Abstract
Official abstract text for this publication.
A vehicle system includes a position sensor, a current supply module, and a mode indicator module. The position sensor includes: an electromagnet (EM) that generates a magnetic field proximate to one of an intake valve and an exhaust valve of an engine; and a Hall-effect sensor that generates a position signal indicating a position of the one of the intake valve and the exhaust valve based on the magnetic field. The current supply module supplies current to the EM. The mode indicator module indicates whether the one of the intake valve and the exhaust valve is being actuated in a low lift mode or a high lift mode based on the position signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for a vehicle, comprising: a position sensor that includes: an electromagnet (EM) that generates a magnetic field proximate to one of an intake valve and an exhaust valve of an engine; and a Hall-effect sensor that generates a position signal indicating a position of the one of the intake valve and the exhaust valve based on the magnetic field; a current supply module that supplies current to the EM according to a repeating periodic pattern,…
