DOMAINE TECHNIQUE TECHNICAL AREA
Le domaine technique de la présente invention est celui des dispositifs de signalisation. Plus particulièrement, la présente invention concerne un dispositif de signalisation routière destiné à être porté par un conducteur de véhicule terrestre ou destiné à être adapté à un tel véhicule, ce véhicule étant de préférence un véhicule à deux roues.  The technical field of the present invention is that of signaling devices. More particularly, the present invention relates to a road signaling device intended to be carried by a land vehicle driver or intended to be adapted to such a vehicle, this vehicle preferably being a two-wheeled vehicle.
ÉTAT DE LA TECHNIQUE  STATE OF THE ART
Dans l’état de la technique, on connaît des dispositifs de signalisation lumineuse fonction du freinage d’un véhicule.  In the state of the art, light-signaling devices are known which function of the braking of a vehicle.
Ces dispositifs permettent à des feux stop de s’éclairer de façon variable en fonction du niveau de freinage constaté par un accéléromètre se trouvant dans la source de lumière.  These devices allow stop lights to illuminate in a variable manner depending on the braking level found by an accelerometer in the light source.
Mais, pour limiter le nombre et la gravité de leurs accidents, il conviendrait de rendre les conducteurs de véhicules à deux roues plus visibles, en disposant une source de lumière à une hauteur du sol plus élevée que celle des feux desdits véhicules, comme cela est le cas pour le troisième feu stop disposé sur le pare-brise arrière des véhicules à trois ou quatre roues.  But in order to limit the number and severity of their accidents, two-wheeled vehicle drivers should be made more visible by placing a source of light at a higher ground level than that of the lights of the said vehicles, as is the case for the third stop lamp placed on the rear windscreen of three or four-wheeled vehicles.
Ainsi, d’une part les conducteurs de véhicules à deux roues seraient visibles à travers une automobile intercalée entre un observateur et le feu stop dont il serait équipé et, d’autre part, la distance séparant ledit observateur dudit conducteur serait mieux appréciée par ledit observateur. En effet, il a été prouvé que l’œil humain évalue mieux la distance le séparant d’un objet comportant plusieurs lumières que celle le séparant d’un objet n’en comportant qu’une seule.  Thus, on the one hand, the drivers of two-wheeled vehicles would be visible through an automobile interposed between an observer and the stop light of which it would be equipped and, on the other hand, the distance separating said observer from said driver would be better appreciated by said observer. Indeed, it has been proved that the human eye better assesses the distance separating it from an object having several lights than that separating it from an object having only one.
En outre, ces dispositifs ne sont pas adaptés pour émettre, en cas d’accident, un signal distinct de celui émis pour le freinage, ce qui peut être préjudiciable pour l’intégrité physique du conducteur muni dudit dispositif.  In addition, these devices are not adapted to emit, in case of accident, a signal separate from that issued for braking, which can be detrimental to the physical integrity of the driver provided with said device.
Il existe un réel besoin de réaliser un dispositif de signalisation perfectionné résolvant les problèmes techniques susmentionnés.  There is a real need to realize an improved signaling device solving the aforementioned technical problems.

EXPOSÉ DE MODES DE RÉALISATION  DESCRIPTION OF EMBODIMENTS
La figure 1 représente, de façon schématique, un exemple de réalisation d’un circuit électronique d’un dispositif de signalisation 10 selon l’invention.  FIG. 1 schematically represents an exemplary embodiment of an electronic circuit of a signaling device 10 according to the invention.
Le dispositif 10 est destiné à être porté par un conducteur d’un véhicule terrestre, en particulier d’un véhicule à deux roues destiné à circuler sur la route, typiquement une moto ou un vélo.  The device 10 is intended to be worn by a driver of a land vehicle, in particular a two-wheeled vehicle intended to travel on the road, typically a motorcycle or a bicycle.
Typiquement, le dispositif 10 peut être fixé ou intégré à l’arrière d’un casque, d’une veste, d’un sac-à-dos, ou tout autre accessoire destiné à être porté par un conducteur de véhicule. De préférence, ce circuit est relié à la masse, c’est-à-dire à l’accessoire sur lequel il est fixé ou intégré.  Typically, the device 10 can be attached to or integrated into the back of a helmet, a jacket, a backpack, or any other accessory to be worn by a vehicle driver. Preferably, this circuit is connected to ground, that is to say the accessory on which it is attached or integrated.
