    Vehicle wiper automatic speed control device and method
    The present invention relates to a vehicle wiper automatic speed control device and a method thereof, in particular, when the operation of the vehicle wiper starts to detect the traveling speed of the vehicle to automatically change the operating speed of the wiper appropriately according to the increase and decrease of the traveling speed. The present invention relates to a vehicle wiper automatic speed control device and a method thereof.
    In general, the wiper for the vehicle cleans the front windshield of the vehicle to prevent the driver's front view from being obscured when driving on a foggy road or in rainy weather.
    The vehicle wiper includes a wiper blade 2 in contact with the front windshield 1 of the vehicle as shown in FIG. 1, and a wiper arm 3 supporting a central portion of the wiper blade 2. It is composed of
    The operation mode of the vehicle wiper configured as described above is generally divided into three modes according to the operating speed: intermittent mode, low speed mode and high speed mode. The intermittent mode is mainly selected when driving a misty road or a road with a small amount of rain, the low speed mode is mainly selected when driving a moderate amount of rainy road, and the high speed mode is a large amount such as a shower. Selected mainly when driving on rainy roads.
    In addition, as shown in FIG. 2, the three operation modes of the vehicle wiper 11 are selected according to the manual operation of the wiper switch 12 mounted at a predetermined position of the driver's seat, and the wiper switch 12 When the operation mode of the vehicle wiper 11 is selected, the wiper operating unit 13 operates the vehicle wiper 11 in the selected operation mode.
    Although not shown in the drawing, the wiper operating part 13 transmits the power of the wiper motor and the wiper motor 3 to the wiper arm 3 shown in FIG. 1 to interlock the wiper blade 2. It consists of a wiper link part.
    That is, the rotation speed of the wiper motor is changed according to the selection of the operation mode of the wiper switch 11, and the operation speed of the vehicle wiper 11 is changed according to the change of the rotation speed of the wiper motor, thereby intermittent mode, low speed mode and high speed mode. Are each implemented.
    On the other hand, even if there is no change in the rain outside the vehicle in the rain, when the driving speed of the vehicle is faster, the driver feels that the rain has increased through the windshield 1 of the vehicle. Therefore, the driver must manually change the operation mode of the vehicle wiper 2 whenever the driver presses the accelerator in rainy weather to increase the traveling speed.
    That is, in the related art, the driver can operate the wiper switch only by manually operating the wiper switch. Therefore, when the operating mode of the vehicle wiper is changed according to the change in the traveling speed of the vehicle, the driver must operate the wiper switch one by one. At the same time, inadvertent driving caused a variety of accidents.
    The present invention has been made to solve the above problems, when the operation of the vehicle wiper starts to detect the running speed of the vehicle by changing the operating speed of the vehicle wiper to a speed proportional to the current driving speed of the driver in the rain It is an object of the present invention to provide a vehicle wiper automatic speed control apparatus and method for achieving convenience and safety of the vehicle.

    Hereinafter, with reference to the accompanying drawings, an embodiment of a vehicle wiper automatic speed control apparatus and method according to the present invention will be described in detail.
    First embodiment
    The vehicle wiper automatic speed control apparatus according to the first embodiment of the present invention is for selecting a stepwise operation mode (intermittent mode, low speed mode, high speed mode) according to the operating speed of the vehicle wiper 51, as shown in FIG. A wiper switch 52, a wiper operating portion 53 for operating the vehicle wiper 51 in an operation mode selected by the wiper switch 51, a speedometer 54 for measuring a traveling speed of the vehicle, and When the operation mode of the vehicle wiper 51 is selected by the wiper switch 52, the driving speed of the current vehicle is read from the speedometer 54 and compared with the speed range preset in the step-by-step operation mode. Accordingly, the wiper control unit 55 is configured to control the wiper operation unit 53 to change the operation mode of the vehicle wiper 51 to a proper operation mode.
    The automatic speed control method using the vehicle wiper automatic speed control apparatus according to the first embodiment of the present invention configured as described above will be described with reference to the flowchart shown in FIG. 4.
