Here, the door lock switch 14 is disposed in a vehicle interior trim or the like, and drives the door lock device 6 during a pressing operation by an occupant or the like to lock the vehicle door. The door opening / closing switch 15 detects whether or not the vehicle door is closed at a proper position.

  The receiving unit 2 is installed in the vehicle compartment and connected to the display unit 16 that displays the registration authentication information 102. In the present embodiment, the registration authentication information 102 includes number information 102 a regarding a plurality of digits, and the digits of each digit are displayed on the display unit 16 when the registration authentication information 102 is stored. In the present embodiment, the registration authentication information 102 is a combination of four pieces of number information 102a composed of 8-digit numbers. Each digit of the number information 102a is treated as partial information 102b obtained by dividing the registration authentication information 102 for each digit. The display unit 16 may use a monitor or the like installed in the vehicle, or may be connected to the receiving unit 2 only when the registration authentication information 102 is registered.

  The receiving unit 2 is connected to the security system 17. That is, when the door operation information 101 is transmitted from the transmitter 3 to the receiving unit 2, the security system 17 is set to an armed state or a disarmed state as necessary. The security system 17 has the same configuration as that of a conventionally known one, and a description thereof is omitted here.

  The transmitter 3 transmits the unique authentication information 103 together with the door operation information 101. The unique authentication information 103 is set so as to correspond to the above-described registration authentication information 102, and includes number information 103a related to a multi-digit number. As shown in FIG. 2, the storage unit 8 of the receiving unit 2 stores an authentication determination program 111 that determines whether or not the unique authentication information 103 and the registered authentication information 102 match. If it is determined by the authentication determination program 111 that the unique authentication information 103 and the registered authentication information 102 match, the door operation program 112 is allowed to drive the door lock control unit 5 and the answer back control unit 12. It has become. The answer back control unit 12 controls the answer back buzzer 10 and the answer back lamp 11 based on the customization information 104.

  As shown in FIG. 3, a code label 3 c is affixed to the transmitter 3. In this code label 3c, four number information 103a in the unique authentication information 103 unique to the transmitter 3 is described. The code label 3c may not be directly attached to the transmitter 3. That is, for example, it may be described on a key holder of the transmitter 3 or a packing material of the transmitter 3.

  The storage unit 8 of the receiving unit 2 stores an authentication storage program 113 for storing the registration authentication information 102 based on the operation state of the buttons 3a and 3b of the transmitter 3. The receiving unit 2 is configured to permit storage of the registration authentication information 102 when a predetermined registration permission signal is received. In the present embodiment, this registration permission signal includes an ON signal for the ignition switch 13 and the like, and the registration operator turns the ignition switch 13 by turning the key inserted into the key cylinder. By including the registration mode transition operation, it is possible to shift to the registration mode so that the registration authentication information 102 can be stored. When storing the registration authentication information 102, the registration operator presses the buttons 3a and 3b of the transmitter 3 to determine the numbers of the digits of the number information 102a. In addition to the registration authentication information 102, customization information 104 regarding the door lock answer back is also stored.

  In this embodiment, the number of each digit is increased when the lock button 3a as the number change button is pressed, and the number at the corresponding digit is determined when the unlock button 3b as the number determination button is pressed. Further, the registration authentication information 102 is stored in the receiving unit 2 by causing the receiving unit 2 to sequentially receive each piece of partial information 102b consisting of a single digit.

  The storage unit 8 stores a notification program 114 for notifying that the reception of the partial information 102b in the receiving unit 2 is completed for each partial information 102b. In the present embodiment, notification is made using the answer back buzzer 10 and the answer back lamp 11, and the calculation unit 7, the storage unit 8, the answer back buzzer 10 and the answer back lamp 11 serve as notification means.

  The operation of the receiving unit 2 when storing the authentication registration information 102 in the keyless entry device 1 configured as described above will be described with reference to the flowchart of FIG.

