This application is a U.S. National Phase Application under 35 U.S.C. 371 of International Application No. PCT/JP2013/007522 filed on Dec. 23, 2013 and published in Japanese as WO 2014/112016 A1 on Jul. 24, 2014. This application is based on and claims the benefit of priority from Japanese Patent Application No. 2013-004526 filed on Jan. 15, 2013. The entire disclosures of all of the above applications are incorporated herein by reference.
TECHNICAL FIELD
The present disclosure relates to a vehicle operating system including an operating device, and also relates to an information device. The operating device is disposed in a compartment of a vehicle and a position of the operating device in the compartment of the vehicle is changeable by a user. The information device is capable of being carried into the compartment of the vehicle and being used in the compartment of the vehicle.
BACKGROUND ART
As a multifunctional operating switch system mounted to a vehicle, a system usually includes a display device displaying operation states of in-vehicle devices including meters, an air conditioner, an audio device, and a car navigation device, and also includes a multifunctional switch (operating device) used for operating the in-vehicle devices (refer to, for example, patent literature 1). The multifunctional switch includes a round-shaped operating button. Instructions for hierarchical selecting, determining, and executing of items displayed on the screen of the display device can be performed by manipulating or pressing (tilting) any of the up, down, left, and right part of the perimeter of the operating button, or pushing the center of the operating button. Herein, the volume of the audio device can be adjusted irrespective of the hierarchy by manipulating or rotating the operating button.
The above multifunctional switch is attached in fixed manner to, for example, a central portion of an instrument panel (cluster lid C) in the vicinity of a driver seat. No consideration has been taken into for free movement of the multifunctional switch. There are users' needs for attaching the operating device to a top portion of a dashboard, to a portion between a user seat and a passenger seat, to a side portion of a door, to a side portion or to a top portion of a steering wheel, to a side portion or to a top portion of a steering column, to a ceiling, to a rear seat, or to any other place except for the central portion of the instrument panel.
In this case, assuming that the operating device is able to freely attachable and detachable, and is able to connect to an in-vehicle device (display device) in wireless manner (or in wired manner) in order to configure a system, the users' needs for freely disposing the operating device in an arbitrary place can be satisfied. However, the manipulating direction of the operating device and the arrangement direction in which items are aligned on a screen of the display device (cursor moving direction) may be different from each other. This inconsistency may cause the user to feel uncomfortable during the manipulation, and may degrade a manipulation performance of the operating device.
In recent years, a user often carries his or her information device, for example, a smartphone, a portable navigation device, or a tablet type personal computer into a compartment of the vehicle and sets the information device on an instrument panel for use, and operates the information device. In this case, if the operating device can be used to operate the information device carried by the user, the operating device may further improve user experience.

EMBODIMENTS FOR CARRYING OUT INVENTION
First Embodiment
The following will describe a first embodiment of the present disclosure with reference to FIG. 1 to FIG. 5B. FIG. 1 schematically shows an arrangement in a compartment 1 of a vehicle (passenger car) in the vicinity of a driver seat. Herein, an instrument panel 2 is located on the front side of the driver seat. A meter unit 3 is included in the instrument panel 2 in an embedded manner. A steering wheel 5 supported by a steering column 4 is disposed in front of the meter unit 3. That is, the steering wheel 5 is closer to the driver seat compared with the meter unit 3. The meter unit 3 includes a speedometer, tachometer, fuel meter, water temperature gauge, and various warning lamps, though they are not shown.
A vehicle operating system 6 according to the present embodiment includes a display device 7 that is embedded at a central portion 2a of the instrument panel 2. The display device 7 is provided by, for example, a color liquid crystal display. The display device 7 displays various screen images including a map screen image and a screen image for controlling (instructing or selecting) each in-vehicle device. In the vicinity of the display device 7, an operating switch unit (OP SW) 8 including multiple mechanical switches is disposed. A shift lever 10 is located at a center console 9 between the driver seat and a front passenger seat.
The vehicle operating system 6 according to the present embodiment includes, as shown in FIG. 2, the display device (DISPLAY) 7, an in-vehicle device (IN-V DEVICE) 25, and a unitized operating device (OP APPA) 12. The display device 7 includes a central processing unit (CPU) 11 that controls a display on the display device 7. The operating device 12 is disposed so that a user can perform a selection operation on a graphical user interface (GUI) displayed on the screen of the display device 7. The operating device 12 enables an instruction input, a selection, or a setting of each in-vehicle device. The graphical user interface is referred to as graphics for simplification.
