Title: Drive device and method for moving a vehicle part
IPC: H02H1/04
Filed: 1999-09-03
Abstract: A process for displacing a motor vehicle part between at least two positions and a drive device for executing this process in which the motor vehicle part is driven by an electric motor (10), a pulse signal is generated according to the rotary motion of the electric motor (10) and is supplied to a control unit (24) for controlling the electric motor (10), and the instant of input of each signal on the control unit (24) is acquired. Furthermore, at certain instants, a respective for the change of motor rpm is determined from at least some of these previously measured instants, from each value of the rpm change a force change value (DELTAF*[k]) is computed and at least some of the previously determined values of the force change are added up with weighting in order to determine the value for the instantaneous force acting on the moveable motor vehicle part. This value is used as the criterion in deciding whether or not the electric motor (10) is turned off or reversed. In the computation of the values of the force change, for each value of the rpm change which exceeds an upper threshold, the value of this upper threshold is used instead of the value of the rpm change.
