DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of an information display device according to the present disclosure will be described using an information display device for a vehicle, such as an automobile, with reference to the accompanying drawings. The present disclosure can be applied to an information display device for a vehicle, such as an information display device mounted on a moving body including an automobile, agricultural machinery, or construction machinery.

[0009] In the following, to facilitate understanding of the configuration of the information presentation device, as shown in each figure, the direction that a driver D seated in the driver's seat of a vehicle looks in is referred to as "front (Fr. in the figure)" and the opposite side is referred to as "rear (Re. in the figure)." Furthermore, the up-down direction (To., Bo. in the figure) corresponds to the top-to-bottom direction of the vehicle. Furthermore, the left-to-right direction (L, R in the figure) corresponds to the direction in which the vehicle turns right or left.

[0010] (First embodiment) As shown in Figures 1 and 2, the vehicle has at least a driver's seat where a driver D sits, a passenger seat next to the driver's seat, a windshield (windshield) C1 of the vehicle located in front of the driver D, a dashboard C2 located in front of the driver D and below the windshield C1, A-pillars C3 located on the left and right of the windshield C1, and side mirrors C4 located on the left and right of the A-pillar C3 outside the vehicle.

[0011] As shown in Figures 1 and 2, the information presentation device has a first display 1, a second display 2, a third display 3, a fourth display 4, a fifth display 5, a sixth display 6, and a seventh display 7.

[0012] The first display 1, the third display 3, and the fourth display 4 are arranged in the dashboard C2 facing the windshield C1, and are arranged in the order of the third display 3, the fourth display 4, and the first display 1 as they move from the windshield C1 side toward the driver D.

[0013] The first display 1 has a first display unit 1V that displays first information 1a. The first display 1 is a well-known head-up display (HUD) that includes a light source 1L made of an LED (light emitting diode), a display that generates image light that is the first information 1a using the light from the light source 1L, a reflective member made of a plane mirror or concave mirror that magnifies and reflects the image light, a circuit board that controls these components, and a case that houses these components.

[0014] The first display 1 projects and reflects image light onto the light-transmitting portion C1a of the windshield C1, which is visually recognized as a virtual image by the driver D. The first display unit 1V is the surface on which this virtual image is displayed, and is located 4 m ahead of the driver D.

[0015] The first information 1a (virtual object or content) includes, for example, vehicle speed, engine RPM, remaining fuel, ODO / TRIP, fuel economy, outside temperature, navigation (driving direction) information, active cruise control display, traffic signs (speed limit, lane information, stop, no overtaking, no entry, etc.), warnings notifying of proximity to surrounding vehicles, overtaking vehicle warning, lane departure warning, handbrake display, seatbelt warning, other driving-related information, incoming phone and email notifications, text information such as music, radio and TV, current time, etc.

[0016] The second display 2 has a second display unit 2V that displays second information 2a at a position closer to the driver D than the first display unit 1V. Although not shown, the second display 2 is a display that includes a light source made up of a so-called three-color LED, a design plate having a design facing the light source, a circuit board that mounts and controls the light source, and a case that houses these.

[0017] The second display 2 is disposed inside the mirror surface of the side mirror C4. The second display unit 2V has a design that emits light when exposed to light from a light source, and this light is transmitted through the mirror surface and is recognized as a real image that is directly visible to the driver D. The second display unit 2V is this mirror surface, and is located 1 m ahead of the driver D in the forward direction.

[0018] The third display 3 has a third display section 3V that displays third information 3a at a position between the first display section 1V and the second display section 2V. The third display 3 is a display that includes a light source 3L made up of a so-called three-color LED, a light-emitting section that receives light from the light source 3L and emits light, a circuit board that mounts and controls the light source 3L, and a case that houses these.