  First, the vehicle user performs an operation of the ignition switch 13 for shifting to the registration mode, an opening / closing operation of a door such as a driver's seat, or a combination of these operations, and receives a predetermined registration permission signal from the outside. It is determined whether or not (step S1). In this embodiment, first, after the driver's seat door of the vehicle is opened and closed by a registered worker and an output signal is received from the door open / close switch 15, the ignition switch 13 is turned ON / OFF 10 times within 15 seconds. When the key is operated and the predetermined signal is received, the receiving unit 2 sounds the answer back buzzer 10 and informs the answer back in order to notify the registration worker that the preparation for shifting to the registration mode is completed. The lamp 11 blinks. In this state, when the registration operator further opens and closes the driver's seat door, the receiving unit 2 determines that all operations for shifting to the registration mode have been performed.

  If it is determined in step S1 that an operation or the like for shifting to the registration mode has been performed, the mode shifts to the registration mode and the registration authentication information 102 can be stored (step S2). If it is not determined in step 1 that an operation for shifting to the registration mode has been performed, the process returns to step S1 and enters a standby state.

  After the registration authentication information 102 becomes storable in step S2, it is determined whether or not the first number information 102a of the registration authentication information 102 has been input by operating the door lock switch 14 (step S3). ). In the present embodiment, the number of each digit is increased by the time when the lock button 3a is pressed. Specifically, when a predetermined time elapses after the pressing of the lock button 3a, the answer back buzzer 10 sounds intermittently and the answer back lamp 11 blinks. The registered worker can identify the number based on the number of times the back buzzer 10 is blown and the number of times the answer back lamp 11 is turned on.

  Thus, after changing the number by pressing the lock button 3a, the number of each digit is determined by pressing the unlock button 3b. That is, by repeating the operation of each button 3a, 3b eight times, all eight digits of the number information 102a are determined. In the present embodiment, when detecting the pressing operation of the unlock button 3b, the receiving unit 2 confirms that the digit of the digit has been determined by blowing the answer back buzzer 10 and lighting the answer back lamp 11. The registration worker is notified by performing it once for a predetermined time. In the present embodiment, since the 8-digit number being registered is displayed in real time on the display unit 16, the registration operator can also identify the number. . Furthermore, in this embodiment, the registration worker can directly recognize the number information 102a to be registered by the code label 3c of the transmitter 3. When the transmitter 3 does not exist in the vehicle, the number information 102a unique to the vehicle can be recognized and registered from data managed by a factory, a store, or the like.

  If it is determined in step S3 that the first number information 102a has been input, the number information 102a is stored in the storage unit 8 (step S4). In this embodiment, at this time, the answer back buzzer 10 is sounded twice and the answer back lamp 11 is blinked twice. Thereby, the registration worker can recognize that the first number information 102a is stored. The sounding time and lighting time are set longer than the sounding time and lighting time at the time of operation input by the lock button 3a. If it is not determined in step S3 that the first number information 102a has been input, the process returns to step S3 to enter an input standby state.

  Thereafter, it is determined whether or not the vehicle door has been opened and closed (step S5). If it is determined that the vehicle has been opened and closed, the second number information 102a is stored (step S6). If there is no opening / closing operation of the vehicle door, the process returns to step S5 and enters a standby state. After step S6, it is determined whether or not the second number information 102a of the registration authentication information 102 has been input by operating the buttons 3a and 3b of the transmitter 3 (step S7). Note that the operation of the receiving unit 2 when storing the second number information 102a in the storage unit 8 is the same as when the first number information 102a is input, and thus description thereof is omitted here.

  If it is determined in step S7 that the second number information 102a has been input, the number information 102a is stored in the storage unit 8 (step S8). Also at this time, using the answer back buzzer 10 and the answer back lamp 11, the registered worker is notified that the numerical information 102a has been stored.

  Then, it is determined again whether or not the vehicle door has been opened and closed (step S9). In this way, the third and fourth number information 102a is also stored in the same operation as the first and second number information 102a (steps S10 to S17).

  After the first to fourth number information 102a is registered, the customization information 104 is subsequently stored (step S18). In the present embodiment, an answer back pattern can be selected from among several types using the door lock switch 14.

