Document Type and Number:
Japanese Patent JP3339378
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely transmit a code by conversing the code of the equipment and function of a keyless entry object into the remote control signal of a radio wave in an operation state for an operation switch to be transmitted, and specifying a function code in response to the operation state.
SOLUTION: When only the door of a driver's seat is unlocked, an operation switch 12-2 for door unlocking of a transmitter 1 is operated only one time. In the case where the doors of all seats are desired to be unlocked, the operation switch 12-2 for unlocking of the transmitter 1 is operated, for instance, two times within about three seconds. At the time, when two times operation is performed in a short time, code transmission processing corresponding to the one time operation has priority even at the time of being received in execution of the code transmission processing corresponding to the operation of the one time. After the one time transmission processing is completed, the code transmission processing corresponding to the two times operation is surely executed. Thereby remote operation is performed to make operable constitution, and operation instruction for a variety of equipment can be transmitted.
