When the motion operating unit for operating the motion operation target door provided on the communication partner and the manual operation for operating the door of the communication partner are detected based on the determination of the motion operation determination unit, the motion operating unit It is provided with a limiting unit that limits the execution of the operation of the motion operation target door by the above.

According to this configuration, in the situation where the user manually operates, it is natural that both hands are not closed, and there is a high possibility that the motion operation is not necessary. Therefore, on the premise of this, when a situation in which the user manually operates is detected, the execution of the door operation by the motion operating unit is restricted. Therefore, it is possible to suppress the occurrence of door malfunction due to motion operation.

In the door operation control system, it is preferable that the manual operation is a state in which another door other than the motion operation target door is opened.
According to this configuration, the situation where the door other than the motion operation target door is open is considered to be the situation where the user manually operates the door and both hands are not closed. Therefore, it is possible to limit the motion operation in a situation where there is a high possibility that the motion operation is not required. This contributes to suppressing the occurrence of door malfunction due to motion operation.

In the door operation control system, it is preferable that the electronic key or the communication partner includes an operation unit that is operated when operating the door, and the manual operation is that the operation unit is operated.

According to this configuration, the situation in which the user operates the operation unit seems to be a situation in which both hands are not closed. Therefore, it is possible to limit the motion operation in a situation where there is a high possibility that the motion operation is not required. This contributes to suppressing the occurrence of door malfunction due to motion operation.

Hereinafter, an embodiment of the door operation control system will be described with reference to FIGS. 1 to 3.
As shown in FIG. 1, the vehicle 1 includes an electronic key system 3 that wirelessly collates an ID with an electronic key 2. The electronic key system 3 of this example is a key operation-free system that executes ID verification by narrow-range radio (communication distance is several meters) triggered by communication from the vehicle 1. Hereinafter, ID collation by the key operation free system will be referred to as "smart collation", and the communication will be referred to as "smart communication".

The vehicle 1 includes a collation ECU (Electronic Control Unit) 4 that performs ID collation (smart collation), a body ECU 5 that manages the power supply of in-vehicle electrical components, and a power slide door that controls the operation of the power slide door (slide door 9). It includes an ECU 6 and an engine ECU 8 that controls the engine 7. These ECUs are connected through a communication line 10 in the vehicle. The communication line 10 is composed of, for example, CAN (Control Area Network) or LIN (Local Interconnect Network). The electronic key ID of the electronic key 2 registered in the vehicle 1 is written and stored in the memory 11 of the collation ECU 4.

The body ECU 5 of the vehicle 1 controls the operation of the door lock mechanism 13 as a mechanical portion for locking and unlocking the manual door 12 such as the driver's door and the passenger's door. The body ECU 5 detects whether the manual door 12 is open or closed by using an output signal of a door courtesy (not shown) provided in the vehicle 1.

The vehicle 1 includes an outdoor transmitter 14 that transmits radio waves to the outside, an indoor transmitter 15 that transmits radio waves indoors, and a vehicle receiver 16 that receives radio waves in the vehicle 1. The outdoor transmitter 14 and the indoor transmitter 15 transmit, for example, radio waves in the LF (Low Frequency) band. The vehicle receiver 16 receives, for example, radio waves in the UHF (Ultra High Frequency) band.

The electronic key 2 includes a key control unit 20 that controls the operation of the electronic key 2, a receiving unit 21 that receives radio waves in the electronic key 2, and a transmitting unit 22 that transmits radio waves in the electronic key 2. An electronic key ID, which is a unique ID of the electronic key 2, is written and stored in the memory 23 of the key control unit 20. The receiving unit 21 receives, for example, an LF radio wave. The transmission unit 22 transmits, for example, UHF radio waves.

The manual door 12 is provided with an outside door handle 25 that is operated when the manual door 12 is opened and closed. The vehicle exterior door handle 25 is provided with, for example, a touch sensor 25a, and a gripping operation of the vehicle exterior door handle 25 when the manual door 12 is opened is detected. The door handle 25 outside the vehicle is provided with a door operation unit 26 that is operated when the manual door 12 is locked. The door operation unit 26 includes, for example, a press operation type lock button.

