The present invention relates to a vehicular display device.
Conventionally, a vehicular display device including a meter unit capable of displaying graphics such as a liquid crystal display panel is known. For example, in a display device disclosed in Patent Literature 1, when a user turns an ignition switch on to start an engine in order to start driving a vehicle, a display element is displayed vaguely in a central portion of a meter such as a speedometer, and then, a pointer of the meter is displayed. In this way, the user is prompted to look at the meter and the user experiences an innovative impression with varied display content.
Patent Literature 1: Japanese Unexamined Patent Publication No. 2014-157087
When an occupant starts driving a vehicle being parked, the occupant executes a getting-in action associated with getting into the vehicle such as unlocking of a door lock, opening of a door, or getting into a vehicle. In this case, the engine may not be started immediately after the getting-in action is executed. However, Patent Literature 1 makes no description relating to display until the engine is started after an occupant executes the getting-in action. Regarding the display, further improvement in displaying information until the engine is started after the occupant executes the getting-in action is required.
An object of the present invention is to provide a vehicular display device capable of displaying appropriate information until an engine is started after an occupant executes a getting-in action.
An aspect of the present invention is a vehicular display device mounted on a vehicle, including: a display panel that displays information relating to the vehicle; a display controller that displays an opening animation image in a predetermined display region of the display panel; and a detector that detects a getting-in action associated with an occupant getting in the vehicle, wherein the display controller displays a checklist indicating a checking result of a state of each unit of the vehicle in the predetermined display region as the information relating to the vehicle after a driving source for traveling of the vehicle is started, the display controller starts a display operation of displaying the opening animation image in the display region of the display panel when the getting-in action is detected by the detector, and continues the display operation at least until the checklist is displayed, and the display controller displays, as the opening animation image, an animation image, in which an image display operation of changing a display form of a graphic object is periodically repeated, on the display panel.
According to the present invention, the attention of the occupant can be attracted to the predetermined display region of the display panel when the occupant gets into the vehicle. Therefore, when the checklist is displayed on the predetermined display region of the display panel as the information relating to the vehicle, the occupant can better understand the checking result.
[Overall Configuration]
The display device 100 includes a display panel 200 and analog meters 300 and 500. The display panel 200 includes a display surface 210. The display panel 200 displays an image on the display surface 210. The display panel 200 may be a liquid crystal display that drives liquid crystals to display an image. Alternatively, the display panel 200 may be a plasma display which uses plasma emission. Further alternatively, the display panel 200 may be an organic electroluminescence (EL) display which uses an organic EL element. The principle of the present embodiment is not limited to a specific type of the display panel 200.
The image may contain information relating to a vehicle on which the display device 100 is mounted. As an example of the information relating to a vehicle, at least one of vehicle state information indicating the state of a vehicle, travel information relating to a traveling state of a vehicle, and environment information relating to an environment in which a vehicle travels can be employed. As an example of the state information, information indicating a residual fuel amount, the water temperature in a radiator, a lighting state of a headlight, and the like can be employed. As an example of the traveling information, a traveling speed of a vehicle, an engine speed, and the like can be employed. As an example of the environment information, a legal speed limit determined for a road on which a vehicle travels and information relating to the outside temperature or weather can be employed.
Similarly to analog meters mounted on existing vehicles, the analog meters 300 and 500 may provide information (for example, a vehicle speed, an engine speed, a water temperature in a radiator, and a residual fuel amount) relating to the vehicle on which the display device 100 is mounted to the driver.
The analog meter 300 is disposed on the left side of the display panel 200 and includes a C-shaped ring 310 and a pointing needle 320.
The pointing needle 320 rotates within a region surrounded by the C-shaped ring 310. Indexes (for example, scale marks and numbers) indicating physical amounts related to the traveling state of the vehicle on which the display device 100 is mounted are displayed in the region surrounded by the C-shaped ring 310. Presentation of indexes may follow various methods used in analog meters mounted on existing vehicles.
The analog meter 500 is disposed on the right side of the display panel 200, and similarly to the analog meter 300, provides information (for example, a vehicle speed, an engine speed, a water temperature in a radiator, and a residual fuel amount) indicating the traveling state of the vehicle on which the display device 100 is mounted to the driver, the information being different from that displayed in the analog meter 300.
The analog meter 500 includes a C-shaped ring 510 and pointing needles 520 and 530.
