Claims (9)
- REVENDICATIONS1 Procédé de sécurisation en cas d'accident d'un véhicule hybride comportant une machine électrique de traction pilotée par un onduleur (4) relié à une batterie de stockage (6) équipée d'un contacteur de puissance (18), cette batterie pouvant alimenter le réseau de bord très basse tension du véhicule (36) par un convertisseur de tension DC/DC (10) dans un mode d'abaissement de la tension, les composants de puissance comportant des condensateurs de filtrage du courant (44, 46), le véhicule étant équipé de capteurs de choc(30) qui déclenchent des moyens de protection des passagers, caractérisé en ce qu'après la détection d'un choc qui entraîne l'ouverture du contacteur de puissance (18) de la batterie de stockage (6), il commande l'alimentation du réseau de bord (36) par le convertisseur DC/DC (10) afin de vider les condensateurs des éléments de puissance (44, 46) dans ce réseau.
- 2- Système électrique de traction pour un véhicule hybride comportant une machine électrique de traction pilotée par un onduleur (4) relié à une batterie de stockage (6) équipée d'un contacteur de puissance (18), cette batterie pouvant alimenter le réseau de bord très basse tension du véhicule (36) par un convertisseur de tension DC/DC (10) dans un mode d'abaissement de la tension, les composants de puissance comportant des condensateurs de filtrage du courant (44, 46), le véhicule étant équipé de détecteurs de chocs (30) qui déclenchent des moyens de protection des passagers, caractérisé en ce qu'il comporte des moyens mettant en oeuvre un procédé de sécurisation selon la revendication 1.
- 3 - Système électrique selon la revendication 2, caractérisé en ce qu'il comporte un réseau filaire direct (32) envoyant un signal analogique venant des capteurs de choc (30) au convertisseur DC/DC (10), pour commander son alimentation du réseau de bord (36).
- 4- Système électrique selon la revendication 3, caractérisé en ce que le réseau filaire direct (32) envoie aussi un signal analogique à l'onduleur de la 301 9 1 1 1 9 machine électrique (4), et à des moyens de contrôle (26) de la batterie de stockage (6).
- 5 - Système électrique selon l'une quelconque des revendications 2 à 4, caractérisé en ce que l'onduleur de la machine électrique (4) comporte un 5 condensateur de filtrage (44) du courant d'alimentation, qui ne présente pas entre ses pôles de contacteur (40) équipé d'une résistance de dissipation disposée en série (42).
- 6- Système électrique selon l'une quelconque des revendications 2 à 5, caractérisé en ce que la batterie de stockage (6) comporte un unique 10 contacteur de puissance (18) reliant les cellules de stockage d'énergie (16), à l'onduleur de la machine électrique (4) et au convertisseur DC/DC (10).
- 7 - Véhicule hybride électrique disposant d'un système électrique pour la traction, caractérisé en ce que ce système est réalisé selon l'une quelconque des revendications 2 à 6. 15
- 8 - Véhicule hybride électrique selon la revendication 7, caractérisé en ce qu'il comporte un moteur thermique entraînant par une transmission les roues avant, la machine électrique de traction étant liée mécaniquement à ce moteur,
- 9 - Véhicule hybride électrique selon la revendication 7 ou 8, caractérisé 20 en ce qu'il comporte une autre machine électrique entraînant les roues arrière.
