Description

Système électronique de protection pour véhicule à propulsion électriqueElectronic protection system for electrically propelled vehicle

La présente invention concerne un système électronique.The present invention relates to an electronic system.

De nombreux véhicules sont équipés d’un moteur électrique alimenté par une batterie. Certaines batteries peuvent être enlevées du véhicule électrique par exemple pour être rechargées. Auquel cas, le véhicule électrique se retrouve sans batterie. Or, certaines fonctions autres que l’entraînement du moteur électrique telles que la fonction antivol du véhicule peuvent être assurées par l’alimentation de la batterie du véhicule électrique. Ainsi, lorsque la batterie est enlevée, ces fonctions peuvent se retrouver momentanément désactivées.Many vehicles are equipped with an electric motor powered by a battery. Some batteries can be removed from the electric vehicle for example to be recharged. In which case, the electric vehicle is left without a battery. However, certain functions other than driving the electric motor, such as the anti-theft function of the vehicle, can be ensured by the power supply from the battery of the electric vehicle. Thus, when the battery is removed, these functions may be temporarily disabled.

La présente demande cherche ainsi à améliorer cette situation.The present application thus seeks to improve this situation.

Présentation de l’inventionPresentation of the invention

Un objectif de la présente demande est donc de proposer un système électronique permettant d’alimenter un système de protection antivol d’un véhicule électrique même lorsqu’une batterie de traction du véhicule est désaccouplée du véhicule électrique.An objective of the present application is therefore to propose an electronic system making it possible to supply an anti-theft protection system of an electric vehicle even when a traction battery of the vehicle is uncoupled from the electric vehicle.

A cet égard, l’invention propose un système électronique comprenant un convertisseur alternatif/continu passif connecté d’une part à un système de protection antivol et d’autre part à un moteur électrique, le moteur électrique étant relié à une roue d’un véhicule à propulsion électrique,
le système électronique étant caractérisé en ce que lorsque la roue du véhicule électrique est mise en rotation par une source externe au moteur électrique, ce dernier tourne et génère une tension alternative convertie par le convertisseur alternatif/continu passif en une tension de sortie alimentant le système de protection antivol.In this respect, the invention proposes an electronic system comprising a passive AC/DC converter connected on the one hand to an anti-theft protection system and on the other hand to an electric motor, the electric motor being connected to a wheel of a electric powered vehicle,
the electronic system being characterized in that when the wheel of the electric vehicle is rotated by a source external to the electric motor, the latter rotates and generates an alternating voltage converted by the passive alternating/direct converter into an output voltage supplying the system anti-theft protection.

Le système électronique permet ainsi de protéger un véhicule à propulsion électrique contre un vol par une utilisation astucieuse du moteur électrique en mode générateur alimentant un ensemble autonome de conversion d’énergie et de déclenchement d’un système de protection antivol.The electronic system thus makes it possible to protect an electric-powered vehicle against theft by clever use of the electric motor in generator mode supplying an autonomous assembly for energy conversion and triggering of an anti-theft protection system.

Optionnellement, le système de protection antivol comprend un condensateur. Cela permet une intégration simple au système de protection antivol tout en permettant de restituer l’énergie accumulée de manière immédiate.Optionally, the anti-theft protection system includes a capacitor. This allows easy integration into the anti-theft protection system while allowing the stored energy to be returned immediately.

Optionnellement, le système de protection antivol se déclenche lorsqu’une tension à ses bornes atteint un seuil prédéterminé. Cela permet de déclencher le système de protection antivol dès qu’une quantité suffisante d’énergie nécessaire à son déclenchement a été accumulée.Optionally, the anti-theft protection system is triggered when the voltage at its terminals reaches a predetermined threshold. This makes it possible to trigger the anti-theft protection system as soon as a sufficient quantity of energy necessary for its triggering has been accumulated.

Optionnellement, le système de protection antivol est désactivé lorsqu’un signal de clef du véhicule électrique est détecté. Cela permet d’éviter à un propriétaire du véhicule à propulsion électrique de déclencher le système de protection antivol.Optionally, the anti-theft protection system is deactivated when an electric vehicle key signal is detected. This prevents an owner of the electrically driven vehicle from triggering the anti-theft protection system.

Optionnellement, le déclenchement du système de protection antivol peut comprendre une commande de l’une au moins des actions suivantes :
- un allumage d’un feu du véhicule électrique, ou
- un signal sonore émis par le véhicule électrique, ou
- un message ou un appel sur un réseau sans fil.Optionally, the triggering of the anti-theft protection system may include a command for at least one of the following actions:
- ignition of a fire in the electric vehicle, or
- an audible signal emitted by the electric vehicle, or
- a message or a call on a wireless network.

Cela permet d’alerter sur le fait que le véhicule à propulsion électrique est en train d’être volé.This alerts that the electrically powered vehicle is being stolen.

Optionnellement, le système électronique comprend également une batterie de traction et une unité de commande du moteur, configurée pour commander une traction du véhicule par rotation de la roue, et le cas échéant une unité de freinage récupératif lorsque la batterie de traction est accouplée à ladite unité de commande, ledit convertisseur alternatif/continu passif étant configuré pour fonctionner même lorsque la batterie de traction est désaccouplée de ladite unité de commande. Cela permet de déclencher le système de protection antivol même lorsque la batterie de traction est désaccouplée du véhicule.Optionally, the electronic system also comprises a traction battery and a motor control unit, configured to control traction of the vehicle by rotation of the wheel, and if necessary a regenerative braking unit when the traction battery is coupled to said control unit, said passive AC/DC converter being configured to operate even when the traction battery is uncoupled from said control unit. This allows the anti-theft protection system to be triggered even when the traction battery is uncoupled from the vehicle.

Optionnellement, le convertisseur alternatif/continu passif comprend un redresseur double alternance. Le redresseur double alternance permet de redresser une tension alternative de manière efficace de façon passive.Optionally, the passive AC/DC converter comprises a full-wave rectifier. The full-wave rectifier makes it possible to rectify an alternating voltage effectively in a passive way.

Optionnellement, le convertisseur alternatif/continu passif comprend une diode Zener. La diode Zener permet d’avoir accès à une tension sensiblement continue à ses bornes de manière passive.Optionally, the passive AC/DC converter comprises a Zener diode. The Zener diode provides passive access to a substantially DC voltage across its terminals.

L’invention porte par ailleurs sur un véhicule à propulsion électrique, par exemple un scooter à propulsion électrique, embarquant un système électronique tel que présenté selon l’une des options décrites ci-dessus.The invention also relates to an electrically powered vehicle, for example an electrically powered scooter, incorporating an electronic system as presented according to one of the options described above.

D’autres caractéristiques, détails et avantages apparaîtront à la lecture de la description détaillée ci-après, et à l’analyse des dessins annexés, sur lesquels :Other characteristics, details and advantages will appear on reading the detailed description below, and on analyzing the appended drawings, in which:
