The world’s smallest windshield wiper ensures the safety of Hyundais

Hyundai Motor Group is developing a new device that ensures active safety technology works even when things get tough.

The company has filed a patent for a Rotator Cam, a technology designed to keep its cars’ camera sensors clean.

Accordingly Korean auto blogAI technology is used to monitor whether the camera lens is blocked by dirt or small foreign objects.

The cleaning process essentially takes place in three steps.

The electric motor inside the Rotator Cam rotates the camera’s cover glass while a small amount of washing fluid comes out from below to remove dirt. A wiper then removes excess washing fluid.

Hyundai Motor Group isn’t the first to develop technology that cleans a vehicle’s camera – BMW and Volkswagen Group are doing it too.

However, most other camera cleaners may leave excess washing fluid on the cover glass because they do not include a wiper.

Using a device to rotate the camera’s cover glass reduces the need for additional cleaning if the wash fluid splash cannot remove all the dirt from a portion of the glass.

Korean Car Blog reports that Hyundai Motor Group plans to evaluate the technology for mass production after performance and durability tests.
