Description
Die Erfindung betrifft ein Verfahren zum Erkennen des Ladezustands einer Fahrzeugbatterie eines Hybrid- oder Elektrofahrzeugs, wobei unterschiedliche optische Anzeigen eine Information über den Ladezustand der Fahrzeugbatterie geben.The invention relates to a method for detecting the state of charge of a vehicle battery of a hybrid or electric vehicle, wherein different visual displays provide information about the state of charge of the vehicle battery.
Bei Hybrid- oder Elektrofahrzeugen mit Plug-In Funktion besteht die Möglichkeit, das Fahrzeug zum Aufladen der Fahrzeugbatterie mit dem stationären Stromnetz zu verbinden. Dazu wird das Fahrzeug über ein Ladekabel mit einer stationären Ladesäule verbunden.In hybrid or electric vehicles with plug-in function, it is possible to connect the vehicle to the stationary power grid for charging the vehicle battery. For this purpose, the vehicle is connected via a charging cable to a stationary charging station.
Es ist bekannt, über einen Leuchtring an einer Ladedose der Ladesäule eine Rückmeldung über den Zustand der Ladung der Fahrzeugbatterie zu geben.It is known to give a feedback on the state of the charge of the vehicle battery via a light ring on a charging socket of the charging station.
Aus der
Aufgabe der Erfindung ist es, ein Verfahren der eingangs genannten Art so weiter zu bilden, dass es erlaubt, von außerhalb des Fahrzeugs, insbesondere in größerem Sichtweitenabstand vom Fahrzeug, den Ladezustand der Fahrzeugbatterie zu erkennen, insbesondere, wenn das Fahrzeug an eine Ladestation angeschlossen ist.The object of the invention is to form a method of the type mentioned so that it allows to detect the state of charge of the vehicle battery from outside the vehicle, in particular at a greater visibility distance from the vehicle, in particular when the vehicle is connected to a charging station ,
Gelöst wird die Aufgabe dadurch, dass eine Funkschlüssel gesteuerte, über einen bestimmten Zeitraum erfolgende Anzeige des Ladezustand über eine Beleuchtungsanlage des Fahrzeugs erfolgt. Dabei sollen als Funkschlüssel alle Bedienelemente bezeichnet werden, die eine Ansteuerung bzw. Auslösung von Fahrzeugfunktionen ohne Fahrzeugkontakt auf Entfernung ermöglichen, z. B. ein Zentralverriegelungs-Funkschlüssel oder ein Standheizungs-Bedienelement.The object is achieved in that a radio key controlled, over a certain period of time takes place display of the state of charge via a lighting system of the vehicle. It should be referred to as a radio key all controls that allow control or triggering of vehicle functions without vehicle contact at a distance, z. B. a central locking radio key or a parking heater control.
Gemäß der Erfindung gibt somit das Fahrzeug selbst die optische Information über den Ladezustand der Fahrzeugbatterie, nämlich über die Beleuchtungsanlage des Fahrzeugs. Hierbei wird über den Funkschlüssel des Fahrzeugs, der üblicherweise verwendet wird, um die Türen des Fahrzeugs zu öffnen und die Wegfahrsperre des Fahrzeugs zu deaktivieren sowie die Zündung des Fahrzeugs zu schalten, die Anzeige gesteuert, die die Information über den Ladezustand der Fahrzeugbatterie mittels der Beleuchtungsanlage des Fahrzeugs gibt. Die Anzeige gibt somit eine quantitative Information über den Ladezustand der Fahrzeugbatterie, insbesondere ob die Fahrzeugbatterie entladen ist, vollständig geladen ist oder teilweise geladen ist, wobei unterschiedliche Teilladezustände der Fahrzeugbatterie gleichfalls über die Beleuchtungsanlage ausgegeben werden können. Die unterschiedlichen optischen Anzeigen geben die quantitative Information über den Ladezustand der Fahrzeugbatterie.According to the invention, the vehicle itself thus gives the optical information about the state of charge of the vehicle battery, namely about the lighting system of the vehicle. Here, via the radio key of the vehicle, which is usually used to open the doors of the vehicle and disable the immobilizer of the vehicle and to switch the ignition of the vehicle, the display is controlled, the information about the state of charge of the vehicle battery by means of the lighting system of the vehicle. The display thus gives a quantitative information about the state of charge of the vehicle battery, in particular whether the vehicle battery is discharged, is fully charged or partially charged, with different partial load conditions of the vehicle battery can also be output via the lighting system. The different optical displays give the quantitative information about the state of charge of the vehicle battery.
