In a safety device in motor vehicles with a controllable safety switch for switching off the electric current of the vehicle's electric system, which electric current is output by the battery of a motor vehicle, a control unit is provided which identifies a signal in order to detect a starting process, determines the current drawn from the battery and opens the controllable safety switch if no starting process is present and the value of the current drawn from the battery is higher than a prescribed short-circuit limit value.

Description

Die Erfindung bezieht sich auf eine Sicherheitsvorrich­ tung in Kraftfahrzeugen mit einem steuerbaren Sicher­ heitsschalter zum Abschalten des durch eine Kraftfahr­ zeugbatterie abgegebenen elektrischen Stromes vom Bord­ netz.The invention relates to a safety device device in motor vehicles with a controllable safety safety switch for switching off by a motor vehicle electric battery delivered electrical power from the board network.

Eine derartige Sicherheitsvorrichtung ist beispielsweise aus der DE 34 17 328 C2 bekannt. Diese bekannte Sicher­ heitsvorrichtung enthält zum Trennen der Kraftfahrzeug­ batterie vom Bordnetz einen Sicherheitsschalter, der von einem Tastschalter gesteuert wird, der auf eine bei Un­ fällen auftretende Verformung der Karosserie anspricht.Such a safety device is for example known from DE 34 17 328 C2. This well-known sure Unit contains for separating the motor vehicle battery from the vehicle electrical system a safety switch by a key switch is controlled, which is set to one at Un in case of deformation of the body.

Eine weitere Sicherheitsvorrichtung zum Trennen der Kraftfahrzeugbatterie vom Bordnetz ist aus der DE 26 57 738 A1 bekannt, bei der die Kraftfahrzeugbatterie bei Un­ fällen automatisch vom Bordnetz mittels eines Sicher­ heitsschalters abgetrennt wird, der auf Verzögerungen und Überschlagen des Fahrzeuges anspricht.Another safety device to separate the Motor vehicle battery from the vehicle electrical system is from DE 26 57 738 A1 known in which the motor vehicle battery at Un fall automatically from the vehicle electrical system using a safe is disconnected on delay and Overturning the vehicle.

Ferner ist eine Sicherheitsvorrichtung aus der DE 29 08 885 A1 bekannt, bei der der Sicherheitsschalter zum Tren­ nen der Kraftfahrzeugbatterie vom Bordnetz durch den Ein­ fluß einer trägen Masse gesteuert wird, wenn das Fahrzeug unfallbedingt hohen Verzögerungs- oder Beschleunigungs­ kräften ausgesetzt ist. Furthermore, a security device from DE 29 08 885 A1 known, in which the safety switch for opening NEN the motor vehicle battery from the vehicle electrical system through the one Flow of an inertial mass is controlled when the vehicle high deceleration or acceleration due to accident is exposed to forces.  

Mittels derartiger Sicherheitsvorrichtungen zum Trennen einer Kraftfahrzeugbatterie vom Bordnetz wird eine auto­ matische Batterieabschaltung vorgenommen, um bei Unfällen durch Quetschungen der Kabel Kurzschlußfolgen wie z. B. Kabelbrände zu verhindern. Die bekannten Sicherheitsvor­ richtungen benötigen dazu aufwendige Sensorvorrichtungen, wie z. B. Verzögerungssensoren, Crash-Sensoren oder Ver­ formungssensoren, um einen Unfall automatisch zu erken­ nen. Darüber hinaus wird bei der bekannten Sicherheitsvor­ richtung die Kraftfahrzeugbatterie vom Bordnetz bei einem Unfall jederzeit und sofort getrennt, wodurch ein unnöti­ ges oder zu frühes Trennen der Kraftfahrzeugbatterie be­ wirkt wird. Dadurch besteht beispielsweise die Gefahr, daß sicherheitsrelevante Systeme, wie z. B. der Airbag oder der Überrollschutz, durch die fehlende Energieversorgung nicht mehr ausgelöst werden.By means of such safety devices for separation A motor vehicle battery from the vehicle electrical system becomes an auto Matic battery shutdown made to in case of accidents by squeezing the cable short-circuit consequences such. B. To prevent cable fires. The well-known security pre directions require complex sensor devices for this, such as B. delay sensors, crash sensors or Ver shaping sensors to automatically detect an accident nen. In addition, the well-known security direction the motor vehicle battery from the electrical system at one Accident separated at any time and immediately, making an unnecessary total or early disconnection of the motor vehicle battery will work. There is a risk, for example, that security systems such. B. the airbag or the rollover protection, due to the lack of energy supply can no longer be triggered.

