Description

Procédé de gestion d'un événement atypique lors du fonctionnement d'un véhicule automobile Method of managing an atypical event during operation of a motor vehicle
La présente invention concerne un procédé de gestion d'un événement atypique lors du fonctionnement d'un véhicule automobile comportant un moteur thermique auquel est associé un circuit de refroidissement comprenant une vanne de répartition électrique reliée à une unité de commande. The present invention relates to a method of managing an atypical event during the operation of a motor vehicle comprising a heat engine which is associated with a cooling circuit comprising an electric distribution valve connected to a control unit.
ARRIÈRE-PLAN DE L'INVENTION BACKGROUND OF THE INVENTION
Dans les véhicules automobile comportant un moteur thermique auquel est associé un circuit de refroidissement il est connu d'implanter une vanne de répartition électrique reliée à une unité de commande pour assurer une distribution du liquide de refroidissement vers les différents équipements associés au moteur thermique afin d'optimiser le fonctionnement du moteur thermique et de minimiser la pollution engendrée par le moteur thermique.  In motor vehicles comprising a heat engine with which a cooling circuit is associated, it is known to install an electric distribution valve connected to a control unit to ensure a distribution of the coolant to the various equipment associated with the engine in order to optimize the operation of the engine and minimize the pollution generated by the engine.
OBJET DE L'INVENTION OBJECT OF THE INVENTION
L'invention concerne une nouvelle application de la vanne de répartition électrique visant à assurer la gestion d'événements atypiques, a priori non concernés par le fonctionnement du moteur, lors du fonctionnement du véhicule automobile.  The invention relates to a new application of the electrical distribution valve to ensure the management of atypical events, a priori not affected by the operation of the engine, during operation of the motor vehicle.
BRÈVE DESCRIPTION DE L'INVENTION BRIEF DESCRIPTION OF THE INVENTION
En vue de la réalisation de ce but, on propose selon l'invention un procédé de gestion d'un événement atypique lors du fonctionnement d'un véhicule automobile comportant un moteur thermique auquel est associé un circuit de refroidissement comprenant une vanne de répartition électrique reliée à une unité de commande, caractérisé en ce qu'il comporte les étapes successives suivantes : With a view to achieving this object, the invention proposes a method for managing an atypical event during the operation of a motor vehicle comprising a heat engine which is associated with a cooling circuit comprising a connected electrical distribution valve. to a control unit, characterized in that it comprises the following successive steps:
- rechercher une relation de corrélation entre l'événement atypique et une température du moteur thermique,  search for a correlation relation between the atypical event and a temperature of the heat engine,
- configurer l'unité de commande en fonction de la relation de corrélation pour élaborer un signal de commande lors de la survenance de l'événement atypique, et configuring the control unit according to the correlation relation to formulate a control signal at the occurrence of the atypical event, and
- appliquer le signal de commande à la vanne de répartition. - apply the control signal to the distribution valve.
Selon un premier mode de mise en œuvre du procédé selon l'invention, l'événement atypique est une circonstance dans laquelle un danger est lié à une température élevée du moteur thermique . Plus  According to a first mode of implementation of the method according to the invention, the atypical event is a circumstance in which a danger is linked to a high temperature of the engine. More
particulièrement l'événement atypique est un passage dans un tunnel, et le signal de commande est élaboré pour commander un abaissement de la température du moteur. particularly the atypical event is a passage in a tunnel, and the control signal is developed to control a lowering of the engine temperature.
Il a en effet été constaté qu'en raison du confinement de l'air dans un tunnel la température du moteur thermique d'un véhicule automobile a tendance à s'élever de sorte que le risque d'incendie est plus important que sur une route dégagée, en particulier pour les poids-lourds. En abaissant préventivement la température du moteur on minimise donc le risque de déclenchement d'un incendie.  It has indeed been found that because of the confinement of air in a tunnel the temperature of the engine of a motor vehicle tends to rise so that the risk of fire is greater than on a road unobstructed, especially for heavy goods vehicles. Preventing the temperature of the engine thus minimizes the risk of a fire.
