Description

DESCRIPTION DESCRIPTION
TITRE : Système de gestion de la qualité de l’air dans un habitacle de véhicule sur un trajet prédéterminé TITLE: Air quality management system in a vehicle cabin on a predetermined route
La présente invention concerne les véhicules automobiles et plus particulièrement les systèmes de gestion de la qualité de l’ air dans un habitacle de véhicule. The present invention relates to motor vehicles and more particularly to systems for managing the quality of the air in a vehicle cabin.
Aujourd’hui, la qualité de l’ air extérieur représente un enjeu majeur pour la santé publique et l’environnement. En effet, il est établi que les niveaux de pollution actuels de l’ air ambiant ont un impact sur la santé humaine, notamment au niveau respiratoire et cardiovasculaire. Today, the quality of outdoor air is a major issue for public health and the environment. Indeed, it is established that the current levels of pollution of the ambient air have an impact on human health, in particular at the respiratory and cardiovascular level.
Les sources émettrices de polluants sont multiples et peuvent être d’origine anthropique ou naturelle. On peut citer par exemple la production liée aux combustions, ce qui permet d’ enregistrer des niveaux record de pollution dans les métropoles à forte densité de véhicules, et particulièrement au niveau des voies de circulation. The sources of pollutants are multiple and can be of anthropogenic or natural origin. One can cite, for example, the production linked to combustion, which makes it possible to record record levels of pollution in metropolitan areas with a high density of vehicles, and particularly at the level of traffic lanes.
Cependant, la concentration de polluants dans l’habitacle d’ un véhicule peut être 3 à 5 fois plus importante qu’ à l’ extérieur. However, the concentration of pollutants in the interior of a vehicle can be 3 to 5 times greater than outside.
Par ailleurs, la circulation de ces mêmes véhicules remet aussi en suspension dans l’ air des particules qui sont, à leur tour, aspirées dans le véhicule. Par conséquent, les passagers inhalent des polluants composés de particules de carbone, d’oxyde d’ azote, de monoxyde de carbone...etc. In addition, the movement of these same vehicles also resuspends particles in the air which are, in turn, sucked into the vehicle. As a result, passengers inhale pollutants composed of carbon particles, nitrogen oxide, carbon monoxide, etc.
Quant à la pollution intérieure des véhicules, elle peut aussi comprendre des composants organiques volatiles libérés notamment par les colles, peintures, matières plastiques et moisissures. Aujourd’hui, les véhicules sont souvent équipés d’ un système de ventilation pouvant être configuré en mode recyclage d’ air. Les passagers d’un véhicule sont non seulement exposés à la pollution de l’ air venant de l’extérieur du véhicule, mais aussi éventuellement aux polluants issus des émissions des matériaux de l’habitacle et au CO2 dont la concentration peut augmenter rapidement au sein de l’habitacle, selon les conditions de ventilation et de chauffage. As for the interior pollution of vehicles, it can also include volatile organic components released in particular by glues, paints, plastics and mold. Today, vehicles are often fitted with a ventilation system that can be configured for recirculation mode. Passengers in a vehicle are not only exposed to air pollution coming from outside the vehicle, but also possibly to pollutants from emissions from passenger compartment materials and to CO2, the concentration of which is can increase rapidly within the passenger compartment, depending on ventilation and heating conditions.
Le nombre de passagers dans 1’habitacle est également un facteur à prendre en compte et peut contribuer à l’ augmentation du taux du C02. De plus, selon certaines conditions de ventilation et de chauffage, notamment en condition de recyclage, le niveau d’humidité tend également à augmenter et ainsi embuer les vitres de l’habitacle, ce qui rend la conduite dangereuse. The number of passengers in the cabin is also a factor to be taken into account and may contribute to the increase in the level of C02. In addition, depending on certain ventilation and heating conditions, especially in recycling conditions, the humidity level also tends to increase and thus fog the windows of the passenger compartment, which makes driving dangerous.
Ainsi, dans ces conditions, le mode recyclage ne peut pas être maintenu. Il faut ouvrir les volets d’entrée d’ air même si la pollution extérieure est plus importante ou est amenée à l’être sur le trajet à parcourir. Cela conduit à un encrassement prématuré des filtres à particules et à une surconsommation du système de conditionnement d’ air qui doit compenser l’ écart de température entre l’ air frais aspiré et l’ air de l’habitacle. Thus, under these conditions, the recycling mode cannot be maintained. The air intake flaps must be opened even if the exterior pollution is greater or is likely to be on the route to be traveled. This leads to premature clogging of the particulate filters and to overconsumption of the air conditioning system, which must compensate for the temperature difference between the fresh air drawn in and the air in the passenger compartment.
