Description

Die Erfindung betrifft ein System zur induktiven Übertragung von Energie von einer Energieversorgungseinheit mit einer eine Primärspule aufweisenden beweglichen Bodeneinheit an ein einen zu ladenden Energiespeicher aufweisendes Fahrzeug, wobei die Energieversorgungseinheit ausgebildet ist, die Position der Bodeneinheit auf einem Fahrzeugstellplatz zu erkennen und eine Warnung anzuzeigen, wenn beim Positionieren einer Sekundärspule des Fahrzeugs über der Primärspule eine Kollisionsgefahr besteht.The invention relates to a system for the inductive transmission of energy from a power supply unit having a mobile unit having a primary coil to a vehicle to be charged energy storage, wherein the power supply unit is configured to detect the position of the ground unit on a vehicle parking space and to indicate a warning when when positioning a secondary coil of the vehicle over the primary coil there is a risk of collision.

Ein solches System ist aus der DE 10 2013 207 906 A1 bekannt. Die dortige als Ladestation bezeichnete Energieversorgungseinheit und ggf. das Fahrzeug sollen dort eingerichtet sein, eine Verschiebung der Bodeneinheit zu erkennen. Die Erkennung einer Verschiebung sollte auch dann funktionieren, wenn kein Fahrzeug geladen wird bzw. wenn kein Fahrzeug über der Primärspule steht. Der Fahrer kann nach einer Verschiebung der Bodeneinheit benachrichtigt werden und ggf. aufgefordert werden, eine Positionsüberprüfung durchzuführen.Such a system is out of the DE 10 2013 207 906 A1 known. The there designated as a charging station power supply unit and possibly the vehicle should be set up there to detect a shift of the ground unit. The detection of a shift should work even if no vehicle is loaded or if no vehicle is above the primary coil. The driver may be notified after a shift of the ground unit and may be requested to perform a position check.

Problematisch ist jedoch die Situation, wenn das Fahrzeug ausgebildet ist, sich selbständig über der Bodeneinheit zu positionieren, also einen Einparkassistenten aufweist und Signale über die aktuelle Position der Bodeneinheit erhält.The problem, however, is the situation when the vehicle is designed to position itself on the ground unit, that has a parking assistant and receives signals about the current position of the ground unit.

Wenn die Bodeneinheit verschoben wurde und nun nahe bei einem Hindernis steht, das eine Positionierung des Fahrzeugs oberhalb der Bodenplatte ohne Gefahr eines Schadens nicht ermöglicht, würde dies vom Fahrzeug möglicherweise nicht erkannt werden.If the ground unit has been moved and is now near an obstacle that does not allow the vehicle to be positioned above the floorboard without risk of damage, the vehicle might not recognize it.

Es ist daher die Aufgabe der Erfindung, ein System zur induktiven Übertragung von Energie von einer Energieversorgungseinheit an ein Fahrzeug anzugeben, das hier Abhilfe schafft.It is therefore an object of the invention to provide a system for the inductive transmission of energy from a power supply unit to a vehicle, which provides a remedy.

Die Aufgabe wird durch ein System gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.The object is achieved by a system according to claim 1. Advantageous developments are specified in the subclaims.

Demnach weist bei einem System zur induktiven Übertragung von Energie von einer Energieversorgungseinheit mit einer eine Primärspule aufweisenden beweglichen Bodeneinheit an ein einen zu ladenden Energiespeicher aufweisendes Fahrzeug, wobei die Energieversorgungseinheit ausgebildet ist, die Position der Bodeneinheit auf einem Fahrzeugstellplatz zu erkennen und eine Warnung anzuzeigen, wenn beim Positionieren einer Sekundärspule des Fahrzeugs über der Primärspule eine Kollisionsgefahr besteht, das Fahrzeug einen Einparkassistenten auf, welcher eingerichtet ist, aufgrund der Warnung ein selbständiges Positionieren zu unterlassen.Accordingly, in a system for inductive transmission of energy from a power supply unit having a movable coil having a primary coil to a vehicle to be charged energy storage, the power supply unit is configured to detect the position of the ground unit on a vehicle parking space and to indicate a warning when when a secondary coil of the vehicle is positioned above the primary coil, there is a risk of collision, the vehicle has a parking assistant, which is set up to refrain from autonomous positioning due to the warning.

Hierdurch kann wirksam verhindert werden, dass ein Fahrzeug oder ein sich im Bereich der Bodeneinheit befindlicher Gegenstand beschädigt wird, wenn sich die Bodeneinheit nicht an ihrem vorgesehenen, üblichen Ort befindet.This can effectively prevent a vehicle or an object located in the area of the ground unit from being damaged if the ground unit is not in its intended, usual location.

In einer vorteilhaften Weiterbildung ist der Einparkassistenten des erfindungsgemäßen Systems eingerichtet, ein Signal auszusenden, das anzeigt, dass eine Positionierung nicht möglich ist.In an advantageous development of the parking assistant of the system according to the invention is set up to send out a signal indicating that positioning is not possible.

