Description

  The present invention relates to a lock system and a lock device that automatically switch a vehicle door from unlock to lock when getting off by making a reservation in advance.

  In the lock system described in Patent Document 1, a lock reservation operation is performed on a switch provided on a door handle, and after a predetermined time has elapsed since the operation, the lock is performed on condition that all vehicle doors are closed. Until the predetermined time elapses, the vehicle door can be opened and closed, so that the user can take out luggage in the vehicle.

JP 2014-43724 A

  The lock system described in Patent Document 1 locks the switch provided on the door handle when there is a lot of luggage, such as when holding an umbrella or holding a child in the rain. It is difficult to make reservations and is not convenient.

  The present invention has been made in view of such a situation, and an object thereof is to provide a vehicle door locking system and a locking device that are easy to use.

  In order to solve the above-described problems, the lock system is provided in the vehicle, and includes an open / close detection unit that detects opening / closing of the vehicle door, a lock unit that switches between locking and unlocking of the vehicle door, and the intention of the reservation lock is input. A state in which one or more of the vehicle doors are set as reservation lock target doors, and all of the reservation lock target doors are closed from a state where they are opened at least once On-vehicle control that switches the vehicle door from unlocked to locked through the lock section on the condition that the vehicle door is closed, that all the vehicle doors are closed, and that the electronic key is not in the vehicle And a section.

  According to this system, when the intention of the reservation lock is input, the in-vehicle control unit opens and closes all of the reservation lock target doors once or more, and if all of the vehicle doors are closed, Switch from unlock to lock. In other words, when getting off the reservation lock in the vehicle at the time of getting off, if all the reservation lock target doors are opened and closed once or more, the vehicle door is locked. Therefore, there is no need for an operation outside the vehicle such as operating a door handle switch or the like as in the prior art, and there is no need to wait outside the vehicle for a predetermined time. For this reason, it is easy to use even in situations where there are a lot of luggage and it is difficult to use both hands.

  The system includes a display unit that displays a candidate door that is a vehicle door set as the reservation lock target door when the reservation lock intention is input, and the in-vehicle control unit is configured to turn off the engine from on to off. It is preferable that the candidate door is displayed on the display unit by using the switching to be a trigger.

  According to this system, the user can recognize which vehicle door is the candidate door before inputting the intention of the reservation lock. Thereby, it is possible to determine whether or not to perform the reservation lock by inputting the intention of the reservation lock.

  In the system, the display unit displays the reservation lock target door in a display mode different from the display of the candidate door, and the in-vehicle control unit sets the candidate door as the reservation lock target door. It is preferable to switch the display of the candidate door on the display unit to the display of the reservation lock target door using the above as a trigger.

According to this system, the user can recognize that the candidate door is set as the reservation lock target door through visual recognition of the display unit.
In the above system, it is preferable that the in-vehicle control unit sets a vehicle door that is opened and closed between the time when the vehicle door is switched from lock to unlock and when the intention of the reservation lock is input as the candidate door. .

  In many cases where a load is placed in a vehicle or a plurality of people get on, the door that opens and closes before boarding, that is, before traveling, and the door that opens and closes after getting off, that is, after traveling, often coincide. Paying attention to this point, the in-vehicle control unit of this system automatically sets the vehicle doors that are opened and closed during the boarding as candidate doors. That is, it is not necessary for the user himself to set a candidate door. In addition, when a reservation lock intention is input and the candidate door is set as a reservation lock target door, the door is opened and closed when the vehicle gets off. As a result, the reservation lock is performed smoothly, which is convenient.

  In the above system, when the vehicle door set as the candidate door is opened and closed after the vehicle speed falls below a set speed until the reservation lock intention is input. Preferably, the opened / closed vehicle door is excluded from the candidate doors.

  If the vehicle door opens and closes after the vehicle travels between the time when the vehicle speed falls below the set speed and the intention to enter the reservation lock, passengers get off the vehicle door or luggage is removed from the vehicle door Probability is high. In other words, the opened and closed vehicle door is unlikely to be opened and closed in the future. Therefore, when this vehicle door is set as a reservation lock target door, the door is not operated indefinitely, and the reservation lock may not operate. In this respect, according to this system, doors that are unlikely to be opened and closed are excluded from candidate doors. As a result, the door is not displayed on the display unit, and cannot be a reservation lock target door, so that the reservation lock is performed smoothly. Therefore, user convenience is good.

