Description

POSITIONSBESTIMMUNGSSYSTEM FÜR FAHRZEUGE MIT ELEKTRISCHEM ANTRIEB UND INDUKTIVER LADUNG  POSITION DETERMINATION SYSTEM FOR VEHICLES WITH ELECTRIC DRIVE AND INDUCTIVE CHARGING
Die vorliegende Erfindung betrifft ein Positionsbestimmungssystem für ein Fahrzeug (1), welches mittels eines induktiven Energieübertragungssystems (2, 4) aufladbar ist, wobei am Fahrzeug (1) eine sekundärseitige Energieübertragungsvorrichtung (2) und stationär eine primärseitige Energieübertragungsvorrichtung (4), insbesondere in Form eines Ladepunktes (4), angeordnet sind, welche zum Aufladen des Fahrzeuges (1) relativ zueinander in Position gebracht werden müssen, wobei stationär und/oder am Fahrzeug (1) zusätzliche Spulen und/oder Antennen angeordnet sind . The present invention relates to a position determining system for a vehicle (1) which can be charged by means of an inductive energy transmission system (2, 4), wherein on the vehicle (1) a secondary-side energy transmission device (2) and stationary primary energy transfer device (4), in particular in shape a charging point (4) are arranged, which must be brought into position for charging the vehicle (1) relative to each other, wherein stationary and / or on the vehicle (1) additional coils and / or antennas are arranged.
Fahrzeuge, die mittels induktiver Energieübertragungssysteme, also kabellos, geladen werden, verfügen über eine Pickup, welche relativ zu einer stationär- seitig angeordneten Energieübertragungsvorrichtung positioniert werden muss, damit eine induktive Energieübertragung mit gutem Wirkungsgrad möglich ist. So ist es bekannt, dass die primärseitige Energieübertragungsvorrichtung, welche primärseitig mindestens eine Spule aufweist, zu einem geparkten Fahrzeug mittels Aktuatoren verstellt und in Position gebracht wird. Auch ist es bekannt, dass die Pickup vom Fahrzeug abgesenkt und damit der primärseiti- gen Vorrichtung angenähert wird, so dass sich ein möglichst kleiner Luftspalt zwischen primärseitiger und sekundärseitiger Vorrichtung ergibt. Vehicles that are charged by means of inductive energy transmission systems, ie wireless, have a pickup, which must be positioned relative to a stationarily arranged side energy transfer device, so that an inductive energy transfer with good efficiency is possible. It is thus known that the primary-side energy transmission device, which has at least one coil on the primary side, is adjusted to a parked vehicle by means of actuators and brought into position. It is also known that the pickup is lowered from the vehicle and thus approximated to the device on the primary side, so that the smallest possible air gap results between the primary-side and the secondary-side device.
Ferner sind Positionierungshilfen bekannt, welche dem Fahrer optisch und/oder akustisch anzeigen ob und wie er die optimale Position erreichen kann bzw. wann er sie erreicht hat. Diese Positionierungshilfen bedienen sich meist zusätzlich am Fahrzeug oder stationär angeordneter Sender und Empfänger. Die WO 2011/116874 beschreibt ein System zur berührungslosen Energieübertragung an ein Fahrzeug, bei dem zusätzliche Spulen am Fahrzeug und/oder stationär um die jeweiligen Ladespulen angeordnet sind, mit denen das magnetische Feld der Energieübertragungsspulen detektierbar sind, wodurch eine Positionsbestimmung vom Fahrzeug relativ zum primärseitigen Ladepunkt des Energieübertragungssystems möglich ist. Nachteilig bei diesem System ist, der komplizierte Aufbau und die Tatsache, dass sich das Fahrzeug bereits in unmittelbarer Nähe zum Ladepunkt befinden muss, damit eine Positionsbestimmung hinreichend genau durchführbar ist. Furthermore, positioning aids are known which optically and / or acoustically indicate to the driver and how he can reach the optimum position or when he has reached it. These positioning aids usually use in addition to the vehicle or stationarily arranged transmitter and receiver. WO 2011/116874 describes a system for contactless energy transmission to a vehicle, in which additional coils are arranged on the vehicle and / or stationary around the respective charging coils, with which the magnetic field of the energy transmission coils can be detected, whereby a position determination of the vehicle relative to the primary side Charging point of the power transmission system is possible. A disadvantage of this system, the complicated structure and the fact that the vehicle must already be in close proximity to the charging point, so that a position determination is sufficiently accurate feasible.
