Abstract:
Method for control of a proportional magnet comprising a magnet core, a magnet armature, a magnet coil for operating a control element in a shift valve or a proportional pressure-control valve, particularly a pressure-control valve for clutch operation in an automatic motor vehicle transmission, and comprising an electronic control device, whereby the magnet core may be moved back and forth between a control region and a hold region with a magnetic hold position of the magnet armature and a defined transition from the control region to the hold position may be executed and whereby mechanisms are provided for recognition of the movements of the magnet armature.
