[0009] (Embodiment) Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that various modifications applicable to one embodiment may be hindered from being understood if they are introduced in the middle of a series of explanations relating to the embodiment. Therefore, the modifications will be explained together after the series of explanations relating to the embodiment, rather than in the middle of the series of explanations relating to the embodiment.

[0010] (In-vehicle system) Referring to FIG. 1, the vehicle 1 is a so-called four-wheeled automobile, and includes a vehicle body 2 that is substantially rectangular in plan view when the vehicle 1 is viewed from vertically above. For convenience in the following description, the concepts of "front," "rear," "left," "right," "up," and "down" for the vehicle 1 are defined as indicated by arrows in FIG. 1. These directional concepts are based on the driver, who is an occupant P, riding in the vehicle 1 while the vehicle is traveling forward (i.e., while the vehicle is traveling in a shift range other than reverse). The front-to-rear direction is synonymous with the vehicle's overall length direction. The left-to-right direction is synonymous with the vehicle's width direction. The up-to-down direction is synonymous with the vehicle's height direction. The vehicle's overall length direction is a direction perpendicular to the vehicle's width direction and perpendicular to the vehicle's height direction. The vehicle's height direction is a direction that defines the vehicle height of the vehicle 1 and is a direction parallel to the direction of gravity when the vehicle 1 is stably placed on a horizontal surface in a drivable state.

[0011] The front of the vehicle cabin 3, which is the interior space of the vehicle body 2 where the occupant P sits, is covered by a front windshield 4. The front windshield 4 is formed into a plate shape from translucent glass or synthetic resin. The front windshield 4 is tilted so that the upper end is located further rearward than the lower end in a side view seen from a line of sight parallel to the vehicle width direction.

[0012] A dashboard 5 is disposed below the front windshield 4 within the vehicle interior 3. A steering wheel 6 is attached to a steering column (not shown) that extends from a predetermined position on the dashboard 5 in the vehicle width direction toward the interior of the vehicle interior 3. The steering wheel 6 is provided in a position directly facing the driver's seat 7, i.e., a position directly facing the occupant riding position PB for the driver. The occupant riding position PB refers to the position of the upper body of the occupant P within the vehicle interior 3 when the occupant P is sitting in the seat 7 in a normal seated position.

[0013] An in-vehicle display device 8 is mounted on the dashboard 5. When mounted on the vehicle 1, the in-vehicle display device 8 is configured to display various information related to driving of the vehicle 1, such as vehicle speed, mileage, remaining driving range, current time, estimated time of arrival at the destination, etc., in a manner that is visible to the occupants P, including the driver. That is, the in-vehicle display device 8 is configured to perform some or all of the functions of a meter panel, a navigation display panel, an in-vehicle infotainment display panel, etc. In this embodiment, the in-vehicle display device 8 is configured as a flexible display such as an organic light-emitting diode display. A "flexible display" is a thin-plate or film-like display device that is configured to be bendable (i.e., foldable) along linear bending lines (i.e., folding lines) perpendicular to the thickness direction. The configuration of the in-vehicle display device 8 will be described in detail later.

[0014] A vehicle 1 is equipped with an in-vehicle system 10. The vehicle 1 equipped with the in-vehicle system 10 will be referred to as the "host vehicle" hereinafter. The in-vehicle system 10 is configured to be able to perform various controls when the host vehicle is being driven and various associated display operations. The in-vehicle system 10 is configured to configure an in-vehicle network that complies with a predetermined communication standard such as CAN (internationally registered trademark: international registration number 1048262A). CAN (internationally registered trademark) is an abbreviation for Controller Area Network.

[0015] The in-vehicle system 10 is configured to control the display state of the in-vehicle display device 8 using a display control device 11 in accordance with the driving state and driving environment of the vehicle. The "display state" includes whether or not a display element is displayed and the display form. The "display form" includes not only the display position but also various factors that affect the visibility of the display element (e.g., brightness, saturation, hue, line diameter, display size, blinking, animation, etc.). Specifically, referring to FIG. 2 , the in-vehicle system 10 includes, as components related to display control of the in-vehicle display device 8, the display control device 11, a camera 12, an object detection sensor 13, a vehicle state sensor 14, a navigation device 15, and a driving control device 16.

