Description

  The present invention relates to an operating device used by being mounted on a vehicle, and more particularly to an operating device capable of applying a reaction force based on a user operation to an operating knob.

  2. Description of the Related Art Conventionally, a technique for instructing operations on in-vehicle devices such as a navigation device, an air conditioner, and an audio on a display screen (hereinafter referred to as “vehicle screen”) mounted on a vehicle is known. This vehicle screen is composed of a liquid crystal display, for example, and the position of a selection item image such as a button displayed on the liquid crystal display is instructed, and the in-vehicle device is operated accordingly.

  In such a technique, it is preferable to dispose the vehicle screen at a position as far upward and as far as possible in front of the driver because the viewpoint movement during driving by the driver needs to be reduced. On the other hand, it is preferable to arrange the operation unit for instructing the position on the vehicle screen at the driver's hand.

  Therefore, a remote operation system in which the vehicle screen is arranged away from the operation unit has been put into practical use. Among such systems, there is a system in which the movable range of the operation knob of the operation unit corresponds to the vehicle screen on a one-to-one basis (absolute operation), and it is known to improve operability. Yes. That is, a cursor that is moved by the operation knob is displayed at the position of the vehicle screen corresponding to the operation knob, and the position of the vehicle screen is indicated by this cursor. At this time, a technology has been proposed in which a reaction force (resistance force or assist force) according to the display content of the vehicle screen is applied to the operation knob to tactilely support the driver's operation and improve operability. Yes.

  By the way, when a failure occurs in a part of such an operating device, it is a matter of course that operability cannot be improved. Therefore, it is preferable that a failure of the operating device can be found quickly. For example, the operation device is equipped with a photo interrupter for acquiring the amount of movement of the operation knob in the X direction and the Y direction. Conventionally, in order to find a failure of this photo interrupter, it corresponds to the position of the operation knob. There has been disclosed a technique for duty-controlling the brightness of a switch illumination LED based on an illumination pattern that is attached (see, for example, Patent Document 1).

JP 2010-111304 A

  However, since the prior art is for visually observing the change in the brightness of the LED for switch illumination, if the vehicle interior is bright, the subtle change in the brightness may be difficult to understand. As a result, there is a concern that quick failure diagnosis becomes difficult.

  It is possible to solve this problem by connecting the operating device to another device (such as a display). However, considering the shipping inspection before assembly to the vehicle in particular, the operating device alone may fail. It is desirable to be able to diagnose.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an operating device that enables quick failure diagnosis with a single device even in a bright environment.

  The operation device according to claim 1, which has been made to achieve the above object, has an operation range corresponding one-to-one with a vehicle screen that is a screen of a vehicle, and includes an operation knob, a photo interrupter, a motor unit, And a switch.

  The operation knob moves in at least the X direction and the Y direction within the operation range in response to an operation by the user. The operation knob may be a slide type or a tilt type. Further, the reason for “at least” is that an operation knob that can be pressed down can move in the Z direction.

The photo interrupter is a configuration for acquiring the movement amount of the operation knob. Thereby, the movement position in the operation range of the operation knob is acquired.
The motor unit applies a reaction force to the operation knob based on a signal from the photo interrupter. The “reaction force” here is not only based on, for example, a user operation, but also includes one for moving the operation knob regardless of the user operation.

  The switch is embodied as a push-down switch, for example. Specifically, a plurality of switches are arranged around the operation knob. However, including a case where a single switch is arranged, it is not limited to being arranged around the operation knob.

  Here, particularly in the present invention, a failure diagnosis process can be executed. In the failure diagnosis process, a failure is diagnosed by applying a reaction force to the operation knob in accordance with a user operation. The “user operation” includes not only an operation on the operation knob but also an operation on the switch.

