Description
Die Erfindung bezieht sich auf ein Verfahren zum Steuern eines Antriebssystems in einem Kraftfahrzeug nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a method for controlling a drive system in a motor vehicle according to the preamble of patent claim 1.
Ein
derartiges Verfahren ist beispielsweise aus der
Es ist Aufgabe der Erfindung, ein Verfahren zum Steuern eines Antriebssystems eingangs genannter Art im Hinblick auf eine Komfortoptimierung zu verbessern.It The object of the invention is a method for controlling a drive system initially mentioned type in terms of comfort optimization too improve.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des unabhängigen Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind die Gegenstände der abhängigen Patentansprüche.These The object is achieved by the Characteristics of the independent Patent claim 1 solved. Advantageous developments are the subject matters of the dependent claims.
Bei dem erfindungsgemäßen Verfahren zum Steuern eines Antriebssystems in einem Kraftfahrzeug mit mindestens einem elektronischen Steuergerät, das als Eingangssignal die Fahrpedalstellung und weitere Betriebsparameter erfasst und abhängig von der Fahrpedalstellung und weiteren Betriebsparametern eine vom Fahrer gewünschte Soll-Leistung ermittelt, erfasst das Steuergerät zumindest die Fahrpedalbetätigungsgeschwindigkeit, mit der die Fahrpedalstellung von einem Wert über Null auf Null übergeht. Bei Erreichen der Fahrpedalstellung Null wird die Soll-Leistung bzw. eine der Soll-Leistung proportionale Größe wie beispielsweise das Soll-Radmoment in Form einer negativen Leistung bzw. in Form eines negativen Radmoments (Schleppmoment) auf Null begrenzt, wenn die Fahrpedalbetätigungsgeschwindigkeit kleiner als ein vorgegebener Schwellwert war.at the method according to the invention for controlling a drive system in a motor vehicle with at least an electronic control unit, as the input signal the accelerator pedal position and other operating parameters captured and dependent on the accelerator pedal position and other operating parameters one by the driver desired Determines desired power, the control unit detects at least the accelerator pedal actuation speed, with which the accelerator pedal position changes from a value above zero to zero. When reaching the accelerator pedal position zero, the target power or a variable power proportional to the target power such as the target wheel torque in the form of a negative power or in the form of a negative wheel torque (Drag torque) is limited to zero when the accelerator pedal actuation speed was less than a predetermined threshold.
Weiter kann allgemein das Schleppmoment bei Erreichen der Fahrpedalstellung Null im Bereich zwischen einem Schleppmoment von Null und einem minimal möglichen Schleppmoment abhängig von der Fahrpedalbetätigungsgeschwindigkeit vorgegeben werden.Further can generally the drag torque when reaching the accelerator pedal position Zero in the range between a drag torque of zero and a minimum potential Drag torque dependent from the accelerator operation speed be specified.
Ausgehend von dem der Fahrpedalstellung Null neu zugeordneten Schleppmoment kann die gesamte Kennlinie, die jeder möglichen Fahrpedalstellung jeweils eine Soll-Leistung bzw. ein Soll-Radmoment zuordnet, entsprechend angepasst werden.outgoing from the accelerator pedal position zero newly assigned drag torque can be the entire characteristic curve of each possible accelerator pedal position respectively assigns a desired power or a desired wheel torque, accordingly be adjusted.
Der
Erfindung liegt folgende Erkenntnis zugrunde:
Durch das erfindungsgemäße Verfahren
soll eine Steuerungsstrategie für
Antriebssysteme in Kraftfahrzeugen geschaffen werden, mit der situationsabhängig die
vom Antriebsstrang aufzunehmende Schleppleistung bei beliebiger
Fahrpedalstellung, insbesondere aber in der Ruhestellung des Fahrpedals,
so zu variieren, dass bestmöglicher
Komfort bei gleichzeitiger Berücksichtigung
weitere Anforderungen erreicht wird. Im Vordergrund steht die Verhinderung
unkomfortabler Lastwechselschläge
durch den Vorzeichenwechsel des Antriebsmoments bzw. der Leistung
(Schleppmoment bzw. Schleppleistung (negativ)/Zugmoment bzw. Zugleistung
(positiv)). Aber es sollen auch keine unerwünschten Eigenlenkreaktionen
des Fahrzeuges beispielsweise unter kritischen Reibwertbedingungen
auftreten. Auch soll, wenn möglich,
die Betriebsbremse entlastet werden.The invention is based on the following finding:
By the method according to the invention, a control strategy for drive systems in motor vehicles is to be created with the situation depending on the driveline absorbed towing power at any accelerator pedal position, but especially in the rest position of the accelerator pedal to vary so that the best possible comfort while taking into account other requirements. In the foreground is the prevention of uncomfortable load changes due to the sign change of the drive torque or the power (drag torque or towing power (negative) / tensile torque or tensile power (positive)). But it should also occur no unwanted self-steering reactions of the vehicle, for example, under critical Reibwertbedingungen. Also, if possible, the service brake should be relieved.
