Summary of the Invention

Problems to be Solved by the Invention

[0004] When the main power supply of the vehicle is turned on, the startup videos (opening movies, splash screens) displayed on the plurality of display means are displayed individually for each display means. Therefore, variations are likely to occur in the display timing and display time, and due to the lack of uniformity in operation, it may give the passengers a cumbersome and rough impression. In addition, these startup videos are repeatedly displayed every time the passenger turns on the main power supply of the vehicle. Therefore, it is difficult to wipe out the negative impression that the passengers have on the display system, and it may reduce the user experience (an experience valuable to the user such as ease of use, appearance, and sense of satisfaction).

[0005] One of the objectives of the present invention is to provide a display system that was devised in view of the above problems and that gives a sense of unity to the operations of a plurality of displays and improves the user experience. Note that, not limited to this objective, any effects derived from each configuration shown in the "Mode for Carrying Out the Invention" described later and that cannot be obtained with conventional techniques are also regarded as other objectives of the present invention.

Mode for Carrying Out the Invention

[0015] [1. Configuration] FIG. 1 is a diagram showing the interior of a vehicle to which the display system according to the present invention is applied. On the front side of the vehicle interior, an instrument panel 3 (instrument panel) is provided, on which switches and meters for controlling the vehicle and various in-vehicle devices are arranged. The instrument panel 3 is provided, for example, in a range from the front of the driver's seat 4 to near the center in the vehicle width direction, or is provided over the entire dashboard over the entire vehicle width direction in the vehicle interior.

[0016] The instrument panel 3 is provided with a center display 1 and a meter display 2. Both the center display 1 and the meter display 2 are one of the display means for displaying various information as images (still images or moving images), and are, for example, a liquid crystal display, an organic EL display, a plasma display, a screen projector, or the like. The meter display 2 mainly displays information for the driver, and the center display 1 displays information for all passengers including the driver.

[0017] The display system according to the present invention is for displaying images on the center display 1 and the meter display 2. As accessory devices for each of the center display 1 and the meter display 2, a touch panel device for detecting a touch operation on the screen, an input device provided with a keyboard, physical buttons, or a touch pad, a line-of-sight detection device for detecting the line of sight, a gesture reading device for detecting a gesture operation, a speaker device for outputting sound or music, etc. may be provided.

[0018] The meter display 2 is arranged in front of the driver's seat 4 of the vehicle, and is provided, for example, in front of the steering wheel 5 or on the upper surface of the dashboard. In addition to a speedometer and a power meter (tachometer), a water temperature gauge, an oil temperature gauge, a motor temperature gauge, a battery temperature gauge, auxiliary machine information, road surface information, peripheral radar detection information, various warning icons, etc. can be displayed on the meter display 2. The meter display 2 is energized in a state where the vehicle can run (power on) and displays information related to the running of the vehicle. The meter display 2 shown in FIG. 1 is arranged at a position where the driver can view it through the gap above the steering wheel 5.

[0019] The center display 1 is disposed closer to the center in the vehicle width direction than the meter display 2, and is provided, for example, on the upper surface or the rear surface (the surface facing the passenger compartment) of the dashboard. In addition to information similar to that of the meter display 2, the center display 1 can display the current position information of the vehicle, map information, an image captured by an in-vehicle camera, Internet information, audio information, multimedia information, and the like. The center display 1 is energized and displays various information not only when the vehicle is in a drivable state but also when in-vehicle electrical components are in an operable state (accessory).

[0020] The vehicle shown in FIG. 1 is a left-hand drive vehicle, and the center display 1 is disposed on the right side of the meter display 2. When the vehicle is a right-hand drive vehicle, the center display 1 is disposed on the left side of the meter display 2. The position of the center display 1 in the vehicle width direction is not limited to only the center in the vehicle width direction, and can be disposed, for example, in front of the passenger seat. In addition, the position of the center display 1 in the height direction can be arbitrarily set, and may be at the same height as the meter display 2, or may be at a higher or lower position than the meter display 2.

[0021] FIG. 2 is a schematic block diagram of the display system according to the present invention. The display contents of the center display 1 and the meter display 2 are controlled by a display control device 10. The display control device 10 is a computer incorporating a processor (arithmetic processing unit) and a memory (storage device). The processing contents (programs) of the display control device 10 are stored in the memory, and the contents are executed by being appropriately read by the processor.

[0022] The display control device 10 may include a first control device that controls the center display 1 and a second control device that controls the meter display 2. In other words, the display control device 10 may be configured to be divided among a plurality of computers. Alternatively, the display control device 10 may simultaneously and parallelly control the center display 1 and the meter display 2. In other words, the display control device 10 may be a single computer that controls both the center display 1 and the meter display 2.

