Prevention apparatus and method of vehicle wiper-driving motor disorder
[10] The present invention relates to a wiper motor failure prevention apparatus and method of the vehicle. More particularly, when the wiper motor operating switch is "on" and detects the drive current of the wiper motor and flows more than a predetermined current (i.e., overload) ) It was invented to recognize that the icing occurred between the wiper blade and the front glass and to drive the thawing heater installed in the front glass or the wiper blade to prevent the wiper motor from failing due to overload.
[11] In general, a wiper is a general term for wiping snow, rain, or muddy water on a rear window, side window, side mirror, headlamp, etc., starting with a windshield of a vehicle.
[12] On the other hand, when the front glass is frozen in winter, the wiper blade is also kept fixed by the ice frozen on the front glass surface. However, in the case of the conventional car, the wiper operation is blocked when the front glass and the wiper blade are frozen together. There were no obstacles to make or thaw the ice.
[13] Therefore, if the driver or the like does not recognize the front glass and the wiper braid as mutually frozen as described above, the wiper motor may cause excessive current flow (ie, an overload) in the wiper motor. The situation is working.
[14] The present invention has been made to solve such a conventional problem, and when the drive current of the wiper motor flows more than a predetermined current, the state between the wiper blade and the front glass is frozen, so it is recognized as an overload condition and the front glass or wiper It is an object of the present invention to provide a wiper motor failure preventing device and a method of a vehicle which can prevent the wiper motor from failing due to overload by driving a heater installed in the blade.
[15] The object of the present invention described above, when the wiper motor is operated when the manual wiper motor operation switch is "on" or the rain sensor is "on", the drive current and the number of revolutions of the motor is detected and the current flows over a predetermined current. If it is less than the rotation speed it can be achieved by recognizing that the gap between the wiper blade and the front glass is frozen and driving the thawing heater installed in the front glass or the wiper blade.
[16] Therefore, the wiper motor can be prevented from failing due to overload due to freezing occurring between the wiper blade and the front glass.

[17] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[18] 1 shows a block diagram of the apparatus of the present invention, FIG. 2 shows a flowchart for explaining the method of the present invention, and FIG. 3 shows a perspective view of an automobile front glass in which the present invention is implemented.
[19] According to the present invention, the wiper motor 3 is operated when the manual wiper motor operation switch 1 selectively operated by a driver or the like is turned on or when the rain sensor 2 is turned on when the rain falls. In the wiper operating system of the front glass 7 configured to operate,
[20] The motor current and rotation speed detecting unit detects the driving current and the rotation speed of the wiper motor 3 and generates a driving signal to the relay 5 when the driving current flows above the set current or the rotation speed is below the set rotation speed ( 4) and;
[21] A relay (5) which is turned on / off in response to the output signal of the motor current and the rotational speed detection unit (4) to control the voltage supplied to the heater (6);
[22] The motor current and rotation speed detection unit 4 drives the relay 5, and when the power supply voltage is supplied, it is characterized in that the additional installation of the thawing heater (6) to thaw the freezing state by operating the heat.
[23] At this time, the thawing heater 6 may be installed in the transverse direction at the bottom of the front glass 7 or may be installed in the wiper blade 8 itself.
[24] The method also includes detecting whether the manual wiper motor actuation switch 1 is "on" by a driver or the like;
[25] Detecting whether the rain sensor 2 is "on" due to rain;
[26] Operating the wiper motor (3) when any one of the wiper motor operation switch (1) and the rain sensor (2) is "on";
[27] Detecting driving current and rotational speed of the wiper motor 3 through a motor current and rotational speed detector 4 when the wiper motor 3 is operated as described above;
[28] If the motor current and the rotation speed detection unit 4 detects that the driving current of the motor flows more than the set current or the rotation speed is less than the set speed, the front glass 7 or the wiper blade 8 through the relay (5). Operating a thawing heater (6) installed in the); characterized in that consisting of.
[29] Referring to the effect of the present invention made of such a configuration and steps as follows.
[30] First, when the fine wiper sensor 2 is automatically “on” because the manual wiper motor operation switch 1 is “on” or the rain falls due to a driver or the like, the output voltage of the battery 9 becomes the wiper motor 3. Is supplied to the motor to operate.
[31] At this time, the motor current and the rotation speed detection unit 4 installed in the wiper motor 3 continue to detect the drive current and the rotation speed of the wiper motor 3 to compare the set current with the set rotation speed.
[32] As a result, if the drive current of the wiper motor 3 flows more than the set current, or if the rotation speed is less than the set rotation speed, icing occurs between the front glass 7 and the wiper Freid 8, and the wiper motor 3 Recognizing that the state is overloaded, the relay 5 is driven to supply a power voltage to the thawing heater 6 embedded in the bottom of the front glass 7 or the wiper blade 8 itself so as to generate heat. .
[33] Therefore, since the thawing heater 6 automatically thaws the frost generated between the front glass 7 and the wiper fred 8, the factor that causes the wiper motor 3 to be overloaded is automatically solved. Can be prevented from failing due to overload.
[34] Of course, the motor current and the rotation speed detection unit 4 continue to detect the drive current and the rotation speed of the wiper motor 3 and set the drive current while the above and steel thawing heater 6 generates heat. When the current flows below the current or the rotation speed is higher than the set rotation speed, it is recognized that the frost between the front glass 7 and the wiper fred 8 is completely thawed, and the driving of the relay 5 is interrupted to cut the driving of the relay 5. Since it automatically cuts off the power supply voltage to), side effects due to overheating of the thawing heater 6 are prevented.
[35] As described above, according to the present invention, if the wiper motor operation switch is "on" or the rain sensor is "on" and the wiper motor is operated, the drive current and the rotational speed of the motor are continuously detected and a predetermined current or more flows. If the rotation speed is lower than the set speed, the wiper blade and the front glass are recognized as frosted, and the windshield heater or the thawing heater installed in the wiper blade is driven so that the wiper motor is caused by the icing between the wiper blade and the front glass. It is possible to prevent the failure due to overload, which can greatly prolong its life.
