DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation of an ID setting change unit used for changing an ID setting in a keyless entry device for remotely controlling lock / unlock of a door by collating an ID without using a key. It has been improved.

[0002]

2. Description of the Related Art A keyless entry device has been put to practical use, in which a key is inserted into a key cylinder and turned, and a lock / unlock of a vehicle door and opening of a trunk lid are remotely controlled by collating an ID. I have. In this type of device, when a door lock switch, a door unlock switch, or a trunk opener switch provided on a keyless remote controller (hereinafter, referred to as a remote controller) is operated, information on the operated switch and a unique ID of the remote controller are transmitted. .

A keyless entry controller (hereinafter referred to as an onboard controller) on the vehicle side receives the switch information and the ID transmitted from the remote controller, checks the ID against a pre-registered ID, and if the IDs match, operates the switch. In response, doors are locked / unlocked and trunk lids are opened.

[0004] A predetermined number of IDs can be registered in the vehicle controller in advance. For the registered ID,
It can be deleted or changed. If there is free space in the memory, it is possible to register to add an ID. In such a conventional keyless entry device, there is a problem that operability is not good because switches connected to the controller are operated by a predetermined operation.

In order to solve this problem, the present applicant has disclosed in Japanese Patent Application Laid-Open No. 10-280758 a keyless entry system in which operations such as registration, change and deletion of an ID are performed by a setting change unit connected to a vehicle controller. The device was proposed. According to this method, erasure, change, and registration of an ID can be performed in an arbitrary memory, and operability is improved, for example, all operations are performed on a display screen.

[0006]

On the other hand, operability on a display screen is required for the purpose of further improving operability. In this regard, Japanese Patent Application Laid-Open No. 10-28075

And a vehicle-mounted controller that performs a process of performing ID processing, wherein an ID setting change unit that performs ID setting such as registration, change, and deletion of an ID in the memory on a display screen can be connected to the vehicle-mounted controller. Confirmation and erasure of the ID in the erasing operation of the above are performed on the same display screen.

According to a second aspect of the present invention, the ID stored in the memory is displayed as an ID number on an address key of the memory on the ID deletion screen.

According to a third aspect of the present invention, when the ID transmitted from the remote controller matches the ID stored in the memory, the address key of the memory storing the ID is displayed in reverse video. It was done.

According to a fourth aspect of the present invention, the reverse display of the address key is set within a predetermined time.

[0015]

According to the first aspect of the present invention, the ID confirmation and erasure in the ID erasing operation are performed on the same display screen. Therefore, after confirming the address of the memory storing the ID, the display screen is not changed. Can be erased. The effect of eliminating the trouble of changing the screen and preventing the address number from being forgotten or mistaken on the way is obtained.

In addition to the effect of the first aspect, in the second aspect of the invention, the ID stored in the memory is displayed as an ID number in an address key of the memory on the ID deletion screen. Therefore, just by looking at the display screen, the ID number can be confirmed and the memory to be stored can be confirmed.

In addition to the effect of the second aspect, according to the third aspect of the invention, when the ID transmitted from the remote controller matches the ID stored in the memory, the ID of the memory storing the ID is stored. Since the address keys are highlighted, it is possible to easily confirm in which memory the ID is stored.

In addition to the effect of the third aspect, in the invention of the fourth aspect, the reverse display of the ID number is set within a predetermined time, thereby indicating that the ID number is reversely displayed again and the operation is performed. be able to. For example, when an erasing operation is performed on an ID, the ID may be highlighted and displayed as an object to be erased to prompt confirmation. In this way, an effect of preventing erroneous erasure can be obtained.

A remote control ID confirmation / deletion screen is displayed to prompt the user to operate the remote control 2 and delete the ID. On this screen, the ID number stored in the address key of the memory is displayed. In the embodiment, ID1, ID2, ID1, and ID3 are stored in four address keys in order from left to right in the figure.

The remote controller 2 is operated to transmit, and the received ID received by the onboard controller is compared with the ID stored in the memory 46. If the reception ID is stored in the memory 46, in step 106, the stored address key of the memory 46 is highlighted for two seconds. Here, the ID number transmitted from the remote controller 2 is ID1, and the corresponding two address keys are highlighted. If the address key is not displayed in reverse, the reception ID is not stored in the memory 46, so the "end" key is pressed and the process returns to step 103 to display the remote controller ID setting change selection screen.

After the address key is highlighted for two seconds, the flow advances to step 107 to accept an ID erasing operation. Press the address key of the ID to be erased to erase the ID. Pressing the “All IDs” key will display all registered IDs.
Will be erased. To end ID deletion,
Press the "End" key to finish. The pressed address key is highlighted in step 108 for 2 seconds. Here, since the left address key storing ID1 is pressed, ID1 is highlighted.

When the reverse display of ID1 is completed, step 1
At 09, an ID deletion confirmation screen is displayed. Here, the ID to be deleted (ID1) is displayed. When the "Yes" key is pressed, ID1 is erased by the controller. At this time, a message “deleting” is displayed on the display screen in step 110.

When the ID is deleted, step 11 in FIG.
In step 1, a message of "erased" is displayed for 2 seconds. Here, the left address key is blank, since ID1 has been deleted. In step 112, a remote control ID confirmation / deletion screen is displayed. continue,
Since the second ID1 is to be erased, the address key on which it is displayed is pressed.

In step 113, the pressed address key is highlighted. After the address key is highlighted for a certain period of time, the process proceeds to step 114. Here, the ID (ID1) stored in the pressed address key is displayed to prompt confirmation of deletion. Here, when the "Yes" key is pressed, it is determined that all of the transmitted ID1 of the remote controller 2 has been deleted from the memory, and the process returns to step 103 to display a remote controller ID setting change selection screen. In this case, if the user wants to cancel the operation, the user presses the “No” key and returns to step 112.

Next, registration of an ID will be described. On the remote control ID setting change selection screen in step 103,
When “remote controller ID registration” is selected, step 115
Proceed to. In step 115, the mode shifts to the remote control ID registration mode. Thus, the ID of the remote controller 2 is stored in the memory 46.
Can be stored and registered at any address. If there is only one ID already registered in the memory 46, the process proceeds to step 118; otherwise, the process proceeds to step 116.

In step 116, a remote control ID registration screen is displayed. At this time, the address key whose ID is already registered is highlighted. In the embodiment, the IDs are already registered in the memory 1 and the memory 2 and their address keys are highlighted. Step 1 when a number whose ID is already registered among the address keys is operated

When the "Yes" key is operated, the process proceeds to step 119 to rewrite the registration ID with a new ID,
When the "No" key is operated, the process returns to step 116. If an address key for which an ID is not registered is operated, the process proceeds to step 119 to store and register a new ID at an unused memory address.

On the other hand, if there is only one ID already registered, a screen for prompting the user to select an address for newly registering an ID is displayed in step 118. At this time, even if the address key whose ID has been registered is operated, it is not accepted. When an unused address key is operated, the process proceeds to step 119 to store and register a new ID at that memory address.

In step 119, a message prompting operation of the remote controller 2 for newly registering an ID is displayed.
Then, it receives the ID transmitted from remote controller 2 and stores the received ID in the memory address specified in step 116 or step 118. In the following step 120,
The remote control ID registration completion message is displayed. At this time, the address key whose ID has been registered is highlighted. Then, when the "end" key is operated, the flow returns to step 103 to display a remote control ID setting change selection screen. Also,
When the "register next" key is operated, the process proceeds to step 116, and another ID is registered in the above-described procedure.
