Abstract

Invention concerns a method to control power consumption in a windshield wiper unit (1), the windshield wiper unit (1) comprising : - wiper blades (5) configured to wipe the windshield surface ( S ) when set in motion, - at least one motor (7) configured to set the wiper blades (5) in motion, - a controller (9), configured to control the at least one motor (7) according to a plurality of wiping modes ( OFF, INT, HS, LS ), the method comprising the steps : - estimating or measuring the current consumption of the at least one motor (7), - comparing the estimated or measured current consumption (I) value to a predetermined threshold value ( I max , I' max ), - lowering the wiping speed ( W ) of the blades (5) in case the estimated or measured current consumption ( I ) is greater than said threshold value ( I max , I' max ).
