Vehicle door control system
First Claim
1. A vehicle door control system comprising:
- a portable device for receiving a request signal and transmitting a response signal including an ID code thereof in response to the request signal; and
a vehicle unit mounted in a vehicle for transmitting the request signal, receiving the response signal from the portable device through intercommunications, checking the ID code included in the response signal and controlling conditions of vehicle doors according to a check result of the ID code, wherein the vehicle unit includes a lock condition control unit that controls lock and unlock conditions of the vehicle doors;
an automatic opening/closing unit that automatically opens and closes the vehicle doors;
an inferring means that infers whether a holder of the portable device is going to ride in the vehicle; and
a riding-time control means that unlocks the vehicle doors by the lock condition control unit and automatically opens the vehicle doors by the automatic opening/closing unit when the check result of the ID code included in the response signal responding to the request signal transmitted to an exterior of the vehicle with the vehicle doors locked is determined as OK, and it is inferred by the inferring means that the holder of the portable device is going to ride in the vehicle.

Abstract
A vehicle door control system provides increased usability convenience to users by a function for automatically opening and closing vehicle doors. When a response signal has been continuously received over a predetermined period from a portable device in response to a request signal periodically transmitted from a vehicle unit, it can be inferred that the holder of the portable device has not merely passed by the vehicle but stays in the vicinity of the vehicle with the will to ride in the vehicle. Therefore, vehicle doors having the automatic opening/closing function are unlocked and automatically opened. This eliminates a need for the holder of the portable device to command the operations of unlocking and automatically opening the vehicle doors.
