JP 7-54525 A

  In recent years, with the diversification of in-vehicle functions, the number of electronic key switches tends to increase. For example, when opening the sliding door, the user operates a sliding door opening switch. When closing the slide door, the user operates the slide door close switch. Here, the user sometimes wants to cancel the control during the execution of the control. For example, when the user notices that an object may be caught by the sliding door while the sliding door is moving in the closing direction, the user selectively operates the sliding door opening switch among a plurality of switches immediately. . Thereby, the control related to the movement of the sliding door in the closing direction is canceled and switched to the movement in the opening direction. In such a case, it is difficult for the user to selectively operate the slide door opening switch immediately because the user is in a mentally tense state. This is not limited to a sliding door, and the same applies to an operation related to opening and closing of a power window, for example.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an electronic key that can more smoothly cancel control of a control target during control execution.

Hereinafter, means for achieving the above-described object and its operation and effects will be described.
According to a first aspect of the present invention, there is provided an electronic key comprising: an electronic key that transmits a control request signal for requesting control by a user operation; and a control target that executes control based on the received control request signal. In the system, the electronic key includes a switch that transmits a radio signal from the electronic key when operated by a user, and the control target is a period of executing control according to the received control request signal In the present invention, when the wireless signal is received, the gist is to cancel the control being executed.

  According to this configuration, the control being executed in the control target is canceled based on the radio signal transmitted through the switch operation of the electronic key. That is, when it is desired to cancel the control being executed, any switch operation may be performed regardless of the control content. Therefore, the control during the control execution can be canceled smoothly.

  According to a second aspect of the present invention, in the electronic key system according to the first aspect, the switch is operated when transmitting an unlock request signal as the wireless signal for requesting the unlocking of the vehicle door. An unlock switch, and a lock switch operated when transmitting a lock request signal as the radio signal for requesting locking of the vehicle door, and the control object is the received control request signal. If the unlock request signal or the lock request signal is received during the period in which the control is executed in accordance with the control, the gist is to cancel the control being executed.

  According to this configuration, the control being executed is canceled by operating the unlock switch or the lock switch while the control is being executed. That is, when the user wants to cancel the control being executed, the user may operate either the unlock switch or the lock switch. At this time, since it is not necessary to select and operate the switch type, the control during the execution of the control is smoothly canceled.

  According to a third aspect of the present invention, in the electronic key system according to the second aspect, the electronic key system includes a motion sensor that detects a movement of the electronic key, and the electronic key is operated by the unlock switch or the lock switch. When it is determined that the swing operation has been performed based on the detection result of the motion sensor, a control request signal is transmitted to request that the opening / closing body be moved in response to the swing operation. When the unlocking request signal or the locking request signal is received during the period in which the control for moving the opening / closing body is executed in response to the control request signal, the opening / closing body of the opening / closing body is canceled after canceling the control being executed. The gist is to reverse the direction of movement.

  According to the configuration, the opening / closing body moves through the swinging operation of the electronic key. For example, when the opening / closing body is moving in the closing direction, when the user notices that the object contacts the opening / closing body as it is, the user performs the switch operation of the electronic key. Thereby, the moving direction of the opening / closing body is reversed, and the movement in the opening direction is started. Thereby, it is suppressed that an object contacts an opening-and-closing body.

  According to the present invention, in the electronic key system, it is possible to cancel the control of the control target during control execution more smoothly.

(First embodiment)
Hereinafter, a first embodiment embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1, an electronic key system 1 is mounted on the vehicle of this embodiment. The electronic key system 1 is capable of unidirectional communication between an electronic key 2 (transmitting side) possessed by a vehicle user and an in-vehicle device 3 (receiving side) provided on the vehicle side.

  As shown in FIG. 2, the electronic key 2 includes a lock switch 27 that is operated when the vehicle door is locked on the surface thereof, and an unlock switch 26 that is operated when the vehicle door is unlocked. Yes. The lock switch 27 and the unlock switch 26 are push switches.

  The user can lock the vehicle door by pressing the lock switch 27. Furthermore, the user can move the window of the vehicle in the closing direction (upward) to make it fully closed by swinging the electronic key 2 while keeping the lock switch 27 pressed. it can. Further, the user can unlock the vehicle door by pressing the unlock switch 26. Furthermore, the user can move the vehicle window in the opening direction (downward) to the fully open state by swinging the electronic key 2 downward while keeping the unlock switch 26 pressed. it can. Further, the user can reverse the moving direction of the window by operating the lock switch 27 or the unlock switch 26 while the window is moving. Hereinafter, the configuration of the electronic key system 1 will be described.

(Electronic key 2)
As shown in FIG. 1, the electronic key 2 includes a microcomputer 23, a transmission circuit 24, a transmission antenna 25, and an acceleration sensor 21 in addition to the lock switch 27 and the unlock switch 26. The electronic key 2 incorporates a battery (not shown), and operating power is supplied to each part from the battery.

  The acceleration sensor 21 detects a voltage corresponding to the acceleration generated when the electronic key 2 is shaken, and outputs the detection result to the microcomputer 23. The acceleration sensor 21 in the present embodiment can detect acceleration in three axis directions (X axis, Y axis, Z axis in the XYZ coordinate system). The acceleration sensor 21 may be a mechanical type, an optical type, a semiconductor type, or the like, but may be any type as long as it can be incorporated in the electronic key 2 and can detect acceleration based on a swing operation.