Selon un deuxième mode de mise en œuvre de l'invention en relation avec un véhicule équipé d'un système de freinage hydraulique, l'événement atypique est une panne du système de freinage, et le signal de commande est élaboré pour commander un abaissement de la température du moteur. En effet, un abaissement de la température du moteur provoque une augmentation de la viscosité de l'huile de lubrification du moteur ce qui permet d'augmenter le frein moteur et donc de compenser partiellement la perte de freinage due à la panne du circuit de freinage. De préférence dans ce cas, le signal de commande est élaboré automatiquement lors d'une détection d'une défaillance, telle qu'une pression anormalement basse par exemple, dans le système de freinage . According to a second embodiment of the invention in connection with a vehicle equipped with a hydraulic braking system, the atypical event is a failure of the braking system, and the control signal is developed to control a lowering of the braking system. the engine temperature. Indeed, a lowering of the engine temperature causes an increase in the viscosity of the lubricating oil of the engine which increases the engine brake and therefore compensate partially the loss of braking due to the failure of the brake system. Preferably in this case, the control signal is developed automatically upon detection of a failure, such as an abnormally low pressure for example, in the braking system.
Selon un troisième mode de mise en œuvre de l'invention, l'événement atypique est une température anormalement basse dans l'habitacle du véhicule et le signal de commande est élaboré pour commander un transfert accru de fluide de chauffage vers l'échangeur de chaleur de l'habitacle. Le signal de commande peut également être élaboré pour commander une augmentation de la température du moteur.  According to a third mode of implementation of the invention, the atypical event is an abnormally low temperature in the passenger compartment of the vehicle and the control signal is developed to control an increased transfer of heating fluid to the heat exchanger of the cockpit. The control signal can also be developed to control an increase in the engine temperature.
Selon un quatrième mode de mise en œuvre du procédé selon l'invention, l'événement atypique est une intervention sur le véhicule et le signal de commande est élaboré pour commander un abaissement de la température du moteur. Le signal de commande peut par exemple également être élaboré pour commander un fonctionnement des ventilateurs moteur en parallèle. Ce mode de mise en œuvre du procédé selon l'invention permet ainsi de réduire le temps d'attente avant d'intervenir sur un véhicule, ce qui facilite l'organisation des tâches dans un garage .  According to a fourth mode of implementation of the method according to the invention, the atypical event is an intervention on the vehicle and the control signal is developed to control a lowering of the engine temperature. The control signal can for example also be developed to control operation of the motor fans in parallel. This mode of implementation of the method according to the invention thus reduces the waiting time before working on a vehicle, which facilitates the organization of tasks in a garage.
Selon un cinquième mode de mise en œuvre du procédé selon l'invention, l'événement atypique est une descente et le signal de commande est élaboré pour commander un abaissement de la température du moteur. Comme dans le cas d'une panne de freinage, l'abaissement de la température du moteur entraîne une augmentation de la viscosité de l'huile de lubrification de sorte que l'effet de frein moteur est accru.  According to a fifth mode of implementation of the method according to the invention, the atypical event is a descent and the control signal is developed to control a lowering of the engine temperature. As in the case of a brake failure, lowering the engine temperature results in an increase in the viscosity of the lubricating oil so that the effect of the engine brake is increased.
De préférence dans ce cas, le signal de commande est élaboré automatiquement lors d'une détection d'une configuration de descente présentant une pente supérieure à un seuil prédéfini. Preferably in this case, the control signal is automatically generated during a detection of a descent configuration having a slope greater than a predefined threshold.
