DESCRIPTION DESCRIPTION
Titre : Procédé et dispositif d’alerte de sous gonflage de pneus d’un véhicule Title: Method and device for warning of under-inflated vehicle tires
La présente invention revendique la priorité de la demande française 2210933 déposée le 21.10.2022 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of French application 2210933 filed on 10/21/2022, the content of which (text, drawings and claims) is here incorporated by reference.
Domaine technique Technical area
[0001] L’invention concerne l’alerte de sous gonflage de pneus d’un véhicule. [0001] The invention relates to the alert of under-inflation of vehicle tires.
Arrière-plan technologique Technology background
[0002] Il est préconisé de vérifier régulièrement la pression de ses pneumatiques, et surtout avant un long trajet où le risque d’explosion du pneumatique et donc d’accident est d’autant plus élevé. On préconise par ailleurs un contrôle mensuel. [0002] It is recommended to regularly check the pressure of your tires, and especially before a long journey where the risk of tire explosion and therefore accident is even higher. We also recommend a monthly check.
[0003] La pression à mettre dans chaque pneumatique (à minima identique pour les roues d’un même essieu) est précisé sur une plaque fixée sur le bas de porte conducteur. Cette plaque précise notamment les pressions des pneus, à vide et en charge et la pression de gonflage de la roue de secours. [0003] The pressure to be put in each tire (at least identical for the wheels of the same axle) is specified on a plate fixed to the bottom of the driver's door. This plate specifies in particular the tire pressures, empty and loaded, and the inflation pressure of the spare wheel.
[0004] On préconise aussi généralement que le gonflage de pneumatique doit être réalisée avec des pneus « froids » (véhicule à l'arrêt pendant 1 heure ou après un trajet de moins de 10 km à vitesse modérée). Sinon, on ajoute 0,3 bar aux pressions indiquées sur l'étiquette. En outre lorsque l’on roule à pleine charge, il est préconisé d’ajouter 0,2 bar. Si l’on tracte une caravane, il est préconisé d’ajouter 0,4 bar aux pneus arrière. [0004] It is also generally recommended that tire inflation must be carried out with “cold” tires (vehicle stationary for 1 hour or after a journey of less than 10 km at moderate speed). Otherwise, add 0.3 bar to the pressures indicated on the label. In addition, when driving at full load, it is recommended to add 0.2 bar. If you are towing a caravan, it is recommended to add 0.4 bar to the rear tires.
[0005] La détermination d’une pression adéquate des pneumatiques du véhicule est donc complexe et peut nécessiter une assistance pour être correctement réalisée. [0005] Determining adequate vehicle tire pressure is therefore complex and may require assistance to be correctly carried out.
[0006] Pour signaler un problème de pression sur les pneus d’un véhicule, il est connu de présenter une alerte tel qu’un témoin et/ou un message affiché dans l’écran du combiné du véhicule. Si l’utilisateur souhaite en savoir plus ou s’il souhaite obtenir une aide il lui faut alors manuellement effectuer des opérations supplémentaires sur l’une des interfaces du véhicule. Ces opérations supplémentaires peuvent s’avérer fastidieuse si bien que le conducteur peut être tenté de renoncer à les effectuer.[0006] To signal a pressure problem on the tires of a vehicle, it is known to present an alert such as a warning light and/or a message displayed in the vehicle's instrument panel screen. If the user wishes to know more or if he wishes to obtain help, he must then manually carry out additional operations on one of the vehicle interfaces. These additional operations can prove tedious so that the driver may be tempted to forgo carrying them out.
Résumé de l’invention Summary of the invention
[0007] Un objet de la présente invention est de proposer une solution aux inconvénients précités et en particulier de faciliter l’accès à des informations du véhicule pour réduire le temps nécessaire pour remédier au problème de sous gonflage des pneus. [0007] An object of the present invention is to propose a solution to the aforementioned drawbacks and in particular to facilitate access to vehicle information to reduce the time necessary to remedy the problem of under-inflating tires.
