L'invention concerne les véhicules, éventuellement de type terrestre, et plus précisément les dispositifs qui sont destinés à aider les conducteurs pendant les phases de stationnement de leurs véhicules. The invention relates to vehicles, possibly of terrestrial type, and more specifically the devices which are intended to help drivers during the parking phases of their vehicles.
Certains véhicules, généralement de type automobile, sont équipés d'un dispositif d'aide au stationnement chargé de contrôler les manœuvres pendant les phases de stationnement, afin qu'ils puissent être garés sur une zone de stationnement ou sortis d'une zone de stationnement sans intervention de leur conducteur.  Some vehicles, generally of automobile type, are equipped with a parking assist device to control the maneuvers during the parking phases, so that they can be parked in a parking area or out of a parking area without the intervention of their driver.
Il est prévu d'activé le dispositif d'aide au stationnement avec une commande dédiée. Généralement, l'exécution d'une manœuvre n'est effective qu'après une confirmation du conducteur.  It is planned to activate the parking assistance device with a dedicated command. Generally, the execution of a maneuver is effective only after a confirmation of the driver.
Une telle confirmation peut faire partie d'une procédure assez longue comprenant également l'activation de la fonction d'aide au stationnement, l'actionnement correct du clignotant pour signaler le bon côté du stationnement (ou de sortie de la zone de stationnement), le maintien de la vitesse du véhicule en-dessous d'un seuil prédéfini, et l'enclenchement de la marche arrière ou du neutre au bon moment, si bien qu'il est assez facile de se tromper lorsqu'on la réalise (en particulier si l'on est pressé, par exemple du fait que l'on gêne un tiers).  Such a confirmation can be part of a rather long procedure also including the activation of the parking assistance function, the correct activation of the flashing to signal the right side of the parking (or exit of the parking area), maintaining the speed of the vehicle below a predefined threshold, and engaging the reverse or neutral at the right moment, so that it is easy enough to go wrong when it is done (especially if one is in a hurry, for example because one hinders a third).

D'autres caractéristiques et avantages de l'invention apparaîtront à l'examen de la description détaillée ci-après, et des dessins annexés, sur lesquels: Other features and advantages of the invention will appear on examining the detailed description below, and the accompanying drawings, on which:
- la figure 1 illustre schématiquement et fonctionnellement, dans une vue du dessus, un exemple de véhicule automobile équipé d'un exemple de réalisation de dispositif d'aide à l'activation selon l'invention,  FIG. 1 schematically and functionally illustrates, in a view from above, an example of a motor vehicle equipped with an exemplary embodiment of an activation aid device according to the invention,

- les figures 3a, 3b et 3c illustrent chacune schématiquement un écran sur lequel est affiché un exemple de liste de conditions d'activation. FIGS. 3a, 3b and 3c each schematically illustrate a screen on which is displayed an exemplary list of activation conditions.
Les dessins annexés pourront non seulement servir à compléter l'invention, mais aussi contribuer à sa définition, le cas échéant.  The attached drawings may not only serve to complete the invention, but also contribute to its definition, if any.
L'invention a notamment pour but de proposer un dispositif D destiné à aider un conducteur lors de l'activation d'un mode d'assistance de son véhicule V.  The object of the invention is notably to propose a device D intended to assist a driver when activating an assistance mode of his vehicle V.
Dans ce qui suit, on considère, à titre d'exemple non limitatif, que le véhicule V est de type automobile. Il s'agit par exemple d'une voiture, d'un autocar, d'un camion ou d'un véhicule utilitaire. Mais l'invention n'est pas limitée à ce type de véhicule. Elle concerne en effet tout type de véhicule terrestre ou maritime (ou fluvial) pouvant effectuer des déplacements et des manœuvres sur le sol ou sur l'eau et pouvant être garé dans une zone de stationnement ou sorti d'une zone de stationnement sans intervention du conducteur.  In what follows, it is considered, by way of non-limiting example, that the vehicle V is automotive type. This is for example a car, a coach, a truck or a commercial vehicle. But the invention is not limited to this type of vehicle. It concerns any type of land or sea (or river) vehicle that can make movements and maneuvers on the ground or on the water and can be parked in a parking zone or out of a parking area without intervention of the driver.
