  Here, when the driver operates the operating device that can present feedback, it is considered that the driver is less aware of the feedback presented by the operating device than an occupant seated in the passenger seat. For example, when the vehicle is traveling, the driver concentrates on driving as the speed of the vehicle increases, so the degree of feedback recognition decreases. Also, for example, when the sound inside the vehicle is loud, the driver's feedback recognition level decreases in proportion to the loudness. Like the conventional display device, when the reaction force pattern is different between the driver and the passenger seat, the feedback may be too uncomfortable when the speed is low or the sound inside the vehicle is low. , The feedback is too weak and the awareness of the feedback is lowered, which may reduce the operability.

  Therefore, an object of the present invention is to provide a feedback device that presents an appropriate feedback according to the state of the vehicle.

Note that the rotation includes rotation in the opposite direction, not rotation in one direction, unless otherwise specified.

  The second carriage 302 is composed of an outer U-shaped member in which a flat plate portion in which a hole into which the shaft 20 is inserted is formed and an arm portion orthogonal to the flat plate portion are integrally formed. The hole of the second carriage 302 is formed long along the Y direction, and is configured to allow movement of the shaft 20 in the Y direction.

  The gate block 312 is a box-shaped strength member having a square opening on the upper surface. The gate block 312 is provided to limit the tilting operation of the shaft 20 to a predetermined range. That is, the other end portion of the shaft 20 is inserted into the opening of the gate block 312, and the other end portion contacts the inner wall of the gate block 312 at a position where the shaft 20 tilts at the maximum stroke. The movement of the shaft 20 is restricted.

  The sector gear 314 and the sector gear 316 are each provided with a rotation shaft at one end of the fan shape, and gear teeth 314a and gear teeth 316a are formed on a part of the peripheral surface portion having the same radius around the rotation shaft. ing.

  The sector gear 314 is rotatable by attaching a rotation shaft to a frame (not shown) of the drive unit 3, and the arm portion of the second carriage 302 is coaxially connected. The motor gear 324a of the X motor 324 meshes with the gear teeth 314a of the sector gear 314. The rotation sensor 322 includes, for example, a rotation encoder unit that rotates while being connected to the motor gear 324a, and a photodetector that counts the number of rotations to detect a rotation angle or a rotation position.

  The rotation axis of the sector gear 316 is connected to one Y axis 306 of the first carriage 300. The motor gear 326a of the Y motor 326 is engaged with the gear teeth 316a of the sector gear 316. The rotation sensor 328 includes, for example, a rotation encoder unit that rotates while being connected to the motor gear 326a, and a photodetector that counts the number of rotations to detect a rotation angle or a rotation position.

  Here, the two rotation sensors 322 and 328 are constituted by a light detection type encoder using a photodetector. Further, the rotation sensor 322 and the rotation sensor 328 may be a magnetic detection type encoder using a magnetoresistive effect element (MR element).

  The rotation sensor 322 and the rotation sensor 328 output angle information that is two pulses having different phases according to the rotation of the X motor 324 and the Y motor 326, for example. The control unit 7 calculates the rotation direction and the rotation amount of the X motor 324 and the Y motor 326 based on the angle information, and the tilt direction and the operation amount on the XY plane of the tilt operation of the operation unit 2 based on the calculated result. To calculate operation information.

  The case member 8 includes a box-shaped case frame 80 that houses the drive unit 3 therein, and a guide dome 81 that protrudes from the upper surface of the case frame 80 and is integrally formed. A substantially rectangular opening 82 is formed at the top of the guide dome 81.

  One end of the shaft 20 attached to the drive unit 3 is inserted into the opening 82 of the guide dome 81 from the inside of the case member 8 and attached to the support column 22 of the operation knob 21. At this time, the operation knob 21 is attached so that the guided surface which is the lower surface of the cover portion 23 is supported by the upper surface of the guide dome 81 and moves in the XY direction with respect to the upper surface.

