Description

TECHNICAL FIELD

[0001] The present disclosure relates to a vehicle display control device, a vehicle display device, a vehicle, a vehicle display control method, and a storage medium. BACKGROUND

[0002] In Japanese Patent Application Publication No. 2017-087980, an invention is disclosed in which various information is displayed on a display provided in an instrument panel of a vehicle and a head-up display.

[0003] In the invention of Japanese Patent Application Publication No. 2017-087980, in order to avoid the occupant from becoming bored and to reduce the occupant's concern that the displayed information cannot be recognized, there is room for improvement in displaying information on the display provided in the instrument panel and the head-up display. SUMMARY

[0004] In view of the above, an object of the present disclosure is to obtain a vehicle display control device, a vehicle display device, a vehicle, a vehicle display control method, and a storage medium that avoid the occupant from becoming bored and reduce the occupant's concern that the displayed information cannot be recognized, and that enable a prescribed message to be displayed on a first display portion and a second display portion provided in a vehicle.

[0005] The vehicle display control device according to the first aspect of the present disclosure includes a processor that controls a first display portion provided in a vehicle and a second display portion that is a display portion different from the first display portion, such that when a first operation is performed by an occupant of the vehicle in a state in which a prescribed message is displayed on the first display portion and the second display portion, the message is eliminated from the first display portion, and the state in which the message is displayed on the second display portion is maintained.

[0006] In the vehicle display control device according to the first aspect of the present disclosure, when a first operation is performed by an occupant of the vehicle in a state in which a prescribed message is displayed on a first display portion and a second display portion provided in a vehicle, the message is eliminated from the first display portion. In the vehicle display control device according to the first aspect of the present disclosure, the occupant is thus able to eliminate the message from the first display portion at his or her own discretion, and therefore is less likely to become bored than in a case in which the occupant is unable to eliminate the message displayed on the first display portion and the second display portion in accordance with his or her own discretion.

[0007] Further, in the vehicle display control device according to the first aspect of the present disclosure, when a first operation is performed by an occupant of the vehicle in a state in which a prescribed message is displayed on a first display portion and a second display portion provided in a vehicle, the state in which the message is displayed on the second display portion is maintained. Therefore, even in a case in which the message is eliminated from the first display portion, the occupant is able to recognize the message displayed on the second display portion.

[0008] The display control device for a vehicle according to the second aspect of the present disclosure is configured to, on the basis of the first aspect of the present disclosure, regard a prescribed operation of a steering switch provided to a steering wheel of the vehicle as the first operation, and control the first display portion so that, when the occupant performs the first operation in a state in which the message is displayed on the first display portion and the second display portion, a steering switch image that indicates the steering switch is displayed.

[0009] In the second aspect of the present disclosure, the steering switch image that indicates the steering switch is displayed on the first display portion when the occupant performs the first operation on the steering switch. Therefore, the occupant can recognize the positional relationship between a part of his or her own body (for example, a hand) that performed the first operation and the steering switch by observing the first display portion.

[0010] The display control device for a vehicle according to the third aspect of the present disclosure is configured to, on the basis of the second aspect of the present disclosure, enable the first display portion to display a plurality of kinds of messages for which the priority order of display is determined, and control the first display portion so that, when the occupant performs the first operation in a state in which a message whose priority order is lower than that of the steering switch image, that is, a first message, is displayed on the first display portion, the first message is eliminated and the steering switch image is displayed, and when the occupant performs the first operation in a state in which a message whose priority order is higher than that of the steering switch image, that is, a second message, is displayed on the first display portion, the state in which the first message is displayed is maintained and the steering switch image is not displayed.

[0011] In the third aspect of the present disclosure, when the occupant performs the first operation in a state in which a message whose priority order is lower than that of the steering switch image, that is, a first message, is displayed on the first display portion, the first message is eliminated from the first display portion and the steering switch image is displayed on the first display portion. Therefore, in this case, the occupant can recognize the steering switch image whose priority order is higher than the first message by observing the first display portion.

[0012] Also, in the display control device for a vehicle according to the third aspect of the present disclosure, when the occupant performs the first operation in a state in which a message whose priority order is higher than that of the steering switch image, that is, a second message, is displayed on the first display portion, the state in which the first message is displayed on the first display portion is maintained and the steering switch image is not displayed on the first display portion. Therefore, in this case, the occupant can recognize the second message whose priority order is higher than that of the steering switch image by observing the first display portion.

[0013] The display control device for vehicle according to the fourth aspect of the present disclosure is configured to, in addition to the second or third aspect of the present disclosure, be such that the operation in which a part of the passenger's body contacts the steering switch is the first operation.

[0014] In the fourth aspect of the present disclosure, the message is eliminated from the first display after a part of the passenger's body contacts the steering switch. Therefore, the passenger can simply eliminate the message from the first display.

[0015] The display control device for vehicle according to the fifth aspect of the present disclosure is configured to, in addition to any one of the first to fourth aspects of the present disclosure, be such that the processor controls the second display so that when the passenger performs a second operation different from the first operation in a state in which the message is displayed on the second display, the message is eliminated from the second display.

[0016] In the fifth aspect of the present disclosure, the message is eliminated from the second display when the passenger performs the second operation different from the first operation. Therefore, compared to the case in which the message is eliminated from the first and second displays when the first operation is performed, the possibility that the passenger mistakenly eliminates the message from the first and second displays is low.