  The microcomputer 23 includes a non-volatile memory 23a. In the memory 23a, various numerical values (setting range and setting time) that serve as a determination criterion for the presence or absence of a swing operation, and an ID code (identification code) unique to the electronic key 2 are stored. ) Is stored. The microcomputer 23 determines the presence / absence of the swing operation and the direction of the swing operation based on the detection result of the acceleration sensor 21, and determines the control content desired by the user based on the determination result. A method for determining the control contents based on the swing operation and the swing direction by the microcomputer 23 will be described in detail later.

  When the unlock switch 26 is operated, an operation signal Su indicating that is output to the microcomputer 23, and when the lock switch 27 is operated, an operation signal S1 indicating that is output to the microcomputer 23. The operation signals Su and Sl continue to be output as long as the unlock switch 26 or the lock switch 27 is pressed, and the output stops when it is not pressed. The microcomputer 23 detects whether or not the unlock switch 26 or the lock switch 27 is operated based on whether or not the operation signals Su and Sl are input.

  Here, the microcomputer 23 supplies power to the acceleration sensor 21 in response to the input of any one of the operation signals Su and Sl, activates it, and based on the detection result of the acceleration sensor 21, whether or not the swing operation is performed and the swing operation Judgment of direction is started. The microcomputer 23 stops the supply of power to the acceleration sensor 21 when the operation signals Su and Sl cannot be detected. That is, the microcomputer 23 does not determine the presence / absence of the swing operation and the direction of the swing operation without supplying power to the acceleration sensor 21 during a period in which the operation signals Su and Sl are not detected.

  When the microcomputer 23 recognizes that the unlock switch 26 has been operated through the input of the operation signal Su, the microcomputer 23 generates an unlock request signal including an ID code and a code requesting to unlock the door. The data is output to the transmission circuit 24. The transmission circuit 24 modulates the unlock request signal input from the microcomputer 23 and transmits it as a radio signal in the UHF (Ultra High Frequency) band via the transmission antenna 25.

  Furthermore, the microcomputer 23 includes an ID code and a code requesting to open a window when it is determined that there is a downward swing operation in a state where the operation signal Su is continuously input. A window opening request signal is generated and output to the transmission circuit 24. The transmission circuit 24 modulates the window opening request signal input from the microcomputer 23 and transmits it as a UHF band radio signal via the transmission antenna 25.

  In addition, when the microcomputer 23 recognizes that the lock switch 27 has been operated through the input of the operation signal Sl, the microcomputer 23 generates a lock request signal including an ID code and a code for requesting locking of the door, and transmits it. Output to the circuit 24. The transmission circuit 24 modulates the lock request signal input from the microcomputer 23 and transmits it as a UHF band radio signal via the transmission antenna 25.

  Further, the microcomputer 23 includes an ID code and a code requesting to close the window when it is determined that there is an upward swing operation in a state where the operation signal S1 is continuously input. A closing window request signal is generated and output to the transmission circuit 24. The transmission circuit 24 modulates the closing window request signal input from the microcomputer 23 and transmits it as a UHF band radio signal via the transmission antenna 25.

(In-vehicle device)
The in-vehicle device 3 includes a reception antenna 31, a reception circuit 32, and an in-vehicle control unit 33. The receiving antenna 31 receives various request signals (locking request signal, unlocking request signal, opening window request signal, closing window request signal) transmitted from the electronic key 2. The receiving circuit 32 demodulates various requests received through the receiving antenna 31 and outputs them to the in-vehicle control unit 33.

The in-vehicle control unit 33 includes a nonvolatile memory 33a, and the memory 33a stores the same ID code as the ID code of the electronic key 2.
The in-vehicle control unit 33 collates the ID code included in various request signals from the receiving circuit 32 with the ID code stored in the memory 33a. When the signal from the receiving circuit 32 is an unlock request signal, the in-vehicle controller 33 unlocks the vehicle door through the door control device 40 when the ID code verification is established.

Further, when the signal from the receiving circuit 32 is a lock request signal, the in-vehicle controller 33 locks the vehicle door through the door control device 40 when the ID code verification is established.
When the signal from the receiving circuit 32 is a window opening request signal and the ID code verification is established, the in-vehicle control unit 33 shifts to the panic detection mode and opens the window through the power window device 41. Move in the opening direction.

  When the signal from the receiving circuit 32 is a closing window request signal, the in-vehicle control unit 33 shifts to the panic detection mode when the ID code verification is established, and sets the window to the fully closed state through the power window device 41. Move in the closing direction until

  In the panic detection mode, the in-vehicle control unit 33 monitors the presence / absence of the lock request signal or the unlock request signal over the second set time T2. The second set time T2 is set to a time required for the window to change from the fully closed state to the fully open state. The in-vehicle control unit 33 reverses the moving direction of the window through the power window device 41 when receiving the lock request signal or the unlock request signal in the panic detection mode.

Next, a method for determining the direction of the swing operation of the electronic key 2 by the microcomputer 23 will be specifically described.
The direction of the swing of the electronic key 2 in each axial direction can be determined by the plus or minus of the output signal (voltage value) that is the detection result of the acceleration in each axial direction from the acceleration sensor 21. This makes it possible to determine which direction the electronic key 2 is swung up and down.

  As illustrated in FIG. 2, the XYZ axes at which the acceleration sensor 21 detects acceleration with respect to the electronic key 2 are set to be orthogonal to each other. Specifically, the X-axis is in the direction along the long side of the electronic key 2, the Y-axis is in the direction along the short side of the electronic key 2, the Z-axis is in the direction perpendicular to the surface on which the switches 26 and 27 of the electronic key 2 are provided, Are each extended.

