[0045] [First Implementation Method]

[0046] Referring to the accompanying drawings, a vehicle 12 employing the vehicle display control device 10 according to the first embodiment will be described. Furthermore, as an example, the vehicle 12 of this embodiment includes multiple driving assistance functions, including driving assistance functions related to autonomous driving. Vehicle 12 is an example of "this vehicle." The driving assistance functions are an example of "operating functions."

[0047] The driving assistance functions of the vehicle 12 in this embodiment include a variety of driving assistance functions, but in this embodiment, the following driving assistance function will be used as an example for explanation.

[0048] (1) Radar Cruise Control (ACC / DRCC: Adaptive Cruise Control / Dynamic Radar Cruise Control). This function is a driving assistance function that uses the camera and radar (monocular camera and millimeter-wave radar) included in the sensor group 42 described below to identify the preceding vehicle and assist in following the vehicle while maintaining a vehicle distance corresponding to the vehicle speed.

[0049] (2) Lane Departure Alert (LDA). In this function, when the system determines that the vehicle is likely to deviate from its lane, it notifies the driver to take deviance avoidance actions by using a display and a buzzer or steering vibration. Furthermore, it assists in lane departure suppression by applying steering force to the steering device and displaying the information.

[0050] (3) Lane Tracing Assist (LTA). This function utilizes the system to assist in maintaining a portion of the steering force required to center the vehicle within the same lane during ACC control. A typical use case is highway driving.

[0051] (Inside carriage 12)

[0052] like Figure 1 As shown, an instrument panel 14 is provided at the front of the passenger compartment in vehicle 12. The instrument panel 14 extends in the width direction 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, a right-hand drive vehicle is provided with the steering wheel 16 on the right side, and the driver's seat is located on the right side of the vehicle.

[0053] A windshield 18 is provided at the front end of the dashboard 14. The windshield 18 extends in the vertical direction and the width direction of the vehicle to divide the interior and exterior of the passenger compartment.

[0054] The right-side end of the windshield 18 is fixed to the right-side front pillar 20 of the vehicle. The front pillar 20 extends in the vertical direction of the vehicle, and the windshield 18 is fixed at its inner end in the width direction of the vehicle. Furthermore, the front end of the front side glass 22 is fixed at the outer end of the front pillar 20 in the width direction of the vehicle. Additionally, the left-side end of the windshield 18 is fixed to the left-side front pillar of the vehicle.

[0055] Here, a first display unit 24 is provided on the windshield 18. The first display unit 24 is connected by a... Figure 2The projection surface is formed by the upward-looking display device 23 shown. In detail, it is configured such that the upward-looking display device 23 is provided on the front side of the vehicle compared to the instrument panel 14, and an image is projected from the upward-looking display device 23 toward the first display portion 24 of the windshield 18.

[0056] A second display unit 26 is provided on the lower side of the vehicle compared to the first display unit 24. The second display unit 26 is a display unit that is displayed on the instrument panel 25, which is located in front of the driver's seat in the instrument panel 14. The first display unit 24 and the second display unit 26 are positioned in a location that the driver can visually confirm. Furthermore, the vehicle display control device 10, the first display unit 24, and the second display unit 26 constitute a vehicle display system.

[0057] (Hardware structure of vehicle display control device 10)

[0058] like Figure 2 As shown, the vehicle display control device 10 of the first embodiment is configured to include an ECU (Electronic Control Unit) 28.

[0059] The ECU28 is configured to include a CPU (Central Processing Unit) 30, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 34, a memory 36, and an input / output interface 38. All components are interconnected via an internal bus 39 in a manner that enables them to communicate with each other.

[0060] As an example of a hardware processor, CPU 30 is a central processing unit that executes various programs or controls various parts. Specifically, CPU 30 reads programs from ROM 32 or memory 36 and uses RAM 34 as its working area to execute the programs. Furthermore, CPU 30 implements control over the aforementioned structures and performs various arithmetic operations according to the programs recorded in ROM 32 or memory 36.

[0061] ROM 32 stores various programs and data. RAM 34 serves as a working area for temporary storage of programs or data. Storage 36 is a non-temporary recording medium, constructed of HDD (Hard Disk Drive) or SSD (Solid State Drive), that stores various programs, including the operating system, and various data. In this embodiment, the ROM 32 or storage 36, which is equivalent to memory, stores display programs and the like for implementing display processing. Furthermore, various input / output devices are connected to the input / output interface 38.

[0062] Here, ECU28 and autonomous driving ECU40 are electrically connected together. Like ECU28, autonomous driving ECU40 is configured to include a CPU, ROM, RAM, memory, and input / output interfaces.

[0063] The autonomous driving ECU 40 is connected to a sensor group 42 for detecting the current status of the vehicle and an actuator group 44 for controlling the vehicle's movement. The sensor group 42 includes multiple sensors from various sources, such as cameras, radar, LiDAR (Light Detection and Ranging or Laser Imaging Detection and Ranging), and GPS (Global Positioning System) sensors. The camera captures images of the vehicle's surroundings. The radar uses radio waves to detect the distance and direction of objects in the vehicle's vicinity. The LiDAR uses lasers to detect the distance and direction of objects in the vehicle's vicinity. The GPS sensor detects the vehicle's current position. Furthermore, the sensor group 42 may include sensors that detect the state of the occupants. For example, it could also be configured as a biosensor that detects the occupants' heart rate and level of alertness.