On considère aussi que le mode d'assistance à la conduite est un mode d'aide au stationnement automatique contrôlant le déplacement longitudinal du véhicule et son déplacement latéral et que le dispositif d'assistance à la conduite est un dispositif d'aide au stationnement. Mais l'invention n'est pas limitée à ce type de mode d'assistance. Elle concerne en effet tout type de mode d'assistance nécessitant une pluralité de conditions d'activation.  It is also considered that the driving assistance mode is an automatic parking assistance mode controlling the longitudinal displacement of the vehicle and its lateral displacement and that the driving assistance device is a parking aid device. But the invention is not limited to this type of assistance mode. It concerns indeed any type of assistance mode requiring a plurality of activation conditions.
On a schématiquement et fonctionnellement représenté sur la figure 1 un exemple de véhicule automobile V équipé d'un exemple de réalisation d'un dispositif d'aide au stationnement D selon l'invention. On notera que dans cet exemple non limitatif le véhicule automobile V est une voiture comprenant des parties avant PV et arrière PR, et un réseau de communication RC, éventuellement de type multiplexé et permettant à des équipements électroniques embarqués (et notamment l'ordinateur de bord), qui sont connectés à lui, d'échanger des informations et instructions. FIG. 1 shows schematically and functionally an example of a motor vehicle V equipped with an exemplary embodiment of a parking aid device D according to the invention. Note that in this non-limiting example the motor vehicle V is a car comprising front portions PV and rear PR, and an RC communication network, possibly multiplexed type and allowing equipment embedded electronics (and in particular the on-board computer), which are connected to it, to exchange information and instructions.
Comme illustré, le dispositif d'aide au stationnement D comprend au moins des moyens de contrôle MC.  As illustrated, the parking aid device D comprises at least control means MC.
Dans l'exemple non limitatif illustré sur la figure 1 , le dispositif (d'aide au stationnement) D est un équipement indépendant couplé au réseau de communication RC afin de récupérer des données et instructions qui le concernent. Mais cela n'est pas obligatoire. Il pourrait en effet faire partie d'un autre équipement, comme par exemple l'ordinateur de bord ou un calculateur ou encore un système global d'aide à la conduite et aux manœuvres offrant des fonctions d'aide complémentaires, comme par exemple la détection d'objets susceptibles de constituer des obstacles, la détection de franchissement de ligne, la correction de trajectoire, l'adaptation de la vitesse du véhicule V en fonction de la distance qui le sépare d'un véhicule qui le précède, la fourniture d'images de zones qui sont situées sur les côtés longitudinaux et/ou la partie avant PV et/ou la partie arrière PR du véhicule V, ou l'assistance lors d'une manœuvre dans un passage délicat. Par conséquent, le dispositif D peut être réalisé sous la forme de modules logiciels (ou informatiques ou encore « software »), ou bien d'une combinaison de circuits électroniques (ou « hardware ») et de modules logiciels.  In the nonlimiting example illustrated in FIG. 1, the device (parking aid) D is an independent device coupled to the communication network RC in order to retrieve data and instructions that concern it. But this is not obligatory. It could indeed be part of other equipment, such as the on-board computer or a computer or a global system for driving assistance and maneuvers offering additional assistance functions, such as detection objects likely to constitute obstacles, the line crossing detection, the course correction, the adaptation of the speed of the vehicle V according to the distance which separates it from a vehicle which precedes it, the supply of images of areas which are located on the longitudinal sides and / or the front part PV and / or the rear part PR of the vehicle V, or the assistance during a maneuver in a delicate passage. Therefore, the device D can be realized in the form of software modules (or computer or "software"), or a combination of electronic circuits (or "hardware") and software modules.
On notera également que le dispositif D peut également et éventuellement comprendre des moyens d'analyse MA agencés pour analyser des images numériques acquises par des moyens d'acquisition d'images Ml qui équipent le véhicule V, afin de détecter des zones de stationnement ZS situées dans l'environnement immédiat du véhicule V.  It will also be noted that the device D may also and possibly also comprise analysis means MA arranged for analyzing digital images acquired by image acquisition means M1 which equip the vehicle V, in order to detect parking zones ZS located in the immediate environment of the V vehicle.
L'invention concerne aussi un procédé d'aide à l'activation d'au moins un mode d'assistance à la conduite d'un véhicule par un conducteur. La figure 2 illustre un logigramme représentant le procédé selon l'invention. The invention also relates to a method of assisting the activation of at least one mode of assistance to the driving of a vehicle by a driver. FIG. 2 illustrates a logic diagram representing the method according to the invention.
