Description

The invention relates to a method for operating a charging park for charging electrically driven vehicles and a charging park, in particular for carrying out the method.

In order to trigger certain functions on charging stations of charging parks, it is necessary to sense the surroundings of the respective charging station. This concerns the detection of vehicles approaching a charging point in the charging park, where they are parked or determining the distance of a vehicle to the charging station.

Ultrasonic sensors, contact loops in the ground in front of the charging station, video cameras or devices that work on an infrared basis are used for this purpose.

In the case of charging parks in which electrically driven vehicles are not charged via charging cables but contactless, sensors are used for the optimal determination of the position of the vehicle to be charged relative to the charging station. This exact positioning of the vehicle is required in order to allow optimal energy transfer of energy from an alternating magnetic field of a primary coil of the charging station in a secondary coil associated with the vehicle.

From the DE 10 2014 224 455 A1 is a method for contactless charging an electrically powered vehicle with a parking lot associated charging station known. Here, a parking position is first transmitted to the vehicle. Then, the vehicle is guided to the parking position, wherein the position of the vehicle by the reception of signals of at least two transmitters, which are arranged at different positions, is determined. After reaching the parking position the energy transfer is released. In order to improve the accuracy of the position determination when guiding the vehicle to the parking position, additional data of further sensors present in the vehicle are used in addition, such as, for example, magnetic field sensors, radar sensors, cycle path sensors or ultrasound sensors.

Object of the present invention is to provide a particularly simple method for operating a charging park for charging electrically powered vehicles, also an advantageous design of the charging park for performing this method.

The object is achieved by a method according to claim 1 and a loading park according to claim 16. Advantageous developments of this method and this charging park are the subject of the dependent claims.

1. a) Bereitstellen eines Ladeparks mit mehreren Stellplätzen für elektrisch antreibbare Fahrzeuge, wobei dem jeweiligen Stellplatz eine Ladevorrichtung zum Aufladen des auf dem jeweiligen Stellplatz abgestellten Fahrzeugs zugeordnet ist, ferner mit mindestens einem Radarsensor zur Erfassung der jeweiligen Position eines oder mehrerer im Ladepark befindlicher Fahrzeuge,
2. b) Einfahren des jeweiligen Fahrzeugs in den Ladepark,
3. c) Abstellen des Fahrzeugs auf einem der Stellplätze, wobei mindestens ein Radarsensor das Abstellen des Fahrzeugs auf diesem Stellplatz erfasst,
4. d) Übermitteln der von dem mindestens einen Radarsensor erfassten Daten an eine Auswerteeinrichtung.

The method according to the invention for operating the charging park for charging electrically driven vehicles has the following method steps:

1. a) providing a charging park with several parking spaces for electrically driven vehicles, the respective parking space being assigned a charging device for charging the vehicle parked on the respective parking space, furthermore having at least one radar sensor for detecting the respective position of one or more vehicles located in the charging park,
2. b) driving the respective vehicle into the loading park,
3. c) parking the vehicle on one of the parking spaces, wherein at least one radar sensor detects the parking of the vehicle on this parking space,
4. d) transmitting the data acquired by the at least one radar sensor to an evaluation device.

In this method, the respective vehicle thus requires no active transmitter / receiver. It is a purely passive system. Thus, the parking of the respective vehicle is detected on the parking space by means of at least one radar sensor. The data acquired by the radar sensor, relating to this vehicle, are transmitted to the evaluation device. These data can be evaluated by the evaluation device under a variety of aspects.

Because it is a passive system, obstacles such as a garbage bin or the like can be detected in the loading park.

The respective parking space is preferably assigned a radar sensor for detecting the position of a vehicle located in the charging park, wherein the radar sensor assigned to this parking space detects the parking of the vehicle on this parking space.

In the case of several radar sensors, in particular charging stations with radar sensors associated with the respective charging station, a radar sensor array results, which increases the robustness and accuracy of the method for operating the charging park. In particular, several radar sensors overlap the charging park to create a charging park representing radar image.