[0064] The actuator assembly 44 includes an acceleration / deceleration actuator for adjusting the vehicle's acceleration and deceleration, and a steering actuator for driving the vehicle's steering mechanism. In the autonomous driving ECU 40, autonomous driving is implemented by controlling the operation of the actuator assembly 44 based on the current state of the vehicle detected by the sensor assembly 42. Furthermore, the autonomous driving ECU 40 stores a predetermined path representing a planned route for the vehicle in its storage unit, and the autonomous driving ECU 40 causes the vehicle to travel along the predetermined path stored in the storage unit.

[0065] An accelerometer position sensor 46 and a steering sensor 48 are connected to the ECU 28. The accelerometer position sensor 46 is a sensor that detects the position of the accelerometer pedal, which is located at the lower part of the driver's seat. Furthermore, 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 in this embodiment is structured such that it does not detect the load when the steering wheel 16 is being operated via the autonomous driving ECU 40 during autonomous driving, but detects the load when the occupant is operating the steering wheel 16.

[0066] (Functional structure of vehicle display control device 10)

[0067] The vehicle display control device 10 uses the aforementioned hardware resources to implement various functions. For the functional structure implemented by the vehicle display control device 10, refer to... Figure 3 Let me explain.

[0068] like Figure 3 As shown, the vehicle display control device 10 of the first embodiment is configured to include a function status acquisition unit 52 and a display control unit 54 as functional structures. Each functional structure is implemented by the CPU 30 of the ECU 28 reading and executing the program.

[0069] The function status acquisition unit 52 has the function of acquiring the operating status of the driving assistance functions of the vehicle 12. The function status acquisition unit 52 acquires information related to the operating status of the driving assistance functions of the vehicle 12 based, for example, on signals from the automatic driving ECU 40. Specifically, the operating status includes a stop state (where the function is not activated), a standby state (where the function can be activated), an activation state (where the function is activated), and an abnormal state (where the function's operation is hindered). A standby state is an example of a "function is invalid." An activation state is an example of a "function is active."

[0070] Furthermore, the function status acquisition unit 52 has the function of detecting changes in the operating status of the driving assistance functions of the vehicle 12. For example, the function status acquisition unit 52 acquires information related to changes in the operating status of the driving assistance functions of the vehicle 12 based on signals from the autonomous driving ECU 40.

[0071] The display control unit 54 has the function of displaying the operating status of the driving assistance functions of the vehicle 12 on a first display unit 24 and a second display unit 26 installed inside the passenger compartment. Specifically, the display control unit 54 displays warning lights indicating the operating status of the driving assistance functions of the vehicle 12 on the first display unit 24 and the second display unit 26 in a manner that changes according to the operating status obtained by the function status acquisition unit 52. Furthermore, the warning light displayed by the display control unit 54 in a manner that changes need to be at least one warning light. An example of a "function image" is the warning light indicating the operating status of the driving assistance functions.

[0072] In this embodiment, the display control unit 54 displays the warning light by moving the warning light indicating the driving assistance function according to the operating state of the driving assistance function of the vehicle 12. Specifically, when the driving assistance function of the vehicle 12 is changed from a standby state to an activated state, the display control unit 54 moves the warning light indicating the driving assistance function from the area that can be fixedly displayed to the vehicle image M10 (refer to the image M10 simulating the vehicle 12). Figure 4A The display is moved to a location near the vehicle image M10. Furthermore, when the driver assistance function is changed from an active state to a standby state, the display control unit 54 moves the warning light indicating the driver assistance function from a location near the vehicle image M10 to a location where it can be displayed permanently. Moreover, while the driver assistance function is active, the display control unit 54 continuously displays the warning light indicating the driver assistance function in a location near the vehicle image. The location near the vehicle image M10 refers, for example, to an area within a pre-defined range in the vehicle image M10. The area where it can be displayed permanently and the location near the vehicle image are examples of "the area surrounding the vehicle image."

[0073] Furthermore, in this embodiment, the display control unit 54 changes the appearance of the warning light indicating the driving assistance function according to the operating status of the driving assistance function of the vehicle 12. Specifically, as a variation of the method, the display control unit 54 emphasizes the display of the warning light according to the operating status of the driving assistance function. Here, "emphasizing the display of the warning light" includes increasing brightness, changing the color (i.e., brightness, saturation, hue, etc.). As an example, the display control unit 54 displays the warning light in white when the driving assistance function is active, and in gray when the driving assistance function is in standby mode. Alternatively, the display control unit 54 displays the warning light in green when the driving assistance function is active, and in white when the driving assistance function is in standby mode. Furthermore, the display control unit 54 may also display the warning light in gray when the driving assistance function is disabled, and in amber when the driving assistance function is in an abnormal state.

[0074] (Screenshot displayed)

[0075] Hereinafter, a portion of the display screen displayed in the display area within the second display unit 26 of the first embodiment will be referred to. Figures 4A to 4D Let me explain. Figures 4A to 4D This diagram illustrates the warning lights that are displayed differently depending on the operating status of the driver assistance functions of vehicle 12. The display area within the second display unit 26 is an example of a "display area".

[0076] like Figures 4A to 4D As shown, the second display unit 26 displays a vehicle image M10 simulating the vehicle 12, a road surface image M11 simulating the driving lane of the vehicle 12, and a speed display M12 indicating the speed of the vehicle 12. Furthermore, the second display unit 26 displays a standby warning light T1 and an active warning light T2, which indicate the operating status of driver assistance functions. Moreover, the second display unit 26 has a fixed display area M1 for permanently displaying the standby warning light T1 and a vehicle area M2 for displaying the active warning light T2. The fixed display area M1 is an example of a "first area." The vehicle area M2 is an example of a "second area."

