Die Anzahl von elektrischen Verbrauchern in einem Kraftfahrzeug hat enorm zugenommen und führen zu erhöhten Belastungen des Bordnetzes des Kraftfahrzeuges. Insbesondere können Hochstromverbraucher, die u. U. gleichzeitig das Bordnetz belasten zu einer Gefährdung der Betriebssicherheit des Kraftfahrzeuges führen.The Number of electrical consumers in a motor vehicle has enormously increased and lead to increased Loads of the electrical system of the motor vehicle. In particular, high current consumers, the u. U. simultaneously load the electrical system to a threat to the Operational safety of the motor vehicle lead.
Das Bordnetz eines Kraftfahrzeuges wird von mindestens einem Generator und mindestens einem elektrischen Energiespeicher, bspw. einer Batterie übernommen. Auf rasche Stromänderungen oder auf die o. g. Belastungen aufgrund von gleichzeitigen Eingriffen von Hochstromverbrauchern kann aufgrund der geringen Dynamik des Generators dieser hierauf nicht reagieren und daher müssen solche Situationen ausschließlich durch die im Bordnetz installierten Energiespeicher abgefangen werden. Hochstromverbraucher existieren bspw. nicht nur für Starter bzw. Anlasser und elektrische Fensterheber, sondern auch für die elektrische Bremse, die elektrohydraulische Bremse, für eine elektrisch unterstütze Lenkung (EPS) oder einen elektrische Zusatzverdichter.The Vehicle electrical system of a motor vehicle is powered by at least one generator and at least one electrical energy store, for example a battery. On rapid power changes or on the o. g. Burdens due to simultaneous interventions of high current loads may be due to the low dynamics of the Generators of this do not react to this and therefore need such Situations exclusively be intercepted by the energy stored in the electrical system. High-current consumers exist, for example, not only for starters or starter and power windows, but also for the electric Brake, the electrohydraulic brake, for electrically assisted steering (EPS) or an electric auxiliary compressor.
Sollte die angeforderte Leistung vom Bordnetz des Kraftfahrzeuges aufgrund einer zu hohen kurzzeitigen Belastung durch mehrere Hochstromverbraucher nicht bereitgestellt werden können, kann dies zu sicherheitsrelevanten Situation führen und bspw. besonders kritisch für die Betriebssicherheit von für das Fahrzeug sicherheitsrelevante Systeme, wie z. Bsp. für Fahrwerksregelsysteme, insbesondere elektromechanische Bremsanlagen oder Lenksysteme werden.Should the requested power from the electrical system of the motor vehicle due too high a short-term load by several high-current consumers can not be provided This can lead to security-relevant situation and, for example, particularly critical for the Operational safety of for the vehicle safety-related systems, such. Eg for chassis control systems, in particular electromechanical brake systems or steering systems.
Aufgabe der Erfindung ist es, ein Verfahren zur Steuerung mehrerer elektrische Verbraucher, insbesondere sicherheitsrelevanter Hochstromverbraucher eines Kraftfahrzeugs anzugeben, das eine hohe Belastung des Bordnetzes vermeidet, bzw. die Wahrscheinlichkeit eines Totalausfalls maßgeblich reduziert.task The invention is a method for controlling a plurality of electrical Consumers, in particular safety-related high current consumers indicate a motor vehicle, the high load on the electrical system avoids, or the probability of total failure significantly reduced.
Diese Aufgabe wird gelöst durch ein Verfahren gemäß den Merkmalen des Patentanspruches 1.These Task is solved by a method according to the features of claim 1.
Gemäß diesem erfindungsgemäßen Verfahren zur Steuerung von mehreren aus einem elektrischen Energiespeicher mit Betriebsstrom betriebenen elektrischen Verbrauchern eines Bordnetzes für Kraftfahrzeuge wird ein den zukünftigen und/oder aktuellen Zustand des Bordnetzes anzeigender Indikator erfasst und in Abhängigkeit des erfassten Indikators wenigstens ein vorbestimmter Verbraucher in einen Teillastbetrieb gesteuert.According to this inventive method for controlling several of an electrical energy storage with operating current operated electrical loads of a vehicle electrical system for motor vehicles becomes the future one and / or current state of the electrical system indicating indicator recorded and dependent of the detected indicator at least one predetermined consumer controlled in a partial load operation.
