BEST MODE FOR CARRYING OUT THE INVENTION

First Embodiment of the Invention FIG. 1 is an external view of a keyless remote controller (remote controller), FIG. 2 is a circuit diagram of the remote controller, and FIG. 3 is a circuit diagram of a keyless entry controller (vehicle controller) mounted on a vehicle. The keyless entry device according to one embodiment includes a remote controller 2 integrally formed with the key 1 shown in FIGS. 1 and 2 and a vehicle-mounted controller 3 shown in FIG. In this embodiment, a remote controller integrally formed with a key will be described as an example. However, a remote controller that is unitized separately from the key may be used.

As shown in FIG. 1, the head of the key 1 is provided with a door lock switch 1a and a door unlock switch 1b of a remote controller. A remote control 2 shown in FIG. When the lock switch 1a is operated, the remote controller 2 transmits the lock information and the ID set to the key 1 to lock / unlock the door without using the key, and the unlock switch 1b is operated. And the unlock information and the ID of the key 1 are transmitted.

The remote controller 2 is mainly composed of a controller 21 having a microcomputer, and controls communication with the on-board controller 3 shown in FIG. Controller 2
1 is an EEPRO in which a unique ID is stored for each key.
M and a non-volatile memory 22 and the door lock switch 1
a, door unlock switch 1b, and antenna 23
Is connected to the battery BAT.

The on-vehicle controller 3 is mainly composed of a controller 31 as shown in FIG. The controller 31 includes a microcomputer, its peripheral components, and a tuner 31a, and locks / unlocks a driver's door, a passenger's door, and left and right rear doors.
The tuner 31a reproduces the data sent from the remote controller 2. Numerals 32 to 35 denote door lock actuators of a driver's seat door, a passenger seat door, a rear seat right door, and a rear seat left door, respectively. The door lock actuators 32 to 35 drive a door lock mechanism (not shown) of each door to a lock side or an unlock side.

The lock relay 36 is driven by a transistor 37 and supplies the electric power of the battery BAT to the door lock actuator 32 to be driven to lock the driver's door. The output from the lock relay 36 to the actuator 32 is connected to the controller 31 in order to monitor the lock output to the door lock actuator 32. The unlock relay 38 is driven by the transistor 39 and supplies the power of the battery BAT to the door lock actuator 32 to unlock the driver's door. The output from the unlock relay 38 to the actuator 32 is connected to the controller 31 in order to monitor the unlock output to the door lock actuator 32.

The lock relay 41 is driven by a transistor 42 and supplies the power of the battery BAT to the door lock actuators 33 to 35 to be driven to lock the front passenger seat door and the rear left and right doors. Note that, in order to monitor the lock output to the door lock actuators 33 to 35, the lock relay 41 transmits the actuators 33 to 3 to each other.
The output to 5 is connected to controller 31. The unlock relay 43 is driven by a transistor 44,
Door lock actuator 3 for battery BAT
The power is supplied to 3-35 and driven to unlock the passenger's seat door and the rear left and right doors. In addition, in order to monitor the unlock output to the door lock actuators 33 to 35, the unlock relay 43 sends the actuators 33 to 3 to each other.
The output to 5 is connected to controller 31.

The controller 31 also has an antenna 4
5 and a nonvolatile memory 46 such as an EEPROM. The antenna 45 is installed in the rear window and receives a radio wave transmitted from the keyless remote controller 2.

The memory 46 stores the ID of the remote controller 2 as a registration ID.
To be stored. As shown in FIG. 4, up to four types (ID1 to ID4) can be registered in the ID registration area from address n to (n + 3) in the memory 46. Although this embodiment shows an example in which an EEPROM is used as the memory 46, another type of non-volatile memory may be used.

A switch and a lamp for detecting the state of each door are connected to the controller 31. A switch 47 is a driver door key cylinder lock switch that closes when the driver door key cylinder is in the lock position, and a switch 48 is a passenger door key cylinder lock switch that closes when the passenger door key cylinder is in the lock position. The switches 49 to 52 are door switches that are closed when the driver door, the passenger door, the rear right door, and the rear left door are open. Further, the switch 53 is a key switch that closes when the ignition key 1 is inserted into the key cylinder,
The switch 54 is an accessory switch that closes when the ignition key 1 is set to the ACC position. The lamp 55 is a hazard lamp and is used as an ID registration completion indicator in the ID registration mode.

Next, the format of data transmitted from the remote controller 2 will be described with reference to FIG. Transmission data is A
, B, and C data.
Part A is a data header, and part B is a control code for the lock switch 1a and the unlock switch 1b. In this embodiment, an example of a remote controller provided with a lock switch 1a and an unlock switch 1b is shown. However, in a remote controller provided with a trunk lid opener switch in addition to the lock / unlock switch, each operation switch is provided separately. Set the control code. C section is remote control 2
Is a unique ID code set in the.

