[0003] [Patent Document 1] Patent No. 7048398 Summary of the Invention [Problem to be solved by the invention]

[0004] In the technology described in Patent Document 1, the recognized surroundings of the vehicle and the target trajectory of the vehicle are displayed on a display unit. Although there is technology that allows operation of the display area using a touch panel or the like, there is room for improvement in terms of enabling the state of the vehicle's operating functions (for example, driving assistance functions) to be changed by intuitive operation.

[0005] The disclosed technology aims to provide a vehicle display control device that can change the state of an operating function of the vehicle through intuitive operations on a display area. [Means for solving the problem]

[0006] The vehicular display control device according to claim 1 includes a display control unit that displays an image of the host vehicle that imitates the host vehicle and functional images that indicate operational functions of the host vehicle in a display area provided around a driver's seat of the host vehicle, and that moves the display of the functional images in response to an operation on the functional images, and a functional control unit that controls a state of the operational function corresponding to the operated functional image based on a positional relationship between the host vehicle image and the functional images. Therefore, the vehicle control device according to claim 1 allows the state of the operational functions of the host vehicle to be changed by an intuitive operation on the display area.

[0007] The vehicular display control device according to claim 2 is the vehicular display control device according to claim 1, wherein the display control unit displays the functional image corresponding to the disabled operation function in a first area that is an area that can be displayed when the operation function is disabled, and when the functional image is moved from the first area to a second area that is an area near the host vehicle image, the function control unit enables the operation function corresponding to the moved functional image. Therefore, according to the vehicular display control device according to claim 2, the operation function corresponding to the functional image that indicates a disabled state can be enabled by moving the functional image from the first area closer to the host vehicle image.

[0008] The vehicular display control device according to claim 3 is the vehicular display control device according to claim 1 or 2, wherein when a predetermined condition for changing the state of the operational function is not satisfied, the function control unit sets the state of the operational function to the state before the change, and the display control unit displays warning information indicating that the operational function is in the state before the change. Therefore, according to the vehicular display control device according to claim 3, when an attempt is made to change an operational function for which a predetermined condition is not satisfied, it is possible to notify an occupant that the operational function could not be changed.

[0009] The vehicular display control device according to claim 4 is the vehicular display control device according to any one of claims 1 to 3, wherein the display control unit displays the functional image corresponding to the enabled operation function in a third area that is an area that can be displayed when the operation function is enabled, and when the functional image is moved from the third area, the function control unit disables the operation function corresponding to the moved functional image. Therefore, according to the vehicular display control device according to claim 4, the operation corresponding to the functional image that indicates an enabled state can be disabled by removing the functional image from the third area.

[0010] The vehicular display control device according to claim 5 is the vehicular display control device according to any one of claims 1 to 4, which displays a list of the states of one or more of the operating functions based on an operation on a predetermined area around the host vehicle image. Therefore, the vehicular display control device according to claim 5 allows an occupant to recognize the states of the host vehicle's operating functions at a glance. [Effects of the Invention]

[0011] According to the disclosed technology, the state of the operating functions of the vehicle can be changed by intuitively operating the display area. [Brief explanation of the drawings]

[0013] A vehicle 12 to which a vehicle display control device 10 according to this embodiment is applied will be described with reference to the drawings. Note that the vehicle 12 according to this embodiment is equipped with a plurality of driving assistance functions, including a driving assistance function related to autonomous driving, as an example. The vehicle 12 is an example of a "host vehicle." The driving assistance function is an example of an "operation function." Note that the operation function may be any function related to the vehicle 12, such as a door lock function, a window opening / closing function, or the like, as long as it can be operated by an occupant of the vehicle 12.

