Definitions

  • the invention relates to a controller of a wiper system of a motor vehicle and a wiper system of a motor vehicle according to the preambles of the independent claims.
  • a controller and such a wiper system are known from DE 102 36 886 Al of the applicant.
  • the controller proposed in the cited document is in particular concerned with the economical use of washing liquid, so that a smaller washing agent container can be used if necessary or refilling of the washing agent container during operation of the motor vehicle is only necessary after a relatively long period.
  • a screen wiper can have corresponding rows of nozzle openings on both longitudinal sides, each row of nozzle openings being assigned a separate pump.
  • a bi-pump is proposed, i.e. a pump which has two pump outlets, each row of nozzle openings being connected to one outlet of the pump. It has been found to be disadvantageous during operation of such a wiper system that, when the above-mentioned bi-pump is used, the washing liquid only reaches the nozzle openings of the initially trailing nozzle openings at a time after the reverse point of the screen wiper has been exceeded. This results in annoying changeover noises of the screen wiper as a result of increased friction between the wiper rubber and the screen surface .
  • the invention is based on the object of developing a controller of a wiper system of a motor vehicle and a wiper system of a motor vehicle according to the preambles of the two independent claims in such a manner that the washing liquid is supplied to the nozzle openings of the screen wiper in the region of the two reverse points of the screen wiper in such a manner that there is always enough washing liquid in the movement direction of the screen wiper to reduce the above-mentioned noises and the increased wear of the wiper rubber in the region of the reverse points.
  • This object is achieved in a controller of a wiper system of a motor vehicle and a wiper system of a motor vehicle with the features of the independent claims.
  • the invention is based on the concept of providing the washing liquid in good time to those nozzle openings which are initially situated on the trailing side ahead of a reverse point of the screen wiper in the direction of movement in such a manner that washing liquid exits from the corresponding nozzle openings no later than at the reverse point.
  • the supply of washing liquid by the pump which is assigned to the row of leading spray nozzles before the reverse point is reached be interrupted before the reverse position of the screen wiper is reached. It has been found in practice that, owing to the pressure of the washing liquid prevailing in the hose between the pump and the nozzle openings, a certain amount of washing liquid exits from the nozzle openings even after the pump is switched off, which is in practice sufficient to wet the screen surface as far as the reverse point with enough washing liquid.
  • the controller is designed in such a manner that no more washing liquid exits from the previously leading nozzle openings at the moment when the screen wiper is situated in the reverse position thereof.
  • each of the two screen wipers be assigned two pumps, which are each functionally connected to a row of spray openings, and that the interruption and resumption of the supply of washing liquid to each screen wiper be controlled individually. It is thus possible to control the supply of washing liquid for each screen wiper in a need- and quantity-optimised manner.
  • Reversible screen wiper motors are advantageously used to more the wiper arms and the screen wipers.
  • Such motors are equipped with sensors which detect the respective position of the screen wipers on the screen.
  • the washing liquid can be supplied at the optimal time in a simple manner. Additional sensors for determining the position of the screen wipers can in this case be omitted.
  • the pump in a further advantageous configuration of the invention, it is provided for the pump to be switched on and off in an angle range of the pivot movement of the screen wiper of 5° to 40° before the respective reverse position is reached.
  • Such an angle range ensures that washing liquid exits from the then leading nozzle openings or washing liquid no longer exits from the previously leading nozzle openings no later than at the reverse point.
  • the pumps in order to realise an intensive cleaning programme of the screen surface, for the pumps to be actuated in such a manner that all the pumps supply washing liquid to the nozzle openings to soak the screen surface, in particular during at least a half pivot movement of the screen wiper, such an actuation where appropriate only taking place when the vehicle is stopped.
  • ashing liquid is supplied to the respective nozzle openings through all the pumps.
  • a control device which controls the spray device depending on the movement of the screen wiper in such a manner that the supply of washing liquid through the pump which is assigned to the row of trailing spray nozzles in the direction of movement of the screen wiper resumes before the reverse position of the screen wiper is reached.
