DETAILED DESCRIPTION OF THE INVENTION

[0010] The following description of the preferred embodiments will be given in detail with reference to the accompanying drawings. In the drawings used in the following description, the scale of each illustrated element is appropriately changed so that it can be recognized.

[0011] FIG. 1 illustrates an example of a cabin of a vehicle 20 equipped with a steering device 10 according to an embodiment. The steering device 10 is a device for causing the vehicle 20 to perform an operation (steering operation) to change the direction of travel. The steering device 10 is an example of a motion control device. The steering operation is an example of a first controlled operation. The vehicle 20 is an example of a moving body.

[0012] The steering device 10 includes a steering member 11. The steering member 11 has a shaft portion 111 and a grip portion 112.

[0013] The shaft portion 111 is configured to be able to rotate about a rotation axis A. The rotation axis A extends along the front-rear direction of the vehicle 20. The front-rear direction is an example of a reference direction.

[0014] The grip portion 112 is configured to be able to be held by the driver's hand. The driver is an example of a user. The grip portion 112 is configured to be able to turn along a turning path P centered on a turning axis A. When the grip portion 112 is turned by the driver's hand, the shaft portion 111 turns in the same direction. The direction of the turning corresponds to the changed traveling direction of the vehicle 20.

[0015] The steering device 10 includes an input device 12. The input device 12 is disposed between the shaft portion 111 and the grip portion 112 when viewed from the direction along the rotation axis A. The input device 12 is a device for causing the controlled device 30 mounted on the vehicle 20 to perform an operation other than a steering operation.

[0016] Examples of controlled devices 30 include audiovisual equipment, air conditioning equipment, lighting devices (headlights, turn signals, fog lights, interior lights, etc.), visibility improvement devices (wipers, cleaners, etc.), devices for adjusting the position of steering members or seats, power window devices, locking / unlocking devices, etc. The operation executed by controlled device 30 is an example of a second controlled operation.

[0017] 2 illustrates an example of the functional configuration of the steering device 10. The input device 12 has a detection surface 120. The detection surface 120 includes an operation reception area 121. The operation reception area 121 is configured to receive an operation for causing the controlled device 30 to perform a predetermined operation. The operation is performed by the driver's fingers holding the grip portion 112.

[0018] The input device 12 may be configured to detect contact or approach of a driver's finger with the detection surface 120. As an example, the input device 12 may be configured to detect a change in capacitance on the detection surface 120 that accompanies contact or approach of a driver's finger, and to output a first detection signal DS1 indicating that the driver's finger has contacted or approached the detection surface based on the change.

[0019] As another example, the input device 12 may be configured to detect a pressure change or displacement on the detection surface 120 due to contact with the driver's finger, and based on the change or displacement, output a first detection signal DS1 indicating that the driver's finger has contacted the detection surface 120.

[0020] The first detection signal DS1 is configured to include information indicating the position at which the driver's finger touches or approaches the detection surface 120. The first detection signal DS1 may be an analog signal or a digital signal depending on the specifications of the input device 12.

[0021] The steering device 10 includes a processing device 13. The processing device 13 may be built into the input device 12, or may be provided at an appropriate position independent of the input device 12.

[0022] The processing device 13 includes an input interface 131. The input interface 131 is configured as a hardware interface that receives the first detection signal DS1. When the first detection signal DS1 is an analog signal, the input interface 131 includes an appropriate conversion circuit including an A / D converter that converts the analog signal into a digital signal. This description also applies to other signals that can be received by the input interface 131, which will be described later.

[0023] The processing device 13 includes a processor 132 and an output interface 133. The processor 132 is configured to output a first control signal CS1 from the output interface 133 in response to the first detection signal DS1. The first control signal CS1 is configured to cause the controlled device 30 to perform an operation corresponding to the operation input to the operation receiving area 121.

