[0003] [Patent Document 1] JP 2017-087980 A Summary of the Invention [Problem to be solved by the invention]

[0004] The invention of Patent Document 1 above has room for improvement in terms of displaying information on a display provided on an instrument panel and a head-up display so as to reduce the annoyance felt by occupants and the risk of the occupants being unable to recognize the displayed information.

[0005] In consideration of the above-mentioned facts, the present invention aims to provide a vehicle display control device, a vehicle display device, a vehicle, a vehicle display control method, and a program that are capable of displaying a specified message on a first display unit and a second display unit provided in a vehicle, while minimizing the risk of the occupant feeling annoyed and the risk of the occupant being unable to recognize the displayed information. [Means for solving the problem]

[0006] The vehicle display control device described in claim 1 includes a processor, and when an occupant of the vehicle performs a first operation while a predetermined message is displayed on a first display unit provided in the vehicle and a second display unit that is different from the first display unit, the processor controls the first display unit and the second display unit so that the message is erased from the first display unit and the message remains displayed on the second display unit.

[0007] In the vehicle display control device described in claim 1, when a vehicle occupant performs a first operation while a predetermined message is displayed on a first display unit and a second display unit provided in the vehicle, the message is erased from the first display unit. In this way, in the vehicle display control device described in claim 1, since the occupant can erase the message from the first display unit at their own will, the occupant is less likely to feel annoyed compared to a case in which the messages displayed on the first display unit and the second display unit cannot be erased at the occupant's will.

[0008] Furthermore, in the vehicle display control device described in claim 1, when a vehicle occupant performs a first operation while a predetermined message is displayed on the first display unit and the second display unit provided in the vehicle, the message remains displayed on the second display unit. Therefore, even if the message is erased from the first display unit, the occupant can still recognize the message displayed on the second display unit.

[0009] The vehicle display control device of the invention described in claim 2 is the invention described in claim 1, in which a predetermined operation on a steering switch provided on a steering wheel of the vehicle is the first operation, and the processor controls the first display unit to display a steering switch image representing the steering switch when the occupant performs the first operation while the message is displayed on the first display unit and the second display unit.

[0010] In the invention described in claim 2, when the occupant performs a first operation on the steering switch, a steering switch image representing the steering switch is displayed on the first display unit. Therefore, the occupant can recognize the positional relationship between the part of his / her body (e.g., a hand) that performed the first operation and the steering switch by looking at the first display unit.

[0011] The invention of claim 3 provides a vehicle display control device according to the invention of claim 2, wherein the first display unit is capable of displaying a plurality of types of messages having a display priority order, and when the occupant performs the first operation while a first message, which is the message whose priority order is equal to or lower than the priority order of the steering switch image, is displayed on the first display unit, the first message is erased and the steering switch image is displayed, and when the occupant performs the first operation while a second message, which is the message whose priority order is higher than the priority order of the steering switch image, is displayed on the first display unit, The second message and controls the first display unit so as to keep the steering switch image displayed and not to display the steering switch image.

[0012] In the invention described in claim 3, when the occupant performs the first operation in a state in which the first message, which is a message having a priority level lower than that of the steering switch image, is displayed on the first display unit, the first message is erased from the first display unit and the steering switch image is displayed on the first display unit. Therefore, in this case, the occupant can recognize the steering switch image having a priority level higher than that of the first message by looking at the first display unit.

[0013] In the vehicle display control device according to claim 3, when a passenger performs a first operation in a state where a second message, which is a message having a higher priority than the priority of a steering switch image, is displayed on the first display unit, Second Messageremains displayed on the first display unit, and the steering switch image is not displayed on the first display unit. Therefore, in this case, the occupant can see the second message, which has a higher priority than the steering switch image, by looking at the first display unit.

[0014] The invention recited in claim 4 provides the vehicle display control device recited in claim 2 or 3, wherein the first operation is an operation in which a part of the body of the occupant comes into contact with the steering switch.

[0015] In the invention described in claim 4, when a part of the occupant's body touches the steering switch, the message is erased from the first display section, so that the occupant can easily erase the message from the first display section.

[0016] The vehicle display control device according to the invention described in claim 5 is an invention described in any one of claims 1 to 4, wherein the processor controls the second display unit so that the message is erased from the second display unit when the occupant performs a second operation different from the first operation while the message is displayed on the second display unit.

[0017] In the invention described in claim 5, the message is erased from the second display unit when the occupant performs a second operation different from the first operation. Therefore, the possibility that the occupant will erroneously erase the message from the first display unit and the second display unit is low compared to a case in which the message is erased from the first display unit and the second display unit when the first operation is performed.

