The switch for registration may be a dedicated switch, or may be used as an existing switch by long-pressing an existing switch or performing a combination operation of a plurality of switches.

The predetermined operation is one of the following.
-Automatic door opening (unlocking and opening).
・ Door unlocking only.
This configuration is “the predetermined operation is either a door opening operation or an unlocking operation of the vehicle door”. With this configuration, it is possible to save the user's operation when the door is difficult to operate, such as when holding a baggage in both hands. In addition, the user's convenience can be ensured to some extent only by performing the unlocking operation.

  The vehicle 10 includes hinged doors 11 and 12 corresponding to the front seats, and slide type doors (hereinafter referred to as “sliding doors”) 13 and 14 corresponding to the rear seats. The slide doors 13 and 14 (vehicle doors of the present invention) are provided with slide door drive units 7c and 7d using a motor as a drive source. Open and close. The vehicle 10 also includes a flip-up type rear door 15. The rear door 15 is also provided with a rear door drive unit 8 using a motor as a drive source, and automatically opens and closes the rear door 15 in accordance with an open / close signal from the electronic key ECU 4.

  The vehicle-side unit is provided in the vehicle interior, with the electronic key ECU 4 and the vehicle exterior transmitters 2a to 2e (vehicle-side transmitters of the present invention) provided in the doors 11 to 15 connected to the electronic key ECU 4. In-vehicle transmitter 2f, receiver 3 provided in the vehicle interior (vehicle-side receiving unit of the present invention), door lock control units 5a to 5e (operation control unit of the present invention) provided in the respective doors 11 to 15, It includes sliding door drive units 7c and 7d (operation control unit of the present invention).

  The vehicle interior transmitter (generic name for 2a to 2e, the same applies hereinafter) and the vehicle interior transmitter 2f transmit a request signal based on a transmission instruction signal from the electronic key ECU 4. The reach distance of the request signal is set to about 0.7 to 1.0 m, for example. When the vehicle 10 is parked, a detection area corresponding to the arrival distance of the request signal is formed around each of the doors 11 to 15 so that it can be detected which door the holder of the portable device 1 has approached. The detection area by the vehicle interior transmitter 2f is set so as to cover the vehicle interior, and detects whether the portable device 1 is in the vehicle interior.

  The receiver 3 is in a state where it can receive a response signal from the portable device 1 in synchronization with the output timing of the transmission instruction signal to the vehicle interior transmitter and vehicle interior transmitter 2f. The response signal received by the receiver 3 is output to the electronic key ECU 4. The electronic key ECU 4 collates the ID code included in the received response signal with the master code stored by itself, and based on the collation result, should the door lock / unlock operation be controlled, etc. Judgment is made. Furthermore, it is determined whether or not a predetermined operation needs to be performed on the slide doors 13 and 14 and the rear door 15 depending on whether or not the reservation information is included in the response signal.

  The door lock control units 5a to 5e lock or unlock the doors 11 to 15 based on an instruction signal from the electronic key ECU 4, but the holder of the portable device 1 touches the door handle. To enter the unlockable standby state.

  Touch sensors 6a1 to 6e1 are provided on the door handles 6a to 6e of the doors 11 to 15 of the vehicle 10, and the holder of the portable device 1 touches the door handles 6a to 6e and performs a predetermined operation. Is detected. The door handles 6a to 6e are also provided with door lock switches 6a2 to 6e2 that are configured as push switches and lock the doors 11 to 15. Further, the door handles 6a to 6e also serve as antennas for the above-described vehicle interior transmitters 2a to 2e.

  With reference to FIG. 2, a reservation operation control process that is repeatedly executed by the control unit 2 at a predetermined timing will be described. First, regular collation is performed (S11). That is, when the engine of the vehicle 10 is stopped and each of the doors 11 to 15 is parked in a locked state, the outside transmitters 2a to 2e are instructed to transmit request signals every predetermined time, and It is confirmed whether or not the user who owns the machine 1 has approached the vehicle 10.

  When the response signal is not received, that is, when the portable device 1 is not present in any of the detection areas, the response signal may be waited for a predetermined time, or this process may be temporarily terminated.

