The invention relates to a method for positioning a vehicle having a mobile inductive charging device in a defined position in relation to a stationary inductive charging device. The mobile inductive charging device or the stationary inductive charging device has a first sensor winding with a first radial longitudinal direction and a second sensor winding with a second radial longitudinal direction. The first radial longitudinal direction and the second radial longitudinal direction are arranged at an angle of between 70° and 110° in relation to one another, preferably perpendicularly in relation to one another, and at an angle of between 35° and 55° in relation to the longitudinal direction of the vehicle or to the target vehicle longitudinal direction, preferably at a 45° angle in relation to the longitudinal direction of the vehicle or in relation 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. The at least one first voltage signal is detected in a signal detection unit and the at least one second voltage signal is detected in a signal detection unit. An evaluation unit converts the first voltage signal into a first digital signal and the second voltage signal into a second digital signal and processes and compares the first digital signal and the second digital signal. Processing the first digital signal and the second digital signal includes transformation into the frequency range, and a direction deviation value between the longitudinal direction of the vehicle and the connecting line between the stationary inductive charging device and the mobile inductive charging device is calculated from the comparison of the first digital signal with the second digital signal.
