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.
Claims16
A windshield wiping device for a motor vehicle, the windshield wiping device comprising:
- a controller configured to
- determine a first power and torque setting based on a first set of ambient conditions, the first set of ambient conditions including a current position of the motor vehicle,
- wherein the ambient conditions influence a power and torque necessary to move the windshield wiper across the windshield of the motor vehicle at a target non-zero speed,
- determine a second power and torque setting based on a second set of the ambient conditions, the second set of the ambient conditions including an updated position of the motor vehicle,
- wherein the second power and torque setting is different than the first power and torque setting, and
- wherein the second power and torque setting is determined based on a power and torque necessary to move the windshield wiper across the windshield of the motor vehicle at the same target non-zero speed under the second set of the ambient conditions as the first power and torque setting under the first set of the ambient conditions;
- at least one drive device, the drive device configured to move the windshield wiper across the windshield of the motor vehicle at the target non-zero speed based upon
- the first power and torque setting after determining the first power and torque setting and before determining the second power and torque setting, and
- the second power and torque setting after determining the second power and torque setting.
A method for controlling movement of a windshield wiper across a windshield of a motor vehicle, the method comprising:
- determining, by a controller, a first power and torque setting based on a first set of ambient conditions, the first set of ambient conditions including a current position of the motor vehicle,
- wherein the ambient conditions influence a power and torque necessary to move the windshield wiper across the windshield of the motor vehicle at a target non-zero speed;
- operating a drive device based upon the first power and torque setting to move the windshield wiper across the windshield of the motor vehicle at the target non-zero speed;
- determining, by the controller, a second power and torque setting based on a second set of the ambient conditions, the second set of the ambient conditions including an updated position of the motor vehicle,
- wherein the second power and torque setting is different than the first power and torque setting, and
- wherein the second power and torque setting is determined based on a power and torque necessary to move the windshield wiper across the windshield of the motor vehicle at the same target non-zero speed under the second set of the ambient conditions as the first power and torque setting under the first set of the ambient conditions;
- and
- operating the driver device based upon the second power and torque setting to move the windshield wiper across the windshield of the motor vehicle at the target non-zero speed.