Es ist Aufgabe der Erfindung eine Sicherheitsvorrichtung zu schaffen, die den durch eine Kraftfahrzeugbatterie ab­ gegebenen elektrischen Strom nur dann abschaltet bzw. die Kraftfahrzeugbatterie vom Bordnetz nur dann trennt, wenn tatsächlich ein Kurzschluß zwischen den Batterieversor­ gungsleitungen auftritt, und die diese Abschaltung bzw. Trennung nicht nur bei Vorliegen eines Unfalles vornimmt.The object of the invention is a safety device to create that by a car battery only switches off the given electrical current or the Only disconnects the motor vehicle battery from the vehicle electrical system if actually a short circuit between the battery suppliers power lines occurs, and this shutdown or Separation does not only take place in the event of an accident.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This task is characterized by the characteristics of the Claim 1 solved.

Erfindungsgemäß enthält die Sicherheitsvorrichtung eine Steuereinheit, die ein Signal zur Erkennung eines Anlaß­ vorganges erfaßt, den aus der Batterie entnommenen Strom ermittelt und den steuerbaren Sicherheitsschalter zum Trennen der Kraftfahrzeugbatterie vom Bordnetz nur dann öffnet, wenn kein Anlaßvorgang vorliegt und der Wert des aus der Batterie entnommenen Stromes größer als ein vor­ gegebener Kurzschlußgrenzwert ist. According to the invention, the safety device contains a Control unit that sends a signal to detect an occasion event detects the current drawn from the battery determined and the controllable safety switch to Only then disconnect the vehicle battery from the vehicle electrical system opens when there is no starting process and the value of the current drawn from the battery is greater than one before given short circuit limit.  

Vorzugsweise ist der Sicherheitsschalter zwischen dem Mi­ nuspol der Kraftfahrzeugbatterie und dem zugehörigen Mas­ sestützpunkt angebracht, um bei parallel geschalteten Kraftfahrzeugbatterien mit nur einem Schalter sämtliche Batterien gleichzeitig vom Bordnetz zu trennen. Der Si­ cherheitsschalter kann aber z. B. auch zwischen dem Bord­ netz und dem Pluspol der Batterie angebracht sein.Preferably, the safety switch between the Mi nuspol of the motor vehicle battery and the associated Mas base attached to when connected in parallel Motor vehicle batteries with just one switch all Disconnect batteries from the electrical system at the same time. The Si Safety switch can, for. B. also between the board mains and the positive pole of the battery.