[0014] The driving assistance functions provided in the vehicle 12 of this embodiment include various driving assistance functions, but this embodiment will be described taking the following driving assistance functions as examples. (1) Radar Cruise Control (ACC / DRCC: Adaptive Cruise Control / Dynamic Radar Cruise Control): This function is a driving assistance function that uses a camera and radar (monocular camera and millimeter-wave radar) included in the sensor group 42, which will be described later, to recognize a preceding vehicle and assist in following the preceding vehicle while maintaining a safe distance according to the vehicle speed. (2) Lane Tracing Assist (LTA). This function uses the system to provide some of the steering force required to keep the vehicle in the center of the same lane while under ACC control. It can be used, for example, when driving on a highway. Under ACC control is an example of a "predetermined condition."

[0015] As shown in FIG. 1, the vehicle display control device 10 of this embodiment includes an ECU (Electronic Control Unit) .

[0016] The ECU 28 includes a CPU (Central Processing Unit: processor) 30, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 34, a storage 36, and an input / output interface 38. Each component is connected to each other via an internal bus 39 so as to be able to communicate with each other.

[0017] The CPU 30 is a central processing unit that executes various programs and controls each part. That is, the CPU 30 reads programs from the ROM 32 or storage 36 and executes the programs using the RAM 34 as a work area. The CPU 30 also controls the above-mentioned components and performs various arithmetic processing in accordance with the programs recorded in the ROM 32 or storage 36.

[0018] The ROM 32 stores various programs and various data. The RAM 34 temporarily stores programs or data as a working area. The storage 36 is configured by an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and is a non-temporary recording medium that stores various programs including an operating system and various data. In this embodiment, the ROM 32 or the storage 36 stores a display program for performing display processing, etc. Furthermore, various input / output devices are connected to the input / output interface 38. For example, a touch panel (not shown) provided on the second display unit 26 described later is connected to the input / output interface 38.

[0019] A head-up display (HUD) device 23 and a meter 25 are connected to the ECU 28. The first display unit 24 is configured by a projection surface onto which the HUD device 23 projects. The second display unit 26 is a display displayed on the meter 25, which is located in front of the driver's seat on an instrument panel (not shown) provided in the front part of the passenger compartment of the vehicle 12. The first display unit 24 and the second display unit 26 are provided in positions visible to the driver. In this way, the vehicular display control device 10, the first display unit 24, and the second display unit 26 configure a vehicular display system.

[0020] Here, the ECU 28 is electrically connected to the autonomous driving ECU 40. Like the ECU 28, the autonomous driving ECU 40 is configured to include a CPU, a ROM, a RAM, a storage, an input / output interface, and the like, all of which are not shown.

[0021] The autonomous driving ECU 40 is connected to a group of sensors 42 that detects the current situation of the vehicle and a group of actuators 44 that control the traveling of the vehicle. The group of sensors 42 includes a plurality of sensors selected from various types of sensors, such as a camera, radar, LIDAR (Light Detection and Ranging or Laser Imaging Detection and Ranging), and a GPS (global positioning system) sensor. The camera captures images of the surroundings of the vehicle. The radar uses radio waves to detect the distance and direction of objects around the vehicle. The LIDAR uses laser light to detect the distance and direction of objects around the vehicle. The GPS sensor detects the current position of the vehicle. In addition to these, the group of sensors 42 is configured to include sensors that detect the state of the occupant. For example, the group of sensors 42 may be configured to include biological sensors that detect the occupant's heart rate, alertness, etc.

[0022] The actuator group 44 includes an acceleration / deceleration actuator that adjusts the acceleration / deceleration of the vehicle, and a steering actuator that drives the vehicle's steering device. The autonomous driving ECU 40 controls the operation of the actuator group 44 in accordance with the current situation of the vehicle detected by the sensor group 42, thereby performing autonomous driving of the vehicle. Note that a planned route indicating the route along which the vehicle is planned to travel is stored in a memory unit of the autonomous driving ECU 40, and the autonomous driving ECU 40 causes the vehicle to travel along the planned route stored in the memory unit.