[0023] The main switch 11, the drive system ECU 12 (Electronic Control Unit), and the non-drive system ECU 13 are connected to the display control device 10 as information sources regarding the display content. Further, the center display 1 and the meter display 2 are connected to the display control device 10 as display means for displaying images. These information sources and display means are connected to the display control device 10 via an in-vehicle communication network or a dedicated signal line.

[0024] The main switch 11 is a switch for switching the state of the vehicle's main power supply. The state of the vehicle's main power supply can be switched among three types: on (ON), off (OFF), and accessory (ACC), according to, for example, the number of times the main switch 11 is pressed, the presence or absence of a wireless authentication key possessed by a regular occupant, the presence or absence of depressing the brake pedal, the operation position of the select lever, the operating state of in-vehicle electrical components, etc. Note that various known methods can be applied as specific methods for switching the vehicle's main power supply.

[0025] The drive system ECU 12 is a computer that controls drive-related devices for driving the vehicle. The drive system ECU 12 includes functions such as an engine ECU, a motor ECU, a battery ECU for motor drive, a brake ECU, a steering ECU, a suspension ECU, etc. Among the information transmitted from the drive system ECU 12, vehicle speed information and output information are displayed on the meter display 2. Other information can be displayed on the center display 1 or the meter display 2 according to the vehicle state and the selection of the occupants.

[0026] The non-drive system ECU 13 is a computer that controls devices other than drive-related devices. The non-drive system ECU 13 includes functions such as a door lock ECU, a light ECU, an in-vehicle camera ECU, a power window ECU, an air conditioner ECU, etc. The information transmitted from the non-drive system ECU 13 can be displayed on the center display 1 or the meter display 2 according to the vehicle state and the selection of the occupants.

[0027] A satellite positioning control device, a wireless communication control device, a multimedia control device, etc. (not shown) may be connected to the display control device 10. The satellite positioning control device is a car navigation control device that measures the position of the vehicle based on detection information such as GNSS (global navigation satellite system), a vehicle speed sensor, a steering angle sensor, a yaw rate sensor, etc. The wireless communication control device is an electronic control device that performs wireless communication with other computers via a wireless network.

[0028] The multimedia control device is an electronic control device that controls multimedia devices (radio, TV, physical media playback device, smartphone connection device, Internet distribution content playback device, etc.). The information transmitted from each of the satellite positioning control device, the wireless communication control device, and the multimedia control device can be displayed on the center display 1 or the meter display 2 according to the vehicle state and the selection of the occupants.

[0029] [2. Center startup video and first meter startup video] In the display system of this embodiment, when the main power supply of the vehicle is turned on, control is performed to display separate startup videos (opening movies) on the center display 1 and the meter display 2. The timing at which each startup video is played and the content to be played are set in advance or controlled by the display control device 10 so that a sense of unity is imparted to the operations of the displays 1 and 2.

[0030] 3(A) to 3(D) are diagrams showing, in order of display, frames included in a startup video displayed on the center display 1 and the meter display 2 when the main power supply of the vehicle is turned on. The center display 1 displays a center startup video 6 when the main power supply of the vehicle is turned on. Meanwhile, the meter display 2 displays a first meter startup video 7 at a timing according to the display content of the center startup video 6 displayed on the center display 1 when the main power supply of the vehicle is turned on. In other words, immediately after the main power supply is turned on, only the center startup video 6 starts to be played, and thereafter, the first meter startup video 7 starts to be played at an appropriate timing.

[0031] As shown in Fig. 3(A), immediately after the main power is turned on, nothing is displayed on the meter display 2, and a center startup video 6 is played on the center display 1. In the center startup video 6, a first line 21 is drawn extending in the left-right direction from the left-right center of the center display 1 to each of the left and right sides. The vertical position of the first line 21 is set to be near the vertical center of the center display 1.

[0032] 3(B), the first line 21 is preferably drawn so as to extend substantially horizontally. Moreover, the speed at which the left end of the first line 21 moves leftward is set to be the same as the speed at which the right end of the first line 21 moves rightward. The first line 21 is drawn so as to have a left-right symmetrical shape with respect to the median line C1 of the center display 1 (a perpendicular line passing through the center in the left-right direction when viewed from the front).

[0033] The movement of the first line 21 can be likened to a scene where, from the perspective of a bird flying towards the rising sun just before dawn, the sunlight gradually spreads left and right along the horizon or the horizontal line. The center startup video 6 is a video produced with the image of "sunrise" in mind and serves to remind the passengers who have turned on the main power of the vehicle of "the start of a new day". The first line 21 is preferably represented in a color with high brightness (e.g., white), and the background of the first line 21 is preferably represented in a color with low brightness (e.g., black).

[0034] Also, when the above scene is drawn in perspective, the objects existing on the ground (or the ripples on the sea surface) are considered to look like afterimages radially spreading downward from the vanishing point from the perspective of a bird flying at high speed. Therefore, as shown in FIG. 3(B), rays of light 23 (light streaks) radially spreading downward from the center portion in the left-right direction of the center display 1 may be drawn below the first line 21. Thereby, the sense of speed of the flying bird (that is, the sense of presence that the passengers sharing the perspective with the bird can simulate) is emphasized, and the passengers can be reminded of "a speedy start to a new day".

