Abstract
An intelligent wiper system and method for wiping a windshield is disclosed having a microprocessor which controls the operation of a motor and which is capable of setting a baseline delay time using one or more wipe times, with the baseline delay time generally corresponding to a time interval between consecutive wipes of at least one wiper blade. The system and method automatically adjusts the baseline delay time in response to the second wipe time if the second wipe time is not substantially the same as a function of the first wipe time, wherein the function includes a predetermined constant which is at least one hundred percent of a first wipe time. An upper baseline wipe time threshold and a lower baseline wipe time threshold may be established such that the delay time is not adjusted if a current wipe time falls between such thresholds.