[0018] The vehicle display control device of the invention described in claim 6 is the invention described in claim 5, wherein the second display unit is capable of displaying multiple types of messages having a display priority order, and when the occupant performs the second operation while a third message, which is a message whose priority order is lower than a predetermined standard priority order, is displayed on the second display unit, the third message is erased from the second display unit, and when the occupant performs the second operation while a fourth message, which is a message whose priority order is higher than the standard priority order, is displayed on the second display unit, the second display unit is controlled to leave the fourth message displayed.

[0019] In the invention described in claim 6, when the occupant performs the second operation while the second display unit displays the third message, which is a message whose priority is equal to or lower than a predetermined reference priority, the third message is erased from the second display unit. Therefore, in this case, the occupant does not feel annoyed by the third message displayed on the second display unit.

[0020] In the vehicle display control device according to claim 6, when the occupant performs the second operation while the second display unit displays the fourth message, the fourth message being a message with a higher priority than the reference priority, the second display unit continues to display the fourth message. Therefore, even if the occupant mistakenly performs the second operation, the occupant can recognize the fourth message, which has a higher priority, by looking at the second display unit.

[0021] The vehicle display control device of the invention described in claim 7 is the invention described in claim 5 or claim 6, in which a set display time of the message on the first display unit when the first operation is not performed, and a set display time of the message on the second display unit when the second operation is not performed are set for each of the messages.

[0022] In the invention described in claim 7, a set display time of the message on the first display unit when the first operation is not performed, and a set display time of the message on the second display unit when the second operation is not performed are set for each message. Therefore, it is possible to make it difficult for the passenger to feel annoyed by the messages displayed on the first display unit and the second display unit.

[0023] The vehicle display control device of the invention described in claim 8 is an invention described in any one of claims 5 to 7, in which the second operation is an operation of moving a steering switch provided on a steering wheel of the vehicle and movable between an initial position and a depressed position, to the depressed position.

[0024] In the invention described in claim 8, when an occupant performs an operation to move a steering switch that is movable between an initial position and a depressed position to the depressed position, the message is erased from the second display unit. Therefore, the possibility that an occupant will erroneously erase the message from the second display unit is reduced compared to when a message is erased from the second display unit when a part of the body touches the steering switch.

[0025] The invention recited in claim 9 provides the vehicle display control device recited in any one of claims 1 to 8, wherein the first display unit is a head-up display.

[0026] In the invention recited in claim 9, when the occupant performs the first operation, the message displayed on the head-up display can be erased.

[0035] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a vehicle display control device, a vehicle display device, a vehicle, a vehicle display control method, and a program according to the present invention will be described with reference to the drawings.

[0036] 1, a vehicle 10 of this embodiment includes a front windshield 14 and an instrument panel 16. The instrument panel 16 is provided with a meter display (display) (first display unit) (second display unit) (vehicle display device) 18. A sensor group 20 is provided on an upper portion of the interior surface of the front windshield 14. The sensor group 20 includes at least one of a camera, a Lidar (Laser Imaging Detection and Ranging) sensor, a locator camera, and a millimeter wave radar sensor.

[0037] The meter display (MET) 18 provided on the instrument panel 16 is controlled by a display control ECU (vehicle display control device) (vehicle display device) 26, which will be described later. The display control ECU 26 is connected to various meter devices mounted on the vehicle 10. Therefore, for example, information related to the vehicle speed of the vehicle 10 is displayed on the meter display 18, as shown in FIG.

[0038] A display area (first display section) (second display section) HA is formed on the front windshield 14. The display area HA is provided above the vehicle of the meter display 18. An image generated by a projection device of a head-up display (first display section) (second display section) (vehicle display device) (hereinafter, HUD) 28 (see FIG. 2) provided on the vehicle 10 is projected onto the display area HA. ​​As shown in FIG. 2, the HUD 28 is connected to the display control ECU 26. Therefore, information related to the vehicle speed of the vehicle 10 is displayed in the display area HA as shown in FIG. 5.

[0039] As shown in FIG. 1, a steering wheel 22 is rotatably supported on the instrument panel 16. The steering wheel 22 includes a rim portion 22A, a hub portion 22B, and spoke portions 22C1, 22C2, and 22C3. The hub portion 22B is provided on the inner periphery of the substantially annular rim portion 22A. The inner periphery of the rim portion 22A and the hub portion 22B are connected by three spoke portions 22C1, 22C2, and 22C3. A steering switch 33R is provided on the right spoke portion 22C1, and a steering switch 33L is provided on the left spoke portion 22C2. The steering switch 33R includes a right first switch 34R, a right second switch 36R, and a right function changeover switch 38R, which are independent of each other. The steering switch 33L includes a left first switch 34L, a left second switch 36L, and a left function changeover switch 38L, which are independent of each other.