According to a preferred development of the method according to the invention, it is provided that the evaluation unit activates the charging device associated with the parking space on which the vehicle was parked, such that the charging device, when the vehicle is parked on the parking space, switches from a rest state in which the vehicle is charged the charging device is not possible, in an operating state in which a charging of the vehicle by means of the charging device is possible, changes. The evaluation device thus enables the implementation of a wake-up function in the charging device, in particular in an electronics of the charging device, in order to change to a ready-to-charge state.

Preferably, the method is developed in such a way that the evaluation device, which controls the charging station assigned to the parking space on which the vehicle was parked, such that when the vehicle is removed from the parking space, the charging device changes from the operating state to the idle state. Thus, a sleep function of the charging device, in particular the electronics of the charging device, is controlled in order to change to the non-charging state of the charging device.

According to a preferred development of the method, it is provided that a display is assigned to the respective parking space and the evaluation device uses the transmitted data to determine the position of the vehicle with respect to the loading device assigned to the parking space. In this case, the evaluation device controls the display in such a way that it indicates to a driver of the vehicle that a certain position with respect to the loading device has been reached or supports the driver of the vehicle when starting up this position. This support is thus passive. The evaluation unit determines, by means of the transmitted data, in particular the distance of the vehicle with respect to the loading device assigned to the parking space.

According to a further development, it is provided that the evaluation device determines a duration from a parking of the vehicle on the parking space up to a removal of this vehicle from this parking space. Thus, the parking duration of the vehicle can be reliably detected in the charging park.

According to one embodiment, it is provided that the respective parking space is assigned a further display, wherein the evaluation device controls the further display such that this further display displays information for the driver of the vehicle, in particular information about a kWh price of the charge and / or one Loading progress and / or a residual charging time. This information may well be promotional information. If the respective charging device is designed as a charging station, the display is designed in particular as a display of the charging station. The further display can be controlled in such a way that it indicates to the driver of the vehicle to move closer to the charging station so that a charging cable can be plugged into a charging cable receptacle of the charging station.

According to a further development of the method, it is provided that the evaluation device activates an ambient lighting assigned to the parking space when the vehicle is parked on the parking space.

Advantageously, the radar sensors are directly connected to one another in a communication connection and / or the radar sensors are in communication connection with a common evaluation device. It is thus possible to communicate between the charging devices, in particular charging stations or communication to a higher-level supervisory authority.

In particular, the common evaluation device performs a sensor data fusion. Several sensor readings are combined for a higher-level radar image between the charging stations or between the charging stations.

In particular, the radar sensors are introduced into the charging stations, preferably radar sensors, each of which detects an angle of 360 °.

In particular, the common evaluation device determines an occupancy of the parking spaces by means of the data transmitted by the radar sensors. In this aspect, it is considered to be particularly advantageous if the loading park has at least one optical display for displaying the unoccupied parking spaces, in particular for displaying an empty parking space nearest the position of the respective display.

Preferably, the common evaluation device detects from the transmitted data a number of vehicles taken into the charging park and / or a number of vehicles which have been extended from the charging park and / or a number of vehicles located in the charging park. In particular, the common evaluation device detects the corresponding number of times.

Preferably, the common evaluation device determines from the transmitted data a number of vehicles located in the charging park, which are not parked on the parking spaces.

In the charging park according to the invention for charging electrically driven vehicles, In particular for carrying out the method according to the invention together with its further developments, it is provided that the loading park has several parking spaces for electrically driven vehicles, wherein the respective parking space is assigned a loading device for charging the parked on the respective parking space vehicle, further at least one radar sensor for detecting a position one or more vehicles located in the charging park, wherein the charging park has an evaluation device for evaluating the data detected by the at least one radar sensor.

In the charging park, the charging device can be designed differently. It is considered to be particularly advantageous if the charging device is designed as a charging station, wherein the charging station has a conductive charging system. Alternatively, the charging device may well be inductive, as discussed in the above-mentioned prior art document. In particular, a radar sensor is arranged in each charging station.

Further features of the invention will become apparent from the dependent claims, the accompanying drawings and the description of the reproduced in the drawing embodiment, without being limited thereto.
