摘要： 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.

摘要： 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.

摘要： Since a shape of a stator 44 is made mirror symmetric with respect to a rotor 45 as a 4-pole/6-slot type, rotational deflection of the rotor 45 can be suppressed. As the minimum number of poles and the minimum number of slots, which can suppress the rotational deflection of the rotor 45, a frequency of magnetic noises approaches a frequency of mechanical noises. Thus, it is possible to integrate the whole noises generated by the DR-side wiper motor 21 into a low frequency range thereof, and to make the acoustic sensitivity (dB) of a vehicle interior smaller. Since the stator 44 is fixed inside a housing 40 and mounting legs fixed to a vehicle body fixed portion are provided in the housing 40, the stator 40, which is a source of the magnetic noises, can be fixed to a vehicle via only the housing 40. Therefore, a brushless wiper motor with quietness improved further can be designed.

摘要： A vehicular wiper device is provided with a snowfall determination unit that determines whether a predetermined snowfall condition is satisfied. When the snowfall determination unit determines that a predetermined snowfall condition is satisfied, a controller that controls a wiper motor changes lower reverse positions of wiper blades to lower reverse positions during snowfall that are on the lower side with respect to lower reverse positions during normal times.

摘要： A windshield wiper assembly for a dual sweep angle and indexable wiper system is provided. The system includes a wiper motor and a wiper arm for sweeping a surface of a windshield coupled to a first eccentric, the first eccentric comprising a primary eccentric and an indexable eccentric plate, wherein the indexable eccentric plate determines an eccentric offset of the wiper arm coupled to the first eccentric. The system further includes an output wiper shaft coupled to the wiper arm, a second eccentric coupled to a cam shaft, and a link coupled to the first eccentric and the second eccentric, the link having a first effective link arm length between the first eccentric and the second eccentric for driving the first eccentric to operate the wiper arm when operated in a first direction.
