Although, traditionally, the rain became more and more present in winter than in summer, l as weather conditions we are leaving lately big surprises, with cloudbursts of tragic consequences. That is why it is essential to take care of the conditions of the windshield wipers, which do not always work as it should, leaving some unpleasant traces to the time of work, in addition to noises.
But in addition the windshield is a key element in the systems ADAS (Advanced Driving Assistance) and in the driving region. Both technologies are in need of cameras and sensors that detect everything that happens around the car and collect the information, and then act accordingly and help the driver or even a maneuver. The vast majority of cameras systems ADAS are mounted on the windshield, always in a similar location: in the upper center portion, to the height of the inside rearview mirror. From there have a high view and clear, as are within the zone of sweep of the windshield wipers.
On the windshield with panoramic views, which stretch toward the ceiling, the cameras of the systems ADAS could be installed much higher up to clear even more of the driver's vision . But there is a problem: the wipers do not reach to clean that area, so that the cameras cannot be mounted there. The conventional systems are not effective in windshield is very curved
With the aim of resolving this drawback, Tesla –whose model X has the windshield the world's largest, named Big Sky - has registered a patent for a new windshield wiper system, q eu would cover the entire surface of a windshield . This system also brings other benefits: it consumes less electricity and provides a better aerodynamic coefficient, which improves the fuel consumption; and has a lower maintenance, more durability and a design that is more refined.
the patent explains that “in certain situations, a driver, or the on board cameras of a vehicle (for example, driving-assisted and autonomous) require a field of vision free of what there is ahead of the vehicle. The wiper systems-conventional, with several to wiper blades, they usually have a little design refined and do not clean the entire windshield, which could hinder the field of vision.”
it Also relates to electric motors which include many mechanical components that create a friction that requires a lot of energy to the battery, are susceptible to oxidation and wear, especially true in geographical areas subject to adverse weather conditions ; and have a variable influence on the aerodynamics, by changing the vector of the flow of air.
The new system of Tesla is based on a mechanism of electromagnetic radiation, in which the arm of the clean slides transversely along the entire windshield for a few lanes. This mechanism hides under the hood when not in operation. In this way, it is possible to cover the entire surface of the windshield and install the camera systems in ADAS above. In addition, it significantly reduces the friction and improves the aerodynamics, which has an impact on the fuel consumption; and eliminating many mechanisms susceptible to corrosion with the passage of time.
As explained by the specialists Carglass, when you replace a windshield, you must disassemble the camera from the broken glass and reassemble in the new. Once installed, these systems must be recalibrated to ensure that they work with maximum accuracy and provide the correct information to the security systems.