Il existe donc un besoin d’ utiliser un système automatisé apte à limiter les risques d’ exposition des passagers à la pollution et à l’humidité en fonction de l’ environnement dans lequel évolue le véhicule sans accroître sa consommation et tout en maintenant le confort thermique de l’habitacle optimal. There is therefore a need to use an automated system capable of limiting the risks of passenger exposure to pollution and humidity depending on the environment in which the vehicle operates without increasing its consumption and while maintaining comfort. optimum interior thermal performance.
Au vu de ce qui précède, l’invention se proposer de pallier les contraintes précitées en proposant un nouveau dispositif de gestion de la qualité de l’ air dans l’habitacle du véhicule en fonction d’un trajet prédéterminé. L’invention a donc pour objet, selon un premier aspect, un procédé de gestion de la qualité de l’ air dans un habitacle de véhicule sur un trajet prédéterminé, comprenant une acquisition de données relatives à la pollution de l’ air autour et à l’intérieur du véhicule sur ledit trajet, et une détermination du niveau de pollution de l’ air autour et à l’ intérieur du véhicule à partir desdites données. In view of the foregoing, the invention proposes to alleviate the aforementioned constraints by proposing a new device for managing the quality of the air in the passenger compartment of the vehicle according to a predetermined route. The subject of the invention is therefore, according to a first aspect, a method for managing the quality of the air in a vehicle interior over a predetermined route, comprising an acquisition of data relating to the pollution of the air around and to inside the vehicle on said route, and determining the level of air pollution around and inside the vehicle from said data.
Le procédé comprend une mise en œuvre du recyclage de l’ air présent dans l’habitacle en fonction de l’ évolution du niveau de pollution de l’ air présent autour et à l’intérieur du véhicule. Par « trajet prédéterminé » on entend un trajet que le véhicule est amené à parcourir. Bien évidemment, le trajet peut être mis à jour au cours de celui-ci. The method comprises implementing the recycling of the air present in the passenger compartment as a function of the change in the level of pollution of the air present around and inside the vehicle. By “predetermined path” is meant a path that the vehicle is required to travel. Obviously, the trip can be updated during it.
La prédétermination du trajet permet de définir les niveaux de pollution de l’ environnement dans lequel le véhicule circulera, et de pouvoir anticiper la gestion de la qualité de l’ air de l’habitacle. The predetermination of the route makes it possible to define the pollution levels of the environment in which the vehicle will be traveling, and to be able to anticipate the management of the quality of the air in the passenger compartment.
Ainsi, les données relatives au trajet permettent d’ acquérir les données relatives à la pollution à l’ instant présent et au niveau des différents points de passage afin de prendre une décision sur la mise en œuvre ou l’ arrêt du recyclage de l’ air présent dans l’habitacle. Thus, the data relating to the journey makes it possible to acquire the data relating to the pollution at the present moment and at the level of the various points of passage in order to take a decision on the implementation or the stop of the air recycling. present in the passenger compartment.
Autrement dit, on détermine sur un trajet donné à quel moment il sera nécessaire de fermer les volets d’entrée d’ air ou de les ouvrir. In other words, we determine on a given route when it will be necessary to close or open the air inlet flaps.
Avantageusement, la mise en œuvre du recyclage comprend une activation d’un premier filtrage de l’ air extérieur apte à pénétrer dans l’habitacle et d’ un deuxième filtrage de l’ air présent dans l’habitacle. Advantageously, the implementation of the recycling comprises an activation of a first filtering of the outside air able to enter the passenger compartment and of a second filtering of the air present in the passenger compartment.
L’ air entrant dans l’habitacle passe par un premier filtrage, assuré par un premier filtre à air disposé dans le système de climatisation, mais aussi par un deuxième filtre à air haute performance agencé en entrée d’ air. Ce dernier est donc placé en amont du système de climatisation du véhicule. Ce filtre à air peut par exemple n’être activé qu’en cas de détection de particules fines à l’ extérieur du véhicule. The air entering the passenger compartment passes through a first filtering, provided by a first air filter placed in the air conditioning system, but also by a second high performance air filter arranged at the air inlet. The latter is therefore placed upstream of the vehicle's air conditioning system. This air filter can for example only be activated if fine particles are detected outside the vehicle.