Selon encore un autre mode de mise en œuvre du procédé selon l'invention en relation avec un véhicule équipé d'un système de freinage comprenant un disque ventilé par le circuit de refroidissement, l'événement atypique est une température du disque supérieure à un seuil prédéfini et le signal de commande est élaboré pour commander un abaissement de la température du moteur. Ce mode de réalisation peut par exemple être mis en œuvre par un système de freinage de type électromagnétique qui rejette de l'énergie dans le circuit de refroidissement.  According to yet another embodiment of the method according to the invention in connection with a vehicle equipped with a braking system comprising a disk ventilated by the cooling circuit, the atypical event is a disk temperature above a threshold predefined and the control signal is developed to control a lowering of the engine temperature. This embodiment can for example be implemented by an electromagnetic type braking system which rejects energy in the cooling circuit.
D'autres caractéristiques et avantages de l'invention apparaîtront encore à la lecture de la description qui suit d'un mode de réalisation préféré non limitatif de l'invention en référence à la figure 1 qui est une représentation schématique des parties d'un véhicule automobile concernées par l'invention.  Other features and advantages of the invention will become apparent on reading the following description of a preferred non-limiting embodiment of the invention with reference to FIG. 1 which is a schematic representation of the parts of a vehicle involved in the invention.
DESCRIPTION DETAILLEE DE L ' INVENTION DETAILED DESCRIPTION OF THE INVENTION
En référence à la figure, le véhicule automobile comporte de façon connue en soi un moteur thermique 1 auquel est associé un circuit de refroidissement comprenant un réseau de tuyauteries contenant un liquide de refroidissement et reliant entre eux les différents organes du circuit de refroidissement, notamment un radiateur 2 du compartiment moteur, un radiateur 3 de l'habitacle, et une vanne de répartition électrique 4. De façon également connue en soi, la vanne de répartition 4 est reliée à une unité de commande 5 qui assure une gestion du fonctionnement du moteur en fonction d'un certain nombre de paramètres, notamment la température du moteur donnée par un capteur 6.  With reference to the figure, the motor vehicle comprises, in a manner known per se, a heat engine 1 which is associated with a cooling circuit comprising a network of pipes containing a cooling liquid and interconnecting the various members of the cooling circuit, in particular a radiator 2 of the engine compartment, a radiator 3 of the passenger compartment, and an electric distribution valve 4. In a manner also known per se, the distribution valve 4 is connected to a control unit 5 which provides management of the engine operation according to a certain number of parameters, in particular the engine temperature given by a sensor 6.
Également de façon connue en soi, et comme illustré sur cette figure 1, le véhicule peut comporter un circuit de freinage comprenant une pédale 7 reliées par un conduit de freinage 8 à un étrier de frein 9 monté en regard d'un disque 10. Also in a manner known per se, and as illustrated in FIG. 1, the vehicle may comprise a braking circuit comprising a pedal 7 connected by a braking line 8 to a brake caliper 9 mounted facing a disk 10.
Selon l'invention, l'unité de commande 5 est configurée pour gérer différents événements atypiques pour lesquels il existe une relation de corrélation entre les événements atypiques et la température du moteur thermique .  According to the invention, the control unit 5 is configured to handle different atypical events for which there is a correlation relationship between the atypical events and the temperature of the engine.
Selon un premier aspect particulier de l'invention, le véhicule est équipé d'un interrupteur 11 relié à l'unité de commande 5 pour déclencher la gestion d'une circonstance dans laquelle un danger est lié à une température élevée du moteur thermique, typiquement le passage dans un tunnel.  According to a first particular aspect of the invention, the vehicle is equipped with a switch 11 connected to the control unit 5 to trigger the management of a circumstance in which a danger is linked to a high temperature of the heat engine, typically the passage in a tunnel.
L'interrupteur 11 peut également être utilisé pour déclencher un abaissement de la température du moteur afin de permettre une intervention rapide lorsque le véhicule est amené dans un garage. En effet, au ralenti, la capacité de refroidissement du radiateur est très supérieure à l'énergie dépensée par le moteur, de sorte que par un réglage approprié de la vanne de répartition et la mise en route du ventilateur associé au radiateur du compartiment moteur, il est possible de réduire la température du moteur de façon significative, par exemple de plusieurs dizaines de degrés.  The switch 11 can also be used to trigger a lowering of the engine temperature to allow a quick response when the vehicle is brought into a garage. Indeed, at idle, the cooling capacity of the radiator is much higher than the energy expended by the engine, so that by appropriate adjustment of the distribution valve and the startup of the fan associated with the radiator of the engine compartment, it is possible to reduce the engine temperature significantly, for example by several tens of degrees.
