Abstract
Description
Die Erfindung bezieht sich auf eine Sicherheitsvorrichtung mit mindestens einem Sicherheitsschalter und mit mindestens einem elektronischen Steuergerät in einem Fahrzeug.The invention relates to a safety device with at least one safety switch and with at least one electronic control unit in a vehicle.
Eine derartige Sicherheitsvorrichtung ist beispielsweise aus der
Es ist Aufgabe der Erfindung, eine Sicherheitsvorrichtung zur unfallbezogenen Trennung von Fahrzeugverbrauchern von einem elektrischen Speicher zu verbessern.It is an object of the invention to improve a safety device for the accident-related separation of vehicle consumers from an electrical storage.
Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Patentanspruchs 1 gelöst. Die abhängigen Patentansprüche sind vorteilhafte Weiterbildungen der Erfindung.This object is achieved by the subject of claim 1. The dependent claims are advantageous developments of the invention.
Durch die erfindungsgemäße Sicherheitsvorrichtung mit mindestens einem Sicherheitsschalter und mit mindestens einem elektronischen Steuergerät in einem Fahrzeug ist die elektrische Verbindung oder Trennung zwischen mindestens einem Fahrzeugverbraucher und mindestens einem elektrischen Speicher steuerbar. Dabei wird durch mindestens ein elektronisches Steuergerät, das über eine Steuerleitung mit mindestens einem Sicherheitsschalter verbunden ist, bei einem Fahrzeugunfall mit vorgegebenem Ausmaß zuerst die Trennung und danach bei Vorliegen mindestens einer weiteren definierten Bedingung die erneute Verbindung zwischen dem mindestens einen Fahrzeugverbraucher und dem mindestens einen elektrischen Speicher hergestellt.By the safety device according to the invention with at least one safety switch and with at least one electronic control unit in a vehicle, the electrical connection or disconnection between at least one vehicle consumer and at least one electrical memory can be controlled. In this case, by at least one electronic control unit, which is connected via a control line with at least one safety switch, in a vehicle accident with a predetermined extent first the separation and then in the presence of at least one further defined condition, the reconnection between the at least one vehicle consumer and the at least one electrical Memory produced.
Der Erfindung liegen folgende Überlegungen, Erkenntnisse und Ideen zugrunde:
Heutige Fahrzeuge, insbesondere Hybrid- oder Elektrofahrzeuge, enthalten nicht nur elektrische Speicher in Form von 12 V Batterien, sondern auch elektrische Speicher in Form von Hochvoltbatterien, vorzugsweise Lithium- oder Super-Caps. Zum Schutz der Insassen sind derartige Hochvoltbatterien im Falle eines Unfalls erst recht vom Bordnetz oder zumindest von einem Teilumfang der elektrischen Verbraucher (z. B. auch elektrischer Antriebsmotor) in einem Fahrzeug zu trennen. Damit soll das Einspeisen weiterer elektrischer Energie vermieden werden, um das Risiko einer zusätzlichen thermischen oder elektrischen Gefahr nach einem Unfall zu reduzieren. Nach einem Fahrzeugunfall sind aber nicht nur die Insassen, sondern auch die helfenden Kräfte und die Werkstattpersonen zu schützen.The invention is based on the following considerations, findings and ideas:
Today's vehicles, especially hybrid or electric vehicles, not only contain electrical storage in the form of 12 V batteries, but also electrical storage in the form of high-voltage batteries, preferably lithium or super-caps. In order to protect the occupants, in the case of an accident, such high-voltage batteries are even more to be disconnected from the vehicle electrical system or at least from a subset of the electrical consumers (for example also the electric drive motor) in a vehicle. This is to avoid the injection of additional electrical energy to reduce the risk of additional thermal or electrical hazard after an accident. After a vehicle accident but not only the occupants, but also the helping forces and the workshop people are protected.
Daher ist es sinnvoll, insbesondere die Hochvoltbatterien möglichst schnell zu entladen, um ein ungefährliches Arbeiten am Fahrzeug zu ermöglichen. Es soll daher erfindungsgemäß eine Sicherheitsvorrichtung geschaffen werden, die ein schnelles Entladen des oder der elektrischen Speicher noch im verbauten Zustand ermöglicht.Therefore, it makes sense, in particular, to discharge the high-voltage batteries as quickly as possible to allow safe working on the vehicle. It is therefore intended according to the invention to provide a safety device which allows a rapid discharge of the electric storage or even in the installed state.
Durch die Erfindung kann mit bisher bekannten Sicherheitsvorrichtungen eine sichere Steuerung der wieder verschließbaren Sicherheitsschalter geschaffen werden, so dass der elektrische Speicher an beliebiger Stelle im Fahrzeug mittels eines Verbrauchers entladen werden kann.By means of the invention, with previously known safety devices, a secure control of the resealable safety switches can be provided, so that the electrical accumulator can be unloaded at any point in the vehicle by means of a load.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Es zeigtIn the drawings, embodiments of the invention are shown. It shows
Die Stromversorgungsleitungen sind insbesondere mit dem zweiten elektrischen Speicher
Erfindungsgemäß wird nun danach bei Vorliegen mindestens einer weiteren definierten Bedingung die Verbindung zwischen den stromlos geschalteten Verbrauchern – hier dargestellt die Verbraucher
Je nach Ort der anzusteuernden Sicherheitsschalter kann entweder das zweite Steuergerät
Ergänzend liegen der Erfindung noch folgende auch eigenständige Zusatzideen zugrunde: Zum Entladen der Hochvoltbatterie
Auch könnte zusätzlich oder alternativ ein Steuergerät
