Description
Die Erfindung betrifft ein Fahrzeug mit einem Elektro-Antriebsmotor und einem elektrischen Energiespeicher als E-Fahrzeug oder Hybrid-Fahrzeug nach dem Oberbegriff des Anspruchs 1.The invention relates to a vehicle having an electric drive motor and an electrical energy store as an electric vehicle or hybrid vehicle according to the preamble of claim 1.
E-Fahrzeuge oder Hybridfahrzeuge, insbesondere als Personenkraftwagen mit Rädern und Reifen sind allgemein bekannt. Die elektrischen Energiespeicher solcher Fahrzeuge werden in allgemein bekannter Weise mit Ladekabeln an Steckdosen oder an Ladestationen induktiv und kabellos geladen. Zudem weisen solche Fahrzeuge entsprechend einer Tankanzeige eine Vorrichtung zur Ladezustandsanzeige des elektrischen Energiespeichers auf. Ein Zeigerinstrument oder Display der Ladezustandsanzeige ist dazu üblicherweise im Blickfeld eines Fahrers an der Schalttafel angeordnet und direkt oder indirekt über Kabel am elektrischen Energiespeicher angeschlossen.E-vehicles or hybrid vehicles, especially as passenger cars with wheels and tires are well known. The electrical energy storage such vehicles are charged in a well-known manner with charging cables to sockets or charging stations inductively and wirelessly. In addition, such vehicles according to a fuel gauge on a device for charging state display of the electrical energy storage. A pointer instrument or display of the charge status indicator is usually arranged in the field of vision of a driver on the control panel and connected directly or indirectly via cable to the electrical energy storage.
Der Ladezustand des elektrischen Energiespeichers kann mit einer solchen Ladezustandsanzeige von außerhalb und in einem Abstand zum Fahrzeug nicht erkannt werden. Insbesondere kann damit aus einer Entfernung der Ladezustand nicht erkannt werden, wenn ein solches Fahrzeug für einen Ladevorgang in einer Ladestation geparkt ist.The state of charge of the electrical energy storage can not be detected with such a charge status display from outside and at a distance from the vehicle. In particular, it can not be detected from a distance, the state of charge when such a vehicle is parked for a charge in a charging station.
Weiter ist eine Reifen-Profil-Verschleißanzeige bekannt (
Zudem ist eine Reifenheizung bekannt, bei der in einem Reifen ein Heizdraht integriert ist, wobei ein solches Heizelement durch Induktion mittels einer in der Nähe eines Reifens am Fahrzeug angebrachte Induktionsspule berührungslos mit Heizenergie versorgt werden kann.In addition, a tire heater is known, in which a heating wire is integrated in a tire, wherein such a heating element can be supplied by induction by means of an attached near a tire on the vehicle induction coil contactless with heating energy.
Weiter ist eine Leuchtanzeige mit einem Schriftzug oder Logo an einer Reifenseitenwand eines Fahrzeugs bekannt, die auch bei einem drehenden Reifen, das heißt bei einem vorbeifahrenden Fahrzeug, für einen stationären Beobachten als Standbild deutlich erkennbar oder lesbar sein soll. Dazu besteht die Leuchtanzeige aus einer Vielzahl von einzeln ansteuerbaren Leuchtelementen, die gesteuert insbesondere zu einem Schriftzug oder einem Logo kombiniert werden können. In der Steuerung wird eine erfasste Drehzahl des Reifens so berücksichtigt, dass in schneller Folge die Leuchtelemente dergestalt angesteuert werden, dass ein stationäres, nicht mit dem Reifen mitdrehendes Bild entsteht. Die Steuereinheit und ein Akku sind im Reifen bzw. einer Felge integriert und die erforderliche Betriebsenergie wird durch eine nicht näher beschriebene Umwandlung von Bewegungsenergie des Reifens erhalten.Further, a light display with a logo or logo on a tire sidewall of a vehicle is known, which should also be clearly recognizable or readable for a stationary tire, that is, in a passing vehicle, for stationary observation as a still image. For this purpose, the illuminated display consists of a plurality of individually controllable lighting elements, which can be combined in particular to a lettering or a logo controlled. In the control, a detected rotational speed of the tire is taken into account in such a way that the lighting elements are controlled in rapid succession in such a way that a stationary image not co-rotating with the tire is produced. The control unit and a battery are integrated in the tire or a rim and the required operating energy is obtained by an unspecified conversion of kinetic energy of the tire.
