The engine and gearbox receive respectively a signal of load ( alpha ) and a signal of transmission ( OMICRON ). These are established on the base of single signal of power (P) established from the position of the accelerator pedal (p)

Description

PROCEDE DE CONTROLE GLOBAL D'UN GROUPE
MOTO-PROPULSEUR
La présente invention concerne la commande des moteurs thermiques et des boîtes de vitesses de véhicule automobilè.GLOBAL CONTROL METHOD OF A GROUP
MOTO-BOW
The present invention relates to the control of thermal engines and automatic vehicle transmissions.

Elle s'applique à tout véhicule équipé d'un moteur à essence ou Diesel, associé à une boîte de vitesses automatique à rapports discrets ou à variation continue.It applies to any vehicle equipped with a gasoline or diesel engine, associated with a discreet or continuously variable automatic gearbox.

Par la publication US 4893 526, on connaît un système de commande de groupe moto-propulseur à variateur de vitesse, qui détermine un couple (ou une puissance) de consigne à transmettre aux roues du véhicule, à partir de la position de l'accélérateur, et des signaux d'un capteur de rapport ou de régime primaire de transmission.US Pat. No. 4,893,526 discloses a motor-drive unit control system with a variable speed drive, which determines a torque (or a power) that is set to be transmitted to the wheels of the vehicle from the position of the accelerator. , and signals of a ratio sensor or primary transmission regime.

Ce système exploite deux cartographies distinctes, permettant respectivement de déduire de la consigne de couple (ou de puissance) aux roues et de la vitesse du véhicule, un régime primaire ou un rapport de transmission, et une consigne de couple moteur.This system operates two separate maps, respectively allowing to deduce from the setpoint of torque (or power) to the wheels and the speed of the vehicle, a primary speed or a transmission ratio, and a set of engine torque.

Le système de contrôle illustré par la publication US 4893 526, présente l'inconvénient de nécessiter une prise d'information sur l'arbre primaire de la transmission, et de n'être applicable que sur une transmission à rapport continûment variable. The control system illustrated by the publication US 4893 526, has the disadvantage of requiring information taking on the primary shaft of the transmission, and to be applicable only on a continuously variable ratio transmission.

La présente invention vise à s'affranchir du capteur de régime primaire ou de rapport de transmission, et à disposer d'un outil de contrôle global de groupe moto-propulseur, utilisable avec tous les types de transmission automatique ou automatisée, à rapports discrets ou à rapport continûment variable.The present invention aims to overcome the primary speed sensor or transmission ratio, and to have a global control unit powertrain, usable with all types of automatic or automated transmission, discrete reports or continuously variable report.

Elle propose dans ce but que le moteur thermique et le dispositif de changement de vitesses reçoivent au travers de leurs cartographies respectives, une consigne de charge et une consigne de transmission, sur la base d'une même consigne de puissance, établie à partir de la position de la pédale d'accélérateur.It proposes for this purpose that the heat engine and the gearshift device receive through their respective maps, a load setpoint and a transmission setpoint, on the basis of the same power setpoint, established from the position of the accelerator pedal.

Selon un mode de réalisation préférentiel de l'invention, la consigne de puissance est calculée selon une loi définissant la progressivité de la pédale d'accélérateur.According to a preferred embodiment of the invention, the power setpoint is calculated according to a law defining the progressivity of the accelerator pedal.

L'invention prévoit par ailleurs que la consigne de charge du moteur soit déterminée en fonction de la consigne de puissance et de la vitesse de déplacement du véhicule.The invention furthermore provides that the engine load setpoint is determined as a function of the power setpoint and the speed of movement of the vehicle.

D'autres caractéristiques et avantages de l'invention apparaîtront clairement à la lecture de la description suivante d'un mode de réalisation particulier de celle-ci, en se reportant aux dessins annexés, sur lesquels:
- la figure 1 regroupe les différentes unités
fonctionnelles nécessaires à la mise en oeuvre de
l'invention, et
- la figure 2 illustre un mode de réalisation particulier
de celle-ci.Other features and advantages of the invention will become clear from reading the following description of a particular embodiment thereof, with reference to the accompanying drawings, in which:
- Figure 1 groups the different units
functional requirements for the implementation of
the invention, and
FIG. 2 illustrates a particular embodiment
of it.

Sur la figure 1, on a mis en évidence les différentes unités fonctionnelles de calcul nécessaires à la mise en oeuvre de l'invention, regroupées par exemple dans un même calculateur 1, dit calculateur de commande globale du groupe moto-propulseur . In FIG. 1, the various functional units of calculation necessary for the implementation of the invention have been highlighted, grouped for example in the same computer 1, called the overall control computer of the powertrain group.

Le calculateur 1 reçoit de la pédale d'accélérateur 2 une information p relative à la position de celle-ci. L'information p est traité dans une première unité de calcul 3, appliquant une loi de progressivité de la pédale, pour établir une consigne de puissance P à appliquer aux roues pour satisfaire la demande du conducteur. Conformément à l'invention, la consigne P est transmise à une seconde et à une troisième unités de calcul 4, 6, appliquant respectivement des cartographies de moteur et de boîte de vitesses. Au travers de ces cartographies, les unités 4 et 6 traitent la consigne P et l'information de vitesse de déplacement du véhicule v (transmise par la boîte de vitesses 8 dans l'exemple de réalisation non limitatif illustré par la figure 1), pour transmettre au moteur 7 une consigne de charge a et, à la boîte de vitesses 8, une consigne de transmission o, sous la forme d'une consigne de rapport de transmission, ou de régime d'arbre primaire de transmission.The computer 1 receives from the accelerator pedal 2 information p relative to the position thereof. The information p is processed in a first calculation unit 3, applying a law of progressivity of the pedal, to establish a power setpoint P to be applied to the wheels to satisfy the driver's request. According to the invention, the instruction P is transmitted to a second and a third calculation unit 4, 6 respectively applying engine and transmission maps. Through these maps, the units 4 and 6 process the setpoint P and the vehicle traveling speed information v (transmitted by the gearbox 8 in the nonlimiting exemplary embodiment illustrated in FIG. transmit to the engine 7 a load setpoint a and, to the gearbox 8, a transmission setpoint o, in the form of a transmission ratio setpoint, or primary transmission shaft speed.

