ABSTRACT:
A rearview mirror assembly is provided for a vehicle which incorporates a self-contained magnetic field sensor in the mirror housing. When mounted to a fixed pivot point in a single ball mounting bracket, the mirror housing pivots around the magnetic field sensor. When the magnetic field sensor is mounted within the mirror housing either to the housing or to the mirror, compensation for the rotation position of the mirror about a vertical axis is provided by an empirically predetermined compensation value whereby direct reading of the angle is adjusted by a processor or by mechanically mounting the field sensor at an angle representative of the compensation value. Other ways of rotation compensation are also disclosed. Compensation for tilt about a horizontal axis is provided by an elliptical compensation algorithm in a microprocessor.
