早在1970年就开始在美国开始应用的自动巡航技术,实际上迈开了车辆无人驾驶的第一步。而根据道路状况自动判断与前车距离并根据路况变换速度,是向无人驾驶又迈进了一步。现在,车辆无人驾驶正进入第三阶段——车辆已经能够实现自动驾驶,尽管驾驶室内依然还有驾驶员随时接管操控。在这一阶段,在正常自动行驶状态下,驾驶员不需要干预车辆驾驶,而是可以休息或者读书看报。在第四阶段,车辆能够在市
The auto-cruise technology, which began as early as 1970 in the United States, actually took the first step toward driverless driving. According to the road conditions automatically determine the distance with the car in front and according to the speed of change, is to move to a step without driver. Now, the driverless vehicle is entering the third phase - the vehicle has been able to achieve automatic driving, although there are still drivers in the cab at any time to take over the control. At this stage, under normal automatic driving conditions, the driver does not need to intervene in driving the vehicle, but can rest or read a newspaper. In the fourth stage, the vehicle can be in the city
