Abstract
A windshield window wiping system, including a wiper blade in contact with a windshield window; a wiper motor operatively connected to the wiper blade, configured to perform a wiper blade stroke; a reservoir for a wash fluid; a first plurality of holes on a first leading edge of the wiper blade, configured to project the wash fluid toward the windshield window; a wash pump, wherein the wash pump is hydraulically connected to the first plurality of holes; and a first electronic circuit, configured to estimate a position of the wiper blade during the wiper blade stroke based on an input to the first electronic circuit and to synchronize the projection of the wash fluid toward the windshield window with the estimated position of the wiper blade. In other aspects, a method of wiping a windshield window and a non-transitory computer readable medium are provided.
