Abstract
The present invention relates to the control of a window washer system associated with a system for wiping a glazed surface of a motor vehicle, said wiper system comprising a wiper motor for rotating at least one wiper blade holder arm, and this window washer system comprising a liquid reservoir connected to at least one nozzle designed to deliver, over a wiping cycle, at least one liquid jet for at least a first window washer system activation period defined between an instant (t) for initiating the spraying of the liquid and an instant (t) for stopping the spraying of the liquid, these instants each being determined as a function respectively of a first angular position and of a second angular position of the wiper blade holder arm defining a first angular sector in which the spraying of the liquid is continuous. According to the invention, the instant (t) for initiating the spraying is advanced by a compensation period (t) corresponding at least to the period for feeding the liquid from the reservoir to the nozzle.
