Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Speicherung des Auftretens eines Signals für ein Steuergerät. The invention relates to a device and a method for storing the occurrence of a signal for a control device.

Dabei ist es wünschenswert, dass das Steuergerät das Auftreten des Crash-Signals oder eines ähnlichen Signals abspeichert. Dabei tritt nun das Problem auf, dass, die Spannungsversorgung des Steuergeräts aufgrund von Störungen (z.B. Kurzschlüsse) nach einem Ereignis wie z.B. Crash, zusammenbrechen kann, sodass ein Speichervorgang so gestört wird, dass dieser nicht zu Ende erfolgen kann. Zur Lösung ist es daher bekannt, dem Steuergerät lokal einen Kondensator oder eine Stützbatterie zuzuordnen, die einen zu schnellen Zusammenbruch der Versorgungsspannung des Steuergerätes verhindern. Allerdings benötigen diese zusätzlichen lokalen Spannungsversorgungen Bauraum. It is desirable that the controller stores the occurrence of the crash signal or a similar signal. The problem now arises that the power supply of the control unit due to disturbances (for example short circuits) after an event such as e.g. Crash, can collapse, so that a storage process is disturbed so that it can not be completed. To solve it is therefore known to assign the controller locally a capacitor or a backup battery, which prevent a too rapid collapse of the supply voltage of the control unit. However, these additional local power supplies require space.
Der Erfindung liegt das technische Problem zugrunde, eine Vorrichtung zur Speicherung des Auftretens eines Signals für ein Steuergerät zu schaffen sowie ein solches Verfahren zur Verfügung zu stellen, die ohne zusätzliche Stützbatterien oder Kondensatoren zur Spannungsversorgung auskommen. The invention is based on the technical problem of providing a device for storing the occurrence of a signal for a control device and to provide such a method that manage without additional backup batteries or capacitors for power supply.
Die Lösung des technischen Problems ergibt sich durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 sowie ein Verfahren mit den Merkmalen des Anspruchs 8. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. The solution to the technical problem results from a device having the features of
Die Vorrichtung zur Speicherung des Auftretens eines Signals einer Signalquelle für ein Steuergerät weist zunächst das Steuergerät selbst auf. Dabei sind Signalquelle und das Steuergerät über mindestens eine Leitung miteinander verbunden. Zwischen der Signalquelle und dem Steuergerät ist mindestens eine Sicherung angeordnet, die derart dimensioniert ist, dass die Sicherung durch das Signal auslöst, wobei das Steuergerät Mittel aufweist, mittels derer eine Unterbrechung der mindestens einen Leitung erfassbar ist. Somit stellt die Sicherung das Speichermittel dar, wobei durch die Mittel der Inhalt des Speichers abrufbar ist, nämlich ob das Signal aufgetreten ist oder nicht. Das Ansprechen der Sicherung erfolgt dabei erheblich schneller als ein regulärer Speichervorgang im Steuergerät, sodass auch bei einem Zusammenbruch der Versorgungsspannung des Steuergeräts die Abspeicherung noch sicher erfolgen kann. Wenn dann zu einem späteren Zeitpunkt das Steuergerät wieder hochfährt, kann durch Abfragen des Zustandes der Sicherung bzw. Leitung auf das Auftreten des Signals geschlossen werden und beispielsweise eine Wiederzuschaltung einer abgetrennten Batterie unterbunden werden, bevor nicht durch geschultes Service-Personal die Unversehrtheit des elektrischen Systems überprüft wurde. Das Service-Personal kann dann nach der Überprüfung die Sicherung auswechseln. The device for storing the occurrence of a signal of a signal source for a control device initially has the control device itself. Signal source and the control unit are connected to each other via at least one line. Between the signal source and the control unit at least one fuse is arranged, which is dimensioned such that the fuse triggers by the signal, wherein the control device comprises means by which an interruption of the at least one line can be detected. Thus, the backup is the storage means, whereby the content of the memory is retrievable by the means, namely whether the signal has occurred or not. The response of the backup takes place much faster than a regular storage process in the control unit, so even with a collapse of the supply voltage of the controller, the storage can still be done safely. If then at a later time, the control unit starts up again, can be closed by querying the state of the fuse or line on the occurrence of the signal and, for example, a reconnection of a disconnected battery are prevented, not by trained service personnel, the integrity of the electrical system was checked. Service personnel can then replace the fuse after verification.
