Abstract

L'invention concerne un procédé de conduite de véhicule électrique à précession assistée, se rapportant au domaine des véhicules électriques, et comprenant les étapes suivantes : étape A : commander au moins une paire d'éléments gyroscopiques de la moitié avant et/ou de la moitié arrière d'un véhicule électrique pour qu'ils tournent autour de leurs axes ; étape B : modifier l'angle des axes des éléments gyroscopiques avec le châssis du véhicule électrique ou verrouiller ledit angle. L'étape A et l'étape B peuvent être mises en œuvre simultanément ou séparément. Le présent procédé est un procédé de conduite de véhicule électrique à précession assistée destiné à réduire la perte d'énergie cinétique du véhicule lors du passage sur des nids de poule ou des obstacles, améliorer la capacité de franchissement et réduire les secousses afin d'améliorer l'expérience de conduite du passager.
