Abstract: A system includes a vehicle and an induction charging unit, where the induction charging unit includes a primary coil and the vehicle includes a secondary coil. During a charging operation in a charging position, electric power is inductively transmissible from the primary coil to the secondary coil, in the charging position, the secondary coil being situated in a preferred spatial position area with respect to the primary coil, such that, for setting the charging position, by means of electromagnetic distance and angle measuring, by triangulation, the system detects a location position which describes a time-dependent spatial position of the secondary coil with respect to the primary coil. Moreover, by means of the location position and the charging position, the system detects at least a partial travel trajectory, along which the location position of the charging position can be approximated.

Abstract: An assistance system for assisting the driver of a motor vehicle when positioning the motor vehicle at a predefined target position is provided. The target position is preferably a charging position for wireless, in particular inductive, charging of the motor vehicle. In order to position the motor vehicle, the longitudinal movement of the vehicle can be controlled manually by one or more operator control elements (e.g., accelerator pedal, brake pedal) which can be actuated by the driver. The assistance system assists the manual longitudinal control during positioning. The assistance system serves to influence the manual longitudinal control. By influencing the manual longitudinal control, the assistance system counteracts, as a function of the respective position information, the longitudinal movement of the vehicle at least for certain relative positions, in order to bring the vehicle to a stop essentially at the target position.
