Abstract

PROBLEM TO BE SOLVED: To provide a vehicle interior trim part operating in a plurality of modes by operating a smaller number of touch sensors.SOLUTION: An operation switch includes a pair of touch sensors. A vehicle interior trim part operates in a first mode if operation time of the other touch sensor out of the paired touch sensors is equal to or longer than first threshold time ΔT(FIG. 4(a)) on condition that the other touch sensor detects contact/approach of an input medium after one of the paired touch sensors detects the contact/approach of an input medium. If the operation time of the other touch sensor is shorter than the first threshold ΔT(FIG. 4(b)), the vehicle interior trim part operates in a second mode. That is, the operating mode of the vehicle interior trim part can be switched to another only by changing the operation time of the other touch sensor. It is thereby possible for the vehicle interior trim part to operate in a plurality of modes by operating a smaller number of touch sensors.

Description

  The present invention relates to a vehicle interior product, and more particularly, to a vehicle interior product provided with an actuator and an operation switch for operating the vehicle interior product.

  Many interior items are provided in the vehicle, and many of these interior items are activated by operating an operation switch. Specifically, for example, there is a so-called power seat including an actuator that operates at least a part of a seat provided in a vehicle in a predetermined direction and an operation switch for operating the actuator. In recent years, in order to improve the operability of a power seat, development of a power seat employing a touch sensor as an operation switch has been promoted as described in the following patent document.

JP 2011-201379 A

  As described in the above patent document, the operability is improved by adopting a touch sensor as the operation switch. However, some interior products that operate by operating the operation switch operate in a plurality of modes, and a number of touch sensors corresponding to the operation mode may be required for one interior product. In such a case, there are problems such as an increase in cost and a space for arranging a plurality of touch sensors. This invention is made | formed in view of such a situation, and makes it a subject to provide the interior goods for vehicles which operate | move in a some aspect by operation of a small number of touch sensors.

  In order to solve the above-described problem, an interior product for a vehicle according to claim 1 of the present application includes an actuator for operating the interior product of the vehicle, an operation switch for operating the actuator, and an operation of the operation switch. And a control device that controls the operation of the actuator. The operation switch includes a pair of touch sensors that detect contact / approach of an input medium, and the control device includes an input device. On the condition that the contact / approach of the input medium is detected by the other touch sensor after the contact / approach of the medium is detected by one touch sensor of the pair of touch sensors, the other touch sensor The operation of the actuator is controlled so that the vehicle interior product operates in the first mode when the operation time is equal to or longer than the first threshold time, When the operation time of the other touch sensor is less than the first threshold time, the operation of the actuator is controlled so that the vehicle interior product operates in a second mode different from the first mode. It is characterized by that.

  Further, in the vehicle interior product according to claim 2, in the vehicle interior product according to claim 1, the operation time of the other touch sensor is greater than or equal to a second threshold time and the first threshold is exceeded by the control device. When it is less than the time, the operation of the actuator is controlled so that the vehicle interior product operates in the second mode.

  Further, in the vehicle interior product according to claim 3, in the vehicle interior product according to claim 1 or 2, the first aspect may be configured while the other touch sensor is operated. The vehicle interior is an aspect in which the vehicle interior is operated, and the second aspect is an aspect in which the vehicle interior is operated for a set time or a set distance.

  In the vehicle interior article according to claim 1, the operation switch is constituted by a pair of touch sensors. Then, after the touch / approach of the input medium is detected by one touch sensor of the pair of touch sensors, the touch of the other input sensor is detected on the condition that the touch / approach of the input medium is detected by the other touch sensor. When the operation time of the sensor is equal to or longer than the first threshold time, the vehicle interior product operates in the first mode. On the other hand, when the operation time of the other touch sensor is less than the first threshold time, the vehicle interior product operates in the second mode.

