JP 2002-129794 A

  In a system that locks / unlocks a vehicle door using communication between a portable device carried by a user and an in-vehicle device, such as a keyless entry system as described above or a so-called smart entry system, the user is usually used. The operation for instructing the lock by is accepted only when all the vehicle doors are closed. In other words, even if the lock instruction operation is performed by the user in a state where any one of the vehicle doors is opened, the lock instruction operation is canceled as an invalid operation.

  Therefore, even if the user of the portable device performs a locking operation using, for example, a lock switch provided on the portable device, if there is a vehicle door that is not yet closed when another occupant is getting off, Cannot be locked, and the lock switch must be operated again after the other passengers get off the vehicle and the vehicle door is closed. In recent years, a slide door or a back door having an automatic opening / closing function is often provided in a vehicle, and it may take time until all the vehicle doors are closed. In such a case, the user carrying the portable device must wait for an appropriate time until all the doors are closed.

  The present invention has been made in view of the above points, and allows a user to perform a locking operation even when any of the vehicle doors is not closed, and allows the locking operation to be accepted and locked. It is an object of the present invention to provide a vehicle door control system that allows a user to reliably confirm that this is the case.

In order to achieve the above object, in the vehicle door control system according to claim 1, the in-vehicle device is:
Lock reservation means for storing that a lock is reserved when a lock operation is performed by a user in a state where any vehicle door in the vehicle is open;
When a lock reservation is stored by the lock reservation means, using an in-vehicle device mounted on the vehicle, a first answer back means for performing an answer back in the first mode;
All door locking means for locking all vehicle doors in the vehicle when the opened vehicle door is closed in the state where the lock reservation is stored by the lock reservation means;
When all the vehicle doors are locked by the all door locking means, a second answer back means is provided that performs answer back in a second mode different from the first mode using an in-vehicle device. And

  In the vehicle door control system according to claim 1, as described above, the lock is reserved when the in-vehicle device is locked by the user while any of the vehicle doors is open. Lock reservation means for storing. Then, when the opened vehicle door is closed while the lock reservation is stored, all the door locking means locks all the vehicle doors in the vehicle. Therefore, the user of the portable device does not need to wait for the lock operation until all the doors are closed, and can perform the lock operation even when one of the doors is opened, thereby improving user convenience. And a first answer back means for performing answer back in the first mode using an in-vehicle device (for example, a buzzer and / or a hazard lamp) mounted on the vehicle when a lock reservation is stored. ing. Therefore, the user can confirm that the lock operation performed by the user is accepted by the answerback of the first aspect. Further, the in-vehicle device also includes a second answer back means for performing answer back in a second mode different from the first mode when all vehicle doors are locked by the all door lock unit based on the lock reservation. I have. Therefore, the user can surely confirm that all the vehicle doors are locked by the answer back of the second aspect different from the first aspect.

  As described in claim 2, the portable device is provided with the first lock switch for the lock operation, and when the first lock switch is operated, the lock switch operation signal is received from the portable device. When the vehicle switch receives a lock switch operation signal when any vehicle door is open, it stores the lock reservation and when all vehicle doors are closed, the lock switch operation signal May be configured to immediately lock all vehicle doors. That is, the vehicle door control system can be embodied as a keyless entry system, and in this case, the user can perform a locking operation with the first lock switch provided in the portable device.

  As described in claim 3, the portable device and the vehicle-mounted device are bidirectional in which the portable device returns a response signal including an ID code in response to a transmission request signal from the vehicle-mounted device in a predetermined communication area around the vehicle. When the vehicle-mounted device receives an ID code corresponding to a pre-registered ID code from the portable device, a lock operation by the user using the second lock switch provided on the vehicle door is performed. The vehicle-mounted device stores the lock reservation when a lock operation is performed when any vehicle door is open, and the lock operation is performed when all vehicle doors are closed. It may be configured to immediately lock all vehicle doors. That is, the vehicle door control system can be embodied as a smart entry system. In this case, the user is provided on the vehicle door on the condition that the ID code is authenticated in the in-vehicle device. The lock operation can be performed by the second lock switch.

