Outside rearview mirror flexing mechanism and control method thereof

A control method of an outside rearview mirror flexing mechanism for a vehicle, capable of moving said outside rearview mirror between a flexed position and an extended position and vice versa, of the type comprising an electric motor, a mechanical transmission, an electronic control circuit and a position detector informing on the position of the flexing mechanism, where said flexing mechanism is capable of attaining an activated state by being connected to an electrical power source and said rearview mirror is being moved from said flexed position to said extended position or vice versa, said flexing mechanism including a locking mechanism with indents and protrusions distributed between a fixed and a movable part of the rearview mirror which mesh together but can disengage in the presence of a strong force on said movable part, so that said flexing mechanism is capable of being in a locked position and in a disengaged position, characterized in that said electronic control circuit performs a reading of an output signal of said position detector informing on the position of the flexing mechanism and when in said disengaged position, said electronic circuit activates that electric motor so that the mechanism itself corrects this position, automatically adopting a locked position again, and characterized in the said electric motor and said position detector are supplied by common electric wires and in that through one of said supplying electrical wires is obtained said reading of the position detector output signal.