[0024] That is, the output interface 133 is configured as a hardware interface capable of outputting the first control signal CS1. The first control signal CS1 may be an analog signal or a digital signal depending on the specifications of the controlled device 30. When the first control signal CS1 is an analog signal, the output interface 133 includes an appropriate conversion circuit including a D / A converter. This description similarly applies to other signals that can be output by the output interface 133, which will be described later.

[0025] The steering device 10 includes a detection device 14. The detection device 14 is configured to output a second detection signal DS2 corresponding to the position of the driver's hand on the grip portion 112 of the steering member 11.

[0026] For example, as illustrated in FIG. 3, the detection device 14 can be realized by a plurality of electrodes arranged on the grip portion 112 so as to detect a change in capacitance accompanying contact or approach of the driver's hand 40.

[0027] Alternatively, the detection device 14 may be realized by a plurality of piezoelectric sensors arranged on the grip portion 112 so as to detect pressure changes or displacements caused by contact with the driver's hand 40 .

[0028] 2, the second detection signal DS2 output from the detection device 14 is received by the input interface 131 of the processing device 13. The processor 132 is configured to output a second control signal CS2 for changing the position of the operation reception area 121 of the input device 12 from the output interface 133, in accordance with the position of the driver's hand 40 indicated by the second detection signal DS2.

[0029] 4, the input device 12 according to this embodiment includes a display device 122 capable of displaying images. In this embodiment, the input device 12 provides a graphical user interface (GUI) for controlling the operation of the audiovisual equipment. The display device 122 displays an image corresponding to the content to be played.

[0030] The display device 122 has a touch panel function. That is, the surface of the display device 122 forms the detection surface 120. The operation reception area 121 is displayed on the display device 122 as a button image for receiving a touch operation that causes the audiovisual device to perform a predetermined operation (play, stop, skip forward, etc.). The touch operation can be performed by the driver moving his / her fingers 41 while gripping the grip portion 112 of the steering member 11.

[0031] Specifically, the processor 132 of the processing device 13 identifies a first contact area CA1 on the detection surface 120 where the driver's hand 40 is in contact, based on the first detection signal DS1. On the other hand, the processor 132 identifies a second contact area CA2 on the grip portion 112 where the driver's hand 40 is in contact, based on the second detection signal DS2.

[0032] The position of the hand 40 in the grip portion 112 can be appropriately identified based on the second detection signal DS2 corresponding to the detection result by at least one electrode or piezoelectric sensor arranged in the grip portion 112. When the second detection signal DS2 corresponds to the detection results by a plurality of electrodes or piezoelectric sensors, the reference position of the hand 40 can be identified by applying an appropriate calculation. Examples of the reference position include the center of gravity position, the top end position, and a position corresponding to the base of the thumb.

[0033] The processor 132 determines whether the distance between the first contact area CA1 and the second contact area CA2 exceeds a predetermined threshold. The distance may be specified as the distance between a first reference point defined for the first contact area CA1 and a second reference point defined for the second contact area CA2. Examples of the first and second reference points include the center of the first contact area CA1 and the center of the second contact area CA2, respectively. Note that the first and second reference points may be defined differently.

[0034] If it is determined that the distance exceeds the threshold, the processor 132 regards the contact with the first contact area CA1 as an operation input. In this example, the first contact area CA1 is located on the operation reception area 121, so a touch operation on the operation reception area 121 is accepted.

[0035] As illustrated in Fig. 5, depending on how the driver holds the grip portion 112, a part of the hand 40 may come into contact with the detection surface 120 of the input device 12. Fig. 6 illustrates the first contact area CA1 and the second contact area CA2 identified in the above manner in this case.

[0036] In this example, if the distance between the first contact area CA1 and the second contact area CA2 does not exceed the threshold, the processor 132 does not regard the contact with the first contact area CA1 as an operation input, and outputs a second control signal CS2 from the output interface 133 to change the position of the operation reception area 121 so as to avoid the first contact area CA1.

[0037] As a result, the display position of the operation reception area 121 is changed to the left of the initial position illustrated in FIG.