  As described in claim 4, when the lock reservation means stores the lock reservation, the in-vehicle device performs bidirectional communication with the portable device, and whether or not communication with the portable device is possible. Accordingly, the length of the distance from the vehicle of the user carrying the portable device is determined, and the first answerback means determines whether the answerback using the in-vehicle device is based on whether the distance from the vehicle to the user is long or short. One aspect may be different from each other. For example, when the user is at a short distance from the vehicle, the user performs an answer back with only the buzzer, reduces the volume of the buzzer, reduces the number of buzzers and / or blinks the hazard lamp, When the user is at a long distance from the vehicle, the answer back may be performed using only the hazard lamp, the volume of the buzzer may be increased, the number of buzzer sounds and / or the number of blinking hazard lamps may be increased. Thereby, the user can perform an answerback in a mode in which it is possible to reliably confirm that the lock operation has been performed regardless of the distance from the vehicle.

  Further, as described in claim 5, when the all door lock means locks all the vehicle doors based on the lock reservation, the in-vehicle device performs bidirectional communication with the portable device, The second answer back means determines whether the distance from the vehicle of the user carrying the portable device to the user is long or short depending on whether or not the communication is possible. The second aspect of the answerback using the in-vehicle device may be different from each other. Thereby, the user can perform an answer back in a mode in which it is possible to reliably confirm that all the vehicle doors are locked regardless of the distance from the vehicle.

  As described in claim 6, when all the door locking means locks all the vehicle doors based on the lock reservation, the in-vehicle device transmits the result of whether or not the locking is completed to the portable device, The portable device preferably notifies the transmitted result. Thereby, the user can confirm whether the lock | rock of the vehicle door was completed more reliably and easily.

  As described in claim 7, it is preferable that the first and second aspects of the answerback using the in-vehicle device by the first and second answerback means can be customized by the user. Accordingly, the answer back mode can be set so that an appropriate answer back is performed in consideration of the user's living environment and the parking place environment.

  Hereinafter, an embodiment of a vehicle door control system according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an overall configuration of a vehicle door control system 1 according to the present embodiment. The vehicle door control system 1 according to this embodiment includes a function of a so-called smart entry system that uses wireless bidirectional communication between an electronic key 200 as a portable device and a vehicle-side device 100 as an in-vehicle device, and an electronic key. By operating a switch provided in 200, a one-way communication is performed from the electronic key 200 to the vehicle side device 100, and a function of a so-called keyless entry system for controlling locking / unlocking of the vehicle door is provided.

  As shown in FIG. 1, the vehicle door control system 1 according to the present embodiment includes a vehicle side device 100 mounted on a vehicle (not shown) and an electronic key 200 carried by the user. 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 mainly uses the vehicle interior as a communication area with the electronic key 200. Therefore, whether or not the electronic key 200 exists in the vehicle interior can be detected based on whether or not communication with the electronic key 200 using the vehicle interior transmitter 102 is possible.

  The vehicle interior transmitter 104 is shown as a single transmitter in FIG. 1 for convenience of illustration, but in practice, it is composed of, for example, 5 vehicle interior transmitters. That is, the transmitter 104 outside the vehicle includes a right front door (hereinafter also referred to as a D seat door), a right rear door (hereinafter also referred to as a DR seat door), a left front door (hereinafter also referred to as a P seat door), a left rear door ( Hereinafter, it is provided on each of the doors) and the back door, and a communication area with the electronic key 200 within a predetermined range (1-2 m) is formed around each door. When the electronic key 200 enters the communication area of any one of the vehicle exterior transmitters 104, bidirectional communication with the electronic key 200 becomes possible. Therefore, it is possible to detect which door the user carrying the electronic key 200 is approaching depending on which of the vehicle interior transmitters 104 the electronic key 200 communicates with.

  Further, as shown in FIG. 1, the vehicle-side device 100 has a verification ECU 108. The verification ECU 108 is a general computer including a CPU, a memory, and the like, and is included in a bidirectional communication process with the electronic key 200 and a signal received from the electronic key 200 according to a program stored in advance in the memory. The ID code matching process is executed, and a door lock / unlock instruction signal, an answer back instruction signal, and the like are output to a body ECU 110 described later.

  For example, when the vehicle is parked and the vehicle door is locked (locked), the verification ECU 108 outputs a transmission request signal to the vehicle interior transmitter 104 at predetermined intervals. When the transmission request signal is output from the verification ECU 108, the out-of-vehicle transmitter 104 transmits the transmission request signal to each communication area. When the electronic key 200 is present in the communication 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 a response signal returned from the electronic key 200 as described above. The receiver 106 also receives an unlocking signal (unlock switch operation signal) and a locking signal (lock switch operation signal) 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 unlock signal, and the lock signal to the verification ECU 108.