[0040] The right first switch 34R, which is substantially rectangular, can be swung around a swing center (not shown) provided at the center. The right first switch 34R includes a first input section 34R1, a second input section 34R2, a third input section 34R3, and a fourth input section 34R4, which are located on the outer periphery side of the swing center. The first input section 34R1, the second input section 34R2, the third input section 34R3, and the fourth input section 34R4 have different functions. When the right first switch 34R swings, the first input section 34R1, the second input section 34R2, the third input section 34R3, and the fourth input section 34R4 move by a small distance between the initial position and the pressed position in a direction substantially parallel to the front-rear direction. When no external force is applied to the right first switch 34R, or when part of the occupant's body contacts the first input portion 34R1, the second input portion 34R2, the third input portion 34R3 or the fourth input portion 34R4, the first input portion 34R1, the second input portion 34R2, the third input portion 34R3 and the fourth input portion 34R4 are located in their initial positions.

[0041] In this specification, a part of the occupant's body contacts the first input unit 34R1 means that a part of the occupant's body contacts the first input unit 34R1 and the first input unit 34R1 is located at the initial position. The same applies to the second input unit 34R2, the third input unit 34R3, the fourth input unit 34R4, the right second switch 36R (first input unit 36R1, second input unit 36R2), the right function changeover switch 38R, the left first switch 34L (first input unit 34L1, second input unit 34L2, third input unit 34L3, fourth input unit 34L4), the left second switch 36L (first input unit 36L1, second input unit 36L2), and the left function changeover switch 38L.

[0042] Furthermore, in this specification, a part of the body refers to a part of the body to which an electrostatic sensor described later reacts. For example, a hand is a part of the body. Furthermore, an operation in which a part of the occupant's body touches at least one of the first right switch 34R, the second right switch 36R, the right function changeover switch 38R, the first left switch 34L, the second left switch 36L, and the left function changeover switch 38L may be referred to as a "first operation."

[0043] The right first switch 34R is equipped with an electrostatic sensor (not shown). When a part of the occupant's body touches the first input section 34R1, the second input section 34R2, the third input section 34R3, or the fourth input section 34R4 of the right first switch 34R, the function of the first input section 34R1, the second input section 34R2, the third input section 34R3, or the fourth input section 34R4 that the part of the body touches is selected. Furthermore, when the first input section 34R1, the second input section 34R2, the third input section 34R3, or the fourth input section 34R4 is moved to the pressed position by a part of the occupant's body, the selected function is executed. Similar electrostatic sensors are also installed in the right second switch 36R, the right function changeover switch 38R, the left first switch 34L, the left second switch 36L, and the left function changeover switch 38L.

[0044] The right second switch 36R, which is substantially rectangular and located to the left of the right first switch 34R, can be swung around a swing center (not shown) provided at the center of the switch. The right second switch 36R has a first input section 36R1 and a second input section 36R2 located above and below the swing center, respectively. The first input section 36R1 and the second input section 36R2 have different functions. When the right second switch 36R swings, the first input section 36R1 and the second input section 36R2 move a small distance between the initial position and the pressed position in a direction substantially parallel to the front-rear direction. When no external force is applied to the right second switch 36R, or when a part of the occupant's body contacts the first input section 36R1 or the second input section 36R2, the first input section 36R1 and the second input section 36R2 are located at the initial position.

[0045] The right function changeover switch 38R located below the right first switch 34R and the right second switch 36R is a switch for changing over the functions assigned to the right first switch 34R and the right second switch 36R. The right function changeover switch 38R can move between an initial position and a depressed position by a small distance in a direction substantially parallel to the front-rear direction. When no external force is applied to the right function changeover switch 38R, or when a part of the occupant's body contacts the right function changeover switch 38R, the right function changeover switch 38R is located at the initial position. When the right function changeover switch 38R is moved to the depressed position for a time equal to or less than a predetermined threshold, the functions assigned to the right first switch 34R and the right second switch 36R are changed over. Data related to the threshold is recorded, for example, in the ROM 26B or storage 26D of the display control ECU 26 described later. In this embodiment, as an example, two functions are assigned to each of the first input section 34R1, the second input section 34R2, the third input section 34R3, and the fourth input section 34R4 of the right first switch 34R, and the first input section 36R1 and the second input section 36R2 of the right second switch 36R. When the right function changeover switch 38R is positioned in the pressed position for a time period equal to or shorter than a threshold value, the functions assigned to the right first switch 34R (the first input section 34R1, the second input section 34R2, the third input section 34R3, and the fourth input section 34R4) and the right second switch 36R (the first input section 36R1 and the second input section 36R2) are changed.

