Die Steuerungsvorrichtung ist konfiguriert, um einen Ausgabewert des Motorgenerators so zu steuern, dass eine Drehgeschwindigkeit der Antriebsmaschine mit einer Soll-Drehgeschwindigkeit der Antriebsmaschine konvergiert. Die Steuerungsvorrichtung umfasst eine Steuerungseinrichtung zum Berechnen eines geschätzten Werts der Antriebskraft der Antriebsmaschine, die durch den Planetengetriebemechanismus verloren geht, und zum Berechnen des Ausgabewerts des Motorgenerators im Ansprechen auf den geschätzten Wert.A control device for a hybrid vehicle is provided. An engine is configured to output a driving force. A planetary gear mechanism is coupled to the prime mover. A motor generator is coupled to the planetary gear mechanism. The prime mover and the motor generator are coupled to an output shaft via the planetary gear mechanism. The control device is configured to control an output value of the motor generator so that a rotational speed of the prime mover converges to a target rotational speed of the prime mover. The control device includes control means for calculating an estimated value of the driving force of the engine, which is lost by the planetary gear mechanism, and calculating the output value of the motor generator in response to the estimated value.
Description
Technisches Gebiet der ErfindungTechnical field of the invention
Die vorliegende Erfindung bezieht sich im Allgemeinen auf eine Steuerungsvorrichtung für ein Hybridfahrzeug, und insbesondere auf eine Steuerungsvorrichtung für ein Hybridfahrzeug, das mit einer Antriebsmaschine und einem Motorgenerator ausgerüstet ist.The present invention generally relates to a control device for a hybrid vehicle, and more particularly to a control device for a hybrid vehicle equipped with an engine and a motor generator.
Hintergrund der ErfindungBackground of the invention
Es ist ein Hybridfahrzeug bekannt, in welchem eine Antriebskraft von einer Antriebsmaschine und Antriebskräfte von ersten und zweiten Motorgeneratoren auf Antriebsräder über erste und zweite Planetengetriebemechanismen übertragen werden. Eine solche Steuerungsvorrichtung für ein Hybridfahrzeug ist z. B. in Patentschrift 1 und Patentschrift 2 offenbart.

Japanese Patent Application Publication No. 2012-171593A
In einem in Patentschrift 1 offenbarten Hybridfahrzeug und einem Steuerungsverfahren desselben umfasst das Hybridfahrzeug einen Energieverteilungs-Integrationsmechanismus (Planetengetriebemechanismen PG1/PG2), mit welchem eine Antriebsmaschine und ein erster Motorgenerator MG1 gekoppelt sind, um die Antriebskraft von der Antriebsmaschine und dem ersten Motorgenerator MG1 zu Antriebsrädern zu übertragen, und einen Geschwindigkeitsreduzierer, mit welchem ein zweiter Motorgenerator MG2 gekoppelt ist, um die Antriebskraft von dem zweiten Motorgenerator MG2 zu den Antriebsrädern zu übertragen. Das Steuerungsverfahren steuert den ersten und zweiten Motorgenerator MG1 und MG2, so dass eine zu einer Ausgangswelle übertragene Antriebskraft einen Sollwert gemäß einem Betriebszustand der Antriebsmaschine aufweist.In a hybrid vehicle disclosed in
In Patentschrift 1 wird, wenn der Ausgabewert des zweiten Motorgenerators MG2 auf etwa Null gesteuert wird, die Richtung eines bezüglich des zweiten Motorgenerator MG2 auftretenden Drehmoments zu positiven/negativen Werten umgekehrt, wodurch möglicherweise von dem Geschwindigkeitsreduzierer oder dergleichen ein Rauschen erzeugt wird. In diesem Fall wird der zweite Motorgenerator MG2 gesteuert, um den Ausgabewert aufzuweisen, der außerhalb des Bereichs von etwa Null liegt.In
In einem in Patentschrift 2 offenbarten Hybridfahrzeug wird eine Soll-Drehgeschwindigkeit einer Antriebsmaschine im Ansprechen auf eine resultierende Drehgeschwindigkeit einer Ausgangswelle, an welcher ein Antriebsrad angebracht ist, eingestellt, um eine gewünschte Drehgeschwindigkeit der Ausgangswelle zu erhalten. Ferner wird ein Drehmoment eines Motorgenerators gesteuert (sogenannte Rückkopplungssteuerung) im Ansprechen auf eine Differenz zwischen einer Drehgeschwindigkeit der Antriebsmaschine und der Soll-Drehgeschwindigkeit der Antriebsmaschine, so dass die Drehgeschwindigkeit der Antriebsmaschine die Soll-Drehgeschwindigkeit der Antriebsmaschine erreicht.In a hybrid vehicle disclosed in