  The verification ECU 108 outputs a transmission request signal to each outdoor transmitter 104 so that the transmission request signal is sequentially transmitted from each of the outdoor transmitters 104 at different timings. Therefore, the verification ECU 108 can determine from which communication area the response signal is transmitted from the time when the response signal is received. The transmission request signal transmitted from each vehicle interior transmitter 104 includes a code unique to each vehicle exterior transmitter 104, and the response signal returned from the electronic key 200 also includes the response signal of the vehicle exterior transmitter 104. By including the unique code, it is also possible to determine in which communication area the electronic key 200 exists.

  As described above, the response signal given to the verification ECU 108 includes the ID code of the electronic key 200 that returned the response signal. Verification ECU 108 determines whether or not the ID code included in the response signal corresponds to a registered ID code registered in advance. When the ID code of the response signal corresponds to the registered ID code, collation of the ID code is completed, and the electronic key 200 existing in the communication area is regarded as a regular electronic key. When the collation ECU 108 completes collation of the ID code, a door lock / unlock instruction signal, an answer back instruction signal, and the like are output to the body ECU 110 based on the collation result.

  The body ECU 110 controls driving of various devices equipped in the vehicle, and outputs detection signals from switches and sensors provided at various places to the verification ECU 108.

  For example, the vehicle side device 100 has a touch sensor 112 as shown in FIG. The touch sensor 112 is provided on each door outside handle (not shown, hereinafter referred to as a door handle) of each door (D seat door, P seat door, DR seat door, PR seat door, etc.) of the vehicle. When it is detected by the touch sensor 112 that the user carrying the electronic key 200 has touched the door handle, the body ECU 110 outputs a door handle operation detection signal to the verification ECU 108.

  At this time, when the collation ECU 108 completes collation of the ID code, the collation ECU 108 outputs a door unlock instruction signal to the body ECU 110. Based on the unlock instruction signal, the body ECU 110 drives the door lock mechanism 116 to unlock all the doors. The door lock mechanism 116 can unlock (unlock) the door based on the unlock instruction signal from the body ECU 110, and can lock (lock) the door based on the lock instruction signal. It is possible.

  A lock switch 114 is provided near the door handle. When the lock switch 114 is operated by the user, the body ECU 110 outputs a lock switch operation signal to the verification ECU 108. Then, the verification ECU 108 attempts bidirectional communication with the electronic key 200 using the vehicle interior transmitter 102 and the vehicle interior transmitter 104. At this time, when the two-way communication with the electronic key 200 is not performed with the vehicle interior transmitter 102 but only with the vehicle interior transmitter 104, the electronic key 200 is left behind in the vehicle interior. It can be regarded as being carried by the user without being carried out. Then, when the ID code is verified through two-way communication with the outside transmitter 104, a lock reservation is stored or each door is actually locked according to the open / closed state of the door at that time. To do. The door lock control will be described in detail later.

  The hazard lamp 118 and the buzzer 120 are driven in accordance with a drive signal from the body ECU 110 based on the answer back instruction signal from the verification ECU 108, and the above-described lock reservation is stored when the door is locked / unlocked. Sometimes, it is used to implement an answer-back in various manners to inform the user of the electronic key 200 that each operation has been performed. The courtesy switch 122 detects the open / closed state of each door and inputs the detection signal to the body ECU 110.

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

  The receiving unit 202 receives transmission request signals transmitted from the vehicle interior transmitter 102 and the vehicle exterior transmitter 104 and outputs the received transmission request signals to the ECU 206. The unlock switch 208 is a switch operated when the user instructs to unlock the door. When the unlock switch 208 is operated, an unlock switch signal is input to the ECU 206. The lock switch 210 is a switch that is operated when the user instructs to lock the door. When the lock switch 210 is operated, a lock switch signal is input to the ECU 206.

  When the transmission request signal is input from the reception unit 202, the ECU 206 generates a response signal including the ID code of the electronic key 200 and transmits the response signal from the transmission unit 204 (wireless two-way communication). In addition, when an unlock switch signal is input from the unlock switch 208, the ECU 206 causes the transmission unit 204 to transmit an unlock switch operation signal (unlock signal) indicating that the unlock operation has been performed. When a lock switch signal is input from 210, a lock switch operation signal (locking signal) indicating that a lock operation has been performed is transmitted from the transmission unit 204 (wireless one-way communication).