In this embodiment, the ID registration method is changed depending on whether the data received from the remote controller 2 includes a door lock control code or a door unlock control code. When receiving the transmission data including the door lock control code, delete all the registered IDs,
Register a new ID. For example, as shown in FIG. 6A, in the ID registration mode, ID1 to ID4 are stored in the memory 46.
If the four types of IDs have already been registered, all of these registered IDs are deleted, and new IDs 5 and 6 are registered up to a maximum of four types as shown in (b) and (c). Note that the maximum ID registration type is not limited to four.

On the other hand, when the transmission data including the door unlock control code is received, the ID registered at the earliest time
Is deleted and a new ID is registered. For example, FIG.
In the ID registration mode, as shown in FIG.
Assuming that four types of IDs 1 to 4 have already been registered, the ID 1 registered at the earliest time among them is deleted, and a new ID 5 is registered as shown in (b).
When registering a new ID continuously, the ID2 registered at the earliest point in the registered IDs shown in (b) is deleted, and a new ID6 is registered as shown in (c).
In this registration method, the ID registered at the earliest point
Is deleted and a new ID is registered, so that this registration operation can be repeated many times. In this embodiment, the IDs are stored from the memory address n in the order of the earliest registration time. Every time a new ID is registered, the ID of the address n registered at the earliest time is erased and the remaining addresses ( IDs of (n + 1) to (n + 3) are moved up to addresses n to (n + 2), respectively.

FIG. 8 is a flowchart showing the ID registration mode processing of the first embodiment. The operation of the first embodiment will be described with reference to this flowchart. When a predetermined operation is performed, the in-vehicle controller 31 shifts to the ID registration mode. In this embodiment, the predetermined ID registration mode setting operation is an operation of setting the ignition key 1 to the ACC position after inserting and removing the ignition key 1 six times in 10 seconds. That is, the in-vehicle controller 31 sets the key switch 53 to “6” within 10 seconds.
When the accessory switch 54 is closed after repeating the closing and opening times, the ID registration mode is set and the processing shown in FIG. 6 is executed.

In step 1, reception of data including a door lock control code and an ID code from remote controller 2 is confirmed. If the received data includes the door lock control code, the process proceeds to step 2, where all registered IDs in the memory 46 are deleted. In the following step 3, the new ID is stored and registered in the address n of the memory 46, and in step 4, the hazard lamp 55 blinks twice to notify the completion of the registration. In step 5, reception of transmission data including the door lock control code and the ID code is confirmed again. If received, the process proceeds to step 6; otherwise, the process ends. In step 6, it is checked whether or not four new IDs have already been registered. If the new IDs have been registered, no more IDs can be registered, and the process ends. On the other hand, if there is room to register the ID, the process returns to step 3 and the above-described registration process is repeated.

If the data including the door lock control code has not been received, it is confirmed in step 7 that the data including the door unlock control code and the ID code has been received. If the received data includes the door unlock control code, the process proceeds to step 8 and the address n registered at the earliest time
Are erased, and addresses (n + 1) to (n
The IDs stored in (+3) are moved up to addresses n to (n + 2). In the next step 9, a new I
D is stored in the address (n + 3) of the memory 46, and in step 10, the hazard lamp 55 flashes to notify the completion of ID registration. In step 11, it is confirmed whether or not data including the door unlock control code and the ID code has been received again. If the data has been received, the process returns to step 8 to repeat the above-mentioned registration processing. If no data has been received, the processing ends.

As described above, when data is received from the remote controller when the ID registration mode is set, the reception ID is stored in the memory by the method corresponding to the operation information of the lock switch or the unlock switch included in the reception data.
It was made to remember as. That is, when the received data includes the operation information of the lock switch, all the registered IDs stored in the memory are deleted, the received ID is stored as the registered ID, and the unlocked data of the unlock switch is stored in the received data. If the operation information is included, the ID recorded at the earliest point among the registered IDs stored in the memory is deleted, and then the received ID is stored. As a result, by operating the lock switch or the unlock switch, the ID already registered at the time of registration of the new ID is set.
Can be selected as necessary, whether to delete all of them or part of them, and the operability can be improved.

-Modification of First Embodiment of the Invention-In the above-described first embodiment, when a door lock control code is received, all registered IDs are erased, a new ID is registered, and a door ID is registered. When the unlock control code is received, the ID registered at the earliest time among the registered IDs
Although D is deleted and a new ID is registered, the correspondence between the control code and the registration method may be reversed. That is, when the door unlock control code is received, the registered ID
Is deleted, and a new ID is registered. When the door lock control code is received, the ID registered at the earliest time among the registered IDs is deleted and a new ID is registered. In the case of a remote control having a trunk lid opener switch or other switches, the control code and I
The D registration method may be associated.