Le dispositif 10 comporte un accéléromètre 30, au moins une, ici deux, batterie(s) d’accumulateurs électrochimiques Bl et B2, une première source de lumière 50 constituée ici de six LEDs (LED1 - LED6), un moyen de communication sans fil 40 destiné à émettre un signal d’alerte, et une unité de contrôle 20.  The device 10 comprises an accelerometer 30, at least one, here two, battery (s) of electrochemical accumulators B1 and B2, a first light source 50 consisting here of six LEDs (LED1 - LED6), a means of wireless communication 40 for transmitting an alert signal, and a control unit 20.
Dans une première variante, la source de lumière est constituée d’une pluralité de LEDs, par exemple huit.  In a first variant, the light source consists of a plurality of LEDs, for example eight.
Typiquement, cette source de lumière 50 est de couleur normalisée, c’est-à-dire rouge.  Typically, this light source 50 is of standardized color, that is to say red.
Dans une deuxième variante, la source de lumière est constituée d’un écran lumineux. De préférence, les batteries Bl et B2 présentent chacune une tension nominale de l’ordre de 3,7 volts.  In a second variant, the light source consists of a luminous screen. Preferably, the batteries B1 and B2 each have a nominal voltage of the order of 3.7 volts.
Dans l’exemple, le moyen de communication sans fil 40 est connecté à une entrée A3 de l’unité de contrôle 20.  In the example, the wireless communication means 40 is connected to an input A3 of the control unit 20.
Dans l’exemple, la batterie Bl est connectée, via un transistor Ql et six résistances Rl, R2, R3, R4, R5 et R6, aux six LEDs (LED1 - LED6) de la source de lumière 50 pour les alimenter en électricité.  In the example, the battery B1 is connected via a transistor Q1 and six resistors R1, R2, R3, R4, R5 and R6 to the six LEDs (LED1 - LED6) of the light source 50 to supply them with electricity.
De préférence, les résistances Rl, R2, R3, R4, R5 et R6 sont de l’ordre de 68 ohms.  Preferably, the resistors R1, R2, R3, R4, R5 and R6 are of the order of 68 ohms.
Dans l’exemple, une sortie Dl l de l’unité de contrôle 20 est connectée, via une résistance R7, le transistor Ql et les six résistances Rl, R2, R3, R4, R5 et R6, aux six LEDs (LED1 - LED6) de la source de lumière 50.

Dans l’exemple, la batterie B2 est connectée à une entrée VIN de l’unité de contrôle 20, au moyen de communication sans fil 40 et à l’accéléromètre 30 pour les alimenter en électricité.  In the example, the battery B2 is connected to a VIN input of the control unit 20, the wireless communication means 40 and the accelerometer 30 to supply electricity.
L’unité de contrôle 20 est destinée à activer la source de lumière 50 lorsque l’accéléromètre 30 mesure une décélération supérieure ou égale à un premier seuil prédéfini de décélération, appelé seuil de freinage.  The control unit 20 is intended to activate the light source 50 when the accelerometer 30 measures a deceleration greater than or equal to a first predefined deceleration threshold, called the braking threshold.
Aussi, l’unité de contrôle 20 est destinée à activer le moyen de communication 40 lorsque l’accéléromètre 30 mesure une décélération supérieure ou égale à un deuxième seuil prédéfini de décélération, appelé seuil d’accident.  Also, the control unit 20 is intended to activate the communication means 40 when the accelerometer 30 measures a deceleration greater than or equal to a second predefined deceleration threshold, called the accident threshold.
Dans un exemple, le moyen de communication 40 émet le signal d’alerte via un réseau de télécommunication, par exemple GSM. Ainsi, les secours, et éventuellement au moins un proche du conducteur, sont avertis dès que le dispositif 10 subit un choc, c’est-à-dire dès que ledit conducteur est victime d’un accident.  In one example, the communication means 40 transmits the alert signal via a telecommunications network, for example GSM. Thus, rescuers, and possibly at least one close to the driver, are notified as soon as the device 10 is shocked, that is to say, as soon as said driver is the victim of an accident.
Dans une variante, le moyen de communication 40 émet le signal d’alerte via une application dédiée d’un téléphone mobile du conducteur. Dans ce cas, le moyen de communication 40 fonctionne par exemple par Wi-Fi (Wireless Fidelity, en langue anglaise), Bluetooth, ou par communication en champ propre (CCP), etc.  In a variant, the communication means 40 transmits the alert signal via a dedicated application of a mobile phone of the driver. In this case, the communication means 40 operates for example by Wi-Fi (Wireless Fidelity, in English), Bluetooth, or by communication in clean field (CCP), etc.
