Abstract
(EN)
Disclosed are a self-adaptive vehicle road-curve auxiliary control method and apparatus, and a computer device and a storage medium. The method comprises: step S10, according to a signal from a sensor of a vehicle, identifying the type of current road curve, and obtaining, corresponding to the type of road curve, a lateral impact strength of the current vehicle according to a lateral acceleration; step S11, carrying out calculation according to the lateral impact strength to obtain an expected longitudinal acceleration; step S12, according to the expected longitudinal acceleration and a current actual longitudinal acceleration, determining an activation type for currently carrying out road-curve auxiliary control; and step S13, according to the activation type, cooperatively controlling an engine torque or/and an ESC braking intensity, so as to realize expected longitudinal control over the vehicle in the road curve. By means of the method, longitudinal auxiliary control over a vehicle can be carried out on the premise of unawareness of the driver, thereby improving the dynamic performance of the vehicle during turning.

L'invention concerne un procédé et un appareil de commande auxiliaire auto-adaptative d'un véhicule aux virages de la route, et un dispositif informatique et un support de stockage. Le procédé comprend les étapes suivantes : S10, en fonction d'un signal provenant d'un capteur d'un véhicule, identification du type de virage actuel de la route et obtention, en correspondance au type de virage de la route, d'une force d'impact latérale du véhicule actuel en fonction d'une accélération latérale ; S11, réalisation d'un calcul en fonction de la force d'impact latérale pour obtenir une accélération longitudinale attendue ; S12, en fonction de l'accélération longitudinale attendue et d'une accélération longitudinale réelle actuelle, détermination d'un type d'activation pour effectuer actuellement une commande auxiliaire de virage de la route ; et S13, en fonction du type d'activation, commande coopérative d'un couple moteur et/ou d'une intensité de freinage d'ESC, de façon à réaliser une commande longitudinale attendue sur le véhicule dans le virage de la route. Le procédé permet de réaliser une commande auxiliaire longitudinale sur un véhicule en supposant l'absence de conscience du conducteur, ce qui permet d'améliorer les performances dynamiques du véhicule pendant le virage.
