Method for operating electromagnetic actuation unit, particularly electromagnetic operating valve, for example fuel injection valve or brake valve, involves determining current stroke of valve element in consideration of size

摘要

The method involves determining a current stroke of a valve element (20) in consideration of a size, which characterizes a current inductance. The size is determined in consideration of an increase of flowing current or corresponding value by a coil (14) of an electromagnetic actuation unit (12). Independent claims are included for the following: (1) a computer program for the execution of the method; and (2) an electrical storage medium for a controlling and regulating unit of an internal-combustion engine.