Aufgabe der Erfindung ist es, ein gattungsgemäßes Fahrzeug mit einem Elektro-Antriebsmotor und einem elektrischen Energiespeicher so weiterzubilden, dass dessen Ladezustand einfach von außerhalb des Fahrzeugs, insbesondere in Verbindung mit einem Ladevorgang an/in einer Ladestation ersichtlich und feststellbar ist.The object of the invention is to develop a generic vehicle with an electric drive motor and an electrical energy storage so that its state of charge is easily visible and detectable from outside the vehicle, especially in connection with a charging on / in a charging station.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of claim 1. Preferred embodiments of the invention are disclosed in the subclaims.
Diese Aufgabe wird dadurch gelöst, dass die Vorrichtung zur Ladezustandsanzeige wenigstens eine in eine Reifenwand, insbesondere eine Reifenseitenwand wenigstens eines Reifens eingelassene, steuerbare LED/OLED-Leuchtleiste oder eine sonstige optische Anzeige aufweist. Diese LED/OLED-Leuchtleiste ist reifenseitig einer Induktionsspule zugeordnet und die Energieversorgung der LED/OLED-Leuchtleiste und einer zugeordneten Steuereinheit erfolgt mittels Induktion. Zudem weist die Vorrichtung zur Ladezustandsanzeige eine drahtlose Kommunikationseinheit mit einer fahrzeugaufbauseitigen Teileinrichtung und einer zugeordneten reifenseitigen Teileinrichtung auf. Die aufbauseitige Teileinrichtung sendet einen erfassten Ladezustandswert des Energiespeichers jeweils an die reifenseitige Teileinrichtung, die mittels der Steuereinheit die LED/OLED-Leuchtleiste entsprechend einem aktuellen Ladezustand für einen zugeordneten visuellen Eindruck ansteuert.This object is achieved in that the device for charging state display at least one embedded in a tire wall, in particular a tire sidewall of at least one tire, controllable LED / OLED light bar or other optical display. This LED / OLED light bar is assigned to an induction coil on the tire side, and the power supply of the LED / OLED light bar and an associated control unit takes place by means of induction. In addition, the device for charging state display on a wireless communication unit with a vehicle body-side sub-device and an associated tire-side sub-device. The body-side part device sends a detected state of charge value of the energy store respectively to the tire-side subdevice, which controls the LED / OLED light bar in accordance with a current charge state for an associated visual impression by means of the control unit.
Damit kann vorteilhaft bereits in einem Abstand von außerhalb des Fahrzeugs der Ladezustand des elektrischen Energiespeichers an der Reifenanzeige abgelesen und erkannt werden. Dies ist besonders vorteilhaft in Verbindung mit einem Ladevorgang in/an einer Ladestation dergestalt, das ein Fahrer bereits bei der Annäherung an ein Fahrzeug erkennen kann, wie weit der Ladevorgang fortgeschritten ist oder gegebenenfalls bereits mit einem vollen Energiespeicher abgeschlossen ist. Eine entsprechende Information kann je nach Ausgestaltung der Leuchtleiste vorteilhaft schon von weitem gut sichtbar sein.This can be advantageously read and recognized at a distance from outside the vehicle, the state of charge of the electrical energy storage on the tire indicator. This is particularly advantageous in connection with a charging process in / at a charging station in such a way that a driver can already recognize when approaching a vehicle, how far the charging process has progressed or possibly already completed with a full energy storage. Depending on the design of the light strip, corresponding information can already be readily visible from a distance.