[0077] The vehicle image M10 is displayed such that the road surface image M11 is superimposed on the lower center of the display area within the second display unit 26. Furthermore, the speed display M12 is displayed approximately at the center of the vehicle image M10 in the left direction and in the vertical direction. In this embodiment, the left-right direction refers to the left-right direction of the display area of ​​the second display unit 26, and coincides with the left-right direction relative to the travel direction of the vehicle 12. Furthermore, the vertical direction refers to the vertical direction of the display area of ​​the second display unit 26.

[0078] The standby warning light T1 is a warning light indicating the standby state. Furthermore, the standby warning light T1 is displayed in a manner that moves between the fixed display area M1 and the vehicle area M2 when the operating state of the driver assistance function is changed. In this embodiment, the standby warning light T1 includes a standby warning light T1a indicating ACC is in standby mode, a standby warning light T1b indicating LTA is in standby mode, and a standby warning light T1c indicating LDA is in standby mode.

[0079] The start warning light T2 is a warning light indicating the start status, and it is highlighted compared to the standby warning light T1. Furthermore, the start warning light T2 is displayed in a counter-clockwise rotation from the near-front side to the depth side at the upper part of the vehicle image M10 in the vehicle area M2. Here, "near-front side" refers to the rear side of the vehicle shown in the vehicle image M10, and it aligns with the downward direction in the second display unit 26. Furthermore, "depth side" refers to the front side of the vehicle shown in the vehicle image M10, and it aligns with the upward direction in the second display unit 26. In addition, in this embodiment, the start warning light T2 is displayed larger the closer it is to the front and smaller the closer it is to the depth side. The start warning light T2 in this embodiment includes a start warning light T2a indicating ACC is active, a start warning light T2b indicating LTA is active, and a start warning light T2c indicating LDA is active.

[0080] The fixed display area M1 is an area that can fix the standby warning light T1 and the start warning light T2 in a row in the left-right direction. The fixed display area M1 is set at the upper left position of the display area within the second display unit 26. In addition, the warning light for the driving assistance function indicating the stop state may not be displayed in the fixed display area M1.

[0081] The vehicle area M2 is the area near the vehicle image M10. The vehicle area M2 is located at the lower center of the display area within the second display unit 26, and is situated around the periphery of the vehicle image M10. Within the vehicle area M2, the hazard warning light T2 is displayed in a circular rotation.

[0082] As an example, in this embodiment, when the LDA function is changed from a standby state to an active state, the vehicle display control device 10 can... Figure 4A The state shown is like Figure 4B The warning light is displayed by changing the state of the warning light on the second display unit 26 as shown. Furthermore, when the vehicle display control device 10 changes from the active state to the standby state after acquiring the LDA function, it can display the warning light from... Figure 4B The state shown is like Figure 4C The alarm light is displayed by changing the state of the alarm light on the second display unit 26 as shown.

[0083] like Figure 4A As shown, in the fixed display area M1, standby warning lights T1a, T1b, and T1c are fixedly displayed in a row in the left-right direction. Furthermore, standby warning light T1c is displayed in a manner that moves from the fixed display area M1 to the vehicle's area M2. Here, Figure 4A The solid line arrow marks indicate the direction and trajectory of the standby alarm light T1c's movement.

[0084] Thus, by displaying the standby warning lights T1a and T1b in the fixed display area M1, it is indicated that ACC and LTA are in standby mode. Furthermore, by displaying the standby warning light T1c in the fixed display area M1, and by displaying the standby warning light T1c separated from this area in a manner that moves to the vehicle area M2, it is indicated that LDA has changed from standby mode to active mode.

[0085] like Figure 4B As shown, in the fixed display area M1, the standby warning lights T1a and T1b, and the start warning light T2c are fixedly displayed in a row in the left-right direction. Furthermore, the start warning light T2c is displayed in a manner that rotates around the upper part of the vehicle image M10. Here, Figure 4B The solid arrow markings indicate the direction and trajectory of the alarm light T2c's circular rotation.

[0086] Thus, by making in Figure 4A The standby warning light T1c displayed in the image switches to the start warning light T2c to indicate that LDA has entered the start state. Furthermore, the start warning light T2c is displayed rotating in a circle at the top of the vehicle image M10 to indicate that LDA is in the start state.

[0087] like Figure 4CAs shown, in the fixed display area M1, standby warning lights T1a, T1b, and T1c are fixedly displayed in a row in the left-right direction. Furthermore, standby warning light T1c is displayed in a manner that moves from the vehicle's area M2 to the fixed display area M1. Here, Figure 4C The solid line arrow marks indicate the direction and trajectory of the standby alarm light T1c's movement.

[0088] Thus, by making in Figure 4B The start warning light T2c displayed in the display area switches to the standby warning light T1c to indicate that LDA has changed to a standby state. In addition, by displaying the standby warning light T1c in a manner that moves from the vehicle area M2 to the fixed display area M1, it indicates that LDA has changed from the start state to the standby state.

[0089] Furthermore, the vehicle display control device 10 of this embodiment displays images when multiple driver assistance functions are activated. Figure 4D The alarm light is displayed by changing the state of the alarm light on the second display unit 26 as shown.