Aufgabe der vorliegenden Erfindung ist es, ein in seinem Aufbau einfaches Positionbestimmungssystem bereitzustellen. Object of the present invention is to provide a simple in its construction position determination system.
Diese Aufgabe wird erfinderisch mit einem Positionbestimmungssystem mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen des Positionbestimmungssystems nach Anspruch 1 ergeben sich durch die Merkmale der Unteransprüche. This object is inventively achieved with a positioning system having the features of claim 1. Advantageous embodiments of the positioning system according to claim 1 result from the features of the subclaims.
Die relative Positionierung des Fahrzeuges über einem induktiven stationären Ladepunkt muss im Zentimeter-Bereich liegen, damit eine effiziente Energieübertragung erfolgen kann. Das erfindungsgemäße Positionbestimmungssystem kann zur Anzeige der aktuellen Position des Fahrzeuges bzw. der sekun- där-Ladeeinheit (Pickup) relativ zum Ladepunkt dienen und hilft somit dem Fahrer, das Fahrzeug an seine Ziel-Position zu bringen. Auch können die Daten des Positionbestimmungssystems für einen automatischen Parkassistenten verwendet werden, welcher das Fahrzeug möglichst optimal zu stationären Energieübertragungsvorrichtung bzw. des Ladepunktes einzuparken hilft oder selbsttätig einparkt. Dabei kann sich die Positionierungsvorrichtung vorteilhaft bereits am Fahrzeug angeordneter Sender und/oder Empfänger des schlüssellosen Zugangs- und Startsystems bedienen, welches bevorzugt magnetische bzw. elektromagnetische Sensoren verwendet. The relative positioning of the vehicle over an inductive stationary charging point must be in the centimeter range, so that an efficient energy transfer can take place. The positioning system according to the invention can be used to display the current position of the vehicle or the secondary charging unit (pickup) relative to the charging point and thus helps the driver to bring the vehicle to its destination position. Also, the data of the position determination system can be used for an automatic parking assistant, which helps the vehicle park as optimally as possible to stationary energy transmission device or the charging point or automatically parked. In this case, the positioning device can advantageously use already arranged on the vehicle transmitter and / or receiver of the keyless entry and start system, which preferably uses magnetic or electromagnetic sensors.
Sofern nur ein Sender und mindestens zwei Empfänger verwendet werden, kann der Sender in einer ersten Ausbildung der Erfindung stationär, insbesondere in unmittelbarer Nähe zum primärseitigen Ladepunkt des Energieübertragungssystems, oder in einer zweiten Ausbildung der Erfindung am Fahrzeug angeordnet werden. In der ersten Ausbildung der Erfindung müssen dann die Empfänger am Fahrzeug und in der zweiten Ausbildung stationär angeordnet werden. Die Empfänger sind dabei möglichst weit voneinander entfernt zu positionieren, damit sich eine gute Auflösung für das Positionsbestimmungssystem erzielen lässt. Entsprechendes gilt, sofern nur ein Empfänger und mehrere Sender vorgesehen werden. If only one transmitter and at least two receivers are used, the transmitter in a first embodiment of the invention may be stationary, in particular in the immediate vicinity of the primary-side charging point of the energy transmission system, or in a second embodiment of the invention on the vehicle to be ordered. In the first embodiment of the invention then the receivers on the vehicle and in the second embodiment must be arranged stationary. The receivers should be positioned as far apart as possible so that a good resolution can be achieved for the positioning system. The same applies if only one receiver and several transmitters are provided.
So können die am Fahrzeug angeordneten Empfänger bzw. Sender möglichst an den beiden Längsseiten des Fahrzeuges, insbesondere in den Türen, Türgriffen, den Türschwellern, am Fahrzeugboden oder an der Heckklappe oder dem Heckklappengriff angeordnet werden. Thus, the receiver or transmitter arranged on the vehicle can be arranged as possible on the two longitudinal sides of the vehicle, in particular in the doors, door handles, the door sills, on the vehicle floor or on the tailgate or the tailgate handle.
Selbstverständlich ist es auch möglich, dass das Positionsbestimmungssystem mindestens zwei Sender und mindestens zwei Empfänger aufweist, welche jeweils stationärseitig und am Fahrzeug angeordnet werden. Of course, it is also possible that the position determination system has at least two transmitters and at least two receivers, which are each arranged on the stationary side and on the vehicle.
