Abstract
A rear-view mirror system for a motor vehicle comprises a mirror housing, a reflective member mounted in the housing, electrically operated drive means for varying the orientation of the reflective member, a position sensor for producing a signal indicating the actual position of the reflective member, and a data processor comprising means for storing a value indicating a pre-selected orientation for the reflective member and means for comparing said value with the signal from the position sensor and producing a control signal for the drive means. The data processor includes a decoder and is located in the housing and is connected to an encoder at a central location, the encoder being arranged to send a multiplicity of data signals to the processor on a common data transmission line.