[0090] like Figure 4D As shown, in the fixed display area M1, the activating warning lights T2a and T2b, and the standby warning light T1c are fixedly displayed in a row in the left-right direction. Furthermore, the activating warning lights T2a and T2b are displayed in a circular rotation around the upper part of the vehicle image M10. Figure 4D The solid arrow markings indicate the direction and trajectory of the circumduction of the warning lights T2a and T2b.

[0091] Thus, by displaying the start warning lights T2a and T2b in the fixed display area M1 and rotating them in a circle above the vehicle image M10, the status of ACC and LTA being activated is indicated. Furthermore, by displaying the standby warning light T1c in the fixed display area M1, the status of LDA being in standby mode is indicated.

[0092] In addition, although in the above Figures 4A to 4D In the description, an example of a display screen shown in the display area within the second display unit 26 was given. However, in this embodiment, the display screen can be displayed in at least one of the first display unit 24 and the second display unit 26. Furthermore, if the display area of ​​the first display unit 24 is smaller than the display area of ​​the second display unit 26, the first display unit 24 can be configured to display an image of a portion of the second display unit 26.

[0093] (flow chart)

[0094] Figure 5 This is a flowchart illustrating an example of the display processing flow according to the first embodiment. The display processing is executed by the CPU 30 of the ECU 28 reading a program from the ROM 32 or storage 36, expanding it in the RAM 34, and executing it. Furthermore, the display processing is executed by the CPU 30 functioning as a function state acquisition unit 52 and a display control unit 54. As an example, Figure 5 The processing shown is a process that is repeatedly executed during the driving of vehicle 12.

[0095] exist Figure 5 In step S100, the CPU 30 determines whether a change from the driving assistance function to the activated state has been detected. As an example, the CPU 30 determines whether a change from the standby state to the activated state of the vehicle 12's LDA has been detected. If the CPU 30 determines that a change from the driving assistance function to the activated state has been detected (step S100: Yes), it proceeds to step S101. If the CPU 30 determines that no change from the driving assistance function to the activated state has been detected (step S100: No), it proceeds to step S104.

[0096] In step S101, the CPU 30 displays a warning light indicating a detected driver assistance function in a manner that moves it from the fixed display area M1 to the vehicle area M2. As an example, the CPU 30 displays a standby warning light T1c indicating LDA in a manner that moves it from the fixed display area M1 to the vehicle area M2 (see reference). Figure 4A ).

[0097] In step S102, the CPU 30 prominently displays the warning light after it has been moved. As an example, when the standby warning light T1c, indicating LDA, moves into the vehicle's area M2, the CPU 30 switches the standby warning light T1c to the active warning light T2c for display (see [reference]). Figure 4B ).

[0098] In step S103, the CPU 30 displays the highlighted warning light in a manner that rotates in a circle around the upper part of the vehicle image M10. As an example, the CPU 30 displays the start warning light T2c, which indicates LDA, in a manner that rotates in a circle around the upper part of the vehicle image M10 (see reference). Figure 4B ).

[0099] In step S104, the CPU 30 determines whether a change from the driver assistance function to the standby state has been detected. As an example, the CPU 30 determines whether a change from the LDA of vehicle 12 to the standby state has been detected. If the CPU 30 determines that a change from the driver assistance function to the standby state has been detected (step S104: Yes), it proceeds to step S105. Conversely, if the CPU 30 determines that no change from the driver assistance function to the standby state has been detected (step S104: No), it terminates the display process.

[0100] In step S105, the CPU 30 displays a warning light indicating a detected driver assistance function in a manner that moves it from the vehicle's local area M2 to the fixed display area M1. As an example, the CPU 30 displays a warning light T2c indicating LDA activation in a manner that moves it from the vehicle's local area M2 to the fixed display area M1 (see reference). Figure 4C ).

[0101] In step S106, the CPU 30 ends the emphasis display of the moving warning light. As an example, when the LDA activation warning light T2c moves to the area outside the vehicle's area M2, the CPU 30 switches the activation warning light T2c to the standby warning light T1c for display (see reference). Figure 4C ).

[0102] In step S107, the CPU 30 clears the alarm light that has been moved to the fixed display area M1. As an example, the CPU 30 clears the standby alarm light T1c, which indicates LDA, displayed in a moving manner. Then, the CPU 30 ends the display process.

[0103] (Summary of the first implementation method)

[0104] The vehicle display control device 10 of the first embodiment displays a vehicle image M10 and a warning light indicating the operating status of a driving assistance function in the display area of ​​a second display unit provided around the driver's seat of the vehicle 12. Furthermore, it displays the warning light in the area surrounding the vehicle image M10 by moving the warning light indicating the driving assistance function according to changes in the operating status of the driving assistance function. Therefore, the vehicle display control device 10 of this embodiment enables the occupant to recognize changes in the operating status of the vehicle's functions.

[0105] When the driving assistance function is activated, the vehicle display control device 10 of the first embodiment displays a warning light indicating the driving assistance function by moving it from the fixed display area M1 to the vehicle area M2. Therefore, compared with the case where the warning light indicating the driving assistance function is not moved, the vehicle display control device 10 of this embodiment makes it easier for the occupants to recognize that the driving assistance function has been activated.

[0106] The vehicle display control device 10 of the first embodiment continuously displays a warning light indicating the driving assistance function in the vehicle area M2 during the period when the driving assistance function is activated. Therefore, according to the vehicle display control device 10 of this embodiment, since the warning light, which has moved from the fixed display area M1, is continuously displayed in the vehicle area M2, the occupants can easily recognize that the driving assistance function is activated.