[0016] The display control device 11 is configured as an HCU. HCU is an abbreviation for HMI Control Unit. HMI is an abbreviation for Human Machine Interface. Specifically, the display control device 11 is configured as a so-called in-vehicle computer equipped with a processor and memory programmed to execute one or more functions embodied by a computer program. The display control device 11 is configured to control the display state of the in-vehicle display device 8 based on various information acquired from the camera 12, object detection sensor 13, vehicle state sensor 14, navigation device 15, and driving control device 16.

[0017] The camera 12 is provided so as to be able to capture images of the surroundings of the vehicle, at least images of the area in front of and to the sides of the vehicle. Specifically, the camera 12 is a digital camera device equipped with an image sensor such as a CCD or CMOS. CCD stands for Charge Coupled Device. CMOS stands for Complementary Metal Oxide Semiconductor.

[0018] The object detection sensor 13 is provided so as to be able to detect objects around the vehicle. Specifically, the object detection sensor 13 is configured so as to be able to detect moving and stationary objects within a predetermined detection range around the vehicle. "Moving objects" include pedestrians, cyclists, animals, and other vehicles in operation. "Stationary objects" include objects fallen on the road, guardrails, curbs, parked vehicles, road signs, road markings, roadside structures (e.g., walls, buildings, etc.), etc. Moving and stationary objects are included in "targets."

[0019] In this embodiment, the in-vehicle system 10 includes an object detection sensor 13 such as a radar sensor or an ultrasonic sensor. The radar sensor is a millimeter-wave radar sensor, a submillimeter-wave radar sensor, or a laser radar sensor configured to transmit and receive radar waves, and is mounted on the front of the vehicle body 2 of the vehicle. The radar sensor is configured to output a signal corresponding to the position and relative velocity of a reflection point. A "reflection point" is a point on the surface of an object around the vehicle that is estimated to have reflected radar waves. The "relative velocity" is the velocity of the reflection point, i.e., the object that reflected the radar waves, relative to the vehicle. In other words, the object detection sensor 13 is a general term for various sensors, other than the camera 12, that detect objects around the vehicle, for the sake of simplicity of illustration and description. The object detection sensor 13 may also be referred to as an "ADAS sensor." ADAS stands for Advanced Driver-Assistance Systems.

[0020] The vehicle condition sensor 14 is configured to detect the driving condition and driving environment of the vehicle. The "driving condition" includes various quantities related to the driving operation state by the driver or the driving control device 16, such as accelerator opening, braking amount, shift position, and steering angle. The "driving condition" also includes physical quantities related to the behavior of the vehicle, such as vehicle speed, angular velocity, longitudinal acceleration, and lateral acceleration. The "driving environment" includes natural environment factors such as outside temperature, rainfall, and illuminance. In other words, the vehicle condition sensor 14 is a collective term for various sensors, such as an accelerator opening sensor, steering angle sensor, wheel speed sensor, angular velocity sensor, acceleration sensor, outside temperature sensor, raindrop sensor, and illuminance sensor, for the sake of simplicity of illustration and explanation.

[0021] The navigation device 15 is configured to calculate the vehicle's position and the route the vehicle will take based on map information and positioning information from positioning satellites. The "vehicle position" is the current position of the vehicle on the map information. The "route" is the planned route the vehicle will take from the vehicle's position to the destination.

[0022] The driving control device 16 is configured to execute a predetermined driving assistance operation based on various information acquired from the camera 12, the object detection sensor 13, the vehicle state sensor 14, and the navigation device 15. The "predetermined driving assistance operation" includes, for example, various operations related to Level 4 "highly automated driving," Level 3 "conditional automated driving," Level 2 "partially automated driving," or Level 1 "driving assistance" in the automated driving levels defined by the Society of Automotive Engineers. The driving control device 16 is also configured to be able to provide the display control device 11 with information to be provided to the occupant P regarding the driving assistance operation, such as information regarding the execution or possibility of collision avoidance braking.