[0008] A cet effet, l’invention a pour objet un procédé d’alerte de sous-gonflage de pneus d’un véhicule comportant un écran tactile affichant une interface graphique, ladite interface graphique comprenant un premier objet graphique affiché en permanence, lorsque l’écran est allumé, et affichant au moins la vitesse du véhicule et au moins un voyant relatif à une fonction d’alerte de sous-gonflage des pneus du véhicule, ladite interface comportant en outre au moins un deuxième objet graphique affiché de façon éphémère, ledit procédé comportant des étapes de : [0008] To this end, the subject of the invention is a method for alerting the under-inflation of tires of a vehicle comprising a touch screen displaying a graphical interface, said graphical interface comprising a first graphical object permanently displayed, when the screen is on, and displaying at least the speed of the vehicle and at least one light relating to an under-inflation alert function of the vehicle's tires, said interface further comprising at least a second graphic object displayed ephemerally , said method comprising steps of:
- en réponse à la réception d’un signal indiquant un sous-gonflage d’un pneu, modification de l’apparence du voyant relatif à la pression des pneus, de façon à signaler le sous gonflage à un conducteur, - in response to receipt of a signal indicating under-inflation of a tire, modification of the appearance of the warning light relating to tire pressure, so as to signal the under-inflation to a driver,
- en réponse à la détection d’un appui sur le voyant, commande de l’affichage d’un troisième objet graphique recouvrant le deuxième objet graphique, ledit troisième objet graphique comportant des informations relatives au sous-gonflage et un premier bouton, - in response to the detection of pressing the indicator light, controls the display of a third graphic object covering the second graphic object, said third graphic object comprising information relating to under-inflation and a first button,
- en réponse à la détection d’un appui sur le premier bouton, commande de l’affichage d’une application de navigation indiquant au moins un point de gonflage de pneus. - in response to the detection of a press on the first button, controls the display of a navigation application indicating at least one tire inflation point.
[0009] L’invention permet de réduire le nombre d’étapes nécessaires pour accéder à une information. En appuyant sur le symbole de l’alerte, l’utilisateur peut obtenir directement et sur le même écran une information sur l’alerte et un raccourci permettant de lancer une application de navigation vers une station de gonflage. [0009] The invention makes it possible to reduce the number of steps necessary to access information. By pressing the alert symbol, the user can directly obtain information on the alert and a shortcut to launch a navigation application to an inflation station on the same screen.
[00010] Avantageusement, ledit troisième objet graphique comporte en outre un deuxième bouton, ledit procédé comportant en outre une étape de : - en réponse à la détection 44 d’un appui sur le deuxième bouton, commande d’une réinitialisation de la fonction d’alerte de sous-gonflage. [00010] Advantageously, said third graphic object further comprises a second button, said method further comprising a step of: - in response to detection 44 of pressing the second button, commands a reset of the under-inflation alert function.
[00011] Avantageusement, le deuxième objet graphique est relatif à une application choisie parmi : une application de navigation, une application de lecture de contenus multimédia, une application de paramétrage de fonctions du véhicule. [00011] Advantageously, the second graphic object relates to an application chosen from: a navigation application, an application for reading multimedia content, an application for configuring vehicle functions.
[00012] L’invention concerne aussi un programme d'ordinateur comprenant des instructions qui, lorsque le programme est exécuté par un ordinateur, conduisent celui-ci à mettre en oeuvre le procédé selon l’invention. [00012] The invention also relates to a computer program comprising instructions which, when the program is executed by a computer, lead it to implement the method according to the invention.

La planche de bord comporte, du côté conducteur, qui est dans l'exemple représenté sur le côté gauche du véhicule, un volant 12. [00020] [Fig. 5] illustrates a second example of a man-machine interface according to the invention. [00021] Figure 1 shows a vehicle interior and in particular a dashboard. The dashboard comprises, on the driver's side, which is in the example shown on the left side of the vehicle, a steering wheel 12.
[00022] La planche de bord comporte, dans une partie centrale un écran 11. 11 s’agit d’un écran tactile. [00022] The dashboard includes, in a central part, a screen 11. 11 is a touch screen.
[00023] Le dispositif selon l’invention permet de fournir une alerte de sous gonflage de pneus d’un véhicule. Il est en particulier configuré pour commander l’affichage sur l’écran 11 et, notamment pour commander l’affichage d’une pluralité d’objets graphiques d’affichage de données appelés « widgets » sur l’écran 11 . [00023] The device according to the invention makes it possible to provide an alert of under-inflated tires of a vehicle. It is in particular configured to control the display on the screen 11 and, in particular to control the display of a plurality of graphic data display objects called “widgets” on the screen 11.
[00024] La figure 3 montre un exemple d’un affichage d’une pluralité d’objets graphiques 31 , 32 sur l’écran 12. [00024] Figure 3 shows an example of a display of a plurality of graphic objects 31, 32 on the screen 12.
[00025] Dans cet exemple, l’écran 11 affiche : [00025] In this example, screen 11 displays:
- Un premier objet graphique 31 affichant des informations telles qu’une vitesse de déplacement du véhicule, une valeur de vitesse limite pour le limiteur de vitesse, une limitation de vitesse détectée sur le segment de route parcouru par le véhicule, et- A first graphic object 31 displaying information such as a speed of movement of the vehicle, a speed limit value for the speed limiter, a speed limit detected on the road segment traveled by the vehicle, and
- Un deuxième objet graphique 32 affichant des informations de guidage. - A second graphic object 32 displaying guidance information.
