Method for positioning a motor vehicle, system with such a motor vehicle, and motor vehicle
First Claim
1. A method for positioning a motor vehicle in relation to a primary element of a charging device disposed on a side of a roadway of the motor vehicle for contactless charging of an electric storage device of the motor vehicle, comprising:
- moving a secondary element of the charging device arranged on the motor vehicle and interacting with the primary element relative to the primary element by moving the motor vehicle on the roadway relative to the roadway into a predetermined charging position,detecting with at least one sensor embodied as a distance sensor at least one positioning element constructed as a plurality of ridges and depressions arranged between the ridges,counting a number of ridges and depressions when the motor vehicle moves relative to the roadway and the secondary element passes over the positioning element,comparing the count of the number of passed ridges and depressions with a predefined number, anddetermining that the charging position has been reached when the number of passed ridges and depressions substantially coincides with the predefined number.

Abstract
A method for positioning a motor vehicle in relation to a primary element of a charging device disposed on a side of a roadway of the motor vehicle for contactless charging of an electric storage device of the motor vehicle, includes moving a secondary element of the charging device arranged on the motor vehicle and interacting with the primary element relative to the primary element by moving the motor vehicle on the roadway into a predetermined charging position, and determining with at least one sensor and at least one positioning element having at least two mutually different markers, when the secondary element has reached the predetermined charging position, by detecting the markers with the sensor.