Grundsätzlich kann diese optische Anzeige des Ladezustand der Fahrzeugbatterie auf unterschiedliche Art und Weise erfolgen. So kann die optische Anzeige mittels derselben Lichtquelle der Beleuchtungsanlage des Fahrzeugs erfolgen, wobei entsprechend der Änderung des Ladezustands eine geänderte Leuchtdauer oder Lichtintensität verwendet wird. Es wird aber als besonders vorteilhaft angesehen, wenn unterschiedliche Lichtquellen der Beleuchtungsanlage entsprechend dem Ladezustand der Fahrzeugbatterie beim Ansteuern über den Funkschlüssel geschaltet werden. Dies ermöglicht es, dem Fahrer bzw. der den Funkschlüssel benutzenden Person den Ladezustand der Fahrzeugbatterie besonders einfach zu erkennen. Insbesondere werden unterschiedliche Lichtquellen entsprechend dem Ladezustand der Fahrzeugbatterie nacheinander geschaltet oder zugeschaltet. Mit zunehmendem Ladezustand der Fahrzeugbatterie leuchten entweder andere Lichtquellen oder es erhöht sich die Anzahl der leuchtenden Lichtquellen der Beleuchtungsanlage.Basically, this optical indication of the state of charge of the vehicle battery can be done in different ways. Thus, the optical display can be carried out by means of the same light source of the lighting system of the vehicle, wherein according to the change in the state of charge, a changed lighting duration or light intensity is used. However, it is considered to be particularly advantageous if different light sources of the lighting system are switched in accordance with the state of charge of the vehicle battery when driving via the radio key. This makes it particularly easy for the driver or the person using the radio key to recognize the state of charge of the vehicle battery. In particular, different light sources are switched or connected in succession in accordance with the state of charge of the vehicle battery. With increasing state of charge of the vehicle battery light up either other light sources or it increases the number of luminous light sources of the lighting system.
Da gemäß dem erfindungsgemäßen Verfahren die Anzeige des Ladezustands per Funkschlüssel gesteuert wird, kann das erfindungsgemäße Verfahren bei einem Fahrzeug Verwendung finden, das zum Laden der Fahrzeugbatterie über ein Ladekabel mit einer stationären Ladesäule verbunden ist und demzufolge sich der Ladezustand der Fahrzeugbatterie über die Zeit ändert. Andererseits kann aufgrund der Funkschlüsselsteuerung auch zu jedem anderen beliebigen Zeitpunkt, somit dann, wenn die Fahrzeugbatterie nicht geladen wird, der Ladezustand der Fahrzeugbatterie von außerhalb des Fahrzeugs, in größerem Sichtweitenabstand zum Fahrzeug erkannt werden, beispielsweise, wenn das Fahrzeug auf einer Parkfläche in der Nähe einer Wohnung abgestellt ist und der Fahrer von der Wohnung aus sich darüber informieren möchte, welchen Ladezustand die Fahrzeugbatterie seines Fahrzeuges besitzt. Er kann dann an dem Aufleuchten der Beleuchtungsanlage des Fahrzeugs den Ladezustand der Fahrzeugbatterie von seiner Wohnung aus erkennen.Since according to the inventive method, the display of the state of charge is controlled by remote control key, the inventive method can be used in a vehicle that is connected to charge the vehicle battery via a charging cable with a stationary charging station and consequently changes the state of charge of the vehicle battery over time. On the other hand, due to the radio key control at any other arbitrary point in time, thus when the vehicle battery is not charged, the state of charge of the vehicle battery from outside the vehicle, be recognized at a greater visibility distance to the vehicle, for example, when the vehicle on a parking area in the vicinity an apartment is parked and the driver would like to inform from the apartment about which state of charge has the vehicle battery of his vehicle. He can then recognize the charging of the vehicle battery from his apartment at the lighting of the lighting system of the vehicle.
