Kraftfahrzeuge mit einer hybriden Antriebseinheit bestehend aus einer Brennkraftmaschine und einem Elektromotor benötigen einen elektrischen Speicher, in dem die Energie zum Betreiben des Elektromotors gespeichert wird. Derartige elektrische Speicher müssen eine große Speicherkapazität aufweisen, damit immer ausreichend Energie für den Betrieb des Elektromotors zur Verfügung steht.motor vehicles with a hybrid drive unit consisting of an internal combustion engine and need an electric motor an electrical storage in which the energy for operating the electric motor is stored. Such electrical storage must have a size memory have, thus always sufficient energy for the operation of the electric motor to disposal stands.
Derzeit sind elektrische Speicher bekannt, die während des Betriebs der Antriebseinheit des Kraftfahrzeugs derart temperiert werden müssen, dass eine ausreichende Lebensdauer des Speichers gewährleistet werden kann. Während eines längeren Fahrzeugstillstandes kann sich der Speicher soweit erwärmen bzw. abkühlen, dass der Arbeitstemperaturbereich des Speichers verlassen wird. Bei Fahrzeug-Start kann der Speicher nicht oder nicht mit voller Leistung belastet werden.Currently are known electrical storage during operation of the drive unit of the motor vehicle must be tempered so that a sufficient Life of the memory guaranteed can be. While a longer vehicle standstill the memory can warm up or cool down so far that the working temperature range of the memory is left. At vehicle start The memory may not load or not at full capacity become.
Aufgabe der Erfindung ist es, ein Verfahren anzugeben, welches eine Temperierung des elektrischen Speichers auch bei abgeschalteter Antriebseinheit ermöglicht.task The invention is to provide a method, which is a temperature the electrical storage even when the drive unit is switched off allows.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren nach Anspruch 1 und ein Kraftfahrzeug nach Anspruch 9 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Ansprüchen.These The object is achieved by a Method according to Claim 1 and a motor vehicle according to Claim 9 solved. Advantageous embodiments emerge from the dependent claims.
Der Erfindung liegt die Erkenntnis zugrunde, dass ein Temperieren eines elektrischen Speichers bei abgeschalteter Antriebseinheit nicht dauerhaft vorgenommen werden kann, da dazu sehr viel Energie benötigt werden würde. Da es wichtig ist, dass der elektrische Speicher zum Zeitpunkt, indem er Energie liefern soll, richtig temperiert ist, wird durch das erfindungsgemäße Verfahren vorgeschlagen, dass eine zum Temperieren des elektrischen Speichers vorgesehene Heiz- und/oder Kühleinheit bei abgeschalteter Antriebseinheit erst aktiviert wird, wenn ein Startwunsch des Fahrers zum Starten der Antriebseinheit erkennbar ist. Das erfindungsgemäße Kraftfahrzeug ist dementsprechend mit einer entsprechenden Heiz- und/oder Kühleinheit zum Temperieren eines elektrischen Speichers gemäß dem erfindungsgemäßen Verfahren ausgestattet.Of the Invention is based on the finding that a tempering of a electrical memory with switched off drive unit is not can be made permanently because it requires a lot of energy would. Since it is important that the electrical storage at the time by delivering energy, being properly tempered, is going through the inventive method proposed that one intended for tempering the electrical storage Heating and / or cooling unit is activated when the drive unit is switched off when a start request the driver is recognizable for starting the drive unit. The motor vehicle according to the invention is accordingly with a corresponding heating and / or cooling unit for tempering an electrical storage according to the inventive method fitted.
Das erfindungsgemäße Verfahren bietet den Vorteil, dass durch eine vermutlich nur kurzzeitige Temperierung des elektrischen Speichers bei abgeschalteter Antriebseinheit nur wenig Energie benötigt wird.The inventive method offers the advantage that by a presumably only short-term tempering of the electrical storage with the drive unit switched off only little energy is needed.
Ein Startwunsch des Fahrers kann auf verschiedenste Arten erkannt werden. In einer ersten Alternative wird vorteilhafterweise ein Startwunsch erkannt, wenn der Kofferraum und/oder eine Fahrzeugtür, vorzugsweise die Fahrer- Fahrzeugtür entriegelt wird. Da ein Entriegeln der Fahrertür in der Regel erst dann vorgenommen wird, wenn der Fahrer in sein Fahrzeug steigt und losfahren möchte, kann dadurch gewährleistet werden, dass die Heiz- und/oder Kühleinheit nicht zuviel Energie während des Stillstands der Antriebseinheit benötigt und dem dafür vorgesehenen elektrischen Speicher nicht unnötig lange Energie entzieht.One The driver's start request can be recognized in a variety of ways. In a first alternative is advantageously a start request detected when the trunk and / or a vehicle door, preferably the driver's vehicle door is unlocked. Because unlocking the driver's door usually only when the driver is in his vehicle get up and drive off, can be guaranteed be that the heating and / or cooling unit is not too much energy while the standstill of the drive unit needed and the designated electrical storage is not unnecessary withdraws long energy.
Ein Entriegeln der Fahrzeugtür, insbesondere der Fahrer-Fahrzeugtür erfolgt bei Fahrzeugen mit einem Funkschlüssel in der Regel dann, wenn der Fahrer ein dafür vorgesehenes Bedienelement betätigt, oder wenn der Fahrer einen Schlüssel in das Fahrzeugschloss steckt und dreht. Ist der Fahrzeugschlüssel in Form einer Sendeeinheit ausgestattet und vom Fahrzeug innerhalb eines vorgegebenen Bereichs um das Fahrzeug detektierbar, kann ein automatisches Entriegeln erfolgen, sobald ein derartiger Schlüssel vom Fahrzeug innerhalb des vorgegebenen Bereichs detektiert wird.One Unlocking the vehicle door, In particular, the driver's vehicle door is carried out on vehicles with a radio key usually when the driver has a dedicated control actuated, or if the driver has a key stuck in the vehicle lock and turns. Is the vehicle key in Formed by a transmitting unit and from within the vehicle a predetermined range around the vehicle detectable, can automatic unlocking takes place as soon as such a key from Vehicle is detected within the predetermined range.
