System and method of operating a side mirror of a vehicle
First Claim
Patent Images
1. A driving system of a side mirror of a vehicle, comprising:
- a driving motor which is driven by input electric power and supplies a driving force for rotating the side mirror from a folding position to an unfolding position or rotating the side mirror from the unfolding position to the folding position;
a switch which selects unfolding or folding operation of the side mirror;
an electric power source supplying electric power to the driving motor;
a mirror driving unit supplying electric power to the driving motor from the electric power source according to a signal of the switch, and performing a blocking cancellation operation; and
a detecting means for detecting completions of the folding operation and the unfolding operation of the side mirror;
wherein the detecting means is a rotating angle sensor provided for sensing a rotating angle of the driving motor to detect the completions of the folding and unfolding operations of the side mirror;
wherein the mirror driving unit comprises;
a controller receiving a selected signal of the switch and generating a signal according to an input signal;
a relay driving circuit receiving the signal generated in the controller and supplying a relay driving signal;
a relay which is switched according to the relay driving signal from the relay driving circuit so as to apply electric power of the electric power source to an electric power passage in a forward direction or in a reverse direction; and
a current detector detecting current to the driving motor and supplying a corresponding signal to the controller.