  In the above system, when the vehicle door different from the reservation lock target door is opened and closed after the intention of the reservation lock is input, the in-vehicle control unit limits the reservation lock target door to the door on the driver's seat side. It is preferable.

  For example, it is difficult to open the vehicle door when the parking space of the vehicle is small. At that time, the passenger may move inside the vehicle by a walk-through or the like, and get off from the door on the side opposite to the boarding time. In this case, there is a high possibility that the vehicle door that opens and closes when getting on will not be opened and closed. In this regard, according to this system, when a door different from the reservation lock target door is opened and closed and the reservation lock target door may not be opened and closed, the reservation lock target door is limited to the door on the driver's seat side. Therefore, the user can switch the vehicle door from unlocked to locked by shifting the door on the driver's seat from the opened state to the closed state. For this reason, there is little possibility that the reservation lock condition is not satisfied, that is, the vehicle door is kept in the unlocked state.

  In the system described above, it is preferable that the in-vehicle control unit switches the reservation lock target door to a vehicle door different from that used as a trigger when a switch provided in the vehicle is first specially operated.

According to this system, the reservation lock target door can be switched.
In the system described above, it is preferable that the in-vehicle control unit switches the reservation lock target door to only the door on the driver's seat side, triggered by the first special operation of a switch provided in the vehicle.

According to this system, the reservation lock target door can be only the door on the driver's seat side.
In the above system, it is preferable that the in-vehicle control unit cancels the reservation lock by using a switch provided in the vehicle as a second special operation.

According to this system, the reservation lock can also be released.
In the system described above, the in-vehicle control unit does not depend on a vehicle door that is opened and closed until the vehicle speed becomes equal to or higher than a set speed after the vehicle door is switched from locked to unlocked, and only the driver's seat door is used. It is preferable to set it as a candidate door.

  According to this system, regardless of which vehicle door is opened or closed, only the driver's seat door is automatically set as a candidate door. This eliminates the need for the user to set a candidate door. If the intention of reservation lock is input, when the driver's seat door is set as a reservation lock target door, the door is opened and closed when the user gets off. As a result, the reservation lock is performed smoothly, which is convenient.

  In the above-described system, the detection that the electronic key is not in the vehicle is performed by the fact that the in-vehicle collation with the electronic key is not established, the outside collation with the electronic key is established, and the electronic key It is preferable that any one of the conditions that the outside verification between vehicles is established at least once and the in-vehicle verification between the electronic keys is not established thereafter.

According to this system, since it can be detected that the electronic key is not in the vehicle, it is possible to prevent the electronic key from being confined in the vehicle by the reservation lock.
In the above system, it is preferable that the in-vehicle control unit deletes a display corresponding to the reservation lock target door in the display unit, triggered by the transition from the open state to the closed state of the reservation lock target door. .

According to this system, it is possible to recognize that the reservation lock target door has shifted from an open state to a closed state.
In the above system, the in-vehicle control unit is configured to input a reservation lock intention, set a reservation lock target door, shift the reservation lock target door from an open state to a closed state, and the vehicle door. In addition to satisfying each condition that all of the doors are in a closed state, it is confirmed that a set time has elapsed since the last door of the reservation lock target doors has shifted from the opened state to the closed state. It is preferable to switch the plurality of vehicle doors from unlocked to locked as a trigger.

  According to this system, when a forgotten thing in the vehicle is noticed immediately after closing a vehicle door that is a reservation lock target door, the forgotten thing can be taken out by opening the vehicle door immediately after the closing.

  In the above-described system, a child lock function that allows opening and closing of a vehicle door that is designated in advance from the outside of the vehicle but does not allow opening and closing from the inside of the vehicle is provided, and the in-vehicle control unit receives a reservation lock intention It is preferable to temporarily release the child lock function.

  When the child lock function is functioning, the vehicle door designated in advance cannot be opened or closed from inside the vehicle. Therefore, when the designated vehicle door is a reservation lock target door, a passenger who gets on the door cannot open the door and get off, and the reservation lock does not operate. In this respect, according to this system, there is no situation in which passengers cannot get off from the door on which they got on. Reservation locks can also operate without problems.

