Title:
DRIVE DEVICE FOR OPENING/CLOSING BODY
Document Type and Number:
WIPO Patent Application WO/2013/099646
Kind Code:
A1
Abstract:
The purpose of the invention is to obtain a drive device for an opening/closing body that can reliably prevent malfunctions arising from the freezing of an electric contact of a relay switch. A control unit (60) is provided with: a freezing assessment unit (61) that determines that a relay switch (SW1, SW2, SW3) is frozen when the opening/closing body drive motor (27a) does not perform normal driving according to an operation condition for opening or closing the opening/closing body (3) and the temperature of the control unit (60) detected by a temperature detector (80) is at or below a prescribed value; and a freezing removal unit (62) that, when the freezing assessment unit (61) determines that a relay switch (SW1, SW2, SW3) is frozen, puts the device in a state in which drive current is not supplied to the opening/closing body drive motor (27a) and then supplies current intermittently for a prescribed number of times to the relay switch (SW1, SW2, SW3) to remove the freezing of the relay switch (SW1, SW2, SW3).
