Title: (EN) Driving support system of vehicle
(ZH) 车辆的行驶辅助设备
Abstract: front page image
(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 theta LK 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.
(ZH)

在不导致车辆行为不稳定的情况下使车辆追随目标行驶路线。车辆(10)包括作为车轮转向角可变装置的VGRS执行器(200)以及作为转向转矩辅助装置的EPS执行器(400)。在进行对目标行驶路线的追随时,基于目标横向加速度GYTG从EPS执行器(400)输出LKA目标辅助转矩TLK。另一方面,为了抑制由该辅助转矩引起的违反驾驶员意思的转向盘(11)的转向,通过VGRS执行器(200)使转向轮额外转向LKA修正目标角θLK。此时由于对转向角和下部转向轴(13)的转角的关系不产生影响,因此可在不降低相对于驾驶员转向的车辆的鲁棒性的情况下实现对目标行驶路线的追随。