As shown in FIG. 1, the operating device 12 includes, for example, a disk-shaped base 13 and a cylindrical rotatable knob 14 disposed on the disk-shaped base 13. The knob 14 is rotatable and pressable, and can be manipulated both in rotation manner and in push or pressing manner. The operating device 12 (base 13) can be freely attached, in any posture, to a portion inside the compartment 1 of the vehicle according to a personal predilection of the user in a detachable manner.
More particularly, for example, the operating device 12 can be attached to (the position to which the operating device is attached can be varied among) a position below the display device 7 at the central portion 2a of the instrument panel 2, an upper surface of the center console 9 (behind the shift lever 10), an upper surface of the steering column 4, a left side surface or a right side surface of the steering column 4, an upper surface (spoke surface) of the steering wheel 5, an internal surface of the door adjacent to the driver seat or an internal surface of the door adjacent to the front passenger seat, a surface of the ceiling, a position in the vicinity of a rear seat, or any other position that conforms to the personal predilection of the user. The present embodiment does not specifically limit a method of attaching the operating device 12 to any one of above-described parts of the compartment 1. For example, the operating device 12 may be attached to a position by screwing, mechanical engagement, attraction using a magnet, or adhesion using a double-sided tape.
As in FIG. 2, the operating device 12 includes a CPU 15 that controls the entire device, a rotation detector (ROT DETC) 16 that detects a rotation amount (including a rotation direction) of the rotatable knob 14, and a determination switch (DT SW) 17 that is turned on when the rotatable knob 14 is pressed. For example, the rotation detector may be provided by a rotary encoder. The rotation detector 16 and the determination switch 17 generate detection signals, and output the detection signals to the CPU 15.
The operating device 12 further includes a posture detection sensor (POSTURE DETC) 18 that detects an attachment posture of the operating device 12. The posture detection sensor 18 functions as a posture detector. The posture detection sensor 18 includes one or more sensors such as a gyro sensor, a tilt sensor, and an acceleration sensor. The posture detection sensor 18 detects, as the attachment posture of the operating device 12, an orientation direction of the rotatable knob 14 (direction in which a rotating axial center extends) with reference to a traveling direction of a vehicle. The posture detection sensor 18 generates a detection signal, and outputs the detection signal to the CPU 15.
The operating device 12 further includes a communication unit (COMM) 19 connected to the CPU 15. In the present embodiment, the communication unit 19 is provided by a near field communication unit (wireless communication unit) conformable to, for example, Wi-Fi (registered trademark) or Bluetooth (registered trademark). The communication unit 19 functions as a connection unit that connects the CPU 15 of the operating device 12 to the CPU 11 of the in-vehicle device 25 by communicating with a communication unit (COMM) 24 connected to the CPU 11. The operating device 12 has a built-in battery (BATTERY) 20 which serves as a power supply.
FIG. 2 schematically shows the electrical configuration of the vehicle operating system 6 (CPU 11) according to the present embodiment and peripheral components of the vehicle operating system 6. The display device 7 and the operating switch unit 8 are connected to the CPU 11. The CPU 11 is connected to the navigation device (NAVI) 21 and audio device (AUDIO) 22 that configure a part of the in-vehicle devices. As already known, the navigation device 21 performs navigation processing. As the navigation processing, the navigation device 21, for example, detects a position of the vehicle using a GPS, or performs a route guidance. The audio device 22 is able to receive radio signals or television signals, or is able to reproduce a music CD or picture DVD.
The CPU 11 is connected to other in-vehicle devices (OTHER DEVICE) 23 (or ECUs that control the in-vehicle devices) over an onboard network, for example, CAN. The onboard network are not shown in the drawing particularly. The CPU 11 is connected to the communication unit 24 that serves as a connection unit (which performs wireless communication). The communication unit 24 connects the operating device 12 (communication unit 19) with the CPU 11. The communication unit is provided by a near field communication unit conformable to, for example, Wi-Fi or Bluetooth (registered trademark).
The operating device 12 (CPU 15) outputs a detection signal (rotation manipulation signal) of the rotation detector 16, which is generated by a rotation manipulation performed to the rotatable knob 14, and a turning-on signal (determination signal) of the determination switch 17, which is generated by a pressing manipulation performed to the rotatable knob 14. The operating device 12 transmits the detection signal and the turning-on signal to the CPU 11 of the in-vehicle device 25 via the communication unit 19. In addition, the operating device 12 (CPU 15) transmits an attachment posture signal, which is produced by the posture detection sensor 18, to the CPU 11 via the communication unit 19. Therefore, the CPU 15 functions as a manipulation signal output unit and posture signal output unit.
