Abstract

A device is disclosed which serves to calculate a motor vehicle servicing interval by referring to different detected or calculated operating values such as starting speed, crankshaft rotations, driving times and dwell times, engine temperature, engine oil pressure, charging air pressure, oil consumption, fuel consumption and the like. The evaluation of this data and the calculation of a servicing interval therefrom takes place by means of a computer (3) which as a result activates a corresponding display and/or outputs a servicing instruction in plain text in a visual and/or acoustic manner via corresponding means (4, 5). In addition, a device (7, 9) is provided which detects an engine oil filling process as such, if appropriate also in terms of quantity and reports this to the computer (3) which when calculating the servicing interval takes into account this information to the extent that the normal servicing interval is lengthened once by a defined time period or a defined mileage. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zur Berechnung eines Kraftfahrzeug-Wartungsintervalls.The invention relates to a device for calculating a motor vehicle maintenance interval.

Es ist bei verschiedenen derzeit auf dem Markt angebotenen Personenkraftfahrzeugen bekannt, mittels des Bordcomputers unter anderem auch die Kraftfahrzeugwartungsintervalle auf der Basis verschiedener erfaßter Betriebswerte zu berechnen. Eine Information hierüber wird für den Fahrer am Armaturenbrett in der Regel über eine Leuchtdiodenkette ausgegeben, wobei die Zunahme der aufleuchtenden Leuchtdioden als Indiz für die Notwendigkeit einer baldigen oder der nächsten Kraftfahrzeug-Inspektion dient. Auf diese Weise wird mithin mittels des Computers per eingespeichertem Programm immer ein bestimmtes Wartungsintervall berechnet. Äußere Einflußnahmen auf den Motor, z.B. vor Ablauf des errechneten Wartungsintervalls durchgeführte Maßnahmen, die letzteres an sich verlängern würden, bleiben dabei für den besagten Berechnungsvorgang ohne Einfluß, es sei denn, es wird durch den Wartungstechniker über das Diagnosegerät der dann angeschlossene Computer wieder auf den Start des betreffenden Rechenprogramms zurückgesetzt. Letzteres ist in vielen Fällen aber eine unzweckmäßige, wenn nicht gar unzulässige Maßnahme.In various passenger vehicles currently on the market, it is known to use the on-board computer to calculate, among other things, the vehicle maintenance intervals on the basis of various recorded operating values. Information about this is usually given to the driver on the dashboard via a light-emitting diode chain, the increase in the light-emitting diodes serving as an indication of the need for an early or the next motor vehicle inspection. In this way, a specific maintenance interval is therefore always calculated by means of the computer using a stored program. External influences on the engine, e.g. Measures carried out prior to the end of the calculated maintenance interval, which would extend the latter per se, have no influence on the said calculation process, unless the maintenance technician then resets the computer connected to the start of the relevant computer program via the diagnostic device. In many cases, the latter is an inappropriate, if not impermissible, measure.

Es ist daher Aufgabe der Erfindung, eine Vorrichtung zur Berechnung eines Kraftfahrzeug-Wartungsintervalles so zu gestalten, daß eine einwandfreie Ermittlung desselben auch dann möglich ist, wenn vor dessen Ablauf bestimmte Wartungsmaßnahmen im Fahrzeug durchgeführt werden.It is therefore an object of the invention to design a device for calculating a motor vehicle maintenance interval in such a way that it can also be correctly determined if certain maintenance measures are carried out in the vehicle before it expires.

Diese Aufgabe ist erfindungsgemäß durch eine Vorrichtung mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen derselben sind in den Unteransprüchen angegeben.This object is achieved by a device with the features specified in claim 1. Advantageous refinements of the same are specified in the subclaims.