[0046] Furthermore, a part of the occupant's body may keep the right function changeover switch 38R or the left function changeover switch 38L in the depressed position for a time exceeding the threshold value. Such an operation on the right function changeover switch 38R and the left function changeover switch 38L may be referred to as a "second operation." When the second operation is performed on the right function changeover switch 38R, the functions assigned to the right first switch 34R and the right second switch 36R are not switched. Similarly, when the second operation is performed on the left function changeover switch 38L, the functions assigned to the left first switch 34L and the left second switch 36L are not switched. Note that when an operation is performed to move the right function changeover switch 38R to the depressed position, the first operation is performed on the right function changeover switch 38R in the initial stage of the operation. Similarly, when an operation is performed to move the left function changeover switch 38L to the depressed position, the first operation is performed on the left function changeover switch 38L in the initial stage of the operation.

[0047] The left first switch 34L has the same configuration as the right first switch 34R, except that it is symmetrical. That is, the left first switch 34L can swing around a swing center, and has a first input part 34L1, a second input part 34L2, a third input part 34L3, and a fourth input part 34L4 that can move between an initial position and a pressed position. The first input part 34L1, the second input part 34L2, the third input part 34L3, and the fourth input part 34L4 have different functions from each other.

[0048] The left second switch 36L has the same configuration as the right second switch 36R, except for being symmetrical. That is, the left second switch 36L is swingable around a swing center, and includes a first input section 36L1 and a second input section 36L2. The first input section 36L1 and the second input section 36L2 have different functions.

[0049] The left function changeover switch 38L has the same configuration as the right function changeover switch 38R, except for being symmetrical. That is, the left function changeover switch 38L is a switch for changing over the functions assigned to the first input section 34L1, the second input section 34L2, the third input section 34L3, and the fourth input section 34L4 of the left first switch 34L, and the first input section 36L1 and the second input section 36L2 of the left second switch 36L.

[0050] The vehicle 10 is provided with a display control ECU (Electronic Control Unit) 26 shown in Fig. 2. The display control ECU 26 includes a CPU (Central Processing Unit: Processor) 26A, a ROM (Read Only Memory) 26B, a RAM (Random Access Memory) 26C, a storage 26D, a communication interface (communication I / F) 26E, and an input / output interface (input / output I / F) 26F. Each component is connected to each other so as to be able to communicate with each other via an internal bus 26Z.

[0051] The CPU 26A is a central processing unit that executes various programs and controls each part. That is, the CPU 26A reads a program from the ROM 26B or the storage 26D, and executes the program using the RAM 26C as a working area. The CPU 26A also controls each of the above components and performs various arithmetic processing according to the program recorded in the ROM 26B or the storage 26D.

[0052] The ROM 26B stores various programs and various data. The RAM 26C temporarily stores programs or data as a working area. The storage 26D is a non-temporary recording medium configured with an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs including an operating system and various data. In this embodiment, the ROM 26B or the storage 26D stores programs for performing input control processing and the like.

[0053] The communication interface 26E is an interface for the display control ECU 26 to communicate with an external server and other devices. For the communication interface 26E, standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark) are used.

[0054] The first right switch 34R, the second right switch 36R, the right function changeover switch 38R, the first left switch 34L, the second left switch 36L, the left function changeover switch 38L, and the HUD 28 are electrically connected to the input / output I / F 26F.

[0055] The display control ECU 26 is electrically connected to the driving assistance ECU 32. The driving assistance ECU 32 includes a CPU (processor), a ROM, a RAM, a storage, a communication interface (communication I / F), and an input / output interface (input / output I / F). These components are connected to each other via an internal bus so that they can communicate with each other. The driving assistance ECU 32 of this embodiment is connected to various actuators for driving the sensor group 20, the brake device, the steering device, and the internal combustion engine (drive source). The driving assistance ECU 32 may be connected to an electric motor (drive source). The driving assistance ECU 32 has a function of causing the vehicle 10 to execute driving assistance control by controlling the actuator group (and the electric motor). The "driving assistance control" in this specification includes driving assistance control of driving levels 1 to 5 defined by the Society of Automotive Engineers (SAE). The driving assistance control includes, for example, adaptive cruise control (ACC) and lane tracing assist (LTA).

[0056] The display control ECU 26 uses the above hardware resources to realize various functions. The functional configuration realized by the display control ECU 26 will be described with reference to FIG.

[0057] 3, the display control ECU 26 has, as functional components, a control mode acquisition unit 261, a function display unit 262, an operation acceptance unit 263, a function switching acceptance unit 264, and an automatic display unit 265. The control mode acquisition unit 261, the function display unit 262, the operation acceptance unit 263, the function switching acceptance unit 264, and the automatic display unit 265 are realized by the CPU 26A reading and executing a program stored in the ROM 26B or the storage 26D.

[0058] The control mode acquisition unit 261 acquires the details of the driving assistance control being executed by the driving assistance ECU 32 .

