Abstract:
1. An auto-adjusting electric rear-view mirror, comprising: at least two driving mechanisms for driving a mirror member of the rear-view mirror to turn and change a view angle thereof; a servo control circuit coupled to each of the driving mechanisms and for controlling positive and negative rotation of the corresponding driving mechanism; a sensor member coupled to the servo control circuit and for sensing a positional variation of the mirror member of the rear-view mirror to output a feedback signal to the servo control circuit, so as to allow the servo control circuit to compare the feedback signal with a signal from an input port of the servo control circuit to output a control signal to the corresponding driving mechanism; a master control circuit coupled to the servo control circuit and an external controller, so as to allow the servo control circuit to directly control the corresponding driving mechanism according to a control signal transmitted by the external controller, wherein the external controller is further connected to at least one of a first sensor coupled to a steering wheel axle for sensing a variation of a turning angle of the steering wheel axle and outputting a feedback signal to the external controller and a second sensor coupled to an indicator switch for sensing operating indication of the indicator switch and outputting a feedback signal to the external controller; and a key set coupled to the master control circuit and for inputting a control signal to the master control circuit.