[0017] The display control device for vehicle according to the sixth aspect of the present disclosure is configured to, in addition to the fifth aspect of the present disclosure, be such that the second display can display a plurality of kinds of messages for which a display priority order is determined, and the second display is controlled so that when the passenger performs the second operation in a state in which a message having a priority order lower than a predetermined reference priority order, i.e., a third message, is displayed on the second display, the third message is eliminated from the second display, and when the passenger performs the second operation in a state in which a message having a priority order higher than the reference priority order, i.e., a fourth message, is displayed on the second display, the state in which the fourth message is displayed is maintained.

[0018] In the sixth aspect of the present disclosure, the third message is eliminated from the second display when the passenger performs the second operation in a state in which the third message, which is a message having a priority order lower than a predetermined reference priority order, is displayed on the second display. Therefore, in this case, the passenger does not become bored with the third message displayed on the second display.

[0019] Also, in the display control device for vehicle according to the sixth aspect of the present disclosure, when the occupant performs the second operation in a state where the message of a higher priority order than the reference priority order, i.e., the fourth message is displayed on the second display portion, the second display portion continues to display the fourth message. Therefore, even in a case where the occupant erroneously performs the second operation, the occupant can recognize the fourth message of a higher priority order by observing the second display portion.

[0020] The display control device for vehicle according to the seventh aspect of the present disclosure is configured to set, on the basis of the fifth or sixth aspect of the present disclosure, the set display time of each of the messages on the first display portion in a case where the first operation is not performed, and the set display time of each of the messages on the second display portion in a case where the second operation is not performed.

[0021] In the seventh aspect of the present disclosure, the set display time of each of the messages on the first display portion in a case where the first operation is not performed, and the set display time of each of the messages on the second display portion in a case where the second operation is not performed are set. Therefore, the occupant can be less likely to feel bored with the messages displayed on the first and second display portions.

[0022] The display control device for vehicle according to the eighth aspect of the present disclosure is configured to, on the basis of any one of the fifth to seventh aspects of the present disclosure, make the operation of moving a steering switch provided to a steering wheel of the vehicle and movable between an initial position and a pressed position to the pressed position the second operation.

[0023] In the eighth aspect of the present disclosure, the message is eliminated from the second display portion when the occupant performs the operation of moving the steering switch movable between the initial position and the pressed position to the pressed position. Therefore, compared to a case where the message is eliminated from the second display portion when a part of the body contacts the steering switch, the occupant is less likely to erroneously eliminate the message from the second display portion.

[0024] The display control device for vehicle according to the ninth aspect of the present disclosure is configured to, on the basis of the first to eighth aspects of the present disclosure, the first display portion be a head-up display.

[0025] In the ninth aspect of the present disclosure, the message displayed on the head-up display can be eliminated when the occupant performs the first operation.

[0026] The display control device for vehicle according to the tenth aspect of the present disclosure is configured to, on the basis of the first to ninth aspects of the present disclosure, the second display portion be a display provided inside the vehicle.

[0027] In the tenth aspect of the present disclosure, the display provided inside the vehicle can display the message.

[0028] The vehicle display device according to the 11th aspect of the present disclosure includes the first display portion, the second display portion, and the vehicle display control device according to the 1st to 10th aspects of the present disclosure.

[0029] The vehicle according to the 12th aspect of the present disclosure includes the vehicle display device according to the 11th aspect of the present disclosure.

[0030] The vehicle display control method according to the 13th aspect of the present disclosure includes controlling, by a processor, a first display portion provided in a vehicle and a second display portion different from the first display portion, such that when a first operation is performed by an occupant of the vehicle in a state in which a predetermined message is displayed on the first display portion and the second display portion, the message is eliminated from the first display portion, and a state in which the message is displayed on the second display portion is maintained.

[0031] The storage medium according to the 14th aspect of the present disclosure stores a program and is readable by a computer, and when the program is executed by a processor, the following step is performed: controlling, by the processor, a first display portion provided in a vehicle and a second display portion different from the first display portion, such that when a first operation is performed by an occupant of the vehicle in a state in which a predetermined message is displayed on the first display portion and the second display portion, the message is eliminated from the first display portion, and a state in which the message is displayed on the second display portion is maintained.

[0032] As described above, the vehicle display control device, the vehicle display device, the vehicle, the vehicle display control method, and the storage medium according to the present disclosure have an excellent effect of being able to display a predetermined message on a first display portion and a second display portion provided in a vehicle, while avoiding the occupant from easily feeling bored and reducing the occupant's concern that the displayed information cannot be recognized.

[0045] Hereinafter, embodiments of a vehicle display control device, a vehicle display device, a vehicle, a vehicle display control method, and a storage medium according to the present disclosure will be described with reference to the accompanying drawings.

[0046] As shown in Figure 1 , the vehicle 10 of the present embodiment is provided with a front windshield 14 and an instrument panel 16. A meter display (display) (first display portion) (second display portion) (vehicle display device) 18 is provided in the instrument panel 16. A sensor group 20 is provided in the upper portion of the inner side surface of the front windshield 14. The sensor group 20 includes at least one of a camera, a Laser Imaging Detection and Ranging (LIDAR) sensor, a positioning camera, and a millimeter wave radar sensor.

[0047] The meter display (MET) 18 provided in the instrument panel 16 is controlled by a display control ECU (vehicle display control device) (vehicle display device) 26 described later. The display control ECU 26 is connected to various meter devices mounted on the vehicle 10. Therefore, for example, as shown in Figure 4 , information on the vehicle speed of the vehicle 10 is displayed on the meter display 18.

[0048] A display region (1st display portion) (2nd display portion) HA is formed in the front windshield 14. The display region HA is provided on the vehicle upper side of the instrument cluster 18. An image generated by a projection device of a head-up display (1st display portion) (2nd display portion) (vehicle display device) (hereinafter, referred to as HUD) 28 (refer to Figure 2 ) provided in the vehicle 10 is projected on the display region HA. As shown in Figure 2 , the HUD 28 is connected to the display control ECU 26. Therefore, as shown in Figure 5 , information on the vehicle speed of the vehicle 10 is displayed in the display region HA.

[0049] As shown in Figure 1 , the steering wheel 22 is rotatably supported to the instrument panel 16. The steering wheel 22 has a rim portion 22A, a hub portion 22B, and spoke portions 22C1, 22C2, 22C3. The hub portion 22B is provided on the inner peripheral side of the substantially circular ring-shaped rim portion 22A. Further, the inner peripheral portion of the rim portion 22A and the hub portion 22B are linked by the three spoke portions 22C1, 22C2, 22C3. Moreover, a steering switch 33R is provided to the right side spoke portion 22C1, and a steering switch 33L is provided to the left side spoke portion 22C2. The steering switch 33R includes a right 1st switch 34R, a right 2nd switch 36R, and a right function switching switch 38R, which are independent from each other. The steering switch 33L includes a left 1st switch 34L, a left 2nd switch 36L, and a left function switching switch 38L, which are independent from each other.

[0050] The substantially rectangular right 1st switch 34R is able to swing with a swing center (omitted from the drawing) provided in the center portion thereof as a center. The right 1st switch 34R has a 1st input portion 34R1, a 2nd input portion 34R2, a 3rd input portion 34R3, and a 4th input portion 34R4, which are located on the outer peripheral side of the swing center. The 1st input portion 34R1, the 2nd input portion 34R2, the 3rd input portion 34R3, and the 4th input portion 34R4 have mutually different functions. By the right 1st switch 34R swinging, the 1st input portion 34R1, the 2nd input portion 34R2, the 3rd input portion 34R3, and the 4th input portion 34R4 move a slight distance in a direction substantially parallel to the front-rear direction between an initial position and a pressed position. When no external force is applied to the right 1st switch 34R, or when a part of the body of the occupant contacts the 1st input portion 34R1, the 2nd input portion 34R2, the 3rd input portion 34R3, or the 4th input portion 34R4, the 1st input portion 34R1, the 2nd input portion 34R2, the 3rd input portion 34R3, and the 4th input portion 34R4 are located at the initial position.

[0051] Further, in the present specification, the part of the passenger's body contacting the first input portion 34R1 means that the part of the passenger's body is contacting the first input portion 34R1 and the first input portion 34R1 is in the initial position. The same applies to the second input portion 34R2, the third input portion 34R3, the fourth input portion 34R4, the right second switch 36R (the first input portion 36R1, the second input portion 36R2), the right function switching switch 38R, the left first switch 34L (the first input portion 34L1, the second input portion 34L2, the third input portion 34L3, the fourth input portion 34L4), the left second switch 36L (the first input portion 36L1, the second input portion 36L2), and the left function switching switch 38L.

[0052] Further, in the present specification, the part of the body means the part of the body reacting to the electrostatic sensor described later. For example, the hand is the part of the body. Further, there is a case where the operation of contacting the part of the passenger's body to at least one of the right first switch 34R, the right second switch 36R, the right function switching switch 38R, the left first switch 34L, the left second switch 36L, and the left function switching switch 38L is referred to as the "first operation".

[0053] The right first switch 34R is equipped with an electrostatic sensor not shown. If the part of the passenger's body contacts the first input portion 34R1, the second input portion 34R2, the third input portion 34R3, or the fourth input portion 34R4 of the right first switch 34R, it becomes a state where the function possessed by the first input portion 34R1, the second input portion 34R2, the third input portion 34R3, or the fourth input portion 34R4 contacted by the part of the body is selected. Further, if the first input portion 34R1, the second input portion 34R2, the third input portion 34R3, or the fourth input portion 34R4 is moved to the pressed position by the part of the passenger's body, the selected function is executed. The same electrostatic sensor is also equipped in the right second switch 36R, the right function switching switch 38R, the left first switch 34L, the left second switch 36L, and the left function switching switch 38L.

[0054] The right second switch 36R, which is a substantially rectangular switch located to the left of the right first switch 34R, is capable of pivoting about a pivot center (not shown) provided in the center portion thereof. The right second switch 36R has a first input portion 36R1 and a second input portion 36R2 located on the upper side and the lower side of the pivot center, respectively. The first input portion 36R1 and the second input portion 36R2 have mutually different functions. By pivoting the right second switch 36R, the first input portion 36R1 and the second input portion 36R2 are moved by a slight distance in a direction substantially parallel to the front-rear direction between an initial position and a pressed position. 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 portion 36R1 or the second input portion 36R2, the first input portion 36R1 and the second input portion 36R2 are located at the initial position.

