无人驾驶汽车的特点？英文双语对照

无人驾驶汽车主要特点

一、安全稳定

安全是拉动无人驾驶车需求增长的主要因素。每年，驾驶员们的疏忽大意都会导致许多事故。既然驾驶员失误百出，汽车制造商们当然要集中精力设计能确保汽车安全的系统。“无人”驾驶系统种类繁多，其中有些根本算不上“无人”，还有些活像是科幻小说中的东西。

防抱死制动系统其实就算无人驾驶系统。虽然防抱死制动器需要驾驶员来操作但该系统仍可作为无人驾驶系统系列的一个代表，因为防抱死制动系统的部分功能在过去需要驾驶员手动实现。不具备防抱死系统的汽车紧急刹车时，轮胎会被锁死，导致汽车失控侧滑。驾驶没有防抱死系统的汽车时，驾驶员要反复踩踏制动踏板来防止轮胎锁死。而防抱死系统可以代替驾驶员完成这一操作——并且比手动操作效果更好。该系统可以监控轮胎情况，了解轮胎何时即将锁死，并及时做出反应。而且反应时机比驾驶员把握得更加准确。防抱死制动系统是引领汽车工业朝无人驾驶方向发展的早期技术之一。

另一种无人驾驶系统是牵引和稳定控制系统。这些系统不太引人注目，通常只有专业驾驶员才会意识到它们发挥的作用。牵引和稳定控制系统比任何驾驶员的反应都灵敏。与防抱死制动系统不同的是，这些系统非常复杂，各系统会协调工作防止车辆失控。

当汽车即将失控侧滑或翻车时，稳定和牵引控制系统可以探测到险情，并及时启动防止事故发生。这些系统不断读取汽车的行驶方向、速度以及轮胎与地面的接触状态。当探测到汽车将要失控并有可能导致翻车时，稳定或牵引控制系统将进行干预。这些系统与驾驶员不同，它们可以对各轮胎单独实施制动，增大或减少动力输出，相比同时对四个轮胎进行操作，这样做通常效果更好。当这些系统正常运行时，可以做出准确反应。相对来说，驾驶员经常会在紧急情况下操作失当，调整过度。

二、自动泊车

车辆损坏的原因，多半不是重大交通事故，而是在泊车时发生的小磕小碰。泊车可能是危险性最低的驾驶操作了，但仍然会把事情搞得一团糟。虽然有些汽车制造商给车辆加装了后视摄像头和可以测定周围物体距离远近的传感器——甚至还有可以显示汽车四周情况的车载电脑——有的人仍然会一路磕磕碰碰地进入停车位。

自动泊车系统是无人驾驶技术的一大成就。通过该系统，车辆可以像驾驶员那样观察周围环境，及时做出反应并安全地从A点行驶到B点。虽然这项技术还不能让人完全放手，让汽车自动载您回家，但毕竟是朝着这个方向迈出了第一步。

Nobody drive the car is main characteristic

One, safe stability

Safety is to pull move nobody to drive the main factor that car demand increases. Annual, of drivers neglectful can cause a lot of accidents. Since driver error 100, car manufacturer people the system that should centralize energy design to be able to ensure the car is safe of course. "Unmanned " drive systematic sort is various, among them some do not calculate at all on " unmanned " , still some mimic is the thing in sci-fi.

Prevent hold dead brake system in the arms to calculate nobody to drive actually system. Although prevent,hold dead brake in the arms to need a driver to operate but this system still can serve as nobody to drive a delegate of systematic series, the partial function that because prevent,adopts dead brake system needed driver hand to move implementation in the past. Do not have when preventing the car scram that adopts dead system, tire can be died by the lock, bring about sideslip of car out of control. When driving to did not prevent the car that adopts dead system, the driver should relapse footplate of trample apply the brake will prevent tire to be locked up dead. And prevent hold dead system in the arms to be able to replace a driver to complete this one operation -- and it is better to touch operation effect than the hand. This system is OK monitoring tire circumstance, when understanding tire is about to lock up dead, make response in time. And reaction opportunity holds more well and truly than the driver. Prevent adopting dead brake system is to lead auto industry to drive toward nobody one of inchoate technologies that way develops.

Another kind nobody drive the system is drawing and stable control system. These systems are not quite conspicuous, only normally professional driver just can realize the effect that they produce. Drawing and the response that stabilize control system to compare any drivers are sensitive. With preventing those who hold dead brake system in the arms to differ is, these systems are very complex, each system can coordinate the job to prevent to lose control of one's vehicle.

When the car be about to when sideslip of out of control or to turn over, stability and traction control system can probe danger situation, start in time prevent accident happening. These systems read the osculatory condition of the travel way that takes a car, speed and tire and ground ceaselessly. Should explore a car will when out of control brings about to turn over likely, stability or traction control system will undertake intervention. These systems and driver are different, they can carry out apply the brake alone to each tire, increase or reduce dynamical output, photograph comparing undertakes operating to 4 tire at the same time, such doing the effect is normally better. When these systems move normally, can make accurate response. Opposite for, driver classics regular meeting operates improper below emergency, adjust excessive.

2, automatic berth car

The reason that car damages, not be accident of great liaison man likely, the little container that produces when berth car however is little touch. Berth car may be dangerous sex lowest drive operated, but still can do the business imbroglio. Although some cars manufacturer is added to car,installed backsight to photograph mix like the head can determine all round the sensor of object distance far and near -- it is OK to still have even indication car all around the car of the circumstance carries computer -- some people still can stumble all the way the ground enters parking space.

System of automatic berth car is the one great success of unmanned road-sense. Adopt this system, car can observe surroundings in that way like the driver, make response in time and nod to B from A dot travel surely. Although this technology still cannot make a person complete let go, make a car automatic carry you to come home, but it is after all forward this direction stepped the first pace.
