Abstract

A drive control apparatus includes an opening-and-closing body. A first driver drives the opening-and-closing body in a closing direction. A second driver moves the opening-and-closing body from a half-latched position to a fully-latched position. A fully-latched detector detects that the opening-and-closing body has reached the fully-latched position. A stop detector detects whether a predetermined stopping condition has been satisfied for stopping the driving of the opening-and-closing body in the closing direction. A drive controller is configured to drive the opening-and-closing body via the first driver in the closing direction. Upon the fully-latched detector detecting that the opening-and-closing body has reached the fully-latched position, the second driver ends operation and the first driver continues to drive the opening-and-closing body in the closing direction until the stop detector detects that the predetermined stopping condition is satisfied.

First claim

The invention claimed is:

1. A drive control apparatus comprising:
an opening-and-closing body for opening and closing an opening;
a first driver configured to drive said opening-and-closing body in a closing direction from an arbitrary opened position;
a second driver configured to drive said opening-and-closing body from a half-latched position to a fully-latched position;
a fully-latched detector configured to detect that said opening-and-closing body has reached said fully-latched position as said opening-and-closing body is being closed;
a stop detector configured to detect whether a predetermined stopping condition has been satisfied for stopping a driving of said opening-and-closing body in the closing direction via said first driver; and
when said fully-latched detector detects that said opening-and-closing body has reached the fully-latched position, a drive controller is configured to drive said opening-and-closing body via said first driver in the closing direction until the stop detector detects that the predetermined stopping condition is satisfied such that the opening-and-closing body is held in a fully-closed position until the drive controller receives an instruction to open said opening-and-closing body, wherein the predetermined stopping condition includes at least one of
a predetermined period of time lapsing after said opening-and-closing body is detected reaching the fully-latched position, and
pulse signals indicating rotation of a motor of said first driver are not detected.

2. The drive control apparatus according to claim 1 , further comprising a half-latched detector configured to detect that said opening-and-closing body has reached said half-latched position when said opening-and-closing body is being closed,
wherein said drive controller is configured to drive, via said first driver, said opening-and-closing body in the closing direction from the arbitrary opened position to said half-latched position;
upon said half-latched detector detecting that said opening-and-closing body has reached said half-latched position, said second driver moves said opening-and-closing body from said half-latched position to said fully-latched position and said first driver continues to drive said opening-and-closing body in the closing direction;
upon said fully-latched detector detecting that said opening-and-closing body has reached said fully-latched position, said second driver ends said moving in of said opening-and-closing body, and said first driver continues to drive said opening-and-closing body in said closing direction until said stop detector detects that the predetermined stopping condition is satisfied.

3. The drive control apparatus according to claim 1 , wherein, when said fully-latched detector detects that said opening-and-closing body has reached said fully-latched position and the driving of said opening-and-closing body in said closing direction by said first driver and the driving of said opening-and-closing body by said second driver have stopped, said drive controller thereafter commences the driving of said opening-and-closing body in said closing direction via said first driver, and said first driver drives said opening-and-closing body in the closing direction until said stop detector detects that said predetermined stopping condition is satisfied.

4. The drive control apparatus according to claim 1 , further comprising a half-latched detector configured to detect that said opening-and-closing body has reached said half-latched position when said opening-and-closing body is being closed,
wherein, when said half-latched detector detects that said opening-and-closing body has reached said half-latched position and the driving of said opening-and-closing body in said closing direction by said first driver and the driving of said opening-and-closing body by said second driver have stopped, said drive controller commences the driving of said opening-and-closing body via said second driver so that said opening-and-closing body moves from said half-latched position to said fully-latched position; and
when said fully-latched detector detects that said opening-and-closing body has reached said fully-latched position, said drive controller ends the driving of said opening-and-closing body by said second driver and commences the driving of said opening-and-closing body in the closing direction via said first driver such that said first driver drives said opening-and-closing body in said closing direction until said stop detector detects that the predetermined stopping condition is satisfied.

5. The drive control apparatus according to claim 1 , further comprising a half-latched detector configured to detect that said opening-and-closing body has reached said half-latched position when said opening-and-closing body is being closed,
wherein, when the half-latched detector detects that said opening-and-closing body has reached said half-latched position and the driving of said opening-and-closing body in said closing direction by said first driver and the driving of said opening-and-closing body by said second driver have stopped, said drive controller simultaneously commences the driving of said opening-and-closing body in said closing direction by said first driver and the driving of said opening-and-closing body by said second driver so that said opening-and-closing body moves from said half-latched position to said fully-latched position; and
when said fully-latched detector detects that said opening-and-closing body has reached said fully-latched position, said drive controller ends the driving of said opening-and-closing body via said second driver and continues to drive said opening-and-closing body in said closing direction by said first driver until said stop detector detects that said predetermined stopping condition is satisfied.
