Abstract
An auto-adjusting electric rear-view mirror includes at least two driving mechanisms for driving the rear-view mirror to deflect. The driving mechanisms are respectively coupled to servo control circuits that are further connected to sensor members. The servo control circuits are also coupled to a master control circuit that is further connected to an external controller. The sensor members can sense a positional variation of the rear-view mirror and send a feedback signal to the servo control circuits. The servo control circuits compare a signal from input ports thereof with the feedback signal, and output a control signal to the driving mechanisms according to the comparison result to drive position or negative rotation of the driving mechanisms, such that the rear-view mirror would automatically adjust its view angle to ensure driving safety.