[0107] The vehicle display control device 10 of the first embodiment displays warning lights for driver assistance functions that are in an active state in a circular rotation around the upper part of the vehicle image M10. Therefore, according to the vehicle display control device 10 of this embodiment, since the warning lights, after moving from the fixed display area M1, are continuously displayed while rotating around the upper part of the vehicle image M10, it is easier for the occupant to recognize each of the driver assistance functions that are in an active state.

[0108] In the first embodiment, the vehicle display control device 10 displays a warning light indicating the driving assistance function when the driving assistance function is in standby mode by moving the warning light from the vehicle area M2 to the fixed display area M1. Therefore, according to this embodiment, when the driving assistance function is activated, by returning the warning light displayed in the vehicle area M2 to the fixed display area M1, the occupant can easily recognize that the driving assistance function is in standby mode.

[0109] The vehicle display control device 10 of the first embodiment emphasizes the display of warning lights indicating the driving assistance function based on the operating status of the driving assistance function. Therefore, the vehicle display control device 10 of this embodiment enables occupants to distinguish changes in the operating status of the driving assistance function based on changes in the shape of the warning lights.

[0110] [Second Implementation]

[0111] The vehicle display control device 10 of the second embodiment displays the driver assistance function activation warning light T2, indicating the activation status, fixedly in the area indicating the activation status. Hereinafter, the differences from the first embodiment will be described. Furthermore, other structures are the same as in the embodiment described above, and therefore detailed descriptions are omitted.

[0112] In the second embodiment, after displaying a warning light indicating a driving assistance function in a manner that moves towards an area near the vehicle image M10, the display control unit 54 displays the warning light in a manner that draws it into the vehicle image M10. Furthermore, the display control unit 54 causes the warning light, which is displayed in a manner that draws it into the vehicle image M10, to be fixedly displayed in the area indicating the activated state during the period when the driving assistance function indicated by the warning light is in an activated state. An example of the area indicating the activated state is "the area surrounding the vehicle image."

[0113] (Screenshot displayed)

[0114] Hereinafter, a portion of the display screen of the second display unit 26 in the second embodiment will be referred to. Figures 6A to 6D Let me explain. Figures 6A to 6D This diagram illustrates the changes in warning lights that indicate the operating status of the driver assistance functions of vehicle 12.

[0115] like Figures 6A to 6D As shown, the second display unit 26 is provided with an activation area M3 that can permanently display the activation alarm light T2. The activation area M3 is an example of a "third area".

[0116] The start zone M3 is an area that can fix the start warning light T2 in a row in the left and right direction. The start zone M3 is set at the top of the speed display M12.

[0117] In this embodiment, the start warning light T2 is displayed in the vehicle area M2 and then absorbed into the vehicle image M10. Furthermore, the start warning light T2 is removed from the vehicle area M2 and displayed in the start area M3.

[0118] As an example, in this embodiment, when the LDA function is changed from a standby state to an active state, the vehicle display control device 10 can... Figure 6A The state shown is like Figure 6C The warning light is displayed by changing the state of the warning light on the second display unit 26 as shown. Furthermore, when the vehicle display control device 10 changes from the active state to the standby state after acquiring the LDA function, it displays the warning light from... Figure 6CThe state shown is like Figure 6D The alarm light is displayed by changing the state of the alarm light on the second display unit 26 as shown.

[0119] like Figure 6A As shown, in the fixed display area M1, the start warning lights T2a and T2b, and the standby warning light T1c are fixedly displayed in a row in the left-right direction. Furthermore, in the start area M3, the start warning lights T2a and T2b are fixedly displayed in a row in the left-right direction. Moreover, the standby warning light T1c is displayed in a manner that moves from the fixed display area M1 to the vehicle's own area M2. Here, Figure 6A The solid line arrow marks indicate the direction and trajectory of the standby alarm light T1c's movement.

[0120] Thus, by displaying the start warning lights T2a and T2b in the fixed display area M1 and the start area M3, the state that ACC and LTA are in the start state is indicated. Furthermore, by displaying the standby warning light T1c in the fixed display area M1, and then displaying the standby warning light T1c separately from there until it moves to the vehicle area M2, the state that LDA has changed from the standby state to the start state is indicated.

[0121] like Figure 6B As shown, in the fixed display area M1, the hazard warning lights T2a, T2b, and T2c are fixedly displayed in a row in the left-right direction. Furthermore, in the vehicle area M2, the hazard warning light T2c is displayed in a manner that it is drawn into the direction of the vehicle image M10. Here, Figure 6B The solid arrow markings indicate the direction and trajectory of the alarm light T2c being drawn in.

[0122] Thus, by making in Figure 6A The standby warning light T1c displayed in the image switches to the start warning light T2c to indicate that LDA has changed to the start state. Furthermore, by displaying the start warning light T2c in the vehicle area M2 and making it appear as if it is being drawn into the vehicle image M10, it indicates that the LDA of vehicle 12 has changed from the standby state to the start state.

[0123] like Figure 6C As shown, in the fixed display area M1, the activation alarm lights T2a, T2b, and T2c are fixedly displayed in a row in the left-right direction. Additionally, the activation area M3 also displays the activation alarm lights T2a, T2b, and T2c.

[0124] Thus, through Figure 6BThe start warning light T2c, which is displayed by being sucked in, is then extinguished, and the start warning light T2c is displayed in the start area M3 to indicate that LDA is in the start state.