  Specifically, when the first threshold time is set to a relatively short time, for example, about 0.3 seconds to 0.8 seconds, the user moves an input medium such as a finger from one sensor to the other sensor. By moving the sensor toward the other side and passing the vicinity of the other sensor at an appropriate speed, the operation time of the other sensor becomes less than the first threshold time. As a result, the vehicle interior article operates in the second mode. On the other hand, when the user moves the input medium from one sensor toward the other sensor and stops it in the vicinity of the other sensor, the operation time of the other sensor is equal to or longer than the first threshold time. As a result, the vehicle interior article operates in the first mode. In this way, it is possible to switch the operation mode of the vehicle interior by simply changing the operation time of the other touch sensor. Thereby, it is possible to reduce the number of touch sensors for controlling the operation of the vehicle interior product, and it is possible to reduce the arrangement space and cost of the touch sensors.

  Further, in the vehicle interior product according to claim 2, when the operation time of the other touch sensor is not less than the second threshold time and less than the first threshold time, the vehicle interior product operates in the second mode. To do. Specifically, when the second threshold time is set to an extremely short time, for example, about 0.05 seconds to 0.2 seconds, the user unexpectedly passes the input medium near the other touch sensor. Even so, the operation time of the other touch sensor is less than the second threshold time. Thereby, it becomes possible to operate the interior goods for vehicles only at the time of a user's intentional operation, and it becomes possible to prevent erroneous operation.

  In the vehicle interior product according to claim 3, the first mode is a mode in which the vehicle interior product operates while the other touch sensor is operated, and the second mode is used for the vehicle. This is a mode in which the interior product operates for a set time or set distance. Specifically, for example, when the vehicle interior is a seat and the operation switch is a switch that slides the seat back and forth, the input medium is moved from one touch sensor toward the other touch sensor. By stopping in the vicinity of the other touch sensor, the sheet can be slid by an arbitrary distance. Further, by moving the input medium from one touch sensor toward the other touch sensor and passing the vicinity of the other touch sensor, the sheet can be slid by a set distance or a set time.

It is a perspective view which shows the vehicle seat of an Example. It is sectional drawing in the AA line shown in FIG. It is a block diagram which shows the control apparatus with which the vehicle seat shown in FIG. 1 is provided. It is a chart which shows the relationship between the detected value of a pair of touch sensor of an Example, and the drive state of an electromagnetic motor. 10 is a chart showing a relationship between detection values of a pair of touch sensors according to Modification 1 and a driving state of an electromagnetic motor. 10 is a chart showing a relationship between a detection value of a pair of touch sensors according to Modification 2 and a driving state of an electromagnetic motor.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as modes for carrying out the present invention.

<Configuration of vehicle seat>
FIG. 1 shows a vehicle seat 10 according to an embodiment of the present invention. The vehicle seat 10 is a driver seat disposed on the right side of the vehicle. The vehicle seat 10 includes a seat cushion 12 that supports the driver's buttocks, a seat back 14 that supports the driver's back, and a headrest 16 that is provided at the upper end of the seat back 14 and supports the driver's head. The pair of side shields 18 that cover both side surfaces of the seat cushion 12 are configured. The vehicle seat 10 is a so-called power seat capable of adjusting various seating postures electrically, and an operation switch 20 for adjusting the position of the vehicle seat 10 in the front-rear direction is provided with a seat cushion. 12 is provided on the left side surface.

  A slide mechanism 30 is employed as a mechanism for changing the position of the vehicle seat 10 in the front-rear direction. The slide mechanism 30 includes a lower rail 32 that is fixed to the vehicle floor, an upper rail 34 that is slidable with respect to the lower rail 32, and an electromagnetic motor that relatively moves the lower rail 32 and the upper rail 34 (see FIG. 3). ) 36, and the vehicle seat 10 can be slid in the front-rear direction by the operation of the electromagnetic motor 36.

  The operation switch 20 for sliding the vehicle seat 10 in the front-rear direction is composed of a pair of touch sensors 50, 52, and the pair of touch sensors 50, 52 are arranged on the left side surface of the seat cushion 12. It is provided so that it may line up in the front-back direction. Since the touch sensors 50 and 52 have the same structure, the touch sensor 50 will be described as a representative.