Grâce à l'introduction de la double consigne a, co dans le groupe moto-propulseur, l'invention vise à commander celuici de façon globale. Le procédé proposé suppose la présence d'un moyen de commande du couple moteur a, indépendant de la position p de la pédale d'accélérateur, ce qui lignifie que la pédale d'accélérateur ne soit pas reliée par câble à l'organe de commande de charge a. Pour un moteur à essence, ceci suppose que le papillon d'admission des gaz soit motorisé, tandis que pour un moteur Diesel, cette commande doit être assurée par une pompe électronique, ou un système d'injection sous pression, par exemple du type Common
Rail. Par ailleurs, ce procédé est applicable avec tout type de boîte automatique, à rapports discrets ou continus.Thanks to the introduction of the dual instruction a, co in the powertrain, the invention aims to control it globally. The proposed method assumes the presence of a motor torque control means a, independent of the position p of the accelerator pedal, which lignifies that the accelerator pedal is not connected by cable to the control member charge a. For a gasoline engine, this assumes that the throttle valve is motorized, while for a diesel engine, this command must be provided by an electronic pump, or a pressure injection system, for example of the Common type.
Rail. Furthermore, this method is applicable with any type of automatic transmission, discrete or continuous reports.

L'invention prévoit en premier lieu de déterminer une consigne de puissance P aux roues à partir de l'information de position de la pédale p, selon une loi définissant la progressivité de la pédale, et d'exploiter celle-ci dans les seconde et troisième unités de calcul 4. Si le mécanisme de changement de vitesses est une transmission automatique munie d'un convertisseur hydrocinétique de couple, l'invention prévoit notamment d'utiliser éventuellement dans l'unité de calcul moteur 4, deux cartographies distinctes, selon que le convertisseur de couple est ponté ou non. Cette disposition, facultative, mais particulièrement avantageuse est illustrée par la figure 2 distinguant dans ce cas, l'exploitation la consigne de puissance P par l'une ou l'autre de ces deux cartographies, ainsi que l'exploitation d'une information sur l'état ponté ou non du convertisseur dans le calcul de la charge a.The invention firstly provides a power instruction P to the wheels from the position information of the pedal p, according to a law defining the progressivity of the pedal, and exploit it in the second and third calculation units 4. If the gearshift mechanism is an automatic transmission provided with a hydrokinetic torque converter, the invention provides in particular for possibly using in the engine calculation unit 4, two separate maps, depending on whether the torque converter is bridged or not. This optional but particularly advantageous arrangement is illustrated by FIG. 2 distinguishing in this case, the exploitation of the power setpoint P by one or other of these two maps, as well as the exploitation of information on the bridged state or not of the converter in the calculation of the load a.

Cette figure illustre une application particulière de l'invention au cas d'un véhicule équipé d'un moteur à essence papillon électrique et d'une transmission à variation continue ou CVT (Continuously Variable Transmission) munie d'un convertisseur hydrocinétique de couple pontable. Elle met en évidence: -l'exploitation du paramètre position de pédale, p selon une loi de progressivité, pour fournir la consigne de puissance P, - l'exploitation de la consigne P, d'une part au travers de l'une ou l'autre des deux cartographies moteur appelées alpha ponté et alpha déponté sur le schéma, selon l'état du convertisseur (information pontage ), et d'autre part au travers de la cartographie du CVT, - l'exploitation du paramètre vitesse de déplacement du véhicule, v au travers de chacune de ces cartographies, et - l'expression des consignes de charge a et de transmission < o sous forme d'une consigne % de pourcentage d'ouverture du papillon motorisé et d'une consigne de régime primaire de la boîte (régime de sortie du convertisseur de couple).This figure illustrates a particular application of the invention in the case of a vehicle equipped with an electric throttle gasoline engine and a continuously variable transmission or CVT (Continuously Variable Transmission) provided with a hydrokinetic torque bridge converter. It highlights: the exploitation of the pedal position parameter, p according to a law of progressivity, to supply the power setpoint P, the exploitation of the setpoint P, firstly through one or the other one of the two engine mappings called alpha bridged and alpha depicted on the diagram, according to the state of the converter (bridging information), and on the other hand through the mapping of the CVT, - the exploitation of the parameter speed of displacement of the vehicle, v through each of these maps, and - the expression of the load instructions a and transmission <o in the form of a setpoint% of the opening percentage of the motorized butterfly and a primary speed setpoint of the box (output speed of the torque converter).

En conclusion, le procédé de commande global d'un groupe moto-propulseur proposé par l'invention présente de nombreux avantages liés à sa simplicité et à ses très larges possibilités d'application. En particulier, il faut souligner qu'à l'inverse des systèmes connus, il n'utilise pas de capteur de rapport ou de régime primaire, et qu'il est applicable aussi bien sur une transmission à variation continue, que sur une transmission à rapports discrets. In conclusion, the overall control method of a powertrain group proposed by the invention has many advantages related to its simplicity and its very wide application possibilities. In particular, it should be emphasized that, unlike the known systems, it does not use a ratio or primary speed sensor, and that it is applicable both to a continuously variable transmission, discreet reports.
