The invention relates to a method for positioning a vehicle having a mobile inductive charging device in a defined position relative to a stationary inductive charging device. The mobile inductive charging device or the fixed inductive charging device includes a first sensor winding having a first radial longitudinal direction and a second sensor winding having a second radial longitudinal direction. The first radial longitudinal direction and the second radial longitudinal direction are arranged at an angle of between 70 DEG and 110 DEG relative to each other, preferably perpendicular to each other, and at an angle of between 35 DEG and 55 DEG with respect to the longitudinal direction of the vehicle or with respect to a target vehicle longitudinal direction, preferably at an angle of 45 DEG with respect to the longitudinal direction of the vehicle or with respect to the target vehicle longitudinal direction. A positioning signal generates a first voltage signal in the first sensor winding and a second voltage signal in the second sensor winding. At least one first voltage signal is detected in the signal detection unit, and at least one second voltage signal is detected in the signal detection unit. An evaluation unit converts the first voltage signal into a first digital signal and converts the second voltage signal into a second digital signal, and processes and compares the first digital signal and the second digital signal. The processing of the first digital signal and the second digital signal includes a transformation into a frequency range, and calculating a directional deviation value of a longitudinal direction of the vehicle relative to a connection line between the fixed inductive charging device and the mobile inductive charging device according to a comparison of the first digital signal and the second digital signal.