[00026] Le premier objet graphique 31 affiché en permanence, lorsque l’écran 11 est allumé, et que le véhicule est dans une phase roulage (autrement dit le véhicule est en cours de déplacement). Le premier objet graphique 31 affichant au moins la vitesse du véhicule et un voyant 31 .1 . Le voyant 31 .1 , est relatif à une fonction d’alerte de sous-gonflage des pneus du véhicule. [00026] The first graphic object 31 permanently displayed, when the screen 11 is lit, and the vehicle is in a driving phase (in other words the vehicle is moving). The first graphic object 31 displaying at least the speed of the vehicle and an indicator light 31.1. Light 31.1 relates to an under-inflated vehicle tire warning function.
[00027] Le deuxième objet graphique 32 est affiché de façon éphémère, autrement dit, il peut être remplacé par un autre objet graphique ou bien recouvert par une fenêtre dite pop-up. The second graphic object 32 is displayed ephemerally, in other words, it can be replaced by another graphic object or covered by a so-called pop-up window.
[00028] En référence à la figure 4, le procédé selon l’invention comporte les étapes suivantes. [00028] With reference to Figure 4, the method according to the invention comprises the following steps.
[00029] Dans une première étape, le dispositif selon l’invention reçoit 41 un signal indiquant un sous-gonflage d’au moins un pneu du véhicule. [00029] In a first step, the device according to the invention receives 41 a signal indicating under-inflation of at least one tire of the vehicle.
[00030] Dans une deuxième étape, le dispositif commande la modification 42 l’apparence du voyant 31 .1 relatif au sous-gonflage, de façon à signaler la défaillance à un conducteur. Cette modification d’apparence prend par exemple la forme d’un changement de couleur, d’un changement d’intensité de la luminosité, d’un changement de la transparence du voyant ou d’une combinaison de ces changements. [00030] In a second step, the device controls the modification 42 of the appearance of the warning light 31.1 relating to under-inflation, so as to signal the failure to a driver. This modification of appearance takes for example the form of a change in color, a change in brightness intensity, a change in the transparency of the indicator or a combination of these changes.
[00031] Dans une troisième étape, le dispositif détecte 43 un appui sur le voyant 311 dont l’apparence a été modifié. [00031] In a third step, the device detects 43 pressing the indicator light 311, the appearance of which has been modified.
[00032] Dans une quatrième étape, en réponse à la détection 43, le dispositif commande 44 l’affichage d’un troisième objet graphique recouvrant le deuxième objet graphique 32. Le troisième objet graphique comporte des informations relatives à la défaillance et un premier bouton. [00032] In a fourth step, in response to detection 43, the device 44 controls the display of a third graphic object covering the second graphic object 32. The third graphic object includes information relating to the failure and a first button .
[00033] Dans une cinquième étape, en réponse à la détection 45 d’un appui sur le premier bouton, le dispositif commande 46 l’affichage d’une application de navigation indiquant au moins un point de gonflage de pneus. L’application utilise la localisation du véhicule, déterminé à l’aide du GPS, pour identifier les stations de gonflage les plus proches. [00033] In a fifth step, in response to the detection 45 of a press on the first button, the device controls 46 the display of a navigation application indicating at least one tire inflation point. The app uses the vehicle's location, determined using GPS, to identify the nearest inflation stations.
[00034] Avantageusement, le troisième objet graphique comporte en outre un deuxième bouton, ledit procédé comportant en outre une étape de, en réponse à la détection 44 d’un appui sur le deuxième bouton, commande d’une réinitialisation de la fonction d’alerte de sous-gonflage. Cette caractéristique permet de réduire le nombre d’actions à réaliser pour accéder à la commande de réinitialisation. En effet, habituellement, accéder au bon sous-menu de reset de la pression n’est pas forcément simple et ergonomique. Sans cette réinitialisation, il arrive que l’alerte ne soit pas levée, même si la pression des pneus est ajustée. Ne pas trouver cette commande par manque d’ergonomie est une donc gêne pour l’utilisateur. [00034] Advantageously, the third graphic object further comprises a second button, said method further comprising a step of, in response to detection 44 of pressing the second button, controlling a reset of the function under-inflation alert. This feature reduces the number of actions required to access the reset command. In fact, usually, accessing the correct pressure reset submenu is not necessarily simple and ergonomic. Without this reset, the alert may not be raised, even if the tire pressure is adjusted. Not finding this command due to lack of ergonomics is therefore an inconvenience for the user.
[00035] La figure 5 montre un deuxième exemple d’un affichage d’une pluralité d’objets graphiques 31 , 32 sur l’écran 12. Ce deuxième exemple est similaire au premier mais il montre en outre l’affichage d’un troisième objet graphique 33 correspondant à une alerte de sous-gonflage. Le troisième objet 33 est, dans l’exemple, une pop-up. Cette pop-up comprend un premier 51 et un deuxième 52 boutons. [00035] Figure 5 shows a second example of a display of a plurality of graphic objects 31, 32 on the screen 12. This second example is similar to the first but it also shows the display of a third graphic object 33 corresponding to an under-inflation alert. The third object 33 is, in the example, a pop-up. This pop-up includes a first 51 and a second 52 buttons.