[0023] An accelerator position sensor 46 and a steering sensor 48 are connected to the ECU 28. The accelerator position sensor 46 is a sensor that detects the position of an accelerator pedal (not shown) that is provided below the driver's seat. The steering sensor 48 is a sensor that detects the load applied to the steering wheel 16 by the occupant. That is, the steering sensor 48 of this embodiment is configured not to detect the load when the steering wheel 16 is operated by the autonomous driving ECU 40 during autonomous driving, but to detect the load when the occupant is operating the steering wheel 16.

[0024] The vehicular display control device 10 uses the above hardware resources to realize various functions. The functional configuration realized by the vehicular display control device 10 will be described with reference to FIG.

[0025] 2, the vehicle display control device 10 of this embodiment is configured to include, as functional components, a display control unit 52 and a function control unit 54. Each functional component is realized by the CPU 30 of the ECU 28 reading and executing a program.

[0026] The display control unit 52 has a function of displaying a moving telltale indicating the operation status of the driving assistance function in accordance with the detected gesture operation. For example, the display control unit 52 displays a moving telltale indicating the operation status of the driving assistance function of the vehicle 12 in accordance with a slide operation detected on a touch panel provided on the second display unit 26. The operation status specifically includes a stopped state in which the function is not activated, a standby state in which the function can be activated, and an activated state in which the function is activated. The standby state is an example of an "inactive" state. The activated state is an example of an "active" state. The gesture operation is not limited to a slide operation, but may be any gesture operation such as a single tap operation, a double tap operation, a pinch-in operation, or a pinch-out operation. Note that the gesture operation is not limited to one detected by a touch panel, but may also be an operation based on information detected by the sensor group 42 (e.g., image information indicating the movement of the occupant's fingers). Hereinafter, the telltale indicating the operation status of the driving assistance function of the vehicle 12 may also be simply referred to as a "telltale." Telltales are an example of "functional images."

[0027] The display control unit 52 also has a function of changing the manner of the host vehicle image when displaying it. For example, the display control unit 52 changes the size of the host vehicle image M10 (see FIG. 3(A) etc.) that resembles the vehicle 12 and displays it on the first display unit 24 and the second display unit 26. Note that the display control unit 52 may change not only the size of the host vehicle image M10, but also the color, decoration, type of parts (for example, bumper, side mirrors, etc.) and the like when displaying it.

[0028] The display control unit 52 has a function of displaying a warning image when the operating state of the driving assistance function cannot be changed. For example, when the driving assistance function cannot be set to an activated state, the display control unit 52 displays a warning image T3 (see FIG. 4(A)) on the first display unit 24 and the second display unit 26. Note that the display control unit 52 may also display the warning image T3 when the driving assistance function cannot be set to a standby state. The warning image T3 is an example of "warning information."

[0029] Furthermore, the display control unit 52 has a function of displaying a list of driving assistance functions in response to the detected gesture operation. For example, when a double-tap operation on a predetermined area of ​​the second display unit 26 is detected, the display control unit 52 causes the first display unit 24 and the second display unit 26 to display a list display M4 (see FIG. 4(B)).

[0030] The function control unit 54 has a function of controlling the operation state of the driving assistance function. For example, the function control unit 54 controls the operation state of the driving assistance function of the vehicle 12 via the autonomous driving ECU 40 by transmitting a signal to the autonomous driving ECU 40. Note that the function control unit 54 may also directly control the operation state of the driving assistance function of the vehicle 12. The function control unit 54 of this embodiment changes the operation state of the driving assistance function of the vehicle 12 depending on the positional relationship between the telltale and the host vehicle image M10. However, if a precondition is not met, the function control unit 54 does not change the operation state of the driving assistance function of the vehicle 12. Here, the precondition refers to the operation state of another function required to change the operation state of a certain function. For example, a precondition for turning the LTA into an activated state is that the ACC is activated, and a precondition for turning the ACC into a standby state is that the LTA is standby. For example, if the ACC is not activated, the function control unit 54 does not turn the LTA into an activated state. Furthermore, if the LTA is not in a standby state, the function control unit 54 does not turn the ACC into a standby state. The precondition is an example of a "predetermined condition." The function control unit 54 may change the control of the activation state of the activation function of the vehicle 12 based on the direction in which the telltale is located relative to the host vehicle image M10. For example, the function control unit 54 may change the activation state of the left door lock function of the vehicle 12 when a telltale indicating a door lock function approaches from the left of the host vehicle image M10.