  In order to solve the above-mentioned problems, the lock device is provided in the vehicle, an open / close detection unit that detects opening / closing of the vehicle door, a lock unit that switches between locking and unlocking of the vehicle door, and the intention of the reservation lock is input. The reservation unit and the intention of the reservation lock are input, one or more of the vehicle doors are set as reservation lock target doors, and the reservation lock target doors are moved from the opened state to the closed state A vehicle-mounted control unit that switches the vehicle door from unlocked to locked through the lock unit, on condition that all of the vehicle doors are in a closed state and that external verification with the electronic key is established; It is a summary to provide.

  The lock system and the lock device of the present invention are easy to use.

Each component of the electronic key 20 excluding the electronic key control unit 21 is electrically connected to the electronic key control unit 21 and is comprehensively controlled by the electronic key control unit 21.

  The LF receiving unit 22 receives an LF (Low Frequency) band radio signal and converts the received signal into an electric signal. The LF receiving unit 22 includes an RSSI circuit 22a that detects RSSI (signal strength) of the received radio signal.

The UHF transmission unit 23 converts the electrical signal into a UHF (Ultra High Frequency) band radio signal and transmits the radio signal to a predetermined area.
The memory 21 a of the electronic key control unit 21 stores an ID code that is common to the vehicle-mounted control unit 11 of the vehicle 10. The ID code is used for mutual authentication with the in-vehicle control unit 11. When the electronic key 20 receives the request signal requesting transmission of the ID code and RSSI, the response signal including the ID code stored in its own memory 21a and the RSSI detected in the RSSI circuit 22a as a response to the request signal. Generate this and wirelessly transmit it.

<Vehicle>
As shown in FIG. 1, the vehicle 10 includes an on-vehicle controller 11, an LF transmitter 12, a UHF receiver 13, an engine switch 14, an engine controller 15, a door handle sensor 16, and a door lock device 17. A door courtesy 18, a speaker 19, and a reservation switch 30. Each component of the vehicle 10 excluding the in-vehicle control unit 11 is electrically connected to the in-vehicle control unit 11 and is comprehensively controlled by the in-vehicle control unit 11.

The LF transmission unit 12 converts an electrical signal into an LF band radio signal and transmits it to a predetermined area.
The UHF receiver 13 receives a UHF band radio signal and converts the received signal into an electrical signal.

  The engine switch 14 detects a push operation, and the engine control device 15 controls the start and stop of the engine. The door handle sensor 16 detects contact with the door handle, and the door lock device 17 switches between locking and unlocking the door. The door courtesy 18 is a courtesy switch that detects opening and closing of the vehicle door. Here, the door courtesy FR18a that detects the opening and closing of the front right door, the door courtesy FL18b that detects the opening and closing of the front left door, the door courtesy RR18c that detects the opening and closing of the rear right door, and the door courtesy that detects the opening and closing of the rear left door. RL18d is provided. The speaker 19 converts an electric signal into a sound wave and radiates it. The door lock device 17 corresponds to a lock unit, and the door courtesy 18 corresponds to an open / close detection unit.

  The reservation switch 30 detects a pressing operation. As shown in FIG. 2, the reservation switch 30 is provided with LEDs 30a, 30b, 30c, and 30d at positions corresponding to the vehicle doors. Here, the LED 30a is connected to the front right door (hereinafter referred to as FR door), the LED 30b is connected to the front left door (hereinafter referred to as FL door), the LED 30c is connected to the rear right door (hereinafter referred to as RR door), and the rear left door ( Hereinafter, the LEDs 30d correspond to the RL doors). The reservation switch 30 corresponds to the input unit, and the LEDs 30a to 30d correspond to the display unit.

  The memory 11 a of the in-vehicle control unit 11 stores an ID code that is common to the electronic key control unit 21 of the electronic key 20. The ID code is used for mutual authentication with the electronic key control unit 21.

  The in-vehicle control unit 11 periodically generates a request signal for requesting transmission of the ID code and RSSI, and wirelessly transmits the request signal. When receiving the response signal as a response to the request signal, the in-vehicle control unit 11 collates the ID code included in the response signal with the ID code stored in its own memory 11a. When the verification is established, the in-vehicle controller 11 determines whether the electronic key 20 is located inside the vehicle or outside the vehicle from the received RSSI. The reference value for determining the position of the electronic key 20 is stored in the memory 11a.

  The in-vehicle control unit 11 permits the engine to be started when the in-vehicle collation of the electronic key 20 is established. When it is detected that the engine switch 14 is operated in this state, the vehicle-mounted control unit 11 starts the engine through the engine control device 15.