Bei bereits bestehenden Zugangs- und Startsystemen, die meist auch Keyless- Entry Systeme genannt werden, wie z. B. das System KESSY® von der Firma Hella, sind Sendespulen am Fahrzeug, meist in der Nähe des Türgriffs oder in dem Türgriff angeordnet. Auch ist es möglich, die Sendespulen im Bereich der Türschweiler oder am Unterboden anzuordnen. Auch können sowohl im Türgriff als auch im Türschweiler und/oder am Unterboden relativ nahe an den Seiten des Fahrzeugs die Sendespulen angeordnet werden. Sofern das Positionbestimmungssystem den Abstand der am Fahrzeug angeordneten Sendespulen zueinander kennt, kann es aufgrund der am Ladepunkt gemessenen Signalstärken und/oder Laufzeitunterschiede der Signale den Abstand und die relative Ausrichtung des Fahrzeugs bzw. dessen Pickup zum Ladepunkt bestimmen. Diese Daten können von dem Fahrzeug für weitere Funktionen, z. B. für das automatische Einparken des Fahrzeugs dienen. Da die Sendespulen der Keyless-Entry Systeme aufgrund der Fahrzeugbreite ca. 1,5m voneinander entfernt sind, ergeben sich gut ermittelbare Unterschiede in den Signalstärken und/oder Signallaufzeiten der von den Sendespulen des Keyless-Entry Systems ausgesendeten Signale. For existing access and start systems, which are usually also called keyless entry systems, such. As the system KESSY® from Hella, transmission coils are arranged on the vehicle, usually in the vicinity of the door handle or in the door handle. It is also possible to arrange the transmitting coils in the area of the Türschweiler or on the underbody. Also, both in the door handle and in the Türschweiler and / or on the underbody relatively close to the sides of the vehicle, the transmission coils are arranged. If the positioning system knows the distance between the transmitter coils arranged on the vehicle, it can determine the distance and the relative orientation of the vehicle or its pickup to the charging point on the basis of the signal strengths and / or propagation time differences of the signals measured at the charging point. This data may be provided by the vehicle for additional functions, e.g. B. for the automatic parking of the vehicle. Since the transmission coils of the keyless entry systems are approximately 1.5 m apart due to the vehicle width, well-ascertainable differences in the signal strengths and / or signal propagation times of the signals emitted by the transmission coils of the keyless entry system result.
Selbstverständlich ist es möglich, dass die am Fahrzeug angeordneten Spulen des Keyless-Entry Systems als Empfangsspulen verwendet werden, welche Signale eines stationär angeordneten Senders empfangen. Auch bei dieser Ausführungsform können die ermittelten Unterschiede der gemessenen Signalstärken oder Signallaufzeiten zur Positionsbestimmung bzw. der relativen Lage von stationärem Ladepunkt und sekundärer Pickup verwendet werden. In diesem Fall ist der Sender des Positionsbestimmungssystems stationär und die Auswerteelektronik der Positionierungsvorrichtung auf dem Fahrzeug angeordnet. Of course, it is possible that the arranged on the vehicle coils of the keyless entry system are used as receiving coils, which Receive signals from a stationarily arranged transmitter. In this embodiment too, the determined differences in the measured signal strengths or signal propagation times for determining the position or the relative position of the stationary charging point and the secondary pickup can be used. In this case, the transmitter of the positioning system is stationary and the evaluation of the positioning device arranged on the vehicle.
Sofern der die Signallaufzeitunterschiede und/oder Signalstärkenunterschiede ermittelnde Empfänger stationärseitig angeordnet ist, kann das Positionsbestimmungssystem vollständig stationär angeordnet sein, wobei mittels einer stationärseitig und/oder im Fahrzeug angeordneten Anzeige dem Fahrer verschiedene Daten anzeigbar sind. Sofern eine Anzeige im Fahrzeug angeordnet ist, müssen die Positionsdaten dem Fahrzeug übermittelt werden. Sofern die Daten des Positionsbestimmungssystems einem automatischen Parkassistenten dienen sollen, müssen diese ebenfalls an das Fahrzeug übermittelt werden. If the receiver determining the signal propagation time differences and / or signal strength differences is arranged stationarily, the position determination system can be arranged completely stationary, whereby different data can be displayed to the driver by means of a display arranged on the stationary side and / or in the vehicle. If an advertisement is arranged in the vehicle, the position data must be transmitted to the vehicle. If the data of the positioning system are to serve an automatic parking assistant, they must also be transmitted to the vehicle.