In einer Ausführungsform weist die Leitung eine gesteuerte Verzweigung in mindestens zwei parallele Leitungsabschnitte und eine gesteuerte Zusammenführung auf, die die parallelen Leitungsabschnitte wieder auf einen gemeinsamen Leitungsabschnitt zusammenführt, wobei in jedem parallelen Leitungsabschnitt eine Sicherung angeordnet ist. Dabei ist die Verzweigung vorzugsweise als Demultiplexer und die Zusammenführung als Multiplexer ausgebildet. Hierdurch ist es möglich, durch Umschaltung auf einen anderen parallelen Leitungsabschnitt das elektrische System wieder in Betrieb zu nehmen, ohne die ausgelöste Sicherung zu wechseln. Die Anzahl der parallelen Leitungsabschnitte kann dabei je nach Anwendungsgebiet schwanken. Einen sehr guten Kompromiss stellen dabei vier parallele Leitungsabschnitte dar, die dann durch zwei Steuersignale ausgewählt werden können. In one embodiment, the conduit has a controlled branching into at least two parallel conduit sections and a controlled combination which reunites the parallel conduit sections to a common conduit section, wherein a fuse is arranged in each parallel conduit section. The branch is preferably designed as a demultiplexer and the merger as a multiplexer. This makes it possible, by switching to another parallel line section to take the electrical system back into operation without changing the triggered fuse. The number of parallel line sections can vary depending on the field of application. A very good compromise is four parallel line sections, which can then be selected by two control signals.
In einer weiteren Ausführungsform ist das Steuergerät als Batterie-Steuergerät ausgebildet, insbesondere kann die Vorrichtung in einem Elektro- oder Hybridfahrzeug zum Einsatz kommen. In diesen Anwendungsfällen ist dann das Steuergerät vorzugsweise ein Batterie-Steuergerät für eine Hochvolt- bzw. Traktionsbatterie des Fahrzeugs. In a further embodiment, the control unit is designed as a battery control unit, in particular, the device can be used in an electric or hybrid vehicle. In these applications, then the controller Preferably, a battery control device for a high-voltage or traction battery of the vehicle.
In einer weiteren Ausführungsform ist das Steuergerät derart ausgebildet, dass bei Erfassung des Signals mindestens eine Batterie abgetrennt wird. In einem Elektro- oder Hybridfahrzeug ist dies vorzugsweise die Hochvoltbatterie. Zusätzlich kann aber auch, falls vorhanden, eine Bordnetzbatterie mitabgetrennt werden. In a further embodiment, the control unit is designed in such a way that at least one battery is disconnected when the signal is detected. In an electric or hybrid vehicle, this is preferably the high-voltage battery. In addition, however, if available, an on-board battery can be mitabgetrennt.
Dabei ist das Steuergerät in einer weiteren Ausführungsform derart ausgebildet, dass eine Wieder-Zuschaltung der abgetrennten Batterie erst wieder möglich ist, wenn die ausgelöste Sicherung ausgetauscht wird oder der gemeinsame Leitungsabschnitt mit einem parallelen Leitungsabschnitt mit intakter Sicherung verbunden wird. In this case, the control device is formed in a further embodiment such that a re-connection of the disconnected battery is only possible again when the triggered fuse is replaced or the common line section is connected to a parallel line section with intact fuse.
Hinsichtlich der verfahrensmäßigen Ausbildung der Erfindung wird vollinhaltlich auf die vorangegangenen Ausführungen Bezug genommen. With regard to the procedural embodiment of the invention, reference is made in full to the preceding statements.
Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels näher erläutert.