Typiquement, l’unité de contrôle 20 est de type processeur, microcontrôleur, PLD (programmable logic device, en langue anglaise), FPGA (fïeld-programmable gâte array, en langue anglaise), EPLD (erasable programmable logic device, en langue anglaise), CPLD (complex programmable logic device en langue anglaise), PAL (programmable array logic, en langue anglaise), ou PLA (programmable logic array, en langue anglaise). Typically, the control unit 20 is of the processor type, microcontroller, PLD (programmable logic device, in English language), FPGA (programmable-field programmable array, in English language), EPLD (erasable programmable logic device, in English language) , PLC programmable logic device (CPLD), PAL (programmable array logic, in English language), or PLA (programmable logic array, in English language).
De préférence, le dispositif 10 comporte en outre un système de géolocalisation 60, par exemple de type GPS (Global Positioning System, en langue anglaise) destiné à mesurer les coordonnées géographiques dudit dispositif, le signal d’alerte contenant lesdites coordonnées géographiques.  Preferably, the device 10 further comprises a geolocation system 60, for example of GPS (Global Positioning System) type for measuring the geographic coordinates of said device, the alert signal containing said geographical coordinates.
Dans l’exemple, la baterie B2 est connectée au système de géolocalisation 60 qui est lui-même connecté à une entrée A4 de l’unité de contrôle 20.  In the example, the battery B2 is connected to the geolocation system 60 which is itself connected to an input A4 of the control unit 20.
Dans un exemple, le dispositif 10 comporte une deuxième source de lumière (non représentée sur la figure 1). L’unité de contrôle 20 est alors en outre destinée à activer cette deuxième source de lumière lorsque l’accéléromètre 30 mesure une décélération supérieure ou égale au deuxième seuil prédéfini de décélération. Dans cas, la deuxième source de lumière est préférentiellement de couleur orange et fonctionne en clignotement. In one example, the device 10 has a second light source (not shown in Figure 1). The control unit 20 is then further intended to activate this second light source when the accelerometer 30 measures a deceleration greater than or equal to the second predefined deceleration threshold. In case, the second light source is preferably orange and operates in a flash.
De préférence, l’accéléromètre 30 est électronique et réalise ses mesures selon trois axes orthogonaux X, Y et Z. Dans ce cas, l’accéléromètre 30 comporte une sortie pour communiquer les mesures de chaque axe X, Y et Z, chacune des sorties étant connectée par une liaison fïlaire à une entrée distincte A0, Al et A2, respectivement, de l’unité de contrôle 20.  Preferably, the accelerometer 30 is electronic and performs its measurements along three orthogonal axes X, Y and Z. In this case, the accelerometer 30 includes an output for communicating the measurements of each axis X, Y and Z, each of the outputs being connected by a wire link to a separate input A0, A1 and A2, respectively, of the control unit 20.
Dans ce cas, l’unité de contrôle 20 est en outre destinée à activer le moyen de communication 40 et/ou la deuxième source de lumière lorsque l’accéléromètre 30 mesure, selon au moins un des axes X, Y et Z, un nombre basculements entre accélération et décélération supérieur ou égal à un seuil de nombre de basculements prédéfini, dans un laps de temps prédéfini.  In this case, the control unit 20 is also intended to activate the communication means 40 and / or the second light source when the accelerometer 30 measures, according to at least one of the X, Y and Z axes, a number switching between acceleration and deceleration greater than or equal to a predefined number of failover thresholds, in a predefined period of time.
Dans un exemple, ce seuil de nombre de basculements est de 3 et ce laps de temps prédéfini est de 3 secondes.  In one example, this number of failover thresholds is 3 and this predefined period of time is 3 seconds.
Dans un exemple, le dispositif 10 comporte en outre une photodiode et une troisième source de lumière (non représentées sur la figure 1). L’unité de contrôle 20 est alors en outre destinée à activer cette troisième source de lumière lorsque cete photodiode mesure un rayonnement optique inférieur ou égal à un seuil prédéfini de rayonnement optique, c’est-à-dire lorsque la luminosité extérieure devient faible.  In one example, the device 10 further comprises a photodiode and a third light source (not shown in Figure 1). The control unit 20 is then further intended to activate this third light source when this photodiode measures optical radiation less than or equal to a predefined threshold of optical radiation, that is to say when the external brightness becomes low.