[0055] The right function switching switch 38R, which is a switch located below the right first switch 34R and the right second switch 36R, is a switch for switching the functions assigned to the right first switch 34R and the right second switch 36R. The right function switching switch 38R is capable of moving by a slight distance in a direction substantially parallel to the front-rear direction between an initial position and a pressed position. When no external force is applied to the right function switching switch 38R, or when a part of the occupant's body contacts the right function switching switch 38R, the right function switching switch 38R is located at the initial position. If the right function switching switch 38R is moved by a time below a prescribed threshold value toward the pressed position, the functions assigned to the right first switch 34R and the right second switch 36R are switched. Data regarding this threshold value is recorded, for example, in the ROM 26B or the storage device 26D of the display control ECU 26 described later. In the present embodiment, as an example, two functions are assigned to the first input portion 34R1, the second input portion 34R2, the third input portion 34R3, and the fourth input portion 34R4 of the right first switch 34R, and the first input portion 36R1 and the second input portion 36R2 of the right second switch 36R, respectively. If the right function switching switch 38R is located below the pressed position threshold value, the functions assigned to the right first switch 34R (the first input portion 34R1, the second input portion 34R2, the third input portion 34R3, and the fourth input portion 34R4) and the right second switch 36R (the first input portion 36R1 and the second input portion 36R2) are switched.

[0056] There is also a case where a part of the occupant's body keeps the right function switching switch 38R or the left function switching switch 38L in the pressed position for a time exceeding the threshold described above. There is a case where such operation on the right function switching switch 38R and the left function switching switch 38L is referred to as "second operation". In a case where the second operation is performed on the right function switching switch 38R, the functions assigned to the right first switch 34R and the right second switch 36R are not switched. Likewise, in a case where the second operation is performed on the left function switching switch 38L, the functions assigned to the left first switch 34L and the left second switch 36L are not switched. Further, in a case where an operation is performed to move the right function switching switch 38R to the pressed position, the first operation is performed on the right function switching switch 38R at an initial stage of the operation. Likewise, in a case where an operation is performed to move the left function switching switch 38L to the pressed position, the first operation is performed on the left function switching switch 38L at an initial stage of the operation.

[0057] The left first switch 34L is the same structure as the right first switch 34R except for points of bilateral symmetry. That is, the left first switch 34L is capable of oscillating about an oscillation center, and has a first input portion 34L1, a second input portion 34L2, a third input portion 34L3, and a fourth input portion 34L4, which are capable of moving between an initial position and a pressed position. The first input portion 34L1, the second input portion 34L2, the third input portion 34L3, and the fourth input portion 34L4 have mutually different functions.

[0058] The left second switch 36L is the same structure as the right second switch 36R except for points of bilateral symmetry. That is, the left second switch 36L is capable of oscillating about an oscillation center, and has a first input portion 36L1 and a second input portion 36L2. The first input portion 36L1 and the second input portion 36L2 have mutually different functions.

[0059] The left function switching switch 38L is the same structure as the right function switching switch 38R except for points of bilateral symmetry. That is, the left function switching switch 38L is a switch for switching the functions assigned to the first input portion 34L1, the second input portion 34L2, the third input portion 34L3, and the fourth input portion 34L4 of the left first switch 34L, and the first input portion 36L1 and the second input portion 36L2 of the left second switch 36L.

[0060] In the vehicle 10, the right function switching switch 38R and the left function switching switch 38L are provided in the vicinity of the right first switch 34R and the left first switch 34L, respectively. Figure 2A display control ECU (Electronic Control Unit) 26 is shown. The display control ECU 26 is configured to include a CPU (Central Processing Unit) 26A, a ROM (ReadOnly Memory) 26B, a RAM (Random Access Memory) 26C, a storage device 26D, a communication interface (communication I / F) 26E, and an input / output interface (input / output I / F) 26F. The respective structures are communicably connected to each other via an internal bus 26Z.

[0061] The CPU 26A is a central arithmetic processing unit that executes various programs and controls the respective structures. That is, the CPU 26A reads out a program from the ROM 26B or the storage device 26D and executes the program using the RAM 26C as a work area. In addition, the CPU 26A performs the control of the respective structures and various arithmetic processing in accordance with the program recorded in the ROM 26B or the storage device 26D.

[0062] The ROM 26B stores various programs and various data. The RAM 26C temporarily stores a program or data as a work area. The storage device 26D is configured by a HDD (Hard Disk Drive) or a SSD (Solid State Drive) and is a non-transitory recording medium (storage medium) that stores various programs including an operating system and various data. In the present embodiment, a program and the like for performing input control processing are stored in the ROM 26B or the storage device 26D.

[0063] The communication interface 26E is an interface for communication of the display control ECU 26 with an external server and other devices. The communication interface 26E uses, for example, a standard such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), Wi-Fi (registered trademark), and the like.

[0064] The input / output I / F 26F is electrically connected to the right first switch 34R, the right second switch 36R, the right function switching switch 38R, the left first switch 34L, the left second switch 36L, the left function switching switch 38L, and the HUD 28.

