Patent ID: 8444189

Claim:
A door closing system for a vehicle for fully closing a door, comprising: a plurality of door open/close devices mounted on a door or a body of the vehicle, each of said door open /close devices having a latch mechanism for engaging with an engaging member mounted on the door or the body so as to be in a half-latch state or a full-latch state; a motor for driving the latch mechanism; a latch state detecting member for detecting if the latch mechanism is in a half-latch state or a full-latch state; and a control member including programmed instructions in a computer for automatically starting to: drive synchronously all the motors of the door open/close devices to change the latch mechanisms from the half-latch state to the full-latch state only when in a first condition that all the latch state detecting members of the door open/close devices detect that the latch mechanisms are in the half-latch state in a case that the door of the vehicle is changed from a fully opened state to a fully closed state, and corresponding to this detection, drive the motor of any one of all the plurality of door open/close devices when in a second condition that the latch state detecting member of any one door open/close device, but not all the plurality of latch state detecting members of the door open/close devices, detects that the latch mechanism is in the half-latch state, and drive synchronously the motors of all the door open/close devices except the any one door open/close device to change all the latch mechanisms from the half-latch state to the full-latch state when, during the second condition, the latch state detecting members of all the door open/close devices detect that the latch mechanisms are in the half-latch state in a case that the door of the vehicle is changed from a fully opened state to a fully closed state.
