Abstract

A driving device of opening and closing member for automatically controlling the opening and closing member includes a driving means including a driving motor that drives an opening and closing member to open or close, and a clutch, a position detecting means for detecting a relative position of the opening and closing member, and a drive controlling means for controlling an operation of the driving means by using an output information from the position detecting means. When the drive controlling means is reset, the clutch is brought in a disengagement state, and the drive controlling means specifies a present position of the opening and closing member by using an output information from the position detecting means after the reset of the drive controlling means so as to control a subsequent automatic opening and closing operation of the opening and closing member.

Claims

1. A driving device of opening and closing member for automatically controlling the opening and closing member comprising:

a driving means including a driving motor that drives an opening and closing member to open or close, and a clutch disposed between the driving motor and the opening and closing member;

a position detecting means for detecting a [relative] position of the opening and closing member;

a drive controlling means for controlling an operation of the driving means by using an output information from the position detecting means;

wherein when the drive controlling means is reset, the clutch is brought in a disengagement state, and the drive controlling means specifies a present position of the opening and closing member by using an output information from the position detecting means after the reset of the drive controlling means so as to control a subsequent automatic opening and closing operation of the opening and closing member.

2. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 1, wherein the drive controlling means uses a position information, which is obtained from the position detecting means, indicating a position of the opening and closing member before the reset of the drive controlling means, in addition to the output information.

3. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 1, wherein the output information is a moving information indicating whether the opening and closing member has moved after the reset of the drive controlling means.

4. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 1, wherein the output information is a displacement information indicating an amount of movement of the opening and closing member after the reset of the drive controlling means.

5. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 1, wherein when the present position of the opening and closing member is specified to be in the vicinity of either end portion of a driving area of the opening and closing member, the drive controlling means sets an end portion specifying value as a position information of the opening and closing member.

6. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 5, wherein when a present position of the opening and closing member is specified to be in the vicinity of a fully open position of the opening and closing member, the drive controlling means sets a fully open learning value as the end portion specifying value.

7. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 1, wherein the drive controlling means measures a moving amount of the opening and closing member after the clutch is brought in a disengagement state, and determines whether the opening and closing member is stopped after moving.

8. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 2, wherein the drive controlling means determines whether the opening and closing member is positioned in the vicinity of either end portion of a driving area based on position information of the opening and closing member before and after the reset of the drive controlling means.

9. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 1, wherein the drive controlling means sets an end portion specifying value based on whether the opening and closing member is in the vicinity of a fully open position.

10. A driving device of opening and closing member for automatically controlling the opening and closing member according to claim 1, wherein the opening and closing member is a back door for a vehicle.