[0023] (In-vehicle display device) FIG. 3 shows the appearance of the in-vehicle display device 8 from the line of sight of a driver seated in a normal seating position in the driver's seat when the vehicle 1 is a so-called left-hand drive vehicle. The arrows indicating the concepts of "front," "rear," "left," "right," "up," and "down" shown in FIG. 3 are drawn to be consistent with those shown in FIG. 1. Furthermore, the passenger seating position PB in FIG. 3 is intended to roughly indicate the seating position of the driver in the vehicle width direction when the driver is seated in a normal seating position in the driver's seat. The same applies to FIG. 4 and subsequent figures.

[0024] The in-vehicle display device 8 includes a front display unit 81, a left side side display unit 82, a right side side display unit 83, a left additional display unit 84, and a right additional display unit 85. The right additional display unit 85 includes an additional front display unit 85a and an outer display unit 85b. The front display unit 81, the left side side display unit 82, the right side display unit 83, the left additional display unit 84, and the right additional display unit 85 are each part of the in-vehicle display device 8, which is a flexible display configured to be bendable, and are arranged in an arrangement direction along the vehicle width direction (i.e., the left-right direction in FIG. 3). The arrangement direction of the front display unit 81, the left side side display unit 82, the right side display unit 83, the left additional display unit 84, and the right additional display unit 85 will hereinafter be referred to simply as the "arrangement direction." The in-vehicle display device 8 is divided by multiple bends 86 into a front display section 81, a left side display section 82, a right side display section 83, a left additional display section 84, an additional front display section 85a, and an outer display section 85b.

[0025] The front display unit 81 is provided so as to face the driver's passenger seating position PB. The front display unit 81 has a width direction along the arrangement direction. In this embodiment, the front display unit 81 is formed in a substantially trapezoidal shape with the lower base longer than the upper base when viewed from the front. The front display unit 81 is provided so that its height direction is slightly inclined with respect to the vehicle height direction. Specifically, the front display unit 81 is arranged so that its lower end is closer to the driver's passenger seating position PB than its upper end.

[0026] The left side display unit 82, serving as a side display unit adjacent to the front display unit 81 in the arrangement direction, is provided on the left side of the front display unit 81 with respect to the driver's passenger seating position PB. The left side display unit 82 is formed in a substantially parallelogram shape when viewed from the front. A left side bent portion 86a, which is a bent portion 86 formed by bending a flexible display in a bendable direction, is provided between the front display unit 81 and the left side display unit 82. The left side bent portion 86a is formed so as to be inclined with respect to the height and width directions of the front display unit 81. That is, the left side bent portion 86a is provided as an oblique bent portion formed by bending the flexible display obliquely with respect to the arrangement direction. Specifically, the left side bent portion 86a is formed "upward and to the right" so that the lower end is positioned outward relative to the upper end, i.e., on the left side in the drawing. In this embodiment, the left side bent portion 86a is formed in a valley fold shape that is concave toward the driver's passenger seating position PB. The left side display section 82 extends from the left bent section 86a toward the front side, that is, diagonally rearward to the left.

[0027] The right side display unit 83, serving as a side display unit adjacent to the front display unit 81 in the arrangement direction, is provided to the right of the front display unit 81 with respect to the driver's seating position PB. The right side display unit 83 is formed in a substantially parallelogram shape when viewed from the front. A right side bent portion 86b, which is a bent portion 86, is provided between the front display unit 81 and the right side display unit 83. The right side bent portion 86b is formed so as to be inclined with respect to the height and width directions of the front display unit 81. That is, the right side bent portion 86b is provided as an oblique bent portion obtained by bending the flexible display obliquely with respect to the arrangement direction. Specifically, the right side bent portion 86b is formed in a "left-upward" shape so that the lower end is positioned more outward than the upper end, i.e., on the right side in the figure. In this embodiment, the right side bent portion 86b is formed in a valley-folded shape that is concave toward the driver's seating position PB. The right side display unit 83 extends forward from the right side bent portion 86b, i.e., diagonally rearward to the right.