Der aus der Batterie entnommene Strom wird beispielsweise durch Messung des Spannungsabfalls an einem Meßwider­ stand, über den der von der Batterie entnommene Strom fließt und der auch ein definierter geeichter Leitungsab­ schnitt sein kann, von der Steuereinheit ermittelt. Der Anlaßvorgang wird beispielsweise durch das Signal des An­ laßschalters (Klemme 50) erkannt. Es sind jedoch auch an­ dere Signale zur Erkennung eines Anlaßvorganges erfaßbar, wie z. B. die Drehzahl der Brennkraftmaschine, die nur nach einem Anlaßvorgang beispielsweise einen bestimmten Grenzwert erreichen kann. Wird ein Betrieb nach dem An­ laßvorgang als Normalbetrieb bezeichnet, so wird der Kurzschlußgrenzwert insbesondere derart vorgegeben, daß er ein Vielfaches - vorzugsweise das Dreifache - des im Normalbetrieb maximal möglichen Stromwertes beträgt. Da bei einem Anlaßvorgang der aus der Batterie entnommene Strom kurzzeitig gleich einem Kurzschlußgrenzwert sein kann, wird der Sicherheitsschalter nur dann geöffnet, wenn kein Anlaßvorgang vorliegt. Somit wird einerseits ein unnötiges Trennen der Kraftfahrzeug vom Bordnetz ver­ hindert, bei Vorliegen eines Kurzschlusses jedoch eine zuverlässige Trennung der Kraftfahrzeugbatterie vom Bord­ netz bewirkt.The current drawn from the battery is determined, for example, by measuring the voltage drop at a measuring resistor, via which the current drawn from the battery flows and which can also be a defined calibrated line section, determined by the control unit. The starting process is detected, for example, by the signal from the on switch (terminal 50 ). However, there are also other signals to detect a starting process, such as. B. the speed of the internal combustion engine, which can only reach a certain limit, for example, only after a starting process. If operation after the start-up process is referred to as normal operation, the short-circuit limit value is in particular predetermined such that it is a multiple - preferably three times - of the maximum possible current value in normal operation. Since the current drawn from the battery can briefly be equal to a short-circuit limit value during a starting process, the safety switch is only opened when there is no starting process. Thus, on the one hand, an unnecessary disconnection of the motor vehicle from the vehicle electrical system is prevented, however, in the presence of a short circuit, the motor vehicle battery is reliably disconnected from the vehicle electrical system.

Eine vorteilhafte Weiterbildung ist der Gegenstand des Patentanspruchs 2. An advantageous development is the subject of Claim 2.  

Liegt die Bedingung zum Öffnen des steuerbaren Sicher­ heitsschalters vor, wird der Sicherheitsschalter erst nach einer vorgegebenen Zeitverzögerung tatsächlich ge­ öffnet. Die vorgegebene Zeitdauer zum Verzögern des Ab­ schaltvorgangs ist vorzugsweise derart definiert, das ein zuverlässiges Auslösen von Sicherheitssystemen, wie z. B. des Airbags, gerade noch gewährleistet ist. Jedoch ist diese vorgegebene Zeitdauer ausreichend kurz zu wählen, damit die zu schützenden Leitungen keine zum Schmelzen der Isolierung führenden Temperaturen erreichen.The condition for opening the controllable safe is safety switch before, the safety switch is only actually ge after a predetermined time delay opens. The specified time to delay the Ab switching process is preferably defined in such a way that a reliable triggering of security systems, such as B. of the airbag is just still guaranteed. However is to choose this predetermined period of time sufficiently short, so that the lines to be protected do not melt insulation temperatures.

In der Zeichnung ist ein Ausführungsbeispiel der Erfin­ dung dargestellt. Sie zeigt eine Steuereinheit zur Durch­ führung der erfindungsgemäßen Funktionen.In the drawing is an embodiment of the Erfin shown. It shows a control unit for the through management of the functions according to the invention.

Die Steuereinheit in Form eines Steuergeräts SG enthält einen ersten Eingang zum Erfassen des Signals SA zur Er­ kennung eines Anlaßvorganges. Das Signal SA ist in diesem Beispiel das Signal des Anlasserschalters.The control unit in the form of a control unit SG contains a first input for detecting the signal S A to identify a starting process. In this example, the signal S A is the signal from the starter switch.

An zwei weiteren Eingängen des Steuergerätes SG liegt die am Meßwiderstand RM abfallende Spannung UM an. Dieser Spannungsabfall UM wird als Maß für den aus der Batterie B entnommenen Strom IB herangezogen (IB∼ UM). Über den Meßwiderstand RM fließt der gesamte aus der Batterie B entnommene Strom IB.The voltage U M dropping across the measuring resistor R M is present at two further inputs of the control unit SG. This voltage drop U M is used as a measure of the current I B drawn from the battery B (I B ∼ U M ). The entire current I B drawn from the battery B flows through the measuring resistor R M.