[0125] like Figure 6D As shown, in the fixed display area M1, the activation alarm lights T2a and T2b, and the standby alarm light T1c are fixedly displayed in a row in the left-right direction. Additionally, the activation alarm lights T2a and T2b are displayed in the activation area M3.

[0126] Thus, by making in Figure 6C The startup alarm light T2c displayed in the startup area M3 is eliminated, and the startup alarm light T2c displayed in the fixed display area M1 is switched to the standby alarm light T1c to indicate that the LTA has changed from the startup state to the standby state.

[0127] (flow chart)

[0128] Figure 7 This is a flowchart illustrating an example of the display processing flow involved in the second embodiment.

[0129] because Figure 7 Steps S200 to S202 are the same as steps S100 to S102 (refer to...) Figure 5 The same process applies, so detailed explanations are omitted. Additionally, in step S200, if the CPU 30 determines that no change to the activation state of the driving assistance function has been detected (step S200: No), it proceeds to step S205.

[0130] In step S203, the CPU 30 displays the warning light, which is highlighted, in a manner that draws it into the vehicle image M10. As an example, the CPU 30 displays the activation warning light T2c, representing LDA, in a manner that draws it into the vehicle image M10 (see reference). Figure 6B ), and remove the warning light from vehicle zone M2.

[0131] In step S204, the CPU 30 displays the alarm light, which is then displayed in a suck-in manner, in the startup area M3. As an example, the CPU 30 permanently displays the startup alarm light T2c, indicating LDA, in the startup area M3 (see reference). Figure 6C ).

[0132] Since step S205 is related to step S104 (refer to...) Figure 5The same process applies, so detailed explanations are omitted. Additionally, if the CPU30 determines that no change from the driver assistance function to the standby state has been detected (step S205: No), the display process ends.

[0133] In step S206, CPU30 removes the warning light indicating the detected driver assistance function from the activation area M3. As an example, CPU30 removes the activation warning light T2c indicating LDA from the activation area M3 (see reference). Figure 6D Then, CPU30 finishes display processing.

[0134] (Summary of the second implementation method)

[0135] The vehicle display control device 10 of the second embodiment displays a warning light indicating a driving assistance function by incorporating it into the vehicle image M10. Therefore, according to the vehicle display control device 10 of this embodiment, since the warning light displayed in the incorporating manner and the vehicle image M10 are displayed in conjunction, the occupants can be given the impression that the driving assistance function indicated by the warning light of the vehicle 12 has been activated.

[0136] The vehicle display control device 10 of the second embodiment displays a warning light indicating the driving assistance function is activated in the activation area M3. Therefore, according to the vehicle display control device 10 of this embodiment, by displaying the warning light displayed in the vehicle area M2 in the activation area M3 in a fixed manner, the occupant can clearly recognize the driving assistance function in the activated state at a glance.

[0137] [Other implementation methods]

[0138] While the vehicle display control device 10 of the first embodiment acquires the operating status of the driver assistance functions of the vehicle 12, the operating status of the functions of the vehicle 12 acquired by the vehicle display control device 10 is not limited to this. The vehicle display control device 10 can also acquire the operating status of warning functions, which are operating functions of the vehicle 12. Warning functions include, for example, functions that display warnings as defined by safety standards, such as hydraulic warnings, seat belt not worn warnings, and lighting control system warnings to occupants. In addition, operating status includes normal status where functions are operating normally, abnormal status where functions are malfunctioning, and emergency status where an emergency check of functions is required. Moreover, the vehicle display control device 10 causes the warning lights indicating warning functions to change according to the operating status of the warning functions. Therefore, the vehicle display control device 10 according to this embodiment can display visual information that enables occupants to understand the changes in the operating status of the vehicle's warning functions. Furthermore, warnings are not limited to warnings defined by safety standards; any warning that reminds occupants to pay attention is acceptable.

[0139] While the vehicle display control device 10 of the first embodiment continuously displays the warning light T2 indicating the activation of the driving assistance function in the vehicle area M2 when the driving assistance function is activated, it is not limited to this. The vehicle display control device 10 of this embodiment can display the warning light in a manner that returns to the fixed display area M1 after displaying the warning light T2 in the vehicle area M2 for a predetermined time (e.g., 10 seconds). According to the vehicle display control device 10 of this embodiment, since the warning light indicating the activation of the driving assistance function is temporarily displayed in the vehicle area M2, it can attract the attention of the occupants.

[0140] Although the vehicle display control device 10 of the first embodiment displays the ignition warning light T2 in a counterclockwise rotation from the front to the depth side at the upper part of the vehicle image M10, the display method of the ignition warning light T2 is not limited to this. The vehicle display control device 10 of this embodiment can change the vertical rotation position, rotation direction, and tilt of the ignition warning light T2 during display. Therefore, according to the vehicle display control device 10 of this embodiment, the position in which the ignition warning light T2 is displayed in a circular rotation can be changed in accordance with the deformation of the display of the vehicle image M10 (e.g., vehicle model, size, etc.).

[0141] Although the vehicle display control device 10 of the first embodiment displays the warning light of the fixed display area M1 in the display area of ​​the second display unit 26, the method of displaying the warning light of the fixed display area M1 is not limited thereto. The vehicle display control device 10 of this embodiment can use a light (e.g., an LED light, a bulb light, etc.) to display the warning light of the fixed display area M1. For example, when the driver assistance function is activated, the vehicle display control device 10 illuminates the warning light in white, and when the driver assistance function is in standby mode, it turns off the warning light. Therefore, according to the vehicle display control device 10 of this embodiment, even if an adverse condition occurs in the display area of ​​the second display unit 26, the occupant can recognize the operating status of the driver assistance function based on the state of the light in the fixed display area M1.

