In addition, during the operation of the driving support control, the display of the support state display image corresponding to the operating driving support control is continuously displayed on the display device, and the minimum display preset by the operating driving support control is set in advance. If it is determined that the operation has been completed before the time has elapsed, the display of the support state display image corresponding to the operating driving support control is performed until the minimum display time has elapsed, while the driver's driving operator Operation-responsive driving assistance control, which is driving assistance control that operates according to the operation of the vehicle, and disturbance-responsive driving assistance control, which is driving assistance control that operates according to changes in the behavior of the vehicle roof caused by disturbance, are activated simultaneously. If it is determined, the display control for displaying the support state display image corresponding to the operation support driving support control is performed in preference to the disturbance support driving support control .

  According to the present invention, the support state display image for notifying the driver of the operation state of the driving support device is continuously displayed while the driving support control is operating, and the driving support control is performed before the minimum display time has elapsed. Even if is finished, it continues to be displayed until the minimum display time has elapsed. Thereby, even when the operating state of the driving support control changes in a short time, it becomes possible to improve the recognizability of the display information related to the operating state of the driver.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIGS. 1-17 is a figure which shows embodiment of the display control apparatus for vehicles which concerns on 1st Embodiment of this invention, and the display control method for vehicles. (Constitution)
FIG. 1 is a conceptual diagram showing a model of an automobile V to which the vehicle display control apparatus according to this embodiment is applied.
The automobile V of this embodiment is equipped with an SBW (steer-by-wire) system. As shown in FIG. 1, the automobile V includes a steering wheel 1 that can be steered by a driver, left and right front wheels (steered wheels) 11 </ b> R and 11 </ b> L, and a steering shaft 2.
The steering wheel 1 is provided so as to be mechanically separable from the left and right front wheels 11R and 11L. The steering wheel 1 is connected to the steering shaft 2.

The automobile V further includes a steering angle sensor 3, a reaction force motor 4, and a steering torque sensor 5. The steering angle sensor 3, the reaction force motor 4, and the steering torque sensor 5 are provided on the steering shaft 2.
The steering angle sensor 3 detects the steering angle θs of the steering wheel 1 and is composed of an encoder or the like.
The reaction force motor 4 is for applying a steering reaction force to the steering wheel 1 by applying a torque to the steering shaft 2. Here, the steering reaction force is a reaction force acting in a direction opposite to the operation direction in which the driver steers the steering wheel 1. The reaction force motor 4 is constituted by a brushless motor or the like, and is driven according to a reaction force motor drive current output from an SBW controller 80 described later.

The steering torque sensor 5 detects the steering torque T transmitted from the steering wheel 1 to the steering wheel 2. The steering torque sensor 5 is configured to detect the steering torque T by detecting the torsional angular displacement of the torsion bar with a potentiometer.
The automobile V further includes a clutch 6, a pinion shaft 7, a steering motor 8, a steering motor angle sensor 9, a pinion gear 12, a rack shaft 13, a tie rod 14, a knuckle arm 15, and an SBW controller. 80.

The clutch 6 is interposed between the steering wheel 1 and the steered wheels 11R and 11L, and is switched to a released state or an engaged state in accordance with a clutch command (clutch command current) from the SBW controller 80.
The clutch 6 is in a released state in a normal state, and is in an engaged state when some abnormality (for example, abnormality in the steering reaction force system) occurs in the SBW system. In a state where the abnormality occurs and the clutch 6 is engaged, steering assist control (hereinafter referred to as EPS control) for applying a steering assist force for reducing the driver's steering burden to the steering system is performed.

The clutch 6 is also in the engaged state when the driver is in the end contact state where the driver steers the steering wheel 1 to the vicinity of the cut limit. When the clutch 6 is engaged in the end contact state, end contact control for giving the driver a feeling of end contact is performed.
In the released state of the clutch 6, the torque transmission path between the steering wheel 1 and the steered wheels 11R and 11L is mechanically separated, so that the steering operation of the steering wheel 1 is not transmitted to the steered wheels 11R and 11L. On the other hand, when the clutch 6 is engaged, the torque transmission path between the steering wheel 1 and the steered wheels 11R and 11L is mechanically coupled, so that the steering operation of the steering wheel 1 is transmitted to the steered wheels 11R and 11L. Become.

One end of the pinion shaft 7 is connected to the clutch 6, and a pinion gear 12 is provided at the other end. The pinion gear 12 meshes with a rack gear provided between both end portions of the rack shaft 13.
Both ends of the rack shaft 13 are connected to the steered wheels 11R and 11L via tie rods 14 and knuckle arms 15, respectively. That is, the steered wheels 11R and 11L are steered via the tie rod 14 and the knuckle arm 15 by changing the rack shaft 13 in the vehicle width direction according to the rotation of the pinion gear 12, and the traveling direction of the vehicle V is changed. It is possible.

Further, the steering motor 8 is configured by a brushless motor or the like, similarly to the reaction force motor 4, and is driven according to the steering motor drive current output by the SBW controller 80. The steered motor 8 is driven according to the steered motor drive current to output steered torque for steered steered wheels 11R and 11L.
A steered output gear 8 a formed using a pinion gear 12 is provided on the output shaft tip side of the steered motor 8. The steered output gear 8 a meshes with a rack gear provided between both end portions of the rack shaft 13. That is, the steered wheels 11R and 11L can be steered according to the rotation of the steered output gear 8a.

Further, the steered motor 8 is provided with a steered motor angle sensor 9. The steered motor angle sensor 9 detects the rotation angle of the steered motor 8. The turning angle θr of the steered wheels 11R and 11L is uniquely determined by the rotation angle of the steered output gear 8a and the gear ratio between the rack gear of the rack shaft 13 and the steered output gear 8a. Therefore, in the present embodiment, the turning angle θr of the steered wheels 11R and 11L is obtained from the rotation angle of the steered motor 8.
The SBW controller 80 inputs the steering angle θs of the steering wheel 1 detected by the steering angle sensor 3, the steering torque T detected by the steering torque sensor 5, and the turning angle θr detected by the turning motor angle sensor 9. . In addition, the SBW controller 80 receives the vehicle speed Vd and the yaw rate γ from a controller (not shown) of another system.

  In the released state of the clutch 6, the SBW controller 80 drives and controls the steered motor 8 according to the steering state of the steering wheel 1 to steer the steered wheels 11 </ b> R and 11 </ b> L. Thereby, the turning angle θr of the steered wheels 11R and 11L coincides with the turning command angle according to the steering state. At the same time, the SBW controller 80 drives and controls the reaction force motor 6 according to the steered state of the steered wheels 11R and 11L, and applies a steering reaction force to the steering wheel 1. As a result, a steering reaction force simulating a road surface reaction force is applied to the steering wheel 1. In this way, the SBW controller 80 performs steer-by-wire control (hereinafter referred to as SBW control).

In the state where the clutch 6 is engaged in the end contact state, the SBW controller 80 turns the steering angle so as to fix the turning angle at a predetermined turning angle as end contact control for giving the driver a feeling of end contact. Angle fixed control is performed. The predetermined turning angle is, for example, a rack end angle. The end contact control is ended at the timing when the driver performs the switchback operation of the steering wheel 1. After the end contact control is completed, the normal SBW control is resumed.
The automobile V further includes a meter device 20, a display control controller 30, a driving support device 40, and a communication network 50.
Furthermore, the automobile V includes a brake pedal 16 that can be depressed by the driver, and a brake operation detection device 17 that detects a depression amount Bd of the brake pedal 16.

(Driving support device 40)
The driving support device 40 includes a plurality of control systems (not shown) that perform various driving support controls. The driving support device 40 performs various driving support controls by controlling the braking / driving force of the automobile 1, controlling the gear ratio of the transmission (CVT), and controlling the SBW system.
Furthermore, the driving support device 40 generates an operation flag indicating the operating state of various driving support controls, and transmits the generated operation flag to the display controller 30 via the communication network 50. Here, the operation flag is set for each type of driving support control. Each operation flag is a flag that is ON (signal is high level) during operation of the driving support control and is OFF (signal is low level) during the non-operation of the driving support control.

In the present embodiment, the driving support device 40 performs the following driving support control (1) to (6). In addition, it is good also as a structure which implements other driving assistance control, such as not only the following six types (1)-(6) but inter-vehicle maintenance control.
(1) ATC (Active Trace Control)
(2) AEB (Active Engine Brake)
(3) ARC (Active Ride Control)
(4) HSA (Hill Start Assist)
(5) HDC (Hill Descent Control)
(6) SMB (Side Magic Bumper)

The ATC provides brake and engine output to each wheel so as to reduce the delay of the yaw rate of the vehicle V with respect to the steering in accordance with the steering state of the driver and the turning state of the vehicle V detected based on a plurality of sensor detection values. It is the driving support control to be controlled.
The AEB adds a deceleration by controlling the gear ratio of the transmission according to the driver's steering state and the driving state of the vehicle V detected based on a plurality of sensor detection values, and the driving load when driving the corner ( This is driving support control that reduces a driver's pedal switching operation.
ARC is driving support control that improves the convergence of the movement of the shed after overcoming the unevenness that is a relatively large input of the vehicle V by brake control.
The HSA is driving support control that prevents the vehicle V from moving backward when switching from the brake pedal to the accelerator pedal by holding the brake pressure for several seconds (for example, about 2 seconds) when starting on a slope.