When the CPU 11 of the vehicle operating system 6 receives (inputted with) the signals transmitted from the operating device 12 via the communication unit 24, the CPU 11 performs necessary display on the screen of the display device 7, performs display processing related to selection manipulation according to the rotation manipulation signal, and performs determination processing on the basis of the determination signal. In this case, the CPU 11 uses the software configuration to display, for example, icons as a graphical user interface (GUI) on the screen of the display device 7 so as to prompt a user to perform a selection manipulation to any one of the icons. The CPU 11 may also use the software configuration to display an indicator as the graphical user interface so as to prompt the user to change an indicator needle.
At this time, the CPU 11 displays the graphical user interface (GUI) on the display device 7 in a form corresponding to the attachment posture signal. More particularly, as described later in relation to the operation of the invention, in the present embodiment, an arrangement direction of icons on the screen of the display device 7 (including a position on the screen at which the icons are located) is changed from one direction to another direction, or the orientation of the indicator is changed from one direction to another direction. The CPU 11 therefore functions as a display control unit and selection display unit.
The following will describe an operation of the vehicle operating system 6 having the foregoing configuration with reference to FIG. 3 to FIG. 5B. The flowchart of FIG. 3 describes an outline of a processing procedure that is executed by the CPU 11. Herein, the processing is related to a display mode of a graphical user interface on the screen of the display device 7 when an attachment posture signal is transmitted from the operating device 12. FIG. 4A to FIG. 5B show concrete examples of display on the screen of the display device 7. FIG. 4A and FIG. 4B show an example of display of, for example, a menu selection screen image of the navigation device 21. FIG. 5A and FIG. 5B show an example of display of an audio volume setting screen image of the audio device 22.
It is noted that a flowchart or the processing of the flowchart in the present disclosure includes sections (also referred to as steps), each of which is represented, for instance, as S1. Further, each section can be divided into several sub-sections while several sections can be combined into a single section. Furthermore, each of thus configured sections can be also referred to as a circuit, device, module, or means.
As mentioned above, the operating device 12 can be attached to a position that conforms to the personal predilection of the user in the vehicle component 1. For example, when the operating device 12 (base 13) is attached to the top surface of the center console 9, the attachment posture of the operating device is almost in horizontal placement (the axial center of the rotatable knob 14 is oriented upward). When the operating device 12 is attached to the ceiling of the component 1, the attachment posture of the operating device is almost in horizontal placement (the axial center of the rotatable knob 14 is oriented downward). When the operating device 12 (base 13) is attached to the instrument panel central portion 2a or the spoke of the steering wheel 5, the attachment posture is in fore-and-aft orientation (the axial center of the rotatable knob 14 is oriented forward). When the operating device 12 (base 13) is attached to the left side surface or the right side surface of the steering column 4 or the internal surface of the door, the attachment posture is in lateral orientation (the axial center of the rotatable knob 14 is oriented leftward or rightward).
In the flowchart of FIG. 3, when the CPU 11 receives an attachment posture signal from the operating device 12, the CPU 11 decides at S1 whether the attachment posture of the operating device 12 is in horizontal placement. When the CPU 11 decides that the attachment posture of the operating device 12 is in horizontal placement (S1: YES), the CPU 11 decides at S2 whether the operating device is placed upside down. When the operating device is placed normally horizontally (is not placed upside down) (S2: NO), the CPU 11 displays a graphical user interface (GUI) for horizontal placement on the display device 7 at S3. When the operating device is placed upside down (S2: YES), the CPU 11 displays a graphical user interface for upside-down horizontal placement on the display device 7 at S4.
When the operating device 12 is not placed horizontally (S1: NO), the CPU 11 decides at S5 whether the attachment posture of the operating device 12 is in fore-and-aft orientation. When the attachment posture of the operating device 12 is in fore-and-aft orientation (S5: YES), the CPU 11 displays a graphical user interface for fore-and-aft orientation on the display device 7.
When the attachment posture of the operating device 12 is not in fore-and-aft orientation (S5: NO), the CPU 11 decides at S7 whether the attachment posture of the operating device 12 is in lateral and rightward (right downward) orientation. When the operating device is not oriented rightward (S7: NO), that is, when the operating device is oriented leftward (left downward), the CPU 11 displays a graphical user interface for leftward (left downward) orientation on the display device 7 at S8. When the operating device is oriented rightward (S7: YES), the CPU 11 displays a graphical user interface for rightward (right downward) orientation on the display device 7 at S9.
