高中英语译林版选修一Unit 3 课文原文+中文翻译 U3 Reading Self-driving cars-destination known? 自动驾驶汽车——目的地已知吗? Mr Zhang casually glances at the empty driver's seat and says,“Destination Grand Hotel. Family mode. Start." The car responds immediately, easing smoothly into the busy traffic and avoiding obstacles on the road. Inside the car, the family have chosen their entertainment from a pop-up display panel, ready for the journey ahead. This imagined scene provides a likely future reality for self-driving cars, also known as autonomous vehicles. 张先生漫不经心地看了一眼空荡荡的驾驶座，说道：“目的地格兰酒店。家庭模式。出发。”汽车立即响应，平稳驶入繁忙的车流，避开路上的障碍。车里面，一家人已经在弹出式显示面板上选好了娱乐项目，为前方的旅途作好准备。这个想象中的场景展示了自动驾驶汽车，也叫自主汽车，一种可能的未来的现实。 However, before this evolution in transport becomes a revolution, it must be fully understood how self-driving cars work. Put simply, self-driving cars must “see” and “behave” appropriately to be safe on the road. They do this through various hardware and deep-learning artificial intelligence (AI). Cameras as well as sensors like radar and lidar capture a variety of data from the external environment. Once the data is sent to the AI system, the“brain" of the self-driving car, it is analysed and put together like a puzzle so that the car can“see" its surroundings and determine its position. Meanwhile the AI system identifies patterns from the data and learns from them. An action plan is then created to instruct the car how to "'behave" in real time: stay in the lane, move into another one, speed up or slow down. Next, the necessary mechanical controls, such as the accelerator and brakes, are activated by the AI system, allowing the car to move in line with the action plan. 然而，在这种交通方式的变革成为一场革命之前，必须充分了解自动驾驶汽车的工作原理。简言之，要想在路上安全行驶，自动驾驶汽车必须恰当地“看”和“做”。它们通过各种硬件和深度学习人工智能(AI) 来实现。摄像头以及雷达、激光雷达等传感器从外部环境中获取各种数据。数据一旦发送到人 工智能系统，即自动驾驶汽车的“大脑”，立即被分析并像拼图一样被拼凑起来，于是汽车就能“看到”周围的环境并确定自身方位。同时，人工智能系统从数据中识别出模式，从中学习。然后份行动计划被创建出米，用以指导汽车如何实时“行动”：沿车道行进，变道，加速或减速。接下来，人工智能系统激活油门、利车等必要的机械操纵装置，让汽车按照行动计划行驶。 This may sound perfect in theory, b