  As shown in FIG. 2, which is a cross-sectional view taken along the line AA in FIG. 1, the touch sensor 50 includes a conductive cloth 54, and the conductive cloth 54 covers the seat pad 56 and the seat pad 56 of the seat cushion 12. It is inserted between the seat cover 58. The conductive cloth 54 is obtained by sewing a conductive thread (see FIG. 3) 60 that can be energized to a non-conductive cloth, and has conductivity by the conductive thread 60 that can be energized. As a method of sewing the conductive thread 60, various sewing methods such as main stitching, staggered stitching, wave stitching, and single ring stitching can be employed. In the conductive cloth 54, the conductive thread 60 is not sewn by the main sewing. It is sewn on a conductive cloth. Specifically, the conductive thread 60 is used as the upper thread of the sewing machine that can be sewn, and the normal sewing thread (not shown) is used as the lower thread, with respect to the non-conductive base fabric (not shown). Perform the main sewing. Thereby, the conductive cloth 54 is sewn.

  The conductive yarn 60 may be anything that can be energized, such as metal, alloy wire, carbon fiber filament, non-conductive wire plated with metal, alloy, etc., metal, It is possible to employ various types such as those in which an alloy wire and a non-conductive wire are twisted together. Moreover, as a base fabric, what is necessary is just a normal cloth material, and various things, such as a woven fabric, a knitted fabric, and a nonwoven fabric, are employable.

  The conductive cloth 54 having the above-described structure is disposed between the seat pad 56 and the seat cover 58 with the surface of the base cloth to which the conductive yarn 60 is sewn in contact with the seat cover 58. Yes. When an input medium such as a user's finger approaches the side where the conductive cloth 54 is disposed, the approach of the input medium can be detected by the conductive cloth 54. Specifically, the capacitance of the conductive yarn 60 changes due to the approach of the input medium to the place where the conductive cloth 54 is disposed, and the approach of the input medium is detected by the change in the capacitance. Yes. That is, the conductive cloth 54 functions as a capacitive touch sensor.

  The vehicle seat 10 includes a control device 70 as shown in FIG. The control device 70 includes a controller 72 mainly composed of a computer having a CPU, ROM, RAM, and the like, and a drive circuit 74 for the electromagnetic motor 36. An electromagnetic motor 36 is connected to the controller 72 via a drive circuit 74 so that the operation of the slide mechanism 30 can be controlled. In addition, the conductive yarn 60 of the touch sensors 50 and 52 is connected to the controller 72, and a change in the capacitance of the conductive yarn 60 is input to the controller 72. Specifically, an ON signal is input when the approach of the input medium is detected due to a change in the capacitance of the conductive yarn 60, and an OFF signal is input when the separation of the input medium is detected. Is done.

<Operation of slide mechanism>
In the vehicle seat 10, the seated person operates the pair of touch sensors 50 and 52 to control the operation of the slide mechanism 30. A specific operation method will be described below. In order to distinguish the pair of touch sensors 50 and 52, the touch sensor 50 disposed on the front side of the vehicle is referred to as a first touch sensor 50, and the touch sensor 52 disposed on the rear side of the vehicle is referred to as the first touch sensor 52. Sometimes referred to as a two-touch sensor 52.

  For example, when the vehicle seat 10 is slid rearward, the seated person moves the left hand from the front to the rear along the left side surface of the seat cushion 12. As a result, the left hand of the seated person first approaches the first touch sensor 50, and the detection value by the first touch sensor 50 is input to the controller 72 as shown in FIG. That is, an ON signal from the first touch sensor 50 is input to the controller 72. When the seated person moves the left hand further rearward, the seated person's left hand moves away from the first touch sensor 50 and approaches the second touch sensor 52. As a result, as shown in FIG. 4A, an OFF signal from the first touch sensor 50 and an ON signal from the second touch sensor 52 are input to the controller 72.