[0065] The display control ECU 26 is electrically connected to the drive assist ECU 32. The drive assist ECU 32 is configured to include a CPU (processor), a ROM, a RAM, a storage device, a communication interface (communication I / F), and an input / output interface (input / output I / F). These structures are communicably connected to each other via an internal bus. The drive assist ECU 32 of the present embodiment is connected to the sensor group 20, and various actuators for driving the brake device, the steering device, and the internal combustion engine (drive source). The drive assist ECU 32 can also be connected to an electric motor (drive source). The drive assist ECU 32 has a function of causing the vehicle 10 to perform drive assist control by controlling the above-described actuator group (and the electric motor). The "drive assist control" in the present specification includes drive assist control of the drive levels of levels 1 to 5 defined by SAE (Society of Automotive Engineers). The drive assist control includes, for example, ACC (adaptive cruise control) and LTA (lane tracking assist).

[0066] The display control ECU 26 implements various functions using the above-described hardware resources. The functions implemented by the display control ECU 26 will be described below with reference to Figure 3 The functional structure of the display control ECU 26 will be described.

[0067] As shown in Figure 3 , the display control ECU 26 has, as a functional structure, a control mode acquisition section 261, a function display section 262, an operation acceptance section 263, a function switch acceptance section 264, and an automatic display section 265. The control mode acquisition section 261, the function display section 262, the operation acceptance section 263, the function switch acceptance section 264, and the automatic display section 265 are implemented by the CPU 26A reading and executing a program stored in the ROM 26B or the storage device 26D.

[0068] The control mode acquisition section 261 acquires the content of the drive assist control being performed by the drive assist ECU 32.

[0069] The function display section 262 causes 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 to be displayed in the display area HA. For example, when the hand of the occupant comes into contact with the right first switch 34R, the right second switch 36R, or the right function switch 38R, the function display section 262 causes the function assigned to the right first switch 34R, the right second switch 36R, or the right function switch 38R to be displayed in the display area HA, as shown in Figure 6 and Figure 7As shown, the function display section 262 causes the steering switch image 33RM to be continuously displayed in the display region HA. If a part of the passenger's body departs from the steering switch 33R, the function display section 262 eliminates the steering switch image 33RM from the display region HA after a prescribed time elapses from the time of departure. The prescribed time is, for example, 5 seconds. The steering switch image 33RM includes a right first switch image 34RM that represents the right first switch 34R, a right second switch image 36RM that represents the right second switch 36R, and a right function switch image 38RM that represents the right function switch 38R. In addition, when a part of the passenger's body contacts the left first switch 34L, the left second switch 36L, or the left function switch 38L, the function display section 262 causes a steering switch image (omitted from illustration) that is left-right symmetrical with the steering switch image 33RM to be continuously displayed in the display region HA. If a part of the passenger's body departs from the steering switch 33L, the function display section 262 eliminates the steering switch image from the display region HA after a prescribed time elapses from the time of departure. The prescribed time is, for example, 5 seconds. Furthermore, both the steering switch image 33RM and a steering switch image corresponding to the left function switch 38L are not displayed simultaneously in the display region HA. For example, if a part of the passenger's body contacts the left first switch 34L, the left second switch 36L, or the left function switch 38L while the steering switch image 33RM is displayed in the display region HA, the steering switch image 33RM is eliminated from the display region HA, and a steering switch image corresponding to the left function switch 38L is displayed instead.

[0070] In a case where a part of the passenger's body does not contact the steering switch 33R and the steering switch 33L, as shown in Figure 5 , the steering switch image 33RM and a steering switch image corresponding to the steering switch 33L are not displayed in the display region HA. In this case, only information about the vehicle speed of the vehicle 10 is shown in the display region HA.

[0071] In Figure 6 , the right first switch image 34RM includes a third input portion image 34R3M that represents the third input portion 34R3 and a fourth input portion image 34R4M that represents the fourth input portion 34R4. In this case, specific functions are assigned to the third input portion 34R3 and the fourth input portion 34R4, respectively. On the other hand, no functions are assigned to the first input portion 34R1 and the second input portion 34R2, respectively. Therefore, in this case, the right first switch image 34RM does not include images that represent the first input portion 34R1 and the second input portion 34R2.

[0072] In this case, the 3rd input section 34R3 is assigned a function for setting a vehicle distance between the vehicle 10 and the preceding vehicle. Therefore, if a part of the occupant's body moves the 3rd input section 34R3 to the pressed position while the steering switch image 33RM is displayed in the display region HA, the value of the set vehicle distance is changed.

[0073] In this case, the 4th input section 34R4 is assigned a function for switching a control mode. Therefore, if a part of the occupant's body moves the 4th input section 34R4 to the pressed position while the steering switch image 33RM is displayed in the display region HA, the control mode of the vehicle 10 is switched.

[0074] The 1st input section 36R1 is assigned a function for switching the radar cruise mode to an on state and an off state. Therefore, if a part of the occupant's body moves the 1st input section 36R1 to the pressed position while the steering switch image 33RM is displayed in the display region HA, the radar cruise mode is switched to the on state and the off state.

