Abstract: The effect of vibration on an obstruction detection system for a vehicle closure member is utilized to eliminate false identifications of an obstruction. The effect of vibration is measured, and utilized to change the expected value or limits relied upon to identify an obstruction. A characteristic such as speed is measured when it moves away from a predicted value in a direction opposed to the direction which would be indicative of an obstruction. In the case of speed, the system measures speed movement above the predicted value. The control senses the absolute value of the movement above the predicted speed value, and utilizes the absolute value to compensate for an expected upcoming valley below the predicted value. This compensation is either utilized to move the predicted value, or a limit, further downwardly. In this way, the expected valley will not move below the limit, which might otherwise result in a false indication of an obstruction.