[0035] Thereafter, as shown in FIG. 3(C), the left end of the first line 21 reaches the left end side of the center display 1, and at the same time, the right end of the first line 21 reaches the right end side of the center display 1. Even after that, the first line 21 continues to be displayed for a while. Also, some of the plurality of rays of light 23 are drawn so as to gradually disappear, newly appear at another position, or slightly sway in the left-right direction.

[0036] When the first line 21 reaches each of the left and right side edges of the center display 1, the first meter startup video 7 is played on the meter display 2. In the first meter startup video 7, as shown in FIG. 3(D), a pair of second lines 22 extending from each of the left and right end sides of the meter display 2 towards the center portion in the left-right direction are drawn. The vertical position of the second line 22 is near the center portion in the vertical direction of the meter display 2.

[0037] Here, the time when the first line 21 reaches each of the left and right sides of the center display 1 is defined as a first time, and the time when the second line 22 starts to be drawn is defined as a second time. The second time is set to be at least a time later than the first time. Preferably, the second time is set so that the time lag from the first time to the second time is as small as possible (a predetermined time or less (for example, 1000 [ms] or less)). Alternatively, the second time is set so as to coincide with the first time.

[0038] 4(A) to 4(D) are diagrams showing, in display order, frames included in the startup moving image that are displayed on the center display 1 and the meter display 2 following the state of FIG. 3(D). 4(A), the pair of left and right second lines 22 are preferably drawn to extend substantially horizontally at substantially the same height. The speed at which the left end of the right-side second line 22 moves leftward is set to be the same as the speed at which the right end of the left-side second line 22 moves rightward. The second lines 22 are drawn to be symmetrical with respect to the median line C2 of the meter display 2 (a perpendicular line passing through the center in the left-right direction when viewed from the front).

[0039] Of the pair of left and right second lines 22, the second line 22 extending from the edge (the right edge in this embodiment) of the meter display 2 located closer to the center display 1 can be similar to the first line 21 extended beyond the center display 1 onto the meter display 2. The first meter startup video 7 is a video created with consideration for the continuity of the movements of the first line 21 and the second line 22, and serves to remind the occupant of the functional unity between the center display 1 and the meter display 2.

[0040] The second line 22 is preferably represented in a color with high lightness (e.g., white), and the background of the second line 22 is preferably represented in a color with low lightness (e.g., black). Also, the second line 22 is preferably represented in the same line drawing pattern as the first line 21. Here, the line drawing pattern refers to an attribute or a combination thereof that characterizes the impression of the appearance of a line, such as the color of the line, the thickness of the line, the transmittance, the line type (solid line, broken line, dotted line, chain line, etc.), the decoration of the line (patterns added around the path), and the type of brush (the shape of the pen tip, the brush pattern). By making the line drawing patterns of the first line 21 and the second line 22 the same, their sense of unity and coherence is emphasized.

[0041] In addition, similar to the rays 23 drawn below the first line 21 in the center display 1 of FIG. 4(A), rays 23 may be drawn below the second line 22 in the meter display 2. Preferably, the rays 23 in the meter display 2 are represented in the same line drawing pattern as the rays 23 in the center display 1. By making the line drawing patterns of the rays 23 the same, the sense of unity and coherence of the first line 21 and the second line 22 is further emphasized.

[0042] Thereafter, as shown in FIG. 4(B), a pair of left and right second lines 22 are connected together at the center in the left - right direction of the meter display 2. The first line 21 in the center startup video 6 continues to be displayed until the pair of second lines 22 in the first meter startup video 7 are connected at the center in the left - right direction. Thereby, the display contents of the center display 1 and the display contents of the meter display 2 become almost the same, and their sense of unity and coherence is emphasized.

[0043] As shown in FIGS. 4(C) and 4(D), after a pair of second lines 22 are connected in the first meter startup video 7, the first line 21 and the light rays 23 in the center startup video 6 gradually disappear (fade out). The first line 21 is drawn, for example, such that its color gradually approaches the background color and its line thickness gradually becomes thinner. When the first line 21 completely disappears, nothing is displayed on the center display 1, and the center startup video 6 ends. After the end of the center startup video 6, for example, a logo mark or a splash screen of a vehicle manufacturer or an electrical component manufacturer may be displayed, or a menu screen related to in-vehicle electrical components may be displayed.

[0044] On the other hand, the second line 22 in the first meter startup video 7 moves upward within the meter display 2 while deforming, and then continues to be displayed as a reference line for various types of information displayed on the meter display 2 even after the playback of the first meter startup video 7 ends. For example, the second line 22 and the light rays 23 shown in FIG. 4(C) are drawn so as to move upward while reducing their left-right dimensions toward the center in the left-right direction.

