发明名称 Method of detecting overload state of on-vehicle electric motor and apparatus thereof
摘要 A method of controlling an on-vehicle electric opening/closing body includes the steps of detecting an increased amount of driving current of a motor at a predetermined time interval, comparing the increased amount of the driving current, the number of times of continuous increases in driving current, or an accumulated value of the increased amount of the driving current with a predetermined threshold to perform decision of over load, and varying the threshold according to voltage applied to the motor, rotation directions of the motor, or a type of object generating the over load. It is thereby possible to surely detect the over load which is accidentally generated when sliding a sun-roof, a power window, or the like.