The pointing needles 520 and 530 rotate within a region surrounded by the C-shaped ring 510. In a region surrounded by the C-shaped ring 510, indexes (for example, scale marks and numbers) indicating the physical amounts related to the traveling state of the vehicle on which the display device 100 is mounted may be drawn on a display board 400.
The display device 100 further includes the display board 400. The display board 400 is disposed between the display panel 200 and the analog meters 300 and 500. The display board 400 includes a flat first surface 411 and a flat second surface 412. The first surface 411 faces the display panel 200. The analog meters 300 and 500 are attached to the second surface 412 on the opposite side of the first surface 411.
A display region 421 having a size and a shape approximately identical to those of the display surface 210 of the display panel 200 and a peripheral region 422 which is a region outside the display region 421 are provided in the display board 400.
The display region 421 may have optically higher transmittance than the peripheral region 422, for example. Video light emitted from the display surface 210 of the display panel 200 propagates from the first surface 411 to the second surface 412. After that, the video light is emitted from the display region 421 of the second surface 412.
The display device 100 further includes a ring-shaped member 600. The ring-shaped member 600 includes a ring member 610 and a translucent ring 620. The translucent ring 620 is disposed in the ring member 610. The translucent ring 620 contributes to giving a stereoscopic visual impression to the driver in cooperation with the ring member 610.
The display device 100 further includes a driving unit 700, a meter bezel 810, and a protective board 820. The pointing needle 320 of the analog meter 300 and the pointing needles 520 and 530 of the analog meter 500 are mechanically connected to the driving unit 700 with the display board 400 interposed.
The driving unit 700 rotates the pointing needles 320, 520, and 530. Various techniques used in the existing vehicles may be used for the connection between the driving unit 700 and the pointing needles 320, 520, and 530. Therefore, the principle of the present embodiment is not limited to a specific connection technique between the driving unit 700 and the pointing needles 320, 520, and 530.
The driving unit 700 may include a display controller 730 (see
The driving unit 700 may include driving motors 721, 722, and 723 (see
The meter bezel 810 is a cylinder that defines a space in which the display panel 200, the ring-shaped member 600, the analog meter 300, the analog meter 500, the display board 400, and the driving unit 700 are accommodated. The protective board 820 closes an opening of the meter bezel 810. The display panel 200, the ring-shaped member 600, the analog meters 300 and 500, and the display board 400 are disposed between the driving unit 700 and the protective board 820 in the meter bezel 810.
The protective board 820 is generally transparent. Therefore, video light generated by the display panel 200 can reach the protective board 820 through the display board 400, and after that, can enter the eyes of the driver. An optical treatment for suppressing reflection may be performed on the protective board 820. In this case, the driver visually perceives an image projected by the display panel 200 satisfactorily without being disturbed by the reflection on the protective board 820.
As illustrated in
Since the driver perceives that the analog meters 300 and 500 are attached to the second surface 412 to which an image is projected, the display device 100 can maintain visual integrity between the analog meters 300, 500 and the display panel 200.
[Screen Configuration]
The display surface 210 of the display panel 200 is disposed in a central portion of the display board region 410. The display surface 210 has a horizontally long rectangular shape. The ring-shaped member 600 is attached so that the center thereof is positioned at the center of the display surface 210, for example.
The display surface 210 displays a meter image SCI (an example of the ring-type analog meter) in the ring-shaped member 600. In the example of
The meter image SCI is displayed on the display surface 210 so as to fit into the translucent ring 620 and includes an index image 211 and a pointing needle image 212. The index image 211 includes a plurality of scale marks which are disposed at an equal interval in a radial form so as to indicate the traveling speed. In the example of
In the example of
The analog meter 300 is disposed on the left side of the display surface 210, and the analog meter 500 is disposed on the right side of the display surface 210.
The analog meter 300 includes the C-shaped ring 310 having a circular arc shape that defines an outer edge of the analog meter 300, and the analog meter 500 includes the C-shaped ring 510 having a circular arc shape that defines an outer edge of the analog meter 500. The C-shaped rings 310 and 510 have the same size and shape, and are disposed at an equal distance in a horizontal direction from the center of the ring member 610. Moreover, the C-shaped ring 310 is disposed so that an upper end 311 and a lower end 312 face the ring member 610, and the C-shaped ring 510 is disposed so that an upper end 511 and a lower end 512 face the ring member 610. In this way, the analog meters 300 and 500 are disposed linearly symmetrical about the center of the ring member 610.
