Chinese-English Translation:

自适应巡航控制系统,简称 ACC 系统,在传统巡航控制基础上发展起来的新一代汽车驾驶员辅助驾驶系统。将汽车自动巡航控制系统 CCS 和车辆前向撞击报警系统 FCWS 有机结合起来。ACC 不但具有自动巡航的全部功能,还可以通过车载雷达等传感器监测汽车前方的道路交通环境。

Adaptive cruise control system, referred to as ACC system, is a new generation of driver assistance system based on traditional cruise control. The automatic cruise control system CCS and the forward collision warning system FCWs are combined organically. ACC not only has all the functions of automatic cruise, but also can monitor the road traffic environment in front of the car through on-board radar and other sensors.

自适应巡航控制( Adaptive Cruise Control )系统,又可称为智能巡航控制系统,简称 ACC 系统,它是在传统巡航控制基础上发展起来的新一代汽车驾驶员辅助驾驶系统。它将汽车自动巡航控制系统 CCS 和车辆前向撞击报警系统 FCWS 有机结合起来。ACC 不但具有自动巡航的全部功能,还可以通过车载雷达等传感器监测汽车前方的道路交通环境。一旦发现当前行驶车道的前方有其它前行车辆时,将根据本车与前车之间的相对距离及相对速度等信息,通过控制汽车的油门和刹车对车辆进行纵向速度控制,使本车与前车保持合适的安全间距。采用该系统降低了驾驶员的工作负担,大大提高了汽车的主动安全性,扩大了巡航行驶的范围。

Adaptive cruise control system, also known as intelligent cruise control system, referred to as ACC system, is a new generation of driver assistance driving system developed on the basis of traditional cruise control. It combines the automatic cruise control system CCS with the forward collision warning system FCWs. ACC not only has all the functions of automatic cruise, but also can monitor the road traffic environment in front of the car through on-board radar and other sensors. Once it is found that there are other vehicles in front of the current driving lane, it will control the longitudinal speed of the vehicle by controlling the throttle and brake of the vehicle according to the relative distance and speed between the vehicle and the vehicle in front, so as to maintain a proper safety distance between the vehicle and the vehicle in front. The system reduces the driver’s workload, greatly improves the vehicle’s active safety and expands the range of cruise driving.

将巡航控制系统称为最早的驾驶辅助工具之一并不是一件容易的事。它并不总是电子的,并且当然也没有使您祖父的 1982 年凯迪拉克·塞维利亚实现自主,但这是一项革命性的发明。(尽管这是一个有趣的事实:您祖父的别克(Buick )早在 1986 年就拥有第一个信息娱乐系统。)

It is not easy to call cruise control one of the earliest driving AIDS. It wasn’t always electronic, and certainly didn’t make your grandfather’s 1982 Cadillac Seville autonomous, but it was a revolutionary invention. (although it’s an interesting fact: your grandfather’s Buick had its first infotainment system as early as 1986.)

自适应巡航控制将其提升到一个新的水平。与传统的巡航控制系统一样,它可以保持车辆的设定速度,但也可以根据交通流量调整速度。更好的系统可以使您在交通拥堵的情况下完全停下来,并在拥塞减轻时继续运行。通过减轻驾驶员的部分(但不是全部)工作量,这项技术可以使巡航控制更加有用。这就是它的原理,以及它的工作原理。

Adaptive cruise control takes it to a new level. Like the traditional cruise control system, it can maintain the set speed of the vehicle, but it can also adjust the speed according to the traffic flow. Better systems allow you to stop completely in traffic jams and continue to operate when congestion is reduced. By reducing part (but not all) of the driver’s workload, this technology can make cruise control more useful. That’s how it works, and how it works.

在自适应巡航控制系统中寻找什么

What to look for in adaptive cruise control system

概念很简单:使汽车根据周围汽车的行驶速度自动加减速。但是,细节决定成败。

The concept is very simple: make the car accelerate and decelerate automatically according to the speed of the surrounding cars. But details determine success or failure.