Vorteilhaft erfolgt die Energieversorgung der LED/OLED-Leuchtleiste und einer zugeordneten Steuereinheit drahtlos mittels Induktion, wobei die reifenseitige Induktionsspule und/oder die reifenseitige Teileinheit der Kommunikationseinrichtung weitgehend miniaturisiert in einer Reifenseitenwand integriert oder an der Felge angeordnet sein kann.Advantageously, the energy supply of the LED / OLED light bar and an associated control unit takes place wirelessly by means of induction, wherein the tire side induction coil and / or the tire side subunit of the communication device largely miniaturized integrated in a tire sidewall or can be arranged on the rim.
Es sind E-Fahrzeuge oder Hybrid-Fahrzeuge bekannt, die für ein induktives, stationäres Laden des elektrischen Energiespeichers in einer Ladestation ausgebildet sind. Dazu ist in der Ladestation wenigstens eine Primärspule bodenseitig ortsfest angeordnet, über der das Fahrzeug mit einer aufbauseitigen Sekundärspule für den Ladevorgang abgestellt wird. Ähnlich können auch reifenseitige Induktionsspulen als Sekundärspulen für die erfindungsgemäße Ladezustandsanzeige mit zugeordneten ortsfesten Primärspulen der Ladestation zusammenwirken. Gegebenenfalls kann auch das Feld der für die Ladung des Energiespeichers vorgesehenen ortsfesten Primärspule der Ladestation für eine induktive Energieversorgung der reifenseitigen Ladezustandsanzeige/n verwendet werden. Alternativ können stationäre Primärspulen im Bereich der Aufstandsflächen der Reifen vorgesehen sein. Ohne zusätzliche Maßnahmen, beispielsweise durch einen zusätzlich induktiv aufladbaren reifenseitigen Stützakku erlischt hier die Ladezustandsanzeige, wenn die ortsfeste/n Primärspule/n nicht mehr aktiviert sind und/oder das Fahrzeug die Ladestation verlässt.There are known electric vehicles or hybrid vehicles, which are designed for an inductive, stationary charging of the electrical energy storage in a charging station. For this purpose, at least one primary coil is arranged on the bottom side stationary in the charging station, over which the vehicle is parked with a body-side secondary coil for charging. Similarly, tire side induction coils can cooperate as secondary coils for the state of charge indicator according to the invention with associated stationary primary coils of the charging station. Optionally, the field of the intended for the charge of the energy storage stationary primary coil of the charging station for an inductive power supply of the tire-side state of charge display / n can be used. Alternatively, stationary primary coils may be provided in the area of the footprints of the tires. Without additional measures, for example, by an additionally inductively rechargeable tire side support battery expires the charge status indicator when the stationary / n primary coil / s are no longer activated and / or the vehicle leaves the charging station.
Weiter ist es allgemein bekannt einen elektrischen Energiespeicher eines E-Fahrzeugs oder gegebenenfalls auch eines Hybrid-Fahrzeugs an einer Ladestation mit einem Ladekabel aufzuladen. Insbesondere bei einem so ausgelegten Fahrzeug wird vorgeschlagen, dass die jeweils reifenseitige Induktionsspule als Sekundärspule mit einer zugeordneten fahrzeugaufbauseitigen Primärspule zusammenwirkt, welche mit dem elektrischen Energiespeicher gespeist wird. Auch ein induktiv aufladbarer elektrischer Energiespeicher kann entsprechend eingesetzt werden. Damit kann die Anzeigefunktion der Ladezustandsanzeige bis zur Entleerung des elektrischen Energiespeichers aufrechterhalten werden.Furthermore, it is generally known to charge an electrical energy store of an electric vehicle or possibly also of a hybrid vehicle at a charging station with a charging cable. In particular, in such a designed vehicle is proposed that the respective tire side induction coil cooperates as a secondary coil with an associated vehicle body-side primary coil, which is fed with the electrical energy storage. An inductively rechargeable electrical energy store can also be used accordingly. Thus, the display function of the charge status indicator can be maintained until the emptying of the electrical energy storage.