-Other Modifications of the First Embodiment of the Invention-In the above-described first embodiment, an example is shown in which the ID registered at the earliest time is deleted.
Other IDs may be deleted while leaving D. Normally, when the received ID is compared with the registered ID, the registered ID is temporarily transferred from the non-volatile memory to the RAM and compared, so that the most recently used ID always remains in the RAM. The other IDs may be deleted and left. Alternatively, each time the ID is compared, the memory addresses may be exchanged and rearranged in a new order at the time of use.

Second Embodiment of the Invention Next, a second embodiment of registering and erasing an ID using a tester for failure diagnosis will be described. FIG. 9 shows the configuration of the vehicle-mounted controller according to the second embodiment. Note that the same reference numerals are given to the same devices as those in the first embodiment shown in FIG. 3, and the description will focus on the differences. In the vehicle-mounted controller 3A according to the second embodiment, the controller 3
1 is connected to a failure diagnosis tester 61 to register and delete IDs.

FIG. 10 is a flowchart showing an ID registration / deletion process according to the second embodiment, and FIG. 11 is a diagram showing a display example of a monitor of the failure diagnosis tester 61. The controller 31 starts this processing when the tester 61 is connected and an ID registration command or an ID deletion command is sent.
When the power of the failure diagnosis tester 61 is turned on, a menu screen shown in FIG. 11A is displayed on the monitor of the tester 61. The monitor of the tester 61 is provided with a touch switch, and various switches can be configured on the monitor screen. By touching either “remote control ID deletion” or “remote control ID registration” on the menu screen of FIG. 11A, an ID registration command or an ID deletion command is sent to the controller 31.

In step 21, it is confirmed whether or not an ID erasing command has been received from the tester 61. In step 22, it is confirmed whether or not an execution command has been received. When the ID erasure is selected, an erasure confirmation screen shown in FIG. 11B is displayed on the monitor screen of the tester 61. Here, when "delete execution" is touched, an execution command is sent to the controller 31. The controller 31 that has received the execution command deletes all the registered IDs stored in the memory 46 in step 23,
In a succeeding step 24, an erasure completion signal is transmitted to the tester 61, and the process ends. The tester 61 that has received the erasure completion signal displays an erasure completion screen shown in FIG. 11C on the monitor.

On the other hand, when an ID registration command is received from the tester 61, the information of the registration ID stored in the memory 46 is transmitted to the tester 61 in step 25. The tester 61 displays the registration status of the ID as shown in FIG. This display example indicates that ID1 to ID3 have been registered and ID4 has not been registered. When any ID number is touched on this display screen, the touched ID is erased and a new ID is registered. For example, when deleting ID2 and replacing it with a new ID, touch “ID2” on the screen and select an unregistered ID.
When registering a new ID for No. 4, touch "ID4" on the screen. When one of the ID numbers is touched, the tester 61 stores the touched ID number in the controller 3.
1 and a registration message of a new ID as shown in FIG. 11 (e) is displayed on the monitor.

At step 26, the designated ID is received from the tester 61.
When the number is received, the process proceeds to step 27, where data including the ID code transmitted from the remote controller 2 is received. When the data including the ID code is received from the remote controller 2 in step 28, the process proceeds to step 29, where the received ID is stored and registered at the designated address of the memory 46, and the tester 61
Send the registered signal to. The tester 61 that has received the registering signal displays a message indicating that the ID is being registered as shown in FIG. Further, when the ID registration is completed in step 30, a completion signal is transmitted to the tester 61.
The tester 61 that has received the completion signal displays a registration completion message shown in FIG.

As described above, the ID registration mode is set by the failure diagnosis tester, and the ID registration method is selected. When data is received from the remote controller while the ID registration mode is set, the ID is selected by the failure diagnosis tester. The received ID is stored in the memory as the registered ID by the method described above. That is, a plurality of registrations I stored in the memory
D is deleted and then the reception ID is stored, or the registration ID to be deleted is specified and the reception ID is deleted.
Remember D. As a result, it is possible to select whether to delete all of the registered IDs or to delete a part of the IDs at the time of registration of a new ID by the failure diagnosis tester, as necessary. Can be improved.

In the configurations of the first and second embodiments and the modifications thereof, the lock switch 1a functions as the first operating member, the unlock switch 1b functions as the second operating member, The remote controller 2 constitutes a transmitting means, the antenna 45 and the tuner 31a constitute a receiving means, the nonvolatile memory 46 constitutes a storage means, the controller 31 constitutes a control means and a registering means, and the failure diagnosis tester 61 constitutes a registration method selecting means. .