In jedem Fall muss das Positionsbestimmungssystem Kenntnis von dem Fahrzeugtyp, der Anordnung der Pickup am Fahrzeug und die relative Lage der Sender und/oder Empfänger des Zugangs- und Startsystems haben, damit aus den Signaldaten zumindest der Abstand des Fahrzeugs zum Ladepunkt berechnet werden kann. So ist es im Sinne der Erfindung, wenn die Daten einmalig in die Positionierungsvorrichtung eingegeben werden. Gleichwohl ist es auch im Sinne der Erfindung, wenn die benötigten Daten vom Fahrzeug an das Positionsbestimmungssystem übermittelt werden, sofern diese nicht im Fahrzeug angeordnet ist. Auch kann das Positionsbestimmungssystem auf eine Datenbank zugreifen oder diese in einem Speicher des Systems abgespeichert sein, wobei in der Datenbank die entsprechenden Daten für den jeweiligen Fahrzeugtyp gespeichert sind, und das Fahrzeug beim Annähern an den Ladepunkt lediglich seinen Fahrzeugtyp an das Positionsbestimmungssystem übermittelt. Die Daten können dabei über das Zugangs- und Startsystem, ein separates Kommunikationssystem oder über die Datenübertragungsschnittstelle des induktiven Energieübertragungssystems übermittelt werden. Nachfolgend werden anhand von Zeichnungen zwei mögliche Ausführungsformen der Erfindung näher erläutert. In any case, the positioning system must have knowledge of the type of vehicle, the arrangement of the pickup on the vehicle and the relative position of the transmitter and / or receiver of the access and start system, so that from the signal data at least the distance of the vehicle to the charging point can be calculated. So it is within the meaning of the invention, when the data is entered once in the positioning device. However, it is also within the meaning of the invention, when the required data is transmitted from the vehicle to the positioning system, if it is not arranged in the vehicle. The positioning system can also access a database or store it in a memory of the system, the corresponding data for the respective vehicle type being stored in the database, and the vehicle merely transmitting its vehicle type to the positioning system as it approaches the charging point. The data can be transmitted via the access and start system, a separate communication system or via the data transmission interface of the inductive energy transmission system. Two possible embodiments of the invention will be explained in more detail with reference to drawings.

Meist ist die Ausrichtung FR des Fahrzeugs 1 durch die Parksituation, z. B. in einer Garage, vorbestimmt, so dass die allein von zwei Empfangsspulen 3a, 3b ermittelten Daten ausreichen, um dem Fahrer Kommandos, z.

Es ist selbstverständlich möglich, dass das erfindungsgemäße Positionsbestimmungssystem Fahrzeugdaten, wie z.B. Fahrzeuggeschwindigkeit, - beschleunigung, Lenkradeinschlag, etc., bei der Berechnung der Ausgabedaten des Systems verwendet. Die Figur 2 zeigt ein Positionsbestimmungssystem, bei dem die Sendespulen 3a, 3b, z.B. die des fahrzeugseitigen Zugangs- und Startsystems, Signale Sa und Sb aussenden, welche von dem stationärseitig angeordneten Empfänger 3c empfangen und ausgewertet werden. Die vom Empfänger 3c empfangenen Signale werden ausgewertet und von der entweder stationärseitig angeordneten Auswerteeinheit des Positionsbestimmungssystems ausgewertet oder aber an das im Fahrzeug 1 angeordnete Positionsbestimmungssystem übermittelt. It is of course possible that the position determination system according to the invention vehicle data, such as vehicle speed, - acceleration, steering angle, etc., in the calculation of the output data used by the system. FIG. 2 shows a position determination system in which the transmitting coils 3a, 3b, for example those of the vehicle-side access and starting system, emit signals S a and S b which are received and evaluated by the receiver 3c arranged on the stationary side. The signals received by the receiver 3c are evaluated and evaluated by the evaluation unit of the position-determining system arranged either on the stationary side or transmitted to the position-determining system arranged in the vehicle 1.
Selbstverständlich ist es auch möglich zwei Sender und zwei Empfänger zu verwenden, wodurch das System in der Lage wäre, allein aufgrund der Messung zu einem Zeitpunkt die Position und Ausrichtung des Fahrzeuges im Raum exakt zu bestimmen.. Of course, it is also possible to use two transmitters and two receivers, which would allow the system to accurately determine the position and orientation of the vehicle in space, solely on the basis of the measurement at a time.