  Moreover, the vehicle-mounted control part 11 permits the switching between lock | rock and unlocking of a door, when collation outside the vehicle of the electronic key 20 is materialized. In this state, when it is detected that the door handle sensor 16 is operated, the vehicle-mounted control unit 11 switches between locking and unlocking the door through the door lock device 17.

  The in-vehicle control unit 11 temporarily stores in the memory 11a, as candidate doors, vehicle doors that are opened and closed during the period from when the door is switched from locked to unlocked until the vehicle speed reaches the set speed (boarding recording period). Here, the candidate door is set as a reservation lock target door when the reservation switch 30 is operated after the engine is stopped. The set speed is a speed set in advance to determine that the vehicle is running, and is stored in the memory 11a.

  When the reservation switch 30 is operated and the following condition is satisfied, the in-vehicle control unit 11 executes a reservation lock for switching the door from unlocked to locked through the door lock device 17. The following conditions indicate that all of the reservation lock target doors have shifted from the opened state to the closed state, that all the vehicle doors are in the closed state, and that outside vehicle verification is established. . In addition, when the reservation switch 30 is double-clicked, the in-vehicle control unit 11 switches the reservation lock target door to only the FR door and executes the reservation lock. Here, double clicking the reservation switch 30 corresponds to a first special operation. Details of the reservation lock will be described with reference to FIGS. In addition, each structure of the vehicle-mounted control part 11, the door lock apparatus 17, the door courtesy 18, and the reservation switch 30 comprises the lock apparatus 40. FIG.

<Reservation lock processing procedure>
Next, the reservation lock processing procedure in the in-vehicle controller 11 will be described with reference to the flowchart of FIG. The reservation lock process is triggered by the fact that the vehicle door has been switched from locked to unlocked.

  As shown in FIG. 4, when the vehicle door is switched from locked to unlocked, the vehicle-mounted control unit 11 uses the vehicle door that is opened and closed until the vehicle speed becomes equal to or higher than the set speed (boarding recording period) as a candidate door. Store (step S1).

  Next, the vehicle-mounted control unit 11 determines whether or not the ignition is switched from on to off (step S2). If YES in step S2, that is, if the ignition is switched from on to off, candidate doors are displayed (step S3). Here, the user is notified of which vehicle door is the candidate door by turning on the LEDs 30a to 30d corresponding to the candidate door.

  Next, the vehicle-mounted control part 11 judges whether the reservation switch 30 was operated (step S4). If YES in step S4, that is, if the reservation switch 30 is operated, the in-vehicle control unit 11 sets the candidate door as a reservation lock target door and displays the reservation lock target door (step S5). Here, by blinking the LEDs 30a to 30d corresponding to the reservation lock target door, the user is notified of which vehicle door is the reservation lock target door and that the reservation lock is confirmed.

  Next, the vehicle-mounted control unit 11 determines whether or not the vehicle door other than the reservation lock target door is not opened or closed (step S6). If YES in step S5, that is, if there is no opening or closing of the vehicle door other than the reservation lock target door, it is determined whether or not all of the reservation lock target doors have shifted from the open state to the closed state (step S5). S7). If YES in step S7, that is, if all of the reservation lock target doors have shifted from the opened state to the closed state, it is determined whether or not the vehicle outside verification has been established (step S8). If YES in step S8, that is, if outside-vehicle verification is established, the vehicle door is switched from unlocking to locking (step S9), and the series of processes is terminated.

If NO in step S2, that is, if the ignition is not switched from on to off, the process of step S2 is repeated.
Further, NO in step S4, that is, the case where the reservation switch 30 is not operated, and NO in step S6, that is, the case where the vehicle door other than the reservation lock target door is opened or closed does not satisfy the reservation lock condition. Therefore, a series of processing is completed without switching the vehicle door from unlocking to locking.

  Furthermore, the vehicle-mounted control unit 11 repeats the process of step S7 if NO in step S7, that is, if all of the reservation lock target doors have not shifted from the opened state to the closed state once.

  Moreover, the vehicle-mounted control part 11 produces | generates the electrical signal for alert | reporting that the taking-out of a key is forgotten, when NO in step S8, ie, a vehicle outside collation is not materialized, and outputs this to the speaker 19 (step S10), step. The process proceeds to S8.

