Abstract

The invention relates to a method for protecting a starter of an engine of a motor vehicle, especially of an engine having a stop/start functionality. According to the invention, an engine speed and/or a vehicle speed is detected during a starter mode for starting the engine and the starter mode is stopped if the increase of the detected engine speed gradually falls below a predetermined value or the detected vehicle speed exceeds a predetermined value.

Description

Verfahren und eine Vorrichtung zum Schutz eines Starters eines Kraftfahrzeugmotors Method and device for protecting a starter of a motor vehicle engine
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Schutz eines Starters eines Motors eines Kraftfahrzeugs, insbesondere eines Motors mit einer Stopp/Start-Funktionalität.The invention relates to a method and a device for protecting a starter of an engine of a motor vehicle, in particular of a motor with a stop / start functionality.
Moderne Motorsteuerungen von Kraftfahrzeugen beinhalten verschiedene Maßnahmen zur Steuerung eines Starters (Startermotors) zum Starten eines mit diesem über einen Kupplungsmechanismus verbindbaren Motors (Verbrennungsmotors) . Solche Maßnahmen sind insbesondere bei Kraftfahrzeugmotoren mit einer Stopp/Start-Funktionalität von Bedeutung, bei welcher der Motor beim Anhalten des Kraftfahrzeugs zum Beispiel an einer Verkehrsampel automatisch ausgeschaltet wird und bei einem anschließenden Anfahrwunsch des Fahrers (erkennbar z.B. durch eine Betätigung des Gaspedals) über den Starter automatisch wieder gestartet wird.Modern motor controls of motor vehicles include various measures for controlling a starter (starter motor) for starting a connectable to this via a clutch mechanism engine (internal combustion engine). Such measures are particularly important in motor vehicle engines with a stop / start functionality in which the engine is automatically turned off when stopping the motor vehicle, for example, at a traffic light and at a subsequent approach of the driver (recognizable, for example, by pressing the accelerator pedal) on the Starter automatically restarts.
So beschreibt zum Beispiel die EP 0 526 985 A2 einen Kraftfahrzeugmotor mit einer Startsperrfunktion, die immer dann aktiviert wird, wenn keine für einen Start des Motors durch den Starter sicheren Bedingungen vorherrschen. Sichere Startbedingungen sind in diesem Fall eine neutrale Stellung des Getriebes und eine Nichtbetätigung der Kupplung. Um zu vermeiden, dass ein Starterbetrieb abgebrochen wird, weil die Batteriespannung durch den Betrieb des Starters stark abfällt und dies als ein ungeeigneter Startzustand beurteilt werden könnte, wird die Startsperrfunktion außer Kraft gesetzt, wenn eine sichere Startbedingung einmal erkannt worden ist und daraufhin der Starterbetrieb begonnen hat.Thus, for example, EP 0 526 985 A2 describes an automotive engine with a start-lock function which is activated whenever there are no conditions that are safe for a start of the engine by the starter. Safe starting conditions are in this case a neutral position of the transmission and a non-actuation of the clutch. To avoid that a starter operation is canceled, because the Battery voltage due to the operation of the starter drops sharply and this could be judged to be an inappropriate start condition, the start disable function is overridden when a safe start condition has been detected once and then the starter operation has started.
Die EP 1 201 479 Bl offenbart eine Startervorrichtung für einen Kraftfahrzeugmotor, bei der eine Kraftstoffzufuhr zum angedrehten Motor erst dann erfolgt, nachdem ein Kupplungsmechanismus zwischen Starter und Motor nach einer Drehzahl- synchronisierung dieses Kupplungsmechanismus geschlossen ist, um Kraftstoff einzusparen.EP 1 201 479 B1 discloses a starter device for an automotive engine in which a fuel supply to the engine turned off only after a clutch mechanism between the starter and engine after a speed synchronization of this clutch mechanism is closed to save fuel.
