Description

  The present invention relates to an automatic lock system that locks all of a plurality of vehicle doors after a certain period of time has passed without unlocking the vehicle doors after unlocking the vehicle doors.

  Conventionally, for example, a so-called wireless remote control system described in Patent Document 1 is known. In the technique described in this document, when an unlock switch provided on an electronic key (portable device) is operated (first unlock operation), an ID code signal is transmitted from the electronic key to the vehicle by wireless one-way communication. The vehicle door is unlocked (unlocked). When any of the plurality of vehicle doors is left open for a certain period of time without being opened, all the vehicle doors are automatically locked (locked) (timed automatic lock function). This prevents the vehicle from being left with the vehicle door unlocked, thereby preventing the vehicle from being stolen.

Such a timed automatic lock function is also applied to a so-called smart entry system that performs wireless two-way communication between an electronic key and a vehicle. That is, based on the fact that the user performs a second unlocking operation of touching the touch sensor provided on the door outside handle, and that the vehicle exterior verification is established by wireless two-way communication between the electronic key and the vehicle. Even when the doors are unlocked, all the vehicle doors are automatically locked if they are left for a certain period of time without being opened.
JP-A-62-253884

  By the way, in the wireless remote control system, the portable device may be confined in the vehicle interior due to the timekeeping auto-lock function.

  Specifically, for example, it is assumed that there are two users of a vehicle carrying the portable device. Then, it is assumed that one user leaves the vehicle while keeping his / her portable device in the passenger compartment, and the other user leaves the vehicle as it is after the unlocking operation with his / her portable device. Then, since the vehicle door is not opened after the unlocking operation by the latter user, all the vehicle doors are locked after a lapse of a certain time, and the former user's portable device is confined in the vehicle interior.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an auto-lock system that can further reduce the lock-in of the portable device into the vehicle interior without reducing the security. There is.

  In order to achieve such an object, according to the first aspect of the present invention, an unlock switch is provided, and when the unlock switch is pressed, a predetermined vehicle door among a plurality of vehicle doors of the vehicle is provided. When a portable device that wirelessly transmits an unlocking signal for instructing unlocking to the vehicle, door open / closed state detecting means for individually detecting the open / closed states of the plurality of vehicle doors, and the unlocking signal received An unlock operation determination unit that determines that a first unlock operation for unlocking a predetermined vehicle door among the plurality of vehicle doors has been performed, and a first unlock operation performed by the unlock operation determination unit. An elapsed time measuring unit that measures an elapsed time starting from the last determined time point, and a first unlocking operation based on the first unlocking operation being determined by the unlocking operation determining unit. An unlock execution unit that unlocks a predetermined vehicle door corresponding to the unlock operation, and after the vehicle door is unlocked by the unlock execution unit, any of the plurality of vehicle doors is detected by the door open / close state detection means. When it is determined that the elapsed time measured by the elapsed time measurement unit exceeds a predetermined time without being detected to be opened, a timed auto-lock that locks all of the plurality of vehicle doors is executed. An auto-lock system including an auto-lock executing unit that stores and holds the locked state of the plurality of vehicle doors when the unlock operation determining unit determines that the first unlock operation has been performed. And the auto-lock executing unit is in a locked state of the plurality of vehicle doors stored and held in the storage holding unit. Therefore, when it is determined that the plurality of vehicle doors are all locked when the first unlocking operation is performed, the time counting auto-lock is performed, while the plurality of vehicles are operated when the first unlocking operation is performed. When it is determined that any of the doors has been unlocked, the timed auto-lock is not executed.

  If one of the doors is already unlocked, even if it is necessary to get into the vehicle or take the luggage in the passenger compartment, it is only necessary to open the already unlocked door. Less need to operate. Therefore, when it is determined that the first unlocking operation has been performed in a state where any one of the doors is already unlocked, there is a high possibility of erroneous determination or erroneous operation. In addition, since one of the doors is unlocked, there is a possibility that the door is opened and the portable device is temporarily placed in the vehicle interior. Therefore, in the above configuration as an auto-lock system, when any of the vehicle doors is unlocked when the first unlocking operation is performed, the timed auto-lock is not executed. Therefore, it is possible to reduce confinement of the portable device in the vehicle interior.

