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.

An image inpainting method includes the following steps: segmenting image, acquiring a plurality of images, and having the plurality of images segment into noise-contained pixel images and non-noise-contained pixel images, and confirming the positions of every noise pixel of the noise pixel image; and performing inpainting in light of the noise-contained pixel images, finding out the offset map and geometric relationship of the pixel corresponding relationship without being subjected to the affection of noise and having the pixel corresponding relationship with minimum parallax, making use of the offset map or the geometric relationship to extract corresponding pixel that is not subjected to the affection of noise, performing inpainting and substituting the noise pixel in the plurality of images to generate at least a synthetic image without containing noise.

A wiper drive device includes: a wiring connected to a wiper motor; a drive element configured to apply a voltage to the wiper motor through the wiring by being turned on so as to rotate the wiper motor; a braking element configured to brake the wiper motor by being turned on when the drive element is turned off so as to flow a current corresponding to a rotational energy of the wiper motor; and a determination unit configured to determine that the braking element is abnormal when a time period from when the wiper motor is braked to when an electric potential of the wiring becomes equal to or less than a predetermined threshold potential is longer than a predetermined value which is the time period in case where the braking element is normal.

The wiper device includes a first pivot shaft, a first swing lever, a second pivot shaft, a second swing lever, a link rod, a crank arm, and a drive rod. The first swing lever extends from the first pivot shaft in a radial direction of the first pivot shaft. The second swing lever extends from the second pivot shaft in a radial direction of the second pivot shaft. The link rod has a first end connected to a tip part of the first swing lever and a second end connected to a tip part of the second swing lever. The crank arm extends from an output shaft of a motor in a radial direction of this output shaft. The drive rod has a first end connected to a tip part of the crank arm and a second end connected to an intermediate part of the link rod.

A wiping device for wiping an optical element clean of water or of particles includes a housing and a wiping element able to undergo a movement with respect to the housing, where the wiping device is configured to move in such a manner that such movement is caused by coupling a first unit in or on the wiping element with a second unit in the housing via a time-variable electromagnetic field. The wiping device may be used for wiping the surface of a lens or of a window, which lens or window is transmissive to visible light, ultraviolet radiation, and/or infrared radiation, and is preferably placed in front or as part of a camera. In addition, a rear view device or driver assistant device for use in or on a vehicle including such a wiping device, and a method for wiping an optical element are provided.

Systems and methods for cleaning transmission surfaces for optical and sensor surfaces in order to maintain optimal performance under a variety of weather and environmental conditions using synthetic jet actuators. The actuators can emit a jet of water or air depending on environmental conditions and the waveform, frequency, amplitude of the actuator can be adjusted based on particle characteristics and transmission signal quality in order to better clean the surfaces.