[0031] A portion of the display screen displayed in the display area of ​​second display unit 26 of this embodiment will be described below with reference to Fig. 3 and Fig. 4. Fig. 3 and Fig. 4 are diagrams showing the display screen that changes and is displayed in response to a detected gesture operation. The display area of ​​second display unit 26 is an example of a "display area."

[0032] As shown in Figures 3(A) and 3(B), the second display unit 26 displays a host vehicle image M10 that resembles the vehicle 12, a road surface image M11 that resembles the lane the vehicle 12 is traveling in, and a speed display M12 that indicates the speed of the vehicle 12. The second display unit 26 also displays a standby telltale T1 that is a telltale indicating a standby state and an activation telltale T2 that is a telltale indicating an activated state. The second display unit 26 is configured with a fixed display area M1 in which the standby telltale T1 can be fixedly displayed, a host vehicle area M2 in which the activation telltale T2 can be displayed, and an activation area M3 in which the activation telltale T2 can be fixedly displayed. The fixed display area M1 is an example of a "first area." The host vehicle area M2 is an example of a "second area." The activation area M3 is an example of a "third area" and a "predetermined surrounding area."

[0033] The host vehicle image M10 is displayed superimposed on the road surface image M11 at a position below the center of the display area in the second display unit 26. The host vehicle image M10 in this embodiment includes a normal-sized host vehicle image M10N and a slightly larger-sized host vehicle image M10L. The speed display M12 is displayed to the left of the host vehicle image M10, at approximately the center in the vertical direction. The left-right direction in this embodiment is the left-right direction of the display area of ​​the second display unit 26, and coincides with the left-right direction with respect to the traveling direction of the vehicle 12. The up-down direction is the up-down direction of the display area of ​​the second display unit 26.

[0034] The standby telltale T1 is a telltale indicating a standby state, and is displayed at a lower brightness than the activation telltale T2. In this embodiment, the standby telltale T1 includes a standby telltale T1a indicating that the ACC is in a standby state, and a standby telltale T1b indicating that the LTA is in a standby state. In addition, the activation telltale T2 is a telltale indicating a startup state, and is displayed at a higher brightness than the standby telltale T1. In this embodiment, the activation telltale T2 includes a startup telltale T2a indicating that the ACC is in a startup state, and a startup telltale T2b indicating that the LTA is in a startup state.

[0035] The fixed display area M1 is an area where the standby telltale T1 and the activation telltale T2 can be displayed in a fixed line in the left-right direction. The fixed display area M1 is set in a position in the upper left direction of the display area in the second display unit 26. The host vehicle area M2 is an area near the host vehicle image M10. The host vehicle area M2 is set in a position in the lower center of the display area in the second display unit 26, around the host vehicle image M10. The area near the host vehicle image M10 is, for example, an area within a predetermined range from the host vehicle image M10. The activation area M3 is an area where the activation telltale T2 can be displayed in a fixed line in the left-right direction. The activation area M3 is set in a position above the speed display M12.

[0036] As shown in FIG. 3(A), a startup telltale T2a and a standby telltale T1b are displayed in fixed display region M1. Furthermore, startup telltale T2a is displayed in startup region M3. Then, in accordance with the detected slide operation, standby telltale T1b in fixed display region M1 is displayed as if it is moving to host vehicle region M2. Furthermore, inside host vehicle region M2, standby telltale T1b is switched to startup telltale T2b and displayed. Here, the solid arrow in FIG. 3(A) indicates the direction and trajectory of the detected slide operation.

