Systems and methods for smoothing automatic lane change (ALC) operations. After receiving a request of the ALC, the task planner sends an ALC head-up signal to a transverse controller. The task planner then initiates an operation of trust establishment for a pre-programmed time and waits for ALC ready signals from lateral control. When an ALC head-up signal is received, a lateral control computes a ready index (RALC) as a function of the requesting ALC, the current trajectory, and the lane centering control path. The lateral control transmits an ALC ready signal when the RALC is less than or equal to a ready threshold Rt. When the RALC is greater than Rt, the lateral control generates a steering correction and applies the steering correction to reduce the RALC, thereby stabilizing the vehicle and sending an ALC ready signal. Upon receiving an ALC ready signal, an ALC operation is performed.

    用于平滑自动车道变换(ALC)操作的系统和方法。任务规划器在收到ALC的请求后,向一个横向控制发送一个ALC平视信号。任务规划器随后开始信任建立的操作,持续一段预编程的时间,并等待来自横向控制的ALC就绪信号。当收到ALC平视信号时,横向控制计算就绪指数RALC,作为请求ALC、当前轨迹和车道居中控制路径的函数。当RALC小于或等于就绪阈值Rt时,横向控制发送ALC就绪信号。当RALC大于Rt时,横向控制产生转向校正,并应用转向校正来减小RALC,从而稳定车辆并发送ALC就绪信号。一旦接收到ALC就绪信号,就执行ALC操作。