  As shown in FIG. 3, the movement of the electronic key 2 is the same when the output signal (voltage value), which is the detection result of acceleration in the predetermined axis direction by the acceleration sensor 21, is positive or negative. The direction is the opposite direction. For example, as shown in FIG. 2, a case will be described in which the electronic key 2 is swung in the gravitational direction in a state where the Z-axis direction of the electronic key 2 coincides with the gravitational direction. As shown in FIG. 3, in the direction of gravity, different signals (voltage values) are generated depending on whether the signal is shaken upward or when it is shaken downward. Specifically, the microcomputer 23 determines that it is swung upward when the voltage is positive, and determines that it is swung downward when the voltage is negative.

  As shown in FIG. 4, the microcomputer 23 determines that a swing operation has been performed when acceleration that deviates from the first set range A is detected over the first set time T1. The first set time T1 and the first set range A are stored in advance in the memory 23a of the microcomputer 23. Here, compared with the vibration etc. accompanying walking illustrated by the two-dot chain line in FIG. The first setting range A is a range that includes acceleration due to vibration accompanying walking, for example, by simulation, and is set so that the acceleration that accompanies the swing operation deviates from the first setting range A.

  If the acceleration detected by the acceleration sensor 21 does not deviate from the first setting range A, or if the state does not continue for the first setting time T1 even if deviating from the first setting range A, the microcomputer 23 does not determine that the swing operation has been performed.

  Next, the processing procedure of the microcomputer 23 and the in-vehicle control unit 33 will be described with reference to the flowchart of FIG. This flowchart is started when the operation signals Sl and Su are input through the operation of the lock switch 27 or the unlock switch 26.

  The microcomputer 23 transmits a locking request signal or an unlocking request signal according to the input operation signals S1 and Su (S101). Then, the microcomputer 23 determines whether or not the operation signals S1 and Su are continuously input (S102). When the microcomputer 23 determines that the operation signals Sl and Su are not continuously input (NO in S102), that is, when the push operation of the lock switch 27 or the unlock switch 26 is released, the window opening request signal The flowchart is terminated without transmitting the above. When the microcomputer 23 determines that the operation signals Sl and Su are continuously input (YES in S102), that is, when the push operation of the lock switch 27 or the unlock switch 26 is continued, the presence or absence of the swing operation Is determined (S103).

  If the microcomputer 23 determines that there is no swing operation (NO in S103), the microcomputer 23 ends the flowchart without transmitting a window opening request signal or the like. If the microcomputer 23 determines that there is a swing operation (YES in S103), the microcomputer 23 determines the swing operation direction (S104). Then, the microcomputer 23 transmits an opening window request signal or a closing window request signal according to the swing operation direction (S105).

When receiving the window opening request signal or the window closing request signal, the in-vehicle control unit 33 shifts to the panic detection mode and moves the window in the opening / closing direction according to the signal (S106).
The in-vehicle control unit 33 determines whether or not the time from the start of the mode has passed the second set time T2 in the panic detection mode (S107). When determining that the second set time T2 has not elapsed (NO in S107), the in-vehicle controller 33 determines whether or not to receive a lock request signal or an unlock request signal (S108). Here, even when the in-vehicle control unit 33 is in the panic detection mode, the microcomputer 23 receives the operation signals Sl and Su through the operation of the lock switch 27 or the unlock switch 26 as in the above-described step S101. Send unlock request signal.

  When receiving the lock request signal or the unlock request signal (YES in S108), the in-vehicle controller 33 reverses the moving direction of the window (S109). When the in-vehicle control unit 33 does not receive the lock request signal or the unlock request signal (NO in S108), it determines again whether the time from the start of the panic detection mode has passed the second set time T2 (S107). ). That is, in the panic detection mode, the presence / absence of the unlock request signal or the lock request signal through the operation of the unlock switch 26 or the lock switch 27 is monitored over the second set time T2.

Further, when it is determined that the time from the start of the panic detection mode has passed the second set time T2 (YES in S107), the in-vehicle control unit 33 ends the flowchart.
Next, a series of operations of the electronic key 2 by the user will be described.

  First, when getting on, the user presses the unlock switch 26 of the electronic key 2. Further, to open the window, the electronic key 2 is swung downward while keeping the unlock switch 26 pressed. At this time, an unlock request signal and a window opening request signal are sequentially transmitted from the electronic key 2. As a result, the in-vehicle control unit 33 opens the window downward after unlocking the vehicle door.

  When getting off, the user presses the lock switch 27 of the electronic key 2. Further, in order to close the window, the electronic key 2 is swung upward while keeping the lock switch 27 pressed. As a result, a lock request signal and a closing window request signal are sequentially transmitted from the electronic key 2. As a result, the in-vehicle controller 33 moves the window in the closing direction after locking the vehicle door. In the closing operation of the window, for example, when the user notices that an object is sandwiched between the window and the window frame as it is, the user presses one of the unlock switch 26 and the lock switch 27. As a result, an unlock request signal or a lock request signal is transmitted from the electronic key 2, and based on this, the window that has been moved in the closing direction is reversed in the opening direction.

  Here, in the panic detection mode, since the moving direction of the slide door 6 can be reversed by operating either the unlock switch 26 or the lock switch 27, the unlock switch 26 and the lock switch 27 must be kept silent. Operation is possible. For this reason, the moving direction of the window can be reversed immediately even when the user is mentally tense. Therefore, it is possible to more smoothly suppress the object from being caught by the window.

As described above, according to the embodiment described above, the following effects can be obtained.
(1) In the panic detection mode, the moving direction of the window can be reversed by the lock request signal or the unlock request signal transmitted through the operation of the unlock switch 26 or the lock switch 27 of the electronic key 2. That is, even when the user is mentally tense, by operating any one of the switches on the electronic key 2, it is possible to more smoothly suppress the object from being caught by the window.