  In other words, in the present invention, diagnosis is performed by applying a reaction force to the operation knob for any operation of the user. If it does in this way, a failure can be judged through tactile sense by operating an operation knob, or visually through the operation knob. As a result, even when the surroundings are bright, it is possible to perform quick failure diagnosis with the device alone. As a result, quick failure diagnosis is possible even when the vehicle interior is bright after the vehicle is mounted. Moreover, since the failure diagnosis can be performed with the device alone, the shipping inspection before the assembly to the vehicle is facilitated.

  Specifically, as shown in claim 2, the failure determination process includes a photo-interrupter diagnosis process for applying a resistance force as a reaction force that prevents the operation knob from moving according to the amount of movement of the operation knob. Illustrated. Since the photo interrupter is configured to acquire the movement amount of the operation knob, a reaction force corresponding to the movement amount is applied in the diagnosis. In this way, it is possible to detect a failure of the photo interrupter through the sense of touch.

  At this time, since diagnosis in the X direction and diagnosis in the Y direction can be considered, as shown in claim 3, in the photointerrupter diagnosis processing, the resistance force proportional to the amount of movement in each of the X direction and the Y direction. It is conceivable to apply to the operation knob. In other words, the greater the operating knob is moved in both directions, the greater the resistance is applied. In this way, the effect that the failure of the photo interrupter can be found through tactile sense is conspicuous.

  In addition, it is preferable that the X direction and the Y direction can be diagnosed separately. Therefore, as shown in claim 4, in the photo interrupter diagnosis process, the movement in the other direction is performed during the operation in one of the X direction and the Y direction, together with the resistance according to the movement amount of the operation knob. It is conceivable to provide resistance that can be hindered. For example, a reaction force that prevents movement to a range shown by hatching in FIG. 11C is applied. This makes it easy to move the operation knob in the X direction and the Y direction for each direction.

  Further, the failure determination process is specifically exemplified to include a switch diagnosis process for applying a reaction force that moves the operation knob in a predetermined pattern in response to pressing of the switch, as shown in claim 5. The That is, when the switch is pressed, the operation knob moves in a predetermined pattern. In this way, a switch failure can be found through vision.

  For example, as shown in claim 6, in the switch diagnosis process, it is conceivable to apply a reaction force to the operation knob so as to approach the pressed switch. In this case, on the assumption that a switch is arranged around the operation knob, the operation knob moves so as to approach the pressed switch. In this way, since the switch and the movement of the operation knob can be easily associated with each other, the effect that the failure of the switch can be found through vision is conspicuous.

  Further, as described in claim 7, when it is assumed that the switch has a unique illumination unit, the illumination unit may be turned on in the switch diagnosis process. The illumination unit is embodied as an LED provided for each switch, for example, and blinks at a predetermined cycle. In this way, diagnosis for the illumination unit can be performed in parallel. Further, in this case, unlike the prior art, since the luminance is not gradually changed, it can be sufficiently visually recognized even in a bright vehicle interior.

  By the way, since the photo interrupter diagnosis process and the switch diagnosis process diagnose the failure by the reaction force against the operation knob, it is assumed that the motor unit is normal. Therefore, as shown in claim 8, the failure diagnosis process may include a motor diagnosis process for imparting resistance to the operation knob. In this case, since it is only necessary to determine that the motor unit is normal, it is conceivable to always apply the same reaction force (for example, the maximum reaction force) to the operation knob regardless of the movement amount of the operation knob. In this way, a failure diagnosis of the motor unit can be performed.

  Further, since the motor diagnosis process is a premise of the photo interrupter diagnosis process and the switch diagnosis process, it is preferable that the motor diagnosis process is executed at the beginning of the failure diagnosis process as shown in claim 9. Thereby, the photo interrupter diagnosis and the switch diagnosis are made effective.

  Note that when the failure diagnosis process is performed, control different from normal control is performed. Therefore, as shown in claim 10, it is also possible to have a configuration capable of executing a diagnosis notification process that notifies at least one of the start and end of the failure diagnosis process by applying a reaction force to the operation knob by the motor unit. As a result, since the switching timing between the failure diagnosis process and the normal control is known, the convenience for the user is improved.