Dans ce cas, cette troisième source de lumière serait de couleur rouge et remplirait une fonction de feu de position.  In this case, this third light source would be red in color and fulfill a position light function.
Dans un autre exemple, le dispositif 10 comporte en outre une quatrième source de lumière et un détecteur de brouillard et de bruine (non représentés sur la figure 1). L’unité de contrôle 20 est alors en outre destinée à activer cette quatrième source de lumière lorsque ce détecteur mesure une hygrométrie supérieure ou égale à un seuil prédéfini d’hygrométrie, c’est-à-dire lorsque l’humidité de l’air devient élevée.  In another example, the device 10 further comprises a fourth light source and a fog and mist detector (not shown in Figure 1). The control unit 20 is then also intended to activate this fourth light source when the detector measures a humidity greater than or equal to a predefined humidity threshold, that is to say when the humidity of the air becomes high.
Dans ce cas, cete quatrième source de lumière serait de couleur rouge et remplirait une fonction de feu de brouillard. A cet effet, cette quatrième source de lumière serait plus puissante que les autres qui, de préférence sont configurées pour être visibles par un observateur à 50 mètres de jour et 150 mètres de nuit. De préférence, le premier seuil prédéfini de décélération est compris entre 0,2 et 0,3 m/s2, et le deuxième seuil prédéfini de décélération est de l’ordre de 20 m/s2. In this case, this fourth light source would be red in color and fulfill a fogging function. For this purpose, this fourth light source would be more powerful than the others, which are preferably configured to be visible by an observer at 50 meters of day and 150 meters of night. Preferably, the first predefined deceleration threshold is between 0.2 and 0.3 m / s 2 , and the second predefined deceleration threshold is of the order of 20 m / s 2 .
Dans le cas où le dispositif 10 est fixé à un casque, ledit dispositif comporte en outre une surface concave souple (non représentée sur la figure 1) destinée à être en contact avec ledit casque, et une surface convexe (non représentée sur la figure 1) à travers laquelle sont disposées la ou les source(s) de lumière 50.  In the case where the device 10 is attached to a helmet, said device further comprises a flexible concave surface (not shown in Figure 1) intended to be in contact with said helmet, and a convex surface (not shown in Figure 1 ) through which the source (s) of light 50 are arranged.
De préférence, le dispositif 10 est fixé de manière amovible à l’accessoire porté par le conducteur de véhicule terrestre.  Preferably, the device 10 is removably attached to the accessory carried by the land vehicle driver.
Dans un exemple, l’élément souple est réalisé en caoutchouc ou en tout autre matériau élastique naturel et/ou synthétique.  In one example, the flexible element is made of rubber or any other natural and / or synthetic elastic material.
De préférence, les batteries d’accumulateurs électrochimiques Bl et B2 sont rechargeables, via un port USB et, dans un exemple, lesdites batteries sont de type lithium- ion polymère.  Preferably, the electrochemical storage batteries B1 and B2 are rechargeable, via a USB port and, in one example, said batteries are lithium-ion polymer type.
De préférence encore, le dispositif 10 comporte un indicateur de son état de charge (non représenté sur la figure 1) qui est  More preferably, the device 10 includes an indicator of its state of charge (not shown in FIG.
soit binaire si ledit état de charge est défini comme étant suffisant ou insuffisant, soit gradué si ledit état de charge est défini comme étant un taux de charge absolu. or binary if said state of charge is defined as sufficient or insufficient, or graduated if said state of charge is defined as being an absolute charge rate.
La présente invention peut également s’appliquer aux bicyclettes, notamment dans le cas où l’on souhaite rendre le cycliste plus visible grâce à un système de feu de freinage qui s’active à la décélération du cycliste. The present invention can also be applied to bicycles, especially in the case where it is desired to make the cyclist more visible thanks to a brake light system which is activated at the deceleration of the cyclist.
Ce dispositif à un vrai intérêt sécuritaire puisqu’il rend le cycliste plus visible par les autres usagers. Il peut fonctionner de façon autonome et peut également être en communication, de préférence par voie non fïlaire, avec une application informatique offrant des options comme l’alerte secours assistance et un mode de détection d’accidents.  This device has a real safety interest since it makes the cyclist more visible to other users. It can operate autonomously and can also be in communication, preferably non-wired, with a computer application offering options such as emergency assistance assistance and an accident detection mode.