[0028] In this way, the left side side display unit 82 is bent at the left bend portion 86a so as to face a different direction from the front side display unit 81. Similarly, the right side side display unit 83 is bent at the right bend portion 86b so as to face a different direction from the front side display unit 81. Specifically, the front side display unit 81 is provided so as to face approximately rearward. In contrast, the left side side display unit 82 is provided so as to face diagonally rearward to the right. Furthermore, the right side side display unit 83 is provided so as to face diagonally rearward to the left. In other words, the front side display unit 81, the left side side display unit 82, and the right side side display unit 83 are all directed toward the driver's passenger seating position PB. The front side display unit 81, the left side side display unit 82, and the right side side display unit 83 provided on either side of it, form a curved display that is concave toward the driver's passenger seating position PB.

[0029] The left additional display unit 84, which serves as an additional display unit adjacent to the left side side display unit 82 in the arrangement direction, extends outward, i.e., further left, from the left end of the left side side display unit 82. The left additional display unit 84 is provided so as to face substantially rearward. Between the left side side display unit 82 and the left additional display unit 84, there is provided a left additional bent unit 86c, which is an additional bent unit formed in a mountain fold shape that convexly faces the driver's passenger seating position PB. The left additional bent unit 86c is formed so as to be inclined with respect to the height and width directions of the left additional display unit 84. Specifically, the left additional bent unit 86c is formed "upward to the right" so that the lower end is positioned further outward, i.e., on the left side in the figure, than the upper end.

[0030] The right additional display unit 85, which serves as an additional display unit adjacent to the right side display unit 83 in the arrangement direction, extends outward, i.e., further to the right, from the right end of the right side display unit 83. A right additional bent unit 86d, which is an additional bent unit formed in a mountain fold shape that convexly extends toward the driver's passenger seating position PB, is provided between the right side display unit 83 and the right additional display unit 85. The right additional bent unit 86d is formed so as to be inclined with respect to the height and width directions of the additional front display unit 85a, which is the portion of the right additional display unit 85 adjacent to the right side display unit 83. Specifically, the right additional bent unit 86d is formed "upward to the left" so that the lower end is positioned more outward, i.e., right side, than the upper end.

[0031] The additional front display unit 85a is disposed so as to face substantially rearward. The outer display unit 85b is disposed adjacent to the additional front display unit 85a in the arrangement direction. In this embodiment, the outer display unit 85b faces outward, i.e., diagonally rearward to the right, so that the display screen faces the passenger seat, making it easy for the passenger to see and operate. The "passenger seat" refers to the seat 7 adjacent to the driver's seat in the vehicle width direction. Between the additional front display unit 85a and the outer display unit 85b, an outer bent portion 86e is provided, which is formed in a mountain-folded shape that convexly faces the driver's passenger seat position PB. The outer bent portion 86e is formed so as to be inclined with respect to the height and width directions of the additional front display unit 85a. Specifically, the outer bent portion 86e is formed "upward to the left" so that the lower end is positioned outward, i.e., to the right in the figure, relative to the upper end.

[0032] (Operation overview) An outline of the operation of the in-vehicle system 10 according to this embodiment will be described below, along with the effects achieved by the configuration according to this embodiment.

[0033] The display control device 11 controls the display state of the in-vehicle display device 8 based on various information acquired from the camera 12, the object detection sensor 13, the vehicle state sensor 14, the navigation device 15, and the driving control device 16. As a result, various information related to driving of the vehicle, such as vehicle speed, mileage, remaining driving range, current time, estimated time of arrival at the destination, etc., is displayed on each of the front display unit 81, the left side display unit 82, the right side display unit 83, the left additional display unit 84, and the right additional display unit 85 of the in-vehicle display device 8.