  For example, as shown in claim 11, in the diagnosis notification process, it is conceivable to apply a reaction force so as to move the operation unit in a predetermined pattern. This makes it easier to understand the start and end of the failure diagnosis process.

  For example, as shown in claim 12, on the assumption that the switch has a unique illumination unit, it is conceivable that the illumination unit is lit in a predetermined pattern in the diagnosis notification process. This makes it easier to understand the start and end of the failure diagnosis process.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a schematic configuration of a navigation device 1 according to the embodiment.
The navigation device 1 is configured around the vehicle-mounted device control unit 10. The vehicle-mounted device control unit 10 is used for overall control of each unit of the apparatus, and is configured as a well-known computer including a CPU, a ROM, a RAM, an I / O, a bus line connecting these components, and the like.

The on-vehicle device control unit 10 is electrically connected to the position detection unit 20, the data input unit 30, the audio output unit 40, the USB terminal 50, the operation unit 60, and the display unit 70.
The position detection unit 20 receives a transmission radio wave from a GPS (Global Positioning System) satellite and detects a position coordinate of the vehicle, and outputs a detection signal corresponding to the angular velocity of the rotational motion applied to the vehicle. The gyroscope is a vehicle speed sensor that outputs a detection signal corresponding to the vehicle speed. And the present location of a vehicle is detected by using each of these sensors complementing each other.

  The data input unit 30 is a device for reading various programs such as various programs stored in a storage medium such as a DVD-ROM and a hard disk drive, and map data for navigation processing.

  The voice output unit 40 is a device for notifying the user of various information by voice. Thereby, various information can be provided to the user both by the display by the display unit 70 and the sound output from the sound output unit 40.

Various external devices can be connected to the USB terminal 50, and a mobile terminal such as a smartphone can be connected to the USB terminal 50.
The operation unit 60 is a pointing device, and includes an operation knob 61, an operation control unit 62, a motor unit 63, a photo interrupter 64 that detects the amount of movement of the operation knob 61, a press detection sensor 65 that detects a press operation of the operation knob 61, And five push button type switches 66. In order to distinguish the five push button switches 66, the symbols “A switch 66”, “B switch 66”, “C switch 66”, “D switch 66” and “E switch 66” will be used below. ". Further, in order to instruct execution of diagnostic processing described later, it is assumed that the switches 66 of A to C are “switch group 1” and the switches 66 of D and E are “switch group 2”. . Furthermore, the switches 66 of A to C have LEDs as their own illumination parts.

The display unit 70 is a color display device having a vehicle screen 70 a such as a liquid crystal display, and displays various images on the vehicle screen 70 a in response to an input of a video signal from the vehicle-mounted device control unit 10.
Here, the arrangement of the operation unit 60 and the display unit 70 will be described.

  As shown in FIG. 2A, in the vehicle compartment, the display unit 70 is disposed at a position intermediate between the driver seat and the passenger seat on the dashboard 71 in front of the driver. The viewpoint movement when viewing the vehicle screen 70a of the display unit 70 is reduced. On the other hand, the operation unit 60 is disposed on the upper surface of the center console 80 immediately next to the driver's seat so that the driver can easily operate without extending his hand or changing his posture. .

  The operation knob 61 of the operation unit 60 is a slide type knob that is movable in a two-dimensional direction. FIG. 2B shows an appearance of the operation unit 60 as viewed from above. Here, the operation knob 61 is movable in the X and Y directions in FIG. 2B along a plane perpendicular to the axial direction of the shaft portion. The movable region of the operation knob 61 is a rectangular region having the same aspect ratio as that of the vehicle screen 70a (see FIG. 1). The operation knob 61 is also movable in the Z direction (vertical direction in the drawing) in FIG. 2B, and can be determined on the vehicle screen 70a.

  The operation control unit 62 detects the position of the operation knob 61 in the X direction and the Y direction based on a signal from the photo interrupter 64. Further, based on a signal from the press detection sensor 65, a press operation of the operation knob 61, that is, a determination operation by the operation knob 61 is detected. Furthermore, the operation control unit 62 controls the motor unit 63 and applies a reaction force to the operation knob 61. The reaction force here includes not only a reaction force according to a user operation but also a movement force of the operation knob 61 within the movable region.