[0038] 7 illustrates a case where the first contact area CA1 is larger. In this case, the processor 132 does not regard the contact with the first contact area CA1 as an operation input, and outputs the second control signal CS2 from the output interface 133 to change the position of the operation reception area 121 so as to avoid the first contact area CA1.

[0039] In this example, in addition to the position of the operation reception area 121, the size of the operation reception area 121 is also changed. Specifically, the size of the operation reception area 121 is reduced from the initial state illustrated in FIG. 4 so as to avoid the first contact area CA1.

[0040] The configuration according to this embodiment can prevent the driver's hand 40 holding the grip portion 112 from unintentionally touching the operation reception area 121 and performing an unwanted operation input. Therefore, it is possible to improve the convenience of the input device 12 that is mounted on the steering device 10 held by the driver's hand and receives an operation input for controlling the operation of the controlled device 30 by the hand.

[0041] Additionally, in this embodiment, the contact area of ​​the hand 40 that is the target of the avoidance process in the operation reception area 121 is identified using both the first detection signal DS1 output from the input device 12 and the second detection signal DS2 output from the detection device 14. In other words, the contact area is identified by cooperation between the input device 12 and the detection device 14.

[0042] According to this configuration, it is possible to identify the positional relationship between the first contact area CA1 corresponding to the contact position of the hand 40 on the input device 12 and the second contact area CA2 corresponding to the contact position of the hand 40 on the grip portion 112, thereby making it possible to more accurately discriminate unintentional contact with the operation reception area 121. In addition, since contact of the hand 40 with the input device 12 is permitted, restrictions on the position and size of the input device 12 disposed between the shaft portion 111 and the grip portion 112 can be relaxed.

[0043] However, the operation reception area 121 may be changed based on only the second detection signal DS2 output from the detection device 14.

[0044] 3, the hand 40A indicated by the two-dot chain line is gripping a portion of the grip portion 112 that is above the reference position. In this case, as illustrated in FIG. 8, the second contact area CA2 identified based on the second detection signal DS2 is located above the case illustrated in FIG. 4.

[0045] The processor 132 of the processing device 13 outputs a second control signal CS2 from the output interface 133 to change the display position of the operation reception area 121 so that the distance between the operation reception area 121 and the second contact area CA2 increases. As a result, the display position is changed so that the center position of the operation reception area 121 moves downward from the initial state illustrated in Fig. 4. This makes it difficult for the fingers of the driver, who is holding a relatively upper part of the grip part 112, to reach the operation reception area 121.

[0046] 3, the hand 40B indicated by the two-dot chain line is gripping a portion of the grip portion 112 that is lower than the reference position. In this case, as illustrated in FIG. 9, the second contact area CA2 identified based on the second detection signal DS2 is located lower than in the case illustrated in FIG.

[0047] The processor 132 of the processing device 13 outputs a second control signal CS2 from the output interface 133 to change the display position of the operation reception area 121 so that the distance between the operation reception area 121 and the second contact area CA2 increases. As a result, the display position is changed so that the center position of the operation reception area 121 moves upward from the initial state illustrated in Fig. 4. This makes it difficult for the fingers of the driver, who is holding a relatively lower part of the grip part 112, to reach the operation reception area 121.

[0048] The processor 132 of the processing device 13 having the various functions described above can be realized by a dedicated integrated circuit such as a microcontroller, ASIC, FPGA, etc., which has a storage element in which a computer program for realizing the functions is pre-installed. The storage element is an example of a non-transitory computer-readable medium on which a computer program is stored.

[0049] The processor 132 may be realized by a general-purpose microprocessor operating in cooperation with general-purpose memory. Examples of the general-purpose microprocessor include a CPU, an MPU, and a GPU. Examples of the general-purpose memory include a ROM and a RAM. In this case, a computer program for realizing the function may be stored in the ROM. The general-purpose memory is an example of a non-transitory computer-readable medium on which a computer program is stored. The general-purpose microprocessor specifies at least a portion of the program stored in the ROM, expands it in the RAM, and executes the above-described processing in cooperation with the RAM. The processor 132 may be realized by a combination of a dedicated integrated circuit and a general-purpose microprocessor.

