Abstract

A method for washing a window of a vehicle, using at least one wiper blade member and a liquid projector that projects liquid for washing the window onto a wiping surface has a first wiping cycle including a first step of actuating the wiper blade member to move over the window in a first direction from a first starting position to a wiping end position, while projecting the liquid onto the wiping surface, and a second step of actuating the wiper blade member to move over the window in a second direction opposite the first direction from the wiping end position to the first starting position, and a second wiping cycle including a third step of actuating the wiper blade member to move over the window in the first direction from the first starting position to the wiping end position, while projecting the liquid onto the wiping surface.

First claim

The invention claimed is:

1. A method for washing a window of a vehicle, using at least one wiper blade member and a liquid projector that projects liquid for washing the window onto a wiping surface, comprising:
a first wiping cycle, comprising:
a first step of actuating the wiper blade member to move over the window in a first direction from a first starting position to a wiping end position, while projecting the liquid onto the wiping surface, and
a second step of actuating the wiper blade member to move over the window in a second direction opposite the first direction from the wiping end position the first starting position;

a second wiping cycle, comprising:
a third step of actuating the wiper blade member to move over the window in the first direction from the first starting position to the wiping end position, while projecting the liquid onto the wiping surface, and
a fourth step of actuating the wiper blade member to move over the window in the second direction from the wiping end position to a second starting position; and

a third wiping cycle, comprising:
a fifth step of actuating the wiper blade member to move over the window in the first direction from the second starting position to the wiping end position, while projecting the liquid onto the wiping surface, and
a sixth step of actuating the wiper blade member to move over the window in the second direction from the wiping end position to a third starting position, the second starting position, or the first starting position,

wherein the first starting position is farther away from the wiping end position than the second starting position, and
wherein the second starting position is farther away from the wiping end position than the third starting position.

2. The method according to claim 1 , wherein the first starting position and second starting position are located in a predetermined zone that minimises a spread of dust over the wiping surface outside the predetermined zone.

3. The method according to claim 1 , wherein, in the third step or the fifth step, the liquid projector is actuated to project washing liquid in front of the wiper blade member relative to the first direction.

4. The method according to claim 1 , comprising a fourth wiping cycle comprising:
a seventh step of actuating the wiper blade member to move over the window in the first direction from the third starting position, the second starting position, or the first starting position to the wiping end position, without projecting the liquid onto the wiping surface, and
an eighth step of actuating the wiper blade member to move over the window in the second direction from the wiping end position to the third starting position, the second starting position, or the first starting position, without projecting the liquid onto the wiping surface.

5. The method according to claim 1 , wherein the first starting position of the first wiping cycle which is carried out is substantially the same as a wiping starting position.

6. The method according to claim 1 , wherein the first starting position is a parking position which is further away from the wiping end position than a wiping starting position.

7. The method according to claim 1 , wherein the second step, the fourth step, and the sixth step are carried out without actuating the liquid projector.

8. The method according to claim 1 , wherein the wiper blade member moves over the window upwards during the first step, the third step, and the fifth step.

9. A control device for a system for wiping and washing a window of a vehicle comprising a wiper blade member, an actuator that actuates the wiper blade member, and a liquid projector that projects a liquid for washing the window, the device comprising:
an electronic member programmed to actuate the actuator of the wiper blade member and the liquid projector to perform:
a first wiping cycle, comprising:
a first step of actuating the wiper blade member to move over the window in a first direction from a first starting position to a wiping end position,
while projecting the liquid onto the wiping surface, and
a second step of actuating the wiper blade member to move over the window in a second direction opposite the first direction from the wiping end position to the first starting position;

a second wiping cycle, comprising:
a third step of actuating the wiper blade member to move over the window in the first direction from the first starting position to the wiping end position, while projecting the liquid onto the wiping surface, and
a fourth step of actuating the wiper blade member to move over the window in the second direction from the wiping end position to a second starting position; and

a third wiping cycle, comprising:
a fifth step of actuating the wiper blade member to move over the window in the first direction from the second starting position to the wiping end position, while projecting the liquid onto the wiping surface, and
a sixth step of actuating the wiper blade member to move over the window in the second direction from the wiping end position to a third starting position, the second starting position, or the first starting position,

wherein the first starting position is farther away from the wiping end position than the second starting position, and
wherein the second starting position is farther away from the wiping end position than the third starting position.

10. A system for wiping and washing a window of a vehicle, the system comprising:
a wiper blade member;
an actuator that actuates the wiper blade member which are arranged so that the wiper blade member moves over the window;
a liquid projector that projects a liquid for washing the window configured to project the washing liquid in front of the wiper blade member; and
a control device, comprising an electronic member programmed to actuate the actuator of the wiper blade member and the liquid projector to perform:
a first wiping cycle, comprising:
a first step of actuating the wiper blade member to move over the window in a first direction from a first starting position to a wiping end position, while projecting the liquid onto the wiping surface, and
a second step of actuating the wiper blade member to move over the window in a second direction opposite the first direction from the wiping end position to the first starting position;

a second wiping cycle, comprising:
a third step of actuating the wiper blade member to move over the window in the first direction from the first starting position to the wiping end position, while projecting the liquid onto the wiping surface, and
a fourth step of actuating the wiper blade member to move over the window in the second direction from the wiping end position to a second starting position; and

a third wiping cycle, comprising:
a fifth step of actuating the wiper blade member to move over the window in the first direction from the second starting position to the wiping end position, while projecting the liquid onto the wiping surface, and
a sixth step of actuating the wiper blade member to move over the window in the second direction from the wiping end position to a third starting position, the second starting position, or the first starting position,

wherein the first starting position is farther away from the wiping end position than the second starting position, and
wherein the second starting position is farther away from the wiping end position than the third starting position.

11. The system according to claim 10 , wherein the actuator comprises a motor which can be ontrolled electronically and an arm for driving the wiper blade member, the motor rotatably driving the drive arm.
