Abstract:
(EN) Disclosed is a driving support system of vehicle wherein a vehicle is made to follow up a target guideway without causing unstable behavior of the vehicle. A vehicle (10) has a VGRS actuator (200) as a means for varying the steering angle, and an EPS actuator (400) as a means for assisting torque. When the vehicle (10) follows up a target guideway, an LKA target assist torque (TLK) is outputted from the EPS actuator (400) based on a target lateral acceleration (GYTG). On the other hand, a steering wheel (11) is steered excessively by an LKA correction target angle θLK by means of the VGRS actuator (200) in order to suppress unintended steering of the steering wheel by a driver caused by such an assist torque. Since the relation between the steering angle and the rotation angle of a lower steering shaft (13) is not affected, the vehicle can follow up the target guideway without reducing robustness of the vehicle for steering of the driver.
(FR) L'invention concerne un système d'assistance à la conduite de véhicule, un véhicule étant amené à suivre une glissière cible sans provoquer un comportement instable du véhicule. Un véhicule (10) comporte un actionneur de VGRS (200) en tant que moyens pour modifier l'angle de braquage, et un actionneur d'EPS (400) en tant que moyens pour assister au couple. Lorsque le véhicule (10) suit une glissière cible, un couple d'assistance cible de LKA (TLK) est délivré par l'actionneur d'EPS (400) sur la base d'une accélération latérale cible (GYTG). D'autre part, un volant (11) est braqué excessivement d'un angle cible de correction de LKA θLK au moyen de l'actionneur de VGRS (200) afin de supprimer un braquage involontaire du volant par un conducteur provoqué par un tel couple d'assistance. Etant donné que la relation entre l'angle de braquage et l'angle de rotation d'un arbre de direction inférieur (13) n'est pas affectée, le véhicule peut suivre la glissière cible sans réduire la robustesse du véhicule pour le braquage par le conducteur.
(JA) 車両挙動の不安定化を招くことなく車両を目標走行路に追従させる。 車両10は、舵角可変手段としてのVGRSアクチュエータ200と、操舵トルク補助手段としてのEPSアクチュエータ400とを備える。目標走行路への追従に際しては、目標横加速度GYTGに基づいてEPSアクチュエータ400からLKA目標アシストトルクTLKが出力される。一方、係るアシストトルクによるドライバの意思に反したステアリングホイル11の操舵を抑制するために、VGRSアクチュエータ200により、操舵輪がLKA補正目標角θLKだけ余分に操舵される。この際、操舵角とロアステアリングシャフト13の回転角との関係には影響が及ばないため、ドライバの操舵に対する車両のロバスト性を低下させることなく目標走行路への追従が実現される。