The HDC is capable of setting a steep downhill that cannot be decelerated by engine braking alone or a downhill on a slippery road such as a snowy road at a constant vehicle speed (4 km / h to 15 km / h). This is driving support control that performs braking / driving control so that it can be lowered.
SMB is driving support control that improves traveling stability with respect to the steering angle of the vehicle V. The SMB recognizes the lane of the road ahead by an in-vehicle camera (not shown) installed on the upper part of the rear mirror of the automobile V so that the travel line can be accurately traced with a small steering angle correction. When a deviation is detected between the traveling direction of the automobile V and the lane, the SBW system is controlled, the tire angle is corrected so as to reduce the deviation, and a reaction force is applied to the steering. . Since SMB can reduce the change even if the course of the car changes due to, for example, a crosswind or a saddle, it is possible to suppress the driver's correction rudder.

The driving support device 40 generates an operation flag corresponding to each of the driving support controls (1) to (6), and transmits the generated operating flag to the display controller 30 via the communication network 50.
Specifically, as shown in FIG. 1, the operation flag SMB indicating the operation state of the SMB, the operation flag ATC indicating the operation state of the ATC, the operation flag AEB indicating the operation state of the AEB, and the operation state of the HSA are illustrated. An operation flag HSA, an operation flag HDC indicating the operation state of the HDC, and an operation flag ARC indicating the operation state of the ARC are generated. Then, the generated operation flags SMB, ATC, AEB, HSA, HDC and ARC are transmitted to the display controller 30 via the communication network 50.

  The communication network 50 is a network that adopts a CAN (Controller Area Network) communication protocol in the present embodiment. In the CAN communication protocol, various controllers are connected in a line-type connection configuration, and data communication is performed by multi-master bus access. In addition, not only a CAN communication protocol but the structure which employ | adopted other communication protocols, such as LIN (local interconnect network) and FlexRay (flex ray), for example is good. In the present embodiment, the SBW system employs the FlexRay communication protocol.

The brake operation detection device 17 supplies the detected brake pedal operation amount to a VDC system (not shown) that is one of the control systems provided in the driving support device 40.
Here, the VDC system is a system that performs braking / driving control (stability control) to improve the stability of the vehicle V by sensing the side slip of the front and rear wheels and controlling the braking force and engine output of each wheel. It is. In the present embodiment, the VDC system generates BHS (Brake Hold State) information indicating the depression state of the brake pedal 16 of the driver based on the supplied brake pedal operation amount. Then, the generated BHS information is supplied to the display controller 30 via the communication network 50. The BHS information may be obtained from another system.

Further, in the present embodiment, display control of the HSA indicator lamp of the indicator 24b is performed at the time of operation of the HSA which is one of the driving support controls.

Hereinafter, a specific configuration of the display controller 30 will be described with reference to FIG.
FIG. 4 is a block diagram illustrating an example of a specific configuration of the display controller 30.
As shown in FIG. 4, the display controller 30 includes a display control ECU 300, an effect information storage memory 302, and a display time measurement timer 304.
The display control ECU 300 includes an input processing unit 300A and a display control unit 300B. The display control unit 300B includes a display time delay processing unit 300C and an output signal processing unit 300D.
The input processing unit 300 </ b> A receives operation flags for various driving support controls from the driving support device 40 via the communication network 50. Furthermore, the input processing unit 300 </ b> A receives the steering angle θs from the steering angle sensor 3 via the communication network 50. Then, the input processing unit 300A inputs the received operation flag to the display time delay processing unit 300C.

Further, the input processing unit 300A performs a process of determining the steering direction based on the received steering angle θs and a preset steering angle threshold value. Specifically, the received absolute value of the steering angle θs is compared with a preset steering angle threshold value. For example, if it is determined that the absolute value of the positive steering angle θs is greater than or equal to the steering angle threshold value, right steering is performed. Judge that it was broken. On the other hand, if it is determined that the absolute value of the negative steering angle θs is greater than or equal to the steering angle threshold, it is determined that left steering has been performed. When it is determined that the absolute value of the steering angle θs is less than the steering angle threshold, it is determined that the automobile V is in a straight traveling state (a state where the steering wheel 1 is in the neutral position). Then, information on the steering direction based on the determination result (hereinafter referred to as steering direction information) is input to the output signal processing unit 300D.
Here, the steering direction information includes information on the left steering flag and the right steering flag.
The left steering flag is a flag indicating that left steering is being performed when the signal is in the ON state (for example, the signal level is high), and left steering when the signal is in the OFF state (for example, the signal level is low). This is a flag indicating that no is performed.

On the other hand, the right steering flag is a flag indicating that right steering is performed when the signal is in the ON state (for example, the signal level is high), and when the signal is in the OFF state (for example, the signal level is low). This flag indicates that right steering is not being performed.
Further, when both the left steering flag and the right steering flag are OFF, it indicates that the steering wheel 1 is in the neutral position.
Further, the input processing unit 300A receives the BHS information from the driving support device 40, the operation flag HSA, and the vehicle speed Vd from another system via the communication network 50. Then, based on the received BHS information, the operation flag HSA, and the vehicle speed Vd, an HSA effect display command including an HSA support state display image display command and an HSA indicator lamp display command is transmitted via the communication network 50. Transmit to the meter device 20.

  The display time delay processing unit 300C determines the operation state of the driving support control based on the input operation flag. When it is determined that at least one of the five types of driving support control excluding the HSA has been activated, the minimum value set in advance for the driving support control determined to have been activated from the effect information storage memory 302. Information on display time (hereinafter referred to as minimum display time information) is acquired. In the present embodiment, the minimum display time can be set for each type of driving support control.

  Here, the minimum display time is a time required to continuously display the support state display image on the display screen of the liquid crystal display device 26 in order to improve the recognition of the display content of the driver. is there. In the present embodiment, basically, the support state display image is continuously displayed during the operation of the driving support control. On the other hand, when the driving support control ends before the minimum display time preset for the driving support control elapses, the display of the support state display image is continued until the minimum display time elapses. To do.

  However, in this embodiment, when another driving assistance control is activated while a certain driving assistance control is in operation, the display time of the assistance state display image for the driving assistance control that has been operating first has passed the minimum display time. Even if not, the display of the support state display image for the driving support control that has been operated later is immediately executed. In other words, the display control with priority is given to the later generation.

The minimum display time information is information in which information indicating the type of driving support control is associated with a constant (for example, a count value of a timer) indicating the minimum display time corresponding to the type.
The display time delay processing unit 300C inputs the minimum display time information acquired from the effect information storage memory 302 and the supplied operation flag to the output signal processing unit 300D.
Based on the input minimum display time information and the operation flag, and the input steering direction information, the output signal processing unit 300D receives from the effect information storage memory 302 the support state display image corresponding to the corresponding driving support control. Read the display pattern information. Then, based on the read display pattern information and the count value of the display time measurement timer 304, an effect display command is generated, and the generated effect display command is transmitted to the meter device 20 via the communication network 50.

Here, the effect display command is command information including a display start command for various support state display images, a display switching command, a display end command, a display start command for the HSA indicator lamp, a display end command, and the like.
When the output signal processing unit 300 </ b> D determines that the operation flag has been turned on, the output signal processing unit 300 </ b> D transmits a display start command for the support state display image of the corresponding driving support control to the meter device 20 via the communication network 50. Further, after the display start command is transmitted, the display time measuring timer 304 is started to count, and the display time of the support state display image is measured.

Then, the output signal processing unit 300D determines the display end timing of the currently displayed support state display image based on the count value of the display time measurement timer 304.
Specifically, when the output signal processing unit 300D determines that the operation flag is in the OFF state (all the operation flags are in the OFF state) and the display time of the support state display image has passed the minimum display time, the display end timing is reached. Judge that there is.

Further, when the output signal processing unit 300D determines that the operation flag is in the OFF state (all the operation flags are in the OFF state) after the display time of the currently displayed support state display image has passed the minimum display time, the display is performed. It is determined that it is the end timing.
When the output signal processing unit 300 </ b> D determines that it is the display end timing, the output signal processing unit 300 </ b> D transmits a display end command to the meter device 20 via the communication network 50. That is, the output signal processing unit 300D determines that there is no driving support control that is operating, and causes the liquid crystal display device 26 to display a default image.

On the other hand, when the output signal processing unit 300D determines that the operation flag of the other driving support control is in the ON state before the display time of the currently displayed support state display image passes the minimum display time, the display switching is performed. The command is transmitted to the meter device 20 via the communication network 50.
Here, the display switching command is a display command for switching the currently displayed assist state display image to another assist state display image for driving support control in which the operation flag is turned on.

In the present embodiment, for driving support control with a clear operation scene, first, a support state display image (hereinafter referred to as a control intervention display image) to be displayed when it is determined that the driving support control has intervened is prepared in advance. Yes. Furthermore, an assistance state display image (hereinafter referred to as a scene-specific effect image) that is displayed by switching to a control intervention display image when it is determined that a preset operation scene is reached is prepared in advance. That is, these images are stored in advance in the effect image storage memory 29 of the meter device 20.
Specifically, the driving assistance control ATC and AEB have a clear scene in which the driving assistance control operates such as during the turning operation of the vehicle V (however, the operation assistance control is not limited to the turning operation). In the present embodiment, with respect to the driving support control ATC and AEB, a display image at the time of control intervention and a scene-specific effect image each corresponding to the steering direction (left steering, right steering) indicated by the steering direction information are provided in advance. It is stored in the storage memory 29.

  When the output signal processing unit 300D determines that the ATC or AEB is in the operating state based on the acquired operation flag ATC or AEB, the output signal processing unit 300D reads the display pattern information of the driving support control ATC or AEB from the effect information storage memory 302. Then, when the driving support control ATC or AEB determines that the intervention state (the operation state and the steering wheel 1 is in the neutral position) based on the read display pattern information and the acquired steering direction information, display of the control intervention display image starts. Generate directives. Then, the generated display start command is transmitted to the meter device 20 via the communication network 50.