[0045] FIG. 4(D) is a diagram illustrating a case where the second line 22 remains as a reference line in the perspective view. The second line 22 and the light rays 23 are further deformed from the state shown in FIG. 4(C), and a perspective view simulating a state of looking down on the vehicle from above the rear of the vehicle is displayed.

[0046] In this perspective view, the second line 22 functions as a line representing the horizon drawn between the ground and the sky, and the light rays 23 function as a line representing the white line (lane boundary line) of the driving lane. In this way, by leaving the lines corresponding to the second line 22 and the light rays 23 even after the end of the first meter startup video 7, the unity of the design between the first meter startup video 7 and the normal use screen on the meter display 2 is enhanced.

[0047] FIG. 5(G) is a diagram illustrating a case where the second line 22 functions as a reference line for another piece of information. Here, the second line 22 continues to be displayed as a boundary line that demarcates the title of the character information and its content. For example, in a menu with the title "Various Settings", there are setting items such as "Display Type, Brightness, Character Size, Character Color", and the second line 22 functions as a horizontal boundary line that separates the title and the setting items. Note that the line corresponding to the flare 23 is omitted. By leaving the line corresponding to the second line 22 after the end of the first meter startup video 7 in this way, the sense of unity in the design between the first meter startup video 7 and the normal usage screen on the meter display 2 is enhanced.

[0048] [3. Second Meter Startup Video] In the display system of this embodiment, when the main power supply of the vehicle is turned on, the meter display 2 displays the second meter startup videos 8 and 9 after playing the first meter startup video 7. The second meter startup videos 8 and 9 include two types: the classic meter startup video 8 and the enhanced meter startup video 9 (enhanced meter startup video). The classic meter startup video 8 is a video that is played when the display mode of the meter display 2 shifts to the classic mode, and the enhanced meter startup video 9 is a video that is played when the display mode of the meter display 2 shifts to the enhanced mode (enhanced mode).

[0049] The classic mode is a mode in which the meters (for example, instruments such as a speedometer, a power meter, a tachometer, etc.) displayed on the meter display 2 become classic meters. A classic meter is a meter that converts the magnitude of a parameter (for example, running speed, output, engine speed, etc.) into the rotation angle from the reference position of the pointer and displays it. The left meter 28 (power meter) and the right meter 29 (speedometer) shown in FIG. 5(F) are specific examples of classic meters. A general classic meter is provided with a scale engraved in a circular or elliptical display area and a pointer that rotates to indicate the current value of the parameter.

[0050] The enhanced mode is a mode in which the meters displayed on the meter display 2 become enhanced meters (enhanced meters). An enhanced meter is a meter that converts the magnitude of a parameter into the rotation angle of a three-dimensional rotating body (for example, a cylinder, a circular column, a frustum of a cone, etc.) and displays a projection diagram, a projected view, etc. of the rotating body so that a cylindrical surface or a conical surface corresponding to the rotation angle can be seen. The left meter 38 (power meter) and the right meter 39 (speed meter) shown in FIG. 6(H) are specific examples of enhanced meters. A general enhanced meter is provided with a three-dimensional figure having an outer surface engraved with graduations and rotating about a rotation axis, and a pointer fixed so as to indicate the value of the current parameter.

[0051] [A. Classic Meter Startup Video] FIGS. 5(A) to (G) are diagrams for explaining the classic meter startup video 8 displayed on the meter display 2 following the state of FIG. 4(D). The two circles indicated by broken lines in FIG. 5(A) are virtual circles corresponding to the outlines of the circular left meter 28 and right meter 29 that are finally displayed as shown in FIGS. 5(F) and (G). Here, the virtual circle located on the left side is called the left circle, and the virtual circle located on the right side is called the right circle. The sizes of the left circle and the right circle are the same, and the centers of the left circle and the right circle are at the same height.

[0052] As shown in FIG. 5(A), the classic meter startup video 8 includes a left arc line 24 and a right arc line 25. The left arc line 24 is drawn so as to extend in an arc shape along the circumference upward and downward from the right end point of the left circle on the assumption that the above-mentioned left circle exists in the left part of the meter display 2. Thereafter, as shown in FIGS. 5(B) to (D), the left arc line 24 extends upward and downward tracing the circumference of the left circle and is drawn to be connected into one at the left end point of the left circle. The left arc line 24 is drawn at a position corresponding to the outline of the left meter 28.

[0053] Similarly, the right arc line 25 is a line drawn so as to extend in an arc shape along the circumference from the left end point of the right circle upward and downward, assuming that the above-mentioned right circle exists in the right part of the meter display 2. Then, as shown in FIGS. 5(B) to 5(D), the right arc line 25 extends vertically so as to trace the circumference of the right circle and is drawn to be connected at the right end point of the right circle. The right arc line 25 is drawn at a position corresponding to the contour of the right meter 29. The left arc line 24 and the right arc line 25 are drawn in a vertically symmetric shape with reference to the horizontal line H passing through the centers of the left circle and the right circle.

