Title:
OPENING/CLOSING BODY DRIVE CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JP2015124488
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an opening/closing body drive controller for a vehicle capable of improving detection accuracy of pinching.SOLUTION: A DC motor drives and closes a back door having a weather strip interposed between an opening of a body of a vehicle and it. A door ECU calculates an absolute value DN of a rotation speed difference as a deviation between a rotational speed of the DC motor detected in an idle running section and a current rotational speed of the DC motor detected afterward to detect pinching of foreign matter on the basis of the magnitude relation between the absolute value DN of the rotational speed difference and a detection threshold. The door ECU detects duration time in which the back door is opened, and sets a detection threshold TaS when the detected duration time is short to have higher detection sensitivity of catching of foreign matter than a detection threshold TaL when the detected duration time is long.