  Next, a reservation lock processing procedure in the vehicle-mounted control unit 11 according to circumstances will be described with reference to time charts shown in FIGS. 5 to 7, Hi and Lo signals represent the operation and detection of each component. Specifically, in door unlocking, Hi indicates that the door locking device 17 switches the door from locking to unlocking, and Lo indicates that the door locking device 17 does not operate. For vehicle speeds greater than or equal to the set speed, Hi indicates that the vehicle speed is greater than or equal to the set speed, and Lo indicates that the vehicle speed is less than the set speed. In IG, Hi indicates that IG (engine) is on (driving), and Lo indicates that IG (engine) is off (stopped). In the boarding recording period, Hi indicates that it is a boarding recording period, and Lo indicates that it is not a boarding recording period. In addition, a boarding recording period is a period which memorize | stores the opened and closed vehicle door as a reservation lock object door. In the disembarkation recording period, Hi indicates that it is a disembarkation recording period, and Lo indicates that it is not a disembarkation recording period. The getting-off recording period is a period for determining whether the opened / closed vehicle door corresponds to the reservation lock target door. In the door courtesy, Hi indicates that the door is open, and Lo indicates that the door is closed. In the LED, Hi indicates that the LED is turned on, and Lo indicates that the LED is turned off. In the reservation SW operation, Hi indicates that the reservation switch 30 has been operated, and Lo indicates that the reservation switch 30 has not been operated. In the LF output (request), Hi indicates that a request signal is generated and wirelessly transmitted, and Lo indicates that a request signal is not generated and wirelessly transmitted. In UHF reception (response), Hi indicates that a response signal has been received, and Lo indicates that no response signal has been received. In the door lock, Hi indicates that the door lock device 17 has switched the door from unlocked to locked, and Lo indicates that the door lock device 17 is not operating.

First, a case where there is no change in the reservation lock target door will be described as a first example. In the first example, it is assumed that a passenger enters through the FR door and the FL door.
(First example)
As shown in FIG. 5, the in-vehicle controller 11 sets the boarding recording period from the time when the vehicle door is unlocked (time T1) until the vehicle speed becomes equal to or higher than the set speed (time T2), and is opened and closed during this period. Record the door as a candidate door. Here, the vehicle-mounted control unit 11 detects that the FR door and the FL door are opened and closed through the door courtesy 18 and stores these two doors as candidate doors.

  Next, the vehicle-mounted control unit 11 temporarily increases the vehicle speed (time T2), becomes equal to or higher than the set speed, and then after the vehicle speed becomes less than the set speed (time T3) until the ignition is turned off (time T4). ), Doors whose vehicle doors have been opened and closed are excluded from candidate doors. Here, it is assumed that all vehicle doors including candidate doors are not opened or closed. When the ignition is turned off (time T4 is reached), the in-vehicle control unit 11 notifies a candidate door that is a target of a reservation lock when the reservation switch 30 is operated. Here, since the FR door and the FL door are candidate doors, the LEDs 30a and 30b are lit as shown in FIG.

  In this state, when the reservation switch 30 is operated (time T5), the in-vehicle control unit 11 sets the candidate door as a reservation lock target door and blinks the LEDs 30a and 30b as shown in FIG. As a result, if the FR door and the FL door, which are reservation lock target doors, shift from the opened state to the closed state, the vehicle door is automatically switched from unlocked to locked, that is, the reservation lock is confirmed. Is notified.

  Next, when detecting that the reservation lock target door has shifted from the open state to the closed state, the in-vehicle control unit 11 turns off the blinking LED. Here, since the FR door and the FL door are opened and closed in this order, the blinking LEDs are also turned off in the order of the LEDs 30a and 30b (time T6). Note that the period from the time T3 to the time T6 that is also the time when the reservation lock target door (here, the FL door) that is to be closed last is the getting-off recording period.

  Thereafter, the vehicle-mounted control unit 11 switches the vehicle door from unlocked to locked after one second from this time T7 (time T8) when all the conditions for the reservation lock are satisfied (time T7). . It should be noted that the vehicle door may be switched from unlocked to locked at the time when the vehicle outside verification is established (time T7). However, since the vehicle door is switched to lock after a predetermined time (1 second in this case) has elapsed from time T7 as in this example, when the vehicle door is closed (time T6), When a forgotten item is noticed, the door can be opened again before the vehicle door switches to lock. Thereby, a forgotten thing can be taken out.