  Thereafter, it is determined whether or not the key has been removed from the key cylinder (step S19). When it is determined that the key is removed from the key cylinder, the mode returns from the registration mode to the normal mode (step S20). In the present embodiment, when returning to the normal mode, the answer back buzzer 10 is sounded three times and the answer back lamp 11 is blinked three times. The sounding time and lighting time are the same as the sounding time and lighting time when each piece of information 102a is stored.

  Thus, according to the keyless entry device 1 of the present embodiment, when the registration authentication information 102 is stored in the reception unit 2, the registration authentication information 102 is not received by the reception unit 2 in a lump but is divided into a plurality of pieces. The registered authentication information 102 is entirely stored in the receiving unit 2 by causing the receiving unit 2 to sequentially receive the partial information 102b.

  Therefore, even if the registration authentication information 102 is transmitted to the receiving unit 2 by a third party or the like who aims for theft, the receiving unit 2 is set to receive sequentially in the state of the divided partial information 102b. Therefore, the registration authentication information 102 is not rewritten. As a result, the security is remarkably improved as compared with the conventional one in which the authentication information is registered using the transmitter 3 without providing a special protection function.

  In addition, according to the keyless entry device 1 of the present embodiment, the unique authentication information 103 and the registered authentication information 102 are number information 103a and 102a, so that management of information is convenient. The partial information 102b can be easily generated by dividing the number of digits.

  Further, according to the keyless entry device 1 of the present embodiment, every time reception of the partial information 102b in the reception unit 2 is completed, the reception completion is notified to the registration worker by the answer back buzzer 10 and the answer back lamp 11. Informed. Accordingly, the registration worker may complete the input of the first partial information 102b and input the second partial information 102b, or the input of the first partial information 102b may be completed due to, for example, a communication failure or an input error. It is possible to recognize whether it is necessary to input again.

  Further, according to the keyless entry device 1 of the present embodiment, since the display unit 16 is provided, the registration worker visually recognizes the number information 102a of the registration authentication information 102 by the display unit 16 when the registration authentication information 102 is stored. Registration work can be done. As a result, the burden on the registration worker can be reduced, and accurate registration authentication information 102 can be accurately registered.

  Further, according to the keyless entry device 1 of the present embodiment, the registration authentication information is obtained by operating the buttons 3a and 3b of the transmitter 3 for the number of digits of the number information 102a of the registration authentication information 102, that is, only eight times. All the numbers of each digit of 102 are determined, and the number information 102a of the registration authentication information 102 is determined. As a result, the registration work becomes complicated and the registration authentication information 102 of the receiving unit 2 cannot be easily rewritten. Accordingly, it is possible to prevent rewriting of the registration authentication information 102 by a third party or the like aiming at theft.

  In addition, according to the keyless entry device 1 of the present embodiment, the digits of each digit are determined by the pressing time of the lock button 3a, so that complicated registration work is not necessary, and the registration worker does not get lost in the input operation. You can register.

  Further, according to the keyless entry device 1 of the present embodiment, each button 3a provided in the transmitter 3 is used by using the lock button 3a for changing numbers and using the unlock button 3b for determining numbers. , 3b can be used effectively. Moreover, since the input operation of the number information 102a is relatively simple, the burden on the registration worker can be further reduced.

  Further, according to the keyless entry device 1 of the present embodiment, the registration authentication information 102 cannot be stored unless a predetermined registration permission signal is received. Therefore, the security is further improved by setting the registration permission signal separately for each vehicle. Further, for example, a predetermined registration permission signal may be transmitted from the immobilizer device, or a predetermined registration permission signal may be transmitted when the vehicle user's unique password is input from the failure diagnosis device or the like.

  Further, according to the keyless entry device 1 of the present embodiment, when the registration authentication information 102 is stored in the receiving unit 2, the customization information 104 related to the door lock answerback is stored together with the registration authentication information 102. The registration authentication information 102 and the door lock answer back function can be set at the same time, and these settings can be performed once, which is very convenient.

  Further, according to the keyless entry device 1 of the present embodiment, even if the transmitter 3 to be registered in the receiving unit 2 is not at hand, the receiving authentication information 102 is received by the receiving unit 2 using the separate transmitter 3. The registration authentication information 102 can be stored in the receiving unit 2.