  Further, the in-vehicle control unit 33 shifts to the panic detection mode. For this reason, the electronic key 2 (microcomputer 23) may be processed in the same manner as before. Specifically, the microcomputer 23 transmits a lock request signal or an unlock request signal according to the operation of the lock switch 27 or the unlock switch 26 regardless of the mode of the in-vehicle control unit 33.

  (2) Only when the lock switch 27 or the unlock switch 26 is operated, the presence / absence of the swing operation is determined. Therefore, it is possible to prevent an erroneous input due to a determination that an operation that the user does not intend to perform is a swing operation.

  (3) When the user gets off, the user operates the lock switch 27 to lock the vehicle door. The user performs a swing operation while keeping the operation state of the lock switch 27 after locking, so that the microcomputer 23 fully closes the window. Thus, the user can make the state of the vehicle an initial state suitable for the user to get off and leave the vehicle by a continuous operation from the locking of the vehicle door. Further, since the lock switch 27 has an image of being locked, that is, “closed”, it can be understood that if the swing operation in a state where the lock switch 27 is operated sensuously is a window, the lock switch 27 is closed.

  (4) When the user gets on the vehicle, the user operates the unlock switch 26 to unlock the vehicle door. The user can swing the microcomputer 23 by opening the window by keeping the operation state of the unlock switch 26 after unlocking. Further, since the unlock switch 26 has an image of unlocking, that is, “opening”, it can be understood that the user can open the swing operation in a state where the unlock switch 26 is operated sensuously if it is a window.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. This embodiment is different from the first embodiment in that the sliding door is controlled to be opened and closed by an electronic key swing operation. Hereinafter, a description will be given focusing on differences from the first embodiment. Note that the electronic key system of this embodiment has substantially the same configuration as the electronic key system of the first embodiment shown in FIG. Hereinafter, a description will be given focusing on differences from the first embodiment.

  As shown by a two-dot chain line in FIG. 1, the vehicle is provided with a sliding door device 42. Specifically, as shown in FIG. 6, on both sides of the vehicle, a hinge door 7 is provided on the front side, and a slide door 6 is provided on the rear side. The hinge door 7 can be opened and closed around a hinge 7a provided on the front side of the hinge door 7 extending in the vehicle height direction (the paper surface direction in FIG. 6). The sliding door 6 can be opened and closed by sliding in the front-rear direction with respect to the vehicle.

  The sliding door 6 is provided with a door handle 8 at a position where the sliding door 6 can be operated from inside and outside, and the sliding door 6 can be manually opened and closed by pushing and pulling while holding the door handle 8. The sliding door 6 can be automatically opened and closed through a swinging operation of the electronic key 2. Hereinafter, when particularly necessary in the description, the right slide door 6 with respect to the traveling direction (forward direction) of the vehicle is referred to as a right slide door 6R, and the left slide door 6 is referred to as a left slide door 6L.

Next, a method for operating the electronic key 2 will be briefly described.
Similar to the first embodiment, the user can lock and unlock the slide door 6 and the hinge door 7 by pressing the unlock switch 26 or the lock switch 27 of the electronic key 2. Furthermore, the sliding door 6 can be automatically opened and closed in the same direction by swinging in the direction in which the sliding door 6 is desired to be moved while keeping the unlock switch 26 or the lock switch 27 pressed.

Hereinafter, the operation of the microcomputer 23 will be mainly described.
Specifically, upon receiving the operation signals Su and Sl, the microcomputer 23 transmits an unlock request signal or a lock request signal through the transmission circuit 24.

Then, the microcomputer 23 determines the requested control content based on the swing operation direction in the state where the operation signals Sl and Su are detected, according to the map of FIG. 7 stored in its own memory.
Specifically, the microcomputer 23 requests that the ID code and the left sliding door 6L be opened when it is determined that there is a swinging operation in the right direction as viewed from the user in the state where the operation signal Su is detected. An open left door request signal including the following code is generated and output to the transmission circuit 24. As shown in FIG. 6, when the unlock switch 26 is operated and shaken in the right direction as viewed from the user, it is limited to the left slide door 6 </ b> L that opens rightward as viewed from the user outside the vehicle. Is assumed to be swinging facing the left sliding door 6L.

  Further, when the microcomputer 23 detects the operation signal Su and determines that there is a swinging operation in the left direction as viewed from the user, the microcomputer 23 provides an ID code and a code requesting to open the right slide door 6R. An open right door request signal is generated and output to the transmission circuit 24. As shown in FIG. 6, when the unlock switch 26 is operated and shaken leftward as viewed from the user, it is limited to the right slide door 6 </ b> R that opens leftward as viewed from the user outside the vehicle. Is assumed to be swinging in opposition to the right sliding door 6R.

  Further, when the microcomputer 23 determines that there is a swinging operation in the right direction in the state where the operation signal Su is detected, the microcomputer 23 includes the ID code and the closing right including the code requesting to close the right sliding door 6R. A door request signal is generated and output to the transmission circuit 24. As shown in FIG. 6, when the lock switch 27 is operated and is swung in the right direction as viewed from the user, it is limited to the right slide door 6R that is closed in the right direction as viewed from the user outside the vehicle. It is assumed that the user performs a swing operation facing the right slide door 6R.