Damit wird durch kontrolliertes Herabsetzen der Leistung eines vorbestimmten elektrischen Verbrauchers die Belastung des Bordnetzes reduziert, ohne dass dies im Falle von sicherheitsrelevanten Verbrauchern zu sicherheitskritischen Situationen führen kann.In order to is controlled by lowering the power of a predetermined electrical load reduces the load on the electrical system, without that this is safety-critical in the case of safety-relevant consumers Situations lead can.
Besonders vorteilhaft ist es, wenn der vorbestimmte Verbraucher nur für einen vorbestimmten Zeitraum in dem Teillastbetrieb betrieben wird, um möglichst frühzeitig wieder die volle Leistung diesem Verbraucher zuführen zu können.Especially It is advantageous if the predetermined consumer only for one predetermined period is operated in the partial load operation, if possible early to bring the full power back to this consumer.
Bei einer Weiterbildung der Erfindung wird als Indikator die Verfügbarkeit des Energiespeichers erfasst. Unter dem Begriff Verfügbarkeit wird insbesondere die Stromlieferfähigkeit des Energiespeichers, bspw. einer Batterie verstanden. Wenn keine Verfügbarkeit bzw. die Stromlieferfähigkeit nicht angezeigt wird, kann dies unterschiedliche Ursachen habe; so kann bspw. der Energiespeicher unter einen bestimmten Ladezustand gefallen oder auch vollständig ausgefallen sein; die Verfügbarkeit wäre auch dann nicht mehr gegeben, wenn die elektrische Verbindung zum Energiespeicher unterbrochen wäre. Zeigt der Indikator die fehlende Verfügbarkeit an, wird der vorbestimmte Verbraucher in den Teillastbetrieb gesteuert. Zur Erzeugung eines solchen Indikators ist vorzugsweise ein Batteriediagnose-Modul vorgesehen, das diesen Indikator als Steuersignal über eine Datenbus-Leitung dem in den Teillastbetrieb zu steuernden Verbraucher zuführt.at a development of the invention is as an indicator of availability of the energy storage detected. Under the term availability In particular, the power supply capability of the energy store, For example, a battery understood. If no availability or power delivery capability not displayed, this may have different causes; For example, the energy store may be under a certain state of charge fallen or completely to be out of order; the availability would be too then no longer given when the electrical connection to the energy storage would be interrupted. If the indicator indicates the lack of availability, the predetermined Consumer controlled in the partial load operation. To generate a such indicator, a battery diagnosis module is preferably provided, the this indicator as a control signal via a data bus line the feeds into the part load operation to be controlled.
Bei einer anderen Weiterbildung der Erfindung wird als Indikator die Betriebsstromanforderung oder die Ankündigung eines Betriebs eines sicherheitsrelevanten Verbrauchers erfasst und hierauf der vorbestimmte Verbraucher in den Teillastbetrieb gesteuert. Vorzugsweise ist zur Erzeugung des Indikators „Betriebsstromanforderung eines sicherheitsrelevanten Verbrauchers” oder des Indikators „Ankündigung eines Betriebs eines sicherheitsrelevanten Verbrauchers” ein Regler für eine Bremsanlage (ESP) mit Blockierschutz- und Antriebsschlupfregelung vorgesehen, wobei vorzugsweise auch dieser Indikator als Steuersignal über eine Datenbus-Leitung dem in den Teillastbetrieb zu steuernden Verbraucher zugeführt wird. Insbesondere zeigt der Regler der Bremsanlage (EPS) als Indikator einen hohen Strombedarf an, der bspw. durch einen Pumpenanlauf der Bremsanlage ausgelöst werden kann.at another embodiment of the invention is as an indicator the Operating power request or the announcement of an operation of a safety relevant consumer and then the predetermined Consumer controlled in the partial load operation. Preferably, the Generation of the indicator "operating current demand a safety-related consumer "or indicator" announcement an operation of a safety-relevant consumer "a regulator for one Brake system (ESP) with anti-lock and traction control provided, preferably also this indicator as a control signal via a Data bus line to the consumer to be controlled in partial load operation supplied becomes. In particular, the controller shows the brake system (EPS) as an indicator a high power consumption, the example. By a pump start the Brake system triggered can be.
Bei einer besonders bevorzugten Weiterbildung der Erfindung ist als vorbestimmter Verbraucher eine elektromechanische Servolenkung vorgesehen, dessen Regler der Indikator als Steuersignal zugeführt wird.at A particularly preferred embodiment of the invention is as predetermined consumer provided an electromechanical power steering, whose regulator the indicator is supplied as a control signal.