  On the other hand, the output signal processing unit 300D is operating in a scene in which the driving support control ATC or AEB is set in advance based on the operation flag ATC or AEB and the steering direction information (in the operating state and during left steering or right steering). ), A display switching command to a scene-specific effect image corresponding to left steering or right steering is generated. Then, the generated display switching command is transmitted to the meter device 20 via the communication network 50. In the present embodiment, the scene-specific effect image is displayed only during a period in which left steering or right steering is performed. That is, even if the minimum display time has not elapsed since the display of the scene-specific effect image, the output signal processing unit 300D switches to the display image at the time of control intervention when the left steering or the right steering is completed. Display control is performed as follows. However, the operation flag ATC or AEB is in the OFF state until the total display time when the display image at the time of control intervention is first displayed and the display of the effect image for each scene is sandwiched between the minimum display time. However, display control is performed so that the display image is continuously displayed during control intervention.

The effect information storage memory 302 is a memory for storing the minimum display time information of various driving support controls and the display pattern information of the support state display images corresponding to the various driving support controls. In the present embodiment, the effect information storage memory 302 stores the minimum display time information of the driving support control ATC, AEB, ARC, SMB, and HDC. In addition, the effect information storage memory 302 stores display pattern information of support information display images for driving support control ATC, AEB, ARC, SMB, HDC, and HSA.
The display time measuring timer 304 is a timer counter that resets a count value in response to a reset command from the output signal processing unit 300D and starts counting in response to a count start command from the output signal processing unit 300D. Then, the display time measuring timer 304 inputs the counted value to the output signal processing unit 300D.

(Support status display image for HDC)
Next, based on FIG. 11, an assistance state display image displayed when the driving assistance control HDC is activated will be described. FIG. 11 is a diagram illustrating an example of the effect image 261HDC, which is an HDC support state display image.
The effect image 261HDC shown in FIG. 11 is a support state display image displayed when the operation flag HDC is in the ON state. Note that the driving support control HDC operates, for example, by turning on a dedicated switch (hereinafter referred to as an HDC switch) after fixing the vehicle V in a four-wheel drive state.

As shown in FIG. 11, the effect image 261HDC includes a mesh image 261g, a vehicle image 261i, wheel images 263SFL and 263SBL, and a downhill display line 267.

  Note that the driving support control ATC, AEB, ARC, and SMB are generated in such a manner that the vehicle V has a relatively high vehicle speed, the vehicle V is turning, or the vehicle V has a large unevenness. The driving load is relatively large, such as overtaking. Therefore, in such a situation, it is difficult for the driver to gaze at the display screen 260 of the liquid crystal display device 26 and to recognize detailed display contents. Therefore, in the present embodiment, for the driving support control ATC, AEB, ARC, and SMB with relatively high driving load, the vehicle image is arranged on the mesh-like planar image and the vehicle is looked down from the upper rear side. The support status display image of the composition was displayed. In addition, when the driving support control ATC, AEB, ARC, and SMB are operated, the mesh image portion around the vehicle image is displayed in a light-emitting manner.

I made it. Accordingly, the driver can recognize what kind of driving support control is activated by instantaneous line-of-sight movement and peripheral visual field without gazing at the display screen 260 of the liquid crystal display device 26. Become.

  On the other hand, the driving support control HSA and HDC are operated at a relatively low vehicle speed when the vehicle V is stopped in the middle of a steep uphill or on a downhill or snowy road where the vehicle V is steep. The driving load is relatively small, such as when driving. Therefore, in such a situation, it is relatively easy for the driver to recognize the display contents by looking at the display screen 260 of the liquid crystal display device 26. Therefore, in the present embodiment, when the driving support control HSA and HDC having a relatively small driving load are in operation, the vehicle image of the viewpoint when the vehicle is viewed from the side is displayed, and the operation state of the driving support control is displayed in the vehicle. Notification was made by light emission display and blinking display of the tire part of the wheel image in the image. As a result, the driver can recognize the relatively detailed operation status of the driving support control from the display content of the liquid crystal display device 26. In the present embodiment, the vehicle image portion of the effect image 261HSA has a shape similar to the indicator lamp 240HSA. This makes it easier for the driver to recognize that the driving support control HSA is operating when viewing the effect image 261HSA.

(Operation)

Is read. Then, based on the read display pattern information, a display start command X of an assistance state display image X (hereinafter referred to as an effect image X) corresponding to the driving assistance control X is generated. Further, the output signal processing unit 300 </ b> D transmits the generated display start command X to the meter device 20 via the communication network 50. On the other hand, the output signal processing unit 300D outputs a count operation start command to the display time measurement timer 304, and starts the count operation (display time measurement) by the display time measurement timer 304.

When the meter control controller 28 of the meter device 20 receives the display start command X from the output signal processing unit 300D, the meter control controller 28 reads information on the effect image X corresponding to the received display start command X from the effect image storage memory 29. . Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal X of an image to be displayed on the display screen 260 is generated based on the read information of the effect image X and the acquired various information, and the generated image display signal X is input to the liquid crystal display device 26. In addition, since various contents displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D change depending on time and circumstances, the image display on the display screen 260 is set in advance. Update at intervals.
Based on the input image display signal X, the liquid crystal display device 26 displays the effect image X on the display screen 260 as shown in (2) in FIG.

  In the example shown in (1) in FIG. 12, the operation time tox of the driving support control X is longer than the minimum display time tminx. Therefore, the output signal processing unit 300D does not end the display of the effect image X even when the count value of the display time measuring timer 304 exceeds the minimum display time tminx, and shows (1) and (2) in FIG. In this way, display control is performed so that the effect image X is continuously displayed until the operation flag X is in the OFF state. Specifically, when the output signal processing unit 300D determines that the input operation flag X is in the OFF state, the output signal processing unit 300D generates a display end command for the effect image X. Then, the generated display end instruction is transmitted to the meter device 20 via the communication network 50.

When the meter controller 28 of the meter device 20 receives the display end command from the output signal processing unit 300D, the meter controller 28 reads information on the default image 261DF from the effect image storage memory 29. Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal DF of an image to be displayed on the display screen 260 is generated based on the read information of the default image 261DF and the acquired various information, and the generated image display signal DF is input to the liquid crystal display device 26.
The liquid crystal display device 26 displays a default image 261DF on the display screen 260 based on the input image display signal DF.

Next, as shown in FIG. 12 (3), an operation example in the case where the operation time tox of the driving support control X is shorter than the minimum display time tminx will be described. In this case, even if the output signal processing unit 300D determines that the operation flag X input from the display time delay processing unit 300C is in the OFF state, as shown in (4) in FIG. Display control is performed so that the effect image X is continuously displayed until the time tminx is reached or greater.
That is, when the output signal processing unit 300D determines that the count value of the display time measuring timer 304 has reached the minimum display time tminx or more, the output signal processing unit 300D generates an effect image X display end command. Then, the generated display end instruction is transmitted to the meter device 20 via the communication network 50.

Next, as shown in (5) and (6) in FIG. 12, an operation example in the case where the driving support control B is operated later while the driving support control A is operating will be described. In the present embodiment, the driving assistance control A is any one of driving assistance control ATC, AEB, ARC, SMB, and HDC. In the present embodiment, the driving support control B is any one of the driving support controls ATC, AEB, ARC, SMB, and HDC different from the driving support control A.
As shown in (5) and (6) in FIG. 12, when the driving assistance control B is activated while the driving assistance control A is in operation, the display time delay processing unit 300C operates the operation flag A input from the input processing unit 300A. It is determined that the operation flag B is in the ON state while it is determined that is in the ON state.
The display time delay processing unit 300C reads the minimum display time tminB corresponding to the driving support control B from the effect information storage memory 302. Then, the read minimum display time tminB and the input operation flag are input to the output signal processing unit 300D.

  When the output signal processing unit 300D determines that the operation flag B is in the ON state while determining that the operation flag A is in the ON state based on the input operation flag, the output information processing unit 300D changes the effect information storage memory 302 to the driving support control B. Read the corresponding display pattern information. Then, based on the read display pattern information, a display switching command B to the effect image B corresponding to the driving support control B is generated. Further, the output signal processing unit 300 </ b> D transmits the generated display switching command B to the meter device 20 via the communication network 50. On the other hand, the output signal processing unit 300D outputs a reset command to the display time measurement timer 304 to reset the count value, and subsequently outputs a count operation start command to perform the count operation by the display time measurement timer 304. Start.

On the other hand, when receiving the display switching command B from the output signal processing unit 300D, the meter controller 28 of the meter device 20 reads information on the effect image B corresponding to the received display switching command B from the effect image storage memory 29. . Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal B of an image to be displayed on the display screen 260 is generated based on the read information of the effect image B and the acquired various information, and the generated image display signal B is input to the liquid crystal display device 26.
Based on the input image display signal B, the liquid crystal display device 26 displays the effect image B instead of the effect image A currently being displayed, as indicated by (8) in FIG.

  Further, as shown in (7) in FIG. 12, the operation time toB of the driving support control B is shorter than the minimum display time tminB. Therefore, even if the output signal processing unit 300D determines that the operation flag B input from the display time delay processing unit 300C is in the OFF state, the count value is the minimum display time as shown in (7) in FIG. Display control is performed so that the effect image B is continuously displayed until the value becomes equal to or greater than the value indicating tminB.

