FIG. 3A is a timing chart of a driving unit having no malfunction preventing unit as a comparative example, and FIG. 3B is a circuit diagram and a timing chart of the malfunction preventing unit of the embodiment of the present invention.

Referring to the circuit diagram of FIG. 3A and the timing chart of the lower stage, an operation signal is inputted from the rising signal input terminal P1 or the falling signal input terminal P2 of the driving unit 100, When the voltage applied to the base of the NPN transistor TR1 connected to the relay input terminal of the relay RY to be driven is at least 0.7 V, which is the forward voltage of the transistor, a current flows from the collector to the emitter, And the input voltage V applied to the voltage input terminal of the relay RY is applied so that the relay RY is driven and the motor M connected to the driving unit 100 is rotated.

However, when the signals of the locking switch LOCK SW, the up-switch SW-A or the down-switch SW-B of the driver's seat power window switch 10 interfere with the external electromagnetic waves or noise, A forward voltage of 0.7 V or more can be applied to the input terminal RY-1 of the relay RY of the driving unit 100. As a result, the relay RY is driven and the motor M connected to the driving unit 100 ) May be caused to rotate.

3B, the malfunction prevention part of the present invention includes a PNP type transistor TR2 at the front end of an NPN type transistor TR1 connected to the input terminal of the relay RY, unlike the comparative example having no malfunction prevention part described above The collector of the PNP transistor TR2 is connected to the base of the NPN transistor TR1 and the voltage dividing circuit composed of the two resistors R1 and R2 is connected to the emitter of the PNP transistor TR2 A pull-up voltage is applied to the base of the PNP type transistor TR2 and the base of the PNP type transistor TR2 to which the pull-up voltage is applied is connected to the rising signal input terminal P1 of the driving part 100, The down switch SW-B of the driver's seat power window switch 10 that sends an operation signal from the driver's seat P2 to the lower switch SW-B of the driver's seat power window switch 10, the locking switch LOCK SW, (SW-C) and the up switch (SW-D) Connecting one side of the slower one of the switch and the other side of these switches has a base voltage of the PNP-type transistor (TR2) connected to the ground (ground) so as to be conductive when the switch short circuits.

In the malfunction prevention part 200 circuit of the present invention configured as described above, the voltage applied to the base of the PNP-type transistor TR2 is equal to the input voltage V applied to the transistor TR2 by the two resistors R1 and R2 And a pull-up voltage is applied to the input voltage V of the PNP-type transistor TR2.

In order to drive the PNP transistor TR2 to the ON state, the malfunction prevention unit 200 of the embodiment of the present invention configured as described above requires that a current flows from the emitter of the PNP type transistor TR2 toward the base, Since the base is applied with the input voltage V as the pull-up voltage, a potential difference between the base and the emitter of the transistor TR2 is formed to be large, so that even when electromagnetic waves are introduced into the signal of the driver's seat power window switch 10 or noise is generated The PNP type transistor can not be driven in the ON state and as a result, the NPN type transistor (TR1) connected to the rear end thereof is not driven and the relay (RY) is also inactivated, so that the voltage due to external electromagnetic waves, noise, The driving unit 100 does not malfunction.

On the other hand, when the switch is short-circuited to raise or lower the window, the base voltage of the transistor TR2 is grounded and falls to 0 V. Therefore, when the PNP transistor TR2 is turned on with the current flowing from the emitter of the PNP transistor TR2 toward the base So that the NPN transistor TR1 connected to the rear end thereof is also driven in the ON state to operate the relay RY to drive the driving unit 100 so that the window is raised or lowered.

That is, when the switch of the driver's seat power switch 10 is turned on, the operation of the driving unit 100 of the present invention as described above causes the base voltage of the PNP type transistor TR2 to drop to OV while the PNP type transistor TR2 And is controlled in an active low signal mode in which the signal is turned on.

[ And the motor M is rotated to raise the window.

Secondly, when the driver operates the down switch SW-B of the driver's seat power window switch to operate the driver's seat power window switch 10 to lower the non-driver's seat window, When the terminal B1 and the other terminal B2 are short-circuited, the power source S held in the malfunction prevention portion 200 is grounded through the down switch SW-B and the malfunction prevention portion 200 is not operated And the power source S is inputted to the falling signal input port P2 of the driving unit 100 so that the driving unit 100 starts to operate and the power source S is supplied to the motor M, Rotate the window in the reverse direction.

Thirdly, in the case of operating the up-switch of the non-driver's seat power window switch 20 to raise the non-driver's seat window, the driver operates the up-switch SW-D of the non- The power source S that has been caught by the malfunction prevention unit 200 under a short-circuited state (normally) is turned off when the one-side terminal D1 and the other terminal D2 are short- The malfunction prevention unit 200 is not operated while the switch SW-D is grounded and the power source S is input to the rising signal input port P1 of the driving unit 100, The power source S is supplied to the motor M to rotate the motor M to raise the window.

Fourth, when the driver operates the down switch SW-C of the non-driver's seat to operate the down switch SW-C when the driver operates the down switch of the non-driver's seat power window switch 20 to lower the non- The power source S in which the locking switch LOCK-SW of the driver's seat power window switch is held in the malfunction prevention portion 200 under the short-circuited state (normal state) is short-circuited when the one terminal C1 and the other terminal C2 of the driver's seat power window switch are short- The malfunction prevention unit 200 is not operated while being grounded through the down switch SW-C and the power source S is inputted to the falling signal input port P2 of the driving unit 100, The power source S is supplied to the motor M to reverse the rotation of the motor M to lower the window.

When the operation of all the windows is to be stopped by operating the locking switch LOCK SW of the driver's seat power window switch 10, normally, the locking switch LOCK- The power source S caught by the malfunction prevention part 200 is released from the down switch SW-C and the up switch SW-D by operating one terminal L1 and the other terminal L2, Of the non-driver's seat power window switch 20 and the operation of the down switch SW-C and the up switch SW-D of the non-driver's seat power window switch 20, The window of the window is not raised or lowered (window locked).

In this state, if the driver operates the locking switch LOCK-SW to short-circuit the locking switch LOCK SW to unlock the non-driver's seat windows by operating the driver's seat power window switch 10 again, The power source S caught by the power source 200 is grounded via the down switch SW-C and the up switch SW-D so that the malfunction prevention part 200 is not operated. In this state, the down switch SW- C and the up switch SW-D, the window on the non-driver's seat side can be raised or lowered.
