<p>A device for removing a dead zone of a side view mirror interlocked with a driving signal of a direction indicating lamp is provided to prevent a collision of a vehicle, caused by the dead zone of the side mirror when changing a lane. A device for removing a dead zone of a side view mirror interlocked with a driving signal of a direction indicating lamp comprises upper, lower, left, and right switches(SW1,SW2,SW3,SW4), a signal changing unit(1), a control unit(2), a first driving unit(3), and a second driving unit(4). The upper, lower, left, and right switches control an angle of the side mirror. The signal changing unit changes a light-on signal of the direction indicating lamp into a digital signal. The control unit outputs a control signal to move the side mirror to an outer direction to remove the dead zone of the side mirror for a driver's seat when inputting a predetermined electric signal from the signal changing unit, for pre-set time, and outputs the control signal to return the side mirror to an initial position when the electric signal from the signal changing unit is not inputted, for the set time. The first driving unit rotates a vertical motor normally and inversely according to the control signal of the control unit. The second driving unit includes a transistor(Q3), a relay switch(RL3), the other transistor(Q4), and the other relay switch(RL4). The transistor is turned on and off by the control signal of the control unit. The relay switch supplies normal and reverse driving voltage to a horizontal motor by on and off operations of the transistor. The other transistor is turned on and off by the control signal of the control unit. The other relay switch is switched by the on and off operations of the other transistor to control the voltage supplied to the horizontal motor.</p> |
