Japanese Unexamined Patent Publication No. 2006-161491

By the way, in the power slide door device as described above, the inside door handle is fixedly arranged at a position near the front end of the slide door inside the vehicle. Therefore, when the sliding door is fully closed, the distance from the occupant seated on the side seat of the door opening to the inside door handle tends to be long. That is, in the power slide door device as described above, depending on the open / closed state of the slide door, it may be difficult for the occupant seated on the seat on the side of the door opening to operate the inside door handle.

An object of the present invention is to provide a vehicle operation detection device in which an occupant can easily input an operation for opening and closing the slide door regardless of the open / closed state of the slide door, and a slide door device including the vehicle operation detection device. Is.

Hereinafter, means for solving the above problems and their actions and effects will be described.
The vehicle operation detection device that solves the above problems is a long vehicle operation detection device attached to the sliding door, and includes a first detection unit and a second detection unit that detect operation inputs, and the first detection unit. Outputs an open operation command signal for opening the slide door based on the detection result of the above, and outputs a close operation command signal for closing the slide door based on the detection result of the second detection unit. A control unit is provided, the first detection unit is arranged at a position near the first end in the longitudinal direction of the vehicle operation detection device, and the second detection unit is arranged with the first end in the longitudinal direction. Is arranged at a position near the second end on the opposite side, and each of the first detection unit and the second detection unit has an electrode having an electrode whose capacitance increases as the distance from the detection target decreases. The capacitance sensor has a plurality of the electrodes arranged so as to be arranged in the longitudinal direction, and the control unit is the electrode whose capacitance changes in the plurality of electrodes of the first detection unit. Is switched in a specific order, the open operation command signal is output, and in the plurality of electrodes of the second detection unit, the closing operation is performed when the electrodes whose capacitance changes are switched in a specific order. Output a command signal .

It is assumed that the vehicle operation detection device is attached to the slide door so that the first end and the second end of the vehicle operation detection device are on the rear side and the front side of the vehicle, respectively. In this case, if the second detection unit is arranged at a position closer to the front end of the slide door, the first detection unit is arranged at a position behind the front end of the slide door. That is, when the second detection unit, which is configured to detect the operation input for closing the slide door, is arranged at a position near the front end of the slide door, the first detection unit for detecting the operation input for opening the slide door is the slide door. It is placed behind the front end of.

Therefore, when the sliding door is fully closed, the second detection unit is arranged at a position near the front end of the door opening provided on the side surface of the vehicle, and the first detection unit is behind the second detection unit. Placed in position. Further, when the sliding door is in the fully open state, the sliding door moves rearward with respect to the door opening as compared with the case where the sliding door is in the fully closed state. Therefore, when the slide door is in the fully open state, the first detection unit and the second detection unit are arranged at positions rearward of the door opening as compared with the case where the slide door is in the fully closed state.

Therefore, the distance from the occupant seated on the seat on the side of the door opening to the first detection unit when the sliding door is fully closed tends to be short. In addition, the distance from the occupant to the second detection unit when the slide door is fully open tends to be short. In this way, the occupant can easily input an operation for opening and closing the slide door to the vehicle operation detection device regardless of the open / closed state of the slide door.

According to the above configuration, the occupant can input the operation by bringing his / her hand close to or touching the first detection unit and the second detection unit. In other words, the occupant can input the operation without pulling or turning the inside door handle, for example. In this way, the burden of inputting the operation of the occupant is reduced.
For example, when an occupant seated in a seat leans against a sliding door, a part of the occupant's body may approach the first detection unit and the second detection unit. In this case, the control unit may output an open operation command signal and a closed operation command signal based on an operation input not intended by the occupant. However, in this case, since a part of the occupant's body approaches the plurality of electrodes constituting the first detection unit and the second detection unit at the same time, the capacitances of the plurality of electrodes are likely to change at the same time.
Therefore, in the above configuration, the control unit issues an open operation command signal and a closed operation command signal when the electrodes whose capacitance changes are switched in a specific order in the first detection unit and the second detection unit. Therefore, it is further suppressed that the sliding door is opened and closed based on an operation input not intended by the occupant.

In the vehicle operation detection device, when the capacitance of the electrode of the first detection unit is equal to or greater than a determination value set as a lower limit value for determining contact with the detection target, the control unit said. It is preferable to output the open operation command signal and output the closed operation command signal when the capacitance of the electrode of the second detection unit is equal to or greater than the determination value.

For example, if the distance between the occupant seated in the seat and the vehicle operation detection device provided on the sliding door is short, the occupant's body may approach the electrodes of the first detection unit and the second detection unit. .. In this case, the control unit may output an open operation command signal and a closed operation command signal based on an operation input not intended by the occupant.

In this regard, according to the above configuration, the control unit receives the open operation command signal and the opening operation command signal on condition that the capacitance of the electrode is equal to or greater than the determination value for determining the contact of the detection target (for example, the occupant's hand). Outputs a closing operation command signal. That is, the control unit outputs the open operation command signal and the closed operation command signal on condition that the operation input is performed with the occupant in contact with the detection device. As a result, it is suppressed that the sliding door is opened and closed based on an operation input not intended by the occupant.

In the vehicle operation detection device, when the control unit switches the electrodes whose capacitance changes in the direction from the second end to the first end in the plurality of electrodes of the first detection unit. When the electrodes that output the open operation command signal and whose capacitance changes in the direction from the first end to the second end of the plurality of electrodes of the second detection unit are switched, the closing is performed. It is preferable to output an operation command signal.

According to the above configuration, when the sliding door is opened, it is necessary to input an operation such as tracing a plurality of electrodes of the first detection unit in the moving direction of the sliding door to be opened. Further, when closing the sliding door, it is necessary to input an operation such as tracing a plurality of electrodes of the second detection unit in the moving direction of the sliding door that closes. Therefore, while suppressing the complexity of the operation input, it is possible to suppress the opening and closing operation of the slide door due to the operation input not intended by the occupant.