The analog meter 300 has an index portion 313 disposed along an inner circumference of the C-shaped ring 310. The index portion 313 includes a plurality of scale marks disposed radially along the inner circumference of the C-shaped ring 310 and numbers corresponding to the scale marks. In
The pointing needle 320 is configured as a needle-shaped member that rotates about the center of the analog meter 300 and extends linearly in the radial direction of the C-shaped ring 310. The pointing needle 320 rotates in the range between the scale mark of the number “0” and the scale mark of the number “9”.
The analog meter 500 includes two meters which are disposed on the upper and lower sides and which share the C-shaped ring 510. In the example of
The analog meter 500 includes an index portion 513a of a fuel meter and an index portion 513b of a temperature meter disposed along the inner circumference of the C-shaped ring 510. The index portion 513a includes a plurality of scale marks disposed radially at an equal interval along the inner circumference of the lower half portion of the C-shaped ring 510. The index portion 513b includes a plurality of scale marks disposed radially at an equal interval along the inner circumference of the upper half portion of the C-shaped ring 510. The index portion 513b has a scale mark indicating the lowest temperature disposed slightly above the center in the vertical direction of the C-shaped ring 510 and a scale mark indicating the highest temperature disposed close to the upper end 511. Moreover, the index portion 513a has a scale mark indicating the full state of fuel disposed slightly below the center in the vertical direction of the C-shaped ring 510 and a scale mark indicating the empty state of fuel disposed close to the lower end 512.
In the analog meter 500, an indicator IN indicating that the upper meter is a temperature meter is disposed on the right side of the pointing needle 530, and an indicator IN indicating that the lower meter is a fuel meter is disposed on the right side of the pointing needle 520.
The pointing needle 520 is configured as a needle-shaped member that rotates about a side slightly below the center of the analog meter 300 and extends linearly in the radial direction of the C-shaped ring 510. The pointing needle 520 rotates in the range between a scale mark indicating the empty state of fuel and a scale mark indicating the full state of fuel.
The pointing needle 530 is configured as a needle-shaped member that rotates about a side slightly above the center of the analog meter 300 and extends linearly in the radial direction of the C-shaped ring 510. The pointing needle 530 rotates in the range between a scale mark indicating a lowest temperature and a scale mark indicating a highest temperature.
The C-shaped ring 310 has a circular arc shape that is larger than a semi-circle and runs around a bottom-left corner C1 of the display surface 210. The upper end 311 of the C-shaped ring 310 enters into the display surface 210 from the left edge H2 of the display surface 210, so that the C-shaped ring 310 is disposed close to the left edge 112. The lower end 312 of the C-shaped ring 310 comes into contact with the lower edge H1 of the display surface 210, so that the C-shaped ring 310 is disposed close to the lower edge H1.
The C-shaped ring 510 has a circular arc shape that is larger than a semi-circle and runs around a bottom-right corner C2 of the display surface 210. The upper end 511 of the C-shaped ring 510 enters into the display surface 210 from the right edge H4 of the display surface 210, so that the C-shaped ring 510 is disposed close to the right edge H4. The lower end 512 of the C-shaped ring 510 comes into contact with the lower edge H1 of the display surface 210, so that the C-shaped ring 510 is disposed close to the lower edge H1.
That is, the C-shaped rings 310 and 510 run around toward the lower edge H1 from the lower side of the display surface 210. In this way, it is possible to secure the region of the analog meters 300 and 500 without increasing the horizontal width of the display device 100.
The index portions 313 and 513a are disposed along the inner circumferences of the C-shaped rings 310 and 510 so as to run around the corners C1 and C2, respectively. Specifically, the index portion 313 extends to a run-around region 315 which extends from a lowermost portion 314 of the C-shaped ring 310 to the lower end 312 of the C-shaped ring 310. Moreover, the index portion 513a extends to a run-around region 515 which extends from a lowermost portion 514 of the C-shaped ring 510 to the lower end 512 of the C-shaped ring 310. In this way, it is possible to increase the region of the index portions 313, 513a, and to secure a sufficiently large interval between scale marks.
An upper edge H3 of the display surface 210 is positioned above uppermost portions 316 and 516 of the C-shaped rings 310 and 510. Moreover, the ring-shaped member 600 has a larger diameter than the C-shaped rings 310 and 510, and a lowermost portion 610a is positioned below the lower edge H1 of the display surface 210. Due to this, it is possible to secure a sufficiently larger region of the ring-shaped member and to improve the visibility of the meter image SCI displayed on the inner side of the ring-shaped member 600.
