Abstract

The invention relates to a windshield wiping device (1), in particular for a motor vehicle, comprising at least one driving device (2) which can be controlled by a control device (3), said control device (3) controlling a power and torque requirement of the windshield wiping device (1) dependent on at least one or more parameters influencing the power and torque requirement of the driving device (2). The invention is characterized in that the control device (3) has at least parameters for determining the current position of the motor vehicle to reduce the power and torque.

Claims

1. A windshield wiping device for a motor vehicle, the windshield wiping device comprising:

at least one drive device, which can be controlled via a control device, the control device controlling a power and torque requirement of the windshield wiping device depending on at least one or a plurality of parameters influencing the power and torque requirements of the drive device, wherein the control device comprises, in order to reduce the power and torque, at least parameters for determining the present position of the motor vehicle.

2. The windshield wiping device as claimed in claim 1, wherein the determination of the position of the motor vehicle is performed with the aid of satellite signals.

3. The windshield wiping device as claimed in claim 1, wherein the control device is coupled to a GPS provided in the motor vehicle in order to determine the parameters of the vehicle position.

4. The windshield wiping device as claimed in claim 1, wherein the parameters at least contain the maximum permissible travel speed.

5. The windshield wiping device as claimed in claim 4, wherein the control device is coupled to a cruise control system provided in the motor vehicle in order to determine the parameter of travel speed.

6. The windshield wiping device as claimed in claim 1, wherein the control device is coupled to a camera system provided on the vehicle, said camera system determining local speed limits depending on the vehicle position, it being possible for the speed limit to be used to communicate the parameter of travel speed.

7. The windshield wiping device as claimed in claim 1, further comprising at least one rain sensor for determining environmental conditions and/or a windshield state of the vehicle.

8. The windshield wiping device as claimed in claim 1, wherein the parameters comprise at least one of wiper arm angles, a direction of wiping movement direction, a transmission ratio of a wiper arm rod assembly of the windshield wiping device, and a wiper speed.

9. The windshield wiping device as claimed in claim 1, wherein the power and torque matching takes into consideration an upward wiper movement and/or a downward wiper movement, and the control device is configured to call up at least one or a plurality of families of characteristics to determine the required power and torque.

10. A method for electronically controlled limitation of a power and torque of a windshield wiping device for a motor vehicle, the method comprising:

controlling the windshield wiping device via a control device, which controls a power and torque requirement of the windshield wiping device depending on at least one or a plurality of parameters having an influence on the power requirement of the drive device;

determining one or more parameters, wherein the parameters include at least the present position of the vehicle and/or the maximum permissible travel speed and/or travel speed which can be set via a cruise control system; and

controlling the power and torque requirement of the windshield wiping device depending on the respective parameters.

11. The method as claimed in claim 10, wherein a wiper arm angle, a wiping movement direction, a transmission ratio of a wiper arm rod assembly of the windshield wiping device, a wiper speed, a transmission ratio of a drive rod assembly, an external temperature and/or a windshield state are taken into consideration as parameters.