  On the other hand, when the first unlocking operation is performed in a normal case where the first unlocking operation is performed, that is, in a state where all the plurality of vehicle doors are locked, the timed auto-locking is executed as usual. Accordingly, it is possible to prevent a decrease in security.

  Further, in the auto-lock system according to claim 1, in the invention according to claim 2, wireless two-way communication is performed between the portable device and the vehicle, and a predetermined range outside the vehicle is set in advance. A vehicle exterior verification means for performing a vehicle exterior verification to determine whether or not there is a registered portable device, and a contact signal provided outside the vehicle compartment of the vehicle door to detect that it has been touched by the user and to indicate that And a touch sensor that transmits a second unlocking operation for unlocking a predetermined vehicle door among the plurality of vehicle doors when the contact signal is received. The elapsed time measuring unit starts from the time point when the unlock operation determining unit finally determines that either the first unlock operation or the second unlock operation has been performed. The time is measured, and the unlock execution unit determines that the first unlock operation has been performed by the unlock operation determination unit and that the second unlock operation has been performed by the unlock operation determination unit. And on the basis of any one of the determined that there is a pre-registered portable device in a predetermined range outside the vehicle by the vehicle exterior verification means, the corresponding predetermined vehicle door is unlocked, The memory holding unit stores and holds the locked state of the plurality of vehicle doors when the unlock operation determining unit determines that one of the first unlock operation and the second unlock operation is performed, The auto-lock execution unit is configured to perform the first unlocking operation and the second unlocking operation based on the locked state of the plurality of vehicle doors stored and held in the storage holding unit. When it is determined that all of the plurality of vehicle doors are locked when any one of the operations is performed, the timed auto-lock is executed, while either the first unlocking operation or the second unlocking operation is performed. When it is determined that any one of the plurality of vehicle doors is unlocked, the timed auto-lock is not executed.

  Similarly to the structure of claim 1, if any door is already unlocked, even if it is necessary to get into the vehicle or take the luggage in the passenger compartment, the door is already unlocked. Therefore, it is not necessary to separately perform the first unlocking operation or the second unlocking operation. Therefore, when it is determined that the first unlocking operation or the second unlocking operation has been performed in a state where any one of the doors is already unlocked, there is a high possibility of erroneous determination or erroneous operation. In addition, since one of the doors is unlocked, there is a possibility that the door is opened and the portable device is temporarily placed in the vehicle interior. Therefore, in the above configuration as an auto-lock system, when any of the vehicle doors is unlocked when the first unlocking operation or the second unlocking operation is performed, the timed auto-lock is not executed. . Therefore, it is possible to reduce confinement of the portable device in the vehicle interior.

  On the other hand, a normal case where the first unlocking operation or the second unlocking operation is performed, that is, when the first unlocking operation or the second unlocking operation is performed in a state where a plurality of vehicle doors are all locked, As before, clock auto-lock is performed. Accordingly, it is possible to prevent a decrease in security.

  In the auto-lock system according to claim 2, the invention according to claim 3 further includes vehicle interior verification means for determining whether or not the portable device is present in the vehicle interior of the vehicle, wherein the auto-lock execution is performed. When it is determined that any of the plurality of vehicle doors is unlocked when the second unlocking operation is performed, the unit determines whether the portable device is in the vehicle interior by the vehicle interior verification means. When the portable device is determined to be in the vehicle interior, the timekeeping auto-lock is not performed. On the other hand, when the portable device is determined not to be in the vehicle interior, the timekeeping auto-lock is performed. It is characterized by that.

  When it is determined that one of the vehicle doors is unlocked when the second unlocking operation is performed, the portable device may be in the vehicle interior. Therefore, it is determined by the vehicle interior verification means whether the portable device is in the vehicle interior. When it is determined that the portable device is in the vehicle interior, the timed auto-lock is not executed. On the other hand, when the portable device is determined not to be in the vehicle interior, the timed auto-lock is executed. It is possible to further prevent the deterioration of security while reducing the confinement in the room.

  Moreover, in the configuration according to any one of claims 1 to 3, in the invention according to claim 4, the auto-lock execution unit is configured to unlock the unlock execution unit based on the unlocking signal. When performed, the timed auto-lock is executed regardless of the locked state of the plurality of vehicle doors.