Vorzugsweise wird mittels der Nebelscheinwerfer und/oder der Hauptscheinwerfer und/oder des Standlichts des Fahrzeugs der Ladezustand der Fahrzeugbatterie optisch angezeigt. Grundsätzlich können auch weitere Lichtquellen geschaltet werden, beispielsweise Bremslicht, Blinker, Nebelschlussleuchte, Tagfahrlicht. Preferably, the state of charge of the vehicle battery is visually displayed by means of the fog lights and / or the headlight and / or the parking light of the vehicle. In principle, other light sources can be switched, for example, brake light, turn signal, rear fog light, daytime running lights.
Dabei sind unterschiedliche Szenarien denkbar, beispielsweise dass über Nebel-, Hauptscheinwerfer und Standlicht der Ladezustand signalisiert wird, und zwar durch Zuschalten der Lichtquellen, nämlich Einschalten von Nebelscheinwerfer
Bevorzugt werden Lichtquellen des Fahrzeuges vorne und/oder hinten am Fahrzeug geschaltet bzw. zugeschaltet. Insbesondere dann, wenn unterschiedliche Lichtquellen geschaltet bzw. zugeschaltet werden, reicht es völlig aus, wenn die Anzeige des Ladezustands kurzzeitig erfolgt. Eine längere Anzeige des Ladezustands ist aber durchaus im Rahmen des erfindungsgemäßen Verfahrens und berücksichtigt das Merkmal der Anzeige des Ladezustands über einen bestimmten Zeitraum.Preferably, light sources of the vehicle are switched or switched on at the front and / or at the rear of the vehicle. In particular, when different light sources are switched or switched on, it is completely sufficient if the display of the state of charge takes place for a short time. However, a longer indication of the state of charge is well within the scope of the method according to the invention and takes into account the feature of displaying the state of charge over a certain period of time.
Vorzugsweise erfolgt durch Betätigen einer Taste des Funkschlüssels des Fahrzeugs die Ansteuerung der optischen Anzeige. Die Komponenten der Beleuchtungsanlage des Fahrzeugs werden dabei, nach dem Betätigen der Taste auf dem Funkschlüssel des Fahrzeugs, für einen bestimmten Zeitraum aufgeblendet, und informieren den Fahrer so über den Ladezustand der Fahrzeugbatterie.Preferably, by pressing a button of the remote control key of the vehicle, the control of the visual display. The components of the lighting system of the vehicle are displayed, after pressing the button on the remote key of the vehicle, for a certain period of time, and inform the driver about the state of charge of the vehicle battery.
Die Ansteuerung der optischen Anzeige erfolgt vorzugsweise über die Aktivierungsdauer einer vorhandenen Taste, d. h. mittels Überstimmung einer Grundfunktion durch Halten der Taste, oder die Aktivierung einer zusätzlichen Taste des Funkschlüssels.The control of the optical display is preferably carried out over the activation period of an existing button, d. H. by overriding a basic function by holding the button, or activating an additional button of the remote control key.
Der Fahrer kann so, zum Beispiel auf einem Parkplatz, vom Fenster oder einem Balkon aus, den Ladezustand seines Fahrzeugs bei aktivem oder nicht aktivem Ladevorgang per Tastendruck jederzeit abrufen.The driver can thus, for example, in a parking lot, from the window or a balcony, the charge state of his vehicle with active or inactive charging at the touch of a button at any time.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen, der beigefügten Zeichnung und der Beschreibung des in der Zeichnung wiedergegebenen Ausführungsbeispiels, ohne auf dieses beschränkt zu sein.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.
