We also need another system for good visibility: the windscreen wiper. Its most advanced stage currently is MAGIC VISION CONTROL, developed by Mercedes-Benz, and a highly effective innovation. It cleans the windscreen without causing the annoying jet of water on the glass we know from conventional windscreen washer systems that briefly restricts the driver's vision.
The wiper blade contains tiny discharge openings that transport the heated water directly to where it is needed: onto the windscreen directly ahead of the wiper lip. There is no sign of the cleansing jet of water, the occupants don't notice a thing and the windscreen is cleaned nonetheless – as if by magic. MAGIC VISION CONTROL even regulates the amount of water dependent on the time of year – less in summer for light dust, more in winter for heavier dirt and road salt. The washer fluid is discharged based on the ambient conditions, such as the outside temperature, the vehicle speed and the particular driving situation, for example. And in roadsters and cabriolets, MAGIC VISION CONTROL makes it possible to clean the windscreen without any spray mist, even with the top down.
Mercedes-Benz has repeatedly taken a close look at the windscreen wiper. Already the Benz predecessor brand was a pioneer: in 1905, car-loving Prince Heinrich von Preußen invented a system and realised it in his own Benz.
The F 100 research vehicle from Mercedes-Benz had a parallel windscreen wiper that ran horizontally across the windscreen – a revolutionary idea.