[0019] The third display 3 is formed in a line shape extending along the vicinity of the lower edge of the windshield C1 so as to connect the lower parts of the left and right A-pillars C3. In other words, the third display 3 is disposed in front of the driver's seat and also in front of the passenger seat. The third display 3 projects and reflects display light emitted by the light-emitting unit onto the translucent portion C1a of the windshield C1, which is visually recognized by the driver D as a virtual image. The third display unit 3V is the surface on which this virtual image is displayed and is located 1.5 m ahead of the driver D. The third display unit 3V is displayed below the first display unit 1V.

[0020] The third display 3 has a plurality of light sources 3L arranged in a line at equal intervals. The color and brightness of each light source 3L can be controlled as desired. When one of the plurality of light sources 3L of the third display 3 emits light, only the light-emitting section corresponding to the emitting light source 3L emits light in a dot pattern, thereby presenting a virtual spotlight image to the driver D. Furthermore, when multiple adjacent light sources 3L of the third display 3 are turned on simultaneously, only the light-emitting section corresponding to the emitting light source 3L emits light in a line pattern, thereby presenting a virtual bar graph image to the driver D.

[0021] As shown in FIG. 2, the third display 3 can display a gradation by lighting the light source 3L on the far left side (the side facing the left A-pillar C3) at the highest brightness and lighting the light source 3L so that the brightness decreases as it moves toward the opposite side, facing the A-pillar C3.

[0022] The fourth display device 4 has a fourth display unit 4V that displays fourth information 4a at a position between the first display unit 1V and the third display unit 3V, and is visually recognized as a virtual image by the driver D. The fourth display device 4 is a display device that includes a light source 4L consisting of a so-called three-color LED, a light guide that guides the light of the light source 4L, a design plate that has multiple round designs facing the light source 4L, a circuit board that mounts and controls the light source 4L, and a case that houses these.

[0023] The fourth display 4 is disposed between the first display 1 and the third display 3, and in two locations, one to the right and one to the left of the first display 1. The fourth display 4 projects and reflects display light emitted by the design of the decorative plate onto the translucent portion C1a of the windshield C1, which is visible to the driver D as a virtual image. The fourth display unit 4V is the surface on which this virtual image is displayed, and is located 2 m ahead of the driver D.

[0024] The fourth display 4 has multiple light sources 4L arranged in a grid pattern. The color and brightness of each light source 4L can be controlled as desired. The fourth display 4 emits light in a point-like pattern only in the areas corresponding to the emitting light sources 4L, and the design is formed by the emission of multiple points, making it possible to present virtual images of various designs to the driver D. The fourth display unit 4V is displayed in two locations, between the first display unit 1V and the third display unit 3V, and at the lower right and lower left of the first display unit 1V.

[0025] The fifth display 5 has a fifth display section 5V that displays fifth information 5a between the second display section 2V and the third display section 3V. Although not shown, the fifth display 5 is a well-known liquid crystal display that includes a light source consisting of a so-called three-color LED, a TFT (Thin Film Transistor) liquid crystal display panel that displays images, a circuit board that controls these, and a case that houses these.

[0026] The fifth display 5 is disposed below the left and right A-pillars C3. The fifth display unit 5V displays an image, which is viewed as a real image that is directly viewed by the driver D. The fifth display unit 5V is a liquid crystal display panel surface, and is located 1.2 m ahead of the driver D in the forward direction.

[0027] The sixth display 6 is a well-known instrument device (a so-called meter), and is disposed on the dashboard C2 behind the steering wheel C5 as seen by the driver D.

[0028] The seventh display 7 is a well-known car navigation system and is located on the dashboard C2 between the driver's seat and the passenger seat. The seventh display 7 identifies and displays the current location of the vehicle based on GPS signals and time information received by a GPS (Global Positioning System) receiver, and can also provide route guidance to the vehicle's destination based on the current location of the vehicle and map information stored in the device.

[0029] (Display method) When the vehicle start switch (for example, IGN (ignition) switch) is turned on, the information presentation device displays the vehicle speed (0 km / h at this point) as first information 1a on the first display unit 1V. At the same time, the third display unit 3V displays an opening bar graph as third information 3a by illuminating all light sources 3L in the preferred color set by the driver D.