  When the operation knob 21 is tilted in the X direction and the shaft 20 is tilted, the sector gear 314 connected to the second carriage 302 and the second carriage 302 with the rotation axis aligned is rotated. Accordingly, since the motor gear 324a meshed with the gear teeth 314a of the sector gear 314 rotates, the rotation operation of the shaft 20 in the X direction is detected by the rotation sensor 322 based on the rotation angle. Similarly, when the operation knob 21 is tilted in the Y direction, the first carriage 300 and the sector gear 316 coupled thereto rotate. Along with this, the motor gear 326a meshing with the gear teeth 316a of the sector gear 316 rotates, and the tilting operation of the shaft 20 in the Y direction is detected by the rotation sensor 328 based on the rotation angle.

  Further, when a drive signal is input to the X motor 324, torque for tilting in the X direction is transmitted to the shaft 20 and the operation knob 21 via the motor gear 324a, the sector gear 314, and the second carriage 302. Similarly, when a drive signal is input to the Y motor 326, torque for tilting in the Y direction is transmitted to the shaft 20 and the operation knob 21 via the motor gear 326a, the sector gear 316, and the first carriage 300. The control unit 7 outputs drive signals to the X motor 324 and the Y motor 326, and performs feedback control based on the tilt direction and the operation amount of the operation knob 21 detected by the rotation sensor 322 and the rotation sensor 328.

This reaction force is a first reaction force, a second reaction force, and a third reaction force in ascending order. Note that the types of reaction force described above are examples, and may be further divided into a plurality of types.

  Further, the reaction force may not change its strength, but may change the length of time the reaction force is presented. Further, the reaction force may be a combination of strength and the length of time presented.

(Configuration of output unit 4)
As illustrated in FIG. 2, the output unit 4 includes a speaker 40 and a speaker 41 and is schematically configured. The speaker 40 is arrange | positioned at the right door 91, as shown in FIG.1 (b). Moreover, the speaker 41 is arrange | positioned at the left door 92, as shown in FIG.1 (b).

  The speaker 40 and the speaker 41 are configured to output sound effects based on an output signal output from the control unit 7. The sound effect is, for example, a single frequency sound.

  The feedback device 1 is configured to output two types of sound effects, a first sound effect (small) for a low environmental sound and a second sound effect (large) for a large environmental sound. Has been. The sound effects are a first sound effect and a second sound effect in ascending order. Note that the types of sound effects are examples, and may be further divided into a plurality of types, or the sound types may be changed for each sound effect.

  This sound effect may be, for example, a sound that is continuously output while the operation is continued, or may be a sound that is output intermittently. Moreover, the kind of sound effect is not limited to the above, You may comprise so that it can set. Furthermore, the sound effect may be changed by the driver and the occupant.

  In the present embodiment, the sound effect is changed depending on the speed and the environmental sound, but may be different sounds for the driver and the occupant. When the driver is operating, a sound effect is output from the speaker 40 of the right door 91 on the driver's seat side. When the driver is operating, a sound effect is output from the speaker 41 of the left door 92 on the passenger seat side. May be output.

(Configuration of vehicle information generation unit 5)
The vehicle information generation unit 5 is configured to generate vehicle information 50 as shown in FIG. The vehicle information generation unit 5 generates vehicle information 50 based on, for example, the speed of the vehicle 9 and sound inside the vehicle (hereinafter referred to as environmental sound). This environmental sound is a sound measured inside the vehicle 9. Therefore, the environmental sound includes sound outside the vehicle measured inside the vehicle.

  In addition, the vehicle information generation part 5 may be comprised so that the information regarding a speed and an environmental sound may be acquired from the vehicle control part of the vehicle 9, for example, and the vehicle information 50 may be produced | generated, or a speed and an environmental sound are measured. The vehicle information 50 may be generated.

(Configuration of determination unit 6)
The determination unit 6 is schematically configured to determine whether a person who operates the operation unit 2 is a driver or an occupant seated in a passenger seat.

  Specifically, the determination unit 6 analyzes an image based on the imaging information output from the camera 60, and determines whether the person who operates the operation unit 2 is a driver or an occupant. It is configured.

  For example, the determination unit 6 uses a known method for determining a person who operates based on whether the hand holding the operation knob 21 of the operation unit 2 extends from the driver seat side or the passenger seat side. Use to determine. The determination method is not limited to the above method, and may be another known method.