[0075] The 2nd input section 36R2 is assigned a function for switching the LTA to an on state and an off state. Therefore, if a part of the occupant's body moves the 2nd input section 36R2 to the pressed position while the steering switch image 33RM is displayed in the display region HA, the LTA is switched to the on state and the off state.

[0076] The operation accepting section 263 accepts inputs of the right 1st switch 34R, the right 2nd switch 36R, the left 1st switch 34L, and the left 2nd switch 36L. Specifically, when the steering switch image 33RM is displayed in the display region HA, the operation accepting section 263 executes the function of the switch moved to the pressed position when the right 1st switch 34R or the right 2nd switch 36R is moved to the pressed position. In addition, when the steering switch image corresponding to the steering switch 33L is displayed in the display region HA, the operation accepting section 263 executes the function of the switch moved to the pressed position when the left 1st switch 34L or the left 2nd switch 36L is moved to the pressed position.

[0077] When the turn signal switch image 33RM is displayed in the display area HA, the function switching receiving unit 264 receives input from the right function switch 38R. Furthermore, when the turn signal switch image corresponding to the turn signal switch 33L is displayed in the display area HA, the function switching receiving unit 264 receives input from the function switch 38L. Specifically, when the turn signal switch image 33RM is displayed in the display area HA, and the right function switch 38R is held below a pressed position threshold, the function switching receiving unit 264 switches the functions of the first right switch 34R and the second right switch 36R. Additionally, when the turn signal switch image corresponding to the turn signal switch 33L is displayed in the display area HA, and the left function switch 38L is held below a pressed position threshold, the function switching receiving unit 264 switches the functions of the first left switch 34L and the second left switch 36L. Thus, functions for switching are assigned to the right function switch 38R and the left function switch 38L.

[0078] For example, if in Figure 6 If the right function switch 38R is kept below the press position threshold for a certain period of time in the state, the display area HA will be moved to the function display unit 262. Figure 7 The state. That is, as... Figure 7 As shown, from Figure 6 The images shown are the first input image 34R1M, the second input image 34R2M, the third input image 34R3M, and the fourth input image 34R4M. Therefore, the occupants who see the first input image 34R1M, the second input image 34R2M, the third input image 34R3M, and the fourth input image 34R4M can recognize that the functions assigned to the first input 34R1, 34R2, the third input 34R3, and the fourth input 34R4 have been switched.

[0079] The automatic display unit 265 has the function of automatically displaying a specified message on the instrument display 18 and the display area HA by controlling the instrument display 18 and the HUD 28 when specified conditions are met. Figure 8A message list 50 representing examples of messages generated by the automatic display section 265 is shown. The message list 50 is recorded in the ROM 26B or the storage device 26D. The message list 50 of the present embodiment includes five messages. And a priority order is set for the five messages. The larger the number (rank) representing the priority order, the higher the priority order. And, although not shown, a priority order is also set for the steering switch image 33RM displayed in the display region HA when the occupant performs the first operation on the steering switch 33R, and the steering switch image corresponding to the steering switch 33L displayed in the display region HA when the occupant performs the first operation on the steering switch 33L. The priority order of the steering switch image corresponding to the steering switch image 33RM and the steering switch 33L is rank 2. And, in the present embodiment, the priority order of rank 2 is referred to as a "reference priority order".

[0080] For example, when the above-described prescribed condition that the vehicle 10 has started a prescribed speed control is established, the automatic display section 265 causes the message "Speed Control" to be displayed in the instrument panel display 18 and the display region HA. Also, during the period when the vehicle 10 is executing ACC, when the above-described prescribed condition that a preceding vehicle that is stopped has started is established, the automatic display section 265 causes the message "Preceding Vehicle Started" to be displayed in the instrument panel display 18 and the display region HA. Also, when the above-described prescribed condition that the TTC (time to collision) that varies in accordance with the vehicle distance between the vehicle 10 and a preceding vehicle has become equal to or less than a first prescribed value is established, the automatic display section 265 causes the message "Please Step on Brake" to be displayed in the instrument panel display 18 and the display region HA. Also, when the above-described prescribed condition that the TTC has become equal to or less than a second prescribed value that is smaller than the first prescribed value is established, the automatic display section 265 causes the message "Brake!" to be displayed in the instrument panel display 18 and the display region HA. Also, when the above-described prescribed condition that a prescribed structural component possessed by the vehicle 10 has failed is established, the message "〇〇 Failure" is displayed. Here, the "〇〇" is the name of the structural component that has failed.

[0081] The set display time of each message displayed in the instrument panel display 18 and the display region HA by the automatic display section 265 is set in accordance with each message. That is, the set display time is made different for each message. The set display time of each message is, for example, 5 to 10 seconds. If the set display time elapses, the automatic display section 265 eliminates the message from the instrument panel display 18 and the display region HA by controlling the instrument panel display 18 and the HUD 28. Also, the message is not limited to text. That is, an image such as an icon is also included in the message.

[0082] Thus, when the prescribed condition is satisfied, the automatic display section 265 causes the prescribed message to be automatically displayed on the meter display 18 and the display region HA. Among others, in the case where a specific condition is satisfied, the automatic display section 265 eliminates the message displayed on the meter display 18 and the display region HA before the set display time elapses. The content of the specific condition differs between the display region HA and the meter display 18. Hereinafter, the specific conditions of these will be described.