The vehicle operation detection device that solves the above problems is a long vehicle operation detection device attached to a sliding door, and includes a first detection unit and a second detection unit that detect an operation input, and the first detection unit. Outputs an open operation command signal for opening the slide door based on the detection result of the above, and outputs a close operation command signal for closing the slide door based on the detection result of the second detection unit. A control unit is provided, the first detection unit is arranged at a position near the first end in the longitudinal direction of the vehicle operation detection device, and the second detection unit is arranged with the first end in the longitudinal direction. Is arranged at a position near the second end on the opposite side, and when the side on which the first detection unit and the second detection unit are provided is the inside, the operation is on the outside opposite to the inside. a third detection unit for detecting an input, the first detector, the second respective detector and the third detector includes a static having an electrode distance of the detection target becomes higher capacitance as shorter It is an electric capacity sensor, and the control unit outputs the open operation command signal according to the capacitance of the electrode of the first detection unit, and outputs the open operation command signal according to the capacitance of the electrode of the second detection unit. outputting the closing command signal, you output the opening operation instruction signal and the closing command signal in response to the capacitance of the electrode of the third detecting unit.
It is assumed that the vehicle operation detection device is attached to the slide door so that the first end and the second end of the vehicle operation detection device are on the rear side and the front side of the vehicle, respectively. In this case, if the second detection unit is arranged at a position closer to the front end of the slide door, the first detection unit is arranged at a position behind the front end of the slide door. That is, when the second detection unit, which is configured to detect the operation input for closing the slide door, is arranged at a position near the front end of the slide door, the first detection unit for detecting the operation input for opening the slide door is the slide door. It is placed behind the front end of.
Therefore, when the sliding door is fully closed, the second detection unit is arranged at a position near the front end of the door opening provided on the side surface of the vehicle, and the first detection unit is behind the second detection unit. Placed in position. Further, when the sliding door is in the fully open state, the sliding door moves rearward with respect to the door opening as compared with the case where the sliding door is in the fully closed state. Therefore, when the slide door is in the fully open state, the first detection unit and the second detection unit are arranged at positions rearward of the door opening as compared with the case where the slide door is in the fully closed state.
Therefore, the distance from the occupant seated on the seat on the side of the door opening to the first detection unit when the sliding door is fully closed tends to be short. In addition, the distance from the occupant to the second detection unit when the slide door is fully open tends to be short. In this way, the occupant can easily input an operation for opening and closing the slide door to the vehicle operation detection device regardless of the open / closed state of the slide door.
According to the above configuration, the occupant can input the operation by bringing his / her hand close to or touching the first detection unit and the second detection unit. In other words, the occupant can input the operation without pulling or turning the inside door handle, for example. In this way, the burden of inputting the operation of the occupant is reduced.

It is assumed that the vehicle operation detection device is attached to the slide door so that the inside of the vehicle operation detection device is the inside of the vehicle and the outside of the vehicle operation detection device is the outside of the vehicle. According to this, the operation input from the inside of the vehicle can be detected by the first detection unit and the second detection unit, and the operation input from the outside of the vehicle can be detected by the third detection unit. That is, the sliding door can be opened and closed based on the operation input from inside and outside the vehicle.

In the vehicle operation detection device, the control unit outputs the open operation command signal when the capacitance of the electrode of the first detection unit is equal to or higher than a preset first determination value, and the second When the capacitance of the electrode of the detection unit is equal to or greater than the first determination value, the closing operation command signal is output, and the capacitance of the electrode of the third detection unit is smaller than the first determination value. It is preferable to output the open operation command signal and the closed operation command signal when the determination value is 2 or more.

When an occupant is seated on the seat on the side of the sliding door, the capacitance of the electrodes of the first detection unit and the second detection unit is due to the presence of the occupant in the vicinity of the first detection unit and the second detection unit. There are many opportunities for it to be high. That is, the first detection unit and the second detection unit are more likely to detect an operation input not intended by the occupant than the third detection unit.

Therefore, in the above configuration, the first determination value used for determination when outputting the open operation command signal and the closed operation command signal is the third, according to the capacitance of the electrodes of the first detection unit and the second detection unit. Depending on the capacitance of the electrode of the detection unit, it is made larger than the second determination value used for the determination when the open operation command signal and the close operation command signal are output. Therefore, it is possible to prevent the sliding door from being opened and closed based on an unintended operation input of the occupant from the inside of the vehicle.

The slide door device for solving the above problems includes the above-mentioned vehicle operation detection device and the slide door, and the vehicle operation detection device has the first end located behind the vehicle than the second end. It is attached to the slide door so that the position and the longitudinal direction are the moving directions of the slide door, and the distance between the first detection unit and the second detection unit in the longitudinal direction is the above. It is a distance according to the amount of movement when the sliding door moves between the fully open state and the fully closed state.

According to the slide door device having the above configuration, the position of the first detection unit when the slide door is fully closed and the position of the second detection unit when the slide door is fully open are set to the same position. Can be placed. Therefore, it becomes easier for the occupant to input an operation for opening and closing the slide door to the operation detection device for the vehicle.

According to the vehicle operation detection device, it becomes easy for the occupant to input an operation for opening and closing the slide door regardless of the open / closed state of the slide door.

Further, a sliding door 3 that opens and closes the door opening 2a as the vehicle 1 moves in the front-rear direction is mounted on the side portion of the body 2. The sliding door 3 is in a fully open state in which the door opening 2a is opened by moving to the rear of the vehicle 1, and is in a fully closed state in which the door opening 2a is closed by moving to the front of the vehicle 1.

The sliding door 3 has a substantially bag-shaped door panel 4 constituting the lower portion thereof, and also has a window glass 5 that advances and retreats in the vertical direction from the door panel 4. A door lock 6 for locking and unlocking the sliding door 3 in the closed state is installed on the door panel 4.

