A system for a vehicle wiper is disclosed. The system comprises a first rain sensor disposed on a fore portion of a vehicle and a second rain sensor disposed on an aft portion of the vehicle. The system further comprises a controller configured to suspend a rain sensing activation identified during a monitoring cycle in response to a control event. The control even comprises detecting moisture with the first rain sensor for a delay time without detecting the moisture with the second rain sensor.

A windshield wiper operating system is provided for a semi-autonomous motor vehicle. That windshield wiper operating system includes a windshield wiper, a windshield wiper drive motor and a controller configured to deactivate the windshield wiper operation when raining and the semi-autonomous motor vehicle is in autonomous driving mode. A related method is also disclosed.

A wiper control system includes: a multifunction switch detecting and transmitting an operation of a wiper provided on a vehicle; a body control module controlling a wiper relay through a data signal of the multifunction switch; and a wiper motor connected to the multifunction switch and the body control module and connected to the wiper to rotate the wiper according to rotation of a cam plate of the multifunction switch and detect a parking end of the body control module, thereby preventing the wiper from being positioned in a middle of a windshield glass.

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.

A system for detecting noise generated by a windshield wiper on a vehicle including a cabin is provided. The system includes a detector for detecting noise generated by the windshield wiper. A processor is provided for generating a signal based on the noise detected by the detector. A controller may also receive the signal and regulate the operation of the windshield wiper, including by adaptive control based on a vehicle operator's desired setting of a speed of the wiper in an intermittent mode of operation. The signal may also be used to notify a service provider of the need for servicing the windshield wiper. Related methods are also disclosed.

A wiping device for an optical device with a lens includes a surface, such as a curved or calotte-shaped surface, where the wiping device has a wiping element for wiping the surface of the lens free from water and dirt particles with at least one passage channel and at least one outlet channel which branches off from the passage channel in order to guide cleaning fluid onto the surface of the lens. In addition, a rear view device for a motor vehicle with an optical device includes such a wiping device.

The invention relates to a method 100 for monitoring the use of a wiper system of a motor vehicle 1, comprising the following steps: a step of collecting at least one item of data relating to the triggering of the wiper system 10, a step of collecting at least one item of data relating to the vehicle 1 and/or to its environment, a step of transforming at least one of the items of data collected in the previous steps into a value, termed monitoring value, a step of comparing the monitoring value with a value, termed predetermined threshold value, a step of recording at least one of the collected items of data when the monitoring value reaches or exceeds the predetermined threshold value.

The invention also relates to a wiper system 10 comprising a control unit designed to implement the method such as described above.
