Abstract

A system of a side mirror of a vehicle includes: 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 selecting unfolding or folding of the side mirror; an electric power source supplying electric power to the driving motor; and 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 of reversing a rotation direction of the side mirror.

Claims

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 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 the completion of the folding operation and the unfolding operation of the side mirror.

2. The driving system of claim 1, wherein the mirror driving unit comprises:

a controller receiving a selected signal of the switch and generating a signal according to the input signal;

a relay driving circuit receiving the signal of the controller and supplying a relay driving signal;

a relay which is switched according to the signal applied to 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.

3. The driving system of claim 1, wherein the mirror driving unit is installed in a side door of a driver seat.

4. The driving system of claim 1, wherein the detecting means is a rotating angle sensor provided for sensing a rotating angle of the driving motor to detect a completion of the folding and unfolding of the side mirror.

5. The driving system of claim 1, wherein the detecting means is position sensors provided at a folding completion position and an unfolding completion position, respectively, for detecting completions of the folding and unfolding of the side mirror.