[0054] The movements of the left arc line 24 and the right arc line 25 can be likened to a scene where, for example, when observing the sunrise on the earth from a space station on the shadow side of the earth, sunlight spreads in an arc shape along the contour of the earth. Alternatively, it can be likened to a scene where sunlight spreads in an arc shape along the contour of the moon just before the end of a total solar eclipse (a scene where a diamond ring is formed). Although the motif of the classic meter startup video 8 (the second meter startup video) is "sunrise", it is intended to remind the passengers of "the beginning of a new day" as seen from a different perspective from the center startup video 6 and the first meter startup video 7.

[0055] The left arc line 24 and the right arc line 25 are preferably represented in a color with high brightness (for example, white), and preferably they are represented in the same line drawing style. More preferably, the left arc line 24 and the right arc line 25 are represented in the same line drawing style as the second line 22. Thereby, the sense of unity and integrity of the second line 22, the left arc line 24, and the right arc line 25 is emphasized.

[0056] Thereafter, as shown in FIGS. 5(E) to 5(G), the left arc line 24 is replaced with the contour line of the left meter 28, and the right arc line 25 is replaced with the contour line of the right meter 29. For example, the left arc line 24 and the right arc line 25 are drawn so as to gradually fade out, and the contour lines of the left meter 28 and the right meter 29 are drawn so as to gradually fade in. Also, the information displayed inside the left meter 28 and the right meter 29 is drawn so as to gradually fade in.

[0057] Specific examples of the information displayed inside the left meter 28 include an output meter and a battery level gauge 26. Specific examples of the information displayed inside the right meter 29 include a speed meter and a fuel level gauge 27. Note that the battery level gauge 26 and the fuel level gauge 27 are preferably displayed at a timing earlier in time than the output meter and the speed meter. The battery level gauge 26 and the fuel level gauge 27 may be displayed before the left arc line 24 and the right arc line 25 become a complete circle, or may be displayed after they become a complete circle.

[0058] For example, as shown in FIG. 5(E), when the left arc line 24 and the right arc line 25 are gradually fading out, the battery level gauge 26 is displayed inside the left arc line 24, and the fuel level gauge 27 is displayed inside the right arc line 25. Thereafter, when the contour lines of the left meter 28 and the right meter 29 are gradually fading in, the output meter and the speed meter are displayed. By preferentially displaying the battery level gauge 26 and the fuel level gauge 27, the remaining amount of energy, which is a prerequisite for driving the vehicle, can be immediately grasped by the occupant, improving convenience.

[0059] [B. Enhanced Meter Startup Video] Figures 6(A) to (H) are diagrams for explaining the enhanced meter startup video 9 that is displayed on the meter display 2 following the state of FIG. 4(D). The two circles (left circle and right circle) indicated by broken lines in FIG. 6(A) are virtual circles that deform into the contours of the bottom surfaces (outer surfaces) of the cylindrical left meter 38 and right meter 39 that are finally displayed, as shown in FIG. 6(H), and correspond to the left circle and right circle indicated by broken lines in FIG. 5(A).

[0060] As shown in FIG. 6(A), the enhanced meter startup video 9 includes a left arc line 24 and a right arc line 25. The movements of the left arc line 24 and the right arc line 25 in FIGS. 6(A) to (C) are substantially the same as the movements of the left arc line 24 and the right arc line 25 in FIGS. 5(A) to (C). Thereafter, as shown in FIG. 6(D), the left arc line 24 and the right arc line 25 are drawn so as to deform into an elliptical shape toward positions corresponding to the contours of the bottom surfaces of the left meter 38 and the right meter 39.

[0061] At this time, a left ray 30 that radially spreads rightward from around the left arc line 24 and a right ray 31 that radially spreads leftward from around the right arc line 25 may be drawn. Thereby, the three-dimensional effect of the cylinders corresponding to the left meter 38 and the right meter 39 is emphasized, and the production effect is enhanced such that the cylinders appear while rotating the bottom surfaces corresponding to the left arc line 24 and the right arc line 25.

[0062] Subsequently, as shown in FIG. 6(E), the left arc line 24 is gradually erased from its right end point, and the right arc line 25 is gradually erased from its left end point. The portion erased in the left arc line 24 spreads in an arc shape along the circumference upward and downward from the right end point of the left arc line 24. Similarly, the portion erased in the right arc line 25 spreads in an arc shape along the circumference upward and downward from the left end point of the right arc line 25.

