带停走功能的自适应巡航控制系统（ACC Stop & Go）和奥迪预防式整体安全系统（Audipre sense）是新奥迪A8家族驾驶辅助系统的核心。ACC Stop & Go通过雷达和摄像头对前方路况进行监测，在0到250公里/小时的速度范围内，ACC Stop & Go可以在不逾越设定速度的前提下，通过自动加速或自动减速，保持与前车的距离。当前方出现拥堵、前车减速停下时，ACC Stop & Go也会自动刹车减速，直至完全停止。
Adaptive cruise control system (ACC stop & go) with stop and go function and Audi sense are the core of new Audi A8 family driving aid system. ACC stop & go monitors the road conditions in front by radar and camera. In the speed range of 0 to 250 km / h, ACC stop & go can maintain the distance from the vehicle in front by automatic acceleration or deceleration without exceeding the set speed. ACC stop & go will also automatically brake and decelerate until it stops completely when there is congestion in the front and the vehicle in front slows down and stops.
停车后，ACC Stop & Go系统会根据情况做出判断：如果只是短时停车，前车起步后，本车会自动起步跟上；如果停车时间较长，前车起步后，本车驾驶员需要轻踩油门踏板或轻触定速巡航控制杆才能再次起步。在车辆起步的过程中，ACC Stop & Go系统会通过前保险杠上的超声波传感器判断车前周围是否有障碍物，如果有，则会停下。
After parking, ACC stop & go system will make a judgment according to the situation: if the car stops for a short time, the car will start automatically after the front car starts; if the parking time is long, the driver of the car needs to step on the accelerator pedal or touch the cruise control lever to start again. In the process of starting the vehicle, ACC stop & go system will judge whether there are obstacles around the front of the vehicle through the ultrasonic sensor on the front bumper, and if so, it will stop.
新奥迪A8装备的ACC Stop & Go系统是一套非常复杂、但是面向未来的驾驶辅助系统。它通过车上其他27个传感系统的数据进行分析，其中更重要的信息是来自于两个雷达传感器的信息。雷达位于车前端的下部，频率范围为76至77 GHz，可探测到前方约250米、夹角为40°的扇形区域。而车内后视镜背面的摄像机则可探测到车前约60米、角度同样为40°的区域。系统通过获取、分析这些信息及时做出反应，主动对驾驶者提供帮助。ACC Stop & Go有四种跟车距离可选择，驾驶者可以通过MMI系统设定或更运动的跟车距离。
The ACC stop & go system of the new Audi A8 is a very complex but future oriented driving aid system. It analyzes the data of 27 other sensor systems on the vehicle, and the most important information is the information from two radar sensors. The radar is located in the lower part of the front end of the vehicle, with a frequency range of 76 to 77 GHz. It can detect a fan-shaped area about 250 meters ahead with an angle of 40 degrees. The camera on the back of the interior rearview mirror can detect an area about 60 meters in front of the car with an angle of 40 degrees. By acquiring and analyzing these information, the system can make timely response and provide help to drivers. ACC stop & go has four following distances to choose. The driver can set the most comfortable or moving following distance through MMI system.