In the sliding door 3, for example, in the door panel 4, the door driving unit 11 is installed. The door drive unit 11 is mainly composed of an electric drive source such as an electric motor, and opens and closes and drives the slide door 3 by being mechanically linked with the body 2 via an appropriate door drive mechanism. Thus, in this embodiment, an example of a so-called power slide door device is configured including the door drive unit 11.

Further, the sliding door 3 is provided with a door lock driving unit 12 adjacent to the door lock 6, for example. The door lock drive unit 12 is mainly composed of an electric drive source such as an electric motor, and is mechanically linked with the door lock 6 via an appropriate lock drive mechanism to lock and unlock the door lock 6. do.

Both the door drive unit 11 and the door lock drive unit 12 are electrically connected to, for example, a door ECU 10 composed of a microcomputer, and are individually driven and controlled by the door ECU 10. The door ECU 10 drives the door drive unit 11 to open the slide door 3 when an open operation command signal is input from the electronic key (portable device) and the detection device 20 described later. Further, the door ECU 10 drives the door drive unit 11 to close the slide door 3 when a closing operation command signal is input from the electronic key (portable device) and the detection device 20.

As shown in FIG. 2, a belt molding 8 for draining water, which is in sliding contact with the outer surface of the window glass 5 that advances and retreats in the vertical direction, is attached to the upper end of the door panel 4. Further, above the door panel 4, a detection device 20 that detects a user's operation input from inside and outside the vehicle 1 is installed inside the vehicle 1 rather than the window glass 5.

In the present embodiment, an example of the sliding door device 50 is configured including the sliding door 3, the door lock 6, the door ECU 10, the door driving unit 11, the door lock driving unit 12, and the detection device 20.

Next, the detection device 20 will be described with reference to FIGS. 3 to 5. In the present embodiment, the operation input to be detected by the detection device 20 includes an operation input performed by a user (occupant) inside the vehicle 1 and an operation input performed by a user outside the vehicle 1.

As shown in FIGS. 3 and 4, the detection device 20 includes a first detection unit 21 having a first electrode 31, a second electrode 32, and a first detection circuit 41, and a third electrode 33, a fourth electrode 34, and a first detection circuit 41. It includes a second detection unit 22 having two detection circuits 42, and a third detection unit 23 having a fifth electrode 35, a sixth electrode 36, a seventh electrode 37, and a third detection circuit 43. Further, the detection device 20 includes a control circuit 24 connected to the first detection circuit 41, the second detection circuit 42, and the third detection circuit 43, and a housing 26 for accommodating the constituent members of the detection device 20. There is.

As shown in FIG. 3, the detection device 20 (housing 26) has a long shape and a substantially rectangular parallelepiped shape. As shown in FIG. 1, the length of the detection device 20 (housing 26) in the longitudinal direction X is shorter than the length of the window glass 5 of the slide door 3 in the front-rear direction. Further, in the longitudinal direction X of the detection device 20, the distance between the first detection unit 21 and the second detection unit 22 is the amount of movement when the slide door 3 moves between the fully closed state and the fully open state. It is the corresponding distance. Specifically, in the longitudinal direction X of the detection device 20, the distance between the center of the first detection unit 21 and the center of the second detection unit 22 is set between the fully closed state and the fully open state of the slide door 3. It may be the amount of movement when moving. In the following description, one end of the detection device 20 will be referred to as "first end X1", and the other end opposite to the first end X1 will be referred to as "second end X2".

As shown in FIG. 3, the first detection unit 21 is arranged near the first end X1 in the longitudinal direction X of the detection device 20, and the second detection unit 22 is the second end X2 in the longitudinal direction X of the detection device 20. It is located nearby. In other words, the first detection unit 21 is arranged at a position closer to the first end X1 than the second end X2 in the longitudinal direction X of the detection device 20, and the second detection unit 22 is located in the longitudinal direction X of the detection device 20. It is arranged at a position closer to the second end X2 than the first end X1. The third detection unit 23 is arranged at the center of the detection device 20 in the longitudinal direction X. Further, the first detection unit 21 and the second detection unit 22 are arranged inside the detection device 20, and the third detection unit is arranged outside the detection device 20. In the present embodiment, the first detection unit 21, the second detection unit 22, and the third detection unit 23 constitute a capacitance sensor.

In the first detection unit 21, the second detection unit 22, and the third detection unit 23, the electrodes 31 to 37 have a substantially rectangular plate shape. The electrodes 31 to 37 are preferably formed in a size suitable for the user's hand. The first electrode 31 and the second electrode 32 of the first detection unit 21, the third electrode 33 and the fourth electrode 34 of the second detection unit 22, and the fifth electrode 35, the sixth electrode 36, and the seventh electrode of the third detection unit 23. The electrodes 37 are arranged so as to be aligned with each other in the longitudinal direction X of the detection device 20. The first electrode 31, the second electrode 32, the third electrode 33, and the fourth electrode 34 face the inside of the detection device 20 (lower side in FIG. 3), and the fifth electrode 35, the sixth electrode 36, and the seventh electrode 37 It faces the outside of the detection device 20 (upper side in FIG. 3).

The capacitance of the electrodes 31 to 37 increases as the distance from the detection target decreases. For example, in the case where the detection target is brought close to the portion where the electrodes 31 to 37 of the detection device 20 are provided and the case where the detection target is brought into contact with the same portion, the latter case is better than the former case. The distance between ~ 37 and the detection target becomes shorter. Therefore, the capacitance of the electrodes 31 to 37 is higher when the detection target is brought into contact with the portion of the detection device 20 than when the detection target is brought close to the portion where the electrodes 31 to 37 are provided. Become. In the present embodiment, the approach means a state in which the objects are not in contact with each other although the distance between the objects is relatively short.