  Such an operation control part 62 outputs the position in the movable area | region of the operation knob 61 to the onboard equipment control part 10 as operation data. At this time, the operation control unit 62 associates the position of the operation knob 61 in the movable region with the position on the vehicle screen 70a on a one-to-one basis. The in-vehicle device control unit 10 displays a cursor at a position corresponding to the movable area of the operation knob 16 based on the operation data. Will be moved (absolute operation).

  In addition, the operation control unit 62 outputs a pressing operation of the operation knob 61 to the in-vehicle device control unit 10 as operation data. Thereby, the onboard equipment control part 10 judges that determination operation in the cursor position was performed based on operation data.

  Furthermore, reaction force information defining a reaction force map is set in the operation control unit 62 from the vehicle-mounted device control unit 10. Accordingly, the operation control unit 62 applies a reaction force according to the reaction force information to the operation knob 61 via the motor unit 63.

Here, the reaction force information will be described.
The reaction force information is set, for example, as a matrix-like data table that has a one-to-one correspondence with the coordinates of the movable region of the operation knob 61.

  For example, FIG. 3 is a diagram schematically showing a reaction force map defined in the reaction force information set by the vehicle-mounted device control unit 10 and the position of the operation knob 61 corresponding to the cursor position. As shown in FIG. 3, pulling reaction force generation ranges H1, H2, and H3 (hatched areas) are set in ranges corresponding to the positions and shapes of individual buttons on the operation screen.

  The reaction force information defining the reaction force map shown in FIG. 3 is at the center of the generation range H1 to H3 (“+” in the drawing) when the cursor C is positioned within the pulling reaction force generation range H1 to H3. It is defined that the directed assist force is applied to the operation knob 61. This makes it easy to align the indication position of the cursor C with the button position.

  The present embodiment is characterized by failure detection in the operation unit 60. Therefore, next, a failure diagnosis process executed by the operation control unit 62 will be described. FIG. 4 is a flowchart showing the failure diagnosis process. This failure diagnosis process is executed by turning the ignition key of the vehicle.

In the first S100, a diagnosis mode transition process is executed. This process is a process for notifying the user of the transition to the diagnosis mode. Details will be described later.
In the next S110, motor diagnosis processing is executed. This process diagnoses the motor unit 63 (see FIG. 1) prior to each diagnosis process.

  In the next S120, it is determined whether or not a switch operation has been performed. This process determines whether any of the five switches 66 has been pressed. If it is determined that a switch operation has been performed, the process proceeds to S130. On the other hand, if there is no switch operation after a certain period of time (S120: NO), the normal mode return process is executed in S160, and then the failure diagnosis process is terminated.

  In S130, it is determined whether or not the operated switch is included in the switch group 1. The switch group 1 includes the switches 66 of A to C as described above. If it is determined that the switch group 1 has been operated (S130: YES), a photo-interrupter diagnosis process is executed in S140, and then the process from S110 is repeated. On the other hand, when the switch group 1 is not operated (S130: NO), that is, when it is determined that the switch group 2 is operated, the switch diagnosis process is executed in S150, and then the processes from S110 are repeated. .

Next, details of each process will be described.
The diagnostic mode transition processing in S100 is as shown in FIG.
In the first S101, the operation knob 61 is driven. In this process, as shown in FIG. 10A, the reaction force for moving the operation knob 61 in a pattern of the upper right corner → the upper left corner → the lower left corner → the lower right corner → the center portion. Is given.

In subsequent S102, the switch 66 is blinked. In this process, all the switches 66 of A to E are blinked at the same timing.
The motor diagnosis process in S110 is as shown in FIG.

  In the first S111, the maximum reaction force is generated. This process maximizes the resistance force, which is the reaction force in the direction of returning to the center, with respect to the operation of the operation knob 61. As a result, as shown in FIG. 10B, the operation knob 61 is fixed at the center.