Quant au deuxième filtrage est réalisé via un filtre à air classique. As for the second filtering is carried out via a conventional air filter.
De préférence, le premier filtrage comprend un traitement des polluants particulaires, gazeux et des particules fines contenues dans l’ air extérieur. Preferably, the first filtering comprises a treatment of particulate pollutants, gaseous and fine particles contained in the outside air.
Il est à noter que lorsque le deuxième filtre à air haute performance est soumis à la présence des particules fines, il est avantageux de le protéger par un troisième filtre à air, placé en amont du filtre hautement efficace, afin d’ allonger sa durée de vie. It should be noted that when the second high performance air filter is subjected to the presence of fine particles, it is advantageous to protect it by a third air filter, placed upstream of the highly efficient filter, in order to extend its service life. life.
On peut citer comme polluant particulaire le pollen et comme polluant gazeux, le benzène. Mention may be made, as particulate pollutant, of pollen and as gaseous pollutant, of benzene.
Quant aux particules ultrafines, on entend toute particule de taille nanométrique (diamètre inférieur à 100 nm). Préférentiellement, le deuxième filtrage est en outre réalisé au moyen d’ un filtre à air et comprend en outre un traitement des polluants gazeux de l’habitacle apte à être activé si la concentration des polluants gazeux de l’ air présent dans l’habitacle est supérieure à un seuil prédéterminé. As for ultrafine particles, we mean any particle of nanometric size (diameter less than 100 nm). Preferably, the second filtering is also carried out by means of an air filter and further comprises a treatment of the gaseous pollutants of the passenger compartment capable of being activated if the concentration of the gaseous pollutants of the air present in the passenger compartment is. greater than a predetermined threshold.
Le filtre à air, qui peut être optionnel, est constitué notamment de charbon actif, de MOF (pour « Metal-Organic framework » en anglais) et/ou d’ autres absorbants et est de préférence activé qu’en cas de mise en œuvre du recyclage et s’ il y a une détection d’un niveau de concentration de polluants gazeux élevé et dangereux pour la santé des passagers, correspondant par exemple à un indice de qualité de l’ air entre 151 et 200, tel que défini par l’ Agence européenne pour l’ Environnement. The air filter, which can be optional, consists in particular of activated carbon, MOF (for "Metal-Organic framework" in English) and / or other absorbents and is preferably activated only in the event of use. recycling and if there is a detection of a high level of gaseous pollutant concentration dangerous for the health of passengers, corresponding for example to an air quality index between 151 and 200, as defined by European Environment Agency.
Bien sûr, le seuil prédéterminé n’est pas limité à cet indice mais peut être issu d’ autres organismes ou élaboré en interne par le constructeur automobile. Of course, the predetermined threshold is not limited to this index but can come from other organizations or developed in-house by the car manufacturer.
De préférence, l’ acquisition de données relatives à la pollution autour du véhicule comprend au moins une mesure d’ une grandeur physique par au moins un capteur de mesure externe disposé sur le véhicule. Ledit au moins un capteur peut être installé en entrée d’ air ou à l’extérieur sur toute partie du véhicule permettant un bon maintien dudit au moins un capteur en position et l’ obtention de valeurs précises et non aléatoires. Preferably, the acquisition of data relating to the pollution around the vehicle comprises at least one measurement of a physical quantity by at least one external measurement sensor arranged on the vehicle. Said at least one sensor can be installed at the air inlet or outside on any part of the vehicle allowing said at least one sensor to be properly maintained in position and obtaining precise and non-random values.
L’homme du métier saura choisir la grandeur physique à mesurer ainsi que le capteur externe adapté au véhicule. Those skilled in the art will know how to choose the physical quantity to be measured as well as the external sensor suitable for the vehicle.
Avantageusement, l’ acquisition de données relatives à la pollution présente dans l’habitacle comprend au moins une mesure d’ une grandeur physique par au moins un capteur de mesure interne disposé dans l’habitacle. Afin de connaître le niveau de pollution à l’ intérieur de l’habitacle, ce dernier comprend au moins un capteur apte à mesurer le niveau de polluants gazeux qui s’ y trouve. On peut citer par exemple un capteur issu de la technologie optique ou électrochimique. L’homme du métier saura choisir la grandeur physique à mesurer ainsi que le capteur interne adapté au véhicule. Advantageously, the acquisition of data relating to the pollution present in the passenger compartment comprises at least one measurement of a physical quantity by at least one internal measurement sensor placed in the passenger compartment. In order to know the level of pollution inside the passenger compartment, the latter comprises at least one sensor capable of measuring the level of gaseous pollutants therein.