As shown in FIG. 4, the first detection circuit 41 outputs an oscillation signal to the first electrode 31 and the second electrode 32 to generate a signal corresponding to the capacitance of the first electrode 31 and the second electrode 32. Output. The second detection circuit 42 outputs an oscillation signal to the third electrode 33 and the fourth electrode 34, thereby outputting a signal corresponding to the capacitance of the third electrode 33 and the fourth electrode 34. The third detection circuit 43 outputs an oscillation signal to the fifth electrode 35, the sixth electrode 36, and the seventh electrode 37, so that the third detection circuit 43 responds to the capacitances of the fifth electrode 35, the sixth electrode 36, and the seventh electrode 37. Output the signal. Then, the first detection circuit 41, the second detection circuit 42, and the third detection circuit 43 output the signals output from the electrodes 31 to 37 to the control circuit 24 after A / D (analog / digital) conversion, respectively. ..

The control circuit 24 executes various arithmetic processes based on the signals output from the first detection circuit 41, the second detection circuit 42, and the third detection circuit 43, and outputs a control signal according to the result of the arithmetic processing to the door ECU 10. Output to. Specifically, the control circuit 24 outputs an open operation command signal to the door ECU 10 based on the capacitances of the electrodes 31 to 37 of the first detection unit 21, the second detection unit 22, and the third detection unit 23. A closing operation command signal is output to the door ECU 10. In this embodiment, the control circuit 24 corresponds to an example of a "control unit".

The detection device 20 is arranged on the slide door 3 so that the inside of the detection device 20 is the inside of the vehicle 1 and the outside of the detection device is the outside. Further, the detection device 20 is arranged on the slide door 3 so that the first end X1 is located behind the vehicle 1 and the longitudinal direction X is the moving direction of the slide door 3. Specifically, as shown in FIG. 1, the detection device 20 is arranged on the slide door 3 so that the second end X2 is aligned with the front end of the window glass. Therefore, in the detection device 20, the first detection unit 21 is arranged at a position closer to the center of the slide door 3 in the front-rear direction of the vehicle 1, and the second detection unit 22 is arranged at a position closer to the front end of the slide door 3. Will be done.

Next, the information detected by the detection device 20 and the determination content based on the information will be described in detail.
As described above, in the detection device 20, the first detection unit 21, the second detection unit 22, and the third detection unit 23 detect the operation input from the user. After that, in the detection device 20, the control circuit 24 determines whether or not there is an open operation input for opening the slide door 3 based on the detection results of the first detection unit 21 and the third detection unit 23, and the second Based on the detection results of the detection unit 22 and the third detection unit 23, it is determined whether or not there is a closing operation input for closing the slide door 3. That is, in the present embodiment, the first detection unit 21 is configured to detect the open operation input, the second detection unit 22 is configured to detect the closing operation input, and the third detection unit 23 is configured. Is a configuration for detecting an open operation input and a closed operation input. Then, in the detection device 20, the control circuit 24 outputs an open operation command signal to the door ECU 10 when it is determined that the open operation input has been performed, and when it is determined that the close operation input has been performed, the close operation command is issued. The signal is output to the door ECU 10.

Hereinafter, the open operation input, the close operation input, and the determination method of each input will be described in detail.
As shown by the solid arrow in FIG. 3, in the first detection unit 21, the opening operation input is from the first electrode 31 to the second electrode in a state where the user brings his / her hand close to or makes contact with the first detection unit 21. This is an operation of moving the hand toward 32. Further, in the third detection unit 23, the open operation input moves the hand from the fifth electrode 35 toward the seventh electrode 37 in a state where the user brings his / her hand close to or makes contact with the third detection unit 23. It is an operation. The open operation input is an operation in which the user swipes his / her hand toward the first detection unit 21 and the third detection unit 23 toward the rear of the vehicle 1 (hereinafter, also referred to as “rear swipe”). Further, in the present embodiment, the user's hand may be a part of the hand such as a fingertip, a palm, and the back of the hand, or may be the whole hand.

Further, as shown by the broken line arrow in FIG. 3, in the second detection unit 22, the closing operation input is input from the fourth electrode 34 to the second detection unit 22 with the user approaching or touching the second detection unit 22. This is an operation of moving the hand toward the three electrodes 33. Further, in the third detection unit 23, the closing operation input moves the hand from the seventh electrode 37 toward the fifth electrode 35 in a state where the hand is brought close to or in contact with the third detection unit 23. It is an operation. The closing operation input is an operation in which the user swipes his / her hand toward the front of the vehicle 1 with respect to the second detection unit 22 and the third detection unit 23 (hereinafter, also referred to as “front swipe”).

For example, as shown in FIG. 5A, when the user swipes backward on the first detection unit 21, the capacitances C1 and C2 of the first electrode 31 and the second electrode 32 increase or decrease in order. That is, at the second time t12 after the first time t11 when the capacitance C1 of the first electrode 31 becomes equal to or higher than the preset first determination value Cth1, the capacitance C2 of the second electrode 32 becomes The first determination value is Cth1 or higher.

Therefore, in the control circuit 24, has the first detection unit 21 performed a post-swipe on the first detection unit 21 based on the order of the electrodes 31 and 32 in which the capacitance is the first determination value Cth1 or more? Judge whether or not. Specifically, in the control circuit 24, in the first detection unit 21, after the capacitance of the first electrode 31 becomes the first determination value Cth1 or more, the capacitance of the second electrode 32 becomes the first determination value Cth1 or more. If, it is determined that the post-swipe has been performed on the first detection unit 21.

Similarly, in the control circuit 24, in the second detection unit 22, a front swipe is performed on the second detection unit 22 based on the order of the electrodes 33 and 34 whose capacitance is the first determination value Cth1 or more. Determine if it is. Specifically, in the control circuit 24, in the second detection unit 22, after the capacitance of the fourth electrode 34 becomes the first determination value Cth1 or more, the capacitance of the third electrode 33 becomes the first determination value Cth1 or more. If, it is determined that the front swipe has been performed on the second detection unit 22.