[0050] The configurations referred to above are merely examples for facilitating understanding of the present disclosure. Each configuration example can be appropriately modified or combined with other configuration examples within the scope of the present disclosure.

[0051] In the above embodiment, the input device 12 includes the display device 122 capable of displaying an image, and the operation reception area 121 is provided as a part of the image. With such a configuration, not only can GUIs for controlling the operations of various controlled devices 30 be provided through the common display device 122, but also the position of the operation reception area 121 can be easily changed and the driver can be informed of the change. Therefore, the versatility of the input device 12 can be improved.

[0052] However, the input device 12 may be configured as a touchpad device that does not include a display device. In this case, the input device 12 is configured to detect a change in capacitance on the detection surface 120 due to contact with or approach of the driver's finger, and to output a first detection signal DS1 indicating that the driver's finger has contacted or approached the detection surface based on the change.

[0053] The operation reception area 121 is provided as at least a part of the detection surface 120. The position of the operation reception area 121 can be changed by performing at least one of a process of making undetectable at least a part of the area where contact or approach of a finger is detectable, and a process of making detectable at least a part of the area where contact or approach of a finger is undetectable.

[0054] In the above embodiment, the position of the operation reception area 121 is changed according to the position of the driver's hand holding the grip portion 112. In addition to or instead of this, at least one of the shape and size of the operation reception area 121 may be changed.

[0055] In the above embodiment, the detection device 14 is disposed on the steering member 11 and detects the position of the driver's hand 40 on the grip portion 112. However, the detection device 14 does not necessarily have to be disposed on the steering member 11. The detection device 14 may be realized by an imaging device disposed at an appropriate position in the passenger compartment of the vehicle 20. In this case, the processor 132 of the processing device 13 identifies the position of the driver's hand 40 on the grip portion 112 based on the second detection signal DS2 corresponding to the image of the steering member 11 acquired by the imaging device.

[0056] In the above embodiment, the input device 12 is disposed between the shaft 111 of the steering member 11 and the grip portion 112 that is held by the driver's right hand 40. Additionally or alternatively, as illustrated in Fig. 3, the input device 12 may be disposed between the shaft 111 and the grip portion 112 that is held by the driver's left hand 40L. In this case, the steering device 10 includes a detection device 14A that detects the position of the driver's left hand 40L on the grip portion 112.

[0057] The shape of the steering member 11 does not need to be annular. The shape of the steering member 11 can be any shape as long as it is possible to define the turning path P of the grip portion 112 centered on the turning axis A. The grip portion 112 may have a shape in which the portion to be held by the driver's left hand and the portion to be held by the driver's right hand are separate.

[0058] The input device 12 may also be mounted on a steering device for changing the direction of travel of a moving body other than the vehicle 20. Examples of such moving bodies include railways, ships, and aircraft. The operation of the controlled device 30 controlled by the input device 12 may be determined appropriately according to the specifications of the moving body.

[0059] The moving object does not necessarily have to have a physical entity. The steering device 10 may be mounted on a simulator that simulates the movement of the moving object. In this case, the steering member 11 is used to change the direction of travel of the virtual moving object simulated by the simulator. The input device 12 is used to control the movement of the virtual controlled device simulated by the simulator.

[0060] The input device 12 does not need to be mounted on a steering device of a moving object. For example, a controller having a shaft portion 111 and a grip portion 112 can be used to control the movement of an object displayed on a display of a shooting game device in an amusement facility. The input device 12 can be used by a user to select one of multiple functions executable by the object and perform an action associated with the selected function. In this case, the controller is an example of an action control device. The movement of the object is an example of a first controlled action. The action associated with each function executable by the object is an example of a second controlled action.