  If the microcomputer 23 detects that the operation signal Su is detected and determines that there is a leftward swing operation, the microcomputer 23 includes an ID code and a code indicating that the left slide door 6L is requested to be closed. A door request signal is generated and output to the transmission circuit 24. As shown in FIG. 6, when the lock switch 27 is operated and is swung leftward as viewed from the user, it is limited to the left slide door 6L that closes leftward as viewed from the user outside the vehicle. It is assumed that the user performs a swinging operation facing the left slide door 6L.

  Here, although the swing direction of the electronic key 2 can be determined based on the detection result of the acceleration sensor 21, the standing position of the user is unknown only by the swing direction. It is not possible to judge whether it has been swung. Therefore, when the microcomputer 23 determines that the electronic key 2 has been swung, the microcomputer 23 calculates a swing trajectory based on the swing direction, and it is estimated that there is a user who swings the electronic key 2 based on the trajectory. The estimated user position 60 shown in FIG. 8 is calculated.

  Specifically, as shown in FIG. 8, when the electronic key 2 is swung along the XY plane, the microcomputer 23 combines the acceleration in the XY axis direction detected by the acceleration sensor 21 to turn the swing direction. Judging. Here, when the electronic key 2 is swung non-linearly, the swinging direction changes from moment to moment. The microcomputer 23 calculates the trajectory of the swing of the electronic key 2 based on the change in the swing direction. Here, when the user shakes the electronic key 2 in the left-right direction, the locus of the swing is an arc shape when the user shakes it with a joint such as a shoulder, elbow or wrist. The microcomputer 23 calculates the center point of the arc as the user estimated position 60 based on the curvature of the arc that is the trajectory of the swing of the electronic key 2. By calculating the user estimated position 60, it is possible to determine whether the swing operation of the electronic key 2 has been made to the left or right direction with respect to the user (user estimated position 60).

  The transmission circuit 24 receives the open right door request signal, the open left door request signal, the close right door request signal, and the close left door request signal (hereinafter collectively referred to as various slide door request signals) input from the microcomputer 23. The signal is modulated and transmitted as a radio signal in the UHF band through the transmission antenna 25.

  The receiving circuit 32 demodulates various sliding door request signals received through the receiving antenna 31 and outputs them to the in-vehicle control unit 33. The in-vehicle control unit 33 opens the right sliding door 6R through the sliding door device 42 when the ID code included in the open right door request signal from the receiving circuit 32 is matched with the ID code stored in the memory 33a. Move in the direction. Hereinafter, similarly, the vehicle-mounted control unit 33 moves the left slide door 6L in the opening direction when the ID code verification is established for the open left door request signal. The vehicle-mounted control unit 33 moves the right slide door 6R in the closing direction when the ID code verification is established for the closed right door request signal, and the left slide door when the ID code verification is established for the closed left door request signal. 6L is moved in the closing direction. Moreover, the vehicle-mounted control part 33 will transfer to panic detection mode, if various slide door request signals are received.

  The in-vehicle control unit 33 reverses the moving direction of the sliding door through the sliding door device 42 when receiving the locking request signal or the unlocking request signal in the panic detection mode. That is, the same processing as the flowchart of FIG. 5 is executed except that the signal transmitted in step S105 of FIG. 5 is various sliding door request signals and the control target of steps S106 and S109 is the sliding door 6. Is done. As a result, similarly to the first embodiment, an object is prevented from being caught in the slide door 6 based on the operation of the unlock switch 26 or the lock switch 27 in the panic detection mode.

In addition, when the sliding door 6 is opening, there is no risk of the pinching,
There is a possibility that the sliding door 6 moving in the opening direction may come into contact with an object. Therefore, by operating the unlock switch 26 or the lock switch 27 when the user notices that the slide door 6 is in contact with the object as it is, the slide door 6 can be reversed to avoid the contact. it can.

As described above, according to the embodiment described above, the following effects can be obtained.
(5) When the slide door 6 moves in the closing direction, if the user notices that an object is caught between the slide door 6 and the slide door frame, the unlock switch 26 or the lock switch By operating 27, the slide door 6 can be moved in the opening direction. In this way, even in a state of being mentally tightened, the moving direction of the slide door 6 can be reversed by operating any one of the switches anyway. Therefore, the object can be prevented from being caught by the slide door 6.

  (6) If the user swings the electronic key 2 in the direction in which the slide door 6 is desired to move, the slide door 6 can be opened and closed in that direction. Therefore, a mistake in the swing direction is unlikely to occur, and an erroneous input based on a mistake in the swing operation direction can be prevented.

  (7) By calculating the user estimated position 60, it is possible to determine whether the swing operation of the electronic key 2 has been performed in the opening direction or the closing direction of the slide door 6 with respect to the user (user estimated position 60). .

(Third embodiment)
A third embodiment in which the present invention is embodied in an electronic key system will be described below with reference to FIGS. The electronic key system according to this embodiment is different from the first embodiment in that the electronic key system includes means for preventing the sliding door 6 that is not a desired operation target from opening and closing when the swing direction is wrong. Yes. Hereinafter, a description will be given focusing on differences from the first embodiment. In addition, the electronic key system 1 of this embodiment is equipped with the structure substantially the same as the electronic key system 1 of 2nd Embodiment shown in FIG.

  As shown by a two-dot chain line in FIG. 1, the electronic key 2 is provided with a key side azimuth sensor 28 that detects the direction in which the electronic key 2 faces by using geomagnetism, and the in-vehicle device 3 also uses the geomagnetism. A vehicle-side azimuth sensor 35 that detects the azimuth of the vehicle is provided.