  Next, when a response signal is received, it is determined whether or not the ID code included in the response signal satisfies a predetermined relationship, for example, matches the master code stored in the electronic key ECU 4 (ID code verification) Determination of success / failure). When it is determined that ID code verification is not established (S12: No), this process is terminated.

  On the other hand, when collation of the ID code is established (S12: Yes), it is determined whether or not reservation information is included in the response signal. The reservation information is information for operating a predetermined sliding door (either 13 or 14) in advance (details will be described later). When the reservation information is not included (S13: No), this process ends.

On the other hand, when the reservation information is included (S13: Yes), one of the following is performed (S14).
An instruction signal is output from the electronic key ECU 4 to the corresponding door lock control unit and slide door drive unit so as to perform the predetermined operation of the slide door specified by the reservation information. At this time, a signal instructing deletion of the reservation information is transmitted to the portable device 1, and this process is terminated without executing the subsequent steps. This configuration is “when the operation control unit controls a predetermined operation, the portable device-side transmission unit transmits a reservation information erasure request signal for requesting deletion of the reservation information to the portable device”. This saves the user from having to delete the reservation information.
In addition to unlocking only the designated door, the door to be unlocked may also unlock the door on the same side as the designated door (door 11 when the sliding door 13 is designated). Then, all the doors may be unlocked.
Here, no operation is performed (a predetermined operation is executed after step S18).

  When no operation is performed in step S14, the position of the portable device 1 is specified (S15). The request signal includes a unique identification code set for each transmitter outside the vehicle interior, and the portable device 1 is configured to return a response signal including the identification code. Alternatively, the electronic key ECU 4 instructs the outdoor transmitter to transmit the request signals in a predetermined order. If any one of these is used, the electronic key ECU 4 can identify which portable device 1 has returned a response signal in response to a request signal from any vehicle interior transmitter. That is, it is possible to identify which door 11 to 15 is in the detection area of the portable device 1.

  Next, event collation is performed (S16). This is performed to determine whether or not the specified position of the portable device 1 matches the position specified in the reservation information. For example, the request signal is transmitted only from the vehicle exterior transmitter corresponding to the position specified by the reservation information. The request signal includes information indicating that the request target is only the portable device 1 (for example, the key ID of the portable device 1). When the response signal from the portable device 1 is not received within the predetermined time, or when the key ID included in the received response signal does not match the key ID included in the reservation information (S17: No), this process is terminated. To do.

On the other hand, when the response signal from the portable device 1 is received within the predetermined time and the key ID included in the response signal matches the key ID included in the reservation information (S17: Yes), any of the following (S18).
An instruction signal is output from the electronic key ECU 4 to the corresponding door lock control unit and slide door drive unit so as to perform the predetermined operation of the slide door specified by the reservation information. At this time, a signal instructing deletion of the reservation information is transmitted to the portable device 1, and this process is terminated without executing the subsequent steps.
Here, no operation is performed (the predetermined operation is executed in step S21).

  The above-described configuration is as follows: “The vehicle unit includes a position specifying unit that specifies the position of the portable device based on the state of communication with the portable device, and the operation control unit specifies the position of the portable device in the reservation information. When the vehicle door is within a predetermined range from the vehicle door, a predetermined operation is performed. With this configuration, for example, since the door automatically opens after the user approaches the door, it is possible to prevent rain or the like from falling even in bad weather. Further, it is possible to prevent a malicious person from entering the vehicle interior.

  When no operation is performed in step S18, event collation is performed again (S19). Here, a request signal similar to that in step S16 is transmitted at a predetermined period and timing such as 4 seconds in total at 500 msec intervals, for example. When the position of the portable device 1 changes, for example, when the ratio of the number of response signals received from the portable device 1 and the number of request signal transmissions to the portable device 1 falls below a predetermined value (for example, 80%) ( S20: No), this process ends.

  When no operation is performed in step S18, steps S16 to S18 need not be executed.

  On the other hand, when the position of the portable device 1 does not change (S20: Yes), the electronic key ECU 4 instructs the corresponding door lock control unit and the slide door drive unit to perform the predetermined operation of the slide door specified by the reservation information. A signal is output (S21).