Mit der erfindungsgemäßen Vorrichtung ist es somit einerseits möglich, ein Wartungsintervall exakt zu berechnen und dem Fahrer die Notwendigkeit einer Fahrzeuginspektion anzuzeigen. Andererseits ist es mit der erfindungsgemäßen Vorrichtung möglich, das solcher maßen berechnete Wartungsintervall einmalig immer dann um einen definierten Zeitraum bzw. eine definierte Kilometerleistung des Fahrzeugs zu verlängern, d.h. den nächsten Inspektionszeitpunkt hinauszuschieben, wenn vorher ein Motoröl-Nachfüllvorgang stattgefunden hat. Dieser für zulässig erachteten Möglichkeit liegt die Erkenntnis zugrunde, daß eine partielle Erneuerung des ge- bzw. verbrauchten Motoröles zwar keinen Optimalzustand herbeiführt, trotzdem, aber einen noch ausreichend sicheren Motorbetrieb gewährleistet. Insbesondere im gütertransportierenden Lkw-Fernverkehr ist es somit möglich, einen oder mehrere dringende Aufträge noch zuverlässig abwickeln zu können, bis der betreffende Lastkraftwagen dann endgültig zur Inspektion gebracht wird. Mit anderen Worten: Es wird der Fahrer durch eine solche automatische einmalige Verlängerung des normalen Wartungsintervalles nicht in Gewissensnöte gebracht, bei Aufleuchten der entsprechenden Anzeige während einer z.B. ins Ausland führenden Frachttour nun unbedingt schon dort die an sich notwendigen Wartungsmaßnahmen durchführen zu müssen. Vielmehr genügt die Motorölnachfüllung oder der partielle Ersatz des verbrauchten Öles, um ohne Not den heimatlichen Standort zu erreichen.With the device according to the invention it is thus possible on the one hand to exactly calculate a maintenance interval and to indicate to the driver the need for a vehicle inspection. On the other hand, it is possible with the device according to the invention to calculate the maintenance interval calculated in such a way once every time by a defined period or a defined mileage to extend the vehicle, ie to postpone the next inspection time if an engine oil refilling process has previously taken place. This possibility, which is considered to be permissible, is based on the knowledge that partial renewal of the used or used engine oil does not bring about an optimal condition, but nevertheless ensures an adequately safe engine operation. In long-haul trucking in particular, it is therefore possible to reliably process one or more urgent orders until the truck in question is finally brought for inspection. In other words, such an automatic one-time extension of the normal maintenance interval does not put the driver in a state of conscience, so that the relevant maintenance measures have to be carried out there when the corresponding display lights up during a freight tour leading abroad, for example. Rather, the engine oil refill or the partial replacement of the used oil is enough to reach the home location without need.

Nachstehend ist die erfindungsgemäße Lösung im Prinzip anhand der in der Zeichnung dargestellten Skizze noch näher erläutert.The solution according to the invention is explained in more detail below in principle on the basis of the sketch shown in the drawing.

In der Zeichnung ist mit 1 der Verbrennungsmotor und mit 2 die zugehörige Ölwanne eines Kraftfahrzeuges bezeichnet. Mit 3 ist ein fahrzeuginterner Computer bezeichnet, bei dem es sich um ein eigenständiges Bauteil oder den heute in Fahrzeugen vielfach schon vorhandenen Bordcomputer handeln kann, der den Motorbetrieb, gegebenenfalls auch die Getriebeeinstellung und Kupplungsbetätigung und andere Funktionen des Fahrzeugs steuert. Der Computer 3 hat den üblichen Aufbau mit Ein-und Ausgabeeinheiten, Daten- und Programmspeichern und Mikroprozessor, welche Komponenten über ein BUS-System miteinander verknüpft sind.In the drawing, 1 denotes the internal combustion engine and 2 the associated oil pan of a motor vehicle. 3 with an in-vehicle computer is referred to, which can be an independent component or the on-board computer that is often already present in vehicles today and which controls the engine operation, possibly also the transmission setting and clutch actuation and other functions of the vehicle. The computer 3 has the usual structure with input and output units, data and program memories and a microprocessor, which components are linked to one another via a BUS system.