  In subsequent S112, the switch group 1 and the switch group 2 are alternately blinked. That is, when the LEDs of the A to C switches 66 are lit, the LEDs of the D and E switches 66 are turned off, and when the LEDs of the A to C switches 66 are turned off, the D and E switches 66 are turned off. LED will be lit.

The photointerrupter diagnosis process in S140 that is shifted to when the switch group 1 is operated in S130 in FIG. 4 is as shown in FIG.
In first S141, it is determined whether or not the operation knob 61 has been moved by a user operation. This process acquires the amount of movement of the operation knob 61 in the X direction and the Y direction. The movement amount is acquired by the photo interrupter 64. If it is determined that the operation knob 61 has moved (S141: YES), the process proceeds to S142. On the other hand, if there is no movement of the operation knob 61 after a predetermined time has elapsed, the photo interrupter diagnosis process is terminated, and the process proceeds to S110 in FIG.

  In S142, in accordance with the movement amount acquired in S141, a resistance force that is a reaction force toward the center is applied to the operation knob 61. In this process, as shown in FIG. 10C, the greater the amount of movement from the center of the operation knob 61, the greater the resistance force.

Further, the switch diagnosis processing in S150 that is performed when the switch group 2 is operated in S130 in FIG. 4 is as shown in FIG.
In the first S151, the LED of the switch 66 is blinked. This process is the same as S102 in FIG. 5, and the LEDs of all the switches 66 of A to E are blinked at the same timing.

  In subsequent S152, it is determined whether or not any of the switches 66 of A to E is pressed. If it is determined that the switch 66 has been pressed (S152: YES), the process proceeds to S153. On the other hand, if the switch 66 is not pressed even after a predetermined time has elapsed (S152: NO), the switch diagnosis process is terminated, and the process proceeds to S110 in FIG.

  In S153, the operation knob is driven in accordance with the pressed switch 66. In this process, a reaction force is applied to move the operation knob 61 so as to approach the pressed switch 66. For example, as shown in FIG. 11A, when the A switch 66 is pressed, the operation knob 61 is moved closer to the A switch 66 as indicated by a two-dot chain line and an arrow. The same applies to the switches 66 of B to E.

Furthermore, the normal mode return processing in S160 that is shifted to when it is determined in S120 in FIG. 4 that there is no switch operation for a certain time is as shown in FIG.
In the first S161, the operation 61 knob is driven to return to the initial position. In this process, as shown in FIG. 11B, a reaction force is applied to move the operation knob 61 in a pattern of the lower right corner → the lower left corner → the upper left corner. In this embodiment, the initial position is the upper left corner.

In subsequent S162, normal control is started. In this process, the LED of the switch 66 and the control of the reaction force are returned to the normal control according to the state of the vehicle.
Next, the effect which the navigation apparatus 1 of this embodiment exhibits is demonstrated.

  In the present embodiment, when the switch group 1 is operated (S130 in FIG. 4: YES), a photo interrupter diagnosis process is executed in S140. In the photo interrupter diagnosis process, it is determined whether or not the operation knob 61 has moved. When the operation knob 61 has moved, a resistance force toward the center is applied to the operation knob 61 in accordance with the amount of movement of the operation knob 61. . Thereby, a failure of the photo interrupter 64 can be found through the sense of touch.

  In addition, at this time, as shown in FIG. 10C, a greater resistance is applied as the amount of movement of the operation knob 61 from the center increases. In other words, the greater the operating knob 61 is moved in each of the X direction and the Y direction, the greater resistance is applied. Thereby, the effect that the failure of the photo interrupter can be found through the sense of touch is conspicuous.

  In the present embodiment, when the switch group 2 is operated (S130 in FIG. 4: NO), a switch diagnosis process is executed in S150. In the switch diagnosis process, the LED of the switch 66 blinks. In this process, the LEDs of all the switches 66 of A to E are blinked at the same timing. Thereby, the diagnosis with respect to LED of the switch 66 can be performed in parallel. Further, in this case, since the luminance is not gradually changed, it is sufficiently visible even in a bright vehicle interior.