[0142] While the vehicle display control device 10 of the second embodiment removes the warning light T2 indicating the driving assistance function from the activation area M3 when the driving assistance function is changed from an activated state to a standby state, it is not limited to this. The vehicle display control device 10 of this embodiment may also display the warning light T2, indicating the driving assistance function, by making it fly out of the vehicle image M10 when the driving assistance function is changed from an activated state to a standby state. Therefore, according to the vehicle display control device 10 of this embodiment, since the warning light displayed in a flying-out manner is displayed in conjunction with the vehicle image M10, the impression that the driving assistance function indicated by the warning light of the vehicle 12 has changed to a standby state can be left.

[0143] Although the vehicle display control device 10 of the second embodiment displays the warning light of the start-up area M3 in the display area of ​​the second display unit 26, the method of displaying the warning light of the start-up area M3 is not limited thereto. The vehicle display control device 10 of this embodiment can use a light to display the warning light of the start-up area M3. Therefore, according to the vehicle display control device 10 of this embodiment, even if an adverse condition occurs in the display area of ​​the second display unit 26, the occupant can recognize the working status of the driver assistance function based on the state of the light in the start-up area M3.

[0144] Although the first and second embodiments used driving assistance functions (1) ACC, (2) LDA, and (3) LTA as examples for description, the driving assistance functions of this embodiment are not limited thereto. The driving assistance functions of this embodiment include, for example, the following driving assistance functions.

[0145] (4) Automatic High Beam (AHB). This function is a system that normally keeps the high beams on to ensure visibility in the distance, and automatically switches the headlights between high and low when oncoming vehicles are detected. Use cases include nighttime driving.

[0146] (5) Emergency Driving Stop System (EDSS). This function determines whether the driver's state is normal or abnormal, and if an abnormal state is detected, notifies the outside of the vehicle and implements lane-keeping control. Furthermore, the scope of EDSS operation is envisioned to be expanded. While this function has historically been limited to highway applications, it is designed to be applicable to general roads as well. Additionally, although EDSS has historically only activated when an abnormal driver is detected during LTA operation, it is also planned to activate when the LTA is not operating. Application scenarios include driving on general roads or highways.

[0147] (6) Lane Change Assist (LCA). This function initiates lane change assistance through driver-activated turn signals. Furthermore, it provides steering assist and surrounding area monitoring during lane changes, and automatically turns off the turn signals after the lane change. A typical use case is highway driving.

[0148] (7) Panoramic View Monitor (PVM). This function displays an overhead viewpoint on a monitor using images captured by four cameras (front, rear, left, and right) to assist in driving scenarios with many blind spots. Furthermore, it effectively utilizes 3D image representation (indoor and outdoor viewpoints, perspective views, and surround views) to assist in a wider range of driving scenarios. The interface is designed to allow for free viewpoint manipulation, similar to that of a smart device. This enables peripheral confirmation that is not yet available in existing systems. Use cases include parking and reversing, exiting a parking space, and low-speed movement.

[0149] (8) Advanced Parking (AP). This function uses ultrasonic sonar and cameras at the front, rear, left, and right to detect the parking position. The driver provides instructions on the parking position displayed on the multimedia screen to automatically park the vehicle. It also assists with exiting the parking position. Automatic operation controls the accelerator, brakes, steering, and gear shifting. A path storage function is also available. This function assists in various environments by parking along a stored path. It provides safety assistance by referring to the same path as the driver. By exploring / detecting registered paths and providing usage suggestions to the driver, it increases initial usage and retention rates. Usage scenarios include parking and exiting a parking space.

[0150] (9) Blind Spot Monitoring (BSM) / BSM (Long). This function identifies vehicles present in the rear side area and assists in confirming the surrounding safety when changing lanes by illuminating / flashing the indicators on the door side mirrors. Furthermore, the BSM (Long) level can be set. Additionally, a lane-entry warning function is also envisioned. It detects bicycles and small motorcycles traveling to the side of the vehicle and applies a lane-entry warning when turning left or right. A possible use case is when changing lanes.

[0151] (10) Advanced Drive (AD). This function is a highly advanced driver assistance feature that allows for steering / acceleration / deceleration control under driver supervision in dedicated lanes (capable of non-interventional Level 2 autonomous driving). It can be expected to reduce driver load during long / long-distance driving. Furthermore, it assists with overtaking and lane changes to the destination based on vehicle navigation assistance using lane-level positioning via high-precision maps. Use cases include driving on dedicated lanes (and also on general highways in many foreign countries, such as North America).

[0152] (11) Trailer Driving Assist (T-ADAS). This function is a collective term for many functions related to trailer driving assistance. Among these functions are T-DRCC, T-PCS (Trailer Pre-Collision System), T-LDA, T-BSM, TBG (Trailer Backup Guide), and T-PVM. T-DRCC adjusts the acceleration / deceleration during ACC use to the most suitable acceleration / deceleration during towing, even when the vehicle weight changes during towing. T-PCS adjusts the timing of warning and braking control to the most suitable timing during towing, even when the vehicle weight changes during towing. T-LDA is a function that detects the possibility of lane / road departure even during towing and suppresses departure by operating the steering mechanism. T-BSM expands the detection area to the vicinity of the rear end of the towing vehicle's bumper when the trailer is towing, reducing the risk of collision during lane changes. TBG provides reverse assistance during trailer towing through steering assist. T-PVM is a PVM function used in trailer towing or specifically for trucks.