The electronic key 2 includes a key operation unit 27 that is operated when the manual door 12 is operated by remote control of the electronic key 2. The key operation unit 27 includes, for example, an unlock operation unit 28 that is operated when the manual door 12 is unlocked, a lock operation unit 29 that is operated when the manual door 12 is locked, and the like (see FIG. 2).

As shown in FIG. 2, the outdoor transmitter 14 forms an outdoor communication area Ea around the vehicle 1. The outdoor communication area Ea of this example illustrates three areas by the outdoor transmitter 14 provided on the driver's seat side, the passenger seat side, and the back door side, but the location of the outdoor transmitter 14 to be arranged is shown. And the number may be changed as appropriate according to the number. The indoor transmitter 15 forms an indoor communication area Eb in the entire interior of the vehicle 1. The outdoor transmitter 14 and the indoor transmitter 15 periodically transmit a wake signal in order to search for the electronic key 2, and cause a response (ac) to the reception of the wake signal to be returned from the electronic key 2.

When the electronic key 2 enters the outdoor communication area Ea and communication (outdoor smart communication) is established between the vehicle 1 and the electronic key 2, smart collation (outdoor smart collation) is started. The smart collation includes a vehicle code collation that authenticates a unique vehicle code possessed by the vehicle 1, a challenge response authentication that uses an encryption key, and an electronic key ID collation that authenticates an electronic key ID. When the collation ECU 4 confirms that all of these collations and authentications are established with the electronic key 2 in the outdoor communication area Ea, the collation ECU 4 considers the outdoor smart collation to be established, and performs the manual door 12 (sliding door 9). Allow or execute the lock. In this example, locking / unlocking of the manual door 12 is permitted by the establishment of ID verification, and when the outside door handle 25 or the door operation unit 26 of the manual door 12 is operated in this state, the manual door is locked / unlocked. .. When the lock operation unit 29 or the unlock operation unit 28 of the electronic key 2 is operated, a lock request or unlock request is transmitted from the electronic key 2 to the vehicle 1, and the manual door 12 is locked / unlocked.

When the electronic key 2 enters the indoor communication area Eb and communication (indoor smart communication) is established, the collation ECU 4 executes smart collation (indoor smart collation) similar to that in the case of outdoors. When the collation ECU 4 confirms that the indoor smart collation is established, the collation ECU 4 permits the transition of the vehicle power supply by the operation of the engine switch 30.

The communication partner of the electronic key 2 (vehicle 1 in this example) is a power slide door ECU 6 that controls the operation of a door that can be automatically opened and closed (slide door 9 in this example), and a drive source for automatic opening and closing of the slide door 9. It is provided with a power slide door motor 34. The power slide door ECU 6 controls the power slide door motor 34 based on, for example, the operation of the vehicle exterior door handle 35a provided on the slide door 9 or the power slide door switch 35b provided on the driver's seat. The slide door 9 is automatically opened and closed.

Specifically, when the slide door 9 is in the closed state, for example, when the door handle 35a outside the vehicle, the power slide door switch 35b, or the like is used to open the slide door 9, the power slide door ECU 6 rotates the power slide door motor 34 in one direction. As a result, the slide door 9 is automatically opened. Further, when the slide door 9 is in the closed state, for example, when the door handle 35a outside the vehicle, the power slide door switch 35b, or the like is used to close the slide door 9, the power slide door ECU 6 rotates the power slide door motor 34 in the other direction. The slide door 9 is automatically closed.

The door operation control system 31 is a door (in this example, a sliding door 9) without the user touching the electronic key 2 and the communication partner (vehicle 1) by a predetermined movement (motion operation) of the user holding the electronic key 2. It has a motion operation function to operate. The motion operation function of this example automatically opens the closed slide door 9 by motion operation. Further, the series of opening operations by the motion operation includes unlocking the vehicle door (sliding door 9) when the vehicle door (sliding door 9) is locked. In the case of this example, the sliding door 9 is the motion operation target door, and the manual door 12 is not the motion operation target door.

The electronic key 2 includes a displacement detection unit 36 that detects the movement of the electronic key 2. The displacement detection unit 36 outputs a detection signal Sa corresponding to the movement generated in the electronic key 2 to the key control unit 20. The displacement detection unit 36 is preferably, for example, an acceleration sensor, an angular velocity sensor, a vibration sensor, or the like. The displacement detection unit 36 monitors the movement generated in the electronic key 2 by detecting the movement in the three axes of the X-axis, the Y-axis, and the Z-axis, for example. In this example, the displacement detection unit 36 enables the detection function when the electronic key 2 moves, and disables the detection function when there is no movement.

