METHOD FOR ELECTRONIC SURVEILLANCE AND CONTROL OF THE OPENING AND CLOSING PROCEDURE FOR ELECTRICALLY OPERATED UNITS

摘要

The invention relates to a method for electronic surveillance and control of the opening and closing procedure for electrically operated units, especially window lifters and sliding roofs in motor vehicles. It is possible to act upon an actuating element of said unit, whereby said element is connected to the vehicle electric system, in a direct manner using electrical controls or by interconnecting a controlling electronics system that is linked to said unit. A signal that is dependent upon an acceleration force acting upon the bodywork of the motor vehicle is supplied to the controlling electronics system. The signal (16) which is dependent upon the acceleration force acting upon the bodywork is determined from the motor speed (20) of the electronic actuating element.
