Abstract

A control apparatus for a closure device includes pinch detector for detecting a foreign body being pinched by an opening/closing member when the variation degree of a movement of the opening/closing member reaches a predetermined threshold value. When this control apparatus for a closure device determines that a vehicle is running, the threshold value is set at a second threshold value, which is reduced in a detection sensitivity of pinch as compared with a first threshold value set when the vehicle is stationary. When the apparatus detects that a load not smaller than a predetermined value is applied by disturbance to the opening/closing member in a closing direction, the threshold value is set at a third threshold value, which is reduced in the detection sensitivity of pinch as compared with the second threshold value.

Claims (11)

1. A control apparatus for a closure device comprising:

a drive means that opens and closes an opening/closing member;

a movement detecting means that detects a movement of the opening/closing member opened and closed by the drive means; and

a pinch detecting means that calculates a variation degree of the movement detected by the movement detecting means and detects a foreign body being pinched by the opening/closing member when the variation degree reaches a predetermined threshold value, characterized by further comprising:

a vehicle speed detecting means that detects a running speed of a vehicle;

a threshold value setting means that sets the threshold value; and

a disturbance detecting means that detects a load larger than a predetermined value and is applied to the opening/closing member in a closing direction on the basis of the variation degree,

wherein the threshold value setting means sets the threshold value at a second threshold value, which is reduced in a detection sensitivity of pinch as compared with a first threshold value set when the vehicle is stationary, when the vehicle speed detecting means determines that the vehicle is running, and sets the threshold value at a third threshold value, which is reduced in the detection sensitivity of pinch as compared with the second threshold value when the disturbance detecting means detects that a load not smaller than a predetermined value is applied to the opening/closing member.

2. The control apparatus for a closure device according to claim 1 , wherein the threshold value setting means sets the threshold value at the third threshold value when the vehicle speed detecting means determines that the vehicle is running and when the disturbance detecting means detects that a load not smaller than the predetermined value is applied to the opening/closing member in an opening direction.

3. The control apparatus for a closure device according to claim 1 , wherein the threshold value setting means sets the threshold value at the third threshold value according to a detection result of the disturbance detecting means.

4. The control apparatus for a closure device according to claim 3 , wherein the threshold value setting means resets the threshold value to the second threshold value after a predetermined time passes.