[0030] When the vehicle starts to travel, the information presentation device displays the current vehicle speed (65 km / h at this point) as the first information 1a. Then, the information presentation device displays the fuel efficiency as the third information 3a on the third display unit 3V by changing the light color of the light source 3L according to the fuel efficiency state, which is the energy efficiency of the vehicle. For example, the fuel efficiency display emits green light when the fuel efficiency state is good, and emits white light when the fuel efficiency state is poor.

[0031] When the information presentation device detects an approaching vehicle behind the vehicle in the left lane, it displays an approach warning (triangle content in FIG. 2) as first information 1a on the first display unit 1V. Note that the detection of a rear vehicle or the like can be performed by using a number of well-known cameras, forward millimeter-wave radar, ultrasonic sensors, infrared sensors, etc., arranged inside and outside the vehicle to detect the positions and details of objects in the external environment of the vehicle, such as people, structures, and other vehicles.

[0032] Next, after a predetermined time (about one second), a design similar to the first information 1a (the triangular design in FIG. 2) is displayed as the fourth information 4a on the left fourth display section 4V.

[0033] Next, after a predetermined time, the third display unit 3V illuminates the area closest to the leftmost A-pillar C3 in the brightest color to display third information 3a to inform the driver D of the direction. The third information 3a is displayed in a gradation by lighting the leftmost light source 3L at the highest brightness and gradually decreasing the brightness toward the opposite A-pillar C3. At this time, the third display unit 3V illuminates with a width approximately equal to the design width of the fourth information 4a.

[0034] Next, after a predetermined time, the same content as the first information 1a (triangle content in FIG. 2) is displayed as the fifth information 5a on the left fifth display section 5V.

[0035] Next, after a predetermined time, the second display unit 2V on the left side displays the same content (triangle content in FIG. 2) as the first information 1a, the fourth information 4a, and the fifth information 5a as the second information 2a.

[0036] At this time, the information display devices (first information 1a, second information 2a, third information 3a, fourth information 4a, fifth information 5a) are all displayed in the same color, i.e., amber, to help the driver D recognize that the information is related. Also, as shown in FIG. 2, the information display devices are displayed in a straight line (approximately linear) as seen from the driver D in order to gradually guide the driver D's gaze, who is gazing ahead, to the side mirror C4, and are displayed in ascending order of furthest from the driver D in order to gradually change the driver D's focus (point of view) from far to near.

[0037] By forming the information display device in this manner, the information display device can attract the driver's D's attention from the front to the side mirror C4 while suppressing changes in the focus of the driver's eyes.

[0038] (Second embodiment) A second embodiment of an information presentation device according to the present disclosure will be described with reference to Figures 3 and 4. The same parts and equivalent portions as those in the first embodiment will be denoted by the same reference numerals.

[0039] In the first embodiment, an approaching vehicle is detected behind the vehicle in the left lane, and the information is sent from the first display 1 in front to the second display 2 on the left side. In this embodiment, an approaching vehicle is detected behind the vehicle in the right lane, and the information is sent from the first display 1 in front to the second display 2 on the right side (passenger side).

[0040] The first display 1 displays the first information 1a as in the first embodiment. The second display 2, the fourth display 4, and the fifth display 5 display the second information 2a, the fourth information 4a, and the fifth information 5a on the right side, respectively.

[0041] The third display 3 displays third information 3a to inform the driver D of the direction by illuminating the area closest to the rightmost A-pillar C3 in the brightest color. The third information 3a is displayed as a gradation in which the brightness of the light source 3L decreases toward the opposite A-pillar C3. At this time, the third display section 3V emits light with a width that fills (connects) the gap between the fourth display section 4V and the fifth display section 5V.

[0042] In this embodiment, the third display 3 performs sequential display as shown in Fig. 4. Sequential display means that the brightest part X of the third information 3a moves in a flowing manner from left to right in the order of Fig. 4(b), 4(c), 4(d), 4(e), and 4(a), and this movement is repeated.

