<p>The invention relates to a controller of a wiper system (10) of a motor vehicle, having at least two pumps (27, 28; 33 to 36) for supplying washing liquid (2) to a spraying device, wherein the spraying device has at least one screen wiper (11, 12) assigned to a front screen (1) and having two rows (21, 22) of spray nozzles (23, 24) on both sides along a wiper rubber (16) of the screen wiper (11, 12), wherein each of the two rows (21, 22) of spray nozzles (23, 24) is assigned a pump (27, 28; 33 to 36), and wherein the screen wiper (11, 12) can be pivoted between an upper reverse position (O) and a lower reverse position (U) by means of a screen wiper motor (14, 15). According to the invention, the spray device can be controlled depending on the direction of movement of the screen wiper (11, 12) in such a manner that the supply of washing liquid (2) by the pump (27, 28; 33 to 36) which is assigned to the row (21, 22) of spray nozzles (23, 24) which are trailing in the direction of movement of the screen wiper (11, 12) before the reverse point is reached, is resumed before the reverse point (O, U) of the screen wiper (11, 12) is reached.</p> |