  In the above-described embodiment, the number of the number information 102a is increased according to the time when the door lock switch 14 as the operation switch is pressed, but the number of times the door lock switch 14 is pressed is shown. The number information 102a may be determined so that each digit number is determined. Also in this case, no complicated registration work is required, and the registration worker can perform registration without hesitation in the input operation.

  In the embodiment, the registration authentication information 102 includes the number information 102a. However, the registration authentication information 102 may not include the number information 102a. Further, although the partial information 102b is shown as a number for each digit, the partial information 102b may be a number with at least one digit. That is, the partial information 102b may be a multi-digit number. Furthermore, when a plurality of registration authentication information 102 includes a plurality of pieces of number information 102a as in the above-described embodiment, each piece of number information 102a may be handled as partial information 102b.

  In the embodiment, the customization information 104 is stored with the registration authentication information 102. However, the customization information 104 may be stored in the storage unit 8 separately from the registration authentication information 102. . Further, it is needless to say that the answer back function may not be provided.

  Moreover, in the said embodiment, although what displayed the numerical information 102a on the display part 16 was shown, of course, it is good also as a structure which does not provide the display part 16. FIG. In this case, the registered worker recognizes the numbers using the answer back buzzer 10, the answer back lamp 11, and the like.

  Moreover, in the said embodiment, when the lock button 3a of the transmitter 3 was pressed, the number of each digit of the number information 102a was increased, and when the unlock button 3b was pressed, the number was determined. Of course, the number may be increased by 3b and the number may be determined by the lock button 3a. That is, the number increases when one of the buttons 3a and 3b is pressed, and the number is determined when the other is pressed.

  In the above embodiment, the registration authentication information 102 is registered using the buttons 3a and 3b of the transmitter 3. However, the operation switch installed in the vehicle compartment is provided independently of the vehicle. In addition, the registration authentication information 102 may be registered using a failure diagnosis device that diagnoses a failure of the receiving unit 2, and other specific detailed structures can be changed as appropriate. Of course.

  In the above embodiment, the receiver unit 2 is shifted to the registration mode by operating the ignition switch 13 or the like. However, the transmitter 3 may be shifted to the registration mode. That is, when the registration authentication information 102 is stored in the receiving unit 2 by using the authorized transmitter 3 corresponding to the receiving unit 2 by adding the function of the registration mode transition to the transmitter 3 as well, the operator registration is performed. Work efficiency can be improved.

  Here, for example, when the transmitter 3 shifts to the registration mode, whether the digits of the registration authentication information 102 determined by the operator by operation match the numbers stored in the transmitter 3. By providing the transmitter 3 with a function for determining whether or not, the operator may specify the number of each digit by, for example, pressing the lock button 3 a of the transmitter 3. At this time, the transmitter 3 collates the registration authentication information 102 held by the transmitter 3 itself with the number input by the operator, and if they match, the transmitter 3 lights up the indicator of the transmitter 3. Notify workers. Thus, it is very efficient for the operator to input the registration authentication information 102 while confirming the display of the indicator. Here, the collation result may be notified to the operator not by turning on the indicator but by sounding a buzzer.

  As described above, as a method for shifting the transmitter 3 and the reception unit 2 to the registration mode, operation switches installed in the vehicle compartment for the transmitter 3 and the reception unit 2 as in the above-described embodiment. (The ignition switch 13, the door lock switch 14, the door opening / closing switch 15 and the like) or the special operation by the lock button 3 and the unlock button 3b of the transmitter 3 may be used to shift to the individual registration mode.

  Further, when the keyless entry device 1 can exchange information bi-directionally, for example, like a smart entry device, the reception unit 2 is shifted to the registration mode to indicate that the reception unit 2 is in the registration mode. 3 side, and the transmitter 3 side may be shifted to the registration mode at the same time. At this time, of course, the receiving unit 2 may be shifted to the registration mode first. Thereby, the receiving unit 2 and the transmitter 3 can be shifted to the registration mode reliably and easily.