Hierdurch wird verhindert, dass das Fahrzeug einfach stehen bleibt und daher nicht geladen werden kann, weil der Fahrer möglicherweise bereits weggegangen ist, da er nun eine Mitteilung beispielsweise durch ein akustisches oder optisches Signal oder auf ein mobiles Gerät, beispielsweise ein Smartphone, erhält, das ihm anzeigt, dass die Bodenplatte wieder richtig positioniert werden muss.This prevents the vehicle from simply stopping and therefore can not be charged because the driver may already have gone away, as he now receives a message, for example, by an audible or visual signal or to a mobile device, such as a smartphone It indicates that the bottom plate must be correctly positioned again.

Die Benachrichtigung kann dabei über übliche drahtlose Kommunikationsverbindungen wie WLAN, Bluetooth, Mobilfunk etc. erfolgen.The notification can be done via standard wireless communication links such as WLAN, Bluetooth, mobile, etc.

Die Erfindung soll nachfolgend anhand eines Ausführungsbeispiels mit Hilfe von Figuren näher erläutert werden. Dabei zeigt

  • 1 ein erfindungsgemäßes System zur induktiven Übertragung von Energie von einer Energieversorgungseinheit an ein Fahrzeug
The invention will be explained in more detail using an exemplary embodiment with the aid of figures. It shows
  • 1 a system according to the invention for the inductive transmission of energy from a power supply unit to a vehicle

Die 1 zeigt eine Energieversorgungseinheit 1 mit einer üblicherweise stationären Ladestation 2, häufig auch „wallbox“ genannt, die über ein Netzkabel 16 z.B. mit dem öffentlichen Wechselspannungsnetz verbunden ist.The 1 shows a power supply unit 1 with a usually stationary charging station 2 , often called "wallbox", which has a power cord 16 eg connected to the public alternating voltage network.

Die Ladestation 2 überträgt die darüber bezogene Energie nach einer entsprechenden Wandlung als hochfrequente Spannung über eine Energieversorgungsleitung 5 an eine Primärspule 4, die in einer Bodeneinheit 3 verbaut ist.The charging station 2 transmits the related energy after a corresponding conversion as a high-frequency voltage via a power supply line 5 to a primary coil 4 standing in a ground unit 3 is installed.

Die Bodeneinheit 3 ist als mobile Bodeneinheit beispielsweise als Bodenmatte ausgebildet und ist daher weder in den Boden eingelassen noch mit diesem verschraubt oder sonstwie befestigt.The ground unit 3 is designed as a mobile floor unit, for example, as a floor mat and is therefore neither embedded in the ground nor screwed with this or otherwise secured.

Die Bodeneinheit 3 ist außer über die Energieversorgungsleitung 5 auch noch über eine Kommunikationsleitung 6 mit der Ladestation 2 verbunden. Prinzipiell kann eine Kommunikation zwischen der Bodeneinheit 3 und der Ladestation 2 aber auch drahtlos stattfinden.The ground unit 3 is beyond the power supply line 5 also via a communication line 6 with the charging station 2 connected. In principle, a communication between the ground unit 3 and the charging station 2 but also take place wirelessly.

Die normale Position der Bodeneinheit 3 in Relation zur Ladestation 2 kann in der Energieversorgungseinheit 1 durch Anlernen festgelegt werden. Abweichungen davon können entweder durch geeignete Sensoren in der Bodeneinheit 3 oder in der Ladestation 2 beispielsweise mittels optischer Sensoren ermittelt werden.The normal position of the ground unit 3 in relation to the charging station 2 can in the Power supply unit 1 be determined by training. Deviations can be made either by suitable sensors in the ground unit 3 or in the charging station 2 be determined for example by means of optical sensors.

Die 1 zeigt außerdem ein Fahrzeug 10, das eine Sekundärspule 11 aufweist, die mit der Primärspule 4 der Bodeneinheit 3 im optimal positionierten Zustand einen gut gekoppelten Transformator zur induktiven Übertragung von Energie an das Fahrzeug 10 bildet.The 1 also shows a vehicle 10 that is a secondary coil 11 which is connected to the primary coil 4 the ground unit 3 in optimally positioned condition, a well-coupled transformer for inductive transmission of energy to the vehicle 10 forms.

Die von der Sekundärspule 11 aufgenommene Energie wird über einen Energiewandler 12, der insbesondere einen Gleichrichter aufweist, an einen Energiespeicher 13, zumeist in Form eines Akkumulators, übertragen und dort gespeichert, um für den Antrieb von Elektromotoren zur Verfügung zu stehen.The from the secondary coil 11 Energy absorbed is via an energy converter 12 , which in particular has a rectifier, to an energy store 13 , usually in the form of an accumulator, transmitted and stored there to be available for driving electric motors.