L’invention a encore pour objet un véhicule comprenant un système de gestion de la qualité de l’ air dans un habitacle sur un trajet prédéterminé tel que défini ci-dessus. A further subject of the invention is a vehicle comprising a system for managing the quality of the air in a passenger compartment over a predetermined route as defined above.
D’ autres buts, caractéristiques et avantages de l’ invention apparaîtront à la lecture de la description suivante, donnée uniquement à titre d’exemple non limitatif, et faite en référence aux dessins annexés sur lesquels : [Fig 1 ] illustre de façon schématique un système de gestion de la qualité de l’ air dans l’habitacle d’un véhicule selon un mode de réalisation de l’invention. Other objects, characteristics and advantages of the invention will become apparent on reading the following description, given solely by way of non-limiting example, and made with reference to the appended drawings in which: [FIG. 1] illustrates schematically a system for managing the quality of the air in the passenger compartment of a vehicle according to one embodiment of the invention.
[Fig 2] illustre une phase de mise en recyclage sur un trajet donné. Sur la figure 1 est représentée un véhicule automobile 1 comprenant un système de gestion de la qualité de l’ air 2 dans l’habitacle dudit véhicule 1. Le système de gestion 2 est apte à mettre en œuvre ou à arrêter le système de recyclage de l’ air du système de climatisation du véhicule 1 de structure classique et connue. [Fig 2] illustrates a recycling phase on a given route. In FIG. 1 is shown a motor vehicle 1 comprising an air quality management system 2 in the passenger compartment of said vehicle 1. The management system 2 is capable of implementing or stopping the air recycling system of the air conditioning system of the vehicle 1 of conventional and known structure.
Il permet donc de protéger les passagers de la pollution de l’ air sur le trajet prédéterminé. It therefore helps protect passengers from air pollution on the predetermined route.
Pour ce faire, le système de gestion de la qualité de l’ air 2 est couplé audit système de recyclage et plus particulièrement à une entrée d’ air apte à contrôler l’ air extérieur entrant dans le véhicule 1. To do this, the air quality management system 2 is coupled to said recycling system and more particularly to an air inlet capable of controlling the outside air entering the vehicle 1.
Plus particulièrement, le contrôle de l’ air extérieur se fait par le biais d’ un volet mobile de commande de recyclage 7, apte à se déplacer d’une première position correspondant à une fermeture totale du volet mobile 7 à une deuxième position correspondant à une ouverture totale ou partielle du volet 7. More particularly, the control of the outside air is effected by means of a movable recycling control flap 7, able to move from a first position corresponding to a total closure of the movable flap 7 to a second position corresponding to total or partial opening of the shutter 7.
L’ouverture partielle correspond à une position intermédiaire située entre la première position et la deuxième position. Partial opening corresponds to an intermediate position located between the first position and the second position.
De cette manière, ledit volet 7 peut réguler le débit d’ air extérieur entrant dans le véhicule 1. In this way, said flap 7 can regulate the flow of outside air entering the vehicle 1.
Cependant, l’ air extérieur destiné à pénétrer dans l’habitacle du véhicule 1 peut être chargé en polluants qu’on filtre au moyen d’un premier système de filtrage 8 combiné dans le système de climatisation. However, the outside air intended to enter the cabin of the vehicle 1 may be loaded with pollutants which are filtered by means of a first filtering system 8 combined in the air conditioning system.
Le premier système de filtrage 8 comprend ici un premier filtre 81 apte à filtrer les polluants particulaires et gazeux mais aussi un deuxième filtre à air 82 haute performance, disposé en entrée d’ air et en amont du système de climatisation et apte à filtrer les particules les plus fines contenues dans l’ air extérieur. The first filtering system 8 here comprises a first filter 81 capable of filtering particulate and gaseous pollutants but also a second high performance air filter 82, arranged at the air inlet and upstream of the air conditioning system and capable of filtering particles. the finest contained in the outside air.