[0037] In this way, the activation telltale T2a is displayed in the fixed display area M1 and the activation area M3, indicating that the ACC is activated. Furthermore, the standby telltale T1b is moved from the fixed display area M1 to the host vehicle area M2 and switched to the activation telltale T2b, indicating that the LTA is changing from the standby state to the activated state.

[0038] As shown in FIG. 3(B), activation telltales T2a and T2b are displayed in fixed display area M1. Furthermore, activation telltales T2a and T2b are displayed in activation area M3. Then, in accordance with the detected slide operation, activation telltale T2b in activation area M3 is displayed as if it is moving to an area outside activation area M3. Furthermore, outside activation area M3, activation telltale T2b is switched to and displayed as standby telltale T1b. Furthermore, host vehicle image M10N is switched to and displayed as a slightly larger host vehicle image M10L. Here, the solid arrow in FIG. 3(B) indicates the direction and trajectory of the detected slide operation.

[0039] In this way, the activation telltales T2a and T2b are displayed in both the fixed display area M1 and the activation area M3, indicating that the ACC and LTA are activated. Furthermore, the activation telltale T2b is moved from the activation area M3 and switched to the standby telltale T1b, indicating that the LTA will change from an activated state to a standby state. Furthermore, the display of the host vehicle image M10L indicates that the number of activated driving assistance functions has increased compared to the state in FIG. 3(A).

[0040] As shown in FIG. 4(A), standby telltales T1a and T1b are displayed in fixed display area M1. Furthermore, a warning image T3 indicating that the operating state of the driving assistance function could not be changed is displayed in host vehicle area M2. Then, after the standby telltale T1b in fixed display area M1 moves to host vehicle area M2 in accordance with the detected slide operation, the activation telltale T2b is displayed as if it is being repelled from host vehicle area M2. Here, the solid arrow in FIG. 4(A) indicates the direction and trajectory of the detected slide operation. Furthermore, the dashed arrow indicates the direction and trajectory of movement of the telltale that is displayed as if it is being repelled from host vehicle area M2.

[0041] In this way, the standby telltales T1a and T1b are displayed in the fixed display area M1, indicating that the ACC and LTA are in a standby state. In addition, the warning image T3 is displayed in the host vehicle area, and the activation telltale T2b is displayed as if it is being bounced out of the host vehicle area M2, indicating that the LTA could not be changed from a standby state to an activated state because the ACC is not activated.

[0042] 4(B), a list display M4 that displays a list of the driving assistance functions of the vehicle 12 is displayed in the left area of ​​the second display unit 26. The list display M4 is configured to include a name area M41 that displays the telltales and names of the driving assistance functions, a change button M42 that can change the operating state of each driving assistance function, and a close button M43 that can hide the list display M4.

[0043] Here, in the name area M41, a telltale indicating ACC and the name "ACC" are displayed in the first row, and a telltale indicating LTA and the name "LTA" are displayed in the second row. The change button M42 is displayed in the on state in the first row and in the off state in the second row. The close button M43 is displayed in the upper right corner of the list display M4. Furthermore, a startup telltale T2a and a standby telltale T1b are displayed in the fixed display area M1.

[0044] In this way, the telltale and name indicating ACC are displayed in the first row of the list display M4, the first row of the change button M42 is displayed in the ON state, and the activation telltale T2a is displayed in the fixed display area M1, indicating that ACC is activated. Also, the telltale and name indicating LTA are displayed in the second row of the list display M4, the second row of the change button M42 is displayed in the OFF state, and the standby telltale T1b is displayed in the fixed display area M1, indicating that LTA is in standby. Note that pressing a change button M42 may change the operating state of the driving assistance function corresponding to the pressed change button M42.