Weiter ist aus der DE 103 43 400 Al eine spezielle Momenten- übertragungsanordnung zwischen einem Startermotor und einer Kurbelwelle eines Kraftfahrzeugmotors bekannt, die eine Trennung des Startermotors bei Erreichen einer Grenzdrehzahl ermöglicht, um so den Startermotor zu schonen.Furthermore, DE 103 43 400 A1 discloses a special torque transmission arrangement between a starter motor and a crankshaft of a motor vehicle engine, which makes it possible to separate the starter motor when a limiting rotational speed is reached so as to protect the starter motor.
Die vorgenannten herkömmlichen Motorsteuerungen befassen sich mit der Steuerung des Betriebs eines Starters zum Andrehen eines Verbrennungsmotors, offenbaren aber keinerlei Schutzmaßnahmen gegen eine Fehlbedienung des Kraftfahrzeugs bzw. Starters durch den Fahrer während eines Motorstarts durch den Starter. So besteht insbesondere bei einem Kraftfahrzeugmotor mit Stopp/Start-Funktionalität zum Beispiel die Möglichkeit, dass der Fahrer beim Starten des Motors aus einer Stoppphase des Motors heraus die Kupplung zu schnell kommen lässt und dadurch das Kraftfahrzeug bis zu einem gewissen Grad mit Hilfe des Starters (Startermotors) in Bewegung setzt (was bei einem normalen Anfahrvorgang ein Abwürgen des Motors zur Folge haben würde) . Da ein Starter aufgrund seiner Bauart sehr schnell überlasten kann, besteht Bedarf an einem System, das den beschriebenen Fall einer Fehlbedienung sicher ausschließen kann.The aforementioned conventional engine controls are concerned with the control of the operation of a starter for starting an internal combustion engine, but do not disclose any protective measures against an erroneous operation of the motor vehicle or starter by the driver during an engine start by the starter. Thus, for example, in the case of a motor vehicle engine with stop / start functionality, there is the possibility that the driver may override the clutch too quickly when starting the engine from a stop phase of the engine and thereby to a certain extent use the starter (FIG. Starter motor) in motion (which would result in a normal starting process, a stalling of the engine). Since a starter can overload very quickly due to its design, there is a need for a system which can safely exclude the described case of incorrect operation.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren und eine Vorrichtung zum Schutz eines Starters eines Kraftfahrzeugmotors zu schaffen, mit denen ein Starter gegen eine Fehlbedienung des Starters bzw. Kraftfahrzeugs der oben beschriebenen Art durch einen Fahrer ausreichend geschützt ist.The object of the present invention is therefore to provide a method and a device for protecting a starter of a motor vehicle engine, with which a starter is sufficiently protected against incorrect operation of the starter or motor vehicle of the type described above by a driver.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 bzw. eine Vorrichtung mit den Merkmalen des Anspruchs 2 gelöst.This object is achieved by a method having the features of claim 1 and a device having the features of claim 2.
Das Verfahren zum Schutz eines Starters eines Motors eines Kraftfahrzeugs ist gekennzeichnet durch die Schritte des Erfassens einer Motordrehzahl und/oder einer Fahrzeuggeschwindigkeit während eines Starterbetriebs zum Starten des Motors und des Stoppens des Starterbetriebs, falls ein Anstieg der erfassten Motordrehzahl mit der Zeit unter einen vorbestimmten Wert fällt bzw. die erfasste Fahrzeuggeschwindigkeit einen vorbestimmten Wert übersteigt.The method for protecting a starter of an engine of a motor vehicle is characterized by the steps of detecting an engine speed and / or a vehicle speed during a starter operation for starting the engine and stopping the starter operation if an increase in the detected engine speed with time is below a predetermined value falls or the detected vehicle speed exceeds a predetermined value.
