Abstract
(EN) A predictive EGR control method, a terminal device, and a storage medium. The method comprises: determining, according to data of an electronic horizon line in front of a vehicle, whether there is a deceleration road section in front of the vehicle, if yes, calculating an engine output torque to be reduced during traveling from a current position of the vehicle to a starting position of the deceleration road section and/or an engine output torque to be increased during traveling from the starting position of the deceleration road section to an end position of the deceleration road section, thereby adjusting an EGR ratio of the vehicle at the current position thereof according to the engine output torque to be reduced and/or adjusting the EGR ratio of the vehicle at the starting position of the deceleration road section according to the engine output torque to be increased. According to the method, front terrain information provided by the electronic horizon line is fully utilized, and before entering an environment where the speed can be reduced, an EGR valve is turned on in advance, and the EGR ratio is increased, so as to reduce discharge of noxious gas.
(FR) L'invention concerne un procédé de commande EGR prédictif, un dispositif terminal et un support de stockage. Le procédé comprend les étapes consistant à : déterminer, en fonction des données d'une ligne d'horizon électronique devant un véhicule, s'il y a une section de route de décélération devant le véhicule, si oui, calculer un couple de sortie moteur à réduire pendant le déplacement d'une position actuelle du véhicule à une position de départ de la section de route de décélération et/ou un couple de sortie moteur à augmenter pendant le déplacement depuis la position de départ de la section de route de décélération jusqu'à une position de fin de la section de route de décélération, ce qui permet de régler un rapport EGR du véhicule à sa position actuelle en fonction du couple de sortie moteur à réduire et/ou de régler le rapport EGR du véhicule à la position de départ de la section de route de décélération en fonction du couple de sortie moteur à augmenter. Selon le procédé, des informations de terrain avant fournies par la ligne d'horizon électronique sont complètement utilisées et, avant d'entrer dans un environnement où la vitesse peut être réduite, une soupape EGR est activée à l'avance, et le rapport EGR est augmenté, de façon à réduire la décharge de gaz nocif.
(ZH) 一种预测性EGR控制方法、终端设备及存储介质,该方法中包括:根据车辆前方的电子地平线数据判断车辆前方是否存在减速路段,如果存在,则计算从车辆当前位置行驶至减速路段的起始位置需要降低的发动机输出扭矩和/或从减速路段的起始位置行驶至减速路段的结束位置需要增加的发动机输出扭矩,进而根据需要降低的发动机输出扭矩在车辆当前位置处调整车辆的EGR比率和/或根据需要增加的发动机输出扭矩在减速路段的起始位置处调整车辆的EGR比率。该方法充分利用电子地平线提供的前方地形信息,在进入可减速环境之前,提前开启EGR阀并增加EGR比率,以减少有害气体排放。
