www.ADandP.media RÖCHLING AD&P; ∕ NOVEMBER 2017 The Advanced Active Cleaning System prototype has been developed by Röchling and electronics expert Helbako. Shown here is a cutaway of the fluid tank and the electronics that are integrated with it. The purpose of the AACS is to keep the surfaces of radar, lidar, cameras and other sensors clean. The system intelligence not only determines what needs to be clean, but, based on the amount of fluid in the tank and the importance of the given sensors, which to prioritize to help assure safe driving. ability to attenuate sound that is provided by the ISF is all the more important (although it should be pointed out that it works just as effectively for non-EVs, too). And while on the subject of electrified vehicles, they are working on integrating a charging coil into the car's under- body. In this arrangement, a vehicle would simply need to be positioned above a primary coil in the ground and inductive charging would occur. It is also being designed with a geometry that allows higher power charging for a given size vehicle. Röchling's arrangement also uses an integrated metallic EMC cover so that there would be protection for other electronics in the vehicle during the charging cycle. In the area of sensors, the company is addressing the need to keep the outer surfaces of the radar, lidar, cameras and so on clean. It worked with electronics company Helbako The Röchling Integrated Sandwich Floor combines microperforated aluminum sheets that sandwich a composite core to provide an underbody structure that is stronger and lighter than conventional approaches. What's more, they're designing this ISF to (1) safely accommodate batteries and (2) provide the means by which inductive electric vehicle charging can be performed. ( helbako.de/en ) in developing what—still a prototype—is called the "Advanced Active Cleaning System" (AACS). Röchling has extensive experience in thermoplastic processing and the development of vehicular fluid tanks, such as those used for holding washer fluid. In the case of the AACS, they designed a tank that uses an integrated control system and features a thermal management unit to optimize water temperature within the tank. There is the necessary hose system to provide the cleaning fluid to the various locations around the car where the sensors are located. The system is able to flow the water to clean the surfaces of the sensors as needed. Notably, the AACS also takes into account the amount of fluid in the tank and then prioritizes which sensors to clean based on the driving conditions so as to help assure safe driving. 45
