Pulsed electromagnetic application in vehicle door latch

摘要

Methods and systems for magnetically actuating latch components are disclosed herein. A door latch assembly comprising at least one latching mechanism can be provided for maintaining a door in a locked condition or an unlocked condition. One or more electromagnets can be integrated with the door latch assembly, such that the electromagnet generates one or more pulses in the form of electrical energy that can actuate the latching mechanism from a locked condition to an unlocked condition and vice versa. A pulsed electromagnet is therefore utilized such each pulse of energy applied actuates the latching mechanism a known amount. Such a configuration permits the latching mechanism to be accurately indexed from a known position to another.
