Abstract: front page image
(EN)A method to provide a selective torque assist to the primary motor in an electric vehicle/Hybrid vehicle is disclosed. The method comprises of embedding torque assist motors on the two output shafts of the primary motor differential. The torque assist motors can be turned ON to provide a short term torque boost to the primary motor differential particularly at zero or very low speed. The Torque assist motors may have multiple windings to provide different torque boost.
(FR)L'invention concerne un procédé pour fournir une assistance de couple sélective dans un moteur primaire d'un véhicule électrique / véhicule hybride. Le procédé consiste à intégrer des moteurs à assistance de couple aux deux arbres de sortie du différentiel du moteur primaire. Les moteurs à assistance de couple peuvent être enclenchés pour fournir un bref effort de couple au différentiel du moteur primaire, notamment à vitesse faible ou nulle. Le moteurs à assistance de couple peuvent avoir des enroulements multiples pour fournir des efforts de couple différents.