  In the switch diagnosis process, it is determined whether any one of the switches A to E is pressed. If it is determined that the switch 66 is pressed, the operation knob 61 is driven in accordance with the pressed switch 66. To do. That is, when the switch 66 is pressed, the operation knob 61 moves in a predetermined pattern. Thereby, a failure of the switch 66 can be found through vision.

  In addition, at this time, as shown in FIG. 11A, when the A switch 66 is pressed, the operation knob 61 approaches the A switch 66 as indicated by a two-dot chain line and an arrow. Thereby, since the switch 66 and the movement of the operation knob 61 are easily associated with each other, the effect that the failure of the switch 66 can be found through vision is conspicuous.

  In the present embodiment, prior to the photo interrupter diagnosis process (S140 in FIG. 4) and the switch diagnosis process (S150), the motor diagnosis process is executed in S110. In the motor diagnosis process, a maximum reaction force is generated. This processing maximizes the resistance force in the direction of returning to the center with respect to the operation of the operation knob 61. Thereby, failure diagnosis of the motor unit 63 can be performed. Further, since the motor diagnosis process (S110) is performed prior to the photo interrupter diagnosis process (S140) and the switch diagnosis process (S150), the effectiveness of diagnosis of the photo interrupter 64 and the motor unit 63 is ensured.

  Furthermore, in this embodiment, the diagnosis mode transition process (S100 in FIG. 4) is executed prior to diagnosis. In the diagnosis mode transition process, the operation knob 61 is driven in a predetermined pattern. Further, the LED of the switch 66 is blinked. In this embodiment, when the switch 66 is not operated even after a predetermined time has elapsed (S120), the normal mode return process (S160) is executed. In the normal mode return process, the operation knob 61 is driven in a predetermined pattern and returned to the initial position. Thereby, since the switching timing between the diagnostic processing and the normal control is known, the convenience for the user is improved.

  As described above, according to the present embodiment, a quick failure diagnosis can be performed as a function of the operation unit 60 even when the surroundings are bright. As a result, quick failure diagnosis is possible even when the vehicle interior is bright after the vehicle is mounted.

  In this embodiment, the operation unit 60 corresponds to an “operation device”, the vehicle screen 70a corresponds to a “vehicle screen”, the operation knob 61 corresponds to an “operation knob”, and the photo interrupter 64 corresponds to a “photo interrupter”. The motor unit 63 corresponds to a “motor unit”, the five A to E switches 66 correspond to “switches”, and the LED of each switch 66 corresponds to an “illuminating unit”.

  Further, the photo interrupter diagnosis process of S140 in FIG. 4 corresponds to the “photo interrupter diagnosis process”, and the switch diagnosis process of S150 corresponds to the “switch diagnosis process”. Further, the motor diagnosis process in S110 corresponds to “motor diagnosis process”, and the diagnosis mode transition process in S100 and the normal mode return process in S160 correspond to “diagnosis notification process”.

As mentioned above, this invention is not limited to the said embodiment at all, In the range which does not deviate from the summary, it can be implemented with a various form.
(A) For example, in the photo interrupter diagnosis process (S140) shown in FIG. 4, hatching is applied to FIG. 11C so that the operation knob 61 can be easily moved in either the X direction or the Y direction. Reaction force information that defines a reaction force map that prevents movement to the specified range may be set. This makes it easy to move the operation knob 61 in the X direction and the Y direction for each direction.

  (B) In the above embodiment, the failure diagnosis of the operation unit 60 mounted on the vehicle has been described. However, since the operation unit 60 of the present embodiment is configured to be able to perform a single inspection, the operation unit 60 is assembled to the vehicle. Faults can be easily diagnosed even at the previous shipping inspection stage. In this case, the failure diagnosis process shown in FIG. 4 may be executed by supplying power to the operation unit 60, for example.