In einer zweiten Alternative wird der Startwunsch erkannt, wenn eine Fahrzeugtür, vorzugsweise eine Fahrer-Fahrzeugtür geöffnet wird. Eine derartige Ausgestaltung der Erfindung bietet den Vorteil, dass die Wahrscheinlichkeit eines Startwunsches höher ist. Dadurch wird der elektrischen Speicher, der die Heiz- und/oder Kühleinheit mit Energie versorgt, noch weniger belastet.In a second alternative, the start request is recognized if a Vehicle door, preferably a driver's vehicle door is opened. Such Embodiment of the invention offers the advantage that the probability a start request higher is. As a result, the electric storage, the heating and / or cooling unit energized, even less burdened.
In einer dritten Alternative wird der Startwunsch erkannt, wenn eine Heiz- und/oder Kühleinheit zur Fahrzeuginnenraumtemperierung bei abgeschalteter Antriebseinheit aktiviert wird, d. h. die Temperierung des elektrischen Speichers ist an die Stillstand-Fahrzeuginnenraumtemperierung gekoppelt.In a third alternative, the start request is recognized if a Heating and / or cooling unit for vehicle interior temperature control with the drive unit switched off is activated, d. H. the temperature of the electrical storage is coupled to the stationary vehicle interior temperature control.
Sobald ein Startwunsch des Fahrers zum Starten der Antriebseinheit erkannt wird, wird ein Temperierungsvorgang zum Temperieren des elektrischen Speichers gestartet. Da der elektrische Speicher entweder erwärmt oder abgekühlt werden muss, ist bei erkanntem Startwunsch eine Temperaturab frage notwenig, damit die richtige Temperierungsart aktiviert wird. Vorteilhafterweise wird mittels der Heiz- und/oder Kühleinheit ein Erwärmen des elektrischen Speichers vorgenommen, wenn die ermittelte Außentemperatur und/oder die Temperatur des elektrischen Speichers kleiner als ein vorgegebener unterer Temperaturgrenzwert ist. Analog dazu wird mittels der Heiz- und/oder Kühleinheit ein Abkühlen des elektrischen Speichers vorgenommen wird, wenn die ermittelte Außentemperatur und/oder die Temperatur des elektrischen Speichers größer als ein vorgegebener oberer Temperaturgrenzwert ist.Once a start request of the driver to start the drive unit is detected, a Temperierungsvorgang is started for controlling the temperature of the electrical storage. Since the electrical storage must either be heated or cooled, a Temperaturab question is necessary if the start is detected, so that the right Temperierungsart is activated. Advantageously, by means of the heating and / or cooling unit, a heating of the electrical storage is carried out when the determined outside temperature and / or the temperature of the electrical storage is less than a predetermined lower temperature limit. Similarly, by means of the heating and / or cooling unit, a cooling of the electrical storage is carried out when the determined outdoor temperature and / or the temperature of the electrical storage is greater than a vorgege is the upper temperature limit.
Die aktivierte Heiz- und/oder Kühleinheit zum Temperieren des elektrischen Speichers wird wieder deaktiviert, wenn eine vorgegebene Soll-Temperatur erreicht ist, oder wenn ein vorgegebenes Zeitintervall vom Zeitpunkt der Aktivierung der Heiz- und/oder Kühleinheit erreicht oder überschritten ist, oder wenn die vorhandene Energie eines elektrischen Speichers, der die elektrische Energie zum Temperieren des elektrischen Speichers liefert, unter einen vorgegebenen Grenzwert fällt. Der elektrische Speicher, der die Energie zum Temperieren liefert, kann identisch mit dem zu temperierenden Speicher sein. Wenn keine der oben genannten Bedingungen erfüllt ist, bevor die Antriebseinheit gestartet wird, wird die Temperierung bei angeschalteter Antriebseinheit fortgesetzt. Die Solltemperatur kann in Abhängigkeit von vorgegebenen Parametern variabel vorgegeben werden.The activated heating and / or cooling unit for Tempering the electrical storage is deactivated again, when a predetermined target temperature is reached, or when a predetermined time interval from the time of activation of the heating and / or cooling unit reached or exceeded is, or if the existing energy of an electrical storage, the electrical energy for tempering the electrical storage delivers, falls below a predetermined limit. The electric storage, which supplies the energy for tempering, can be identical to the be tempered memory. If none of the above conditions is met, before the drive unit is started, the temperature control continued with the drive unit switched on. The target temperature can depend on can be set variably by predetermined parameters.
Wie bereits eingangs erwähnt, ist dieses Verfahren zum Temperieren von elektrischen Speichern vor allem für Kraftfahrzeuge geeignet, bei denen die Antriebseinheit zumindest einen Elektromotor zum Antreiben der Räder des Kraftfahrzeugs umfasst und der Elektromotor seine Energie aus eben diesem elektrischen Speicher bezieht, da derartige elektrische Speicher eine hohe Speicherkapazität benötigen und dementsprechend viel Energie speichern müssen.As already mentioned at the beginning, This method is for tempering electrical storage everything for Motor vehicles suitable in which the drive unit at least an electric motor for driving the wheels of the motor vehicle and the electric motor gets its energy from just this electrical one Memory refers, since such electrical storage require a high storage capacity and need to store a lot of energy accordingly.