[0153] Hereinafter, examples of the display of the second display unit 26 when the various driving assistance functions described above are applied in the vehicle display control device 10 of this embodiment will be referred to. Figure 8 Let me explain.

[0154] like Figure 8 As shown, standby warning lights T1a to T1k are displayed in the fixed display area M1. In this embodiment, warning lights are provided corresponding to each of the aforementioned driver assistance functions. For example, standby warning light T1d corresponds to AHB, standby warning light T1e corresponds to EDSS, standby warning light T1f corresponds to LCA, standby warning light T1g corresponds to PVM, standby warning light T1h corresponds to AP, standby warning light T1i corresponds to BSM, standby warning light T1j corresponds to AD, and standby warning light T1k corresponds to T-ADAS. Furthermore, an activation warning light T2 corresponding to each driver assistance function is also provided. Therefore, the vehicle display control device 10 according to this embodiment enables the occupant to recognize the changes in the operating status of various driving assistance functions by moving the warning light according to the changes in the operating status of the driving assistance functions and switching between displaying the standby warning light T1 and the start warning light T2.

[0155] While the vehicle display control device 10 of the first and second embodiments displays a simulated vehicle image M10 and a road image M11 for viewing the vehicle 12 from a rearward oblique upward perspective at the center of the second display unit 26, it is not limited to this. The vehicle display control device 10 of this embodiment can display a simulated vehicle image M20 for viewing the vehicle 12 from a direct upward perspective and a surrounding image M21 indicating the surrounding conditions of the vehicle 12 at the center of the second display unit 26. For example, when the functions of PVM, AP, etc., are activated, the vehicle display control device 10 displays the vehicle image M20 and the surrounding image M21 on the second display unit 26. The surrounding image M21 is, for example, an actual image synthesized from images captured by four cameras (front, rear, left, and right). Alternatively, the surrounding image M21 can also be an image simulating the surrounding conditions of the vehicle 12. Hereinafter, an example of the display on the second display unit 26 when the PVM is changed from a standby state to an activated state will be referred to... Figure 9A as well as Figure 9B Let me explain.

[0156] against Figure 9A The example shown is for... Figure 4A The differences will be explained. Additionally, regarding other structures, they differ from those described above. Figure 4A Similarly, detailed explanations are omitted.

[0157] like Figure 9A As shown, in the fixed display area M1, the standby warning lights T1g and T1h are fixedly displayed in a row in the left-right direction. Furthermore, the standby warning light T1g is displayed in a manner that moves from the fixed display area M1 to the vehicle's area M2. Here, Figure 9A The solid line arrow marks indicate the direction and trajectory of the standby alarm light T1g's movement.

[0158] Thus, by displaying the standby warning lights T1g and T1h in the fixed display area M1, the standby status of the PVM and AP is indicated. Furthermore, by displaying the standby warning light T1g in the fixed display area M1, and then displaying the standby warning light T1g separately until it moves to the vehicle area M2, the PVM is indicated to have changed from a standby state to an active state.

[0159] like Figure 9B As shown, in the fixed display area M1, a start warning light T1g indicating that the PVM is activated is displayed. Additionally, an image of the vehicle M20, an image of the surrounding area M21, and a guide image GL showing guide lines for reversing while parked are also displayed.

[0160] Thus, by making in Figure 9A The standby warning light T1g is switched to the start warning light T2g to indicate that the PVM is in the start state. Furthermore, the vehicle image M10 and road image M11 are switched to the vehicle image M20 and surrounding image M21 to indicate that the PVM is in the start state.

[0161] Therefore, according to the vehicle display control device 10 of this embodiment, by displaying a bird's-eye view of the surroundings of the vehicle 12 on the second display unit 26, the occupants can be aware of the surroundings of the vehicle 12. Furthermore, the vehicle display control device 10 of this embodiment displays from... Figure 9A Towards Figure 9B During the transition, the ignition warning light T2g can be displayed either by rotating around the top of the vehicle image M10, or by being drawn into the vehicle image M10.

[0162] Furthermore, the structure of the vehicle display control device 10 described in the above embodiments is an example and can be modified according to the situation without departing from the main idea.

[0163] Furthermore, the process flow described in the above embodiments is also an example, and unnecessary steps can be deleted, new steps can be added, or the processing order can be replaced without departing from the main idea.

[0164] In addition, in the above embodiments, CPU refers to a processor in a broad sense, including general-purpose processors such as CPU (Central Processing Unit), dedicated processors such as GPU (Graphics Processing Unit), ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), and programmable logic devices.

[0165] Furthermore, the actions of the processor in the above embodiments can be performed not only by a single processor, but also by multiple processors located in physically separate positions working together. Moreover, the order of the processor's actions is not limited to the order described in the above embodiments and can be appropriately changed.

[0166] Furthermore, while the above embodiments have been described with the program pre-stored (installed) in storage, this is not a limitation. The program may also be provided on recording media such as CD-ROM (Compact Disc Read Only Memory), DVD-ROM (Digital Versatile Disc Read Only Memory), and USB (Universal Serial Bus) storage. Additionally, the program may be configured to be downloaded from an external device via a network. Moreover, this disclosure can be applied to programs and program products containing programs.
