Abstract

The vehicle has a combined display unit in the vision area of the driver whilst at least some of this information can be displayed additionally in a second display unit (2) installed in the vehicle. The additional display need only be visible when there is a fault in the combination display unit (1). The display field of the second display unit can be used entirely or in part to show the substitute data.

Description

Stand der TechnikState of the art

Bei Kraftfahrzeugen werden die Fahrgeschwindigkeit und weitere für den Betrieb des Fahrzeuges notwendige Informationen in einem Kombiinstrument angezeigt, das direkt im Sichtfeld des Fahrzeugführers angeordnet ist. Ferner ist es bekannt, derartige Informationen dem Fahrzeugführer über ein optisches System, einen sogenannten Head-up-Display (HUD), in die Windschutzscheibe einzuspiegeln. Dieses umstrittene Anzeigesystem wird bei Kraftfahrzeugen aber nur selten angewandt. Die Signalaufbereitung für den HUD erfolgt in der Regel ebenfalls in einem Kombiinstrument.In motor vehicles, the driving speed and others necessary for the operation of the vehicle Information displayed in an instrument cluster that works directly is arranged in the driver's field of vision. Further is it is known to provide such information to the vehicle driver an optical system, a so-called head-up display (HUD) in the windshield. This controversial display system is only in motor vehicles rarely used. The signal processing for the HUD takes place usually also in an instrument cluster.

Fällt die Anzeige in einem Kombiinstrument durch Störung der Beleuchtung, der Zeigerantriebe, z. B. Schrittmotore, oder des zum Kombiinstrument gehörigen Rechners aus, so hat der Fahrzeugführer keine Information über die Fahrgeschwindigkeit mehr und kann sich auf Geschwindigkeitsbegrenzungen nicht mehr einstellen. Auch ist es nicht ungefährlich, wenn durch Ausfall des Kombiinstruments motorrelevante Anzeigen wie Öldruck und Motortemperatur oder Bremsflüssigkeitsstand nicht mehr verfügbar sind. Infolge der Komplexität der Kombiinstrumente ist deren Ausfallrate nicht vernachlässigbar. If the display falls in an instrument cluster due to malfunction Lighting, the pointer drives, e.g. B. stepper motors, or to the instrument cluster belonging to the instrument cluster Vehicle drivers no information about the driving speed more and cannot rely on speed limits set more. It is also not without danger if through Failure of the instrument cluster engine-related displays such as Oil pressure and engine temperature or brake fluid level are not are more available. Due to the complexity of the Instrument cluster is not their failure rate negligible.  

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, wenigstens die gefährlichsten Auswirkungen des störungsbedingten Ausfalls der Kombiinstrumente von Kraftfahrzeugen zu vermeiden.The invention is based, at least the task most dangerous effects of the failure-related failure to avoid the instrument cluster of motor vehicles.

Darstellung der ErfindungPresentation of the invention

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass wenigstens eine der für den Betrieb des Fahrzeugs wichtigen Informationen zusätzlich in einer zweiten im Fahrzeug eingebauten Anzeigevorrichtung anzeigbar ist. Anstelle einer ständig mitlaufenden zweiten Anzeige, die grundsätzlich auch möglich erscheint, wird, um die Anzeigevielfalt nicht ausufern zu lassen, vorgeschlagen, dass die zusätzliche Anzeige erst sichtbar wird, wenn in der kombinierten Anzeigevorrichtung eine Störung auftritt. Die zusätzliche Anzeige wird damit zur Ersatzanzeige. Als zusätzlich oder ersatzweise angezeigte Information kommt in erster Linie die Fahrgeschwindigkeit in Betracht, darüber hinaus aber auch weitere motor- oder fahrsicherheitsrelevante Informationen wie z. B. Öldruck, Motortemperatur, Bremsflüssigkeitsstand oder andere.This object is achieved in that at least one of those important for the operation of the vehicle Additional information in a second in the vehicle built-in display device can be displayed. Instead of one constantly running second ad, which in principle also appears to be possible, the display diversity is not to let it get out of hand, suggested that the additional Display only becomes visible when in the combined Display device malfunction occurs. The additional The advertisement becomes a replacement advertisement. As additional or information displayed as a substitute comes primarily from Driving speed into consideration, but also beyond further information relevant to the engine or driving safety such as B. oil pressure, engine temperature, brake fluid level or others.