[0059] The function display unit 262 displays the functions assigned to the right first switch 34R, the right second switch 36R, the left first switch 34L, and the left second switch 36L in the display area HA. ​​For example, when the occupant's hand is in contact with the right first switch 34R, the right second switch 36R, or the right function changeover switch 38R, as shown in Figs. 6 and 7, the function display unit 262 continues to display the steering switch image 33RM in the display area HA. ​​When a part of the occupant's body is removed from the steering switch 33R, the function display unit 262 erases the steering switch image 33RM from the display area HA when a predetermined time has elapsed since the time of removal. This predetermined time is, for example, 5 seconds. The steering switch image 33RM includes a right first switch image 34RM, a right second switch image 36RM, and a right function changeover switch image 38RM, which respectively represent the right first switch 34R, the right second switch 36R, and the right function changeover switch 38R. Also, when a part of the occupant's body is in contact with the first left switch 34L, the second left switch 36L, or the left function changeover switch 38L, the function display unit 262 continues to display a steering switch image (not shown) that is symmetrical to the steering switch image 33RM in the display area HA. ​​When a part of the occupant's body is removed from the steering switch 33L, the function display unit 262 erases the steering switch image from the display area HA when a predetermined time has elapsed since the time of removal. This predetermined time is, for example, 5 seconds. Note that the display area HA does not simultaneously display both the steering switch image 33RM and the steering switch image corresponding to the left function changeover switch 38L. For example, when the steering switch image 33RM is displayed in the display area HA, if a part of the occupant's body is in contact with the first left switch 34L, the second left switch 36L, or the left function changeover switch 38L, the steering switch image 33RM is erased from the display area HA, and instead, the steering switch image corresponding to the left function changeover switch 38L is displayed.

[0060] When a part of the occupant's body does not touch the steering switch 33R and the steering switch 33L, the steering switch image 33RM and the steering switch image corresponding to the steering switch 33L are not displayed in the display area HA as shown in Fig. 5. In this case, only information related to the vehicle speed of the vehicle 10 is displayed in the display area HA.

[0061] In Fig. 6, the right first switch image 34RM includes a third input section image 34R3M representing the third input section 34R3 and a fourth input section image 34R4M representing the fourth input section 34R4. In this case, specific functions are assigned to the third input section 34R3 and the fourth input section 34R4. On the other hand, no function is assigned to the first input section 34R1 and the second input section 34R2. Therefore, in this case, the right first switch image 34RM does not include images representing the first input section 34R1 and the second input section 34R2.

[0062] In this case, the third input unit 34R3 is assigned a function for setting the distance between the vehicle 10 and the preceding vehicle. Therefore, when the steering switch image 33RM is displayed in the display area HA, if the occupant moves the third input unit 34R3 to the pressed position with a part of the body, the set value of the distance between the vehicles changes.

[0063] In this case, a function related to switching of the control mode is assigned to the fourth input unit 34R4. Therefore, when the steering switch image 33RM is displayed in the display area HA, if the occupant moves the fourth input unit 34R4 to the pressed position with a part of the body, the control mode of the vehicle 10 is switched.

[0064] The first input unit 36R1 is assigned a function for switching the radar cruise mode between an ON state and an OFF state, so that when the steering switch image 33RM is displayed in the display area HA, if the occupant moves the first input unit 36R1 to the pressed position with a part of the body, the radar cruise mode is switched between an ON state and an OFF state.

[0065] The second input unit 36R2 is assigned a function for switching the LTA between an ON state and an OFF state, so that when the steering switch image 33RM is displayed in the display area HA, if the occupant moves the second input unit 36R2 to the pressed position with a part of the body, the LTA is switched between an ON state and an OFF state.

[0066] The operation reception unit 263 receives inputs of the right first switch 34R, the right second switch 36R, the left first switch 34L, and the left second switch 36L. Specifically, when the right first switch 34R or the right second switch 36R is moved to the pressed position while the steering switch image 33RM is displayed in the display area HA, the operation reception unit 263 executes the function of the switch that has been moved to the pressed position. Also, when the left first switch 34L or the left second switch 36L is moved to the pressed position while the steering switch image corresponding to the steering switch 33L is displayed in the display area HA, the operation reception unit 263 executes the function of the switch that has been moved to the pressed position.

[0067] The function switching reception unit 264 receives an input from the right function switching switch 38R when the steering switch image 33RM is displayed in the display area HA. ​​Furthermore, the function switching reception unit 264 receives an input from the function switching switch 38L when the steering switch image corresponding to the steering switch 33L is displayed in the display area HA. ​​Specifically, the function switching reception unit 264 switches the functions of the right first switch 34R and the right second switch 36R when the right function switching switch 38R is positioned in the pressed position for a time period equal to or less than a threshold value in a state in which the steering switch image 33RM is displayed in the display area HA. ​​Furthermore, the function switching reception unit 264 switches the functions of the left first switch 34L and the left second switch 36L when the left function switching switch 38L is positioned in the pressed position for a time period equal to or less than a threshold value in a state in which the steering switch image corresponding to the steering switch 33L is displayed in the display area HA. ​​In this way, the right function switching switch 38R and the left function switching switch 38L are assigned functions for function switching.