[0045] 3 and 4, an example of a display screen displayed in the display area of ​​second display unit 26 has been described, but in this embodiment, a display screen may be configured to be displayed on at least one of first display unit 24 and second display unit 26. Furthermore, if the display area of ​​first display unit 24 is smaller than the display area of ​​second display unit 26, first display unit 24 may be configured to display a part of the image of second display unit 26.

[0046] 5 is a flowchart showing an example of the flow of display processing according to this embodiment. The display processing is executed by the CPU 30 of the ECU 28 reading a program from the ROM 32 or the storage 36, expanding the program in the RAM 34, and executing it. The display processing is executed by the CPU 30 functioning as the display control unit 52 and the function control unit 54. The display processing shown in FIG. 5 is, for example, processing that is repeatedly executed while the vehicle 12 is traveling.

[0047] In step S100 of Fig. 5, the CPU 30 determines whether or not a slide operation from the fixed display area M1 to the telltale indicating the LTA has been detected. Specifically, the CPU 30 determines whether or not a slide operation (see Fig. 3(A)) from the fixed display area M1 to the host vehicle area M2 to the standby telltale T1b indicating the LTA has been detected. If the CPU 30 determines that a slide operation from the fixed display area M1 to the telltale indicating the LTA has been detected (step S100: YES), the CPU 30 proceeds to step S101. On the other hand, if the CPU 30 determines that a slide operation from the fixed display area M1 to the telltale indicating the LTA has not been detected (step S100: NO), the CPU 30 proceeds to step S104.

[0048] In step S101, the CPU 30 determines whether the ACC is activated (i.e., ACC control is in progress). If the CPU 30 determines that the ACC is activated (step S101: YES), the process proceeds to step S102. On the other hand, if the CPU 30 determines that the ACC is not activated (step S101: NO), the process proceeds to step S106.

[0049] In step S102, the CPU 30 changes the LTA to an active state. Specifically, the CPU 30 changes the LTA from a standby state to an active state.

[0050] In step S103, CPU 30 increases the size of host vehicle image M10 by one level and displays a telltale indicating LTA in the startup area. Specifically, CPU 30 switches host vehicle image M10N to host vehicle image M10L and displays startup telltale T2b indicating LTA in startup area M3. CPU 30 also switches standby telltale T1b indicating LTA displayed in fixed display area M1 to startup telltale T2b for display.

[0051] In step S104, the CPU 30 displays the telltale indicating the LTA in a flicking manner and displays the warning image T3 for a predetermined period of time. Specifically, the CPU 30 displays the activation telltale T2b indicating the LTA, which is displayed to move to the host vehicle area M2 in accordance with the occupant's sliding operation, in a flicking manner from the host vehicle area M2 (see FIG. 4(A)). Furthermore, the CPU 30 displays the warning image T3 for five seconds, for example (see FIG. 4(A)).

[0052] In step S105, CPU 30 determines whether or not a slide operation from activation region M3 to a telltale indicating LTA has been detected. Specifically, CPU 30 determines whether or not a slide operation from activation region M3 to an area outside activation region M3 to activation telltale T2b indicating LTA (see FIG. 3(B)) has been detected. If CPU 30 determines that a slide operation from activation region M3 to a telltale indicating LTA has been detected (step S105: YES), CPU 30 proceeds to step S106. On the other hand, if CPU 30 determines that a slide operation from activation region M3 to a telltale indicating LTA has not been detected (step S105: NO), CPU 30 proceeds to step S108.

[0053] In step S106, the CPU 30 changes the LTA to a standby state. Specifically, the CPU 30 changes the LTA from an active state to a standby state.

[0054] In step S107, CPU 30 reduces the size of host vehicle image M10 by one level and erases the telltale indicating LTA from startup region M3. Specifically, CPU 30 switches host vehicle image M10L to host vehicle image M10N and erases startup telltale T2b indicating LTA from startup region M3. CPU 30 also switches startup telltale T2b indicating LTA in fixed display region M1 to standby telltale T1b for display.