  The unlock switch operation signal and the lock switch operation signal transmitted from the transmission unit 204 also include an ID code unique to the electronic key 200, and the ID code is verified by the verification ECU 108 of the vehicle side device 100. When this happens, the vehicle-side device 100 performs an operation corresponding to the unlock switch operation signal or the lock switch operation signal. Further, as described above, the communication area of the vehicle interior transmitter 104 of the vehicle side device 100 is set to a predetermined range around each door, but as shown in FIG. When the unlock switch 208 or the lock switch 210 provided on the electronic key 200 is operated, the communication range (for example, 10 to 15 m) of the unlock switch operation signal and the lock switch operation signal transmitted from the electronic key 200 Is more widely set.

  Since the vehicle door control system having the above-described configuration has a feature in a control method when locking each door of the vehicle, hereinafter, the flowchart of FIG. 3 regarding the door lock control performed in the verification ECU 108 and the body ECU 110. This will be described in detail based on Note that the process shown in the flowchart of FIG. 3 is repeatedly executed at predetermined time intervals until all doors are locked.

  First, in step S100, for example, it is determined based on a detection signal from the courtesy switch 122 whether any of the doors in the vehicle is open for the passenger to get off the vehicle or to take out the luggage. To do. In this determination process, if it is determined that any door is open, the process proceeds to step S110. If it is determined that all the doors are closed, the process proceeds to step S170.

  In step S110, a lock request by the smart entry system, that is, whether the user carrying the electronic key 200 operates a lock switch provided near the door handle, determines whether or not a lock operation has been performed. . If it is determined in this determination process that the locking operation has been performed, the process proceeds to step S120. If it is determined that the locking operation has not been performed, the process proceeds to step S140.

  In step S120, one of the doors in the vehicle is still open, and the door cannot be locked immediately. Therefore, the lock reservation for reserving the doors when all the doors are closed is stored. To do. In step S130, the hazard lamp 118 and / or the buzzer 120 are used to notify a user or the like carrying the electronic key 200 that a lock reservation has been made using the function of the smart entry system. A first answer back A is performed.

  In step S140 executed when a negative determination is made in step S110, whether or not the lock operation by the keyless entry system, that is, whether or not the lock operation has been performed by the user operating the lock switch 210 of the electronic key 200 is determined. Determine. In this determination process, if the lock switch operation signal is received by the receiver 106 and it is determined that the lock operation has been performed, the process proceeds to step S150. On the other hand, if it is determined that the lock operation has not been performed, the process is temporarily terminated.

  In step S150, similarly to step S120, a lock reservation for reserving to lock the doors when all the doors are closed is stored. In step S160, in order to notify the user of the electronic key 200 that the lock reservation has been made using the function of the keyless entry system, the second answer is used using the hazard lamp 118 and / or the buzzer 120. Back B is performed.

  In this embodiment, the answer back mode is different between when the lock reservation is made using the function of the smart entry system and when the lock reservation is made using the function of the keyless entry system. (The first answer back A and the second answer back B) may be performed in the same manner. Further, when changing the answer back mode between the first answer back A and the second answer back B, the buzzer sounding time and number of times of sounding, the lighting time of the hazard lamp and the number of times of blinking may be changed. .

  In step S170, which is executed when it is determined in step S100 that all doors are closed, it is determined whether a lock reservation is stored. If the lock reservation is stored, the process proceeds to step S180. If the lock reservation is not stored, the process proceeds to step S230.

  In step S180, it is determined whether or not all the doors have already been locked. If they have been completed, the process ends. On the other hand, if it is determined that the door is not yet locked, the process proceeds to step S190, where a lock instruction signal is output to the door lock mechanism 116, and all the doors are locked.

  Conventionally, even if the above-described locking operation is performed in a state where any door of the vehicle is opened, the locking operation is canceled as an invalid operation. For this reason, the user carrying the electronic key 200 has to wait until all the doors are closed, and then perform a lock operation again.

