SYSTEM FOR INDUCTIVELY CHARGING VEHICLES, COMPRISING AN ELECTRONIC POSITIONING AID
First Claim
1. Electronic positioning aid for electric vehicles in the near vicinity of inductive charging stationswhereinsensors present in the vehicle or optionally provided therein, based on radar, laser, lidar, ultrasound, infrared, satellite or induction and the parking aids based thereon are additionally used to recognize inductive charging stations in the near vicinity fully automatically based on the station-side coil housing or the internal coil technology, without visual environment representation, without manual user input and without additional station-side reflectors, and to position the vehicle in the computer-assisted parking operation with the coil in the bottom of the vehicle sufficiently accurately above the station-side coil, without the two coils having to be brought into a more precise or closer superimposition with additional moving or lifting devices.

Abstract
The main claim involves a system that ensures a self-guiding, electronic positioning of a secondary coil in a vehicle, without the aid of indicators or kinematic or mechanical aids, in relation to a primary coil that is fixed in a structure, in order to guarantee a transfer of energy with over 90% efficiency without the disadvantages of moving, frictional and elastic components in terms of energy consumption, functional safety and wear. To achieve this aim, the coil housing in the structure fulfills the role of an electronics housing, reflective element and cooling element thanks to the choice of material used, the surface and the inner supports and can thus be retrofitted, as a single installation on the structure in the form of an operation-ready complete package, to any flat base with an electric connection. The vehicle can be used both for transporting passengers and loads and can be steered by a vehicle driver or can be operated without a driver, for example for cleaning areas, for the protection of the countryside or for intralogistics

4. Ground-side coil housing for an inductive charging station,
wherein the station-side coil housing preferably simultaneously serves as a highly characteristic reflector for the vehicle-side scanning sensors, the circumferential concave rising edge constituting a reflector for the radar signal in a wide range of distances and simultaneously for a wide range of approach angles, due to the circular base surface.