  Next, the case where the candidate door opened and closed during the boarding recording period and the reservation lock target door are different will be described. There are cases where a vehicle door different from the candidate door is automatically set as a reservation lock target door and when it is set manually. The case where the setting is automatically performed in the second example and the case where the setting is performed manually in the third example will be described. Since the times T1 to T8 are the same as those in the first example, detailed description thereof is omitted.

(Second example)
Here, it is assumed that passengers enter from the FR door, the FL door, and the RL door between time T1 and T2, and the FL door is opened and closed between time T3 and time T4.

  As illustrated in FIG. 6, the in-vehicle control unit 11 records doors that are opened and closed from time T1 to time T2 as candidate doors. Here, three doors of the FR door, the FL door, and the RL door are stored as candidate doors.

  Next, when the vehicle door corresponding to the candidate door is opened and closed between time T3 and time T4, the in-vehicle control unit 11 excludes the vehicle door from the candidate door. Here, it is assumed that the FL door is opened and closed. And when the time T4 comes, the vehicle-mounted control part 11 alert | reports the candidate door set as a reservation lock object door, when the reservation switch 30 is operated. Here, since the FR door and the RL door are candidate doors, the LEDs 30a and 30d are lit as shown in FIG. At this point, the user can recognize that the FL door is excluded from the candidate doors. This is because passengers who get on the FL door before the vehicle speed exceeds the set speed are more likely to get off the same FL door before the ignition is turned off, and the FL door may be opened and closed in the future. Is low. In addition, since it is the same as that of the said 1st example after time T5, the detailed description is abbreviate | omitted.

  As described above, the vehicle door that is opened and closed before the ignition is turned off, the vehicle speed is equal to or lower than the set speed, and the reservation switch 30 is operated is automatically excluded from the candidate doors and becomes a reservation lock target door. Since it is not set, user convenience is good.

(Third example)
Here, it is assumed that a passenger enters from the FR door, the RR door, and the RL door from time T1 to T2, and the reservation switch 30 is double-clicked. In addition, before the reservation switch 30 is double-clicked, it is assumed that a passenger who has entered the rear seat from the RR door and the RL door gets off from one door (here, the RL door).

  As illustrated in FIG. 7, the in-vehicle control unit 11 records doors opened and closed from time T1 to time T2 as candidate doors. Here, three doors of the FR door, the RR door, and the RL door are stored as candidate doors.

  Thereafter, when the vehicle-mounted control unit 11 reaches time T4, the LEDs 30a, 30c, and 30d corresponding to the candidate doors are turned on. When the user double-clicks the reservation switch 30 after the RL door is opened and closed, the RL door is excluded from the candidate doors, and the LED 30d corresponding to the RL door is turned off (time T5), the in-vehicle control unit 11 The reservation lock target door is the FR door only, and as shown in FIG. 3C, the LED blinks only the LED 30a. At this point, the user can recognize that the RR door is excluded from the reservation lock target door. In addition, since it is the same as that of the said 1st example after time T5, the detailed description is abbreviate | omitted.

  In many cases, the rear seat of the vehicle is a walk-through, and it is often the case that the vehicle gets off from a door opposite to the driver's seat side, which is safer than the roadway. In this situation, there is a high possibility that not all of the reservation lock target doors recorded at the time of boarding will be opened and closed, but by double-clicking the reservation switch 30 as in this example, the reservation lock target doors are only FR doors. Therefore, it is convenient for the user.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) The vehicle-mounted control unit 11 sets a vehicle recording period from when the vehicle door is switched from locked to unlocked until the vehicle speed becomes equal to or higher than the set speed, and the vehicle door opened and closed during this boarding recording period is a candidate door. Remember as. And the vehicle-mounted control part 11 sets a candidate door to a reservation lock object door by having operated the reservation switch 30 as a trigger. And the vehicle-mounted control part 11 transfers to the closed state from the state in which all the reservation lock object doors were opened one or more times, and is in the state in which all the vehicle doors were closed, and also external communication between the electronic keys 20 is carried out. When established, the vehicle door is switched from unlocked to locked. As a result, the user can switch the vehicle door from unlocked to locked only by closing the vehicle door outside the vehicle without requiring any other operation, which is convenient even in a situation where both hands are occupied. .