In einer weiterführenden Ausgestaltung kann zusätzlich oder gegebenenfalls alternierend weiter zum Ladezustand des elektrischen Energiespeichers wenigstens eine reifenseitig sensorerfasste Zustandsgröße insbesondere ein Reifenprofilzustand und/oder ein Reifenverschleiß mittels der LED/OLED-Leuchtanzeige angezeigt werden. Die Energieversorgung dazu kann entsprechend der Ladezustandsanzeige erfolgen.In a further embodiment, in addition or optionally alternately further to the state of charge of the electrical energy storage at least one tire-side sensor-detected state variable in particular tire profile state and / or tire wear by means of the LED / OLED indicator light can be displayed. The power supply can be done according to the charge status display.
Die Kommunikationseinheit kann zudem bidirektional aufgebaut sein, so die gegebenenfalls reifenseitig mittels Sensoren erfasste Zustandsgrößen, insbesondere ein Reifenprofilzustand und/oder ein Reifendruck auch drahtlos in den Fahrzeuginnenraum für eine Anzeige übertragbar sind.In addition, the communication unit can be of bidirectional design, so that the state variables, possibly detected on the tire side by means of sensors, in particular a tire profile state and / or a tire pressure, can also be transmitted wirelessly into the vehicle interior for display.
Der visuelle Eindruck für eine Informationswiedergabe durch die LED/OLED-Leuchtleiste kann unterschiedlich hergestellt werden: In einer bevorzugten Ausführungsform wird die LED/OLED-Leuchtleiste als an der Reifenseitenwand umlaufendes Leuchtband ausgebildet und ein unterschiedlicher Ladezustand des elektrischen Energiespeichers wird durch unterschiedliche Farben und/oder unterschiedliche Leuchtstärken angezeigt. Bei einem entladenen Energiespeicher ist die LED/OLED-Leuchtleiste dunkel und geht beispielsweise mit ansteigender Leuchtstärke in die Farbe gelb bei etwa 50% Ladezustand über und wechselt dann allmählich zu einer grünen Farbe am Ende des Ladevorgangs bei 100% Ladezustand. Auch andere Informationsausgaben sind ersichtlich realisierbar: beispielsweise können mit fortschreitendem Ladezustand Teilsegmente des Leuchtbands aufleuchten, die sich dann größer werdend zu einem geschlossenen Leuchtbandkreis am Ende des Ladevorgangs ergänzen.The visual impression for an information reproduction by the LED / OLED light bar can be produced differently: In a preferred embodiment, the LED / OLED light bar is designed as a light strip circulating on the tire sidewall and a different state of charge of the electrical energy store by different colors and / or different brightness levels are displayed. When the energy store is discharged, the LED / OLED light bar is dark and turns yellow, for example, with increasing light intensity at about 50% charge status and then gradually changes to a green color at the end of the charging process at 100% charge level. Other information outputs can also be realized: for example, as the state of charge progresses, sub-segments of the illuminated strip light up, which then become larger in order to complete a closed light-circuit at the end of the charging process.
Alternativ, zusätzlich oder alternierend kann die LED/OLED-Leuchtleiste zumindest in Teilbereichen so ausgebildet und angeordnet sein, dass damit gesteuert, gegebenenfalls frei programmierbar ein Schriftzug oder ein Logo herstellbar ist. Beispielsweise kann die fertige Ladung mit 100% Ladezustand auch mittels einer Schriftzuginformation zum Beispiel „Ladung beendet” am Reifen angezeigt werden. Unabhängig von der Ladung eines Energiespeichers können gegebenenfalls auch Produktnahmen und/oder Logos von Reifen- und/oder Fahrzeugherstellern angezeigt werden.Alternatively, in addition or in alternation, the LED / OLED light strip can be designed and arranged at least in some areas in such a way that a lettering or a logo can be produced, optionally freely programmable. For example, the finished load with 100% state of charge can also be displayed on the tire by means of lettering information, for example "charge completed". Regardless of the charge of an energy storage, product and / or logo of tire and / or vehicle manufacturers may also be displayed as appropriate.
