THROTTLE POSITION SENSOR

摘要

This invention embodies a single piece magnetic field sensor component part comprising a printed circuit and a Hall Effect IC (Integrated Circuit); the Hall Effect IC comprising two in-built separately programmable Hall Elements. This invention comprises an automobile component comprising above a single piece magnetic field sensor component part; comprising a throttle position sensor. The Hall Effect Sensors generate two independent analog output signals which are proportional to the magnitude of the relative positional change of magnetic flux density and these signals are conveyed to the ECU. One of the signals is a redundant signal This invention also comprises a mechanical means for reducing friction between two parts, at least one of the parts is moving against the other; wherein the mechanical means is not a ball bearing. The mechanical means comprises a friction ring of a wear resistant material.