[0034] Recently, ADAS functions have become widespread in vehicles 1, and various sensing devices have been installed in vehicles 1 for ADAS operation. During ADAS operation, information necessary for the driver's recognition and decision-making is presented to the driver using an instrument panel, an in-vehicle infotainment display panel, or the like. For example, from the driver's line of sight, surrounding objects such as other vehicles or pedestrians may be difficult to see due to being in a blind spot. In such cases, information notification using an instrument panel, an in-vehicle infotainment display panel, or the like becomes important, and it is necessary to convey necessary information to occupants P, including the driver, more quickly, more intuitively, and more accurately to effectively support the driver's recognition and decision-making. In this regard, with the two-dimensional image display provided by conventional instrument panels, etc., the image display must be converted into three-dimensional object position information in the brain, and there is room for improvement in performance from the perspective of intuitive information recognition.

[0035] In this regard, the present embodiment utilizes the properties of the in-vehicle display device 8 as a flexible display to more quickly, intuitively, and accurately convey necessary information to an occupant P, such as a driver. Specifically, by folding the flexible display so that the front display unit 81, the left side display unit 82, and the right side display unit 83 indicate the front and left and right directions of the vehicle, respectively, it becomes possible to intuitively represent the relationship with the actual scenery. More specifically, for example, the left side display unit 82 can display targets located in a lateral area that is located to the left of the front area located in the direction of travel of the vehicle, relative to the occupant seating position PB. Similarly, the right side display unit 83 can display targets located in a lateral area that is located to the right of the front area located in the direction of travel of the vehicle, relative to the occupant seating position PB.

[0036] FIG. 4 shows a display example when another vehicle is present in the blind spot on the left side of the vehicle. In the display example shown in FIG. 4, the front display unit 81 displays information corresponding to the driving state of the vehicle, such as vehicle speed and driving assistance status (e.g., lane keeping assist is in progress, etc.). The left side display unit 82, which is to the left of the front display unit 81, displays information that another vehicle is present in the blind spot on the left side of the vehicle. The left additional display unit 84 displays a touch operation screen for operating audio and vehicle functions (e.g., adjusting vehicle speed in cruise control, etc.). The additional front display unit 85a displays map information and navigation information around the vehicle. The outer display unit 85b displays a touch operation screen for operating the air conditioning vent on the passenger side, such as adjusting the air temperature.

[0037] 5 shows an example of a display when a pedestrian is present in the blind spot on the right side of the vehicle. In the example of the display shown in FIG. 5, information indicating that a pedestrian is present in the blind spot on the right side of the vehicle is displayed on the right side display unit 83, which is to the right of the front display unit 81. The displays on the front display unit 81, the left additional display unit 84, and the right additional display unit 85 are the same as those in the example of FIG. 4.

[0038] As described above, according to this embodiment, a display device that envelops the occupant P, i.e., the driver, seated at the occupant seating position PB facing the front display unit 81, displays information about targets present around the vehicle at a display position corresponding to their relative position relative to the vehicle. This allows the information about the targets to be displayed in a manner that is more intuitively recognizable. Furthermore, the additional display units, i.e., the left additional display unit 84 and the right additional display unit 85, are positioned closer to the front display unit 81, i.e., closer to the occupant seating position PB. The front display unit 81, which displays information corresponding to the vehicle's driving status, such as vehicle speed and driving assistance status, is positioned further forward, thereby reducing the need for eye movement and focus shifts between checking the outside of the vehicle and checking the front display unit 81, allowing the driver to recognize information about the vehicle's surroundings in a shorter time. Meanwhile, since the additional display unit is a touch-operated screen for operation, locating it closer to the occupant seating position PB facilitates touch operation. As described above, this structure allows both visibility of information corresponding to the driving status and operability of the touch-operated screen to be achieved on a single display.