Furthermore, the lowermost portions 314 and 514 of the C-shaped rings 310 and 510 and the lowermost portion 610a of the ring-shaped member 600 are at the same height position. In this way, the lower ends of the analog meters 300 and 500 and the ring-shaped member 600 are uniform, and the aesthetic impression of the entire display device 100 can be enhanced.
In the display surface 210, display regions 213 and 214 capable of displaying images are set in regions on the outer sides of the ring-shaped member 600. The display region 213 is disposed on the left side of the ring-shaped member 600 and the display region 214 is disposed on the right side of the ring-shaped member 600.
The ECU 750 controls the operation of each unit of the vehicle. The ECU 750 includes the driving unit 700. The ECU 750 may include a microcomputer and a memory. The ECU 750 may include a program stored in the memory. Although the ECU 750 illustrated in
The driving unit 700 includes a first driving signal generator 711, a second driving signal generator 712, a third driving signal generator 713, the first driving motor 721, the second driving motor 722, the third driving motor 723, a display controller 730, an image memory 731, and a lighting controller 740.
The first driving signal generator 711 is electrically connected to the first driving motor 721. The first driving motor 721 is mechanically connected to the pointing needle 320. The second driving signal generator 712 is electrically connected to the second driving motor 722. The second driving motor 722 is mechanically connected to the pointing needle 520. The third driving signal generator 713 is electrically connected to the third driving motor 723. The third driving motor 723 is mechanically connected to the pointing needle 530. The display controller 730 is electrically connected to the display panel 200. The lighting controller 740 is electrically connected to the indicator IN.
Various sensor devices (not illustrated) that detect physical amounts which change according to the traveling state of the vehicle are disposed in the vehicle. A sensor group SSG includes these sensor devices. The sensor group SSG generates various detection signals indicating various physical amounts. In the example of
In the present embodiment, the sensor group SSG includes a lock sensor 761, a door sensor 762, and a seat sensor 763. The lock sensor 761 detects unlock and lock of a door lock of the vehicle. The door sensor 762 detects opening and closing of doors of the vehicle. The seat sensor 763 detects the occupant getting in the vehicle (specifically, the occupant sitting on a seat of the vehicle). The sensors including the lock sensor 761, the door sensor 762, and the seat sensor 763 that constitute the sensor group SSG may be sensors used in existing vehicles. Therefore, the principle of the present embodiment is not limited to the specific sensor of the sensor group SSG.
The first driving signal generator 711 receives a detection signal indicating a physical amount (in the present embodiment, an engine speed) corresponding to an index indicated by the pointing needle 320. The first driving signal generator 711 generates a driving signal according to the detection signal. The driving signal is output from the first driving signal generator 711 to the first driving motor 721. The first driving motor 721 rotates according to the driving signal. As a result, the pointing needle 320 can rotate on the display board 400.
The second driving signal generator 712 receives a detection signal indicating a physical amount (in the present embodiment, a residual fuel amount) corresponding to an index indicated by the pointing needle 520. The second driving signal generator 712 generates a driving signal according to the detection signal. The driving signal is output from the second driving signal generator 712 to the second driving motor 722. The second driving motor 722 rotates according to the driving signal. As a result, the pointing needle 520 can rotate on the display board 400.
The third driving signal generator 713 receives a detection signal indicating a physical amount (in the present embodiment, the water temperature in the radiator) corresponding to an index indicated by the pointing needle 530. The third driving signal generator 713 generates a driving signal according to the detection signal. The driving signal is output from the third driving signal generator 713 to the third driving motor 723. The third driving motor 723 rotates according to the driving signal. As a result, the pointing needle 530 can rotate on the display board 400.
Conversion from a detection signal to a driving signal may follow various signal processing techniques used in existing analog meters. Therefore, the principle of the present embodiment is not limited to a specific signal processing technique for converting a detection signal to a driving signal.
The display controller 730 receives a detection signal indicating a physical amount (in the present embodiment, a traveling speed of the vehicle) corresponding to the meter image SCI (see
A signal processing technique for displaying images from a detection signal may follow various existing image generation techniques. Therefore, the principle of the present embodiment is not limited to a specific signal processing technique for displaying images.
An engine 751, a starter 752, and an ignition switch 753 are further mounted on the vehicle. The engine 751 is an existing driving source for causing the vehicle to travel. The starter 752 is an existing motor for starting the engine 751. The ignition switch 753 is an existing operation unit for starting the engine 751. When the ignition switch 753 is turned on, the ECU 750 supplies electric power to the starter 752. The starter 752 to which electric power is supplied starts the engine 751.