FIG. 4A and FIG. 4B show examples of display of a menu screen image of the navigation device 21 on the display device 7. Icons are displayed as a graphical user interface on the screen of the display device. For example, when the attachment posture of the operating device 12 is in fore-and-aft orientation, the CPU 11 displays, as in FIG. 4A, icons in a horizontal row on the screen of the display device 7 (S6).
In this case, when the rotatable knob 14 of the operating device 12 is rotated by the user in clockwise direction (rightward), a cursor (hatched in the drawing for convenience' sake) indicating a selected state of an icon (which one of icons is selected) moves rightward one by one on the basis of a signal indicating that the rotatable knob has been rotated in clockwise direction. In contrast, when the rotatable knob 14 is rotated by the user in counterclockwise direction (leftward), the cursor indicating the selected state of an icon moves leftward one by one on the basis of the signal indicating that the rotatable knob has been rotated in counterclockwise direction. A user moves the cursor to a target icon, and thereafter manipulates or presses the rotatable knob 14 for determination. When a determination signal is inputted to the operating device, the menu corresponding to the icon is determined.
In contrast, as in FIG. 4B, when the attachment posture of the operating device 12 is in lateral (rightward) orientation, the CPU 11 displays icons in a vertical column on the screen of the display device 7 (S9). In this case, when the rotatable knob 14 is rotated by the user in clockwise direction (rightward), the cursor indicating the selected state of an icon moves upward one by one. When the rotatable knob 14 is rotated by the user in counterclockwise direction (leftward), the cursor indicating the selected state of an icon moves downward one by one.
FIG. 5A and FIG. 5B show examples of display of a volume setting screen image of the audio device 22 on the display device 7. An indicator indicating an audio volume is displayed as a graphical user interface on the screen of the display device 7. In this case, as in FIG. 5A, when the attachment posture of the operating device 12 is in fore-and-aft orientation, the CPU 11 displays the indicator that extends in horizontal direction on the screen of the display device 7. In this case, when the rotatable knob 14 is rotated by the user clockwise (rightward), the display of the indicator changes to a higher volume indication (an indicator needle moves in a direction of increasing toward the right side of the indicator) on the basis of a signal signifying that the rotatable knob has been rotated clockwise. When the rotatable knob 14 is rotated by the user counterclockwise (leftward), the display of the indicator changes to a lower volume indication (the indicator needle moves in a direction of decreasing toward the left side of the indicator).
As in FIG. 5B, when the attachment posture of the operating device 12 is in lateral (rightward) orientation, the CPU 11 displays the indicator that extends in horizontal direction on the screen of the display device 7. In this case, when the rotatable knob 14 is rotated by the user clockwise (rightward), the display of the indicator changes to a higher volume indication (an indicator needle moves in a direction of increasing toward the upper side of the indicator) on the basis of a signal signifying that the rotatable knob has been rotated clockwise. When the rotatable knob 14 is rotated by the user counterclockwise (leftward), the display of the indicator changes to a lower volume indication (the indicator needle moves in a direction of decreasing toward the lower side of the indicator).
As mentioned above, according to the vehicle operating system 6 of the present embodiment, the operating device 12 (base 13) that can be used to perform selection manipulation to a graphical user interface (GUI) on the display device 7 for the purpose of controlling or instructing any one of the in-vehicle devices 21 to 23 can be attached to a position that conforms to the personal predilection of the user in the compartment 1 in an orientation that conforms to a personal predilection of the user. Thus, the vehicle operating system 6 of the present embodiment can satisfy various needs of the users.
In the operating device 12, the attachment posture of the operating device 12 is detected by the posture detection sensor 18. The attachment posture signal is inputted to the CPU 11 that controls the display device 7. Accordingly, the CPU 11 can display a graphical user interface in a form, which is corresponding to the attachment posture of the operating device 12, on the screen of the display device 7. As a result, according to the present embodiment, the operating device 12 for operating the in-vehicle devices 21 to 23 can be attached to a position that conforms to the personal predilection of the user in the compartment 1, and the display related to the operation can keep a user from feeling uncomfortable (makes a user feel less uncomfortable). Thus, the operating device 12 can secure an improved manipulation performance.
