INTERIOR REARVIEW MIRROR SYSTEM
First Claim
1. An interior rearview mirror system for a vehicle, said interior rearview mirror system comprising:
- an interior rearview mirror assembly;
a casing having a reflective element;
said casing being adjustable relative to a mounting structure that mounts said interior rearview mirror assembly to an interior portion of the vehicle;
a compass sensor disposed within said mirror casing and generating an output signal;
a control determining a directional heading of the vehicle responsive to said output signal of said compass sensor, said control automatically compensating for a deviating magnetic field of the vehicle and generating a signal indicative of the directional heading of the vehicle; and
said control determining that said casing is adjusted by an occupant of the vehicle in response to a change in said output signal of said compass sensor being indicative of an abrupt movement of said casing about said mounting structure by an occupant of the vehicle, said control being operable to enter a rapid compensating mode to compensate for the mirror adjustment in response to said control determining that said casing is adjusted by an occupant of the vehicle.

Abstract
An interior rearview mirror system for a vehicle includes an interior rearview mirror assembly, a casing having a reflective element, a compass sensor and a control. The compass sensor is disposed within the mirror casing and has a first magnetoresponsive sensing element and a second magnetoresponsive sensing element. The control receives a first signal indicative of a magnetic field sensed by the first magnetoresponsive sensing element and a second signal indicative of a magnetic field sensed by the second magnetoresponsive sensing element. The control determines that the casing is adjusted by an occupant of the vehicle in response to a change in the first and second signals being indicative of an abrupt movement of the casing about the mounting structure by an occupant of the vehicle. The control is operable to enter a rapid compensating mode to compensate for the mirror adjustment.
