Patent ID: 8909421

Claim:
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.