Ledit procédé est mis en œuvre par un dispositif d'assistance à la conduite par exemple le dispositif d'aide au stationnement D. Said method is implemented by a driving assistance device, for example the parking aid device D.
Ledit dispositif est apte à activer ledit mode d'assistance seulement si une pluralité de conditions d'activation est respectée. On suppose qu'il existe quatre conditions d'activation : Said device is able to activate said assistance mode only if a plurality of activation conditions is respected. It is assumed that there are four activation conditions:
- le volant est relâché par le conducteur ; - the steering wheel is released by the driver;
- le conducteur appuie sur la pédale de frein ; - the driver presses on the brake pedal;
- la boîte de vitesse est en position neutre ; - the gearbox is in neutral position;
- le clignotant est enclenché. - the flashing light is on.
Le procédé comporte une étape de réception (21 ) d'une commande d'activation dudit mode d'assistance, par le dispositif D.  The method comprises a step of receiving (21) an activation command of said assistance mode, by the device D.
Le dispositif D intervient lorsqu'une aide au stationnement est requise par le conducteur, par exemple par sélection d'un élément dans un menu ou un sous-menu affichable sur un écran d'affichage EC du véhicule V, comme par exemple le combiné central (implanté en position centrale dans la planche de bord PB), ou par appui sur un bouton dédié, présent dans la planche de bord PB ou la console centrale du véhicule V, ou encore par actionnement d'une manette dédiée ou d'un actionneur dédié faisant partie d'une manette du véhicule V.  The device D intervenes when a parking aid is required by the driver, for example by selecting an item in a menu or a submenu that can be displayed on an EC display screen of the vehicle V, such as for example the central handset. (centrally located in the dashboard PB), or by pressing a dedicated button, present in the dashboard PB or the center console of the vehicle V, or by operating a dedicated controller or an actuator dedicated part of a lever of the vehicle V.
Le procédé comporte en outre, en réponse à la réception de la commande des étapes de : The method further comprises, in response to receiving the command, steps of:
- Vérification 22 si les conditions d'activation sont respectées,  - Verification 22 if the activation conditions are met,
- Commande 23 d'un affichage des conditions d'activation, ledit affichage comportant au moins une indication permettant de distinguer des conditions respectées d'activation et des conditions d'activation non respectées.  - Command 23 of a display of the activation conditions, said display comprising at least one indication to distinguish between the conditions of activation and activation conditions not respected.
On notera que les informations de (i) présence (ou d'absence) des mains sur le volant, (ii) appuie (ou non) sur la pédale de frein, (iii) position de la boîte de vitesse (iv), position du clignotant (enclenché ou non) sont accessibles via le réseau de communication RC. Note that the information of (i) presence (or absence) of hands on the steering wheel, (ii) presses (or not) on the brake pedal, (iii) position of the gearbox (iv), position flashing light (on or off) can be accessed via the RC communication network.
Par exemple, les moyens de contrôle MC peuvent être agencés, dès qu'une de ces informations évoluent, pour évaluer si la condition d'activation correspondante est vérifiée. On comprendra que la condition qui est associée à la présence des mains sur le volant est dite remplie lorsque l'information accessible sur le réseau RC et reçue par les moyens de contrôle MC est comparée à un état enregistré et que la comparaison est positive. For example, the control means MC can be arranged, as soon as one of these information changes, to evaluate whether the corresponding activation condition is verified. It will be understood that the condition which is associated with the presence of hands on the steering wheel is said to be fulfilled when the information accessible on the network RC and received by the control means MC is compared with a registered state and the comparison is positive.
Lorsque cette aide est requise, les moyens de contrôle MC sont agencés (ou conçus) pour déclencher un affichage de la liste de conditions sur un écran EC présent dans le véhicule V. Par exemple, on peut utiliser l'écran d'affichage EC du combiné central précité. Mais, on pourrait également envisager que cet écran d'affichage soit celui d'un équipement de communication mobile (de type smartphone) appartenant au conducteur, disposant d'une application d'aide au stationnement dédiée, et embarqué temporairement dans le véhicule V. Dans ce cas, le dispositif D échange avec cet équipement de communication mobile via un module de communication par voie d'ondes que comprend le véhicule V et qui est couplé au réseau de communication RC. When this assistance is required, the control means MC are arranged (or designed) to trigger a display of the list of conditions on an EC screen present in the vehicle V. For example, it is possible to use the EC display screen of the above-mentioned central handset.