  On the other hand, in this embodiment, when a lock operation is performed by the user in a state where any door is open, a lock reservation indicating that a lock is reserved is stored. When all the doors are closed with the lock reservation stored, all the doors in the vehicle are locked. Therefore, the user carrying the electronic key 200 does not have to wait for the lock operation until all the doors are closed, and can perform the lock operation even when any door is opened. Can be improved.

  In the subsequent step S200, a transmission request signal is transmitted from the vehicle interior transmitter 104 to determine whether or not bidirectional communication with the electronic key 200 is possible. That is, when a response signal is received from the electronic key 200, bidirectional communication is possible, and when it is not received, it is determined that bidirectional communication is impossible. By this determination process, the length of the distance from the vehicle of the user carrying the electronic key 200 can be determined. That is, as described above, since the communication area for bidirectional communication using the vehicle interior transmitter 104 is determined in the processing range in the vicinity of each door, when the bidirectional communication is possible, the user If the vehicle exists within a short distance from the vehicle and bi-directional communication is impossible, it can be considered that the user exists within a long distance from the vehicle.

  If it is determined in step S200 that two-way communication is possible and the user is within a short distance from the vehicle, the electronic key 200 is carried in step S210 to indicate that all the doors of the vehicle are locked. The third answer back C is performed using the hazard lamp 118 and / or the buzzer 120 in order to notify a user who is present. On the other hand, if it is determined in step S200 that two-way communication is not possible and the user is within a long distance from the vehicle, the fourth answer back is used in step S220 using the hazard lamp 118 and / or the buzzer 120. Do D.

  Here, for example, in the third answer back C when the user is at a short distance from the vehicle, the answer back is performed only with the buzzer, the volume of the buzzer is reduced, the number of buzzer sounds and / or the hazard lamp In the fourth answer back D when the user is at a long distance from the vehicle while reducing the number of blinks, the answer back is performed only with the hazard lamp, the buzzer volume is increased, the number of buzzer sounds and / or Increase the number of blinking hazard lamps. Thereby, regardless of the distance from the vehicle, the user can surely confirm that all the doors of the vehicle are locked, and the answer back can be performed in a manner that does not disturb the surroundings.

  Further, as described above, in the present embodiment, the first and second answerbacks A and B when the lock reservation is made and when all the doors are actually locked based on the lock reservation. The third and fourth answer backs C and D are different. Therefore, the user carrying the electronic key 200 distinguishes that the lock operation performed by the user is accepted and that all doors are locked based on the lock reservation. Can be recognized reliably.

  In step S230 executed when it is determined in step S170 that the lock reservation is not stored, the lock request using the function of the smart entry system or the lock using the function of the keyless entry system is performed as in the conventional case. Determine if there is a request. If it is determined that there is a lock request, in step S240, a lock instruction signal is output to the door lock mechanism 116 to lock all doors. In a subsequent step S250, a fifth answer back E is performed to notify the user that all the doors have been locked.

  The fifth answer back E may be different from the third and fourth answer backs C and D described above, or may be the same as the third answer back C or the fourth answer back D. good. Furthermore, when it is determined in step S230 that there is a lock request, the same processing as in step S200 described above is performed to determine the length of the distance from the user's vehicle. The answer back C may be executed, and the fourth answer back D may be executed when the distance is long.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. is there.

  For example, in the above-described embodiment, when the user performs a lock operation using the function of the keyless entry system, the second answer back B is implemented to notify that a lock reservation has been made. However, when the user performs a lock operation using the function of the keyless entry system, the user may be in the vicinity of the vehicle or in a remote position. For this reason, when the lock operation is performed using the function of the keyless entry system, the length of the distance from the user's vehicle is determined depending on whether or not the two-way communication with the electronic key 200 is possible. Depending on the length of the distance, the mode of the second answer back B may be different from each other like the answer back B1 and the answer back B2.

  In addition, the electronic key 200 is provided with a display and the like, and the vehicle side device 100 is configured to be able to transmit that the door of the vehicle is locked from the vehicle side device 100 to the electronic key 200. When all the doors are locked, a result indicating whether or not the locking is completed may be transmitted to the electronic key 200, and the electronic key 200 may notify the transmitted result by a display or the like. Thereby, the user can confirm more reliably and easily whether the lock | rock of the door in a vehicle was completed.

  Furthermore, the first to fifth answerbacks A to E described above may be configured to be customizable by the user. Accordingly, the user can set the answer back mode so that an appropriate answer back is performed in consideration of the living environment, the parking environment, and the like.