  As an example, the camera 60 is disposed on an upper portion of the instrument panel 93 of the vehicle 9, and is configured to be able to image the periphery of the operation unit 2 disposed on the center console 90.

  As an example, the camera 60 is configured using an image sensor such as a CCD image sensor (Charge Coupled Device Image Sensor) and a CMOS image sensor (Complementary Metal Oxide Semiconductor Image Sensor). The camera 60 is configured to output imaging information obtained by imaging in accordance with a camera control signal output from the control unit 7 based on a clock signal to the determination unit 6.

(Configuration of control unit 7)
The control unit 7 includes, for example, a CPU (Central Processing Unit) that performs operations and processing on acquired data according to a stored program, a RAM (Random Access Memory) that is a semiconductor memory, a ROM (Read Only Memory), and the like. Microcomputer. In this ROM, for example, a program for operating the control unit 7 is stored. For example, the RAM is used as a storage area for temporarily storing calculation results and the like. The control unit 7 has means for generating a clock signal therein, and operates based on this clock signal.

  The control unit 7 stores a threshold value 70 and a feedback pattern 71 as shown in FIG. The threshold value 70 is used for determining whether the vehicle 9 is slow or fast and determining whether the environmental sound is low or high. The control unit 7 is configured to determine the speed and the environmental sound by comparing the acquired vehicle information 50 and the threshold value 70.

  As an example, the control unit 7 determines that the speed of 40 km / h or less is slow based on the threshold 70 and determines that the speed faster than 40 km / h is fast, but is not limited thereto. The threshold value 70 may be further divided into a plurality of values, for example.

  As an example, the control unit 7 determines that the environmental sound of 60 db or less is low and determines that the environmental sound higher than 60 db is high based on the threshold 70, but is not limited thereto. The threshold value 70 may be further divided into a plurality of values, for example.

  Here, when the driver is operating the operation unit 2, for example, the control unit 7 controls the drive unit 3 so as to generate a reaction force larger than the reaction force when the occupant is operating. In addition, when the driver is operating the operation unit 2, the control unit 7 controls the drive unit so as to generate a large reaction force corresponding to the speed, for example. In the present embodiment, the large reaction force corresponding to the speed indicates the reaction force “medium” of the driver when the speed is low and the reaction force “high” of the driver when the speed is high.

  The control unit 7 also provides the reaction force applied to the operation unit 2 based on the determination result obtained from the determination unit 6, the determination result of the speed and the environmental sound, and the feedback pattern 71, and the effect output from the output unit 4. Determine the sound. The feedback pattern 71 uses, for example, a feedback pattern as a table. Hereinafter, a combination of the reaction force and sound effect of the driver and the occupant will be described with reference to the feedback pattern 71 shown in FIG.

In the case of slow speed and low environmental sound In this case, when the operator is a driver, the control unit 7 generates a drive signal with a reaction force of “medium” and outputs the drive signal to the drive unit 3 to obtain a sound effect. Is generated and output to the output unit 4. In addition, when the operator is an occupant, the control unit 7 generates a drive signal that makes the reaction force “small” and outputs it to the drive unit 3, and generates an output signal that makes the sound effect “small”. Output to the output unit 4.

  In the above case, the environmental sound is “small” for both the driver and the occupant, but the reaction force is different between the driver and the occupant. This is because the operation load when operating the operation unit 2 is different between the driver and the occupant. That is, when the driver is driving the vehicle 9, the driver operates the operation unit 2 while operating the vehicle 9, so that the driver can operate the operation unit 2 as compared with the case where the occupant operates the operation unit 2. Reduces concentration. Therefore, the control unit 7 recognizes the operation without increasing the concentration of the operation on the operation unit 2 by increasing the reaction force more than when the occupant operates so that the operation feeling is easier to obtain than the occupant. It is easy to improve operability.

