Abstract

A circuit and a process are used to control operation of an electromagnetic drive arrangement for power window lifters, sun roofs, or door locks of a motor vehicle. After recognition of a failure of functions or parts thereof or electrical or electronic components, emergency operation is initiated. The operation of electromagnetic drive arrangement is enabled by a switching element, and the control level for the control of the switching element is verified by the running of a safety routine before possible emergency operation.