  (2) When the candidate door is opened and closed after the boarding recording period and before the reservation switch 30 is operated after the boarding recording period ends, the in-vehicle control unit 11 The door was excluded from the candidate doors. From when the candidate door is set to when the reservation switch is operated, that is, when the vehicle door is opened and closed after the vehicle travels, passengers other than the user have already got off the vehicle door or the luggage has been taken out from the vehicle door It is highly possible. In other words, the opened and closed vehicle door is unlikely to be opened and closed in the future. Therefore, when this vehicle door is not excluded from the candidate doors and becomes a reservation lock target door, the door is not operated any time, and the vehicle-mounted control unit switches the vehicle door including the door from unlock to lock. You may not be able to. In that respect, the in-vehicle control unit 11 of this system excludes doors that are unlikely to be opened and closed from the candidate doors, so that the reservation lock is performed smoothly. Therefore, user convenience is good.

  (3) The reservation switch 30 is provided with LEDs 30a to 30d. And the vehicle-mounted control part 11 was made to light LED30a-30d applicable to a candidate door. Thereby, the user can recognize which door is the candidate door.

  (4) The in-vehicle control unit 11 blinks the LEDs 30a to 30d corresponding to the reservation lock target doors that are lit, triggered by the operation of the reservation switch 30. As a result, the user can recognize that the reservation lock has been confirmed.

  (5) The in-vehicle control unit 11 releases the reservation lock when the vehicle door different from the reservation lock target door is opened and closed after the reservation switch 30 is operated. Further, the blinking LEDs 30a to 30d are turned off. For example, the left door may be difficult to open because of the door opening / closing space. In such a situation, a person who gets on from the left door often gets out of the right door. In this case, since the left door, that is, the reservation lock target door, will not be opened and closed in the future, there is a high possibility that the reservation lock condition will not be satisfied. On that point, when there is a high possibility that the reservation lock condition is not satisfied, the in-vehicle control unit 11 releases the reservation lock and notifies the fact by turning off the LEDs 30a to 30d. Thereby, the user can recognize that the reservation cannot be locked. As a result, the user can switch the vehicle door from unlocked to locked using the electronic key 20 himself. That is, there is little possibility that the vehicle door is maintained in the unlocked state.

  (6) The in-vehicle control unit 11 switches the reservation lock target door only to the door on the driver's seat (FR door) using the double click of the reservation switch 30 as a trigger. As a result, if only the door on the driver's seat side is closed, the reservation is locked, which is convenient for the user.

  (7) The vehicle-mounted control unit 11 turns off the blinking LEDs 30a to 30d, triggered by the transition from the open state to the closed state of the reservation lock target door. Thereby, the user can recognize that the reservation lock target door has shifted from the opened state to the closed state.

  (8) The in-vehicle controller 11 is a reservation lock target door by switching the vehicle door to the lock after a predetermined time (here, 1 second) has elapsed after all the reservation lock conditions are satisfied. When a forgotten item in the vehicle is noticed immediately after closing the vehicle door, the forgotten item can be taken out by opening the vehicle door immediately after the closing.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIG. In the first embodiment, NO in step S6 of FIG. 4, that is, if there is an opening / closing in a vehicle door other than the reservation lock target door, the reservation door is not satisfied and the vehicle door is changed from unlocked to locked. A series of processing is completed without switching, but this processing is omitted in the second embodiment, which is a difference between the two embodiments. For this reason, the detailed description is abbreviate | omitted about the part similar to embodiment of the said 1st Embodiment.

  Here, it is assumed that a passenger enters from the FR door, the FL door, and the RR door from time T1 to T2, and the reservation switch 30 is double-clicked. Further, a case will be described in which a passenger who has entered the rear seat from the RR door gets off the door (here, the RL door) opposite to the boarding side.

  As shown in FIG. 8, the vehicle-mounted control unit 11 records doors that are opened and closed from time T1 to time T2 as candidate doors. Here, three doors of the FR door, the FL door, and the RR door are stored as candidate doors.