  The above-described configuration is as follows: “The vehicle unit includes a position specifying unit that specifies the position of the portable device based on the state of communication with the portable device, and the operation control unit specifies the position of the portable device in the reservation information. When a predetermined period is within a predetermined range from the vehicle door, a predetermined operation is performed. With this configuration, when the user really wants to open the vehicle door, a predetermined operation can be performed.

  Finally, a signal for instructing deletion of the reservation information is transmitted to the portable device 1 (S22), and this process ends. When the portable device 1 receives a signal instructing deletion of reservation information, the portable device 1 deletes or invalidates the corresponding reservation information.

  In the process of the above-mentioned figure, only the door (only the door specified in the reservation information or all the doors may be unlocked) is unlocked in step S14 or S18, and the door specified in step S21 is automatically opened. You may do it.

The reservation information includes the following contents.
A key ID for identifying the portable device.
A door to be operated in a predetermined manner (one of the slide doors 13 and 14 or the rear door 15 may be included in the operation).
-Details of the predetermined operation (automatic door opening operation or unlocking operation).

  A plurality of reservation information may be registered, and the user may select one of them. When reservation information is newly registered, priority is given to the reservation information. Each reservation information is provided with an associated flag, and a flag corresponding to the selected reservation information is set. When the reservation information deletion instruction is received from the electronic key ECU 4, the flag is cleared.

  With reference to FIG. 3, the automatic door opening operation of the sliding door 13 is taken as an example (the same applies to the unlocking operation), and the positional relationship between the portable device 1 (that is, the user) and the vehicle 10 and the operation of the vehicle will be described. . First, reservation information is registered in the portable device 1 when getting off or before getting on (state (A)). In the state (A) and the state (B), the vehicle-side unit performs the above-described regular verification during parking.

  When the portable device 1 approaches the vehicle 10 and enters the detection area R1 of the outside-vehicle transmitter 2c (corresponding to the slide door 13) as in the state (B), the portable device 1 sends a request signal for periodic verification. In response to this, a response signal including an ID code and reservation information is transmitted. When the electronic key ECU 4 receives the response signal, the electronic key ECU 4 performs the above-described collation and specifies the position of the portable device 1.

  When ID code verification is established and reservation information is included in the response signal, event verification is performed as in state (C). When the position of the portable device coincides with the position specified in the reservation information, or when the position of the portable device stays at the position set in the reservation information for a predetermined time, the corresponding sliding door 13 Is output to automatically open the door (state (D)).

  When the position of the portable device 1 does not match the position specified in the reservation information, for example, when entering the detection area R2 of the outside-vehicle transmitter 2b and the ID code verification is established, the reservation information is set. An instruction signal may be output so that the sliding door 13 is automatically opened.

  FIG. 4 shows an example of the automatic door opening operation of the sliding door (the same applies to the unlocking operation), and the portable device 1, the vehicle side unit, the door lock control unit, and The flow of the signal between slide door drive parts is shown. In the configuration of the prior art, first, a periodic verification is performed between the portable device 1 and the vehicle side unit (Q101). That is, a request signal is transmitted from the vehicle side unit (outside the vehicle transmitter) (Q102), and the portable device 1 transmits a response signal including the ID code and the reservation information (Q103). When collation is established in the vehicle side unit (Q104), an automatic door opening instruction for the slide door closest to the portable device 1 is output to the corresponding door lock control unit and slide door drive unit (Q105).

  In the configuration of the present invention, first, periodic collation is performed (Q201 to Q203) as in the configuration of the prior art. When collation is established in the vehicle-side unit (Q204), an instruction to automatically open the sliding door specified by the reservation information is output to the corresponding door lock control unit and sliding door driving unit (Q205).

  When the automatic door opening condition includes that the portable device 1 is at the position specified by the reservation information, Q205 is not executed and event matching is performed (Q206). That is, a request signal including the key ID for only the portable device 1 is transmitted from the vehicle exterior transmitter corresponding to the position specified by the reservation information (Q207), and the portable device 1 sends the ID code and the reservation information.