[0063] As shown in Fig. 6(F), when the left arc line 24 is in a state of approximately the left semi-circle and the right arc line 25 is in a state of approximately the right semi-circle, the left elliptical line 32 and the right elliptical line 33 corresponding to the contours of the top surfaces (inner surfaces) of the left meter 38 and the right meter 39 are drawn. Also, a part of the left ray 30 becomes the contour of the cylindrical surface connecting the left arc line 24 and the left elliptical line 32, and a part of the right ray 31 becomes the contour of the cylindrical surface connecting the right arc line 25 and the right elliptical line 33. Thereby, as shown in Fig. 6(G), the left cylinder 34 corresponding to the left meter 38 and the right cylinder 35 corresponding to the right meter 39 are drawn.

[0064] Thereafter, as shown in Fig. 6(H), the contour line of the left cylinder 34 is replaced by the contour line of the left meter 38, and the contour line of the right cylinder 35 is replaced by the contour line of the right meter 39. For example, the contour lines of the left cylinder 34 and the right cylinder 35 are drawn so as to gradually fade out, and the contour lines of the left meter 38 and the right meter 39 are drawn so as to gradually fade in. Also, the information displayed inside the left meter 38 and the right meter 39 is also drawn so as to gradually fade in.

[0065] Specific examples of the information displayed inside the left meter 38 include the output meter, and specific examples of the information displayed inside the right meter 39 include the speed meter. Note that the battery remaining amount meter 36 and the fuel remaining amount meter 37 may be displayed inside the left meter 38 and the right meter 39, or may be displayed outside (for example, below) the left meter 38 and the right meter 39. Also, it is preferable that the battery remaining amount meter 36 and the fuel remaining amount meter 37 are displayed at a timing earlier in time than the output meter and the speed meter. The battery remaining amount meter 36 and the fuel remaining amount meter 37 may be displayed before the contour lines of the left meter 38 and the right meter 39 are displayed (when the left cylinder 34 and the right cylinder 35 are displayed), as shown in Fig. 6(G), or may be displayed after the contour lines of the left meter 38 and the right meter 39 are displayed.

[0066] [4. Video playback timing] The following table summarizes the playback timings of the videos displayed on the center display 1 and the meter display 2. For each of the startup videos 6 to 9 played on the center display 1 and the meter display 2, the length (total number of frames, total playback time) of each video may be preset so that the following playback timings are achieved. Also, the total playback speed (frame rate) of each video may be appropriately changed so that the following playback timings are achieved. Alternatively, the playback end timing may be appropriately adjusted by repeatedly playing (looping) or partially omitting (cutting) specific frames so that the following playback timings are achieved.

[0067]

Table 1

[0068] When the main power of the vehicle is turned on and the center display 1 is powered on, the center startup video 6 is immediately played on the center display 1. At this time, the meter display 2 is also powered on, but the first meter startup video 7 is not yet played. The meter display 2 can be regarded as being in a state of waiting for the progress of the center startup video 6. When the first line 21 of the center startup video 6 reaches both the left and right ends of the center display 1, the first meter startup video 7 is played on the meter display 2. During the playback of the first meter startup video 7, the playback of the center startup video 6 continues. The center display 1 can be regarded as being in a state of waiting for the progress of the first meter startup video 7.

[0069] Thereafter, the playback of the center startup video 6 and the first meter startup video 7 continues until the second line 22 of the first meter startup video 7 is connected into one. After the second line 22 is connected into one, the first line 21 of the center startup video 6 fades out, and the center startup video 6 ends. Also, the second line 22 of the first meter startup video 7 moves upward to a predetermined position, and the first meter startup video 7 ends. Note that the video while the first line 21 is fading out may not be included in the center startup video 6. Similarly, the video while the second line 22 is moving upward may not be included in the first meter startup video 7.

[0070] The second meter startup videos 8, 9 are played after the first meter startup video 7 on the meter display 2. When the display mode of the meter display 2 is the classic mode, the classic meter startup video 8 is played. When the display mode of the meter display 2 is the enhance mode, the enhance meter startup video 9 is played. These second meter startup videos 8, 9 may start playing while the second line 22 is moving upward, or may start playing after the movement of the second line 22 is completed.

[0071] [5. Effect] (1) The above display system displays images on the meter display 2 arranged in front of the driver's seat of the vehicle and the center display 1 arranged closer to the center in the vehicle width direction than the meter display 2. When the main power supply of the vehicle is turned on, the center display 1 displays the center startup video 6 in which the first line 21 extending in the left-right direction from the center portion in the left-right direction of the center display 1 toward each of the left and right sides is drawn. When the main power supply of the vehicle is turned on, after the first line 21 in the center startup video 6 reaches each of the left and right sides of the center display 1, the meter display 2 displays the first meter startup video 7 in which a pair of second lines 22 extending from each of the left and right ends of the meter display 2 toward the center portion in the left-right direction are drawn.