The first determination value Cth1 is a determination value set as a lower limit value for determining the contact of the user's hand as a detection target with the detection device 20 (housing 26). Therefore, when the user's hand is in contact with the detection device 20 (housing 26) and the operation input is performed to the first detection unit 21 and the second detection unit 22, the front swipe and the rear swipe are performed. Can be judged. In other words, when the operation input is performed to the first detection unit 21 and the second detection unit 22 with the user's hand close to the housing 26, it is not determined that the front swipe and the rear swipe have been performed. It has become.

Further, as shown in FIG. 5B, when the user swipes backward on the third detection unit 23, the capacitances C5, C6, of the fifth electrode 35, the sixth electrode 36, and the seventh electrode 37 C7 increases and decreases in order. That is, at the first time t21, the capacitance C5 of the fifth electrode 35 becomes equal to or higher than the preset second determination value Cth2. After that, at the second time t22 after the first time t21, the capacitance C6 of the sixth electrode 36 becomes the second determination value Cth2 or more. Then, at the third time t23 after the second time t22, the capacitance C7 of the seventh electrode 37 becomes the second determination value Cth2 or more.

Therefore, in the control circuit 24, has the third detection unit 23 performed a post-swipe on the third detection unit 23 based on the order of the electrodes 35 to 37 in which the capacitance is the second determination value Cth2 or more? Judge whether or not. Specifically, in the control circuit 24, when the electrodes 35 to 37 having a capacitance of the second determination value Cth2 or more are switched in the order of the fifth electrode 35, the sixth electrode 36, and the seventh electrode 37 in the third detection unit 23. , It is determined that the post-swipe has been performed on the third detection unit 23. Similarly, in the control circuit 24, in the third detection unit 23, when the electrodes 35 to 37 having a capacitance of the second determination value Cth2 or more are switched in the order of the seventh electrode 37, the sixth electrode 36, and the fifth electrode 35. , It is determined that the front swipe has been performed on the third detection unit 23.

The second determination value Cth2 is set to be less than the determination value preset as the lower limit value for determining the contact of the user's hand with the detection device 20 (housing 26). That is, the second determination value Cth2 is set to a value smaller than the first determination value Cth1. Therefore, in the third detection unit 23, not only when the operation input is performed to the third detection unit 23 with the user's hand in contact with the housing 26, but also the user's hand is brought close to the housing 26. Even when the operation input is performed to the third detection unit 23 in the state, it can be determined that the front swipe and the rear swipe have been performed.

By the way, in the detection device 20, the first detection unit 21 and the second detection unit 22 are provided at positions close to the user seated on the side seat of the door opening 2a. In this respect, the first detection unit 21 and the second detection unit 22 are more likely to detect an operation input not intended by the user than the third detection unit 23. Specifically, the first detection unit 21 and the second detection unit 22 detect an operation input due to an erroneous operation of a user sitting on a seat on the side of the door opening 2a, or accompany the user's leaning on the slide door 3. There is a possibility of detecting operation input. In this case, it is preferable that the detection device 20 does not determine that the rear swipe and the front swipe have been performed so as not to output the open operation command signal and the close operation command signal.

For example, when the user inputs an operation to the first detection unit 21 with the intention of opening the slide door 3, the capacitance of the first electrode 31 is the first determination value Cth1 during a certain period of time. After the above, the capacitance of the second electrode 32 becomes the first determination value Cth1 or more. In other words, when the period from when the capacitance of the first electrode 31 becomes the first determination value Cth1 or more to when the capacitance of the second electrode 32 becomes the first determination value Cth1 or more is extremely short, and the same. When the period is extremely long, it is highly possible that the first detection unit 21 has detected an operation input not intended by the user.

Therefore, in the control circuit 24, in the first detection unit 21, the first determination period (hereinafter, also referred to as “first determination period Tth1”) after the capacitance of the first electrode 31 becomes the first determination value Cth1 or more. If the capacitance of the second electrode 32 becomes the first determination value Cth1 or more before the lapse of time, it is not determined that the front swipe has been performed. Similarly, in the second detection unit 22, in the control circuit 24, after the capacitance of the fourth electrode 34 becomes the first determination value Cth1 or more and before the first determination period Tth1 elapses, the third electrode 33 If the capacitance is equal to or greater than the first determination value Cth1, it is not determined that the previous swipe has been performed.

Further, in the first detection unit 21, the control circuit 24 also refers to a second determination period (hereinafter, also referred to as “second determination period Tth2”” after the capacitance of the first electrode 31 reaches the first determination value Cth1 or more. ), Even if the capacitance of the second electrode 32 becomes the first determination value Cth1 or more, it is not determined that the post-swipe has been performed. Similarly, in the second detection unit 22, the control circuit 24 of the third electrode 33 receives the second determination period Tth2 after the capacitance of the fourth electrode 34 becomes the first determination value Cth1 or more. Even if the capacitance becomes the first determination value Cth1 or more, it is not determined that the previous swipe has been performed.

As shown in FIG. 6, in the detection device 20 attached to the slide door 3, the first detection unit 21 for detecting the rear swipe for opening the slide door 3 from the inside of the vehicle 1 slides. It is located behind the front end of the door 3. On the other hand, the second detection unit 22 for detecting the front swipe for closing the slide door 3 from the inside of the vehicle 1 is located near the front end of the slide door 3.

Therefore, as shown in FIG. 6 (a), when the slide door 3 is in the fully closed state, the first detection unit 21 is located substantially at the center of the door opening 2a in the front-rear direction, and FIG. 6 (b) shows. As shown, when the sliding door 3 is in the fully open state, the second detection unit 22 is located substantially at the center of the door opening 2a in the front-rear direction.