[0068] For example, when the right function changeover switch 38R is placed in the depressed position for a time period equal to or shorter than a threshold value in the state of Fig. 6, the function display unit 262 changes the display area HA to the state of Fig. 7. That is, as shown in Fig. 7, the first input unit image 34R1M, the second input unit image 34R2M, the third input unit image 34R3M, and the fourth input unit image 34R4M are changed from the images shown in Fig. 6. Therefore, an occupant who sees the first input unit image 34R1M, the second input unit image 34R2M, the third input unit image 34R3M, and the fourth input unit image 34R4M can recognize that the functions assigned to the first input units 34R1, 34R2, the third input unit 34R3, and the fourth input unit 34R4 have been switched.

[0069] The automatic display unit 265 has a function of automatically displaying a predetermined message on the meter display 18 and the display area HA by controlling the meter display 18 and the HUD 28 when a predetermined condition is satisfied. FIG. 8 shows a message list 50 showing an example of a message generated by the automatic display unit 265. The message list 50 is recorded in the ROM 26B or the storage 26D. The message list 50 of this embodiment includes five messages. Furthermore, a priority order is set for these five messages. The higher the number (level) indicating the priority order, the higher the priority order. Furthermore, although not shown in the figure, a priority order is also set for the steering switch image 33RM displayed in the display area HA when the occupant performs a first operation on the steering switch 33R, and the steering switch image corresponding to the steering switch 33L displayed in the display area HA when the occupant performs a first operation on the steering switch 33L. The priority order of the steering switch image 33RM and the steering switch image corresponding to the steering switch 33L is level 2. Furthermore, in this embodiment, the priority order of level 2 is called a "standard priority order."

[0070] For example, when the above-mentioned predetermined condition is satisfied that the vehicle 10 has started a predetermined speed control, the automatic display unit 265 displays a message "Speed ​​control in progress" on the meter display 18 and the display area HA. ​​When the above-mentioned predetermined condition is satisfied that a preceding vehicle that was stopped starts moving while the vehicle 10 is executing ACC, the automatic display unit 265 displays a message "Preceding vehicle starts moving" on the meter display 18 and the display area HA. ​​When the above-mentioned predetermined condition is satisfied that a TTC (time to collision), which varies depending on the distance between the vehicle 10 and the preceding vehicle, becomes equal to or less than a first predetermined value, the automatic display unit 265 displays a message "Please press the brake" on the meter display 18 and the display area HA. ​​When the above-mentioned predetermined condition is satisfied that the TTC becomes equal to or less than a second predetermined value that is smaller than the first predetermined value, the automatic display unit 265 displays a message "Brake!" on the meter display 18 and the display area HA. ​​When the above-mentioned predetermined condition is satisfied that a predetermined component of the vehicle 10 has failed, the automatic display unit 265 displays a message "XX is broken." Note that this "XX" is the name of the component that has failed.

[0071] The set display time of each message displayed on the meter display 18 and the display area HA by the automatic display unit 265 is set for each message. That is, the set display time differs for each message. The set display time of each message is, for example, 5 to 10 seconds. When the set display time has elapsed, the automatic display unit 265 controls the meter display 18 and the HUD 28 to erase the message from the meter display 18 and the display area HA. ​​Note that the message is not limited to text. That is, images such as icons are also included in the message.

[0072] When the predetermined condition is met in this manner, the automatic display unit 265 automatically displays a predetermined message on the meter display 18 and the display area HA. ​​However, if a specific condition is met, the automatic display unit 265 erases the message displayed on the meter display 18 and the display area HA before the set display time has elapsed. The contents of the specific condition differ between the display area HA and the meter display 18. These specific conditions will be described below.

[0073] First, the specific condition of the display area HA will be described. As shown in Fig. 5, when the occupant performs a first operation on the steering switch 33R or the steering switch 33L while a message of a reference priority level or lower (level 2 or lower) is displayed in the display area HA by the automatic display unit 265, the specific condition of the display area HA is established. For example, as shown in Fig. 5, when the occupant performs a first operation on the steering switch 33R while a message of level 2 is displayed in the display area HA, the message of level 2 is erased from the display area HA by the HUD 28 controlled by the automatic display unit 265 and a steering switch image 33RM is displayed in the display area HA, as shown in Fig. 6.

[0074] Next, the specific condition of the meter display 18 will be described. As shown in Fig. 4, when the occupant performs a second operation on the right function changeover switch 38R while a message of a level 2 or lower priority level is being displayed on the meter display 18 by the automatic display unit 265, the specific condition of the meter display 18 is established. For example, as shown in Fig. 4, when the occupant keeps the right function changeover switch 38R in the pressed position for a time exceeding the threshold while a level 2 message is being displayed on the meter display 18, the level 2 message is erased from the meter display 18 controlled by the automatic display unit 265 (not shown). The threshold is, for example, 3 seconds. However, the threshold value may be a value different from 3 seconds.