[0072] In this way, by associating the playback timing of the first meter startup video 7 with the movement of the first line 21 in the center startup video 6, a sense of unity can be given to the content and operations of the center startup video 6 and the first meter startup video 7. In particular, after the first line 21 reaches both the left and right sides of the center display 1, by extending the second line 22 from both the left and right ends of the meter display 2, the connection between the first line 21 and the second line 22 can be emphasized, creating an impression as if the extended tip of the first line 21 has become the second line 22. As a result, the operation of the display system when the main power of the vehicle is turned on can be felt as a series of smooth operations like a flowing motion, producing a refined impression, an elegant sense of luxury, and a stylish and sophisticated atmosphere. Therefore, the user experience can be improved.

[0073] Also, the first line 21 of the center startup video 6 can make the passengers associate with a scene where sunlight spreads horizontally to the left and right along the horizon or the horizontal line, reminding the passengers of "the beginning of a new day". Similarly, the second line 22 of the first meter startup video 7 can also make the passengers associate with the sunlight connected to the first line 21, reminding the passengers of "the beginning of a new day". Therefore, the concept of the center startup video 6 and the first meter startup video 7 can be strongly impressed on the passengers, and the user experience can be further improved.

[0074] Note that in a display system mounted on a vehicle, it is known that the startup process of the center display 1 takes a relatively short time, while the startup process of the meter display 2 may take a long time. For example, when the audio device and the multimedia device are not started at the time of turning on the main power supply, it is not necessary to reflect the states of these devices in the display content of the center display 1, and the processing load at startup is light. On the other hand, since various information necessary for driving the vehicle is displayed on the meter display 2, there are many items to be confirmed to be reflected in the display content, and the processing load at startup is heavy. Therefore, when trying to play the center startup video 6 and the first meter startup video 7 simultaneously, the start time of the playback of the first meter startup video 7 is delayed due to the delay in the startup process of the meter display 2, and accordingly, the start time of the playback of the center startup video 6 is also delayed. That is, the overall operation of the display system is delayed, giving the passengers a dull and shabby impression.

[0075] To address such problems, by playing the center startup video 6 on the center display 1 prior to the meter display 2 and then playing the first meter startup video 7 on the meter display 2 with a time margin, the response of the display system after turning on the main power supply can be improved, and a brisk and high-quality impression can be given to the passengers. Therefore, the user experience can be improved.

[0076] (2) In the above display system, the first line 21 in the center startup video 6 continues to be displayed until a pair of second lines 22 in the first meter startup video 7 are connected at the center in the left-right direction. Thereby, the connection between the first line 21 and the second line 22 can be strongly impressed, and an impression as if the extended tip of the first line 21 has become the second line 22 can be strongly created. Therefore, a refined and luxurious feeling can be produced, and the user experience can be improved.

[0077] (3) In the above display system, the meter display 2 is provided so as to be able to display information on the vehicle or in-vehicle device after the reproduction of the first meter startup video 7 ends. For example, as shown in FIG. 4(D), the meter display 2 is provided so as to be able to display a perspective view simulating a state of looking down on the vehicle from above the rear of the vehicle after the reproduction of the first meter startup video 7 ends. Alternatively, as shown in FIG. 5(G), the meter display 2 is provided so as to be able to display the title and content of character information. The second line 22 continues to be displayed after the reproduction of the first meter startup video 7 ends as a reference line for the above various types of information.

[0078] By making the second line 22 continue to be displayed as a reference line for various types of information in this way, the sense of unity and integrity in the design between the first meter startup video 7 and the subsequent normal use screen can be enhanced. Therefore, an elegant atmosphere can be effectively produced, and the user experience can be further improved. Also, with a reasonable design without waste, the functional beauty can be presented to the passengers, and the user experience can be further improved.

[0079] (4) In the above display system, the first line 21 and the second line 22 are expressed in the same drawing line style. For example, they are drawn as the same lines in terms of line color, line thickness, line type, line decoration, brush type, transmittance, etc. With such a configuration, the connection and unity between the first line 21 and the second line 22 can be further emphasized, and the user experience can be further improved.

[0080] (5) In the above display system, when the vehicle's main power supply is turned on, the meter display 2 plays the first meter startup video 7 and then displays the second meter startup videos 8 and 9. Further, the second meter startup videos 8 and 9 include a left arc line 24 and a right arc line 25. The left arc line 24 is a line that extends in an arc shape along the circumference from the right endpoint of the left circle upward and downward, assuming that virtual left and right circles exist in the left and right parts of the meter display 2, and is connected to the left endpoint of the left circle. Also, the right arc line 25 is a line that extends in an arc shape along the circumference from the left endpoint of the right circle upward and downward and is connected to the right endpoint of the right circle.

[0081] With such a configuration, it is possible to produce the connection between the left arc line 24 and the right arc line 25 corresponding to the left meters 28 and 38 and the right meters 29 and 39 displayed on the left and right parts of the meter display 2 and the second line 22. Also, the left arc line 24 and the right arc line 25 can remind the passenger of "the start of a new day" from a different perspective than the first line 21 of the center startup video 6 or the second line 22 of the first meter startup video 7. Therefore, the concept of the second meter startup videos 8 and 9 can be strongly impressed on the passenger, and the user experience can be further improved.