  The microcomputer 23 calculates the user estimated position 60 based on the swing trajectory of the electronic key 2 described in the second embodiment, and estimates that the user is facing based on the swing trajectory and the user estimated position 60. The user direction estimation direction 62, which is a direction to be calculated, is calculated. Generally, the user performs a swing operation of the electronic key 2 in front of the user. For example, as shown in FIG. 9, when the user swings the electronic key 2 to the left as viewed from the user, the user passes the electronic key 2 held by the right hand, for example, from the front right side to the front of the user. Shake until the front left side. Therefore, the microcomputer 23 estimates that the direction from the user estimated position 60 to the intermediate point 61 is the user direction, assuming that the intermediate point 61 that bisects the swing trajectory (the arc centered on the user estimated position 60) is the front of the user. Calculate as direction 62.

  The key side azimuth sensor 28 outputs a voltage (signal) corresponding to the azimuth to which it is directed to the microcomputer 23. Based on the voltage (signal) from the key side azimuth sensor 28, the microcomputer 23 calculates which direction the user direction estimation direction 62 of the electronic key 2 is oriented, that is, the user direction estimation azimuth. Then, the microcomputer 23 transmits the information on the estimated user orientation included in the open door request signal or the closed door request signal transmitted through the swing operation in the state where the unlock switch 26 or the lock switch 27 is operated. .

  The in-vehicle control unit 33 calculates the direction of the traveling direction of the vehicle based on the voltage (signal) from the vehicle side direction sensor 35. The in-vehicle control unit 33 can determine the orientation direction of the user with respect to the vehicle based on the calculated vehicle orientation and user orientation estimation orientation information. As shown in FIG. 10, the orientation direction of the user with respect to the vehicle can be omnidirectional toward the center of the vehicle so as to surround the outer periphery of the vehicle. The in-vehicle control unit 33 restricts the slide door 6 that can be operated depending on which direction the user is directed with respect to the vehicle.

  That is, in FIG. 10, a first allowable range 55 is formed on the right side of the vehicle, which is configured by the direction of the user in the direction indicated by the hatched arrow 51 in FIG. 10 facing the right slide door 6R. Is formed with a second permissible range 56 configured in the direction of the user in the direction indicated by the white arrow 52 in FIG. 10 facing the left sliding door 6L. Specifically, the first tolerance range 55 and the second tolerance range 56 are formed in a fan shape on the right side and the left side with respect to the vehicle, and belong to both the first tolerance range 55 and the second tolerance range 56 in the longitudinal direction of the vehicle. There are no areas. The sliding door 6 to be operated by the user can be determined based on which of the first allowable range 55 and the second allowable range 56 the user's orientation direction belongs to. For example, when the direction of the user belongs to the first allowable range 55, the operation target is limited to the right slide door 6R. That is, when the user direction is the direction belonging to the first allowable range 55, a swing operation performed when the left slide door 6L is operated, for example, the swing switch is pressed to the right while the unlock switch 26 is pressed. Even if it is a case, the vehicle-mounted control part 33 makes the operation invalid and does not perform control which opens the left slide door 6L.

  Similarly, when the direction of the user belongs to the second allowable range 56, the operation target is limited to the left slide door 6L. That is, if the direction of the user belongs to the second allowable range 56, the swing operation performed when the right slide door 6R is operated, for example, the swing switch is pressed to the left while the unlock switch 26 is pressed. Even if it is a case, the vehicle-mounted control part 33 makes the operation invalid and does not perform control which opens the right slide door 6R.

  If the direction of the user does not belong to any of the first tolerance range 55 and the second tolerance range 56 formed between the first tolerance range 55 and the second tolerance range 56, the in-vehicle control unit 33 assumes that there is no intention to open and close the slide door 6 and invalidates the swing operation.

  Actually, the locus of the swinging operation of the electronic key 2 is not centered on the user estimated position 60, but an arc is drawn around the user's shoulder, elbow, etc., so the actual user orientation and user orientation estimation direction 62. As a result, although there may be a slight shift in the direction of the user, the shift is not so large as to affect the determination of the slide door 6 to be operated.

  As described above, the operation of the slide door 6 using the electronic key 2 when the user is not facing the target slide door 6 is invalidated. Accordingly, erroneous opening / closing of the slide door 6 due to a wrong swing direction is prevented. In addition, when the slide door 6 is operated, the user is requested to face the slide door 6 to be operated, so that the slide door 6 which is not intended by the user is prevented from being opened and closed, and the security is improved.

As described above, according to the embodiment described above, the following effects can be obtained.
(9) The direction to the intermediate point 61 of the trajectory of the swing operation from the user estimated position 60 is set as a user direction estimated direction 62 which is a direction estimated that the user is facing. In a state in which the user orientation estimation direction 62 faces the slide door 6 related to the operation target, the opening / closing of the slide door 6 based on the swing operation of the electronic key 2 is enabled, and the user orientation estimation direction 62 is the slide related to the operation target. When the door 6 is not facing, the opening / closing of the sliding door 6 based on the swinging operation of the electronic key 2 is invalidated. Thereby, opening and closing of the sliding door 6 which a user does not intend is suppressed.

(Fourth embodiment)
Hereinafter, a fourth embodiment in which the present invention is embodied in an electronic key system will be described. The electronic key system of this embodiment is different from the second embodiment in that various sliding door request signals are transmitted by the switch operation of the electronic key 2. Hereinafter, the difference from the second embodiment will be mainly described. In addition, the electronic key system 1 of this embodiment is equipped with the structure substantially the same as the electronic key system 1 of 2nd Embodiment shown in FIG.