[0083] First, the specific condition of the display region HA will be described. As shown in Figure 5 , the specific condition of the display region HA is satisfied when the occupant performs the first operation on the steering switch 33R or the steering switch 33L during the period in which the automatic display section 265 displays the message below the reference priority order (rank 2 or lower) on the display region HA. For example, as shown in Figure 5 , if the occupant performs the first operation on the steering switch 33R during the period in which the rank 2 message is displayed on the display region HA, as shown in Figure 6 , the rank 2 message is eliminated from the display region HA and the steering switch image 33RM is displayed on the display region HA by the HUD 28 controlled by the automatic display section 265.

[0084] Next, the specific condition of the meter display 18 will be described. As shown in Figure 4 , the specific condition of the meter display 18 is satisfied when the occupant performs the second operation on the right function switch 38R during the period in which the automatic display section 265 displays the message below the reference priority order (rank 2 or lower) on the meter display 18. For example, as shown in Figure 4 , if the occupant causes the right function switch 38R to be continuously located at the pressed position for a time exceeding the threshold value during the period in which the rank 2 message is displayed on the meter display 18, the rank 2 message is eliminated from the meter display 18 controlled by the automatic display section 265 (omitted from the illustration). The threshold value is, for example, 3 seconds. Among others, the value of the threshold value can be a size different from 3 seconds.

[0085] (Action and Effect)

[0086] Next, the action and effect of the present embodiment will be described.

[0087] Next, the processing performed by the display control ECU 26 of the vehicle 10 will be described using the flowchart of Figure 11 . The display control ECU 26 repeatedly performs the processing of the flowchart shown in Figure 11 every prescribed time.

[0088] In step S10, the automatic display section 265 of the display control ECU 26 determines whether or not a prescribed condition is satisfied.

[0089] The display control ECU 26 that has determined YES in step S10 proceeds to step SIl, and the automatic display section 265 causes any one of the messages included in the message list 50 to be displayed on the meter display 18 and the display region HA.

[0090] The display control ECU 26 that has completed the processing of step SIl proceeds to step S12, and the automatic display section 265 determines whether the occupant has performed the first operation on the steering switch 33R or the steering switch 33L.

[0091] The display control ECU 26 that has determined YES in step S12 proceeds to step S13, and the automatic display section 265 determines whether the specific condition of the display region HA is satisfied. For example, if the first operation is performed on the steering switch 33R while a message of a priority order lower than the reference priority order is displayed on the display region HA as shown in Figure 5 YES in step S13.

[0092] The display control ECU 26 that has determined YES in step S13 proceeds to step S14, and the HUD 28 is controlled by the automatic display section 265 to eliminate the above-described message from the display region HA, and instead the steering switch image 33RM is caused to be displayed on the display region HA as shown in Figure 6

[0093] On the other hand, when a message of a priority order higher than the reference priority order is displayed on the display region HA, the display control ECU 26 determines NO in step S13. In this case, the state in which the message is displayed on the display region HA is maintained, and the steering switch image 33RM or the steering switch image corresponding to the steering switch 33L is not displayed on the display region HA.

[0094] The display control ECU 26 that has completed the processing of step S14 proceeds to step S15, and the automatic display section 265 determines whether the occupant has performed the second operation on the right function switch 38R or the left function switch 38L.

[0095] The display control ECU 26 that has determined YES in step S15 proceeds to step S16, and the automatic display section 265 determines whether the specific condition of the meter display 18 is satisfied. For example, if the second operation is performed on the right function switch 38R while a message of the level 2 is displayed on the meter display 18 as shown in Figure 4 YES in step S16.

[0096] The display control ECU 26 that has determined YES in step S16 proceeds to step S17, and the automatic display section 265 eliminates the message from the meter display 18.

[0097] ​On the other hand, when the message of the priority order higher than the reference priority order is displayed on the instrument display 18, the display control ECU 26 determines NO in step S16. In this case, the state that the message is displayed on the instrument display 18 is maintained unchanged.

[0098] When the determination is NO in step S12, S13, S15, or S16, the display control ECU 26 proceeds to step S18, and determines whether or not the set display time of the message displayed on the instrument display 18 or the messages displayed on the display region HA and the instrument display 18 has elapsed.

[0099] The display control ECU 26 that determines YES in step S18 proceeds to step S19, and the automatic display section 265 cancels the message displayed on the instrument display 18 or the messages displayed on the display region HA and the instrument display 18.

[0100] When the determination is NO in step S10, or when the processing of step S17, S19 is completed, the display control ECU 26 temporarily ends the processing of the flowchart of FIG. 10. Figure 11

[0101] As described above, in the present embodiment, when the occupant performs the first operation in the state that the prescribed message is displayed on the instrument display 18 and the display region HA, the message is canceled from the display region HA. Thus, the occupant can cancel the message from the display region HA at his or her own will, and therefore, the occupant is less likely to feel bored than in the case where the message displayed on the instrument display 18 and the display region HA cannot be canceled according to the occupant's will.

[0102] Further, the first operation is an operation of contacting a part of the occupant's body with the steering switch 33R or 33L provided to the steering wheel 22. Therefore, the occupant can cancel the message from the display region HA simply.