  When the unlocking signal is transmitted by pressing the unlock switch of the portable device and unlocking is performed, it can be said that the portable device is possessed by the user of the vehicle. Therefore, in such a configuration as an auto-lock system, when the unlock execution unit unlocks based on the unlocking signal, timed auto-lock is executed regardless of the state of the vehicle door. Thereby, the fall of security can be prevented further, reducing the closure of a portable machine in the vehicle interior.

  Hereinafter, an embodiment of an auto-lock system according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing the overall configuration of the auto-lock system 1 of the present embodiment. The auto-lock system 1 according to the present embodiment is embodied as a so-called smart entry system that uses wireless bidirectional communication between the electronic key 200 and the vehicle-side device 100.

  As shown in FIG. 1, the auto-lock system 1 according to the present embodiment includes a vehicle-side device 100 and an electronic key (portable machine) 200 that are mounted on a vehicle (not shown). First, the configuration and function of the vehicle side device 100 will be described.

  The vehicle-side device 100 has a vehicle interior transmitter 102 and a vehicle interior transmitter 104. The vehicle interior transmitter 102 is provided, for example, between a front seat and a rear seat in the vehicle interior, and forms a detection area for detecting the electronic key 200 so as to include the vehicle interior.

  For convenience of illustration, the outside-vehicle transmitter 104 is illustrated as a single transmitter in FIG. 1, but is configured with, for example, “3 [pieces]” outside-vehicle transmitters. That is, the out-of-vehicle transmitter 104 is provided between a right front door (hereinafter also referred to as a D seat door) and a right rear door (hereinafter also referred to as a DR seat door), and the right side of the D seat door and the DR seat door. Between the left front door (hereinafter also referred to as the P seat door) and the left rear door (hereinafter also referred to as the PR seat door). The transmitter outside the passenger compartment that forms the detection area on the left side of the P seat door and the PR seat door (the vehicle outside in the vehicle width direction), and the luggage door or the vicinity thereof, the detection area is formed behind the luggage door It consists of a transmitter outside the vehicle. By the way, these detection areas are set to have a radius of about “0.7 to 1.0 m” centered on each outside-vehicle transmitter, for example.

  In addition, as shown in FIG. 1, the vehicle-side device 100 has an ECU 108. The ECU 108 is a computer that includes a CPU 110, a memory 112, and the like, and executes various processes in accordance with programs stored in advance in the memory 112 and the like.

  For example, the CPU 110 performs the following processing according to a program stored and held in advance in the memory 112 or the like. That is, the CPU 110 transmits the vehicle outside transmitter 104 at predetermined intervals set in a short time of “about 0.3 [second]” when the vehicle is parked and the vehicle door is locked (locked). Output a transmission request signal. When the transmission request signal is supplied, the out-of-vehicle transmitter 104 transmits the transmission request signal to the detection area. When the electronic key 200 is in the detection area when the transmission request signal is transmitted by the outside transmitter 104, a response signal including an ID code is returned from the electronic key 200 (wireless two-way communication).

  As shown in FIG. 1, the vehicle-side device 100 has a receiver 106. The receiver 106 is installed at a predetermined position inside the vehicle, and receives the response signal returned from the electronic key 200 as described above. The receiver 106 also receives an unlocking signal, a locking signal, etc., which will be described later, transmitted from the electronic key 200 (wireless one-way communication). Then, the receiver 106 outputs received signals such as the response signal, the unlocking signal, and the locking signal to the ECU 108.

  The ECU 108 (specifically, the CPU 110) outputs a transmission request signal to the vehicle interior transmitter 102 and the vehicle interior transmitter 104 in order at different times. Therefore, the CPU 110 can determine from which detection area the response signal is transmitted by determining when the response signal is supplied. That is, the CPU 110 can determine in which detection area the electronic key 200 is present, and therefore can determine whether the electronic key 200 is located inside or outside the vehicle interior.

  As described above, the response signal supplied to the CPU 110 includes the ID code of the electronic key 200 that returned the response signal. Therefore, the CPU 110 can collate the electronic key 200 that has returned the response signal. As described above, since the location of the electronic key 200 can also be determined, the CPU 110 can execute the exterior comparison and the interior verification of the electronic key 200.

  In addition, as shown in FIG. 1, the vehicle-side device 100 has a touch sensor 114. The touch sensor 114 is provided on each door outside handle (not shown) of a vehicle door (D seat door, P seat door, DR seat door, PR seat door, etc.) for the user to get on and off the seat. Then, it is detected that the vehicle passenger has touched the steering wheel, and a contact signal indicating that is supplied to the ECU 108.

