A windshield wiper assembly for a vehicle having a drive device provided with an electric motor having a pole-well, and a transmission that can be driven by the electric motor, which is operatively connected to at least one wiper arm, and having a device for fastening the drive device to the vehicle. The device is provided with a tab surrounding the pole-well of the electric motor on the peripheral side, at least in some areas, which is provided with a free end, which protrudes from the pole-well and which is fastened to the vehicle.

Systems and methods for sensing accumulated residue on a transmission surface of a sensor of an agricultural machine and controlling a cleaning of the transmission surface. Using captured information obtained by the sensor through the transmission surface, a first cleanliness value can be derived and compared with a first threshold. If the first threshold is not satisfied, a cleaning system can be activated. Communication of signals generated using the captured information can also then be suspended or assigned a confidence value. Information subsequently captured by the sensor can be used to derive another cleanliness value for comparison to a second threshold. The subsequently derived cleanliness value can result in at least one of a change in the confidence value, resumption of communication of signals generated using captured information obtained by the sensor, deactivation of the cleaning system, and a change in the aggressiveness of the cleaning system.

Provided are embodiments for a direct drive wiper system. The system includes a motor that is operably coupled to a wiper system to drive one or more wiper arms of the wiper system, and a gearbox, wherein an input to the gearbox is coupled to the motor and an output of the gearbox is coupled to the wiper assembly, wherein the gearbox is configured to convert an input from the motor to an output to drive the wiper system. The system also includes a brake and stopper mechanism that is coupled to the gearbox and the wiper system. Also provided are embodiments for a method for operating the direct drive wiper system.