[Display control operation during operation of driving support control ATC or AEB]
Next, a display control operation when the driving support control ATC or AEB is activated will be described based on FIGS. 5 to 7, 13, and 14. FIG. 13 is a time chart for explaining an example of the display control operation when the driving support control ATC or AEB is activated. FIG. 14 is a diagram illustrating an example of a traveling scene in which the driving support control ATC or AEB is activated. In FIGS. 13 and 14, times t2 and t4 indicate the same time.
As shown in FIG. 13, it is assumed that the driving support control ATC or AEB is activated and the operation flag ATC or AEB is turned on at time t1.
In this case, the display time delay processing unit 300C reads the minimum display time information (here, the minimum display time tminA) corresponding to the driving support control ATC or AEB from the effect information storage memory 302. Then, the read minimum display time tminA and the input operation flag are input to the output signal processing unit 300D.

  When the output signal processing unit 300D determines that the operation flag ATC or AEB is in the ON state based on the operation flag input from the display time delay processing unit 300C, the output signal processing unit 300D corresponds to the driving support control ATC or AEB from the effect information storage memory 302. Read display pattern information. Then, based on the read display pattern information and the steering direction information (left steering flag and right steering flag) input from the input processing unit 300A, an instruction image display start command corresponding to the driving support control ATC or AEB is generated. To do.

Specifically, at time t1, since both the left steering flag and the right steering flag are in the OFF state, the output signal processing unit 300D generates a display start command for the control intervention display image 261IN.

Thus, at time t2, the left steering flag is turned on. When the left steering flag is turned on, the output signal processing unit 300D generates a display switching command to the left steering effect image 261LC. Then, the generated display switching command is transmitted to the meter device 20 via the communication network 50.
As a result, the left steering effect image 261LC shown in FIG. 7A is displayed on the display screen 260 of the liquid crystal display device 26 in place of the control intervention display image 261IN currently being displayed.

At time t4, the right steering flag is turned on. When the right steering flag is turned on, the output signal processing unit 300D generates a display switching command to the right steering effect image 261RC. Then, the generated display switching command is transmitted to the meter device 20 via the communication network 50.
As a result, a right steering effect image 261RC shown in FIG. 7B is displayed on the display screen 260 of the liquid crystal display device 26 instead of the control intervention display image 261IN currently displayed.

Thereafter, when the driver steers the steering wheel 1 to the neutral position and the left steering flag is turned off at time t5 as shown in FIG. 13, the output signal processing unit 300D displays the control intervention display image. A display switching command to 261IN is generated. Then, the generated display switching command is transmitted to the meter device 20 via the communication network 50.

[Display control operation during operation of the driving support control HSA]
Next, based on FIG.16 and FIG.17, the display control operation | movement at the time of driving assistance control HSA act | operating is demonstrated. FIG. 16 is a diagram illustrating an example of temporal changes in the vehicle speed Vd, the brake pedal operation amount Bd, the brake fluid pressure, and the operation flag HSA in the operation scene of the driving support control HSA. FIG. 17 is a diagram showing an example of the transition of the display content of the display screen 260 and the transition of the lighting state of the HSA indicator lamp 240HSA with respect to the transition of the driving state of the vehicle V and the pedal operation state of the driver in the operation scene of the driving support control HSA. It is.

  As shown in FIG. 16, when the driver depresses the brake pedal 16 at time t1 while the vehicle V is traveling uphill (detected by an inclination sensor or the like), the depression state of the brake pedal 16 from the driving support device 40 is changed. BHS information shown is transmitted to the display controller 30 via the communication network 50. On the other hand, as shown in FIG. 16, when the brake pedal 16 is depressed, the brake fluid pressure rises and the brake operates. As a result, the vehicle speed Vd decreases.

  As shown in FIG. 16, when the brake pedal 16 is depressed and the vehicle speed Vd continues to decrease from time t1 to time t2, the operation flag HSA is turned off. Therefore, the input processing unit 300A determines that the driving support control HSA is inactive. In addition, the other driving support control is also deactivated here, and the output signal processing unit 300D performs display control processing of the default image 261DF. Thereby, as shown in the liquid crystal display screen column corresponding to the braking state column in FIG. 17, the default image 261DF is displayed on the display screen 260 of the liquid crystal display device 26. In addition, since the operation flag HSA is turned off, the HSA indicator lamp 240HSA is turned off as shown in the indicator display content column corresponding to the braking state column in FIG.

  Next, as shown in FIG. 16, when the vehicle speed Vd becomes 0 at time t3 with the brake pedal 16 depressed, at time t4 after elapse of a preset time (for example, about 1 [s]). The operation flag HSA is turned on. That is, the driving support device 40 transmits the operation flag HSA in the ON state and other operation flags in the OFF state to the display controller 30 via the communication network 50.

  Thus, the input processing unit 300A determines that the operation flag HSA has been turned on based on the received operation flag. In addition, the input processing unit 300A determines that the brake pedal 16 has been depressed based on the received BHS information. Thereby, the input processing unit 300A reads the display pattern information corresponding to the driving support control HSA from the effect information storage memory 302. Then, based on the read display pattern information, a display start command HSA (S) of the effect image 261HSA (S) of the driving support control HSA and a lighting display command of the HSA indicator lamp 240HSA are generated. Further, the input processing unit 300 </ b> A transmits the HSA effect display command including the generated display start command HSA (S) and the lighting display command to the meter device 20 via the communication network 50.

  On the other hand, the meter controller 28 of the meter device 20 receives the HSA effect display command including the display start command HSA (S) and the lighting display command from the input processing unit 300A. The meter controller 28 reads out information on the effect image 261HSA (S) corresponding to the display start command HSA (S) from the effect image storage memory 29 based on the received effect display command for HSA. Furthermore, the meter controller 28 sends various information to be displayed on the first display area 260A, the second display area 260B, and the fourth display area 260D of the display screen 260 from other controllers and instruments via the communication network 50. get. Then, an image display signal HSA (S) of an image to be displayed on the display screen 260 is generated based on the read information of the effect image HSA (S) and the acquired various information, and the generated image display signal HSA (S) is liquid crystal. Input to the display device 26. In parallel with this, the meter controller 28 inputs a lighting display command of the indicator lamp 240HSA to the indicator 24b of the second meter 24.

  Thereby, as shown in the liquid crystal display screen column corresponding to the vehicle stop state column in FIG. 17, the effect image 261HSA (S) is displayed on the display screen 260 of the liquid crystal display device 26. That is, the effect image 261HSA (S) in which the tire portions of the wheel images 263SFL and 263SBL are lit is displayed. In addition, as shown in the indicator display content column corresponding to the vehicle stop state column in FIG. 17, the indicator lamp 240HSA is turned on.

  Next, as shown in FIG. 16, when the driver lifts his / her foot from the brake pedal 16 at time t <b> 4 while the vehicle V is stopped on the uphill by the driver's braking, the brake fluid pressure of the driving support control HSA is set. The holding operation is started. As a result, during the period from time t4 to time t5 (for example, a maximum of 2 [s]), the brake fluid pressure is maintained and the stop state of the automobile V is maintained. Further, BHS information indicating that the brake pedal 16 is in the released state is transmitted from the driving support device 40 to the display controller 30 via the communication network 50.

  Based on the received operation flag HSA and BHS information, the input processing unit 300A determines that the brake pedal 16 has been released while the driving support control HSA is operating. Thereby, the input processing unit 300A generates a display start command HSA (O) of the effect image 261HSA (O) and a blinking display command of the indicator lamp 240HSA. Further, the input processing unit 300 </ b> A transmits the HSA effect display command including the generated display start command HSA (O) and the blinking display command to the meter device 20 via the communication network 50.

  On the other hand, the meter controller 28 of the meter device 20 receives the HSA effect display command including the display start command HSA (O) and the blinking display command from the input processing unit 300A. The meter controller 28 reads out the information of the effect image 261HSA (O) corresponding to the display start command HSA (O) from the effect image storage memory 29 based on the received effect display command for HSA. Furthermore, the meter controller 28 sends various information to be displayed on the first display area 260A, the second display area 260B, and the fourth display area 260D of the display screen 260 from other controllers and instruments via the communication network 50. get. Then, an image display signal HSA (O) of an image to be displayed on the display screen 260 is generated based on the read information of the effect image HSA (O) and the acquired various information, and the generated image display signal HSA (O) is liquid crystal. Input to the display device 26. In parallel with this, the meter controller 28 inputs a blink display command of the indicator lamp 240HSA to the indicator 24b of the second meter 24.

  As a result, the effect image 261HSA (O) is displayed on the display screen 260 of the liquid crystal display device 26 as shown in the liquid crystal display screen column corresponding to the brake fluid pressure holding state column in FIG. That is, in the effect image 261HSA (O), the tire portions of the wheel images 263SFL and 263SBL are displayed in a blinking manner. In addition, as shown in the indicator display content column corresponding to the brake fluid pressure holding state column in FIG. 17, the indicator lamp 240HSA is blinked.

Subsequently, as shown in FIG. 16, when the driver depresses an accelerator pedal (not shown) at time t5, the driving support control HSA is deactivated and the brake fluid pressure becomes zero. That is, the operation flag HSA is turned off, and the operation flag HSA in the off state and other operation flags in the off state are transmitted from the driving support device 40 to the display controller 30 via the communication network 50. . Thereby, the input processing unit 300A determines that the driving support control HSA is inactive. Further, the output signal processing unit 300D determines that all the operation flags are in the OFF state, and performs display control processing for the default image 261DF. Accordingly, as shown in the liquid crystal display screen column corresponding to the vehicle start state column in FIG. 17, the default image 261DF is displayed on the display screen 260 of the liquid crystal display device 26. In addition, since the operation flag HSA is turned off, the indicator lamp 240HSA is turned off as shown in the indicator display content column corresponding to the vehicle start state column in FIG.
Here, in the present embodiment, the function for determining the operation state of the driving support control based on the operation flag of the display controller 30 corresponds to the operation state determination unit. The display function of the support state display image of the display controller 30 corresponds to the display control unit.