The ignition switch 753 may be a lever, a button, or a dial provided near a driver's seat. The principle of the present embodiment is not limited to a specific structure of the ignition switch 753. The driving source that causes the vehicle to travel is not limited to the engine 751. For example, when the vehicle is an electric vehicle, a motor provided instead of the engine 751 is a driving source, and the starter 752 is not required.
The lighting controller 740 turns the indicator IN on or off according to the detection signal output from the sensor group SSG. When unlock of the door lock is detected by the lock sensor 761 in a state in which the engine 751 is stopped, the ECU 750 starts checking the status of each unit of the vehicle. As for the status of hydraulic pressure or the like which needs to be checked after an operation of a driving source such as the engine 751 starts, the ECU 750 determines a detection signal output from the sensor group SSG and checks the status after the operation of the driving source such as the engine 751 starts.
When opening of the door is detected by the door sensor 762 subsequently to unlock of the door lock, the display controller 730 starts an operation of displaying an opening animation image on the display panel 200. Alternatively, the display controller 730 may start displaying the opening animation image on the display panel 200 when sitting of the occupant is detected by the seat sensor 763 subsequently to opening of the door. Further alternatively, the display controller 730 may start displaying the opening animation image on the display panel 200 when unlock of the door lock is detected by the lock sensor 761. The opening animation image will be described with reference to
The display controller 730 displays the graphic object 771 at the center of a region of the display surface 210 facing the ring member 610. First, as illustrated in Section (A) of
As illustrated in Section (B) of
The display controller 730 displays the wavy graphic object 772a on the left side of the graphic object 771 and displays the wavy graphic object 772b on the right side of the graphic object 771. The graphic objects 772a and 772b are displayed bilaterally symmetric with respect to a vertical line that passes through the center of the display surface 210. In this example, although the graphic objects are described to be horizontally symmetrical, the graphic objects may not necessarily be horizontally symmetrical as long as the objects represent an image which spreads horizontally symmetrical from the central portion.

Subsequently, as illustrated in Section (B) of
The display controller 730 moves the left graphic object 772a further toward the left side until the left end thereof comes into contact with the left end of the display surface 210. Moreover, the display controller 730 moves the right graphic object 772b further toward the right side until the right end thereof comes into contact with the right end of the display surface 210. The display controller 730 removes the graphic objects 772a and 772b in a state illustrated in Section (C) of
In the present embodiment, the display controller 730 repeatedly displays the images of Sections (A), (B), and (C) at a cycle (for example, approximately 1 second) close to the heartbeat of a human. As a result, such a dramatic presentation as the beating of the heart of a vehicle is given.

When the checking result of all statuses is displayed, after the elapse of a predetermined period (in the present embodiment, 1 second for example), the display controller 730 displays the meter image SCI described using
As described above, in the present embodiment, checking of the status of the vehicle starts when the door lock is unlocked, and the displaying of the opening animation image 770 starts when the door is opened. Moreover, when the engine 751 is started, the status checklist 773 is displayed. Therefore, according to the present embodiment, it is possible to attract the eyes of the occupant toward the display panel 200 from the time point at which the occupant gets into the vehicle. In this way, it is possible to cause the occupant to look at the status checklist of the vehicle. As a result, it is possible to enhance the understanding of the occupant on the vehicle status.
According to the present embodiment, by displaying the opening animation image 770 on the display panel 200, it is possible to elevate feeling such as expectation or pleasure of the occupant when starting driving.
According to the present embodiment, the display controller 730 removes the graphic object 771 in a state illustrated in Section (C) of
[Modification]

The display controller 730 may display a vehicle state including another item of information relating to the vehicle, for example, on the display panel 200.
The ECU 750 may store a travel distance per trip in an internal memory whenever the vehicle makes a trip. The ECU 750 may calculate a mileage from the travel distance and a decrease in the residual fuel amount whenever the vehicle makes a trip, and may store the calculated mileage in the internal memory. The ECU 750 may calculate the travelable distance when fuel is not supplied from the residual fuel amount and the previous mileage. The sensor group SSG may include a temperature sensor that detects the outside temperature.
When the ignition switch 753 is operated and the engine 751 is started by the starter 752, the ECU 750 may notify the calculated travelable distance, the previous mileage and the previous travel distance stored in the memory, and the outside temperature detected by the temperature sensor to the display controller 730.
