Abstract

A rearview assembly includes a mount, having a ball joint portion, and a main unit including a housing with a socket that receives the ball joint portion such that the main unit is articulable on the mount by rotation about three perpendicular axes. First and second magnets are positioned within the housing and are spaced apart to define a rotationally asymmetric combined magnetic field. First and second sensors are positioned within the housing are spaced apart so as to be collectively operably associated with the combined magnetic field, with articulation of the main unit on the mount causing movement of the first and second sensors with respect to the first and second magnets. A processor determines a rotational position of the main unit in relation to the mount about the three axes based on a combination of the magnetic field information from the first sensor and second sensors.