Cependant, il est à noter que les particules fines peuvent raccourcir la durée de vie du deuxième filtre 82 à haute performance. Dans ce cas, on peut le protéger en utilisant un filtre à air 83 en cas de détection de particules fines à l’extérieur du véhicule 1. Par ailleurs, afin de limiter la pollution dans l’habitacle du véhicule 1 , il est avantageux de filtrer les polluants issus principalement de certains matériaux présents dans l’habitacle ou des passagers eux- mêmes. Pour cela, on utilise un deuxième système de filtrage 9. Pour filtrer les polluants gazeux de l’habitacle, le deuxième système de filtrage 9 comprend un filtre à air 91 couplé à un filtre 92 optionnel et apte à traiter uniquement les polluants gazeux présents dans l’habitacle. Ce dernier est constitué notamment de charbon actif, de MOF et/ou d’ autres absorbants. Le système de filtrage 9 n’est activé que lorsque le niveau de concentration des polluants gazeux est supérieur à une valeur seuil que l’homme du métier saura choisir. Le filtre 91 est un filtre à particules qui a pour objectif de protéger le filtre 92. Pour éviter d’embuer les vitres de l’habitacle lors de la mise en œuvre du recyclage de l’ air, des moyens de déshumidification 10 sont couplés audit système de gestion 2 et aptes à être activés lors de ladite mise en œuvre. However, it should be noted that fine particles can shorten the life of the second high performance filter 82. In this case, it can be protected by using an air filter 83 in the event of detection of fine particles outside the vehicle 1. Furthermore, in order to limit pollution in the passenger compartment of the vehicle 1, it is advantageous to filter pollutants mainly from certain materials present in the passenger compartment or from the passengers themselves. For this, a second filtering system 9 is used. To filter the gaseous pollutants from the passenger compartment, the second filtering system 9 comprises an air filter 91 coupled to an optional filter 92 and able to treat only the gaseous pollutants present in the passenger compartment. The latter consists in particular of activated carbon, MOF and / or other absorbents. The filtering system 9 is only activated when the level of concentration of gaseous pollutants is greater than a threshold value that those skilled in the art will be able to choose. The filter 91 is a particulate filter which aims to protect the filter 92. To avoid misting the windows of the passenger compartment during the implementation of the air recirculation, dehumidification means 10 are coupled to said. management system 2 and able to be activated during said implementation.
Ainsi, pour gérer la qualité de l’ air dans l’habitacle, le système de gestion 2 coopèrent avec les moyens de déshumidification 10, le premier et le deuxième système de filtrage 8 et 9. Thus, to manage the quality of the air in the passenger compartment, the management system 2 cooperates with the dehumidification means 10, the first and the second filtering system 8 and 9.
A cette fin, le système de gestion 2 comporte des moyens d’ acquisition 3 aptes à acquérir des données relatives à la pollution autour et à l’ intérieur du véhicule sur le trajet prédéterminé. Lesdites données peuvent être issues d’une première série Cx de capteurs externes Cxl , ... ,Cx4 aptes à mesurer des grandeurs physiques pouvant permettre par la suite de déterminer le niveau de pollution autour du véhicule 1. Ils sont installés en entrée d’ air ou à l’extérieur du véhicule 1 sur toute partie pouvant assurer un bon maintien des capteurs en position. Les moyens d’ acquisition 3 peuvent également acquérir des données issues d’une deuxième série CI de capteurs internes Cil , CI2 par exemple, aptes à mesurer des grandeurs physiques pouvant permettre par la suite de déterminer le niveau de pollution dans l’habitacle du véhicule 1. Enfin, pour déterminer le niveau de pollution sur un trajet prédéterminé, les moyens d’ acquisition 3 peuvent récupérer par un satellite 12 par exemple des données envoyées relatives à la météo, le trafic et le niveau de pollution sur différents points du trajet par exemple. Les données acquises sont ensuite envoyées à des moyens de calcul 4 aptes à déterminer le niveau de pollution de l’ air à l’ intérieur du véhicule mais aussi autour sur le trajet prédéterminé. To this end, the management system 2 comprises acquisition means 3 capable of acquiring data relating to the pollution around and inside the vehicle over the predetermined route. Said data can come from a first series Cx of external sensors Cxl, ..., Cx4 capable of measuring physical quantities which can subsequently make it possible to determine the level of pollution around the vehicle 1. They are installed at the inlet of the vehicle. air or outside the vehicle 1 on any part that can ensure good retention of the sensors in position. The acquisition means 3 can also acquire data from a second series CI of internal sensors Cil, CI2 for example, capable of measuring physical quantities which can subsequently make it possible to determine the level of pollution in the passenger compartment of the vehicle. 1. Finally, to determine the level of pollution on a predetermined route, the acquisition means 3 can retrieve by a satellite 12, for example, data sent relating to the weather, the traffic and the level of pollution at various points along the route. example. The acquired data are then sent to calculation means 4 capable of determining the level of air pollution inside the vehicle but also around it on the predetermined route.
