1. A remote control system for controlling accessibility of an automobile comprising:
- at least one door lock;
a transmitter in each of at least two doors on the automobile for transmitting a request signal;
a portable device for transmitting a response signal having an identification code in a response to the request signal;
a receiver for receiving the response signal; and
a controller for controlling the door lock based on a comparison of the identification code with a registered code, wherein each transmitter transmits the request signal in a specific interval that reflects a usage of each door.

2. A remote control system for controlling accessibility of an automobile comprising:
-
at least one door lock;
a transmitter in each of at least two doors on the automobile for transmitting a request signal;
a portable device for transmitting a response signal having an identification code in a response to the request signal;
a receiver for receiving the response signal; and
a controller for controlling the door lock based on a comparison of the identification code with a registered code, wherein the controller identifies the transmitter that transmitted the request signal based on the response signal received by the receiver, the controller records information on the identified transmitter as a history of use, and the controller controls the transmitter in less frequent use to transmit the request signal less frequently based on the history of use. - View Dependent Claims (3, 4)

6. A remote control system for controlling access to an automobile comprising;
-
at least one door lock;
a station unit configured for mounting in the automobile to control the door lock;
a portable device for transmitting a first signal in a response to a user operation and a second signal in a response to a request signal;
the station unit having;
a transmitter for intermittently transmitting the request signal to the portable device;
a receiver for receiving the first signal and the second signal from the portable device; and
a controller for controlling the door lock, wherein the receiver intermittently operates in a first interval for receiving the first signal, the receiver operates in synchronization with transmission operation of the request signal for receiving the second signal, the controller records use of the first signal and the second signal as a history of use, and the controller controls the transmitter and/or the receiver so that one of reception operation by the receiver for receiving the first signal and reception operation by the receiver in synchronization with transmission operation of the request signal by the transmitter for receiving the second signal is performed less frequently than the other based on the history of use of the first signal and the second signal. - View Dependent Claims (7)

9. A method of remotely controlling an automobile door lock system using a request signal transmitted from a transmitter disposed in each of a plurality of doors and a response signal transmitted in response to the request signal from a portable device, comprising a steps of:
-
providing at least one door lock in the door;
using a receiver on the automobile for receiving the response signal;
confirming an identification code in the response signal with a registered code in the system;
recording information on use of the transmitter as a history when the receiver receives the response signal; and
controlling less frequently used transmitter to transmit the request signal less frequently based on the history. - View Dependent Claims (10)

11. A method of remotely controlling an automobile door lock system using a request signal transmitted from a transmitter disposed in a door, a response signal transmitted in response to the request signal from a portable device and an operation signal for operating a door lock, comprising a steps of:
-
providing at least one door lock in the door;
using a receiver for receiving the response signal and the operation signal;
recording information on use of the response signal and use of the operation signal as a history when the receiver receives the response signal and the operation signal; and
decreasing frequently of one of operation of the receiver for receiving the response signal in synchronization with transmission of the request signal by the transmitter and operation of the receiver for receiving the operation signal based on the history. - View Dependent Claims (12)
