10 and second closest to the own vehicle image M10. The indicator T1 is displayed in gray at a position in the upper center of the bird's-eye view image M11W. In addition, the indicator T2 is displayed in dark green at a position in the vicinity of the front of the own vehicle image M10 of the bird's-eye view image M11W. Further, the position in the vicinity of the front of the own vehicle image M10 is a position within a prescribed range in front of the own vehicle image M10. In this embodiment, the indicator T1a is displayed in the upper center of the bird's-eye view image M11W, and the indicator T2b is displayed at a position in the vicinity of the front of the own vehicle image M10.

[0054] By displaying the region image M1a in green in the display region V1 and displaying the region mark M2a in green in the display region V2 as well, the first recommended region in the display region V1 is shown in association with the first recommended region in the front view through the display region V2. Further, by displaying the region image M1b in orange in the display region V1 and displaying the region mark M2b in orange in the display region V2 as well, the second recommended region in the display region V1 is shown in association with the second recommended region in the front view through the display region V2. Also, by displaying the indicators T1a and T2b, the function of indicating the advanced parking of the vehicle 12 is shown in the activated state. Also, the case where the steering function is changed from the automatic operation mode to the manual operation mode by detecting the swiping operation toward the own vehicle image M10 with respect to the indicator T1a is shown.

[0055] Next, with respect to the display example shown in FIG. 17, the case where the steering function is changed from the automatic operation mode to the manual operation mode by detecting the swiping operation toward the own vehicle image M10 with respect to the indicator T1a is shown. Figure 4 Figure 3 ​The differences will be explained. Furthermore, other components are similar to those described above. Figure 3 The same applies; detailed explanation omitted.

[0056] like Figure 4 As shown in (A), a direction marker M3 is displayed in display area V2, indicating the direction of the recommended parking position. Direction marker M3 is an AR image displayed overlaid with the view ahead of vehicle 12. Direction marker M3 includes direction marker M3a corresponding to area image M1a and direction marker M3b corresponding to area marker M1b. Furthermore, in this embodiment, the vertical direction in display area V2 corresponds to the vertical direction of vehicle 12, and the horizontal direction in display area V2 corresponds to the horizontal direction of vehicle 12. Direction marker M3 is an example of "area information".

[0057] Direction marker M3a is located in the lower left corner of display area V2, slightly below direction marker M3b, indicating the left direction and is displayed in green. Conversely, direction marker M3b is located in the lower left corner of display area V2, slightly above direction marker M3a, indicating the left direction and is displayed in orange.

[0058] By displaying the left direction using directional markers M3a and M3b in the lower left corner of the display area V2, it is shown that "a first recommended area and a second recommended area exist diagonally to the left rear of vehicle 12". Furthermore, in the lower left corner of the display area V2, directional marker M3b is displayed slightly above directional marker M3a, thus indicating that "a second recommended area and a first recommended area exist sequentially diagonally to the left rear of vehicle 12, starting from the side closest to vehicle 12".

[0059] like Figure 4 As shown in (B), in the area representing the parking position diagonally to the left rear of the vehicle image M10, area images M1b and M1a are displayed sequentially from the side closest to the vehicle image M10.

[0060] By displaying the area image M1a in green in display area V1 and the direction marker M3a in green in display area V2, the first recommended area in display area V1 is shown in association with the direction of the first recommended area existing outside the range of display area V2. Furthermore, by displaying the area image M1b in orange in display area V1 and the direction marker M3b in orange in display area V2, the second recommended area in display area V1 is shown in association with the direction of the second recommended area existing outside the range of display area V2.

[0061] Figure 5is a flowchart showing an example of a flow of display processing according to the present embodiment. As one example, the display processing of the present embodiment is processing that is repeatedly executed from when the vehicle 12 enters the parking lot to when parking is completed.

[0062] In Figure 5 In step S100, the CPU 30 detects a parking position in the vicinity of the host vehicle. Specifically, the CPU 30 detects a parking position in the vicinity of the vehicle 12 in which parking is possible. The CPU 30 of the present embodiment gives priority to detecting a parking position that exists in the advancing direction of the vehicle 12. That is, the CPU 30 detects a parking position in the rear of the vehicle 12 in a case where no parking position is detected in the front of the vehicle 12.

[0063] In step S101, the CPU 30 selects one parking position from among the detected parking positions.

[0064] In step S102, the CPU 30 determines whether a parked vehicle exists on at least one side of the selected parking position. The CPU 30 proceeds to step S104 in a case where it is determined that a parked vehicle exists on at least one side of the selected parking position (step S102: YES). On the other hand, the CPU 30 proceeds to step S103 in a case where it is determined that a parked vehicle does not exist on at least one side of the selected parking position (step S102: NO).

[0065] In step S103, the CPU 30 sets the selected parking position as the first recommended area.

[0066] In step S104, the CPU 30 sets the selected parking position as the second recommended area.

[0067] In step S105, the CPU 30 determines whether the selected parking position is within a range that can be displayed on the display area V2 of the second display portion 25. The CPU 30 proceeds to step S106 in a case where it is determined that the selected parking position is within a range that can be displayed on the second display portion 25 (step S105: YES). On the other hand, the CPU 30 proceeds to step S107 in a case where it is determined that the selected parking position is not within a range that can be displayed on the second display portion 25 (step S105: NO).

[0068] In step S106, the CPU 30 sets the area of the selected parking position to be displayed on the display area V2 of the second display portion 25. Specifically, the CPU 30 sets the area to be displayed within the range of the selected parking position, with the area marker M2.

[0069] In step S107, the CPU 30 is configured to display the direction of the selected parking position on the display area V2 of the second display unit 25. Specifically, the CPU 30 is configured to display a direction marker M3 within the range representing the selected parking position.

[0070] In step S108, the CPU 30 determines whether all detected parking positions have been set. If the CPU 30 determines that all detected parking positions have been set (step S108: Yes), it proceeds to step S109. On the other hand, if the CPU 30 determines that not all detected parking positions have been set (step S108: No), it returns to step S101.

[0071] In step S109, the CPU 30 displays the first recommended area in green in the display area V1 of the first display unit 24 and the display area V2 of the second display unit 25. Specifically, the CPU 30 displays the area image M1a in the display area V1 of the first display unit 24, and displays the area marker M2a or the direction marker M3a in the display area V2 of the second display unit 25 (see reference). Figure 3 and Figure 4 ).

[0072] In step S110, the CPU 30 displays the second recommended area in orange in the display area V1 of the first display unit 24 and the display area V2 of the second display unit 25. Specifically, the CPU 30 displays the area image M1b in the display area V1 of the first display unit 24, and displays the area marker M2b or the direction marker M3b in the display area V2 of the second display unit 25 (see reference). Figure 3 and Figure 4 Then, CPU30 finishes display processing.

[0073] Figure 6 This is a flowchart illustrating an example of the function control processing flow of this embodiment. As an example, the function control processing of this embodiment is a process that is repeatedly executed from the time the advanced parking function of vehicle 12 is activated until the parking of vehicle 12 is completed.

[0074] exist Figure 6 In step S200, the CPU 30 determines whether a sliding operation towards the vehicle image M10 is detected for the indicator representing the steering function. Specifically, the CPU 30 determines whether a sliding operation towards the vehicle image M10 for the indicator T1a is detected (refer to...). Figure 3The CPU 30 proceeds to Step S201 when it is determined that the sliding operation toward the own-vehicle image M10 with respect to the indicator indicating the steering function is detected (Step S200: Yes).
