Field of the Invention The present invention relates to a speed regulating device of an automobile windshield wiper, and in particular, detects the amount of rainwater flowing down the vehicle side trim by a predetermined method, and the predetermined amount corresponding to the detected amount of rainwater. Due to the control signal of the rainfall detection unit 10 for detecting the rainfall received by the vehicle; A wiper drive motor controller 30 which operates a wiper drive motor by receiving a predetermined control signal and controls the operation speed thereof; It is connected between the control signal output terminal of the rainfall detection unit 10 and the wiper drive motor control unit 30, the data about the rainfall applied from the rainfall detection unit 10, the data pre-input to the memory (MEMORY) by the user Comparing the table (DATA TABLE) to calculate the drive speed of the wiper, and includes a microcomputer 20 for applying a control signal for the speed of the wiper drive motor to the control signal input terminal of the wiper drive motor control unit 30. Automatically adjusting the speed of the windshield wiper for automobiles, characterized in that it is configured to continuously detect whether the rain is raining, if the rain is detected by using the rainfall detector 10, the value corresponding to the rainfall as a voltage value Sensor value detection step (100); By comparing the voltage value of the rainfall detected by performing the sensor value detection step 100 with the data table of the rainfall and the voltage already input to the microcomputer 20, the current rainfall is detected by the vehicle to detect the wiper A wiper driving speed determining step 200 for determining a driving speed; After performing the wiper driving speed determining step 200, by operating the wiper driving motor (M), the wiper driving step of operating the wiper at the drive speed of the wiper determined by performing the wiper driving speed determining step (200) It is a control method of the automatic speed regulating device of the vehicle windshield wiper, characterized in that configured to include 300.