Dans le cas particulier de bicyclettes, différentes options et fonctionnalités, implémentées dans des modules informatiques correspondants développés par le demandeur de la présente demande de brevet, sont susceptibles d’être mises en œuvre.  In the particular case of bicycles, various options and functionalities, implemented in corresponding computer modules developed by the applicant of this patent application, are likely to be implemented.
Dans ce cas, l’invention concerne un dispositif de signalisation 10 destiné à être porté par un conducteur de véhicule terrestre ou destiné à être adapté sur un tel véhicule, ce véhicule étant de préférence un véhicule à deux roues, qui peut comprendre tout ou partie des caractéristiques présentées plus haut.  In this case, the invention relates to a signaling device 10 intended to be carried by a land vehicle driver or intended to be adapted to such a vehicle, this vehicle preferably being a two-wheeled vehicle, which may comprise all or part of characteristics presented above.
Ainsi, les fonctionnalités suivantes peuvent être mise en œuvre : - activation de façon autonome des feux de freinage par la décélération du cycliste (comme décrit ci-dessus) ; Thus, the following features can be implemented: - autonomous activation of the brake lights by the deceleration of the cyclist (as described above);
- possibilité de mettre en œuvre différents modes d’éclairage (feu de position, feu de freinage, feu en mode waming) ;  - possibility of implementing different lighting modes (position lamp, brake light, fire in waming mode);
- utilisation et activation de feux clignotants.  - use and activation of flashing lights.
Différents modes de déclenchement sont possibles pour l’activation des clignotants, soit :  Different trigger modes are possible for activating turn signals, ie:
■ Déclenchement via le système de géolocalisation, par exemple de type GPS ■ Triggering via the geolocation system, for example of the GPS type
Le cycliste entre au préalable son trajet dans une application permettant de suivre l’itinéraire correspondant.  The cyclist first enters his journey in an application to follow the corresponding route.
Les clignotants sont alors déclenchés en fonction du déplacement du cycliste sur l’itinéraire proposé, et en fonction de la géolocalisation du cycliste au cours de ce déplacement, en particulier à l’approche d’un changement de direction détecté par l’application. Dans un tel cas, un signal d’activation de clignotant est envoyé au dispositif de signalisation, et le clignotant correspondant est activé selon les instructions requises pour le trajet à effectuer.  The turn signals are then triggered according to the movement of the cyclist on the proposed route, and depending on the geolocation of the cyclist during this movement, especially when approaching a change of direction detected by the application. In such a case, a flashing activation signal is sent to the signaling device, and the corresponding flashing light is activated according to the instructions required for the journey to be made.
■ Déclenchement via une application ■ Triggering via an application
Le cycliste peut activer les clignotants via l’application en fonctionnement sur un dispositif informatique portable, tel qu’un téléphone portable, dans un menu de l’application spécifique à cette fonction. L’application est lancée par le cycliste, le dispositif informatique portable étant disponible de préférence sur le guidon via par exemple un support adapté à ce dispositif. Le cycliste déclenche alors de façon manuelle le clignotant droit ou gauche selon son itinéraire.  The cyclist can activate the turn signals via the application in operation on a portable computing device, such as a mobile phone, in a menu of the application specific to this function. The application is launched by the cyclist, the portable computing device being preferably available on the handlebars via, for example, a support adapted to this device. The cyclist then manually triggers the right or left turn signal according to his route.
■ Déclenchement via une télécommande ■ Triggering via a remote control
Une telle commande peut être fixée au guidon, par attache ou par des moyens adhésifs ou tout autre moyen de fixation, et permet au cycliste de déclencher via un moyen de commande, qui peut être un bouton tel qu’un bouton pressoir, le clignotant droit ou gauche. Cette télécommande est elle-même en communication avec le dispositif de signalisation, de préférence par voie non filaire, par exemple via un mode de communication de type Bluetooth.  Such a control can be fixed to the handlebar, by attachment or by adhesive means or any other means of attachment, and allows the cyclist to trigger via a control means, which may be a button such as a press button, the right turn signal or left. This remote control is itself in communication with the signaling device, preferably by non-wired means, for example via a Bluetooth type of communication mode.