The door operation control system 31 includes a motion operation determination unit 37 that determines whether or not a motion operation has occurred based on the output of the displacement detection unit 36. The motion operation determination unit 37 is provided in the key control unit 20. The motion operation determination unit 37 of this example checks, for example, whether or not the detection voltage (output voltage) of the displacement detection unit 36 as the detection signal Sa changes according to the specified movement, and thereby the electronic key 2 Determines the presence or absence of specified movements that may occur in. It is preferable that the specified movement is, for example, a tap on both heels from an upright position, with both feet standing on the toes and returning to the original position (putting the heel on the ground). When the motion operation determination unit 37 determines that the specified movement has occurred in the electronic key 2, the motion operation determination unit 37 transmits an operation request Sc requesting the start of operation of the slide door 9 from the electronic key 2. Upon receiving this operation request Sc, the vehicle 1 performs control according to the operation request Sc (in this example, the slide door 9 is opened) on the premise that ID collation is established.

The door operation control system 31 includes a motion operation unit 33 that operates the slide door 9 provided in the vehicle 1 based on the determination of the motion operation determination unit 37. In this example, the power slide door ECU 6 corresponds to the motion operating unit 33. When the vehicle 1 receives the operation request Sc based on the determination of the motion operation determination unit 37, the power slide door ECU 6 executes the opening operation of the slide door 9.

The door operation control system 31 includes a limiting unit 38 that limits the execution of the operation of the motion operation target door by the motion operation when the manual operation related to the operation of the door is detected. In this example, the limiting unit 38 is provided in the motion operating unit 33 (power slide door ECU 6). In this example, the manual operation related to the operation of the door is the opening operation of the manual door 12. Specifically, when the body ECU 5 detects that the manual door 12 is in the open state, the limiting unit 38 prohibits the opening operation of the slide door 9.

The door operation control system 31 includes a key position determination unit 32 for determining whether the electronic key 2 is indoors or outdoors. The key position determination unit 32 is provided in the collation ECU 4. The key position determination unit 32 of this example recognizes the position of the electronic key 2 through smart collation communication performed between the electronic key 2 and the collation ECU 4. In the case of this example, the key position determination unit 32 recognizes whether the electronic key 2 is located outdoors or indoors by confirming whether or not the smart collation outside the vehicle and the smart collation inside the vehicle are established. The limiting unit 38 prohibits the operation of the motion operation target door (sliding door 9) by the motion operation when the manual operation is detected under the condition that the electronic key 2 is determined to be located outside the room.

Next, the operation and effect of the door operation control system 31 will be described with reference to FIGS. 2 and 3.
As shown in FIG. 2, a case where a user holding the electronic key 2 enters the outdoor communication area Ea and performs a predetermined movement (tap both heels in this example) in order to perform a motion operation will be described. Here, it is assumed that all the doors of the vehicle 1 are locked and closed.

As shown in FIG. 3, in step S101, when the electronic key 2 enters the outdoor communication area Ea and the outdoor smart collation is established between the electronic key 2 and the vehicle 1, the key position determination unit 32 uses the electronic key. 2 is determined to be in the outdoor communication area Ea. When the key position determination unit 32 determines that the electronic key 2 exists in the outdoor communication area Ea, the key position determination unit 32 proceeds to step S102.

In step S102, the limiting unit 38 determines whether the manual door 12 monitored by the body ECU 5 is in the closed state. In the case of this example, the body ECU 5 detects the opening / closing of the manual door 12 based on the detection signal of the door courtesy switch. The body ECU 5 outputs a door closing signal when the manual door 12 is closed and a door opening signal when the manual door 12 is open to the power slide door ECU 6. Therefore, if the door closing signal is input from the body ECU 5, the limiting unit 38 recognizes that the manual door 12 is in the closed state, and proceeds to step S103. On the other hand, if the door open signal is input from the body ECU 5, the limiting unit 38 recognizes that the manual door 12 is in the open state, and proceeds to step S104.

In step S103, the limiting unit 38 does not prohibit the motion operation function of the vehicle 1 but enables it. As a result, when the user performs a motion operation, the user can shift the slide door 9 to the open state without touching the electronic key 2 and the vehicle 1 by hand.