If the time t ₂ when the ON signal is input by the second touch sensor 52 has not elapsed from the time t ₁ at which the OFF signal is input by the first touch sensor 50 a predetermined time or more, i.e., the seat occupant to the left, The condition for sliding the vehicle seat 10 is satisfied when the second touch sensor 52 is approached within a predetermined time after being separated from the first touch sensor 50.

Next, it is determined whether or not the ON signal input by the second touch sensor 52 continues for the first set time ΔT ₁ . That is, the operation time of the second touch sensor 52 by the seat occupant, or is first set time [Delta] T ₁ or more is determined. When the operation time of the second touch sensor 52 is first set time [Delta] T ₁ or drives the electromagnetic motor 36, the vehicle seat 10 slides towards the rear. When the seated person moves the left hand away from the second touch sensor 52, the electromagnetic motor 36 stops and the sliding of the vehicle seat 10 also stops. In other words, the time t ₂ when the ON signal is input by the second touch sensor 52 until the [Delta] T ₁ first set time exceeds the time t ₃ when the sum, the seat occupant by operating the second touch sensor 52, a vehicle The seat 10 slides backward, and the vehicle seat 10 continues to slide backward while the seated person operates the second touch sensor 52. Thus, after operating the first touch sensor 50, a second touch sensor 52 by operating the first set time [Delta] T ₁ or more, the vehicle seat 10 any distance, and it can be slid rearward .

On the other hand, as shown in FIG. 4 (b), the input of the ON signal by the second touch sensor 52, if the first set is not in time [Delta] T ₁ continues, that is, the operation time of the second touch sensor 52 according to the seated person first when setting the time ΔT less than ₁ drives the electromagnetic motor 36, the vehicle seat 10 slides to the rear end. Incidentally, the first set time ΔT ₁ is set to a relatively short time, for example, about 0.3 seconds to 0.8 seconds, and the seated person stops the left hand at the side of the second touch sensor 52. Instead, the operation time of the second touch sensor 52 is less than the first set time ΔT ₁ by passing the side of the second touch sensor 52 at an appropriate speed. That is, when the seated person moves the left hand from the front to the rear and passes the side of the second touch sensor 52 at an appropriate speed, the electromagnetic motor 36 is driven and the vehicle seat 10 is moved to the rear. Slide to the end. Incidentally, as shown in FIG. 4B, the electromagnetic motor 36 starts to be driven at the timing when the OFF signal from the second touch sensor 52 is inputted, that is, when the operation of the second touch sensor 52 is released. However, the driving of the electromagnetic motor 36 may be started from the timing when the first set time ΔT ₁ has elapsed, that is, from the time t ₃ .

Incidentally, when the operation time of the second touch sensor 52 by the seat occupant be the first less than the set time [Delta] T _1, which is smaller than the second set time [Delta] T ₂ that is set to less than [Delta] T ₁ first set time period Does not drive the electromagnetic motor 36. That is, when the operation time of the second touch sensor 52 is not less than the second set time ΔT _{2 and} less than the first set time ΔT ₁ , the vehicle seat 10 slides to the rear end. The second set time ΔT ₂ is set to an extremely short time, for example, about 0.05 to 0.2 seconds, and the occupant passes the side of the second touch sensor 52 at a suddenly high speed. when obtained by the operating time of the second touch sensor 52 becomes smaller than the second set time [Delta] T _2. As a result, the vehicle seat 10 can be slid only during the intended operation of the seated person, and erroneous operation can be prevented.

  When the vehicle seat 10 is slid forward, the seat occupant moves the left hand from the rear toward the front along the left side surface of the seat cushion 12. As a result, the ON signal from the second touch sensor 52 is input to the controller 72. Then, when the seated person moves the left hand further forward, an OFF signal from the second touch sensor 52 is input to the controller 72 and an ON signal from the first touch sensor 50 is input. At this time, when the time when the ON signal is input by the first touch sensor 50 does not elapse for a predetermined time from the time when the OFF signal is input by the second touch sensor 52, the vehicle seat 10 is slid. The conditions are satisfied.

