`ABSTRACT
`
`A method for the electronic monitoring and control of the
`opening and closing operation of electrically operated
`aggregates, particularly of Window lifters and sunroofs in
`motor Vehicles, is described. Aregulating unit of the aggre-
`gate is connected to a vehicle electrical system. The regu-
`lating unit is directly influenceable Via electrical operating
`control elements, i.e., Via a control-electronics interfacing
`circuitry connected to the aggregate. The control electronics
`interfacing circuitry is supplied with a signal
`that
`is a
`function of an accelerative force acting on a motor-Vehicle
`body.
`
`The signal which is a function of the accelerative force, is
`determined from a motor speed of the regulating unit.