[0082] (6) In the above display system, the meter display 2 is provided so as to be able to display the circular left meter 28 and right meter 29 after the reproduction of the classic meter startup video 8 (second meter startup video) is completed. As shown in FIGS. 5(A) to 5(G), the left arc line 24 and the right arc line 25 are drawn at positions corresponding to the outlines of the left meter 28 and the right meter 29. By thus drawing the left arc line 24 and the right arc line 25 corresponding to the outlines of the left meter 28 and the right meter 29, the process in which the classic meter is displayed can be made to give a sophisticated impression, and the user experience can be further improved.

[0083] (7) In the above display system, the meter display 2 is provided so as to be able to display the cylindrical left meter 38 and right meter 39 after the playback of the enhanced meter start-up video 9 (second meter start-up video) is completed. As shown in FIGS. 6(A) to (H), the left arc line 24 and the right arc line 25 are drawn so as to deform into an elliptical shape toward the positions corresponding to the outlines of the bottom surfaces of the left meter 38 and the right meter 39. In this way, by drawing the left arc line 24 and the right arc line 25 corresponding to the outlines of the bottom surfaces of the left meter 38 and the right meter 39, the process of displaying the enhanced meter can be given a refined impression, and the user experience can be further improved.

[0084] (8) In the above display system, the second line 22, the left arc line 24, and the right arc line 25 are expressed in the same drawing line style. Thereby, the connection and the unity among the second line 22, the left arc line 24, and the right arc line 25 can be further emphasized, and the user experience can be further improved.

[0085] (9) In the above display system, the meter display 2 is provided so as to be able to display the speed meter, the output meter, the battery remaining amount gauges 26, 36, and the fuel remaining amount gauges 27, 37 after the playback of the first meter start-up video 7 is completed, and the battery remaining amount gauges 26, 36 and the fuel remaining amount gauges 27, 37 are displayed before the speed meter and the output meter.

[0086] For example, in the example shown in FIGS. 5(E) to (G), the left meter 28 is the output meter, and the right meter 29 is the speed meter. In the example shown in FIGS. 6(G) to (H), the left meter 38 is the output meter, and the right meter 39 is the speed meter. In any case, the battery remaining amount gauges 26, 36 and the fuel remaining amount gauges 27, 37 are displayed before the speed meter and the output meter. In this way, by preferentially displaying the battery remaining amount gauges 26, 36 and the fuel remaining amount gauges 27, 37, the remaining amount of energy, which is a prerequisite for driving the vehicle, can be immediately grasped by the occupant, and the convenience can be improved. Therefore, the user experience can be further improved.

[0087] [6. Others] The above embodiments are merely illustrative and are not intended to exclude various modifications and applications of technologies not explicitly stated in this embodiment. Each configuration of this embodiment can be implemented with various modifications without departing from their gist. In addition, each configuration of this embodiment can be selected as needed, or can be appropriately combined with various configurations included in the known technologies.

[0088] In the above embodiment, a display system is exemplified in which after the center startup video 6 and the first meter startup video 7 are played, second meter startup videos 8 and 9 such as the classic meter startup video 8 and the enhance startup video 9 are played. However, the playback of the second meter startup videos 8 and 9 can be omitted. At least when the main power supply of the vehicle is turned on, by displaying the center startup video 6 on the center display 1 and the first meter startup video 7 on the meter display 2, a sense of unity can be given to the operations of the plurality of displays 1 and 2, and the user experience can be improved.

[0089] In the above embodiment, the display control device 10 mounted on the vehicle displays the startup videos of the center display 1 and the meter display 2. However, it is also possible to adopt a device configuration in which a computer outside the vehicle displays the startup videos of the center display 1 and the meter display 2 via a network. Alternatively, it is also possible to configure the computers built into the center display 1 and the meter display 2 to display the startup videos respectively.

[0090] Note that the above display system is applicable to gasoline vehicles, hybrid vehicles, and plug-in hybrid vehicles (PHEVs) that can be externally charged or externally powered. A plug-in hybrid vehicle means a hybrid vehicle (Hybrid Electric Vehicle, HEV) equipped with an engine and a motor as drive sources, a generator as a power generation device, and a battery as a power storage device, and capable of external charging of the battery or external power supply from the battery.

[0091] The former plug-in hybrid vehicle is provided with a charging port (inlet) for inserting a charging cable through which power is supplied from external charging facilities, a non-contact power receiving device, and the like. The latter plug-in hybrid vehicle is provided with an external power supply outlet (outlet), a non-contact power supply device, and the like. It is also possible to install both the above-mentioned charging port and outlet on a single plug-in hybrid vehicle.