(Effect of 1st Embodiment)
If it is this embodiment, it will become possible to show the effect described below.
(1) The display controller 30 detects the operating state of the driving support control performed by the in-vehicle driving support device 40. A liquid crystal display provided in the meter panel 21 of the meter device 20 displays a support state display image, which is an image having a configuration in which the vehicle image 261b is superimposed on the mesh image 261a, which is a mesh-like planar image. Display on the device 26. When the display control controller 30 determines that the driving support control is activated, the display control controller 30 performs display control to change the display mode of the mesh image 261a of the support state display image displayed on the liquid crystal display device 26 to a preset display mode.

  The driver is notified of the operation of the driving support device 40 by changing the display mode of the mesh image 261a. That is, since the display mode of the mesh image 261a, which can be said to be the background part, is changed instead of the fine parts of the vehicle image 261b, the driver can move the gaze instantaneously and the surrounding area without paying attention to the display content. It is possible to capture changes in display contents depending on the field of view. Thus, even when the driving load is large, it is possible to accurately notify the driver that the driving support control is operating without making the driver feel bothered.

(2) The vehicle image 261b is an image of a viewpoint looking down at the vehicle from the upper rear side of the vehicle.
The mesh image 261a extends in the perspective direction with the vehicle front-rear direction of the vehicle image 261b as the perspective direction, and has a shape in which the width in the direction orthogonal to the perspective direction increases toward the near side and the width decreases toward the far side. It was.
This allows the vehicle to travel farther on the mesh image. For example, the mesh image can be displayed in a display mode that looks like a road, such as deforming the mesh image into a curved shape in the turning direction of the vehicle. It becomes. Therefore, even when the driving load is relatively large, it is possible to accurately notify the driver that the driving support control is operating without making the driver feel more bothersome.

(3) If the display controller 30 determines that the driving support control has been activated, the display color of the mesh image 261a within the distance range set in advance from the vehicle image 261b of the support state display image is set in advance. Display control to be changed to
In other words, because the driver is informed that the driving support control is operating by changing the display color of the mesh image part, the driver can move the gaze instantaneously and It is possible to easily grasp changes in display contents depending on the field of view. Thus, the driver can easily recognize that the driving support control is operating without paying attention to the display content.

(4) The display controller 30 determines whether or not the driving support control (ATC, AEB) that is activated during the turning operation of the vehicle V is activated. If it is determined by this determination that it has been activated, the shape of the mesh image 261a of the support state display image displayed on the liquid crystal display device 26 is a curve shape that turns in the steering direction based on the steering angle θs detected by the steering angle sensor 3 (left Display control to change to a curved mesh image 261LC and a right curved mesh image 261RC) is performed.
That is, for driving support control with a clear operation scene such as during the turning operation of the vehicle V, the mesh image portion is changed to a shape that matches the operation scene in addition to the change of the display color around the vehicle image. Thus, the driver can more easily catch the change in the display content by instantaneous line-of-sight movement and peripheral visual field without paying attention to the display content. Therefore, the driver can more easily recognize that the driving support control is operating without paying attention to the display content.

(5) While the driving control (ATC, AEB) that is activated during the turning operation of the vehicle V is in operation, the display controller 30 displays a wheel-shaped image (wheel on the wheel position in the vehicle image 261b of the assistance state display image. Images 263FL, 263FR, 263BL, and 263BR) are superimposed and displayed. The display control controller 30 performs display control for displaying the wheel images 263FL, 263FR, 263BL, and 263BR in a color that provides a preset display effect of light emission.

  In other words, after the driving support control (ATC or AEB) that operates during the turning operation of the vehicle V intervenes, the wheel images 263FL, 263FR, 263BL, and 263BR are displayed with four-wheel light emission (the control intervention display image 261IN is displayed). I made it. As a result, in a situation where the driving load is relatively small before the vehicle V reaches the curved road, the driver can recognize that the control is intervening by visually recognizing the display content displayed on the four wheels. Is possible. After that, in a situation where the driving load is relatively large such as during a turning operation, the mesh image is displayed in a deformed manner and a light emission display. It is possible to easily detect changes in display contents according to the peripheral visual field. Therefore, the driver can more easily recognize that the driving support control is operating without paying attention to the display content.

(6) When the display controller 30 determines that the driving support control (SMB) for improving the running stability with respect to the steering angle of the vehicle V is activated, the mesh image 261a of the support state display image displayed on the liquid crystal display device 26. The shape is changed to a half-pipe shape in which walls in the direction orthogonal to the perspective direction of the mesh image 261a are lifted to form walls surrounding the left and right side surfaces of the vehicle image 261b (mesh image 261h). The display controller 30 divides an image portion within a preset distance range from the vehicle image 261b of the mesh image 261h into a plurality of regions in a direction orthogonal to the perspective direction. The display controller 30 divides the plurality of partitioned areas (left effect display areas AL1 to AL4, right effect display areas RL1 to RL4) in order from the partitioned area closer to the vehicle image 261b toward the further separated area. Display control for changing the current display color to another preset color is performed.
That is, an effect display in which walls are gradually formed on both sides of the vehicle image is performed by animation display by changing the display color. This makes it possible for the driver to easily grasp changes in the display contents according to the peripheral visual field without paying attention to the display contents, and to easily recognize what kind of driving support control has been activated. Become.

(7) The display control controller 30 performs display control to change the display color of the mesh image portion within the distance range set in advance from the vehicle image 261b to a display color that provides a preset display effect of light emission.
In other words, the image portion within a predetermined distance range from the vehicle image of the mesh image is changed to a color that produces a display effect that appears to emit light (for example, a color with high brightness or high brightness compared to the color of other regions). I did it. As a result, the driver can easily grasp the change in the display contents according to the peripheral visual field without paying attention to the display contents, so that the driver assistance control can be easily grasped. .

(8) When the display controller 30 determines that the driving support control 40 is in operation, an image for displaying a support state, which is an image for informing the driver that the driving support control 40 is operating, is displayed on the liquid crystal display device 26. Perform display control. Further, during the operation of the driving support control, the display controller 30 continuously displays the support state display image corresponding to the operating driving support control on the liquid crystal display device 26, and the driving operation in progress. When it is determined that the support control has ended before the preset minimum display time tmin has elapsed, the minimum display time tmin has elapsed in displaying the support state display image corresponding to the driving support control in operation on the liquid crystal display device 26. Display control that continues until

Here, the operation time of the driving support control varies, and the operation may be performed for a relatively short time depending on the operation state. In contrast to such driving assistance control that operates only for a relatively short time, when the assistance state display image is displayed for a short time, the assistance state display image is displayed instantaneously. Such a display is a cumbersome display for the driver who cannot recognize what is displayed.
That is, for example, the minimum display time tmin is set to an appropriate time for the driver to recognize the display contents, and the display of the support state display image is continued at least until the minimum display time tmin elapses. Do. Thus, the driver can recognize what kind of driving support control has been activated without feeling bothered.

(9) The minimum display time tmin is set for each type of driving support control.
By setting the minimum display time tmin for each type of driving support control, for example, for driving support control with a relatively large driving load, flexibility such as increasing the display time of the support state display image to improve visibility Display mode.
(10) The display control controller 30 detects the operating state of the driving support control performed by the in-vehicle driving support device 40. When the display controller 30 determines that the driving support control is activated, the display control controller 30 performs display control for displaying on the display device an assistance state display image that is an image for notifying the driver of the operation. When the display controller 30 determines that the driving load when the driving support control is determined to be relatively large, the display controller 30 is viewed from the viewpoint of looking down the vehicle from the upper rear side on the mesh image that is a mesh-like planar image. Display control for displaying a high load support state display image having a configuration in which one vehicle image (vehicle image 261b or the like) is overlaid and displaying the display mode of the mesh image portion in a preset display mode is performed. When the display controller 30 determines that the driving load at the time when it is determined that the driving support control is activated, the second vehicle image (vehicle image 261f) viewed from the viewpoint of viewing the side of the vehicle from the front. Or 261h), and display control for displaying a display mode of the wheel portion of the second vehicle image in a preset display mode, while displaying a low load support state display image (effect image 261HSA or 261HDC). .

  For example, when the vehicle speed of the vehicle V is relatively high, the vehicle V is making a turning motion, or the vehicle V is moving over a large-sized unevenness, the driving load is relatively large. . In such a situation, it is difficult for the driver to gaze at the display screen of the liquid crystal display device 26 or to recognize detailed display contents. On the other hand, for example, when the vehicle V is stopped or starting from a stopped state on a steep uphill, or when the vehicle V is traveling on a steep downhill or snowy road at a relatively low vehicle speed, Is a relatively small situation. In such a situation, it is relatively easy for the driver to recognize the display contents by looking at the display screen 260 of the liquid crystal display device 26.

  Therefore, when the driving load when the driving support control is activated is relatively large, the first vehicle image including the first vehicle image viewed from the viewpoint of looking down at the vehicle from the upper rear side is included, and the first vehicle image is mesh-shaped. A high load support state display image with a composition arranged on the plane image is displayed. In addition, the display mode of the mesh image portion is displayed in a preset display mode such that the mesh image portion around the first vehicle image is displayed by light emission. Accordingly, the driver can recognize that the driving assistance control is operating by instantaneous line-of-sight movement or peripheral visual field without gazing at the display screen 260 of the liquid crystal display device 26.