As a result, as shown in FIG. 6A, when the slide door 3 is in the fully closed state, the user inputs an operation to the first detection unit 21 (rear swipe) in order to open the slide door 3. When it is necessary to perform the above, the first detection unit 21 is arranged at a position within the reach of the occupant seated on the side seat of the door opening 2a. Further, as shown in FIG. 6B, when the slide door 3 is in the fully open state, the user needs to input an operation (front swipe) to the second detection unit 22 in order to close the slide door 3. If there is, the second detection unit 22 is arranged at a position within the reach of the occupant seated on the side seat of the door opening 2a.

Next, with reference to the flowchart shown in FIG. 7, a process executed by the control circuit 24 to output an open operation command signal based on the detection result of the first detection unit 21 will be described. It should be noted that this process is, for example, a process executed every predetermined control cycle when the vehicle 1 is stopped.

As shown in FIG. 7, the control circuit 24 determines whether or not the capacitance C1 of the first electrode 31 of the first detection unit 21 is equal to or greater than the first determination value Cth1 (step S11). When the capacitance C1 of the first electrode 31 is less than the first determination value Cth1 (step S11: NO), the control circuit 24 temporarily ends this process. On the other hand, when the capacitance C1 of the first electrode 31 is equal to or greater than the first determination value Cth1 (step S11: YES), the control circuit 24 has elapsed the second determination period Tth2 after the process of step S11 was positively determined. Whether or not it is determined (step S12). When the second determination period Tth2 or more has elapsed (step S12: YES), the control circuit 24 temporarily ends this process. That is, in this case, the capacitance C2 of the second electrode 32 is increased even though a while has passed since the capacitance C1 of the first electrode 31 became the first determination value Cth1 or more. This is a case where the first determination value Cth1 or more is not obtained. Therefore, the control circuit 24 determines that the user has made an unintended operation input to the first detection unit 21.

In the previous step S12, when the second determination period Tth2 has not elapsed (step S12: NO), in the control circuit 24, the capacitance C2 of the second electrode 32 of the first detection unit 21 is the first determination value Cth1. It is determined whether or not it is the above (step S13). When the capacitance C2 of the second electrode 32 is less than the first determination value Cth1 (step S13: NO), the control circuit 24 shifts the process to the previous step S12. In this case, the control circuit 24 continues to determine whether or not the capacitance C2 of the second electrode 32 is equal to or greater than the first determination value Cth1 until the second determination period Tth2 elapses.

When the capacitance C2 of the second electrode 32 is equal to or greater than the first determination value Cth1 (step S13: YES), the control circuit 24 determines that the process of step S11 is affirmative until the process of step S13 is affirmatively determined. In addition, it is determined whether or not the first determination period Tth1 has elapsed (step S14). If the first determination period Tth1 has not elapsed (step S14: NO), the control circuit 24 temporarily ends this process. That is, in this case, the period from when the capacitance C1 of the first electrode 31 becomes the first determination value Cth1 or more to when the capacitance C2 of the second electrode 32 becomes the first determination value Cth1 or more is very long. If it is short. Therefore, the control circuit 24 determines that the user has made an unintended operation input to the first detection unit 21.

On the other hand, in the previous step S14, when the first determination period Tth1 has elapsed (step S14: YES), the control circuit 24 outputs an open operation command signal to the door ECU 10 (step S15). This case is also a case where the control circuit 24 determines that the first detection unit 21 has been swiped afterwards. After that, the control circuit 24 temporarily ends this process.

Next, with reference to the flowchart shown in FIG. 8, the process executed by the control circuit 24 to output the closing operation command signal based on the detection result of the second detection unit 22 will be described. It should be noted that this process is executed every predetermined control cycle, for example, when the vehicle 1 is stopped.

As shown in FIG. 8, the control circuit 24 determines whether or not the capacitance C4 of the fourth electrode 34 of the second detection unit 22 is equal to or greater than the first determination value Cth1 (step S21). When the capacitance C4 of the fourth electrode 34 is less than the first determination value Cth1 (step S21: NO), the control circuit 24 temporarily ends this process. On the other hand, when the capacitance C4 of the fourth electrode 34 is equal to or greater than the first determination value Cth1 (step S21: YES), the control circuit 24 has elapsed the second determination period Tth2 after the process of step S21 was positively determined. Whether or not it is determined (step S22). When the second determination period Tth2 or more has elapsed (step S22: YES), the control circuit 24 temporarily ends this process. That is, in this case, the capacitance C3 of the third electrode 33 is increased even though a while has passed since the capacitance C4 of the fourth electrode 34 became the first determination value Cth1 or more. This is a case where the first determination value Cth1 or more is not obtained. Therefore, the control circuit 24 determines that the user has made an unintended operation input to the second detection unit 22.

In the previous step S22, when the second determination period Tth2 has not elapsed (step S22: NO), in the control circuit 24, the capacitance C3 of the third electrode 33 of the second detection unit 22 is the first determination value Cth1. It is determined whether or not it is the above (step S23). When the capacitance C3 of the third electrode 33 is less than the first determination value Cth1 (step S23: NO), the control circuit 24 shifts the process to the previous step S22. In this case, the control circuit 24 continues to determine whether or not the capacitance C3 of the third electrode 33 becomes the first determination value Cth1 or more until the second determination period Tth2 elapses.

When the capacitance C3 of the third electrode 33 is equal to or greater than the first determination value Cth1 (step S23: YES), the control circuit 24 determines that the process of step S21 is affirmative until the process of step S23 is affirmatively determined. In addition, it is determined whether or not the first determination period Tth1 has elapsed (step S24). If the first determination period Tth1 has not elapsed (step S24: NO), the control circuit 24 temporarily ends this process. That is, in this case, the period from when the capacitance C4 of the fourth electrode 34 becomes the first determination value Cth1 or more to when the capacitance C3 of the third electrode 33 becomes the first determination value Cth1 or more is very long. If it is short. Therefore, the control circuit 24 determines that the user has made an unintended operation input to the second detection unit 22.