Il est à noter que les données acquises sont stockées dans une mémoire 5 et mis à disposition des moyens de calcul 4. It should be noted that the acquired data are stored in a memory 5 and made available to the calculation means 4.
Pour améliorer la précision des résultats, les moyens de calcul 4 comprennent au moins une machine d’ apprentissage automatique 11. To improve the accuracy of the results, the calculation means 4 include at least one machine learning machine 11.
Ainsi, les moyens de calcul 4 élaborent une cartographie prédictive de la pollution de l’ air sur ledit trajet et l’envoient à des moyens de contrôle 6 aptes à mettre en œuvre le recyclage de l’ air présent dans l’habitacle en fonction de l’ évolution du niveau de pollution de l’ air présent autour et à l’ intérieur du véhicule sur ledit trajet. Thus, the calculation means 4 develop a predictive map of the air pollution on said path and send it to control means 6 capable of implementing the recycling of the air present in the passenger compartment as a function of. the evolution of the level of pollution of the air present around and inside the vehicle on said route.
A titre d’exemple, si la cartographie prédictive indique que sur le trajet, la mise en œuvre du recyclage est souhaitable sur une portion donnée, les moyens de contrôle 6 envoient un signal de commande au volet mobile 7 avant que le véhicule 1 circule sur cette portion afin d’ assurer, avant la mise en œuvre du recyclage, un bon niveau d’ oxygène, d’eau et de dioxyde de carbone. For example, if the predictive mapping indicates that on the journey, the implementation of recycling is desirable on a given portion, the control means 6 send a control signal to the movable shutter 7 before the vehicle 1 is running on this portion in order to ensure, before the implementation of the recycling, a good level of oxygen, water and carbon dioxide.
De même, lorsque la cartographie prédictive indique qu’on se trouve dans une zone moyennement polluée et que le niveau de pollution sera élevé sur une portion du trajet à parcourir, les moyens de contrôle 6 ouvrent le volet mobile 7 dans ladite zone moyennement polluée, activent le premier système de filtrage 8, le deuxième système de filtrage 9, et les moyens de déshumidification 10. Bien évidemment, les moyens de contrôle 6 peuvent également choisir de mettre en œuvre un recyclage partiel et ainsi mettre les volets d’ entrée 7 dans une position intermédiaire. Likewise, when the predictive mapping indicates that one is in a moderately polluted zone and that the level of pollution will be high over a portion of the route to be traveled, the control means 6 open the movable shutter 7 in said moderately polluted zone, activate the first filtering system 8, the second filtering system 9, and the dehumidification means 10. Obviously, the control means 6 can also choose to implement a partial recycling and thus put the inlet flaps 7 in. an intermediate position.
Ainsi, grâce à la prédictivité des niveaux de pollution sur le trajet prédéterminé, le pilotage du volet mobile 7, des différents systèmes de filtrage 8, 9, et des moyens de déshumidification 10 par le système de gestion 2, il est possible d’ assurer une bonne qualité de l’ air présent dans l’habitacle et le confort thermique sans augmenter significativement la consommation du véhicule 1. Par ailleurs, l’invention n’ est pas limitée à ces modes de réalisation et de mise en œuvre mais en embrasse toutes les variantes. Par exemple, le système de gestion 2 pourrait piloter tout module du véhicule 1 pouvant influencer la qualité de l’ air présent dans l’habitacle. Thus, thanks to the predictivity of the pollution levels on the predetermined path, the control of the movable shutter 7, of the various filtering systems 8, 9, and of the dehumidification means 10 by the management system 2, it is possible to ensure good quality of the air present in the passenger compartment and thermal comfort without significantly increasing vehicle consumption 1. Furthermore, the invention is not limited to these embodiments and implementations but encompasses all the variants thereof. For example, the management system 2 could control any module of the vehicle 1 that can influence the quality of the air present in the passenger compartment.