Moderne Kraftfahrzeuge besitzen neben dem Kombiinstrument mehrere weitere Anzeigevorrichtungen mit Displayfeldern, insbesondere für Straßennavigation, Radio oder Klimaanlage. Diese weiteren Anzeigevorrichtungen sind mit dem Kombiinstrument über ein Bussystem, z. B. CAN (controlled area network) vernetzt. Der Erfindungsgedanke geht dahin, dass das Displayfeld einer solchen zweiten Anzeigevorrichtung vollständig oder in einem Teilbereich zur Darstellung der Ersatzanzeige herangezogen wird. Dies kann in der Weise geschehen, dass die ursprünglich auf diesem Displayfeld angezeigten Informationen durch die Ersatzanzeige unterdrückt oder von dieser überlagert werden. Es wird vorgeschlagen, dass die Ersatzanzeige optisch hervorgehoben ist, d. h. z. B. in einer auffälligen Farbe oder blinkend dargestellt wird.In addition to the instrument cluster, modern motor vehicles have several other display devices with display fields, especially for road navigation, radio or air conditioning. These other displays are with the Instrument cluster via a bus system, e.g. B. CAN (controlled area network) networked. The idea of the invention is that the Display field of such a second display device completely or in a partial area to represent the Replacement ad is used. This can be done in the way that happen originally on this display panel information displayed is suppressed by the replacement display  or be overlaid by this. It is suggested, that the replacement advertisement is optically highlighted, d. H. z. B. is shown in a striking color or flashing.

Wenn eines der genannten Elemente des Kombiinstruments gestört ist und dadurch insbesondere die Geschwindigkeitsanzeige ausfällt, so wird dieser Umstand mittels des Signals eines in solchen modernen Fahrzeugen vorhandenen Diagnosesystems an die zweite Anzeigevorrichtung gemeldet. Daraufhin kann das Geschwindigkeitssignal gegebenenfalls mit Hilfe einer in der zweiten Anzeigevorrichtung vorhandenen Ersatzrechnerfunktion sichtbar gemacht werden. Um auch den Fall abzudecken, dass der Rechner des Kombiinstruments ausfällt, müsste die zweite Anzeigevorrichtung als Bestandteil einen Ersatzrechner enthalten.If any of the elements of the instrument cluster mentioned is disturbed and in particular the Speed display fails, so this fact by means of the signal of one in such modern vehicles existing diagnostic system to the second display device reported. Then the speed signal if necessary with the help of one in the second Display device existing replacement computer function visible be made. To also cover the case that the calculator of the instrument cluster fails, the second Display device as part of a replacement computer contain.

Die zweite Anzeigevorrichtung kann aber auch, z. B. über CMI, das Geschwindigkeitssignal direkt von einem Antiblockiersystem (ABS) erhalten und zur Anzeige aufbereiten. Antiblockiersysteme gelten als sehr ausfallsicher, da in der Regel redundante Rechner eingesetzt werden.The second display device can also, for. B. via CMI, the speed signal directly from one Anti-lock braking system (ABS) received and for display Recycle. Anti-lock braking systems are considered very failsafe because redundant computers are usually used become.

Der Vorteil der Erfindung besteht also darin, dass dem Fahrzeugführer auch bei Auftreten der erwähnten Störungsfälle während der Fahrt jedenfalls die wichtigsten Anzeigen weiterhin zur Verfügung stehen.The advantage of the invention is that Vehicle driver even when the mentioned malfunctions occur the most important displays while driving continue to be available.

Ausführungsbeispielembodiment

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutert, die in schematischer Darstellung den typischen Aufbau eines Teils der elektronischen Anlage eines Kraftfahrzeugs zeigt. An embodiment of the invention is based on the Drawing explained, the schematic representation of the typical structure of part of an electronic system Motor vehicle shows.  

Ein Kombiinstrument 1 enthält mehrere Rundinstrumente, darunter den Fahrgeschwindigkeitsanzeiger. Ein Displayfeld 2, das z. B. zu einer Straßennavigations-Einrichtung, einem Radiogerät oder einer Klimaanlage gehört, dient als zweite Anzeigevorrichtung. Ein ABS-Gerät 3 liefert für alle Systeme das Geschwindigkeits- oder Wegsignal. Alle genannten Komponenten kommunizieren miteinander über eine Busleitung 4.An instrument cluster 1 contains several round instruments, including the vehicle speed indicator. A display field 2 , the z. B. belongs to a street navigation device, a radio or an air conditioner, serves as a second display device. An ABS device 3 provides the speed or distance signal for all systems. All of the components mentioned communicate with one another via a bus line 4 .

Tritt nun eine Störung im Kombiinstrument 1 auf, die eine Verfälschung oder den Ausfall der Geschwindigkeitsanzeige zur Folge hat, so ergeht ein Diagnosesignal an die das Displayfeld 2 enthaltende zweite Anzeigevorrichtung, wonach in dieser das vom ABS-Gerät 3 gelieferte Geschwindigkeitssignal gegebenenfalls bei gleichzeitigem Ausblenden oder einer Schwächung der Hauptanzeige so deutlich wie möglich angezeigt wird.If a fault now occurs in the instrument cluster 1 , which results in a falsification or failure of the speed display, a diagnostic signal is sent to the second display device containing the display field 2 , according to which the speed signal supplied by the ABS device 3 , if necessary, with simultaneous fading out or a weakening of the main display is shown as clearly as possible.