Allerdings werden gemäß der Steuerungsvorrichtung für ein Hybridfahrzeug des Stands der Technik, wenn sich die Drehgeschwindigkeit der Ausgangswelle der Soll-Drehgeschwindigkeit nähert, der jeweils mit dem ersten und zweiten Motorgenerator MG1 und MG2 verbundene erste und zweite Planetengetriebemechanismus PG1 und PG2 integriert, und erreichen den Zustand, dass sie mit derselben Geschwindigkeit gedreht werden. In diesem Zustand wird die Drehgeschwindigkeit der Antriebsmaschine durch die Rückkopplungssteuerung oder den Betrieb des ersten und zweiten Planetengetriebemechanismus PG1 und PG2 beeinflusst und wird instabil.However, according to the prior art hybrid vehicle control apparatus, when the rotational speed of the output shaft approaches the target rotational speed, the first and second planetary gear mechanisms PG1 and PG2 respectively connected to the first and second motor generators MG1 and MG2 are integrated and reach the state in that they are rotated at the same speed. In this state, the rotation speed of the engine is affected by the feedback control or the operation of the first and second planetary gear mechanisms PG1 and PG2, and becomes unstable.
Zusammenfassung der ErfindungSummary of the invention
Es ist deshalb eine Aufgabe der vorliegenden Erfindung, eine Steuerungsvorrichtung für ein Hybridfahrzeug vorzusehen, das eine stabile Drehgeschwindigkeit einer Antriebsmaschine aufrechterhalten kann, sogar wenn sich eine Differentialdrehgeschwindigkeit eines Planetengetriebemechanismus etwa Null nähert.It is therefore an object of the present invention to provide a control apparatus for a hybrid vehicle that can maintain a stable rotational speed of an engine even when a differential rotational speed of a planetary gear mechanism approaches about zero.
Gemäß einem Aspekt der Ausführungsbeispiele der vorliegenden Erfindung ist eine Steuerungsvorrichtung für ein Hybridfahrzeug vorgesehen, mit: einer Antriebsmaschine, die zum Ausgeben einer Antriebskraft konfiguriert ist; einem Planetengetriebemechanismus, der mit der Antriebsmaschine gekoppelt ist; einem Motorgenerator, der mit dem Planetengetriebemechanismus gekoppelt ist; und einer Ausgangswelle, mit welcher die Antriebsmaschine und der Motorgenerator über den Planetengetriebemechanismus gekoppelt sind, wobei die Steuerungsvorrichtung konfiguriert ist, um einen Ausgabewert der Motorgeneratoren so zu steuern, dass eine Drehgeschwindigkeit der Antriebsmaschine mit einer Soll-Drehgeschwindigkeit der Antriebsmaschine konvergiert, und wobei die Steuerungsvorrichtung eine Steuerungseinrichtung zum Berechnen eines geschätzten Werts der Antriebskraft der Antriebsmaschine, die durch den Planetengetriebemechanismus verloren geht, und zum Berechnen des Ausgabewerts des Motorgenerators im Ansprechen auf den geschätzten Wert umfasst.According to one aspect of the embodiments of the present invention, there is provided a control device for a hybrid vehicle, comprising: a prime mover configured to output a driving force; a planetary gear mechanism coupled to the prime mover; a motor generator coupled to the planetary gear mechanism; and an output shaft to which the prime mover and the motor generator are coupled via the planetary gear mechanism, the control device configured to control an output value of the motor generators so that a rotational speed of the prime mover converges to a target rotational speed of the prime mover, and wherein the control device a controller for calculating an estimated value of Driving force of the prime mover, which is lost by the planetary gear mechanism, and for calculating the output value of the motor generator in response to the estimated value.
Mit dieser Konfiguration wird der Ausgabewert des Motorgenerators gesteuert, während die Antriebskraft der Antriebsmaschine, die durch den Planetengetriebemechanismus verloren geht, geschätzt wird, so dass die Drehgeschwindigkeit der Antriebsmaschine stabil gehalten werden kann, sogar wenn sich die Differentialdrehgeschwindigkeit des Planetengetriebemechanismus etwa Null nähert.With this configuration, the output value of the motor generator is controlled while estimating the driving force of the engine lost by the planetary gear mechanism, so that the rotational speed of the engine can be stably maintained even if the differential rotational speed of the planetary gear mechanism approaches about zero.
