ABSTRACT:
A windshield wiper control apparatus compensates for small-diameter raindrops such as a drizzle and raindrops splashed over by a preceding vehicle which may worsen the visibility of a driver even though the level of precipitation is not much and accumulatively calculates the amount of raindrops just after the wiping action of a wiper blade, thereby causing an optimized automatic wiping action to be realized. In addition, a windshield wiper control apparatus effects an automatic wiper operation without modifications and additional use of new operating switches by only adding a new control device between the conventional windshield apparatus not having any automatic wiper operation and the wiper blade driver.