  As shown in FIG. 1, the ECU 108 is connected to a door lock mechanism 116. The ECU 108 can also send and receive signals to and from the door lock mechanism 116. Here, the door lock mechanism 116 can lock (lock) the vehicle door based on a signal from the ECU 108 or unlock (unlock) the vehicle door. Whether it is closed (that is, the actual opening / closing state of the vehicle door) can be detected separately. The door lock mechanism 116 corresponds to the door open / closed state detecting means described in the claims.

  Next, the configuration of the electronic key 200 will be described. As shown in FIG. 1, the electronic key 200 includes a receiving unit 202, a transmitting unit 204, an ECU 206, an unlock switch 208, and a lock switch 210.

Among these, the receiving part 202 receives the transmission request signal transmitted from the vehicle interior transmitter 102 and the vehicle interior transmitter 104, and outputs the received transmission request signal to the ECU 206. The unlock switch 208 is a switch that is operated when the user instructs transmission of an unlocking signal.
The lock switch 210 is a switch operated when a user instructs transmission of a locking signal. When the unlock switch 208 and the lock switch 210 are operated by the user, the ECU 206 outputs a signal indicating that the unlock switch 208 and the lock switch 210 are operated.

  When the transmission request signal is supplied from the receiving unit 202, the ECU 206 generates a response signal including the ID code of the electronic key 200 and outputs the response signal to the transmitting unit 204 (wireless bidirectional communication, so-called smart). When a signal is input from the lock switch 208, an unlocking signal indicating that the unlocking operation has been performed is output to the transmission unit 204 (wireless one-way communication, so-called wireless), and the signal is input from the lock switch 210. Then, a locking signal indicating that the locking operation has been performed is output to the transmission unit 204 (wireless one-way communication, so-called wireless). Then, the transmission unit 204 transmits various signals supplied from the ECU 206.

  Based on the above description, the ECU 108 will be further described. The ECU 108 (specifically, the CPU 110) determines whether or not to receive from the touch sensor 114 a contact signal indicating that the vehicle passenger has touched the door outside handle in the detection area where the electronic key 200 is detected. Note that the ECU 108 determines that the second unlocking operation has been performed when the contact signal is received. Therefore, the ECU 108 corresponds to the unlock operation determination unit described in the claims. The ECU 108 also determines whether or not the vehicle interior verification is established by the wireless two-way communication with the electronic key 200. Here, when the contact signal is received from the touch sensor 114 and the outside verification of the electronic key 200 is established, the ECU 108 unlocks a predetermined vehicle door among the plurality of vehicle doors by the door lock mechanism 116 ( Unlock).

  In addition, when the signal received by the receiver 106 is the unlocking signal, the ECU 108 (specifically, the CPU 110) determines that the first unlocking operation has been performed, and sets a predetermined vehicle door among the plurality of vehicle doors to the door. Unlock (unlock) by the lock mechanism 116. When the signal received by the receiver 106 is the locking signal, the ECU 108 locks (locks) a predetermined vehicle door of the plurality of vehicle doors by the door lock mechanism 116.

  Further, ECU 108 (specifically, CPU 110) stores and holds the locked state of the vehicle door at that time in memory 112 when the vehicle exterior verification is established and unlocked. The memory 112 corresponds to a storage holding unit described in the claims. In the present embodiment, the memory 112 is used as the storage holding unit, but the present invention is not limited to this. In addition, a hard disk drive device or the like can be employed. Further, when the unlocking is performed, the ECU 108 measures an elapsed time starting from the unlocking.

  Then, when it is determined that the elapsed time exceeds a predetermined time (for example, “30 [seconds]”) without detecting that any of the vehicle doors is opened by the door lock mechanism 116, the memory When it is determined that all the vehicle doors are locked when the first unlocking operation or the second unlocking operation is performed based on the locked state of the vehicle door stored in 112, the door lock mechanism 116 is used. To lock all vehicle doors.

  On the other hand, the CPU 110 detects that the elapsed time exceeds a predetermined time (for example, “30 [seconds]”) without detecting that any of the vehicle doors has been opened by the door lock mechanism 116. However, based on the locked state of the vehicle door stored in the memory 112, it is determined that one of the vehicle doors has been unlocked when the unlocking operation (second unlocking operation) by wireless two-way communication is performed. If so, the following determination is further made.