[0043] In FIG. 4(a), the brightest portion X of the third marking 3a is located at the rightmost position of the third display portion 3V. In FIG. 4(b), the brightest portion X of the third marking 3a is located near the fourth display portion 4V. In FIG. 4(c), the brightest portion X of the third marking 3a is located slightly to the right of its position in FIG. 4(b). In FIG. 4(d), the brightest portion X of the third marking 3a is located slightly to the right of its position in FIG. 4(c). In FIG. 4(e), the brightest portion X of the third marking 3a is located slightly to the right of its position in FIG. 4(d).

[0044] By forming the information display device in this manner, the information display device can easily attract the driver's attention by displaying information from the first display 1 in front to the second display 2 on the passenger side, which is farther from the driver D.

[0045] (Third embodiment) A third embodiment of an information presentation device according to the present disclosure will be described with reference to Fig. 5. The same parts and equivalent portions as those in the second embodiment will be denoted by the same reference numerals.

[0046] In the second embodiment, information was directed from the first display 1 in front to the second display 2 on the right side (passenger seat side), but in this embodiment, information is directed from the first display 1 in front to the seventh display 7.

[0047] The first display 1 and the fourth display 4 display the first information 1a and the fourth information 4a in the same manner as in the second embodiment. In this embodiment, the second display and the fifth display 5 do not display anything.

[0048] The third display section 3V emits light with a width that fills (connects) the gap between the fourth display section 4V and the fifth display section 5V. The third display section 3V performs sequential display.

[0049] The seventh display unit 7 displays the same content as the first information 1a (triangle content in FIG. 5) on the display surface together with the message "Please be careful."

[0050] By forming the information display device in this manner, the information display device can attract the attention of the driver from the first display device 1 on the front to the seventh display device 7, and can also issue a warning.

[0051] (Variation) Although the information presentation device of the present invention has been described using the configuration of the above-mentioned embodiment as an example, the present invention is not limited to this, and it goes without saying that various improvements and design changes are possible in other configurations as long as they do not deviate from the gist of the present invention.

[0052] For example, the third display 3 may project and reflect display light emitted by the light-emitting unit onto a light-shielding portion C1b, which is a black light-shielding portion made of black ceramics formed around the windshield C1, to allow a virtual image to be viewed in front of the driver D. By forming it in this manner, the visibility of the third display unit 31 can be improved.

[0053] For example, the information presentation device may direct information from the first display 1 in front to the seventh display 7 via the sixth display 6.

[0054] For example, the second display unit 21 is a mirror surface disposed outside the vehicle, but may be a so-called electronic mirror disposed inside the vehicle that displays an image captured by a camera or the like.

[0055] For example, the information presentation device may detect not only vehicles approaching the vehicle but also pedestrians and the like around the vehicle and present the information to the driver D. In this case, the information presentation device displays images simulating a person's walking state as the first information 1a, the second information 2a, the fourth information 4a, and the fifth information 5a.

[0056] For example, if a vehicle detects a vehicle approaching from behind traveling in the same driving lane as the vehicle, the information presentation device may display first information 1a on the first display unit 1V, then display fourth information 4a on both left and right fourth display units 4V, then illuminate the third display unit 3V to fill the space between the left and right A-pillars C3, and then display fifth information 5a on both left and right fifth display units 5V.

[0057] For example, when the vehicle sets a destination on the seventh display 7, the information presentation device may present the driver D with a direction to turn when approaching an intersection. When the vehicle approaches 500 m before the intersection, the information presentation device may display an image of an arrow as first information 1a on the first display unit 1V, then display an image simulating an arrow as fourth information 4a on the fourth display unit 4V on the side of the direction of the turn, then light up the third display unit 3V over the width of the fourth display unit 4V on the side of the direction of the turn, and then display an image of an arrow as fifth information 5a on the fifth display unit 5V on the side of the direction of the turn.
