A system for the contactless transmission of energy from a primary winding to a vehicle comprising a secondary winding which can be inductively coupled to the primary winding, method for detecting metal pieces in the system, method for positioning a vehicle, method for determining a direction and a positioning control method, wherein the primary winding is arranged in a stationary manner and can be acted upon by an alternating current, wherein a winding arrangement is arranged in a stationary manner, said winding arrangement having a first winding and a second winding, in particular wherein the winding arrangement is arranged centrally with respect to the primary winding, wherein the first and second windings are each composed of at least two part windings, wherein the surfaces around which the part windings of a particular winding are wound are exposed to a magnetic flux generated by the primary winding and are spaced apart from one another, in particular in such a manner that no flux line of the flux generated by the primary winding passes through said surfaces together, wherein the part windings each have such a winding number and such a surface around which said part windings wind that the voltages of the part windings, which voltages are induced by the, in particular changing, magnetic flux of the primary winding are identical in magnitude, and in particular wherein the first winding is arranged rotated with respect to the second winding in such a manner that each part winding of the first winding is arranged inductively coupled to each part winding of the second winding.
(FR)
L'invention concerne un système de transmission d'énergie sans contact entre un bobinage primaire et un véhicule comprenant un bobinage secondaire qui peut être couplé inductivement avec le bobinage primaire, un procédé de détection de pièces métalliques dans le système, un procédé de positionnement d'un véhicule, un procédé de détermination d'une direction et un procédé de commande du positionnement. Le bobinage primaire est implanté de manière stationnaire et peut être parcouru par un courant alternatif. Un agencement de bobinages est implanté de manière stationnaire et comprend un premier et un deuxième bobinage et il est en particulier centré par rapport au bobinage primaire. Le premier et le deuxième bobinage sont composés chacun d'au moins deux bobinages élémentaires, les surfaces entourées par les bobinages élémentaires de chaque bobinage étant exposées à un champ magnétique produit par le bobinage primaire, et étant écartées l'une de l'autre en particulier de manière qu'elles ne soient pas traversées en même temps par une ligne de flux du flux produit par le bobinage primaire. Les bobinages élémentaires possèdent chacun un nombre de spires et une surface entourée tels que les tensions, en particulier variables, qui sont induites dans les bobinages élémentaires par le flux magnétique du bobinage primaire soient de même valeur, en particulier que le premier bobinage soit disposé pivoté par rapport au deuxième bobinage pour que chaque bobinage élémentaire du premier bobinage soit couplé inductivement avec chaque bobinage élémentaire du deuxième bobinage.