  Thereafter, the vehicle-mounted control unit 11 turns on the LEDs 30a, 30b, and 30c when time T4 is reached. When the user double-clicks the reservation switch 30 (time T5), the in-vehicle control unit 11 sets the reservation lock target door only to the FR door, and also blinks the LED only to the LED 30a. At this time, the user can recognize that the FL door and the RR door are excluded from the reservation lock target doors. After that, even if the FL door and the RR door that are not the reservation lock target doors are opened and closed, the opening and closing of these two doors is not included in the conditions for releasing the reservation lock, so the reservation lock is continued. When the FR door that is the reservation lock target door is opened and closed (time T6), the vehicle door is switched from unlocked to locked after time T7 to T8.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(9) The condition for canceling the reservation lock, that is, the condition for continuing the reservation lock, does not include that doors other than the reservation lock target door are not opened and closed. Thus, as in the third example of the first embodiment, the reservation lock is continued even when the passenger gets off from the door on the side opposite to the driver's seat where the passenger has boarded. In addition, it is preferable for the convenience of the user to have a function of switching the reservation lock target door only to the FR door by double-clicking the reservation switch 30.

(Third embodiment)
Next, a third embodiment will be described with reference to FIG. In the third embodiment, a description will be given of a case where a reservation lock is introduced into a vehicle equipped with a so-called child lock function that allows the opening operation of the vehicle door from the outside of the vehicle and does not allow the opening operation from the inside of the vehicle. Note that the difference between the present embodiment and the first embodiment is that the processing between step S4 and step S6 in the in-vehicle controller 11 and the processing after step S9 are different. That is, since each process of step S1-S4, step S6-S9, and step S10 is the same as each process shown in FIG. 4, the detailed description is abbreviate | omitted.

  As shown in FIG. 9, when YES in step S4, that is, when the reservation switch 30 is operated, the in-vehicle controller 11 sets the candidate door as a reservation lock target door and displays the reservation lock target door (step). S5). Further, the child lock function is released (step S11). As a result, the candidate door can be opened and closed from inside the vehicle. And the vehicle-mounted control part 11 performs the process of step S6 transfer.

  Then, after performing the process of steps S6 to S8 (including the process of step S10 in some cases), the vehicle-mounted control unit 11 switches the vehicle door from unlocked to locked (step S9), and the child lock function is activated. The resetting is performed (step S12), and the series of processes is terminated.

  Note that if NO in step S4, that is, if the reservation switch 30 is not operated, the reservation lock condition is not satisfied, and thus the series of processing ends without switching the vehicle door from unlocking to locking.

  Also, if NO in step S6, that is, if the vehicle door other than the reservation lock target door is opened or closed, the reservation lock condition is not satisfied, but the child lock function has been released at this point, so the process goes to step S12. The process is shifted to end the series of processes without switching the vehicle door from unlocking to locking.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(10) The child lock function is canceled with the operation of the reservation switch 30 as a trigger. Thereby, the passenger can open the vehicle door opened and closed at the time of boarding from the inside of the vehicle, and get off from the door. The reservation lock can also be operated without any problem.

In addition, you may change each said embodiment as follows.
In the second embodiment, the vehicle-mounted control unit 11 may limit the reservation lock target door to the driver side door when a vehicle door different from the reservation lock target door is opened and closed. In this way, when the door different from the reservation lock target door is opened and closed and the reservation lock target door may not be opened and closed, by limiting the reservation lock target door to the driver side door, the user can If the door is shifted from the opened state to the closed state, the vehicle door can be switched from unlocked to locked. For this reason, there is little possibility that the reservation lock condition is not satisfied, that is, the vehicle door is kept in the unlocked state.

In the third embodiment, the processing order of step S5 and step S11 may be reversed.
The third embodiment may be applied to the second embodiment. That is, the in-vehicle control unit 11 may not perform the process of step S6.

  In each of the above embodiments, when the reservation switch 30 is double-clicked as the first special operation, the reservation lock target door is changed to only the FR door, but may be changed to another door. In addition, the other door here is not limited to one door, and may be a combination of two to four doors. Further, the reservation lock may be released when the reservation switch 30 is operated in a second special operation different from the first special operation, such as a long press. For example, the reservation lock may be released when the reservation switch 30 is pressed for a long time after the reservation switch 30 is once operated and the reservation lock is confirmed. Once released, it is possible to open / close a door different from that and set the door different from that before the second special operation of the reservation switch 30 as a reservation lock target door.

  In each of the above-described embodiments and other examples, the function of switching the reservation lock target door by the first special operation of the reservation switch 30 is provided, but this function is not necessarily a function that needs to be installed. Further, only the reservation lock releasing function by the second special operation of the reservation switch 30 shown in the above-described another example may be installed.