Next, if the operation time of the first touch sensor 50, or is first set time [Delta] T ₁ or more is determined, the operation time of the first touch sensor 50 is first set time [Delta] T ₁ or more, i.e., the left hand are moved from the rear toward the front, the first set time [Delta] T ₁ or more, when stopped at the side of the first touch sensor 50, the vehicle seat 10 slides forwardly, the seated person first While operating the touch sensor 50, the vehicle seat 10 continues to slide forward. On the other hand, when the operation time of the first touch sensor 50 is not less than the second set time ΔT _{2 and} less than the first set time ΔT ₁ , that is, the left hand is moved from the rear toward the front, When the side of the touch sensor 50 is passed, the vehicle seat 10 slides to the front end.

  Thus, in the vehicle seat 10, the pair of touch sensors 50, 52 are arranged side by side in the front-rear direction of the vehicle, that is, in the sliding direction of the vehicle seat 10. The sliding direction of the vehicle seat 10 is determined by the operation order of 52. Specifically, when the seated person moves the left hand from the front toward the rear and the second touch sensor 52 is operated after the first touch sensor 50 is operated, the vehicle seat 10 is moved backward. Slide towards you. On the other hand, when the seated person moves the left hand from the rear to the front and the first touch sensor 50 is operated after the second touch sensor 52 is operated, the vehicle seat 10 slides forward. To do. As a result, the seated person can intuitively operate the vehicle seat 10.

Further, the operation mode of the slide mechanism 30 differs depending on the operation time of the touch sensors 50 and 52 located on the downstream side. Specifically, when the operation time of the touch sensors 50 and 52 positioned on the downstream side is equal to or longer than the first set time ΔT ₁ , the vehicle while the touch sensors 50 and 52 positioned on the downstream side are being operated. The sheet 10 slides. In other words, the vehicle seat 10 slides an arbitrary distance by the operation of the seated person. On the other hand, when the operation time of the touch sensors 50 and 52 located on the downstream side is not less than the second set time ΔT _{2 and} less than the first set time ΔT ₁ , the vehicle seat 10 slides to the front end or the rear end. To do. That is, the vehicle seat 10 moves to a preset location. As described above, in the vehicle seat 10, the first mode in which the vehicle seat 10 is slid by an arbitrary distance and the vehicle seat 10 is slid by a set distance only by changing the operation time of the touch sensors 50 and 52. It is possible to switch between these modes. Thereby, the number of switches for controlling the operation of the slide mechanism 30 can be reduced.

Incidentally, in the said Example, the vehicle seat 10 is an example of the interior goods for vehicles. The operation switch 20 is an example of an operation switch. The electromagnetic motor 36 is an example of an actuator. The touch sensors 50 and 52 are examples of touch sensors. The control device 70 is an example of a control device. The first set time ΔT ₁ is an example of a first threshold time. The second set time ΔT ₂ is an example of a second threshold time.

In addition, this invention is not limited to the said Example, It can implement in the various aspect which gave various change and improvement based on the knowledge of those skilled in the art. Specifically, for example, in the above embodiment, the first set time ΔT ₁ for switching the operation mode of the slide mechanism 30 is the time when the ON signal from the second touch sensor 52 is input as shown in FIG. Although t ₂ is the time as a starting point, it is possible to set the starting point at any time. Specifically, for example, as shown in FIG. 5, the third set time ΔT ₃ may be set starting from the time t ₁ when the OFF signal from the first touch sensor 50 is input. Further, as shown in FIG. 6, the fourth set time ΔT ₄ may be set starting from the time t ₀ when the ON signal from the first touch sensor 50 is input. In the vehicle seat in which the third set time ΔT ₃ or the fourth set time ΔT ₄ is set as the first threshold time, the second touch sensor exceeds the third set time ΔT ₃ or the fourth set time ΔT _4. When 52 is operated (FIGS. 5A and 6A), the vehicle seat 10 slides an arbitrary distance according to the operation of the seated person. On the other hand, if the operation of the second touch sensor 52 is canceled before the third set time ΔT ₃ or the fourth set time ΔT _{4 has} elapsed (FIG. 5B, FIG. 6B), The sheet 10 slides to the front end or the rear end.

