ABSTRACT:
There is disclosed a control device for use with at least one electrically controlled rearview mirror apparatus, each apparatus having a motor for angularly moving a rearview mirror about at least one axis, and position adjustment means for allowing an operator to adjust an initial position of the mirror, the device being able to move the mirror from the initial position to a blind spot position and to return the mirror substantially to the initial position and comprising: an activating switch for providing a start signal in response to the operator; a timer; switching relays for controlling the motor to move the mirror in a path between the initial and blind spot position; and a controller for controlling a movement cycle of the mirror, the movement cycle being initiated by the start signal, the controller causing the switching relays to move the mirror along the path for a first time period as determined by the timer so as to move the mirror between the initial and blind spot positions, to stop the mirror for a second time period as determined by the timer, and to move the mirror for a third period of time as determined by the timer so as to return the mirror from the blind spot position to the initial position. The device allows for blind spot scanning without adding to the mechanical control system of the side rearview mirror apparatus.