[0075] (Action and Effects) Next, the operation and effects of this embodiment will be described.

[0076] Next, the process executed by the display control ECU 26 of the vehicle 10 will be described with reference to the flowchart of Fig. 11. The display control ECU 26 repeatedly executes the process of the flowchart shown in Fig. 11 every time a predetermined time elapses.

[0077] In step S10, the automatic display unit 265 of the display control ECU 26 determines whether or not a predetermined condition is met.

[0078] If the display control ECU 26 determines "Yes" in step S10, the process proceeds to step S11, where the automatic display unit 265 displays any one of the messages included in the message list 50 on the meter display 18 and in the display area HA.

[0079] After completing the process of step S11, the display control ECU 26 proceeds to step S12, where the automatic display unit 265 determines whether or not the occupant has performed a first operation on the steering switch 33R or the steering switch 33L.

[0080] If the display control ECU 26 determines "Yes" in step S12, the process proceeds to step S13, where the automatic display unit 265 determines whether or not a specific condition for the display area HA is satisfied. For example, when a message with a priority level equal to or lower than the reference priority level is displayed in the display area HA as shown in Fig. 5, if a first operation is performed on the steering switch 33R, the automatic display unit 265 determines "Yes" in step S13.

[0081] If the display control ECU 26 judges "Yes" in step S13, the process proceeds to step S14, where the automatic display unit 265 controls the HUD 28 to erase the above message from the display area HA and instead display a steering switch image 33RM in the display area HA as shown in FIG. 6.

[0082] On the other hand, when a message with a higher priority level than the reference priority level is displayed in the display area HA, the display control ECU 26 determines No in step S13. In this case, the message remains displayed in the display area HA, and the steering switch image 33RM or the steering switch image corresponding to the steering switch 33L is not displayed in the display area HA.

[0083] After completing the process of step S14, the display control ECU 26 proceeds to step S15, where the automatic display unit 265 determines whether or not the occupant has performed a second operation on the right function changeover switch 38R or the left function changeover switch 38L.

[0084] If the display control ECU 26 determines "Yes" in step S15, the process proceeds to step S16, where the automatic display unit 265 determines whether or not a specific condition of the meter display 18 is satisfied. For example, when a level 2 message is displayed on the meter display 18 as shown in Fig. 4, if a second operation is performed on the right function selector switch 38R, the automatic display unit 265 determines "Yes" in step S16.

[0085] If the result of the determination in step S16 is Yes, the display control ECU 26 proceeds to step S17, in which the automatic display unit 265 erases the message from the meter display 18.

[0086] On the other hand, when a message with a higher priority level than the reference priority level is being displayed on the meter display 18, the display control ECU 26 makes a negative determination in step S16. In this case, the message is left displayed on the meter display 18.

[0087] If the answer is No in step S12, S13, S15, or S16, the display control ECU 26 proceeds to step S18 and determines whether the set display time of the message displayed on the meter display 18 or the display area HA and the message displayed on the meter display 18 has elapsed.

[0088] If the display control ECU 26 determines "Yes" in step S18, the process proceeds to step S19, where the automatic display unit 265 erases the message being displayed on the meter display 18 or the display area HA and the message being displayed on the meter display 18.

[0089] When the result of the determination in step S10 is No, or when the processes of steps S17 and S19 are completed, the display control ECU 26 temporarily ends the process of the flowchart in FIG.

[0090] As described above, in this embodiment, when the occupant performs the first operation while a predetermined message is displayed on the meter display 18 and the display area HA, the message is erased from the display area HA. ​​Since the occupant can erase the message from the display area HA at their own will in this manner, the occupant is less likely to feel annoyed compared to a case in which the message displayed on the meter display 18 and the display area HA cannot be erased at the occupant's will.

[0091] Furthermore, the first operation is an operation of bringing a part of the occupant's body into contact with the steering switch 33R or the steering switch 33L provided on the steering wheel 22. Therefore, the occupant can easily erase the message from the display area HA.

[0092] Furthermore, in this embodiment, when the occupant performs a second operation different from the first operation, the message is erased from the meter display 18. Therefore, compared to a case where the message is erased from the meter display 18 and the display area HA when the first operation is performed, the possibility that the occupant will erroneously erase the message from the meter display 18 and the display area HA is low. In other words, even if the occupant erroneously performs the first operation, the message will remain displayed on the meter display 18 unless the second operation is performed. Therefore, in this case, the occupant can check the message generated by the automatic display unit 265 by looking at the meter display 18.