为此,汽车必须配备传感器,以使其能够检测附近的车辆和潜在的障碍物。大多数自适应巡航控制系统都使用雷达,地平线上装有高分辨率雷达,尽管也可以使用摄像头和激光雷达(其原理与雷达相同,但具有光波)。您通常可以发现这些集成在格栅中或安装在挡风玻璃后面的摄像机。这些传感器与控制节气门的计算机通信,有时还控制制动器和转向系统。

To this end, the car must be equipped with sensors to enable it to detect nearby vehicles and potential obstacles. Most adaptive cruise control systems use radar, with a high-resolution radar on the horizon, although cameras and lidars can also be used (the same principle as radar, but with light waves). You can usually find these cameras integrated into the grille or mounted behind the windshield. These sensors communicate with the computer that controls the throttle and sometimes the brake and steering systems.

在最基本的形式上,自适应巡航控制技术通常只能通过在前面跟随汽车并保持设定的跟随距离来处理加速和减速。一些汽车制造商已开始将此功能与一种系统捆绑在一起,该系统可以在需要时使汽车完全停止,这在交通拥堵时很方便,和/或提供有限的转向辅助以使汽车居中放置的系统。车道。

In the most basic form, adaptive cruise control technology can only deal with acceleration and deceleration by following the car in front and keeping the set following distance. Some car manufacturers have begun to bundle this feature with a system that can bring the car to a complete stop when needed, which is convenient in traffic jams, and / or a system that provides limited steering assistance to center the car. Vehicle Lane.

自适应巡航控制是电子驾驶辅助装置的核心,一些汽车制造商认为可以构成全自动驾驶的基础。但是,我们离自动驾驶汽车还很近,重要的是不要将自适应巡航控制系统和其他相关技术误认为是完全自主的。这些系统旨在帮助驾驶员,而不是在驾驶员打 ze 睡或计数蓝色汽车驶向其他方向时自己驾驶汽车。

Adaptive cruise control is the core of electronic driving AIDS. Some automobile manufacturers believe that it can form the basis of automatic driving. However, we are very close to autopilot. The important thing is not to mistake the adaptive cruise control system and other related technologies for being completely autonomous. These systems are designed to help drivers, rather than driving their own cars while they are sleeping or counting blue cars in other directions.

有售后自适应巡航控制系统吗?

Do you have after sales adaptive cruise control system?

这是一项不易改装到现有汽车上的技术。自适应巡航控制系统的复杂性使它们超出了售后市场的范围。考虑到这些系统可能意味着行驶的汽车与撞到另一辆汽车后座的汽车之间的差异,对责任的担忧可能会使自适应巡航控制暂时保持在原始设备制造商的范围内。

This is a technology that is not easily adapted to existing cars. The complexity of adaptive cruise control systems makes them beyond the scope of the aftermarket. Given that these systems may mean the difference between a moving car and a car that hits the back seat of another car, concerns about responsibility may keep adaptive cruise control temporarily within the scope of the OEM.

自适应巡航控制最适合谁?

Who is adaptive cruise control most suitable for?

卡迪拉克

Cadillac

像其他汽车制造商提供的系统一样,凯迪拉克的 Super Cruise 可以使汽车加速,转向和制动,而无需驾驶员干预高速公路。但是凯迪拉克是唯一明确声称驾驶员可以放开手的汽车制造商。那是因为凯迪拉克在建立超级巡航方面做得很周到。该系统不仅依赖于一系列摄像机,雷达和激光雷达,而且凯迪拉克还绘制了 20 万英里的高速公路。超级巡航还具有面向驾驶员的摄像头,只有在保持一定水平的驾驶员警觉性的情况下,它才能工作。

Like other car manufacturers’ systems, Cadillac’s super cruise enables cars to accelerate, steer and brake without driver intervention on the highway. But Cadillac is the only car manufacturer that explicitly claims that drivers can let go. That’s because Cadillac is very thoughtful in building super cruise. The system not only relies on a range of cameras, radars and lidars, but Cadillac has also mapped 200000 miles of highways. Super cruise also has a driver facing camera, which works only when a certain level of driver alertness is maintained.

