To provide a method of detecting the reversing of the sweeping direction, the method implemented for equipping a vehicle with wipers equipped with liquid sprayer devices replacing conventional windscreen wiper blades.SOLUTION: A wiper system for wiping a vehicle window comprises: at least one windscreen wiper blade adapted to be driven by a drive arm of the wiper system with alternating movements sweeping at least one portion of an exterior surface of a window to be wiped between two positions at which the sweeping direction is reversed; a sprayer device for spraying a liquid onto the exterior surface; a feed pump for feeding the sprayer device with the liquid; and a control circuit for controlling the feeding to the sprayer device by the feed pump as a function of the sweeping direction. The system includes an acceleration sensor CA of the windscreen wiper that is carried by the windscreen wiper and that is connected to the control circuit 34 in order to deliver, to the control circuit, signals representing the value of the acceleration of the windscreen wiper.SELECTED DRAWING: Figure 4