Selon un deuxième aspect de l'invention, la pédale de frein 7 est portée par un boîtier 12 contenant un détecteur de pression relié à l'unité de commande 5 pour déclencher un abaissement de la température du moteur lorsque la pression dans le circuit de freinage est anormalement basse.  According to a second aspect of the invention, the brake pedal 7 is carried by a housing 12 containing a pressure sensor connected to the control unit 5 to trigger a lowering of the engine temperature when the pressure in the braking circuit is abnormally low.
Selon un troisième aspect de l'invention, un détecteur de température 13 de l'habitacle est relié à l'unité de commande 5 pour déclencher une commande d'un transfert accru de flux de chauffage vers l'échangeur de chaleur de l'habitat. According to a third aspect of the invention, a cabin temperature detector 13 is connected to the control unit 5 to trigger control of an increased transfer of heating flow to the heat exchanger. heat of the habitat.
Selon un autre aspect de l'invention, le véhicule est équipé d'un détecteur d'inclinaison 14 relié à l'unité de commande 5 pour déclencher un abaissement de la température du moteur lorsque l'inclinaison du véhicule correspond à une configuration de descente présentant une pente supérieure à un seuil prédéfini. On augmente ainsi le frein moteur pendant une forte descente. Il est à noté que ce détecteur d'inclinaison peut comprendre un boîtier GPS, ou des moyens de positionnement et de localisation de sorte à détecter une pente sur laquelle circule le véhicule.  According to another aspect of the invention, the vehicle is equipped with an inclination sensor 14 connected to the control unit 5 to trigger a lowering of the engine temperature when the inclination of the vehicle corresponds to a descent configuration with a slope greater than a predefined threshold. This increases the engine brake during a strong descent. It should be noted that this inclination detector may comprise a GPS box, or positioning and locating means so as to detect a slope on which the vehicle is traveling.
Selon encore un aspect de l'invention, en relation avec un véhicule dont les disques de frein 10 sont ventilés de façon connue en soi par une buse 15, l'étrier 9 est équipé d'un capteur de température relié à l'unité de commande 5 pour déclencher un abaissement de la température du moteur lorsque la température du disque est supérieure à un seuil prédéfini.  According to another aspect of the invention, in connection with a vehicle whose brake disks 10 are ventilated in a manner known per se by a nozzle 15, the stirrup 9 is equipped with a temperature sensor connected to the unit of command 5 to trigger a lowering of the engine temperature when the disk temperature is above a predefined threshold.
Bien entendu l'invention n'est pas limitée aux modes de mise en œuvre décrits et on peut y apporter des variantes de mise en œuvre sans sortir du cadre de l'invention telle que définie par les revendications.  Naturally, the invention is not limited to the embodiments described and variations can be made to implement without departing from the scope of the invention as defined by the claims.
En particulier, bien que dans le cas d'un passage dans un tunnel il ait été prévu d'actionner un interrupteur pour déclencher l'abaissement de température du moteur, ce déclenchement pourrait par exemple être rendu automatique par des bornes convenablement placées sur le réseau routier associées à un détecteur porté par les véhicules configurés conformément à l'invention, par des moyens de positionnement et de localisation, ou bien par des détecteurs de luminosité.  In particular, although in the case of passage through a tunnel it has been planned to actuate a switch to trigger the lowering of the engine temperature, this trigger could for example be made automatic by terminals properly placed on the network. associated with a detector carried by the vehicles configured in accordance with the invention, by positioning and locating means, or by luminosity detectors.
