For example, a vehicle owner Information regarding the location of his vehicle when leaving record by means of a portable voice recorder and return to Parking or in the parking garage retrieve the stored information.

From the DE 299 09 002 U1 For example, a device for locating a parked vehicle is known in which the position data of a vehicle in a parking garage and / or data about the distance traveled in the parking garage are determined via an in-vehicle navigation system, which are transmitted to a storage unit and stored therein , The storage unit is integrated into a mobile terminal, which the driver can carry with him after leaving the vehicle. In addition, the mobile terminal has a display unit, with the help of which the position data of the vehicle stored in the memory unit and / or the data about the traveled route can be displayed. At the latest in a parking operation who thus recorded and stored via the navigation system information about the current position and / or the distance covered, so that the driver of the vehicle to locate his vehicle can rely on the stored information. In this way, a temporal decoupling of the storage of the location and route information and the later access to the stored location and route information by the driver is achieved. The information transmission from the navigation system or from the vehicle to the buffer takes place at a time when the driver is in the immediate vicinity of the vehicle and thus undisturbed information transmission between the mobile terminal and the navigation system provided in the vehicle is ensured. Disadvantage, however, such navigation systems do not provide floor or height information and are often due to the strong electromagnetic shielding properties of concrete ceilings in parking garages or underground garages not operational.

Also the radio power and thus the range of conventional Radio systems ("Radio Frequency Systems ") is through the building characteristics of parking garages and underground garages so reduced, allowing active communication with the vehicle to receive the current location information only conditionally possible is.

low Radio Systems ("Low Frequency ") Although have a sufficiently high wireless performance at a low Wireless range (100-300m) but are also for the data transmission over longer distances, especially within a parking facility not operational.

conventional Infrared systems require data transmission from an infrared transmitter unit to an arranged for example in a vehicle infrared receiver unit an undisturbed Line of sight, which often in parking garages or underground garages alone because of the large number of close ne next to each other parked vehicles and the partitions and support columns is not given.