  That is, the electronic key 200 further performs vehicle interior verification to determine whether or not the electronic key 200 is in the vehicle interior. When it is determined that the electronic key 200 is not in the vehicle interior, all the vehicle doors are locked by controlling the door lock mechanism 116. However, CPU 110 does not unlock when it is determined that electronic key 200 is in the passenger compartment.

  By the way, a conventional auto-lock system, that is, a wireless entry system that automatically locks all doors when a predetermined time has passed without any of the vehicle doors being opened after the first unlocking operation. Then, the electronic key may be trapped in the passenger compartment.

  Specifically, for example, it is assumed that there are two users of a vehicle carrying the electronic key 200 each. Then, it is assumed that one user leaves the vehicle while keeping his / her own electronic key 200 in the passenger compartment, and the other user leaves the vehicle as it is after performing an unlocking operation using his / her own electronic key 200. Then, since the vehicle door is not opened after the unlocking operation by the latter user, all the vehicle doors are locked after a lapse of a certain time, and the electronic key 200 of the former user is confined in the vehicle interior.

  Hereinafter, the operation of the auto-lock system 1 that solves these problems will be described with reference to FIG. FIG. 2 is a flowchart showing a processing procedure of auto-lock processing executed by the auto-lock system 1.

  When this auto-lock process is started, the ECU 108 first determines whether or not either the first unlocking operation of the vehicle door or the second unlocking operation of the vehicle door has been performed as the determination process of step S1. To do. That is, it is determined whether a contact signal is received from the touch sensor 114 and whether an unlocking signal is received from the electronic key 200. If it is determined that neither the first unlocking operation nor the second unlocking operation is performed (“No” in the determination process of step S1), the ECU 108 executes the determination process of step S1 again. To do. In short, the ECU 108 is on standby until either the first unlocking operation or the second unlocking operation is executed, and when it is determined that either unlocking operation has been performed (in the determination process of step S1). “Yes”), the ECU 108 unlocks a predetermined door determined based on the unlocking operation, and then executes the determination process in the subsequent step S2.

  The ECU 108 determines whether or not any of the vehicle doors has been opened based on the actual open / closed state of the vehicle door detected by the door lock mechanism 116 as the determination process in the subsequent step S2. Here, when it is determined that any of the vehicle doors has been opened (“Yes” in the determination process in step S2), the ECU 108 ends the auto-lock process as it is.

  On the other hand, if it is determined that none of the vehicle doors are opened in the determination process of step S2 (“No” in the determination process of step S2), the vehicle is left in an unlocked state, Over a long period of time, the possibility of the vehicle being stolen increases. Therefore, the ECU 108 measures the elapsed time starting from the time when the first unlocking operation or the second unlocking operation was last executed as the determination process in the subsequent step S3, and the elapsed time is a fixed time (for example, “ 30 [seconds] ”) is determined. Here, when it is determined that the elapsed time has not reached the predetermined time (“No” in the determination process of step S3), the time during which the vehicle door is unlocked and the vehicle is left is short. Therefore, the ECU 108 determines whether it takes a long time for the vehicle door to remain unlocked while the vehicle door is unlocked by repeatedly executing the determination process of step S2 and the determination process of step S3. .

  Here, when it is determined that the elapsed time exceeds a certain time (“Yes” in the determination process of step S3), the vehicle is left unattended and the vehicle is left unattended for a long time. All the vehicle doors should be locked in order to increase the possibility of theft and prevent such vehicle theft. However, it is necessary to prevent the electronic key 200 from being closed in the passenger compartment. Therefore, the ECU 108 determines whether the unlocking operation has been performed by a second unlocking operation in which the unlocking operation has been touched on the touch sensor 114 or a first unlocking operation in which the unlocking switch 208 of the electronic key 200 has been pressed. Determine if it is an operation. The former case is an unlock operation in a so-called smart system, and the latter case is an unlock operation in a wireless system.

  In the case of the unlocking operation in the wireless system, the electronic key 200 is possessed by the user, so that the electronic key 200 is not confined in the vehicle compartment when all the vehicle doors are locked. Therefore, the ECU 108 locks all the vehicle doors as the process of the subsequent step S5, and ends this auto-lock process.

