Title (EN) METHOD, DEVICE, AND SYSTEM FOR POWER DISTRIBUTION CONTROL OF VEHICLE
(FR) PROCÉDÉ, DISPOSITIF ET SYSTÈME DE COMMANDE DE DISTRIBUTION D'ÉNERGIE ÉLECTRIQUE D'UN VÉHICULE

Abstract:
(EN) A method, device, and system for power distribution control of a vehicle. The method comprises: acquiring an image of the road surface on which a vehicle is currently traveling, recognizing, on the basis of the image of the road surface, the type of the road surface on which the vehicle is currently traveling; turning on a corresponding terrain mode in an all-terrain adaptation mode on the basis of the current type of road surface; determining a power distribution strategy corresponding to the current terrain mode on the basis of correlations between terrain modes and preset power distribution strategies; switching a central differential of the vehicle to a corresponding lock mode on the basis of the current power distribution strategy and, in the lock mode, distributing torque for the front and rear axles of the vehicle on the basis of a torque distribution curve corresponding to the current power distribution strategy; this favors the front and rear axles of a four-wheel drive vehicle to be provided with adequate torques on different road surfaces.
(FR) L'invention concerne un procédé, un dispositif et un système de commande de distribution d'énergie électrique d'un véhicule. Le procédé consiste : à acquérir une image d'une surface de route empruntée au moment présent par un véhicule, à reconnaître, en fonction de l'image de surface de route, le type de la surface de route empruntée au moment présent par le véhicule ; à démarrer un mode terrain correspondant dans un mode d'adaptation tout terrain en fonction du type de surface de route actuel ; à déterminer une stratégie de distribution d'énergie électrique correspondant au mode terrain actuel en fonction de corrélations entre des modes terrain et des stratégies de distribution d'énergie électrique prédéfinies ; à commuter un différentiel central du véhicule vers un mode de verrouillage correspondant en fonction de la stratégie de distribution d'énergie électrique actuelle et, dans le mode de verrouillage, à distribuer le couple pour les essieux avant et arrière du véhicule en fonction d'une courbe de distribution de couple correspondant à la stratégie de distribution d'énergie électrique actuelle ; ceci permet aux essieux avant et arrière d'un véhicule à quatre roues motrices d'être fournis avec des couples adéquats sur des surfaces de route différentes.
(ZH) 一种车辆的动力分配控制方法、装置及系统。所述方法包括:获取车辆当前行驶的路面图像,根据所述路面图像识别车辆当前行驶的路面类型;根据当前的路面类型启动全地形适应模式下对应的地形模式;并根据地形模式与预设的动力分配策略的对应关系,确定与当前地形模式对应的动力分配策略;根据当前动力分配策略将车辆的中央差速器切换至对应的锁止模式,在所述锁止模式下,根据当前动力分配策略对应的扭矩分配曲线为车辆的前后轴分配扭矩;有利于四驱车辆在不同路面前后轴均能得到适当的扭矩。