By the way, in the situation where the manual door 12 (for example, the door of the driver's seat) is open, it is considered that the opening operation of the slide door 9 by the motion operation is not required. This is because there is a high possibility that both hands of the user are not blocked if the manual door 12 can be operated. Therefore, there is no inconvenience even if the motion operation function is prohibited. Further, when the motion operation function is prohibited, even if the user unintentionally performs the same operation as the motion operation, the slide door 9 does not start the opening operation by the same operation. Therefore, when the manual door 12 is open, the motion operation function is prohibited, and priority is given to preventing unnecessary opening operation of the slide door 9.

In step S104, when the limiting unit 38 recognizes that the manual door 12 is in the open state, the limiting unit 38 prohibits the opening operation of the slide door 9 by motion operation. Therefore, even if the user makes a movement similar to the specified movement (both heel taps) after opening the manual door 12, the slide door 9 is not opened. Therefore, it is possible to suppress the malfunction of the door due to the motion operation.

As described above, in this example, the limiting unit 38 that limits the motion operation function when the manual operation for operating the door is detected is provided. According to this configuration, in the situation where the user manually operates, it is natural that both hands are not closed, and there is a high possibility that the motion operation is not necessary. Therefore, on the premise of this, when the situation where the user manually operates is detected, the motion operation function is restricted. Therefore, it is possible to suppress the occurrence of door malfunction due to motion operation.

Further, in this example, the manual operation for limiting the motion operation function is that the manual door 12 which is not the motion operation target door is in the open state. According to this configuration, the situation where the manual door 12 which is not the motion operation target door is open is considered to be the situation where the user manually operates the manual door 12 and both hands are not closed. Therefore, it is possible to limit the motion operation function in a situation where there is a high possibility that the motion operation is not required. This contributes to suppressing the occurrence of door malfunction due to motion operation.

Further, in this example, a key position determination unit 32 for determining whether the electronic key 2 is located indoors or outdoors is provided during ID collation communication, and the limiting unit 38 determines that the electronic key 2 is outdoors. The motion operation function is restricted when manual operation is detected under the above circumstances. According to this configuration, even if the user makes a movement similar to a predetermined movement outdoors, the motion operation function can be restricted. In particular, when the user is outdoors, there is a high possibility that the movement will be similar to that of a motion operation. Therefore, in this respect, it contributes to the suppression of the malfunction of the door due to the motion operation.

In addition, this embodiment can be changed and carried out as follows. This embodiment and the following modified examples can be combined and implemented within a technically consistent range.
-In the present embodiment, the operation corresponding to the manual operation is not limited to the opening operation of the manual door 12. For example, as shown in FIG. 4, the manual operation may be the operation of the electronic key 2 or the operation unit 24 provided on the communication partner (vehicle 1). In the case of this example, the operation of the unlock operation unit 28, the operation of the lock operation unit 29, the contact operation of the manual door 12 with the outside door handle 25, and the operation of the door operation unit 26 correspond to the operation of the operation unit 24. , And the operation of the outside door handle 35a of the slide door 9. Hereinafter, the case where the unlock operation unit 28 and the door handle 25 outside the vehicle are touched will be described with reference to FIGS. 5 and 6.

As shown in FIG. 5, when the key operation unit 27 (unlock operation unit 28) provided on the electronic key 2 is operated, an operation request (unlocking request) Sc including the electronic key ID is issued from the electronic key 2. It is transmitted to the vehicle 1. When the vehicle receiver 16 of the vehicle 1 receives the operation request Sc, the collation ECU 4 collates the electronic key ID included in the operation request Sc. When the ID collation is established, the collation ECU 4 sends a signal to the body ECU 5 that the unlock operation unit 28 has been operated, and the body ECU 5 unlocks the door lock mechanism 13. At the same time, the collation ECU 4 sends a signal to the power slide door ECU 6 to the effect that the unlock operation unit 28 has been operated. The limiting unit 38 to which this signal is input prohibits the power slide door ECU 6 from operating the slide door 9.

According to this configuration, in the situation where the user operates the operation unit 24 (unlock operation unit 28), it seems that both hands are not closed. Therefore, it is possible to limit the motion operation function in a situation where there is a high possibility that the motion operation is not required. This contributes to suppressing the occurrence of door malfunction due to motion operation.