太糟糕了,至少到现在为止,Super Cruise 还没有广泛使用。凯迪拉克在其旗舰 CT6 轿车上启动了该系统,但在扩展至其他车型方面进展缓慢。随着 CT6 车型的停产,凯迪拉克最终宣布,超级巡航将在未来几个月内在 CT4 和 CT5 轿车上销售。这些轿车使用了可以支持“超级巡航”的新电气架构。

Too bad, at least so far, super cruise has not been widely used. Cadillac launched the system on its flagship CT6 sedan, but has made slow progress in expanding to other models. With the production suspension of CT6 models, Cadillac finally announced that super cruise will be sold on cT4 and CT5 cars in the next few months. These cars use a new electrical architecture that supports “super cruise.”.

斯巴鲁

Subaru

斯巴鲁的 EyeSight 系统使用摄像机而不是雷达,从而降低了成本并简化了硬件安装。EyeSight 将自适应巡航控制与车道保持辅助功能,“预碰撞油门管理”功能(可在预期的碰撞发生之前切掉油门)和低速自动紧急制动功能结合在一起。在某些车型上,斯巴鲁还添加了一个面向驾驶员的摄像头,以确保驾驶员在使用这些功能时保持警觉。

Subaru’s eyesight system uses cameras instead of radar, reducing costs and simplifying hardware installation. Eyesight combines adaptive cruise control with lane keeping assist, pre collision throttle management (throttle can be cut off before the expected collision) and low speed automatic emergency braking. On some models, Subaru has also added a driver facing camera to ensure that drivers are alert when using these features.

梅赛德斯·奔驰

Mercedes Benz

梅赛德斯提供了所有汽车制造商中最全面的自适应巡航控制和驾驶员辅助套件之一。其最新的 Distronic Plus 系统可以跟上交通流量,但也可以在走走停停的情况下使汽车完全刹车。如果汽车保持停止状态少于三秒钟,系统将自动恢复驾驶;较长的停靠点需要踩下油门踏板或巡航控制系统的“恢复”按钮。转向辅助功能有助于使汽车保持在其车道中央,并且某些版本的系统可以启动车道变更。

Mercedes offers one of the most comprehensive adaptive cruise control and driver assistance packages of all automakers. Its latest Distronic plus system can keep up with the traffic flow, but it can also bring the car to a full stop and go. If the car remains stopped for less than three seconds, the system will automatically resume driving; for longer stops, it is necessary to press the accelerator pedal or the “resume” button of the cruise control system. Steering assist helps keep the car in the middle of its lane, and some versions of the system can initiate lane changes.

特斯拉

Tesla

特斯拉的自动驾驶系统 吸引了很多争议,考虑到必须将驾驶员保持在循环中,这个名称有点误导,但它仍然是同类中最先进的系统之一。除了跟随交通并自动将汽车保持在其车道之外,Autopilot 还可通过转向信号灯来执行车道变更,并协商一些高速公路下坡道。特斯拉具有使用该系统从汽车中提取数据并启动空中软件更新的能力,这意味着随着时间的推移,Autopilot 具有巨大的改进潜力。

Tesla’s autopilot system has attracted a lot of controversy. Considering the need to keep drivers in circulation, the name is a bit misleading, but it is still one of the most advanced systems in its kind. In addition to following the traffic and automatically keeping the car in its lane, autopilot can also perform lane changes through turn signals and negotiate some freeway downramps. Tesla has the ability to use the system to extract data from cars and start software updates in the air, which means that autopilot has great potential for improvement over time.

沃尔沃

Volvo

毫不奇怪,一个痴迷于安全性的汽车制造商是自适应巡航控制的早期采用者。沃尔沃还是最早将该技术与自动紧急制动结合起来的汽车制造商之一,这使汽车既可以自动跟随前方车辆,也可以在遇到障碍物时自动制动。沃尔沃最新的 Pilot Assist II 系统无需跟踪前方车辆,可以将汽车保持在车道中央,并且可以以最高 80 mph 的速度运行。

Not surprisingly, a safety obsessed automaker was an early adopter of adaptive cruise control. Volvo is also one of the first car manufacturers to combine this technology with automatic emergency braking, which enables cars to either follow the vehicle in front or brake automatically when encountering obstacles. Volvo’s latest pilot assist II system doesn’t need to track the vehicle ahead, keeps the car in the middle of the lane and can run at up to 80 mph.
