Abstract

La présente invention concerne un véhicule comprenant un moteur principal d'entraînement (20) couplé à une paire de roues (10, 12) porteuses et motrices et un système d'assistance comprenant un moteur hydraulique (62) couplé à certaines des roues porteuses (14, 16), une machine hydraulique formant pompe (60) reliée au moteur hydraulique (62) et des capteurs (82) de patinage et vitesse des roues, un module de commande (80) qui assure la mise en service de l'assistance sur la base des signaux issus des capteurs (82), le module de commande (80) exploitant un logiciel (90) de limitation de puissance du moteur principal (20) et des moyens de pilotage de ce logiciel ajustant la puissance du moteur en tenant compte de l'engagement ou non du système d'assistance, et qui ajuste la pression maximale hydraulique pour éviter une surpression hydraulique.