[0093] Furthermore, when the occupant moves the right function changeover switch 38R or the left function changeover switch 38L, which can move between an initial position and a depressed position, to the depressed position, the message is erased from the meter display 18. Therefore, the possibility that the occupant will erroneously erase the message from the meter display 18 is low, compared to when a part of the body comes into contact with the steering switch 33R or the steering switch 33L.

[0094] Furthermore, in this embodiment, when the occupant performs a first operation on the steering switch 33R or the steering switch 33L, the steering switch image 33RM or the steering switch image corresponding to the steering switch 33L is displayed in the display area HA. ​​Therefore, the occupant can recognize the positional relationship between the part of his / her body (e.g., a hand) that performed the first operation and the steering switch 33R or the steering switch 33L by looking at the display area HA.

[0095] Furthermore, in this embodiment, when a message (first message) whose priority is equal to or lower than the reference priority is displayed in the display area HA and the occupant performs a first operation, the message is erased from the display area HA and a steering switch image corresponding to the steering switch image 33RM or the steering switch 33L is displayed in the display area HA. ​​Therefore, in this case, the occupant can recognize the steering switch image corresponding to the steering switch image 33RM or the steering switch 33L whose priority is equal to or higher than the message by looking at the display area HA.

[0096] Furthermore, in this embodiment, when a occupant performs a first operation in a state in which a message (second message) having a higher priority than the reference priority is displayed in the display area HA, the message remains displayed in the display area HA, and the steering switch image corresponding to the steering switch image 33RM or the steering switch 33L is not displayed in the display area HA. ​​Therefore, in this case, the occupant can recognize the message having a higher priority than the steering switch image corresponding to the steering switch image 33RM or the steering switch 33L by looking at the display area HA.

[0097] Furthermore, in this embodiment, when the occupant performs the second operation while a message (third message) whose priority is equal to or lower than the reference priority is being displayed on the meter display 18, the message is erased from the meter display 18. Therefore, in this case, the occupant does not feel annoyed by the message displayed on the meter display 18.

[0098] Furthermore, in this embodiment, when the occupant performs the second operation while a message (fourth message) with a priority higher than the reference priority is being displayed on the meter display 18, the meter display 18 continues to display the message. Therefore, even if the occupant mistakenly performs the second operation, the occupant can recognize the message by looking at the meter display 18.

[0099] Furthermore, in this embodiment, the set display time of each message in the display area HA when the first operation is not performed, and the set display time of each message in the meter display 18 when the second operation is not performed are set for each message. Therefore, it is possible to make it difficult for the occupant to feel annoyed by the messages displayed on the meter display 18 and the display area HA.

[0100] The above describes the vehicle display control device, vehicle display device, vehicle, vehicle display control method, and program according to the embodiments. However, the design of the vehicle display control device, vehicle display device, vehicle, vehicle display control method, and program can be modified as appropriate without departing from the spirit of the present invention.

[0101] For example, the second operation may be an operation in which the occupant simultaneously places the right function changeover switch 38R and the left function changeover switch 38L in the pressed position with a part of the body.

[0102] The second operation may be an operation in which the occupant intermittently contacts the right function changeover switch 38R or the left function changeover switch 38L with a part of his / her body multiple times within a short period of time. In this case, the short period of time is, for example, one second, and the multiple times is, for example, three times.

[0103] As shown by phantom lines in FIG. 1, a cancel switch 60R and a cancel switch 60L may be provided on the steering wheel 22 in addition to the right function selector switch 38R and the left function selector switch 38L. The cancel switch 60R and the cancel switch 60L are also movable between an initial position and a pressed position. In this case, when the cancel switch 60R is moved to the pressed position by a part of the occupant's body, messages with priorities lower than the reference priority are erased from the meter display 18. Similarly, when the cancel switch 60L is moved to the pressed position by a part of the occupant's body, messages with priorities lower than the reference priority are erased from the meter display 18.

[0104] The meter display 18 may be a "first display section" in the claims, and the display area HA may be a "second display section" in the claims.

[0105] When the first operation is performed, a steering switch image corresponding to the steering switch 33RM or the steering switch 33L may be simultaneously displayed on the meter display 18 and in the display area HA.

[0106] The reference priority of the message displayed on the meter display 18 may be different from the reference priority of the message displayed in the display area HA. ​​For example, the reference priority of the message displayed in the display area HA may be set to the same priority level as the priority of the steering switch images corresponding to the steering switch image 33RM and the steering switch 33L, while the reference priority of the message displayed on the meter display 18 may be set to a different level from the priority of the steering switch images corresponding to the steering switch image 33RM and the steering switch 33L.

[0107] All messages included in the message list 50 may have the same set display time.

[0108] The specific condition of the meter display 18 may be omitted. In this case, step S16 in the flowchart of Fig. 11 is omitted. That is, if the determination in step S15 is Yes, the message is erased from the meter display 18 in step S17. [Explanation of symbols]
