Patent ID: 7235944

Claim:
A wiper control system for detecting an amount of raindrops landed on a windshield of a vehicle and driving a wipe operation of a wiper to wipe the landed raindrops, the wiper control system comprising: raindrop sensing means capable of detecting the amount of landed raindrops for each of a plurality of wipe cycles of the wiper; average landed raindrop amount calculation means for calculating an average value of the amount of landed raindrops for the plurality of wipe cycles; vehicle acceleration sensing means for determining an acceleration of the vehicle; wipe operation mode selection means for selecting a wipe operation mode, wherein the wipe operation mode selection means selects the wipe operation mode of the wiper based on the acceleration of the vehicle and one of the amount of landed raindrops and the average amount of landed raindrops; determination means for determining based on the vehicle acceleration whether or not to implement the wipe operation mode selection based on the average amount of landed raindrops, wherein the wipe operation mode selection means selects the wipe operation mode based on the average amount of landed raindrops when it is determined by the determination means that the wipe operation mode selection is implemented based on the average amount of landed raindrops and the wipe operation mode selection means selects the wipe operation mode based on any one of the amount of landed raindrops and the vehicle acceleration when it is not determined that the wipe operation mode selection based on the average amount of landed raindrops is implemented.
