REDUNDANT HAZARD MITIGATION METHODS FOR AN ETRS CONTROLS ARCHITECTURE

摘要

A method for retracting an extended pin of a sliding camshaft actuator wherein the actuator includes a magnetic field generating coil, a magnetic piston in connection with the extended pin operable to be actuated by the magnetic field generating coil, and a pin stop plate. The method comprises creating an air gap between the magnetic piston and the pin stop plate and reversing voltage on the magnetic field generating coil to retract the extended pin.
