Motion control device of car rearview mirror operating according to driver's eyes and method

摘要

The motion control device of a car rearview mirror that operates according to the driver's line of sight so that the position of the rearview mirror can be automatically changed according to the driver's line of sight that changes when the left / right rearview mirror is used without a separate operation switch. And a start switch for changing the state according to an operation state of the ignition key of the vehicle to provide the method. An eye camera which detects the driver's gaze and converts it into an electrical signal and outputs the converted electric signal; Gaze coordinate detection means for calculating a coordinate position of the driver's gaze by using the signal input from the eye camera and outputting the electric signal as an electric signal; When the start operation is completed by the operation of the start switch by the driver, connected to the start switch and the eye coordinate detecting means, the position of the left / right rearview mirror is determined and stored in the memory device, and then the front eye position of the driver is determined. Set the reference position and gaze range, and if the determined driver's gaze position is within the set gaze range, calculate the gaze displacement using the reference position, and then determine the position of the rearview mirror mounted in the corresponding direction. Operation control means for calculating an operation degree of the rearview mirror and outputting a control signal capable of varying the position of the rearview mirror to the corresponding position; It is connected to the operation control means, it consists of a motor driving means for moving the position of the left or right rearview mirror in the left / right or up / down direction according to the applied control signal.
