Abstract
A process for active cleaning of a vehicle window with a movable window wiping arm carrying a wiping blade and with cleaning fluid supply onto the windowpane includes initiating movement of the wiping arm and subsequently applying a prescribed first quantity of cleaning fluid at a defined side of the wiping arm facing a first moving direction of the wiping arm. In an embodiment, a second prescribed quantity of cleaning fluid is applied that is smaller than the first quantity at the defined side during movement of the wiping arm in a second moving direction opposite the first moving direction.
Claims17
Process for active cleaning of window panes of a motor vehicle with a window wiper arm that comprises a wiping blade and mechanisms for application of cleaning fluid onto the window pane whereby the mechanisms for the application of the cleaning fluid are arranged in such manner that, in relation to a longitudinal direction of the wiping blade, the cleaning fluid is applied to a defined side of the wiping blade, said process comprising:
- waiting for activation of an active cleaning switch;
- applying a prescribed first quantity of cleaning fluid after a start of the activation of the active cleaning switch when the window wiper arm is moving in a direction of the defined side of the wiping blade;
- and
- applying a prescribed second quantity of cleaning fluid that is smaller than the first quantity, when the window wiper arm is moving in an opposite direction to the defined side.
Process for active cleaning of window panes of a motor vehicle with a window wiper arm that comprises a wiping blade and mechanisms for application of cleaning fluid onto the window pane whereby the mechanisms for the application of the cleaning fluid are arranged in such manner that, in relation to a longitudinal direction of the wiping blade, the cleaning fluid is applied to a defined side of the wiping blade, said process comprising:
- waiting for activation of an active cleaning switch;
- and
- applying a prescribed first quantity of cleaning fluid after a start of the activation of the active cleaning switch when the window wiper arm is moving in a direction of the defined side of the wiping blade;
- wherein an entire wipe-angle area is divided at least into two angle areas including a first no-wash area and a second wash area;
- and
- wherein the prescribed first quantity of the cleaning fluid is applied only in the second wash area.
Process for active cleaning of window panes of a motor vehicle with a window wiper arm that comprises a wiping blade and mechanisms for application of cleaning fluid onto the window pane whereby the mechanisms for the application of the cleaning fluid are arranged in such manner that, in relation to a longitudinal direction of the wiping blade, the cleaning fluid is applied to a defined side of the wiping blade, said process comprising:
- waiting for activation of an active cleaning switch;
- and
- applying a prescribed first quantity of cleaning fluid after a start of the activation of the active cleaning switch when the window wiper arm is moving in a direction of the defined side of the wiping blade;
- wherein the cleaning fluid is applied dependent on an angle of the window wiper arm;
- wherein an entire wipe-angle area is divided at least into two angle areas including a first no-wash area and a second wash area;
- and
- wherein the prescribed first quantity of the cleaning fluid is applied only in the second wash area.

- waiting for activation of an active cleaning switch;
- and
- applying a prescribed first quantity of cleaning fluid after a start of the activation of the active cleaning switch when the window wiper arm is moving in a direction of the defined side of the wiping blade;
- wherein the cleaning fluid is applied dependent on an angle of the window wiper arm;
- and
- wherein, at an activation of the active cleaning switch for a longer time period than for a prescribed time frame after release of the active cleaning switch there follows at least one additional complete wiping cycle with application of cleaning fluid in a second washing program.
Process for active cleaning of a vehicle window with a movable window wiping arm carrying a wiping blade and with cleaning fluid supply onto a windowpane, said process comprising:
- initiating movement of the wiping arm;
- subsequently applying a prescribed first quantity of cleaning fluid at a defined side of the wiping arm facing a first moving direction of the wiping arm;
- and
- applying a second prescribed quantity of cleaning fluid that is smaller than said first quantity at said defined side during movement of the wiping arm in a second moving direction opposite the first moving direction.