Further, as shown in FIG. 6, on the premise that smart collation (outdoor smart collation) is established, when the touch sensor 25a of the vehicle exterior door handle 25 of the manual door 12 detects contact, the contact detection signal St is the body. It is transmitted to the ECU 5. When the contact detection signal St is input, the body ECU 5 causes the door lock mechanism 13 to unlock the manual door 12, and also causes the power slide door ECU 6 to transmit a signal to the effect that the unlock is executed by detecting the contact of the outside door handle 25. Send. The limiting unit 38 that has input this signal prohibits the power slide door ECU 6 from operating the slide door 9. This configuration also contributes to suppressing the occurrence of door malfunction due to motion operation.

As described above, the manual operation in the present embodiment may be an operation performed by the user by touching the electronic key 2 or the communication partner (vehicle 1) by hand.
-In the present embodiment, the motion operation may also enable the sliding door 9 to be closed.

-In the present embodiment, it is not necessary to confirm all the ID communications until the ID collation is established in the monitoring of whether or not the electronic key 2 is located in the outdoor communication area Ea. For example, it may be determined whether or not the electronic key 2 is in the outdoor communication area Ea depending on whether or not only a predetermined response such as an ac can be received from the electronic key 2.

-In the present embodiment, the electronic key system 3 is not limited to a system configuration in which LF antennas (outdoor transmitter 14 and indoor transmitter 15) are arranged indoors and outdoors. For example, LF antennas may be arranged on the left and right sides of the vehicle body, and the indoor / outdoor state of the electronic key 2 may be determined by confirming the combination of the responses of the electronic key 2 to the radio waves transmitted from these antennas.

-In the present embodiment, it may be omitted that the electronic key 2 is in the outdoor communication area Ea due to the condition of prohibiting the motion operation function. That is, the position determination of the electronic key 2 can be omitted in order to prohibit the motion operation function.

-In the present embodiment, the prescribed movement of the motion operation is not limited to both heel taps. For example, it may be a bending / stretching operation of a user who possesses an electronic key. Further, the motion is not limited to one, and may be a combination of a plurality of motions such as bending / stretching → stationary → bending / stretching.

-In the present embodiment, the detection signal Sa of the displacement detection unit 36 may be transmitted from the electronic key 2 to the vehicle 1 as it is, and the movement may be determined on the vehicle 1 side. That is, the motion operation determination unit 37 may be provided on the vehicle 1 side.

-In the present embodiment, the function of the vehicle 1 assigned to the key operation unit 27 is not limited to this example. For example, the slide door 9 may be opened and closed.
-In the present embodiment, various members such as a motion sensor, a vibration sensor, and a gyro sensor can be applied to the displacement detection unit 36.

-In the present embodiment, the limiting unit 38 may function to limit a part of the motion operation when the manual operation is detected. For example, in determining that a predetermined motion has occurred, the threshold value of the determination may be increased or the motion detection may be slowed down so as to make it difficult to make an affirmative determination.

-In the present embodiment, the mechanism for limiting the motion operation function is not limited to prohibiting the motion operating unit 33 (power slide door ECU 6) from operating the slide door 9. For example, the displacement detection unit 36 may be prohibited from detecting the movement, or the motion operation determination unit 37 may be prohibited from determining the movement. Therefore, the limiting unit 38 is not limited to being provided on the vehicle 1 (power slide door ECU 6), and may be provided on the electronic key 2 side.

-In the present embodiment, the door to be operated by the motion operation is not limited to the sliding door 9. For example, it can be changed to another door such as a luggage door or a back door.
-In the present embodiment, the displacement detection unit 36 enables the detection function when the electronic key 2 receives the wake signal from the vehicle 1, and detects when the electronic key 2 is away from the vehicle 1 and no signal is received. The function may be disabled. Further, although the detection function may always be enabled, it is preferable that the detection function is disabled under the specified conditions in order to suppress the power consumption of the electronic key 2.

-In the present embodiment, the communication partner is not limited to the vehicle 1, but can be changed to another device or device.
-In the present embodiment, the electronic key system 3 may be a system using a high-performance mobile phone or the like as the electronic key 2.

-In the present embodiment, the band of wireless communication between the vehicle 1 and the electronic key 2 used for ID verification is not particularly limited. Further, the communication method may be changed to various modes.
