Abstract
A steering angle sensor assembly is for use with a vehicle having a rotatable steering mechanism. The assembly includes a first rotational indexing member operably couplable to the steering mechanism for rotation therewith. The steering mechanism and the first indexing member are each rotatable through a rotational range including a plurality of revolutions. The first indexing member defines a first rotational axis. A plurality of indexing elements are disposed on the first indexing member and circumscribe the first rotational axis. A first sensing device is positioned to sense the plurality of indexing elements as the first indexing member rotates. The first sensing device outputs a first signal representative of a rotational position of the first rotational indexing member within one of the revolutions. A second rotational indexing member defines a second rotational axis. A reduction gear mechanism operably couples the first and second indexing members. A rotational displacement of the second indexing member is less than a corresponding rotational displacement of the first indexing member. A second sensing device senses a rotational position of said second rotational indexing mem…
