Embodiment Construction
[0033] The vehicle (4) drives onto the induction disc (3) from either side and automatically recognizes the charging coils on the ground in the automatic search mode of the radar activated by the preset device or in the manually activated search mode. In the presetting device, for example, the user can define the automatic activation of the search mode in the vicinity of frequently traveled destinations, such as a place of work or a place of purchase. Or the user may simply drive over the coil by visual approximation without radar localization.
[0034] All charging pads are continuously checked in the immediate surroundings from database entries by plausibility comparisons of the navigation system. Based on a simple driver command, the navigation system also directs the driver to the nearest charging station or the next available charging station if a preferred telematics option with a corresponding return channel is included in the vehicle.
[0035]After performing a plausi...

Abstract
The present invention relates to a system that ensures a self-guiding, electronic positioning of a secondary coil at a vehicle side, without the aid of indicators or kinematic or mechanical aids, in relation to a primary coil that is fixed at a a ground side, 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 at the ground side fulfils 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 at the ground side 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 natural protection or for intralogistics.
