Automatic door control system and method
First Claim
1. A door control system in which, by performing mutual communication that a portable device returns a response signal including an ID code in response to a request signal transmitted from a vehicle unit, the vehicle unit receives the response signal from the portable device, and matches the ID code included in the response signal with a predetermined ID code specific to a vehicle, and controls the state of a vehicle door, wherein the vehicle unit comprises:
- an internal communication unit that communicates with the portable device in a vehicle compartment as a communication area;
an automatic open/close device that automatically closes the vehicle door;
a detecting unit that detects a distance between the portable device and the vehicle; and
a main control unit that, with the vehicle door opened, after determining that the portable device has reached out of a predetermined range of a periphery of the vehicle from a detection result by the detecting unit, automatically closes the vehicle door by the automatic open/close device when ID code matching is not confirmed as a result of mutual communication with the portable device by the internal communication unit.

Abstract
A main control ECU of a vehicle unit performs mutual communication with a portable device by external transmitters when respective vehicle doors provided with the automatic open/close function are open. The main control ECU further performs, after ID code matching is confirmed, the mutual communication with the portable device by the external transmitters again after a predetermined time. The main control unit still further performs, when the second matching is not confirmed, mutual communication with the portable device by an internal transmitter. The main control unit automatically closes the vehicle doors when the third matching is not confirmed.

18. A door control method for a door of a compartment by communication with a portable device used to open/close the door, the method comprising:
-
detecting whether a compartment door is open;
performing, when the compartment door is detected as being open, a first ID code matching between an ID code received from the portable device during the communication with the portable device and a predetermined ID, the ID code of the portable device being received from the portable device in response to a request signal transmitted toward an outside of the compartment;
performing, after a confirmation of the first ID code matching indicating that the portable device is present near the door, a second ID code matching between the ID codes;
performing, a third ID code matching between the ID codes, the ID code of the portable device being received from the portable device in response to a request signal transmitted toward an inside of the compartment; and
closing automatically the door in response to a non-confirmation of both the second ID code matching and the third ID code matching indicating that the portable device is absent from the door and absent in the compartment, respectively. - View Dependent Claims (19, 20)
