Abstract
(EN)
A dual-motor wire-controlled composite steering system and a control method therefor, wherein the dual-motor wire-controlled composite steering system comprises a steering wheel (1), a steering column assembly, a road sensing assembly, a dual-motor steering actuator, and a steering control unit. Steering control of the system is completed by means of an adaptive control method, and the present system may achieve the integration of steering performance such as relatively large steering torques, lower energy consumption, faster response speeds and so on. The present control method automatically adjusts steering control parameters according to an actual driving situation, which may better counter uncertainty in a driving environment and ensure steering accuracy and vehicle safety.

L'invention concerne un système de direction composite à double moteur commandé par câble et son procédé de commande, le système de direction composite à double moteur commandé par câble comprenant un volant de direction (1), un ensemble colonne de direction, un ensemble de détection de route, un actionneur de direction à double moteur et une unité de commande de direction. La commande de direction du système est réalisée au moyen d'un procédé de commande adaptatif, et le présent système peut parvenir à l'intégration de performance de direction telle que des couples de direction relativement importants, une consommation d'énergie plus faible, des vitesses de réponse plus rapides, etc. Le présent procédé de commande ajuste automatiquement des paramètres de commande de direction en fonction d'une situation de conduite réelle, ce qui peut mieux contrer une incertitude dans un environnement de conduite et assurer une précision de direction et une sécurité de véhicule.