When the speed is slow and the environmental sound is loud In this case, when the operator is a driver, the control unit 7 generates a drive signal with a reaction force of “medium” and outputs the drive signal to the drive unit 3 to obtain a sound effect. Is generated and output to the output unit 4. In addition, when the operator is an occupant, the control unit 7 generates a drive signal that makes the reaction force “small” and outputs it to the drive unit 3, and generates an output signal that makes the sound effect “large”. Output to the output unit 4.

  In the above case, the sound effect is “high” for both the driver and the occupant. This is because it is considered that the sound effect cannot be heard when the sound inside the vehicle is loud. Therefore, when the control unit 7 compares the threshold value 70 with the vehicle information 50 and determines that the environmental sound is “high”, the control sound 7 sets the sound effect to “high”.

In the case of speed / speed and low environmental sound In this case, when the operator is a driver, the control unit 7 generates a driving signal for setting the reaction force to “high” and outputs the driving signal to the driving unit 3, and the sound effect Is generated and output to the output unit 4. In addition, when the operator is an occupant, the control unit 7 generates a drive signal that makes the reaction force “small” and outputs it to the drive unit 3, and generates an output signal that makes the sound effect “small”. Output to the output unit 4.

  In the above case, when the operator is a driver, the reaction force is “large” which is larger than “medium”. In this case, since the speed of the vehicle 9 is high, the operator concentrates more on the operation of the vehicle 9 than in the case where the vehicle 9 is slow, so that the concentration power on the operation of the operation unit 2 is reduced. Accordingly, the control unit 7 generates a reaction force larger than that when the speed is low, thereby making it easy to recognize the operation without increasing the concentration of the operation on the operation unit 2 and improving the operability. .

In the case of speed / speed and high environmental sound In this case, when the operator is a driver, the control unit 7 generates a driving signal for setting the reaction force to “high” and outputs the driving signal to the driving unit 3, and the sound effect Is generated and output to the output unit 4. In addition, when the operator is an occupant, the control unit 7 generates a drive signal that makes the reaction force “small” and outputs it to the drive unit 3, and generates an output signal that makes the sound effect “large”. Output to the output unit 4.

  In the above case, the sound effect is “high” for both the driver and the occupant. This is because it is considered that the sound effect cannot be heard when the sound inside the vehicle is loud. Therefore, when the control unit 7 compares the threshold value 70 with the vehicle information 50 and determines that the environmental sound is “high”, the control sound 7 sets the sound effect to “high”.

  Further, the control unit 7 is configured to calculate the tilt direction and the operation amount of the operation unit 2 based on the angle information, and output as operation information.

  Next, the operation of the feedback device 1 will be described with reference to the flowchart of FIG.

(Operation)
The control unit 7 of the feedback device 1 acquires angle information from the drive unit 3 when the vehicle 9 is powered on. The control unit 7 determines whether or not the operation unit 2 has been operated based on the acquired angle information. When the control unit 7 determines that the operation unit 2 is operated (S1: Yes), that is, when “Yes” in Step 1 is established, the control unit 7 generates a camera control signal, outputs the camera control signal, and generates a control signal. Output to the determination unit 6.

  The camera 60 images the periphery of the operation unit 2 based on the acquired camera control signal, and outputs imaging information to the determination unit 6 (S2).

  The determination unit 6 determines whether the person operating based on the imaging information acquired from the camera 60 is a driver or an occupant, and outputs the determination result as determination information to the control unit 7 (S3).

  The control unit 7 acquires the vehicle information 50 from the vehicle information generation unit 5 after acquiring the determination information. The control unit 7 determines a reaction force to be applied to the operation unit 2 based on the acquired determination information and vehicle information, and the read feedback pattern 71, and a sound effect to be output from the output unit 4, and outputs a drive signal and an output. A signal is generated and output (S4).

  The drive unit 3 generates a reaction force based on the acquired drive signal, and the output unit 4 outputs sound effects from the speaker 40 and the speaker 41 based on the acquired output signal (S5).

  The reaction force and sound effect are output while the operator continues the operation.

  Here, although the feedback apparatus 1 of this Embodiment determined presence of the person who operates based on angle information, it is not limited to this. For example, the feedback apparatus 1 determines the presence of a person who operates the operation unit 2 by analyzing an image captured after the determination unit 6 is turned on, and operates after the presence is determined. It may be configured to determine whether the driver is a driver or a passenger.

