Abstract

A device for controlling an electrically-operated holding magnet of a parking lock of a motor vehicle transmission in which a holding magnet supplied with power via a transmission control resettable to a basic setting holds the parking lock in the disengaged state, an apparatus for bridging a reset of the transmission control that maintains the power supply of the holding magnet during the reset being provided.