Dem Computer 3 werden mittels Sensoren oder anderer Erfassungsorgane ermittelte Betriebswerte bzw. Daten,wie die Anzahl der Starts bzw. Motoranlassungen (St), Anzahl der Kurbelwellenumdrehungen (Kw), Fahrzeiten (tF) und Standzeiten (tSt) des Fahrzeugs, Motortemperatur (tMot), Motoröldruck (PÖl), Ladeluftdruck (PLL), Ölstand (9), Kraftstoffverbrauch (Kr) und dergleichen, in Form elektrischer Signale zugeleitet. Aus diesen Betriebswerten bzw. Daten errechnet der Computer 3 per eingespeichertem Programm ein Wartungsintervall. Abhängig vom Ergebnis gibt der Computer 3 z.B. über eine Leuchtdioden-Kette 4 und/oder ein Digitaldisplay 5 am Armaturenbrett eine entsprechende Information an den Fahrer aus, wobei der Fahrer beispielsweise bei Aufleuchten der ersten Leuchtdiode auf den Beginn einer Frist bis zur nächsten Fahrzeuginspektion und mit Aufleuchten weiterer Leuchtdioden auf den zunehmenden Auflauf dieser Frist aufmerksam gemacht wird. Mittels des Digitaldisplays 5 kann dem Fahrer zusätzlich oder ausschließlich eine Information über den Zeitpunkt der nächsten Inspektion und/oder über eine durchzuführende Wartungsmaßnahme gegeben werden. Bei Durchführung der Fahrzeuginspektion erfolgt die Kontrolle in der Regel über ein am Computer 3 anzuschließendes elektronisches Diagnosegerät 6, mit dem nach Durchführung der erforderlichen Wartungsarbeiten in der Regel auch das Programm für die Berechnung des nächsten Wartungsintervalles gestartet wird.The computer 3 receives operating values or data determined by means of sensors or other detection elements, such as the number of starts or engine starts (St), number of crankshaft revolutions (Kw), driving times (t F ) and downtimes (t St ) of the vehicle, engine temperature ( t Mot ), engine oil pressure (P oil ), charge air pressure (P LL ), oil level (9), fuel consumption (Kr) and the like, in the form of electrical signals. From these operating values or data, the computer 3 calculates a maintenance interval using a stored program. Depending on the result the computer 3 outputs corresponding information to the driver, for example via a light-emitting diode chain 4 and / or a digital display 5 on the dashboard, the driver, for example, when the first light-emitting diode lights up for the start of a period until the next vehicle inspection and when further light-emitting diodes light up attention is drawn to the increasing accumulation of this period. Using the digital display 5, the driver can additionally or exclusively be given information about the time of the next inspection and / or about a maintenance measure to be carried out. When the vehicle inspection is carried out, the control is generally carried out via an electronic diagnostic device 6 to be connected to the computer 3, with which the program for the calculation of the next maintenance interval is generally also started after the required maintenance work has been carried out.

Darüber hinaus ist eine Vorrichtung vorgesehen, die einen Motoröl-Nachfüllvorgang als solches, gegebenenfalls auch mengenmäßig erfaßt. Hierzu ist beispielsweise ein Durchflußsensor vorgesehen, der an geeigneter Stelle im Öleinfüllstutzen 8 ein- bzw. angebaut ist. Der Durchflußsensor 7 erfaßt eine Motorölnachfüllung, kann jedoch auch als die Öldurchflußmenge erfassendes Durchflußmeßorgan ausgebildet sein. Eine Erfassung der nachgefüllten Motorölmenge kann aber auch über den in die Ölwanne 2 eingebauten Ölstandsmesser 9 erfolgen. Die erfaßten Zustände werden an den Computer 3 in Form elektrischer Signale gemeldet.In addition, a device is provided which detects an engine oil refilling process as such, possibly also in terms of quantity. For this purpose, a flow sensor is provided, for example, which is installed or attached at a suitable point in the oil filler neck 8. The flow sensor 7 detects an engine oil refill, but can also be designed as a flow measuring element that detects the oil flow rate. The amount of engine oil refilled can also be recorded via the oil level meter 9 installed in the oil pan 2. The detected states are reported to the computer 3 in the form of electrical signals.

Falls dem Computer 3 nun vor Ablauf eines berechneten Wartungsintervalles von den Erfassungsorganen 7, 9 ein Motorölnachfüllvorgang signalisiert wird, interpretiert und berücksichtigt dieser diese Information bei der Berechnung des Wartungsintervalles in dem Sinne, daß das normale, sich auf der Basis der weiter vorn bereits erwähnten Betriebswerte bzw. -daten ergebende Wartungsintervall einmalig im einen definierten Zeitraum bzw. eine definierte noch zurückzulegende Kilometerleistung (Fahrstrecke) verlängert und demzufolge an den Fahrer dann auch erst zu einem späteren Zeitpunkt die Information für die folgende Fahrzeuginspektion über die Anzeigemittel 4,5 ausgegeben wird. Es sei diesbezüglich darauf hingewiesen, daß diese Information des Fahrers auch über andere als die in der Zeichnung aufgezeigten Mittel 4, 5, z.B. auch oder nur akustisch ausgegeben werden kann.If the computer 3 now signals an engine oil refilling process before the end of a calculated maintenance interval, it interprets and takes this information into account when calculating the maintenance interval in the sense that the normal value is based on the operating values already mentioned above The maintenance interval or data resulting from this is extended once in a defined period of time or a defined mileage (distance traveled) to be covered and, consequently, the information for the subsequent vehicle inspection is then only output to the driver at a later point in time via the display means 4, 5. In this regard, it should be pointed out that this information of the driver is also provided by means 4, 5 other than those shown in the drawing, e.g. can also or only be output acoustically.