  In the present embodiment, various slide door request signals are not transmitted by the swing operation. Accordingly, the determination (S103, S104) of the acceleration sensor 21 and the presence / absence of a swing operation based on the detection result is omitted. Further, as indicated by a broken line in FIG. 1, the electronic key 2 is provided with an opening / closing request switch 29. The opening / closing request switch 29 includes an open right door request switch 29a, a closed right door request switch 29b, an open left door request switch 29c, and a closed left door request switch 29d. When each of the switches 29a to 29d is pushed, an operation signal to that effect is output to the microcomputer 23.

  When the microcomputer 23 receives the operation signal from the open right door request switch 29a, the microcomputer 23 transmits an open right door request signal via the transmission circuit 24 and the transmission antenna 25. Hereinafter, similarly, when the microcomputer 23 receives an operation signal from the closed right door request switch 29b, the microcomputer 23 transmits a closed right door request signal via the transmission circuit 24 and the transmission antenna 25. When the microcomputer 23 receives an operation signal from the open left door request switch 29 c, the microcomputer 23 transmits an open left door request signal via the transmission circuit 24 and the transmission antenna 25. When the microcomputer 23 receives an operation signal from the closed left door request switch 29d, the microcomputer 23 transmits a closed left door request signal via the transmission circuit 24 and the transmission antenna 25.

  Similarly to the second embodiment, the in-vehicle controller 33 shifts to the panic detection mode when receiving various sliding door request signals. When receiving the various slide door request signals based on the operation of the opening / closing request switch 29 in the panic detection mode, the in-vehicle control unit 33 reverses the moving direction of the slide door 6. Similarly to the second embodiment, even when either the unlock switch 26 or the lock switch 27 is operated in the panic detection mode, the currently moving slide door is reversed.

As described above, according to the embodiment described above, the following effects can be obtained.
(10) By operating the opening / closing request switch 29, the slide door 6 moves in the opening / closing direction. In the panic detection mode during the movement of the slide door 6, any one of the opening / closing request switch 29, the unlock switch 26, and the lock switch 27 is operated, so that the moving direction of the slide door 6 is reversed.

  As described above, as the number of switches in the electronic key 2 increases, the ratio of the switches on the surface of the electronic key 2 increases. For this reason, the switch operation of the electronic key 2 can be performed more quickly.

(Fifth embodiment)
A fifth embodiment in which the present invention is embodied in an electronic key system will be described below with reference to FIG. The electronic key system of this embodiment is different from the first embodiment in that the electronic key system shifts to the panic detection mode on the electronic key side. Hereinafter, a description will be given focusing on differences from the first embodiment.

  When the vehicle-mounted control unit 33 receives a new window closing request signal or window closing request signal while the vehicle window is moving, the in-vehicle control unit 33 gives priority to this signal before the vehicle window is fully closed or fully opened. Reverse the direction of movement.

  The processing operation of the microcomputer 23 will be described below with reference to the flowchart of FIG. Note that the processing from step S201 to S205 is executed in the same manner as steps S101 to S105 in FIG. 5 in the first embodiment.

  When the window opening request signal or the window closing request signal is transmitted in step S205, the operation shifts to the panic detection mode. In this panic detection mode, it is determined whether or not the time from the start of the mode has passed the second set time T2 (S206). If it is determined that the second set time T2 has not elapsed (NO in S206), it is determined whether or not the lock switch 27 has been operated through the presence or absence of the operation signal S1 (S207). When it is determined that the lock switch 27 has not been operated (NO in S207), it is determined whether or not the unlock switch 26 has been operated through the presence or absence of the operation signal Su (S208). When it is determined that the unlock switch 26 has not been operated (NO in S208), it is again determined whether or not the second set time T2 has elapsed since the start of the panic detection mode (S206). That is, whether or not the unlock switch 26 or the lock switch 27 is operated is monitored over the second set time T2.

  When it is determined that the lock switch 27 or the unlock switch 26 is operated (YES in S207 or YES in S208), a window opening request signal or a window closing request signal that is different from the signal transmitted in Step S205 is transmitted ( S209). Specifically, if a window opening request signal is transmitted in step S205, a window closing request signal is transmitted in step S209. If a window opening request signal is transmitted in step S205, the window opening request signal is transmitted in step S209. A window request signal is transmitted. Then, the flowchart is ended.

  Further, when it is determined that the second set time T2 has elapsed since the start of the panic detection mode (YES in S206), the flowchart is ended without transmitting a window opening request signal or the like. Note that the signal transmitted in step S209 corresponds to a signal requesting cancellation of the control being executed.

As described above, according to the embodiment described above, the following effects can be obtained.
(11) The electronic key 2 (microcomputer 23) shifts to the panic detection mode. For this reason, what is necessary is just to perform the process similar to the former about the vehicle-mounted control part 33. FIG. Specifically, the in-vehicle control unit 33 controls the opening / closing of the window according to the window opening request signal or the window closing request signal from the electronic key 2.

In addition, the said embodiment can be implemented with the following forms which changed this suitably.
In each of the above embodiments, the moving direction of the window or the like can be reversed only once per panic detection mode. However, the slide door 6 may be reversible every time the unlock switch 26 or the like is operated in the panic detection mode. In this case, in the first to fourth embodiments, after the in-vehicle control unit 33 reverses the moving direction of the window (S109), does the time from the start of the mode again pass the second set time T2? It is determined whether or not (S107). In the fifth embodiment, after the window closing request signal or the window opening request signal is transmitted (S209), it is determined again whether the time from the start of the panic detection mode has passed the second set time T2. (S206).

