摘要： 某车型在智能辅助驾驶开发过程中，车道保持辅助（Lane Keeping Assist, LKA）在直 线行驶时，驾驶员在缓慢操作方向盘时 LKA 的控制力矩与驾驶员转向操作力相互干预，产生 不舒适的感觉。针对 LKA 功能影响转向不舒适的问题，论文通过分析影响 LKA 使之产生对 转向有不利因素的影响，主要从影响 LKA 功能的横摆加速度传感器、试验道路横向坡度进行 研究分析，结果表明，横摆角速度及试验道路的横向坡度对 LKA 功能有影响，从而影响汽车 转向系统，导致在行驶过程中产生不舒适性。

关键词: 车道保持辅助；横摆加速度；道路横向坡度

Abstract: In the development process of intelligent assistant driving, when Lane Keeping Assistant (LKA) is driving in a straight line, when the driver operates the steering wheel slowly, the control torque of LKA interferes with the steering force of the driver, resulting in uncomfortable feeling. Aiming at the problem that LKA function affects steering discomfort, this paper analyzes the influence of LKA on steering. It mainly studies the yaw acceleration sensor which affects LKA function and the transverse slope of test road. The results show that the yaw rate and the cross slope of test road have influence on LKA function, which leads to the interference effect of LKA function on automobile steering system, resulting in discomfort during driving.

Key words: Lane keeping assist; Yaw rate; Road cross slope