Mittels
der in der Zeichnung dargestellten Kennlinien soll das durch ein
elektronisches Steuergerät
durchgeführte
erfindungsgemäße Verfahren näher erläutert werden:
Das
hier nicht dargestellte elektronische Steuergerät, beispielsweise ein ohnehin
vorhandenes Brennkraftmaschinensteuergerät und/oder Automatikgetriebesteuergerät, erhält als Eingangssignal
die Fahrpedalstellung FP (in Prozent zwischen 0% und 100%) und weitere
Informationen, wie zum Beispiel das Vorliegen von Radschlupf, die
Betätigung
der Betriebsbremse und/oder eine Anforderung zur Krafstoffverbrauchseinsparung.
Entsprechend abgespeicherter Kennlinien bzw. Kennfelder ermittelt
das Steuergerät abhängig von
der Fahrpedalstellung FP und gegebenenfalls weiteren Betriebsparametern
eine vom Fahrer gewünschte
Soll-Leistung bzw. ein Soll-Radmoment Mrad- soll.By means of the characteristic curves shown in the drawing, the method according to the invention carried out by an electronic control unit will be explained in more detail:
The electronic control unit, not shown here, for example, an already existing engine control unit and / or automatic transmission control unit receives as input the accelerator pedal position FP (in percent between 0% and 100%) and other information, such as the presence of wheel slip, the operation of the service brake and / or a requirement to save fuel. In accordance with stored characteristic curves or characteristic maps, the control unit determines, depending on the accelerator pedal position FP and possibly further operating parameters, a desired power desired by the driver or a desired wheel torque M rad- soll .
Die
Kennlinie
Das
Steuergerät
erfasst die Fahrpedalbetätigungsgeschwindigkeit
dFP/dt, mit der die Fahrpedalstellung FP von einem Wert größer 0% auf
0% (Ruhestellung) übergeht.
Bei Erreichen der Fahrpedalstellung Null (0%) wird die Soll-Leistung
in Form eines negativen Soll-Radmoments Mrad-soll (Schleppmoment)
auf 0 [Nm] begrenzt, wenn die Fahrpedalbetätigungsgeschwindigkeit dFP/dt
kleiner als ein vorgegebener Schwellwert war (maximale Begrenzung). Dadurch
ergibt sich beispielsweise die in der Zeichnung dargestellte Kennlinie
Ausgehend
von dem der Fahrpedalstellung Null neu zugeordneten Schleppmoment
kann also die gesamte Kennlinie, die jeder möglichen Fahrpedalstellung jeweils
eine Soll-Leistung bzw. ein Soll-Radmoment zuordnet, entsprechend
angepasst werden. Beispielsweise kann hierfür also eine Kennlinie von einer
Fahrpedalstellung von Null (0%) bis zur maximal möglichen
Fahrpedalstellung (100%) zwischen dem der Fahrpedalstellung Null
jeweils neu zugeordneten Schleppmoment und einem der maximalen Fahrpedalstellung
(100%) zugeordneten insbesondere maximalen Schleppmoment Mmax linearisiert werden, wie beispielsweise
die Kennlinien
Vorzugsweise
erhält
das Steuergerät
eine Information über
das Vorliegen von Radschlupf und begrenzt bei Vorliegen von Radschlupf
das Schleppmoment unabhängig
von der Fahrpedalbetätigungsgeschwindigkeit
dFP/dt. Beispiele hierfür
sind mit den alternativen Kennlinien
Liegt im Steuergerät eine Anforderung zur Erhöhung des Komforts vor, wird vorzugsweise ebenfalls das Schleppmoment unabhängig von der Fahrpedalbetätigungsgeschwindigkeit dFP/dt begrenzt.Lies in the control unit a request to increase comfort, is preferably also the drag torque independently from the accelerator operation speed dFP / dt limited.
Das Steuergerät nimmt jedoch vorzugsweise keine Begrenzung des Schleppmoments vor, wenn innerhalb eines vorgegebenen Zeitfensters nach Erreichen der Fahrpedalstellung 0% die Bremse betätigt wird.The control unit however preferably does not limit the drag torque, if within a given time window after reaching the Accelerator pedal position 0% the brake is applied.
Ebenso nimmt das Steuergerät keine Begrenzung des Schleppmoments vor, wenn bei Erreichen der Fahrpedalstellung 0% Bergabfahrt erkannt wird und somit eine erhöhte Bremsleistung aus Sicherheitsgründen oder sonstigen Gründen erforderlich ist.As well takes the control unit no limitation of the drag torque, when reaching the Accelerator pedal position 0% downhill is detected and thus increased braking power for safety reasons or other reasons is required.
Ebenso nimmt das Steuergerät keine Begrenzung des Schleppmoments vor, wenn einer Anforderung zur Reduzierung des Kraftstoffverbrauchs der Vorrang gegenüber einer Komfortanforderung erteilt wird.As well takes the control unit no limitation of the drag torque when making a request to reduce fuel consumption takes precedence over one Comfort request is issued.