  In the first embodiment, the window can be opened / closed by swinging the electronic key 2, and in the second embodiment, the sliding door can be opened / closed by swinging the electronic key 2. However, the combination of both the above embodiments may allow the sliding door and the window to be opened and closed by swinging the electronic key 2. Also in this configuration, the swing operation direction of the electronic key 2 related to the window is the vertical direction, and the swing operation direction of the electronic key 2 related to the slide door is the horizontal direction, so the swing operation directions do not overlap.

  In the fourth embodiment, in the panic detection mode, when any of various slide door request signals, lock request signals, and unlock request signals is received, the slide door is inverted. However, in the panic detection mode, the slide door may be reversed only when various slide door request signals are received.

  In the fifth embodiment, when the window closing request signal is transmitted in step S205 in FIG. 11, the window opening request signal is transmitted in step S209 in the panic detection mode. However, an inversion request signal may be transmitted in step S209. When the in-vehicle control unit 33 receives the inversion request signal through the receiving circuit 32, the in-vehicle control unit 33 inverts the moving direction of the currently executing window. According to this configuration, it is sufficient to always transmit the same inversion request signal in step S209.

  In the first to third and fifth embodiments, the presence / absence of the swing operation is determined for the acceleration on each of the X axis, the Y axis, and the Z axis. However, the acceleration is not limited to three axes, and may be performed for acceleration on at least one of the X, Y, and Z axes.

  -In 1st-4th embodiment, the vehicle-mounted control part 33 reversed the sliding door etc., if the lock request signal or the unlock request signal was received in panic detection mode. However, the in-vehicle control unit 33 may stop the moving slide door or the like at that position without inverting the slide door or the like. As a result, the object can be prevented from being caught by a slide door or the like as in the above embodiment.

  In the fifth embodiment, when the microcomputer 23 determines that the unlock switch 26 or the lock switch 27 is operated in the panic detection mode, the microcomputer 23 transmits a cancel signal for requesting stop of the control currently being executed. May be. In this case, the vehicle-mounted control unit 33 stops the movement of the slide door or the like when receiving the cancel signal.

  In each of the above embodiments, the window or slide door corresponding to the opening / closing body can be opened / closed by swinging while pressing the lock switch 27 or the unlock switch 26. However, the opening / closing body that can be operated by the swing operation is not limited to these, and may be a door mirror or a roof window. For example, in the case of a door mirror, when the unlock switch 26 or the lock switch 27 is operated in the panic detection mode, the deployed door mirror moves in the retracted direction. Thereby, it is suppressed that a door mirror contacts an object.

  In each of the above embodiments, the window or the like can be opened and closed by a swing operation, but may be a tilt operation. Here, the tilting operation of the electronic key 2 refers to an operation of tilting the electronic key 2 held by the user by moving the wrist or the like. As the detection means for detecting the tilt operation, an angular velocity sensor for detecting the angular velocity is suitable.

  In each of the above embodiments, in the panic detection mode, the window or the like can be moved in any of the opening and closing directions by a switch operation. However, in the panic detection mode, the moving direction of the window or the like accompanying the switch operation may be limited from the closing direction to the opening direction. This is when there is a possibility that an object may be caught in the window, etc., when the window, etc. is moving from the opening direction to the closing direction, which is prevented by moving the window, etc. from the closing direction to the opening direction. Because it can. In this configuration, the moving direction of the window in step S109 in FIG. 5 is only the opening direction from the closing direction. Further, only the window opening request signal is transmitted in S209 in FIG.

  In the above embodiments, the unlock switch 26 or the lock switch 27 may be omitted, and a new inversion switch may be provided. In this case, for example, an unlock request signal or a lock request signal is transmitted from the electronic key 2 by performing a swing operation of the first pattern. Further, various sliding door request signals are transmitted from the electronic key 2 by performing the swing operation of the second pattern. The first and second patterns are patterns that draw a locus such as a circle or a triangle, for example. After various sliding door request signals are transmitted, the mode is shifted to the panic detection mode. In this panic detection mode, when the reversing switch of the electronic key 2 is operated, a radio signal for requesting reversal of the window or the like is transmitted from the electronic key 2. Thereby, the moving direction of the window or the like is reversed.

  -The structure which transfers to the panic detection mode in the electronic key 2 in 5th Embodiment is applicable also in the structure which can open and close the sliding door in the said 2nd-4th embodiment. When the second and third embodiments are applied, the fifth embodiment is the same except that the object to be controlled in the signals transmitted in steps S205 and S209 in the flowchart of FIG. 11 differs between the window and the sliding door. The process is performed in the same manner as. In addition, when the fourth embodiment is applied, it is determined whether or not the opening / closing request switch 29 is operated after steps S207 and S208, and various sliding door request signals are transmitted when it is determined that there is any operation. The The slide door is inverted by this signal.

In each of the above embodiments, the swing operation direction when the lock switch 27 or the like is operated matches the moving direction of the window or the like. However, this may be different.
In each of the above embodiments, the unlock switch 26 and the lock switch 27 are provided separately, but may be configured as a single locking / unlocking switch. In this case, every time the lock / unlock switch is operated, the lock request signal and the unlock request signal are alternately transmitted from the electronic key 2.

-In each above-mentioned embodiment, although the control object was a vehicle, it may be not only a vehicle but a house.
Next, the technical idea that can be grasped from the embodiment will be described together with the effects.

Electronic key system that reverses the direction of movement.

  According to this configuration, the opening / closing body moves through the operation of the opening / closing request switch. For example, when the opening / closing body is moving in the closing direction, the user operates the opening / closing request switch when the user notices that an object contacts the opening / closing body. Thereby, the moving direction of the opening / closing body is reversed, and the movement in the opening direction is started. Thereby, it is suppressed that an object contacts an opening-and-closing body.