On the other hand, in the previous step S24, when the first determination period Tth1 has elapsed (step S24: YES), the control circuit 24 outputs a closing operation command signal to the door ECU 10 (step S25). This case is also a case where the control circuit 24 determines that the second detection unit 22 has been swiped backward. After that, the control circuit 24 temporarily ends this process.

Next, a process executed by the control circuit 24 for determining whether or not the user has performed a front swipe and a rear swipe via the third detection unit 23 will be described. Since there are many parts of this process that overlap with the above-mentioned processes, the flow chart will be omitted and the description will be simplified.

The control circuit 24 outputs an open operation command signal to the door ECU 10 when the capacitance becomes the second determination value Cth2 or more in the order of the fifth electrode 35, the sixth electrode 36, and the seventh electrode 37. Further, the control circuit 24 outputs a closing operation command signal to the door ECU 10 when the capacitance becomes the second determination value Cth2 or more in the order of the seventh electrode 37, the sixth electrode 36, and the fifth electrode 35. On the other hand, in other cases, the control circuit 24 does not output the open operation command signal and the close operation command signal to the door ECU 10.

Next, the operation of the present embodiment will be described together with the effect.
(1) A first detection unit 21 for detecting an opening operation input (rear swipe) is arranged at a position closer to the first end X1 in the longitudinal direction X of the detection device 20, and a second detection device 20 is arranged in the longitudinal direction X. A second detection unit 22 for detecting a closing operation input (front swipe) is arranged at a position closer to the end X2. Therefore, by attaching the detection device 20 to the slide door 3 so that the first end X1 and the second end X2 of the detection device 20 are on the rear side and the front side of the vehicle 1, respectively, depending on the open / closed state of the slide door 3. The first detection unit 21 and the second detection unit 22 are arranged as follows.

That is, as shown in FIG. 6A, when the slide door 3 is in the fully closed state, the first detection unit 21 is arranged at a position rearward from the front end of the door opening 2a. Further, as shown in FIG. 6B, when the slide door 3 is in the fully open state, the second detection unit 22 is arranged at a position rearward from the front end of the door opening 2a. Therefore, the distance from the user seated on the side seat of the door opening 2a to the first detection unit 21 when the slide door 3 is in the fully closed state, and when the slide door 3 is fully open from the user. Both the distance to the second detection unit 22 and the distance tend to be short. That is, the first detection unit 21 and the second detection unit 22 are arranged at positions where the occupant seated on the side seat of the door opening 2a can easily operate. In this way, the user can easily operate the detection device 20 to open / close the slide door 3 regardless of the open / closed state of the slide door 3.

(2) The first detection unit 21 and the second detection unit 22 are used as capacitance sensors. Therefore, the user can input the operation by bringing his / her hand close to the first detection unit 21 and the second detection unit 22 or bringing his / her hand into contact with the first detection unit 21 and the second detection unit 22. can. In other words, the user can perform operation input without pulling or turning the inside door handle, for example. In this way, the burden on the user when performing operation input can be reduced.

(3) For example, when the distance between the user seated in the seat and the detection device 20 provided on the slide door 3 is short, the user's body is the electrodes 31 to 34 of the first detection unit 21 and the second detection unit 22. May approach. In this case, the control circuit 24 may output an open operation command signal and a closed operation command signal based on an operation input not intended by the user.

In this regard, according to the above embodiment, on condition that the capacitance of the electrodes 31 to 34 is equal to or higher than the lower limit value (first determination value Cth1) for determining the contact of the user's hand with the detection device 20. The control circuit 24 outputs an open operation command signal and a closed operation command signal. That is, the control circuit 24 outputs an open operation command signal and a closed operation command signal on condition that the user inputs an operation while the user touches the detection device 20. As a result, it is suppressed that the slide door 3 is opened and closed based on an operation input not intended by the user.

(4) For example, when a user sitting in a seat leans against the slide door 3, a part of the user's body may approach the first detection unit 21 and the second detection unit 22. In this case, the control circuit 24 may output an open operation command signal and a closed operation command signal based on an operation input not intended by the user. However, in this case, a part of the user's body approaches the plurality of electrodes 31 to 34 constituting the first detection unit 21 and the second detection unit 22 at the same time, so that the capacitance of the plurality of electrodes 31 to 34 is electrostatic. The capacity tends to increase at the same time.

Therefore, in the above embodiment, when the electrodes 31 to 34 having higher capacitances are switched in a specific order in the first detection unit 21 and the second detection unit 22, the open operation command signal and the close operation command signal are output. Will be done. Therefore, it is further suppressed that the slide door 3 is opened and closed based on an operation input not intended by the user.

(5) The control circuit 24 outputs an open operation command signal to the door ECU 10 when a rear swipe is performed on the first detection unit 21, and a front swipe is performed on the second detection unit 22. Occasionally, a closing operation command signal is output to the door ECU 10. Therefore, while suppressing the complexity of the operation input, it is possible to suppress the opening and closing operation of the slide door 3 due to the operation input not intended by the user.

(6) The detection device 20 includes a first detection unit 21 and a second detection unit 22 that detect an operation input from the inside of the vehicle 1, a third detection unit 23 that detects an operation input from the outside of the vehicle 1. To be equipped. Therefore, one detection device 20 can open and close the slide door 3 based on the operation input from the inside and the outside of the vehicle 1.

(7) When the user is seated on the side seat of the slide door 3, the presence of the user in the vicinity of the first detection unit 21 and the second detection unit 22 means that the first detection unit 21 and the second detection unit 21 and the second detection unit 22 are present. There are many opportunities for the capacitance of the electrodes 31 to 34 of the unit 22 to increase. That is, the first detection unit 21 and the second detection unit 22 are more likely to detect an operation input not intended by the user than the third detection unit 23.