Différents modes de fixation du dispositif de signalisation sont possibles par exemple via un système de clip, ou tout autre moyen de fixation tel une fixation par adhésif, par l’intermédiaire d’une bague, etc. Ce support peut être fixé au casque du cycliste ou sur un élément du véhicule à deux roues, par exemple sur le porte bagage arrière du véhicule via le système de fixation évoqué ci-dessus. Different ways of fixing the signaling device are possible for example via a clip system, or any other fastening means such as an adhesive attachment, via a ring, etc. This support can be attached to the cyclist's helmet or on a component of the two-wheeled vehicle, for example on the rear luggage rack of the vehicle via the fixing system mentioned above.
Le dispositif peut être connecté à une application informatique dédiée, tel qu’indiqué plus haut, les différentes fonctionnalités mises en œuvre sur cette application étant notamment les suivantes :  The device can be connected to a dedicated computer application, as indicated above, the various functionalities implemented on this application being in particular the following:
o La géo localisation o Geolocation
■ géolocalisation du cycliste par système de type GPS ; ■ geolocation of the cyclist by GPS system;
■ calcul et proposition d’itinéraires via le système de type GPS relié à différents opérateurs et éditeurs d’application ; ■ calculation and proposal of itineraries via the GPS type system connected to different operators and application editors;
■ calcul d’un itinéraire en fonction des préférences du cycliste, par exemple : ■ calculating a route according to the preferences of the cyclist, for example:
¨ ¨ ¨ le cycliste choisit un itinéraire qui emprunte uniquement les chemins de randonnées de type GR (« Grande Randonnée ») ou autres types ; ¨ ¨ ¨ the cyclist chooses a route that uses only the GR ("Grande Randonnée") hiking trails or other types;
¨ ¨ ¨ le cycliste choisit un itinéraire en fonction de paramètres routiers définis (itinéraires avec ou sans dénivelés, itinéraires offrants des pistes cyclables, etc...) ; ¨ ¨ ¨ the cyclist chooses a route according to defined road parameters (itineraries with or without unevenness, itineraries offering cycle paths, etc.);
■ partage de trajets avec d’autres utilisateurs : ■ sharing trips with other users:
¨> fonction «partage» : mode d’accès sur différents dispositifs informatiques tels que des téléphones portables, pour partager les trajets avec d’autres utilisateurs ; ce mode offre la possibilité de géolocaliser un proche à tout moment ; à titre d’exemple un parent pourra localiser son enfant durant ses trajets en vélo ; ¨ >"sharing" function: access mode on different computing devices such as mobile phones, to share the paths with other users; this mode offers the possibility of geolocating a loved one at any time; for example, a parent will be able to locate his child while cycling;
¨> partage de trajets sur des réseaux sociaux ¨ > sharing trips on social networks
o Détection de chute ou d’accident comme prévu ci-dessus, à savoir entre autres : le système intègre un algorithme permettant d’identifier la chute du cycliste. o Fall or crash detection as described above, including: the system incorporates an algorithm to identify the fall of the cyclist.
■ En cas de chute, l’application envoie un message « d’incident » à un centre de secours qui sera en mesure de vérifier (suite à un appel téléphonique par exemple) auprès du cycliste si l’incident est avéré. En cas de non réponse du cycliste, les secours pourront être déclenchés automatiquement, dans un temps très réduit, de préférence en moins de 5 minutes, par le centre d’appel. ■ In the event of a fall, the application sends an "incident" message to a rescue center that will be able to check (following a phone call, for example) with the cyclist if the incident is proven. If the cyclist does not answer, the emergency services can be triggered automatically, in a very short time, preferably in less than 5 minutes, by the call center.
■ Le cycliste peut également déclencher les secours de façon autonome grâce à un bouton d’alerte présent dans l’application. ■ Un bouton d’alerte pour les proches est également prévu dans l’application, pour que le cycliste puisse alerter ses proches, par exemple par SMS, d’un incident. ■ The cyclist can also activate the rescue autonomously thanks to an alert button present in the application. ■ A warning button for relatives is also provided in the application, so that the cyclist can alert his relatives, for example by SMS, an incident.
■ Pour les enfants qui n’ont pas encore de téléphone mobile, un système d’alerte via une télécommande leur permet d’avertir leurs parents en cas d’incident. Cet accessoire supplémentaire est similaire au, ou intégrer au, dispositif de télécommande des clignotants à fixer sur le guidon de la bicyclette décrite ci- dessus. ■ For children who do not have a mobile phone yet, an alarm system via a remote control allows them to notify their parents in the event of an incident. This additional accessory is similar to, or integrated into, the remote control device of the turn signals to be fixed on the handlebar of the bicycle described above.