[0055] In step S108, the CPU 30 determines whether a double tap operation on the startup area M3 has been detected. If the CPU 30 determines that a double tap operation on the startup area M3 has been detected (step S108: YES), the CPU 30 proceeds to step S109. On the other hand, if the CPU 30 determines that a double tap operation on the startup area M3 has not been detected (step S108: NO), the CPU 30 ends the display process.

[0056] In step S109, the CPU 30 displays a list of the operating states of the driving assistance functions. Specifically, the CPU 30 displays a list display M4 (see FIG. 4(B)). Then, the CPU 30 ends the display process. The CPU 30 may hide the list of operating states by detecting that the close button M43 included in the displayed list of operating states has been pressed.

[0057] The vehicular display control device 10 of this embodiment displays a host vehicle image M10 and telltales indicating the operating status of driving assistance functions in a display area of ​​a second display unit provided around the driver's seat of the vehicle 12, moves the display of the telltale in accordance with a slide operation on the telltale, and changes the operating status of the driving assistance function corresponding to the telltale based on the positional relationship between the host vehicle image M10 and the telltale. Therefore, the vehicular display control device 10 of this embodiment makes it possible to change the status of the operating functions of the host vehicle through intuitive operations on the display area.

[0058] The vehicular display control device 10 of this embodiment displays a telltale indicating a driving assistance function in a standby state in the fixed display region M1, and when the telltale is moved from the fixed display region M1 to the host vehicle region M2, the driving assistance function corresponding to the telltale is activated. Therefore, according to the vehicular display control device 10 of this embodiment, the driving assistance function corresponding to the standby telltale T1 can be changed to an activated state by moving the standby telltale T1 from the fixed display region M1 closer to the host vehicle image M10.

[0059] When the ACC is not activated, the vehicular display control device 10 of this embodiment keeps the LTA in a standby state and displays a warning image T3 in the host vehicle area M2, even if the telltale indicating the LTA is moved from the fixed display area M1 to the host vehicle area M2. Therefore, according to the vehicular display control device 10 of this embodiment, when an attempt is made to activate a driving assistance function whose prerequisites are not satisfied, it is possible to notify the occupant that the driving assistance function could not be activated.

[0060] The vehicular display control device 10 of this embodiment displays a telltale corresponding to an activated driving assistance function in the startup region M3, and when the telltale is moved from the startup region M3 to a region other than the host vehicle region M2, changes the driving assistance function corresponding to the moved telltale to a standby state. Therefore, according to the vehicular display control device 10 of this embodiment, the driving assistance function corresponding to the activation telltale T2 can be changed to a standby state by an operation to move the activation telltale T2 from the startup region M3.

[0061] The vehicular display control device 10 of this embodiment displays the operation states of multiple driving assistance functions in a list in response to a double tap operation on the startup area M3. Therefore, the vehicular display control device 10 of this embodiment allows the occupant to recognize the operation states of the driving assistance functions of the vehicle 12 at a glance.

