Patent ID: 6888335

Claim:
An electronic control system for controlling the position of a vehicle door via control of an electric motor mechanically coupled to said vehicle door, said system comprising: a position detector mechanically coupled to said vehicle door for detecting at least one of a position and a velocity of said vehicle door; an abnormality detector electrically coupled to said position detector for detecting a deviation between said at least one of said position and said velocity of said vehicle door and at least one of a commanded position and a commanded velocity of said vehicle door, whereby an abnormal operation of said vehicle door is detected; and a control circuit electrically coupled to said abnormality detector and further electrically coupled to said electric motor for controlling operation of said electric motor and ceasing operation of said electric motor in response to said abnormality detector detecting said abnormal operation, said control circuit including a timer circuit for determining when a predetermined time period after said control circuit ceases operation of said electric motor, and wherein said control circuit resumes operation of said electric motor in response to both an expiration of said predetermined time period and said abnormality detector indicating that said abnormal operation has ceased.