  On the other hand, when the driving load when the driving support control is activated is relatively small, the low load support state display image including the second vehicle image of the viewpoint when the vehicle is viewed from the front side is displayed. The display mode of the wheel image portion is displayed in a preset display mode such that the tire portion of the wheel image in the second vehicle image is light-emitting displayed or blinked. As a result, the driver can recognize the relatively fine operation status of the driving support control from the display content of the display screen 260 of the liquid crystal display device 26.

(11) When the first condition set in advance is satisfied (for example, when the driver is stepping on the brake pedal 16 and the vehicle V is stopped), the driving support control operates in a standby state. When the preset second condition is satisfied (when the driver removes his / her foot from the brake pedal 16), a time difference type driving support control for shifting to the control execution state is included. When the display controller 30 determines that the driving load is relatively small when it is determined that the time-difference driving support control (for example, the driving support control HSA) is activated in the standby state, a low load support state display image is displayed. At the same time, the wheel portion of the second vehicle image in the low load support state display image is displayed in a display color that produces a display effect that appears to be emitted (for example, the effect image 261HSA (S) is displayed on the wheel. ) Perform display control. When the display controller 30 determines that the driving load is relatively small when it is determined that the time difference type driving support control has shifted from the standby state to the operating state, the second vehicle image in the low load support state display image. The display of the wheel portion in a display color that produces a display effect that appears to emit light and a display color that produces a display effect that appears to turn off are alternately repeated (for example, the effect image 261HSA (O) is displayed). Wheel display blinking) Display control.

  As a result, for example, as in the driving support control HSA that operates in a situation where the driving load is relatively small, when the vehicle V is stopped by stepping on the brake pedal 16, the vehicle enters a standby state (operation preparation state), and thereafter the foot from the brake pedal 16 It is possible to display highly recognizable information with respect to the driving support control that is activated by releasing the button.

(12) A low load support state display image (effect image 261HSA or 261HDC) corresponding to driving support control (driving support control HSA, HDC, etc.) operating on a hill is displayed on a hill display line (inclination line indicating a hill). The second vehicle image (vehicle image 261f or 261h) is disposed so as to include the uphill display line 266 or the downhill display line 267), and the slope display line is used as a ground contact surface of the tire portion of the second vehicle image. The configuration.
As a result, the driver can easily recognize that the driving support control operating on the slope is operating by looking at the display screen 260 of the liquid crystal display device 26.

(Second Embodiment)
Next, 2nd Embodiment of this invention is described based on drawing. 18-20 is a figure which shows embodiment of the display control apparatus for vehicles and the display control method for vehicles which concerns on 2nd Embodiment of this invention.
(Constitution)
In the first embodiment, when another driving assistance control is activated later while a certain driving assistance control is in operation, the first assistance state display image that is currently displayed is the driving assistance control that has been activated later. The second support state display image corresponding to is immediately switched and displayed. On the other hand, in this embodiment, when it is determined that the display time of the first support state display image that has been displayed first has not passed the preset switching display time, the switching display time elapses. Display of the first support state display image is continued. Thereafter, the second support state display image is displayed, which is different from the first embodiment.
In addition, the same code | symbol is attached | subjected to the structure similar to the said 1st Embodiment, and the overlapping description is abbreviate | omitted.

FIG. 18 is a block diagram showing a configuration of the display control controller 30 of the present embodiment.
As shown in FIG. 18, the display controller 30 according to the present embodiment includes a display control ECU 300, an effect information storage memory 302, a display time measurement timer 304, and an operation order storage memory 306.
The operation order storage memory 306 is a memory for storing the operation order of the driving support control.
The display control ECU 300 includes an input processing unit 300A and a display control unit 300B. In the present embodiment, the display control unit 300B includes a display time delay processing unit 300C, an output signal processing unit 300D, and an order determination unit 300E.

When the display time delay processing unit 300C of the present embodiment determines that the driving support control is operating based on the input operation flag, the driving support control determined to be operating from the effect information storage memory 302. The minimum display time information corresponding to is read. Then, the display time delay processing unit 300C inputs the minimum display time information to the output signal processing unit 300D, and inputs the input operation flag to the order determination unit 300E.
The order determination unit 300E stores the operation order of the driving support control in the operation order storage memory 306 based on the operation flag input from the display time delay processing unit 300C. And based on the memorize | stored operation | movement order, the display order of the image for assistance state display corresponding to each driving assistance control is determined.
In the present embodiment, the order determining unit 300E inputs information indicating this to the output signal processing unit 300D when only one driving support control is operating or when none is operating.

In addition, when two or more types of driving support controls are continuously overlapped and operated, the order determination unit 300E uses the operation order stored in the operation order storage memory 306 as a display order, and outputs information on the display order as an output signal. Input to the processing unit 300D.
Furthermore, the order determination unit 300E determines the display order according to the operation conditions of the driving support control when two or more types of driving support control are simultaneously operated. The order determination unit 300E inputs information on the determined display order to the output signal processing unit 300D.
Here, the operation condition of the driving support control is, for example, a condition that is satisfied according to the driver operating the driving operator such as the steering wheel 1 or a condition that is satisfied according to the input of the disturbance. There is. In the present embodiment, the driving support control in which the operating condition is established according to the operation of the driving operator corresponds to, for example, driving support control ATC and AEB that operate according to the operation of the steering wheel 1. On the other hand, in the present embodiment, the driving support control in which the operation condition is established according to the input of the disturbance corresponds to, for example, the driving support control ARC that operates according to overcoming (input) of the road surface unevenness (disturbance). .

  In the present embodiment, operation-responsive driving support control, which is driving support control in which control intervenes according to the operation of the driver's driving operator, and disturbance-responsive driving, which is driving support control in which control intervenes in response to disturbance input. When the assist control is activated simultaneously, priority is given to the operation support driving support control. That is, the order determination unit 300E determines the display order of the support state display images corresponding to the operation support driving support control in an order before the display order of the support state display images corresponding to the disturbance support driving support control. .

  Next, the output signal processing unit 300D of the present embodiment displays based on the switching display time tsw that is set in advance for each type of driving support control when two or more types of driving support control operate in succession. Take control. In the present embodiment, the switching display time tsw is set to a time shorter than the minimum display time tmin described in the first embodiment. For example, when the minimum display time tmin is set to 2.5 [s], the switching display time tsw is set to 2.0 [s], for example. That is, the minimum display time tmin is a time for improving the recognizability of the display contents of the driver, whereas the switching display time tsw is annoying to the driver by a short display switching. It is time to resolve. Specifically, in the first embodiment, the support state display image corresponding to the driving support control that has started operation later is immediately switched to the previously displayed support state display image. At this time, when the display time of the previously displayed support state display image is extremely short, after the previous support state display image is displayed for a moment, the subsequent support state display image is displayed. For this reason, the driver cannot recognize what is displayed and feels bothered.

  In the present embodiment, the output signal processing unit 300D uses the display time measurement timer 304 to display a support state display image (hereinafter referred to as first drive support control) corresponding to the drive support control (hereinafter referred to as first drive support control) that has started to operate. The display time of the first support state display image) is measured. Based on the measured display time, the output signal processing unit 300D determines that the display time of the first support state display image is a switching display time tsw (hereinafter referred to as the first display time) set in advance for the first driving support control. It is determined whether or not the switching display time tsw1 has elapsed. If it is determined by this determination that the output signal processing unit 300D has not elapsed, display control for continuously displaying the first support state display image is performed until the first switching display time tsw1 has elapsed.

  Subsequently, the output signal processing unit 300D displays an assistance state display image (hereinafter, referred to as a second assistance state display image) corresponding to the driving assistance control (hereinafter, referred to as second driving assistance control) that has started to operate later. Is displayed on the liquid crystal display device 26. Also at this time, the output signal processing unit 300D measures the display time by the display time measuring timer 304. Then, the output signal processing unit 300D of the present embodiment displays the second support state display image based on the measurement time, at least a switching display time tsw (hereinafter, referred to as “second display”) for the second driving support control. Display control is performed until the second switching display time (tsw2) elapses.

Hereinafter, display control of the second support state display image will be described.
First, the case where the operation time of the second driving support control is equal to or shorter than the minimum display time tmin will be described. In this case, the minimum display time after the display of the second support state display image is started with respect to the time from when the second driving support control is activated until the minimum display time tmin elapses. It is assumed that the time until tmin elapses (hereinafter referred to as second display time tsh2) is shorter than the second switching display time tsw2. In this case, the output signal processing unit 300D performs display control for continuously displaying the second support state display image until the second switching display time tsw2 elapses.

On the other hand, when the second display time tsh2 is equal to or longer than the second switching display time tsw2, in the present embodiment, the output signal processing unit 300D displays the second support state display image as the second display time tsh2. Display control to display until it passes.
Next, a case where the operation time of the second driving support control is longer than the minimum display time tmin and the display time of the second support state display image is longer than the second switching display time tsw2 will be described. Also in the present embodiment, as in the first embodiment, during the operation of the driving support control, display control is performed to continue displaying the support state display image corresponding to the operating driving support control. Accordingly, the output signal processing unit 300D performs display control for continuously displaying the second support state display image until the second driving support control is completed.
Note that the second support state display image is not limited to the configuration for displaying at least the second switching display time tsw2, but at least the second support state display image is displayed, and then the second driving support control is performed. On the other hand, it may be configured to display until a preset minimum display time elapses.

Further, the switching display time tsw is set similarly for the default image. For example, it is assumed that another driving support control is activated before a switching display time tsw set in advance for the default image has elapsed after returning to the display of the default image after a certain driving support control is completed. In this case, the output signal processing unit 300D continues to display the default image until a preset switching display time tsw has elapsed for the default image.
In the present embodiment, the information about the switching display time is included in the display pattern information stored in the effect information storage memory 302.