[0062] [Other embodiments] In the above-described embodiment, the driving assistance functions (1) ACC and (2) LTA have been described as examples, but the driving assistance functions of this embodiment are not limited to these. The driving assistance functions of this embodiment include, for example, the following driving assistance functions. (3) Lane Departure Alert (LDA): When the system determines that the vehicle is likely to depart from its lane, it notifies the driver by displaying a warning, sounding a buzzer, or vibrating the steering wheel, urging them to take action to avoid the lane departure. It also assists in preventing lane departure by applying steering force and displaying a warning. (4) Automatic High Beam (AHB). This function normally turns on the high beams to ensure long-distance visibility, and when an oncoming vehicle approaches, it detects the light from a vehicle ahead and automatically switches the headlights between high and low. It can be used, for example, when driving at night. (5) Emergency Driving Stop System (EDSS). This function determines whether the driver's condition is normal or abnormal, and if it is determined to be abnormal, it controls the vehicle to stop within the lane while alerting people outside the vehicle. It is also expected that the range of situations in which EDSS can be activated will be expanded. Previously, it was only applicable to expressways, but this will be expanded to include general roads as well. Also, previously, EDSS was activated only when a driver abnormality was detected while LTA was in operation, but now EDSS can be activated even when LTA is not in operation. It can be used, for example, when driving on general roads or expressways. (6) Lane Change Assist (LCA). This function initiates lane change assistance when the driver activates the turn signal. It also provides steering assistance and periphery monitoring assistance during lane changes, and automatically turns off the turn signal after the lane change. It can be used, for example, when driving on a highway. (7) Panoramic View Monitor (PVM). This function displays an overhead view on the monitor using images captured by four cameras (front, rear, left and right), supporting driving situations with many blind spots. In addition, it utilizes three-dimensional image representation (indoor and outdoor views, slip-through images, and in-between images) to support a wider range of driving situations. It can be designed with an interface that allows for free viewpoint control, just like a smart device. This makes it possible to support checking surroundings that were out of reach with conventional systems. Examples of usage scenarios include when reversing into parking, reversing out of a parking space, and when moving at low speeds. (8) Advanced Park (AP). This function uses ultrasonic sonar and front, rear, left and right cameras to detect parking positions, and the driver can indicate the parking position displayed on the multimedia screen, allowing the vehicle to automatically park in the garage and assist with exiting the parking space. Automatic operation involves operating the accelerator, brake, steering and shift. The system may also have a route memory function. The route memory function provides assistance adapted to various environments by parking along a memorized route. By following the same route as the driver, the system provides reliable assistance. The system searches for and detects registered routes and makes usage suggestions to the driver, thereby improving first-time usage and continuation rates. Usage scenarios include when parking and exiting the parking space. (9) Blind Spot Monitor (BSM) / BSM(Long). This function recognizes vehicles in the rearward and lateral areas and assists the driver in checking the surrounding safety when changing lanes by turning on or flashing the door mirror indicators. The level of BSM(Long) can also be set. A hit-and-run warning function is also expected. It detects bicycles and small motorcycles traveling on the side of the vehicle and issues a hit-and-run warning when turning right or left. An example of a use scenario is when changing lanes. (10) Advanced Drive (AD). This is an advanced driving assistance function that controls steering and acceleration / deceleration under driver supervision on expressways (allowing for hands-off automated driving level 2). It is expected to reduce the burden on the driver during long and long-distance driving. It also uses high-precision maps to identify the vehicle's position at lane level, providing assistance with overtaking and lane changes toward the destination in cooperation with the car navigation system. It can be used, for example, when driving on expressways (although in some countries, such as North America, it is also expected to be used on general highways). (11) Trailer Driving Assist (T-ADAS). This function is a collective term for various functions related to trailer driving assistance. These functions include T-DRCC, T-PCS (Trailer Pre-Collision System), T-LDA, T-BSM, TBG (Trailer Backup Guide), and T-PVM. T-DRCC optimizes acceleration / deceleration when using ACC to tow even when the vehicle weight changes during towing. T-PCS optimizes the timing of warnings and brake control to tow even when the vehicle weight changes during towing. T-LDA detects the possibility of lane / road departure even during towing and controls the steering to prevent departure. T-BSM expands its detection area to the rear edge of the towing vehicle's bumper when towing a trailer, reducing the risk of collision when changing lanes. TBG provides steering assist to assist in reversing when towing a trailer. T-PVM is a PVM function specifically designed for use when towing a trailer or in a truck.

[0063] Hereinafter, a display example of the second display unit 26 in a case where the above-described various driving assistance functions are applied to the vehicle display control device 10 of this embodiment will be described with reference to FIG.

[0064] As shown in FIG. 6, standby telltales T1a to T1k are displayed in the fixed display area M1.
