ABSTRACT:
An adaptive vehicle power window control apparatus (20) includes an electric motor (28) for moving a member (34) between a first position and a second position. The space between the first position and the second position is divided into a plurality of trap zones and each zone has an associated sensitivity value. A controller 24 determines (40) a value functionally related to the present motor speed and determines (44) a value functionally related to a reference motor speed. The sensitivity value is adjusted as a function of the two determined values. A window zone determining function (62) determines which of the plurality zones the member (34) is located. The value functionally related to present motor speed is adjusted (52) as a function of the sensitivity value for the zone that the member is located. A comparing function (48) compares the adjusted value with the value functionally related to reference motor speed. The motor direction and movement is controlled as a function of the comparison. Zone locations are adjustable with a calibration procedure.
