Abstract

The system monitors the torque demanded in order to determine the optimum source of this power from electric and thermal engines. The system includes a parallel hybrid drive for a motor vehicle, comprising an electric motor (1) and a thermal engine (2) both linked in rotation to a mechanical drive train (3). This allows the motors to provide power selectively to the vehicle wheels (4). The control includes a number of blocks for managing the demand for torque, controlled by a block determining the operating conditions of the vehicle (8), and a block (10) determining the couple received and receiving information from other monitoring blocks (6,7,12). A further system determines the status of the alternator-starter (9), in order to control the couple provided by both the electric motor and the thermal motor, optimizing the performance compromise between performance and efficiency.

Description

La présente invention concerne un système de commande couple d'une motorisation hybride parallèle pour véhicule automobile. The present invention relates to a torque control system for a parallel hybrid motorization for a motor vehicle.

Elle rapporte, plus particulièrement, à un système commande en couple des moteurs thermique et électrique constituant motorisation hybride parallèle et en particulier d'un alterno-démarreur. It relates, more particularly, to a torque control system of the thermal and electric motors constituting a parallel hybrid motorization and in particular of an alternator-starter.

Quelques définitions sont rappelées ci-après. Les hybrides parallèles sont des groupes motopropulseurs dans lesquels un moteur thermique une machine électrique alimentée une batterie d'accumulateurs et une transmission mécanique sont couplés par l'intermédiaire un dispositif permettant de les lier en rotation les uns aux autres. La machine électrique étant susceptible de fonctionner indifféremment en moteur ou en générateur de courant. Ce type motorisation présente l'avantage de pouvoir utiliser les deux types de propulsion thermique et électrique alternativement ou simultanément Le passage d'une configuration de fonctionnement à une autre est assuré par des moyens de commande qui assurent toutes les fonctions commande de gestion de puissance. L'alterno-démarreur est un hybride parallele particulier, qui comprend un moteur électrique géré électroniquement, intercalé entre le moteur et la boîte de vitesses remplaçant le démarreur l'alternateur et le volant moteur traditionnel. Ce type d'hybride comporte en outre deux batteries une batterie de servitude dédiée à l'alimentation du réseau de bord notamment en phase de roulage et une batterie de puissance dédiée principalement à fourniture d'énergie pour la machine électrique I1 s'avère que dans tel type de groupe motopropulseur, de nombreux paramètres peuvent influencer sur la demande couple des moteurs électrique et thermique. Ces différents paramètres sont évolutifs avec les avances technologiques ou les contraintes réglementaires de sorte qu'il est nécessaire de revoir complètement le système commande en couple lorsque celles-ci arrivent L'invention a pour de remédier à cet inconvénient en proposant avantageusement un système de commande en couple généralisé qui présente une architecture à la fois modulaire et évolutive. Some definitions are recalled below. Parallel hybrids are powertrains in which a heat engine, an electric machine powered by an accumulator battery and a mechanical transmission are coupled via a device making it possible to link them in rotation with each other. The electric machine being capable of operating either as a motor or as a current generator. This type of motorization has the advantage of being able to use the two types of thermal and electric propulsion alternately or simultaneously. The transition from one operating configuration to another is ensured by control means which perform all of the power management control functions. The alternator-starter is a particular parallel hybrid, which includes an electric motor managed electronically, interposed between the engine and the gearbox replacing the starter, the alternator and the traditional flywheel. This type of hybrid also includes two batteries, a service battery dedicated to supplying the on-board network, especially during taxiing, and a power battery dedicated mainly to supplying energy for the electric machine I1. As with this type of powertrain, many parameters can influence the torque demand of electric and thermal engines.

All this information, torque instructions, in generation or in engine, from the allocation or torque request management blocks 6, and 12 for an identified organ or function defined above and states or alerts these same functions are transmitted to the torque determination block 10. On the other hand, the life situation determination block of the alternator-starter system 9 transmits to the torque determination block 10, the information concerning its life situation enabling it to draw up the final setpoint of torque distributed between the engine on the one hand and the electric machine on the other hand, allocating, depending on the case of life, priority to the functions of powertrain management 6, to 'electric autonomy 7, or to dynamic services 12.

Advantageously, a cooling block 13 ensures the start-up of a fan as a function of the temperature criteria of the heat engine and of the service and power batteries.

On conçoit alors qu'un système soit évolutif car une fonction de demande de couple (de traction ou de génération) peut facilement être ajoutée. De même, n'importe quel bloc peut être modifié indépendamment autres en cas de changement de la machine électrique, du moteur thermique et éventuellement des conditions véhicule d'arrêt ou de demande de démarrage. It is therefore conceivable that a system is scalable because a torque demand function (traction or generation) can easily be added. Likewise, any block can be modified independently of others in the event of a change of the electric machine, the heat engine and possibly the conditions of the vehicle stopped or of the request to start.

De plus, l'organisation système décrit ci- dessus permet de s'adapter quel que soit le nombre de batteries de puissance. In addition, the system organization described above allows adapting regardless of the number of power batteries.

I1 va de soi bien entendu que différents modes de réalisation d'un système peuvent être envisagés.It goes without saying of course that different embodiments of a system can be envisaged.