    First, when one of the stepwise operation modes (intermittent mode, low speed mode, high speed mode) according to the operating speed of the vehicle wiper 51 is selected by manual operation of the wiper switch 52, the wiper operating unit 53 is the vehicle wiper. Operate 51 in the selected mode of operation, and at the same time the speedometer 54 measures the running speed of the vehicle (first process).
    Thereafter, the wiper controller 55 reads the current vehicle traveling speed from the speedometer 54 and sets the speed range preset in the stepwise operation mode of the vehicle wiper 51 (intermittent mode <Vref1, Vref1≤low speed mode <Vref2, high speed). Mode ≥ Vref2) (second process).
    The wiper controller 55 controls the wiper operating unit 53 when the traveling speed of the vehicle read from the speedometer 54 is greater than the speed range set in the operation mode selected in the first process as a result of the comparison of the second process. Thus, the operation mode of the vehicle wiper 51 is changed to the operation mode of the speed range to which the traveling speed belongs. Here, the operation mode of the vehicle wiper 51 is varied in stages (third process).
    On the other hand, the wiper controller 55 of the vehicle wiper 51 when the running speed of the vehicle read from the speedometer 54 is less than the speed range set in the operation mode selected in the first process as a result of the comparison of the second process The operation mode selected in the first step is set without changing the operation mode.
    For example, while the low speed mode is selected by the wiper switch 52, the running speed of the vehicle is increased so that the operation mode of the vehicle wiper 51 is changed from the low speed mode to the high speed mode, and then the running speed of the vehicle is set to the intermittent mode. Even if the speed range is reduced, the operation mode of the vehicle wiper 51 is changed to a low speed mode rather than an intermittent mode (fourth process).
    As described above, when the wiper controller 55 detects a change in the traveling speed of the vehicle and automatically changes the operation mode of the vehicle wiper 51, the driver needs to manually operate the wiper switch 52 while driving, as in the prior art. It can improve driver's convenience and safety.
    In addition, the first embodiment of the present invention has been described taking the case of three operation modes of the vehicle wiper 51 as an example, and may be applied to the case where more operation modes are set.

The wiper control unit is configured to control the wiper operation unit to increase and decrease the operating speed of the vehicle wiper at a speed proportional to a driving speed of the current vehicle.
    The automatic speed control method using the vehicle wiper automatic speed control apparatus according to the second embodiment of the present invention configured as described above is as follows.
    First, the wiper control unit detects a signal input from the wiper on / off switch to determine whether the vehicle wiper starts to operate (first process).
    In the first process, the wiper control unit controls the wiper operation unit when the on state of the wiper on / off switch is sensed to start the operation of the vehicle wiper, and when the operation of the vehicle wiper starts, the speedometer measures the traveling speed of the vehicle. (Second course).
    Thereafter, the wiper control unit reads the current vehicle's traveling speed from the speedometer, and if the value increases or decreases, the wiper control unit controls the wiper operating unit to change the operating speed of the vehicle wiper to a speed proportional to the read driving speed (third process).
    As described above, in the second embodiment of the present invention, the operating speed of the vehicle wiper is not set step by step as in the first embodiment of the present invention, but is changed analogously according to the change in the traveling speed of the vehicle.
    That is, if the driving speed of the vehicle is increased after the operation of the vehicle wiper is started under the control of the wiper control unit, the operating speed of the vehicle wiper is also increased analogously. If the driving speed of the vehicle is reduced, the operation of the vehicle wiper is accordingly Speed is also reduced analogously.
    Therefore, like the first embodiment of the present invention, the second embodiment of the present invention does not require the driver to manually change the operating speed of the vehicle wiper according to the change in the traveling speed of the vehicle, thereby enhancing the convenience and stability of the driver. have.
    As described above, the present invention detects a change in the traveling speed of the vehicle when the operation of the vehicle wiper starts and automatically changes the operating speed of the vehicle wiper, so that the driver needs to manually change the operating speed of the vehicle wiper while driving. There is no effect that enables the convenience and safety of the driver.