Therefore, in the above embodiment, whether or not the control circuit 24 outputs the open operation command signal and the closed operation command signal based on the detection results of the first detection unit 21, the second detection unit 22, and the third detection unit 23. There is a difference in the judgment values used for the determination. Specifically, the first determination value Cth1 is made larger than the second determination value Cth2. Therefore, it is possible to suppress the opening / closing operation of the slide door 3 based on the operation input not intended by the user from the inside of the vehicle 1.

(8) In the longitudinal direction X of the detection device 20, the amount of movement when the slide door 3 moves between the fully closed state and the fully open state by the distance between the first detection unit 21 and the second detection unit 22. The distance was about the same as. Therefore, as shown in FIGS. 6A and 6B, the second detection unit 22 and the slide when the slide door 3 is in the fully open state with reference to the user seated on the side of the door opening 2a. The first detection unit 21 when the door 3 is in the fully closed state can be arranged at substantially the same position. As a result, the occupant can more easily input the operation input for opening / closing the slide door 3 to the detection device 20.

(9) The period from when the capacitance of the first electrode 31 of the first detection unit 21 becomes the first determination value Cth1 or more to when the capacitance of the second electrode 32 becomes the first determination value Cth1 or more is extreme. If it is too short or the synchronization period is extremely long, the control circuit 24 does not output the open operation command signal. Similarly, the period from when the capacitance of the fourth electrode 34 of the second detection unit 22 becomes the first determination value Cth1 or more to when the capacitance of the third electrode 33 becomes the first determination value Cth1 or more is extreme. If it is too short or extremely long, the control circuit 24 does not output an open operation command signal. Therefore, it is possible to further suppress the opening / closing operation of the slide door 3 based on the operation input not intended by the user from the inside of the vehicle 1.

The above embodiment may be changed as shown below.
The control circuit 24 may output a closing operation command signal to the door ECU 10 when it is determined that the front swipe has been performed on the first detection unit 21. Further, the control circuit 24 may output an open operation command signal to the door ECU 10 when it is determined that the second detection unit 22 has been swiped backward.

The number of electrodes constituting the first detection unit 21 and the second detection unit 22 may be one. In this case, the control circuit 24 outputs the open operation command signal and closes when the capacitance of one electrode constituting the first detection unit 21 and the second detection unit 22 becomes the first determination value Cth1 or more. It is preferable to output the operation command signal to the door ECU 10.

The number of electrodes constituting the first detection unit 21 and the second detection unit 22 may be three or more. In this case, it is preferable that the control circuit 24 outputs the open operation command signal and the close operation command signal to the door ECU 10 when the operation inputs such as tracing the electrodes in a specific order are performed.

-The first determination value Cth1 and the second determination value Cth2 may be appropriately changed. For example, the first determination value Cth1 may be equal to the second determination value Cth2.
The control circuit 24 swipes forward and backward based on the order of the times when the capacitances of the electrodes 31 to 37 of the first detection unit 21, the second detection unit 22, and the third detection unit 23 reach their peak values. May be determined whether or not Further, in the control circuit 24, the capacitance of the electrodes 31 to 37 of the first detection unit 21, the second detection unit 22, and the third detection unit 23 is less than a predetermined determination value (for example, the first determination value Cth1). It may be determined whether or not the front swipe and the back swipe have been performed based on the order of the time. As described above, in the control circuit 24, the front swipe and the rear swipe are performed based on the order in which the capacitances of the electrodes 31 to 37 of the first detection unit 21, the second detection unit 22, and the third detection unit 23 change. It may be determined whether or not it has been damaged.

When the door lock 6 is locked, the door ECU 10 does not have to open the slide door 3 even when an open operation command signal from the control circuit 24 is input.
The door ECU 10 may unlock the door lock 6 before the opening operation of the sliding door 3 based on the opening operation command signal from the control circuit 24. Further, the door ECU 10 may lock the door lock 6 after the sliding door 3 is closed based on the closing operation command signal from the control circuit 24.

When a specific operation input is made to the first detection unit 21, the second detection unit 22, and the third detection unit 23 during the opening / closing operation of the slide door 3, the control circuit 24 stops the slide door 3. You may let me. The specific operation input may be an operation in which the user brings his / her hand close to any of the electrodes 31 to 37 of the first detection unit 21, the second detection unit 22, and the third detection unit 23.

The detection device 20 may further include a fourth detection unit that detects an operation input for stopping the slide door 3 during the opening / closing operation of the slide door 3. In this case, the fourth detection unit is preferably arranged between the first detection unit 21 and the second detection unit 22.

The first detection unit 21 and the second detection unit 22 may be so-called push switches, optical sensors, ultrasonic sensors, heat sensing sensors, and the like. Even in this case, the effect (1) of the above embodiment can be obtained.

-The detection device 20 does not have to include the third detection unit 23.
The mounting position of the detection device 20 with respect to the slide door 3 may be on the door trim forming the design of the vehicle interior, or may be the window frame supporting the window glass 5.

The distance between the first detection unit 21 and the second detection unit 22 in the longitudinal direction X of the detection device 20 depends on the amount of movement when the slide door 3 moves between the fully closed state and the fully open state. The distance may be changed as appropriate as long as it does not deviate significantly from the movement amount. However, in this case, the position of the first detection unit 21 when the slide door 3 is in the fully closed state and the position of the second detection unit 22 when the slide door 3 is in the fully open state are the positions of the slide door 3. It is preferable that the occupant seated on the side seat is within the range where the operation input can be performed without changing the posture.

The detection device 20 does not have to include a housing 26 for accommodating the constituent members of the detection device 20. In this case, the first determination value Cth1 is the first detection unit 21 (first electrode 31 and second electrode 32) and the second detection unit 22 (third electrode 34 and fourth electrode 34) of the user's hand as the detection target. ) Is preferably set as a preset determination value as a lower limit value for determining contact with.
