Title
(EN) HYBRID ELECTRIC VEHICLE, DRIVE CONTROL METHOD AND DEVICE OF THE SAME
(FR) VÉHICULE ÉLECTRIQUE HYBRIDE, PROCÉDÉ ET DISPOSITIF DE COMMANDE D'ENTRAÎNEMENT ASSOCIÉS
Abstract
(EN)
A drive control method, a drive control device of a hybrid electric vehicle and a hybrid electric vehicle are provided. The drive control method includes: obtaining a current gear position of the hybrid electric vehicle, a current electric charge level of a power battery and a slope of a road on which the hybrid electric vehicle is driving; obtaining a current speed of the hybrid electric vehicle if the current gear position of the hybrid vehicle, the current electric charge level of the power battery, and the slope of the road on which the hybrid electric vehicle is driving meet a preset requirement; and causing the hybrid electric vehicle to enter a small load stop function if the current speed is greater than or equal to a first speed threshold, and less than a second speed threshold.
(FR)
L'invention concerne un procédé de commande d'entraînement, un dispositif de commande d'entraînement d'un véhicule électrique hybride et un véhicule électrique hybride. Le procédé de commande d'entraînement comprend les étapes consistant à: obtenir une position de vitesse actuelle du véhicule électrique hybride, un niveau de charge de courant électrique d'une batterie d'alimentation et une inclinaison d'une route sur laquelle le véhicule électrique hybride se déplace; obtenir une vitesse actuelle du véhicule électrique hybride si la position de vitesse actuelle du véhicule hybride, le niveau de charge de courant électrique de la batterie d'alimentation et l'inclinaison de la route sur laquelle le véhicule électrique hybride se déplace remplissent une condition prédéfinie; et amener le véhicule électrique hybride à assurer une fonction d'arrêt à faible charge si la vitesse actuelle est supérieure ou égale à une première vitesse seuil et inférieure à une seconde vitesse seuil.