On the other hand, the output signal processing unit 300D performs display control based on the display order input from the order determining unit when the operation corresponding driving support control and the disturbance corresponding driving support control operate simultaneously.
In the present embodiment, since the display order is determined so that the operation support driving support control comes first, the output signal processing unit 300D displays the support state display image corresponding to the operation support driving support control (hereinafter referred to as operation). Display control of the corresponding display image) is performed first. Specifically, the output signal processing unit 300D first performs display control to display the operation-related display image until the minimum display time preset for the operation-related driving support control elapses. Thereafter, display control of a support state display image (hereinafter referred to as a disturbance response display image) corresponding to the disturbance response driving support control is performed. Specifically, in the present embodiment, display control for displaying a disturbance-corresponding display image until a minimum display time set in advance for disturbance-responsive driving support control elapses is performed.

(Operation)
Hereinafter, based on FIGS. 19-20, the operation example of this embodiment is demonstrated.
[Display control operation during continuous operation]
Based on FIG. 19, the display control operation in the case where the driving support control is operated in a continuous manner will be described. FIG. 19 is a time chart for explaining an example of the display control operation in the case where the driving support control is continuously overlapped and operated.
First, as shown in (1) in FIG. 19, when the operation flag A of the driving support control A is turned ON, the display time delay processing unit 300C receives driving assistance as minimum display time information from the effect information storage memory 302. Read the minimum display time tminA corresponding to the control A. In the present embodiment, the driving assistance control A is any one of driving assistance control ATC, AEB, ARC, SMB, and HDC.

The display time delay processing unit 300C inputs the read minimum display time tminA to the output signal processing unit 300D. Further, the display time delay processing unit 300C inputs the input operation flag to the order determination unit 300E.
The order determination unit 300E stores the operation order of the driving support control in the operation order storage memory 306 based on the input operation flag. As shown in (1) in FIG. 19, since the driving support control A is first operating, the order determination unit 300E stores information on the operating order (No. 1) of the driving support control A in the operation order storage memory 306. Remember. Then, display order information indicating that the driving support control A is operating is input to the output signal processing unit 300D.

  When the output signal processing unit 300D determines that the driving support control A is in an operating state based on the display order information input from the order determining unit 300E, the display pattern corresponding to the driving support control A from the effect information storage memory 302 is displayed. Read information A. Then, based on the read display pattern information A, a display start command A for an assistance state display image X (hereinafter referred to as an effect image A) corresponding to the driving assistance control A is generated. Furthermore, the output signal processing unit 300 </ b> D transmits the generated display start command A to the meter device 20 via the communication network 50. On the other hand, the output signal processing unit 300D outputs a count operation start command to the display time measurement timer 304, and starts the count operation (display time measurement) by the display time measurement timer 304.

  On the other hand, when receiving the display start command A from the output signal processing unit 300D, the meter controller 28 of the meter device 20 reads information on the effect image A corresponding to the received display start command A from the effect image storage memory 29. . Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal A of an image to be displayed on the display screen 260 is generated based on the read information of the effect image A and the acquired various information, and the generated image display signal A is input to the liquid crystal display device 26.

Based on the input image display signal A, the liquid crystal display device 26 displays the effect image A on the display screen 260 as shown in (2) of FIG.
Subsequently, as shown in (3) in FIG. 19, when the operation flag B of the driving support control B is turned on while the driving support control A is operating, the display time delay processing unit 300C reads from the effect information storage memory 302. The minimum display time tminB corresponding to the driving support control B is read out as the minimum display time information. Then, the read minimum display time tminB is input to the output signal processing unit 300D. Further, the display time delay processing unit 300C inputs the input operation flag to the order determination unit 300E.

The order determination unit 300E stores information on the operation order (No. 2) of the driving support control B in the operation order storage memory 306 based on the input operation flag. Then, display order information indicating that the driving support control A is No. 1 and the driving support control B is No. 2 based on the stored operation order information is input to the output signal processing unit 300D.
When the output signal processing unit 300D determines that the driving support control B is in an operating state during the operation of the driving support control A based on the display order information input from the order determining unit 300E, the output signal processing unit 300D drives from the effect information storage memory 302. Display pattern information B corresponding to support control B is read.

  On the other hand, based on the count value of the display time measurement timer 304, the output signal processing unit 300D determines whether or not the display time of the effect image A has passed the switching display time tswA that is preset for the driving support control A. Determine. As shown in (2) to (3) in FIG. 19, when the driving support control B is activated, the display time of the effect image A (tshA in FIG. 19) is shorter than the switching display time tswA. Therefore, the output signal processing unit 300D performs display control so that the effect image A is continuously displayed until the display time of the effect image B has passed the switching display time tswA. That is, if the output signal processing unit 300D determines that the display time of the effect image A has passed the switching display time tswA, the output state processing image 300D (hereinafter referred to as the support state display image B corresponding to the driving support control B based on the display pattern information B). A display switching command B of the effect image B) is generated. Then, the generated display switching command B is transmitted to the meter device 20 via the communication network 50. On the other hand, the output signal processing unit 300D outputs a reset command to the display time measurement timer 304 to reset the count value, and subsequently outputs a count operation start command to perform the count operation by the display time measurement timer 304. Start.

  When the meter controller 28 of the meter device 20 receives the display switching command B from the output signal processing unit 300D, the meter controller 28 reads information on the effect image B corresponding to the received display switching command B from the effect image storage memory 29. Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal B of an image to be displayed on the display screen 260 is generated based on the read information of the effect image B and the acquired various information, and the generated image display signal B is input to the liquid crystal display device 26.

Based on the input image display signal B, the liquid crystal display device 26 displays the effect image B instead of the effect image A on the display screen 260 as shown in (4) of FIG.
In the example of (1) to (4) in FIG. 19, the time when the minimum display time tminA has elapsed from the operation start time t1 of the driving support control B is time t3. The time from the display start time t2 to the time t3 of the effect image B, that is, the display time tshB of the effect image B is equal to or longer than the switching display time tswB preset for the driving support control B.
Therefore, the output signal processing unit 300D performs display control for displaying the effect image B until the display time tshB elapses. That is, when the output signal processing unit 300D determines that the display time of the effect image B has passed the display time tshB, the output signal processing unit 300D generates a display end command for the effect image B. Then, the generated display end instruction is transmitted to the meter device 20 via the communication network 50.

When the meter controller 28 of the meter device 20 receives the display end command from the output signal processing unit 300D, the meter controller 28 reads information on the default image 261DF from the effect image storage memory 29. Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal DF of an image to be displayed on the display screen 260 is generated based on the read information of the default image 261DF and the acquired various information, and the generated image display signal DF is input to the liquid crystal display device 26.
The liquid crystal display device 26 displays a default image 261DF on the display screen 260 instead of the effect image B based on the input image display signal DF.

Next, operation examples shown in (5) to (8) in FIG. 19 will be described. The difference from (1) to (4) in FIG. 19 is that the start time of the driving support control B is early. Therefore, the time (display time tshB) from the display start time t5 to the time t6 of the effect image B is the switching display time tswB with respect to the time t6 when the minimum display time tminB has elapsed from the operation time t4 of the driving support control B. Is shorter.
In such a case, the output signal processing unit 300D performs display control for continuously displaying the effect image B from the display start time t5 until the switching display time tswB elapses, that is, from the time t5 to the time t7.

[Display control operation during multiple operations]
Next, based on FIG. 20, a display control operation in the case where the operation corresponding driving support control and the disturbance corresponding driving support control are simultaneously operated will be described. FIG. 20 is a time chart for explaining an example of the display control operation when the operation-responsive driving support control and the disturbance-responsive driving support control are simultaneously activated.
Hereinafter, the operation flag of the operation support driving support control is referred to as an operation support operation flag, and the operation flag of the disturbance support driving support control is referred to as a disturbance response operation flag.

  As shown in (1) to (2) in FIG. 20, it is assumed that the operation corresponding operation flag C and the disturbance corresponding operation flag D are simultaneously turned ON. In this case, the display time delay processing unit 300C reads from the effect information storage memory 302 the minimum display time tminC corresponding to the operation support driving support control C as the minimum display time information. Furthermore, the display time delay processing unit 300C reads the minimum display time tminD corresponding to the disturbance handling driving support control D from the effect information storage memory 302 as the minimum display time information. In the present embodiment, the operation corresponding driving support control C is one of the driving support control ATC and AEB. In the present embodiment, the disturbance handling driving support control D is the driving support control ARC.

The display time delay processing unit 300C inputs the read minimum display times tminC and tminD to the output signal processing unit 300D. Further, the display time delay processing unit 300C inputs the input operation flag to the order determination unit 300E.
The order determination unit 300E stores the operation order of the driving support control in the operation order storage memory 306 based on the input operation flag. In this case, the order determination unit 300E stores operation order information indicating that the operation corresponding driving support control C and the disturbance corresponding driving support control D are simultaneously operated in the operation order storage memory 306. Furthermore, the order determination unit 300E generates display order information in which the operation-corresponding driving support control C is No. 1 and the disturbance-corresponding driving support control D is No. 2, based on the stored operation order information, and the generated display order information Is input to the output signal processing unit 300D.

  The output signal processing unit 300D reads the display pattern information C corresponding to the operation support driving support control C from the effect information storage memory 302 based on the display order information input from the order determining unit 300E. Then, based on the read display pattern information C, a display start command C for a support state display image C (hereinafter referred to as an effect image C) corresponding to the operation support driving support control C is generated. Further, the output signal processing unit 300 </ b> D transmits the generated display start command C to the meter device 20 via the communication network 50. On the other hand, the output signal processing unit 300D outputs a count operation start command to the display time measurement timer 304 and starts the count operation by the display time measurement timer 304.