Das Fahrzeug 10 weist außerdem einen Einparkassistenten 14 auf, der es ermöglicht, dass das Fahrzeug 10 mit Hilfe von Sensoren und Aktoren selbstständig einen vorgegebenen Parkplatz auffindet und sich dort platziert.The vehicle 10 also has a parking assistant 14 on that makes it possible for the vehicle 10 with the help of sensors and actuators independently finds a given parking space and places itself there.

Bei einem solchen System zum induktiven Laden einer Fahrzeugbatterie 13 müssen die Primärspule 4 in der Bodeneinheit 3 und die Sekundärspule 11 im Fahrzeug räumlich zueinander in Position gebracht werden, um einen möglichst guten Kopplungsfaktor zu erzielen. Dabei kommuniziert die Bodeneinheit 3 mit dem Fahrzeug 10 gegebenenfalls über die Ladestation 2 und ein dort implementiertes Gerät zur drahtlosen Kommunikation 15, so dass das Fahrzeug 10 die Spulenposition kennt und selbstständig, wie es vom automatisierten Fahren bekannt ist, in die entsprechende Parkposition fährt und die fahrzeugseitige Sekundärspule 11 zur Primärspule 4 in der Bodeneinheit 3 mit der geforderten Positionsgenauigkeit in Deckung bringt.In such a system for inductively charging a vehicle battery 13 need the primary coil 4 in the ground unit 3 and the secondary coil 11 be spatially brought into position in the vehicle to achieve the best possible coupling factor. The ground unit communicates 3 with the vehicle 10 optionally via the charging station 2 and a wireless communication device implemented there 15 so that the vehicle 10 knows the coil position and independently, as it is known from automated driving, moves to the appropriate parking position and the vehicle-side secondary coil 11 to the primary coil 4 in the ground unit 3 coincides with the required positional accuracy.

Dabei wird normalerweise davon ausgegangen, dass die Bodeneinheit 3 in der zur Umgebung und Fahrzeug 10 angepassten Position verlegt ist. Die Bodeneinheit 3 kann in der Garage eines Eigenheims mobil, vergleichbar mit einer Bodenmatte, verlegt werden. Durch ein Verschieben der Bodeneinheit 3, z.B. durch spielende Kinder, Bodenreinigung etc. kann die von einem Fahrzeug einzunehmende Position verändert werden. Mögliche Folgen sind dabei eine falsche Position des Fahrzeugs 10 in der Garage, die Ladeposition wird nicht erreicht, weil das Fahrzeug ein anderes Hindernis erkennt und stehen bleibt, was zum Abbruch der automatischen Positionierung führt, oder gar eine Beschädigung des Fahrzeugs oder der Garagenwand oder eines Gegenstands.It is usually assumed that the ground unit 3 in the area and vehicle 10 adjusted position. The ground unit 3 Can be moved in the garage of a home mobile, comparable to a floor mat. By moving the ground unit 3 , eg by playing children, floor cleaning, etc. can be changed by a vehicle position to be changed. Possible consequences are an incorrect position of the vehicle 10 in the garage, the loading position is not reached because the vehicle recognizes another obstacle and stops, which leads to the termination of the automatic positioning, or even damage to the vehicle or the garage wall or an object.

Die Kommunikation der Primärspule 4 mit der Sekundärspule 11 kann mit verschiedenen bekannten Methoden technisch realisiert werden. Daher bietet es sich an, dass ein drahtloses Übertragungsverfahren - beispielsweise WLAN oder Bluetooth - genutzt wird, um die Position der Primärspule 4 zur Ladestation 2 (Wallbox) zu übermitteln. Eine Veränderung der Position der Bodeneinheit 3 zur Ladestation 2 kann somit erkannt und angezeigt werden.The communication of the primary coil 4 with the secondary coil 11 can be technically realized by various known methods. Therefore, it makes sense that a wireless transmission method - for example, WLAN or Bluetooth - is used to the position of the primary coil 4 to the charging station 2 (Wallbox). A change in the position of the ground unit 3 to the charging station 2 can thus be recognized and displayed.

Ein Versatz der Bodeneinheit 3 kann z.B. optisch oder akustisch von der Ladestation 2 angezeigt werden. Ein automatischer Positioniervorgang kann durch die Ladestation 2 unterbunden werden. Eine Fehlermeldung zum Fahrzeug 10, z.B. an ein Fahrerinformationssystem oder direkt an den Fahrer z.B. an dessen Smartphone kann den Fahrer darauf aufmerksam machen, dass kein Ladevorgang stattfinden kann.An offset of the ground unit 3 can eg visually or acoustically from the charging station 2 are displayed. An automatic positioning process can be performed by the charging station 2 be prevented. An error message about the vehicle 10 For example, to a driver information system or directly to the driver eg on the smartphone can alert the driver that no charging can take place.

Eine einmal angelernte Position der Primärspule 4 kann nach einem Versatz mit Hilfe der Warnung durch die Ladestation 2 leicht wieder eingerichtet werden.A once learned position of the primary coil 4 can after an offset with the help of the warning by the charging station 2 easily be set up again.
