Schließlich offenbart die US-A-5 254 842 ein Wegfahrsperrensteuergerät und die US-A-5 708 335 zeigt eine Steuerung zur Personalisierung eines Kraftfahrzeugs.Finally, US-A-5 254 842 discloses an immobilizer control apparatus and US-A-5 708 335 shows a control for personalizing a motor vehicle.
Es ist Aufgabe der Erfindung, ein Kraftfahrzeug der eingangs genannten Art zu schaffen, dessen Diagnosestecker eine hohe Funktionalität aufweist und dessen übrigen elektrischen Komponenten bestimmungsgemäß verwendet werden können.It is an object of the invention to provide a motor vehicle of the type mentioned, whose diagnostic connector has a high functionality and the remaining electrical components can be used as intended.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Diagnosestecker zum elektrischen Anschluss mindestens eines Zusatzgerätes ausgebildet und dem Diagnosestecker (3) eine Schaltung zum Schutz einer Fahrzeugbatterie vor Entladung zugeordnet ist.According to the invention the object is achieved in that the diagnostic connector is designed for the electrical connection of at least one auxiliary device and the diagnostic connector (3) is associated with a circuit for protecting a vehicle battery before discharge.
Aufgrund dieser Maßnahme ist die bestimmungsgemäße Verwendung des Zigarettenanzünders und eine gleichzeitige Spannungsversorgung eines elektrischen Zusatzgerätes gewährleistet. Darüber hinaus ist der Diagnosestecker auch bei ausgeschalteter Zündung des Kraftfahrzeuges mit Spannung aus dem Bordnetz beaufschlagt, so dass ein dauerhafter Betrieb des an den Diagnosestecker angeschlossenen Zusatzgerätes, beispielsweise eines Kühlschrankes, einer Handlampe oder eines elektronischen Gerätes, sichergestellt ist. Der Entladungsschutz sorgt dafür, dass eine zum Starten des Kraftfahrzeuges, also zum Betrieb eines elektrischen Anlassers, genügende Spannung seitens der Fahrzeugbatterie zur Verfügung gestellt wird. Beim Erreichen einer Minimalspannung wird die Spannungsversorgung des elektrischen Zusatzgerätes über die dem Diagnosestecker zugeordnete Schaltung abgeschaltet.Due to this measure, the intended use of the cigarette lighter and a simultaneous power supply of an electrical accessory is guaranteed. In addition, the diagnostic connector is supplied with voltage from the electrical system even when the ignition of the motor vehicle is switched off, so that a permanent operation of the connected to the diagnostic connector accessory, such as a refrigerator, a flashlight or an electronic device is ensured. The discharge protection ensures that a sufficient voltage for starting the motor vehicle, ie for operating an electric starter, is provided by the vehicle battery. When a minimum voltage is reached, the power supply of the electrical auxiliary device is switched off via the circuit assigned to the diagnostic connector.
Zweckmäßigerweise weist das Zusatzgerät eine separate Spannungsversorgung auf. Eine separate Spannungsversorgung hält die Funktionsfähigkeit des Zusatzgerätes auch dann aufrecht, falls der Entladungsschutz für die Fahrzeugbatterie anspricht und die Spannungsversorgung des Zusatzgerätes unterbricht oder ein die Spannungsversorgung unterbrechender Fehler im Bordnetz vorliegt. Somit stellt die separate Spannungsversorgung einen Notbetrieb des Zusatzgerätes sicher. Die zusätzliche Spannungsversorgung ermöglicht auch den Betrieb des Zusatzgerätes nach einer Entkopplung von dem Diagnosestecker, so dass beispielsweise ein Kühlschrank oder eine Handlampe mitgenommen werden kann. Zur Spannungsversorgung kann beispielsweise mindestens ein Akkumulator oder mindestens eine Batterie vorgesehen sein.Appropriately, the attachment has a separate power supply. A separate power supply maintains the functionality of the attachment even if the discharge protection for the vehicle battery responds and interrupts the power supply of the auxiliary device or there is a power supply interrupting fault in the electrical system. Thus, the separate power supply ensures emergency operation of the additional device. The additional power supply also allows the operation of the attachment after a decoupling of the diagnostic connector, so that, for example, a refrigerator or a flashlight can be taken. For example, at least one accumulator or at least one battery can be provided for the voltage supply.

Auf diese Weise lassen sich mehrere elektrische Zusatzgeräte über den Diagnosestecker dauerhaft mit Spannung beaufschlagen, wobei die Zusatzgeräte üblicherweise mit einem Stecker in Form eines Zigarettenanzünders versehen sind.Preferably, the attachment is coupled via an adapter to the diagnostic connector. This adapter can for example be designed to be compatible with the diagnostic connector and the other to the cigarette lighter. It is conceivable that the adapter has several suitable socket contacts for receiving a cigarette lighter. In this way, several electrical accessories over the diagnostic connector permanently apply voltage, the accessories are usually provided with a plug in the form of a cigarette lighter.
Zweckmäßigerweise ist die Schaltung zum Schutz vor Entladung der Fahrzeugbatterie in den Adapter integriert. Diese Schaltung ist in erster Linie beim Betrieb elektrischer Zusatzgeräte erforderlich und steht bei ihrer Integration in den Adapter bei der Verwendung des Adapters zur Verfügung. Die Ausstattung jedes Kraftfahrzeuges mit einer solchen Schaltung ist daher nicht erforderlich.Conveniently, the circuit for protection against discharge of the vehicle battery is integrated in the adapter. This circuit is required primarily in the operation of electrical accessories and is in their integration into the adapter when using the adapter available. The equipment of each motor vehicle with such a circuit is therefore not required.

Damit ist ein wirksamer Diebstahlschutz des Kraftfahrzeuges gegeben, da es sich ohne das Wegfahrsperren-Steuergerät nicht starten lässt.Preferably, the controller is designed as an immobilizer control unit. For safety reasons, if a user of the motor vehicle leaves the same, he can remove the immobilizer control unit from the diagnostic connector with a handle and take it with him.