  On the other hand, when it is determined in the determination process of the previous step S4 that the unlocking operation is performed in the smart system, as in the case described above, the vehicle exterior verification is established even though the electronic key 200 is in the vehicle interior. There is a possibility that it was unlocked. In this case, if all the vehicle doors are locked, the electronic key 200 is confined in the vehicle interior. Therefore, the ECU 108 determines whether or not all the vehicle doors are locked at the time of the unlocking operation, as a determination process in the subsequent step S6.

  Here, when it is determined that all the vehicle doors are locked (“Yes” in the determination process of step S6), it is considered that the possibility of the electronic key 200 being in the vehicle interior is low because it is a normal case. . Therefore, the ECU 108 locks all the vehicle doors with priority given to security as the processing of the subsequent step S5.

  On the other hand, if it is not determined that all the vehicle doors are in the locked state in the determination processing in the previous step S6 ("No" in the determination processing in step S6), it means that one of the vehicle doors is in the unlocked state. . In this case, since there is a possibility that the electronic key 200 is in the vehicle interior as in the above case, the ECU 108 executes the vehicle interior verification of the electronic key 200 as the processing of the subsequent step S7, and the determination processing of the subsequent step S8. As described above, it is determined whether or not the vehicle interior verification of the electronic key 200 is established.

  Here, when it is not determined that the vehicle interior verification of the electronic key 200 is established (“No” in the determination process of step S8), it means that the electronic key 200 is outside the vehicle interior. Therefore, ECU108 locks all the vehicle doors as the process of following step S5. Even when auto-locking is performed in this manner, it is confirmed that the electronic key 200 is outside the vehicle compartment, and therefore there is no possibility that the electronic key 200 is trapped inside the vehicle compartment. On the other hand, when it is determined that the vehicle interior collation of the electronic key 200 is established (“Yes” in the determination process of step S8), the electronic key 200 means that the vehicle is in the vehicle interior. finish. Thereby, it can reduce reliably that the electronic key 200 is confined in a vehicle interior.

  The auto-lock system according to the present invention is not limited to the configuration exemplified in the above embodiment, and can be implemented with various modifications without departing from the spirit of the present invention. . In other words, for example, the following embodiment can be implemented by appropriately changing the above embodiment.

  In the above embodiment, as shown in FIG. 2, the ECU 108 determines whether the unlock operation is the smart second unlock operation or the wireless first unlock operation as the determination process in step S4. However, this determination process may be omitted. That is, as in the modification shown in FIG. 3 as a diagram corresponding to FIG. 2, the ECU 108 determines that the elapsed time exceeds the predetermined time in the determination process of step S3. You may transfer to processing.

  Further, in the above embodiment, as shown in FIG. 2 or FIG. 3, the ECU 108 performs the vehicle interior verification of the electronic key 200 as the process of step S7, and the electronic key as the determination process of the subsequent step S8. Although it has been determined whether or not 200 vehicle interior matching is established, the processing in step S7 and the determination processing in step S8 may be omitted.

  Specifically, as in the modification shown in FIG. 4, the process of step S7 and the determination process of step S8 are omitted from the auto-lock process shown in FIG. 2, and in the determination process of step S6, the vehicle door is If it is determined that all are not locked, the auto-lock process may be terminated as it is. Specifically, the ECU 108 proceeds to the determination process in step S6 when it is determined in the determination process in step S3 that the elapsed time exceeds a certain time. If it is determined in step S6 that all the vehicle doors are locked, the ECU 108 locks all the vehicle doors in step S5, and ends the auto-lock processing. On the other hand, if it is not determined in the determination process of step S6 that all the vehicle doors are locked, if the ECU 108 terminates this auto-lock process without locking all the vehicle doors, the security is reduced. Therefore, it is possible to further reduce the closing of the portable device into the vehicle interior.

  In the above embodiment, both the wireless system and the smart system are provided. However, the smart system may be omitted and only the wireless system may be provided. That is, as shown in FIG. 5 as a diagram corresponding to FIG. 1, the auto-lock system 1a includes the electronic key 200a from which the receiving unit 202 is omitted, the vehicle interior transmitter 102, and the vehicle exterior transmitter 104. It is good also as comprising the vehicle side apparatus 100a.
