Title
(EN) SYSTEM FOR STEERING A HYBRID VEHICLE COMPRISING FOUR DRIVING WHEELS
(FR) DISPOSITIF DE PILOTAGE D'UN VEHICULE HYBRIDE A QUATRE ROUES MOTRICES
Abstract
(EN)
The invention relates to a system (10) for steering a vehicle comprising four driving wheels and two trains, a front train (20) and a rear train (18), each train being driven by an actuator. The system especially comprises a means for converting the torques (Cav, Car) applied to the trains (18, 20) into set torque values (Cm, Cel, Xemb) for controlling the actuators, and is characterised in that it comprises a regulation means for regulating the set torque values on the basis of a dynamic behaviour model of the vehicle, created by a means for modelling the dynamic behaviour of the vehicle, said regulation means controlling a means for limiting the mechanical shock effects and/or a means for ensuring a stable behaviour of the vehicle during a change in the driving situation.
(FR)
L'invention concerne un dispositif de pilotage (10) d'un véhicule à quatre roues motrices comportant deux trains, un train avant (20) et un train arrière (18) et dont chaque train est entraîné par un actionneur, le dispositif comporte notamment un moyen pour convertir les couples (Cav, Car) appliqués aux trains (18, 20) en consignes de couple (Cm, CeI, Xemb) pour commander les actionneurs caractérisé en ce qu'il comporte un moyen de régulation des consignes de couple sur la base d'un modèle de comportement dynamique du véhicule exécuté par un moyen de modélisation du comportement dynamique du véhicule, le dit moyen de régulation commandant un moyen pour limiter les effets de choc mécanique et/ou un moyen pour assurer un comportement stable du véhicule lors d'un changement de situation de conduite.