[0103] Further, in the present embodiment, when the occupant performs the second operation different from the first operation, the message is canceled from the instrument display 18. Therefore, the occupant is less likely to cancel the message from the instrument display 18 and the display region HA by mistake than in the case where the message is canceled from the instrument display 18 and the display region HA when the first operation is performed. That is, even if the occupant performs the first operation by mistake, as long as the second operation is not performed, the state that the message is displayed on the instrument display 18 is maintained unchanged. Therefore, in this case, the occupant can confirm the message generated by the automatic display section 265 by observing the instrument display 18.

[0104] ​Also, when the occupant moves the right function switch 38R or the left function switch 38L which can be moved between the initial position and the pressed position to the pressed position, the message is eliminated from the instrument display 18. Therefore, compared to the case where the message is eliminated from the instrument display 18 when a part of the body contacts the steering switch 33R or the steering switch 33L, the possibility that the occupant erroneously eliminates the message from the instrument display 18 is low.

[0105] Also, in the present embodiment, when the occupant performs the 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 region HA. Therefore, the occupant can recognize the positional relationship between the part of the body (for example, the hand) of the occupant who performed the first operation and the steering switch 33R or the steering switch 33L by observing the display region HA.

[0106] Also, in the present embodiment, when the occupant performs the first operation in a state where the message (first message) whose priority order is lower than the reference priority order is displayed in the display region HA, the message is eliminated from the display region HA and the steering switch image 33RM or the steering switch image corresponding to the steering switch 33L is displayed in the display region HA. Therefore, in this case, the occupant can recognize the steering switch image 33RM or the steering switch image corresponding to the steering switch 33L whose priority order is higher than the message by observing the display region HA.

[0107] Also, in the present embodiment, when the occupant performs the first operation in a state where the message (second message) whose priority order is higher than the reference priority order is displayed in the display region HA, the state where the message is displayed in the display region HA is maintained, and the steering switch image 33RM or the steering switch image corresponding to the steering switch 33L is not displayed in the display region HA. Therefore, in this case, the occupant can recognize the message whose priority order is higher than the steering switch image 33RM or the steering switch image corresponding to the steering switch 33L by observing the display region HA.

[0108] Also, in the present embodiment, when the occupant performs the second operation in a state where the message (third message) whose priority order is lower than the reference priority order is displayed in the instrument display 18, the message is eliminated from the instrument display 18. Therefore, in this case, the occupant does not feel tired of the message displayed in the instrument display 18.

[0109] Also, in the present embodiment, when the occupant performs the second operation in a state where the message (the fourth message) having a higher priority order than the reference priority order is displayed on the instrument display 18, the instrument display 18 continues to display the message. Therefore, even in a case where the occupant erroneously performs the second operation, the occupant can recognize the message by observing the instrument display 18.

[0110] Also, in the present embodiment, the set display time of each message in the display region HA in a case where the first operation is not performed, and the set display time of each message in the instrument display 18 in a case where the second operation is not performed are set for each message. Therefore, it is possible to make the occupant less likely to feel tired of the messages displayed on the instrument display 18 and the display region HA.

[0111] The vehicle display control device, the vehicle display device, the vehicle, the vehicle display control method, and the storage medium according to the present embodiment have been described above, but the vehicle display control device, the vehicle display device, the vehicle, the vehicle display control method, and the storage medium can be appropriately designed to change within a range not departing from the gist of the present disclosure.

[0112] For example, an operation in which the occupant causes the right function switch 38R and the left function switch 38L to be simultaneously located at the pressed position by a part of the body can also be the second operation.

[0113] In addition, an operation in which a part of the occupant's body repeatedly contacts the right function switch 38R or the left function switch 38L for a short time can also be the second operation. The short time in this case is, for example, one second, and the number of times is, for example, three.

[0114] As indicated by a hypothetical line in Figure 1 The cancel switch 60R and the cancel switch 60L can also be provided separately from the right function switch 38R and the left function switch 38L on the steering wheel 22. The cancel switch 60R and the cancel switch 60L can also be 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, the messages having the priority order lower than the reference priority order are eliminated from the instrument display 18. Similarly, when the cancel switch 60L is moved to the pressed position by a part of the occupant's body, the messages having the priority order lower than the reference priority order are eliminated from the instrument display 18.

[0115] The instrument display 18 can be the "first display portion" of the claim, and the display region HA can be the "second display portion" of the claim.

[0116] It is also possible to configure such that, when the first operation is performed, the steering switch image 33RM or the steering switch image corresponding to the steering switch 33L is displayed on both the instrument display 18 and the display area HA.

[0117] It is also possible to make the reference priority order of the message displayed on the instrument display 18 different from the reference priority order of the message displayed on the display area HA. For example, it is also possible to configure such that the reference priority order of the message displayed on the display area HA is the same level of priority order as the priority order of the steering switch image 33RM and the steering switch image corresponding to the steering switch 33L, and the reference priority order of the message displayed on the instrument display 18 is the different level from the priority order of the steering switch image 33RM and the steering switch image corresponding to the steering switch 33L.

[0118] It is also possible to configure such that the set display time of all the messages included in the message list 50 is the same.

[0119] It is also possible to omit the specific condition of the instrument display 18. In this case, the step S16 of the flowchart is omitted. Figure 11 When the determination in step S15 is YES, the message is eliminated from the instrument display 18 in step S17.