Der Ausgang des Steuergeräts SG ist mit einem steuerbaren Sicherheitsschalter SS verbunden. Der steuerbare Sicher­ heitsschalter SS ist zwischen der Fahrzeugbatterie B und dem Massestützpunkt der Batterie B angeordnet.The output of the control unit SG is connected to a controllable safety switch S S. The controllable safety switch S S is arranged between the vehicle battery B and the ground point of the battery B.

Zwischen dem Bordnetz BN, das beispielsweise verschiedene Verbraucher V enthält, und dem Pluspol der Batterie B ist der Meßwiderstand RM angeordnet. The measuring resistor R M is arranged between the on-board electrical system BN, which contains various consumers V, for example, and the positive pole of the battery B.

Im Steuergerät SG wird der aus der Batterie entnommene, aus dem Spannungsabfall UM ermittelte Strom IB mit einem Kurzschlußgrenzwert IKS verglichen. Ist der der Batterie B entnommene Strom IB größer als der im Steuergerät vorgegebene Kurzschlußgrenzwert IKS, gibt das Steuergerät SG einen Befehl zum Öffnen des steuerbaren Schalters SS an ein Zeitverzögerungsglied mit der Zeitdauer δt aus. Liegt dieser Befehl zum Öffnen des Sicherheitsschalters SS länger als die vorgegebene Zeitdauer δt des Verzöge­ rungsgliedes an, wird der steuerbare Schalter S von der geschlossenen Position 1 in die offene Position 0 überge­ führt. Damit wird der von der Batterie B gelieferte Strom IB vom Bordnetz BN abgeschaltet.In the control unit SG, the current I B taken from the battery and determined from the voltage drop U M is compared with a short-circuit limit value I KS . If the battery B discharged current I B is greater than the predetermined in the control unit short circuit limit value I KS, the control unit SG is a command for opening the controllable switch S S in a time-delay element with the time duration of .delta.t. If this command to open the safety switch S S is longer than the predetermined time period δt of the delay element, the controllable switch S leads from the closed position 1 to the open position 0. The current I B supplied by the battery B is thus switched off from the electrical system BN.

Der steuerbare Sicherheitsschalter SS kann auch alterna­ tiv oder zusätzlich auf der Seite des Pluspols der Batte­ rie B angeordnet sein. Der (oder die) Schalter SS ist (sind) beispielsweise elektromagnetisch betätigbar. Ein erfindungsgemäßer steuerbarer Sicherheitsschalter SS kann jedoch auch als Schalter mit elektromotorischem Antrieb oder als Leistungshalbleiterschalter ausgestaltet sein.The controllable safety switch S S can alternatively or additionally be arranged on the side of the positive pole of the battery B. The switch (s) S (s) can be operated electromagnetically, for example. However, a controllable safety switch S S according to the invention can also be designed as a switch with an electric motor drive or as a power semiconductor switch.

Durch diese erfindungsgemäße Ausgestaltung wird bei Vor­ liegen eines Kurzschlußstromes auf der Batterieversor­ gungsleitung entweder die Kraftfahrzeugbatterie zuverläs­ sig isoliert oder der Strom der Kraftfahrzeugbatterie ab­ geschaltet, um einen Kabelbrand zu verhindern. Gleichzei­ tig werden die Sicherheitssysteme bei einem Unfall durch die Verzögerung der Stromabschaltung noch sicher wirksam.Through this configuration according to the invention is in front are a short-circuit current on the battery supplier supply line either the motor vehicle battery sig isolated or the current of the motor vehicle battery switched to prevent a cable fire. Simultaneously The safety systems become effective in the event of an accident the delay of the power cut is still effective.