  On the other hand, when receiving the display start command C from the output signal processing unit 300D, the meter controller 28 of the meter device 20 reads information on the effect image C corresponding to the received display start command C from the effect image storage memory 29. . Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal C of an image to be displayed on the display screen 260 is generated based on the read information of the effect image C and the acquired various information, and the generated image display signal C is input to the liquid crystal display device 26.

Based on the input image display signal C, the liquid crystal display device 26 displays the effect image C on the display screen 260 as shown in (3) in FIG.
In the example of FIG. 20, since the operation time toC of the operation corresponding driving support control C is shorter than the minimum display time tminC, the output signal processing unit 300D has the minimum display time tminC after the operation corresponding driving support control C ends. Display control is performed to continuously display the effect image C until the time has elapsed.

  Specifically, when the output signal processing unit 300D determines that the display time of the effect image C has passed the minimum display time tminC, the output signal processing unit 300D reads the display pattern information D corresponding to the disturbance corresponding driving support control D from the effect information storage memory 302. . Then, based on the read display pattern information D, a display switching command D for an assistance state display image D (hereinafter referred to as an effect image D) corresponding to the disturbance handling driving assistance control D is generated. Then, the generated display switching command D is transmitted to the meter device 20 via the communication network 50. On the other hand, the output signal processing unit 300D outputs a reset command to the display time measurement timer 304 to reset the count value, and subsequently outputs a count operation start command to perform the count operation by the display time measurement timer 304. Start.

  When the meter controller 28 of the meter device 20 receives the display switching command D from the output signal processing unit 300D, the meter controller 28 reads information on the effect image D corresponding to the received display switching command D from the effect image storage memory 29. Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal D of an image to be displayed on the display screen 260 is generated based on the read information of the effect image D and the acquired various information, and the generated image display signal D is input to the liquid crystal display device 26.

The liquid crystal display device 26 displays the effect image D instead of the effect image C on the display screen 260 based on the input image display signal D, as shown in (4) of FIG.
In the example of FIG. 20, since the operation time toD of the disturbance handling operation support control D is shorter than the minimum display time tminD, the output signal processing unit 300D has the minimum display time tminD even after the disturbance handling operation support control D ends. Display control for continuously displaying the effect image D until the time has elapsed.

Specifically, when the output signal processing unit 300D determines that the display time of the effect image D has passed the minimum display time tminD, the output signal processing unit 300D generates a display end command for the effect image D. Then, the generated display end instruction is transmitted to the meter device 20 via the communication network 50.
When the meter controller 28 of the meter device 20 receives the display end command from the output signal processing unit 300D, the meter controller 28 reads information on the default image 261DF from the effect image storage memory 29. Furthermore, the meter controller 28 acquires various information to be displayed in the first display area 260A, the second display area 260B, and the fourth display area 260D from another controller, instrument, or the like via the communication network 50. Then, an image display signal DF of an image to be displayed on the display screen 260 is generated based on the read information of the default image 261DF and the acquired various information, and the generated image display signal DF is input to the liquid crystal display device 26.
The liquid crystal display device 26 displays a default image 261DF on the display screen 260 instead of the effect image D based on the input image display signal DF.
Here, in the present embodiment, the function for determining the operation state of the driving support control based on the operation flag of the display controller 30 corresponds to the operation state determination unit. The display control function of the support state display image of the display controller 30 corresponds to the display control unit.

(Effect of 2nd Embodiment)
According to this embodiment, in addition to the effects of the first embodiment, the following effects can be achieved.
(1) When the display controller 30 determines that the driving support control performed by the in-vehicle driving support device 40 is in operation, the display controller 30 is for displaying an assistance state that is an image for informing the driver that the driving is being operated. The image is displayed on a liquid crystal display device 26 provided in the meter panel 21 of the meter device 20. The display control controller 30 determines that the second driving support control different from the first driving support control has been operated while the first driving support control is being operated, and the first driving display previously displayed When it is determined that the display time of the first support state display image corresponding to the driving support control has not passed the preset switching display time tsw, the switching display time tsw has passed through the first support state display image. Display control is performed until the display control is performed, and display control for displaying a second support state display image corresponding to the second driving support control is performed after the display control is executed.

That is, if it is determined that the second driving support control has been operated while the first driving support control is in operation, the display time of the first support state display image that has been displayed has passed the switching display time tsw. It is determined whether or not. If it is determined that the switching display time tsw has not elapsed, the display control for immediately switching to and displaying the second support state display image is not performed, and the first display until the switching display time tsw has elapsed. 1 support state display image is continuously displayed.
Thereby, even when the second driving support control is activated at the timing when the first support state display image is displayed for a very short time, the first support state display image is always displayed until the switching display time tsw elapses. Is displayed. Therefore, by setting the switching display time tsw to an appropriate time, it is possible to prevent an extremely short display state of the support state display image from being generated, and the troublesomeness given to the driver by such display is reduced. It becomes possible to do.

(2) Operation support driving support control (for example, driving support control ATC, AEB, etc.) that the display controller 30 operates according to the operation of the driver's driving operator (steering wheel 1, brake pedal 16, accelerator pedal, etc.) ) And disturbance-responsive driving support control (for example, driving support control ARC, etc.) that operates in response to a disturbance are activated at the same time. Status display images (effect images 261IN, 261LC, 261RC, etc.) are displayed. Then, after the display, display control for displaying a support state display image (such as the effect image 261ARC) corresponding to the disturbance responsive driving support control is performed.

  The operation-supporting driving support control operates in accordance with the operation of the driving operation element such as the steering wheel 1 by the driver, and thus operates under a driving condition recognized by the driver. On the other hand, the disturbance-responsive driving support control operates in response to an input of disturbance such as road irregularities, and thus may operate in a situation that is not recognized by the driver. Therefore, when the operation support driving support control and the disturbance support driving support control are activated at the same time, the support state display image corresponding to the operation support driving support control is preferentially displayed, so that appropriate support is provided at an appropriate timing. It is possible to display a state display image.

(3) The switching display time tsw is set for each type of driving support control.
By setting the switching display time tsw for each type of driving support control, it is possible to set the time according to the display content, and by setting an appropriate time for each display content, switching with less troublesomeness Display can be performed.

(Modification)
(1) In the above embodiment, the driving support controls HSA and HDC are set in advance as controls that operate in a relatively small driving load, and the driving support controls ATC, AEB, ARC, and SMB are set in a relatively large driving load. It was preset as a control to operate. The driving support control that operates when the driving load is relatively large and the driving support control that operates when the driving load is relatively small include vehicle images viewed from different viewpoints and display modes during control operation. A different support state display image is displayed.
For example, when the display controller 30 determines that the vehicle speed Vd is equal to or higher than a preset vehicle speed threshold based on the vehicle speed Vd of the vehicle V, the driving load is determined to be relatively large. If it is determined that it is less than the vehicle speed threshold, it is determined that the driving load is relatively small. Then, based on the determination result, the driving support control that operates in a situation where the driving load is relatively large and the driving support control that operates in a situation where the driving load is relatively small include and control a vehicle image viewed from different viewpoints. It is good also as a structure which displays the image for assistance state display from which the display mode at the time of an operation | movement differs.

For example, in a situation where the vehicle speed Vd is equal to or higher than the vehicle speed threshold, a display that allows the driver to recognize a rough operating state such as what kind of driving support control is operating with quick line-of-sight movement and peripheral vision It is possible to display a support state display image of the content. On the other hand, in a situation where the vehicle speed Vd is less than the vehicle speed threshold, the driver can view the display content, for example, to display a support state display image with a display content that understands the detailed operation status of the drive support control. It becomes possible.
This can be applied not only to different driving support controls but also to the same driving support control. That is, it is possible to change the displayed content to an appropriate content according to the magnitude of the driving load when the driving load is relatively large and when the driving load is relatively small even with the same driving support control.

(2) In the above embodiment, the driving support controls HSA and HDC are set in advance as controls that operate in a relatively small driving load, and the driving support controls ATC, AEB, ARC, and SMB are set in a relatively large driving load. It was preset as a control to operate. The driving support control that operates when the driving load is relatively large and the driving support control that operates when the driving load is relatively small include vehicle images viewed from different viewpoints and display modes during control operation. A different support state display image is displayed.

  For example, the display controller 30 detects the gradient of the travel path based on the detection value of an inclination angle sensor (not shown) mounted on the automobile V. And if it determines with the detected gradient being more than the preset gradient threshold value, it will determine with driving load being comparatively large, and if it determines with the detected gradient being less than gradient threshold value, it will determine with driving load being comparatively small. . Then, based on the determination result, the driving support control that operates in a situation where the driving load is relatively large and the driving support control that operates in a situation where the driving load is relatively small include and control a vehicle image viewed from different viewpoints. It is good also as a structure which displays the image for assistance state display from which the display mode at the time of an operation | movement differs.

For example, in a situation where the gradient of the road is greater than or equal to the gradient threshold, the driver can recognize a rough operating condition such as what kind of driving support control is operating with quick line-of-sight movement and peripheral vision It is possible to display an image for displaying the support state of the display content. On the other hand, in a situation where the gradient of the travel path is less than the gradient threshold, the driver views the display content, for example, displays a support state display image of the display content that understands the detailed operation status of the driving support control. It becomes possible.
This can be applied not only to different driving support controls but also to the same driving support control. That is, it is possible to change the displayed content to an appropriate content according to the magnitude of the driving load when the driving load is relatively large and when the driving load is relatively small even with the same driving support control.