(Effect of embodiment)
The feedback device 1 according to the present embodiment can present an appropriate feedback according to the state of the vehicle. Specifically, since the feedback device 1 changes the reaction force according to the person who operates the operation unit 2, it is possible to apply a reaction force suitable for each, and the operational feeling is improved. Moreover, since the feedback apparatus 1 changes a driver's reaction force according to the speed of the vehicle 9, it can provide reaction force according to the operation load by driving | operation, and operation feeling improves further. Furthermore, since the feedback device 1 can change the sound effect according to the environmental sound, the sound effect can be recognized at an appropriate volume.

  Note that there are several possible variations of the feedback pattern. Below, an example of a modification is described.

(Modification 1)
FIG. 4A is a schematic diagram of a feedback pattern according to the first modification. In the first modification, the feedback to be presented is only the reaction force. Hereinafter, the reaction force presented to the driver and the occupant in Modification 1 will be described with reference to the feedback pattern shown in FIG.

In the case of slow speed, low environmental sound, low speed, high environmental sound In this case, when the operator is a driver, the control unit 7 generates and drives a drive signal with a reaction force of “medium” Output to part 3. Further, when the operator is an occupant, the control unit 7 generates a drive signal for setting the reaction force to “small” and outputs the drive signal to the drive unit 3.

  In the above case, the difference in reaction force is due to the fact that the driver and the occupant have different operation loads when operating the operation unit 2. Therefore, the control unit 7 recognizes the operation without increasing the concentration of the operation on the operation unit 2 by increasing the reaction force more than when the occupant operates so that the operation feeling is easier to obtain than the occupant. It is easy to improve operability.

In the case of speed / speed, low environmental sound, high speed / high environmental sound In this case, when the operator is a driver, the control unit 7 generates and drives a drive signal that sets the reaction force to “high”. Output to part 3. Further, when the operator is an occupant, the control unit 7 generates a drive signal for setting the reaction force to “small” and outputs the drive signal to the drive unit 3.

  In the above case, when the operator is a driver, the reaction force is “large” which is larger than “medium”. In this case, since the speed of the vehicle 9 is high, the operator concentrates more on the operation of the vehicle 9 than in the case where the vehicle 9 is slow, so that the concentration power on the operation of the operation unit 2 is reduced. Accordingly, the control unit 7 generates a reaction force larger than that when the speed is low, thereby making it easy to recognize the operation without increasing the concentration of the operation on the operation unit 2 and improving the operability. .

  Subsequently, Modification 2 will be described below.

(Modification 2)
FIG. 4B is a schematic diagram of a feedback pattern according to the second modification. In the second modification, the feedback to be presented is only sound effects. Hereinafter, sound effects presented to the driver and the occupant in Modification 2 will be described with reference to the feedback pattern shown in FIG.

-In the case of slow speed, low environmental sound, low speed, low environmental sound In this case, the control unit 7 outputs that the sound effect is "low" regardless of whether the operator is a driver or a passenger. A signal is generated and output to the output unit 4.

  In the above case, the environmental sound is “small” for both the driver and the passenger. This is because when the environmental sound is low, the operation load on the driver and passengers is small.

In the case of slow speed, environmental sound loudness, speed speed, environmental sound loudness In this case, the control unit 7 outputs that the sound effect is “high” regardless of whether the driver is a driver or a passenger. A signal is generated and output to the output unit 4.

  In the above case, the sound effect is “high” for both the driver and the occupant. This is because it is considered that the sound effect cannot be heard when the sound inside the vehicle is loud. Therefore, when the control unit 7 compares the threshold value 70 with the vehicle information 50 and determines that the environmental sound is “high”, the control sound 7 sets the sound effect to “high”.

  As mentioned above, although some embodiment and modification of this invention were demonstrated, these embodiment and modification are only examples, and do not limit the invention based on a claim. These novel embodiments and modifications can be implemented in various other forms, and various omissions, replacements, changes, and the like can be made without departing from the scope of the present invention.