Second Embodiment
The following will describe a second embodiment of the present disclosure with reference to FIG. 6. FIG. 6 shows an outline arrangement of a vehicle operating system 31 according to the second embodiment. The vehicle operating system 31 includes, for example, a smartphone 32 serving as a hand-carried information device, and an operating device 12. The operating device 12 is similar to the operating device described in the first embodiment, and is designed to be attached to a position that conforms to the personal predilection of the user in the compartment 1. The same reference signs will be assigned to components equivalent to those of the first embodiment, and new illustration and an iterative description will be omitted.
A difference of the second embodiment from the first embodiment lies in a point that the operating device 12 is used to operate the smartphone 32 serving as a hand-carried information device carried into the compartment 1. As already known, the smartphone 32 includes a display device 33 formed on the face of the body of the smartphone 32, and the body of the smartphone 32 is equipped to a receiving unit of the instrument panel 2 in a detachable manner. The smartphone 32 includes a CPU (not shown), also includes navigation software and music software. The smartphone 32 implements a navigation function or music reproduction function on the basis of a selection manipulation performed by the user on a graphical user interface displayed on the screen of the display device 33.
Further, the smartphone 32 includes a communication unit (not shown) which is provided by a near field communication unit conformable to, for example, Wi-Fi or Bluetooth (registered trademark). The communication unit serves as a connection unit that connects the smartphone 32 with the communication unit 19 of the operating device 12 (perform wireless communication). The smartphone 32 includes an application program for connecting the smartphone to the operating device 12. By running the application program, the smartphone can be operated based on signals (rotation manipulation signal, determination signal, and attachment posture signal) sent from the operating device 12.
The smartphone 32 includes an embedded CPU that controls the screen of the display device 33. The CPU of the smartphone is similar to the CPU 11 of the in-vehicle device described in the first embodiment. That is, the CPU of the smartphone 32 functions as a display control unit that controls display of a graphical user interface (GUI) on the display device 33 in a form corresponding to an attachment posture signal produced by the posture detection sensor 18, and also functions as a selection display unit that controls display related to the selection manipulation performed on the graphical user interface on the basis of the rotation manipulation signal and the determination signal.
According to the second embodiment, when the smartphone 32 owned by a user is carried into the compartment 1 and placed on the instrument panel 2, the operating device 12 can be used to operate the smartphone 32. Similar to the first embodiment, the operating device 12 can be freely attached to a position that conforms to the personal predilection of the user in the compartment 1, and the display related to the manipulation made on the graphical user interface on the screen of the display device 33 of the smartphone 32 can keep a user from feeling uncomfortable (makes a user feel less uncomfortable). Accordingly, the operating device 12 can secure an improved manipulation performance.
In the second embodiment, the smartphone 32 is described as an example of a hand-carried information device that can be carried into the compartment 1 and can be used in the compartment 1. Except for the smartphone, a portable navigation device (PND) or a tablet type personal computer may be adopted as the hand-carried information device. By installing an application program, which is used to connect the hand-carried information device to the operating device 12, in the hand-carried information device, a vehicle operating system can be constructed as described above.
FIG. 7A to FIG. 10C show third embodiment to sixth embodiment of the present disclosure. In the third to sixth embodiments, examples of a display mode of a graphical user interface (GUI) on the screen of the display device 7 (for example, a menu screen image of the navigation device 21) other than the examples described in the first embodiment are presented. Even in the third to sixth embodiments, similar to the first embodiment, the operating device 12 can be freely attached to a position that conforms to the personal predilection of the user in the compartment 1, and displays, on the screen of the display device 7, a graphical user interface that keeps a user from feeling uncomfortable (make a user feel less uncomfortable). Accordingly, the improved manipulation performance of the operating device 12 can be ensured.
Third Embodiment
The third embodiment is shown in FIG. 7A and FIG. 7B. As shown in FIG. 7A, when the attachment posture of the operating device 12 is fore-and-aft orientation, icons expressing selectable menus are respectively displayed in a horizontal row on the screen of the display device 7. In this case, a cursor expressing which of the icons is selected is fixed to the center of the screen. When the rotatable knob 14 of the operating device 12 is rotated by the user clockwise (rightward), an entire screen image (multiple juxtaposed icons) is scrolled rightward.
When the rotatable knob 14 is rotated by the user counterclockwise (leftward), the entire screen image (juxtaposed icons) is scrolled leftward. Therefore, after a user manipulates or rotates the rotatable knob 14 so that an icon which the user wants to select comes to the center of the screen, the user manipulates or presses the rotatable knob 14 for determination.
In contrast, as in FIG. 7B, when the attachment posture of the operating device 12 is lateral (rightward) orientation, icons are displayed in a vertical column on the screen of the display device 7.