  Moreover, in the said Example, although the slide mechanism 30 is employ | adopted as a mechanism for operating the vehicle seat 10, other types of mechanisms can be employed. Specifically, a reclining mechanism that can change the inclination angle of the seat back with respect to the seat cushion, a lumbar support mechanism that can adjust the holding state of the seated person's waist, a lifter mechanism that can adjust the height of the vehicle seat, and a seat cushion Front tilt mechanism that can change the front tilt amount of the seat, the length of the seat cushion in the front-rear direction, the folding angle of the seat back, the folding angle of the side support, the tilt angle of the headrest, etc. It is possible to employ a mechanism that can adjust the temperature of the sheet.

Further, the mechanism operated by the operation switch 20 is not limited to one type of mechanism, and a plurality of types of mechanisms may be operated by operating the operation switch 20. Specifically, for example, the seated person moves the left hand from the rear toward the front, when the operation time of the first touch sensor 50 is first less than the set time [Delta] T _1, the vehicle seat 10, slide mechanism The seat back 14 may be slid to the front end by 30 and the seat back 14 may be inclined forward most by the reclining mechanism. Thus, the operation switch 20 can perform an operation for securing a moving space when getting on and off the rear seat of the vehicle and an operation for sliding the slide mechanism 30 at an arbitrary distance.

  Moreover, in the said Example, although the vehicle seat 10 is employ | adopted as a vehicle interior goods operated with the operation switch 20, various vehicle interior goods can be employ | adopted. Specifically, a window, sunroof, sunshade, door lock mechanism, etc. is adopted, and the above technology can be applied to an operation switch for opening / closing the window, sunroof, sunshade, etc., door lock, etc. Is possible. Specifically, when the operation time of the touch sensors 50 and 52 is equal to or longer than the first threshold time, the opening / closing operation of the window or the like is performed for an arbitrary time according to the operation time of the touch sensors 50 and 52, When the operation time of 50 and 52 is less than the first threshold time, an opening / closing operation of a window or the like is performed for a set time. Further, when the operation time of the touch sensors 50 and 52 is equal to or longer than the first threshold time, the sunroof is slid, and when the operation time of the touch sensors 50 and 52 is less than the first threshold time, the sunroof is tilted. Let Furthermore, when the operation time of the touch sensors 50 and 52 is equal to or longer than the first threshold time, the window is opened and closed, and when the operation time of the touch sensors 50 and 52 is less than the first threshold time. Performs the switching operation of locking / releasing of the door locking mechanism.

  Furthermore, for example, the above technique can be applied to operation switches such as an air conditioner, a room lamp, and an audio device. Specifically, when the operation time of the touch sensors 50 and 52 is less than the first threshold time, the power ON / OFF switching operation of the air conditioner or the like is performed, and the operation time of the touch sensors 50 and 52 is the first. If it is longer than one threshold time, operations such as air volume adjustment, temperature adjustment, and volume adjustment are performed according to the operation time of the touch sensors 50 and 52.

  In addition, the above technique can be applied to operation switches of vehicles, specifically, interior products of various vehicles such as airplanes and trains.

  In the above embodiment, the conductive cloth 54 in which the conductive thread 60 is sewn on the cloth is used as the touch sensor. However, a general touch sensor, specifically, a top cover, a substrate, and an electrode are used. It is possible to employ an electrode configured to detect contact or approach of an input medium depending on a change in capacitance. Furthermore, it is possible to employ a touch sensor of a type different from the capacitive type touch sensor. Specifically, various types of touch sensors such as a surface acoustic wave method, a resistance film method, an electromagnetic induction method, an infrared method, and the like can be employed.