Die Vorrichtung zum Schutz eines Starters eines Motors eines Kraftfahrzeugs enthält eine Erfassungseinrichtung zum Erfassen einer Motordrehzahl und/oder einer Fahrzeuggeschwindigkeit; eine Beurteilungseinrichtung zum Beurteilen, ob ein Anstieg einer erfassten Motordrehzahl mit der Zeit unter einen vorbestimmten Wert fällt bzw. eine erfasste Fahrzeuggeschwindigkeit einen vorbestimmten Wert übersteigt; und eine Ausgabeeinrichtung zum Ausgeben eines Betriebsstoppsignals zum Stoppen des Betriebs des Starters, falls die Beurteilungseinrichtung während eines Starterbetriebs zum Starten des Motors beurteilt, dass ein Anstieg der erfassten Motordrehzahl unter den vorbestimmten Wert fällt bzw. die erfasste Fahrzeuggeschwindigkeit den vorbestimmten Wert übersteigt .The device for protecting a starter of an engine of a motor vehicle includes a detection device for detecting an engine speed and / or a vehicle speed; judgment means for judging whether an increase of a detected engine speed with time falls below a predetermined value or a detected vehicle speed exceeds a predetermined value; and an output means for outputting an operation stop signal for stopping the operation of the starter, if the judging means judges, during a starter operation for starting the engine, that an increase in detected Engine speed falls below the predetermined value or the detected vehicle speed exceeds the predetermined value.
Dieses Verfahren und diese Vorrichtung sind in besonders vorteilhafter Weise bei einem Kraftfahrzeug mit einer Stopp/ Start-Funktionalität des Motors anwendbar.This method and apparatus are particularly advantageously applicable to a motor vehicle having stop / start functionality of the engine.
Die vorliegende Erfindung beruht auf der Erkenntnis, dass sich, falls ein Fahrer beim Start des Verbrennungsmotors die Kupplung zu schnell kommen lässt, dies in einem verzögerten Drehzahlanstieg des Motors und einem messbaren Geschwindigkeitssignal des Kraftfahrzeugs zeigt. Dieses Verhalten weicht von dem eines regulären Motorstarts ab und kann daher eindeutig erkannt und in der Motorsteuerung verarbeitet werden.The present invention is based on the recognition that, if a driver at the start of the engine, the clutch can come too fast, this shows in a delayed speed increase of the engine and a measurable speed signal of the motor vehicle. This behavior deviates from that of a regular engine start and can therefore be clearly recognized and processed in the engine control.
In der Motorsteuerung werden aus diesem Grund während eines Starterbetriebs zum Starten des Motors eine Motordrehzahl und/oder eine Fahrzeuggeschwindigkeit erfasst. Der Starterbetrieb wird dann gestoppt, falls ein Anstieg der erfassten Motordrehzahl mit der Zeit unter einen vorbestimmten Wert fällt bzw. die erfasste Fahrzeuggeschwindigkeit einen vorbestimmten Wert übersteigt.In the engine controller, for this reason, during a starting operation for starting the engine, an engine speed and / or a vehicle speed are detected. The starter operation is then stopped if an increase in the detected engine speed over time falls below a predetermined value or the detected vehicle speed exceeds a predetermined value.
Durch diese Schutzmaßnahme kann der Fahrer das Kraftfahrzeug zwar nicht mehr starterunterstützt anfahren, da er in diesem Fall ein Abwürgen des Verbrennungsmotors provoziert, um den Starter optimal vor einer Beschädigung (durch Überlastung) zu schützen. Voraussetzung für den verbesserten Starterschutz ist eine Erfassung von Kurbelwinkel (für Motordrehzahl) und Raddrehzahl (für Fahrzeuggeschwindigkeit) mit einer ausreichend hohen Auflösung. Der erfindungsgemäß optimierte Starterschutz durch die zusätzlichen Funktionen, die vorzugsweise in der Motorsteuerung selbst implementiert sind, findet in besonders vorteilhafter Weise Anwendung bei einem Kraftfahrzeug mit einem Motor mit Stopp/Start-Funktionalität . Through this protective measure, the driver can no longer approach the motor vehicle starterunterstützt, as he provoked in this case, a stalling of the engine to optimally protect the starter from damage (by overloading). Prerequisite for the improved starter protection is a detection of crank angle (for engine speed) and wheel speed (for vehicle speed) with a sufficiently high resolution. The inventively optimized starter protection by the additional functions, which are preferably implemented in the engine control itself, is used in a particularly advantageous manner in a motor vehicle with an engine with stop / start functionality.