[0039] FIG. 6 shows a display example for creating a sense of speed while the vehicle is traveling on a highway. In the display example shown in FIG. 6, main information corresponding to the traveling state of the vehicle, such as vehicle speed, is displayed in the approximate center of the front display unit 81. The front display unit 81, the left side display unit 82, and the right side display unit 83 then display an animation of graphics extending radially from the display of the main information to create a sense of speed. The displays on the left additional display unit 84 and the right side additional display unit 85 are similar to those shown in FIG. 4 and other examples. According to this embodiment, by using a display device that envelops the occupant P, i.e., the driver, seated at the occupant seating position PB directly facing the front display unit 81, a display for creating a sense of speed is performed, further enhancing the visual effect and further increasing the driving pleasure of the occupant P.

[0040] In this embodiment, the in-vehicle display device 8 is divided into multiple display sections by a diagonally folded bent section 86. With this configuration, it is possible to provide any display section in any shape and orientation by utilizing the configuration as a flexible display. Therefore, it is possible to realize displays with irregular shapes that differ from existing shapes such as conventional rectangular or oval shapes while suppressing manufacturing costs. It also becomes possible to increase the degree of freedom in the design of the in-vehicle display device 8.

[0041] (Variation) The present invention is not limited to the above-described embodiment. Therefore, the above-described embodiment can be modified as appropriate. Representative modifications will be described below. In the following description of the modifications, differences from the above-described embodiment will be mainly described. Furthermore, identical or equivalent parts between the above-described embodiment and the modifications are given the same reference numerals. Therefore, in the following description of the modifications, the description of the above-described embodiment can be used as appropriate for components having the same reference numerals as those in the above-described embodiment, unless there is a technical contradiction or special additional explanation.

[0042] The present invention is not limited to the specific device configurations shown in the above embodiments. That is, for example, the vehicle 1 is not limited to a standard automobile. Specifically, the vehicle 1 may be a large automobile such as a cargo truck. There is no particular limitation on the number of wheels, and the vehicle 1 may be a three-wheeled automobile, or a six- or eight-wheeled automobile such as a cargo truck. The type of vehicle 1 may be a conventional automobile equipped with only an internal combustion engine, an electric automobile or a fuel cell vehicle without an internal combustion engine, or a so-called hybrid vehicle. The shape and structure of the body 2 of the vehicle 1 are also not limited to a box shape, i.e., a substantially rectangular shape in a plan view. There are also no particular limitations on the use of the vehicle 1, the number of occupants, etc.

[0043] There are no particular limitations on the presence or absence of a dashboard 5, the position of the steering wheel 6, etc. That is, the vehicle 1 may be a so-called left-hand drive vehicle or a so-called right-hand drive vehicle. Alternatively, the steering wheel 6 and the driver's seat may be provided in the center in the vehicle width direction. The driver may be any vehicle occupant who is in charge of or performs a dynamic driving task. In other words, as long as the driver is able to perform driving operations, there are no particular limitations on the seating position of the driver. In addition, any operating device such as a joystick may be used instead of or in addition to the steering wheel 6.

[0044] The communication standard for the in-vehicle system 10 may be other than CAN (internationally registered trademark), such as FlexRay (internationally registered trademark). The communication standard for the in-vehicle system 10 is not limited to one type. For example, the in-vehicle system 10 may have a sub-network line that complies with a communication standard such as LIN. LIN is an abbreviation for Local Interconnect Network.

[0045] Camera 12 is not limited to a type that is fixedly attached to vehicle body 2 or vehicle interior 3. That is, for example, a camera equipped in a so-called aftermarket drive recorder may be used as camera 12. Alternatively, for example, a camera equipped in a mobile terminal brought into vehicle interior 3 by occupant P (for example, an external camera equipped in a so-called smartphone) may be used as camera 12. In this case, instead of a driver status monitor (not shown) for detecting the driver's viewpoint or a camera for capturing images inside the vehicle interior, another camera equipped in the mobile terminal (for example, an internal camera equipped in a so-called smartphone) may be used.
