Autonomous lane change, automatic identification of traffic lights at intersections, fixed-point docking... The world’s first driverless bus, under open road traffic conditions, successfully operated for the first time without human intervention. 
The large-scale Yutong coaches for this self-driving test start from the Jialuhe station of Zhengkai Avenue, an intercity expressway linking Zhengzhou City and Kaifeng City in Henan Province, with 26 signal-light intersections under a completely open road environment. Completed a series of test subjects such as follow-up driving, autonomous lane changing, adjoining lane overtaking, automatic identification of traffic lights at intersections, fixed-point docking, etc., and traveled 32.6 kilometers, with a maximum speed of 68 kilometers, and successfully reached the designated end point. There was no manual intervention throughout. 
According to industry experts, the biggest advantage of self-driving cars is to enhance the active safety performance of vehicles. Under the background of modern intelligent transportation development, high-intelligence vehicles represented by autonomous driving can completely eliminate traffic accidents. 
Secret bus is how autopilot autopilot <br> <br> the road test run buses, Yutong Bus, including the General Staff by 61 other Chinese Academy of Engineering academician Li Deyi where the domestic passenger car industry leader in the launch of the joint research and development The development of the vehicle takes 3 years and is finally scheduled for field testing in August this year. It is understood that the core of the successful driving of the car under unmanned driving conditions is the intelligent driving system of the vehicle. It consists of three main components: the intelligent host controller, intelligent perception system, and intelligent control system. It serves as the brain of the bus. The functions of the eyes, ears, and limbs are coordinated with each other to achieve autonomous driving.
Taking the recognition and waiting for the traffic light as an example, the IntelliSense system relies on cameras, lidars, and lasers that are distributed around the vehicle, creating a 360 dead-end detection area to meet the vehicle's perceived needs for the surrounding environment under various complex road conditions. At the same time, the vehicle drive system can respond to the virtual throttle command issued by the "brain" master controller. If it is determined to be green, it will be accelerated and passed directly later. If it is considered that the intersection is in red or yellow, it will slow down in advance until the intersection stops. .
In the event of an emergency, the autonomously driven passenger car will adopt different decelerations for braking according to the degree of urgency of the situation to minimize the occurrence of rear-end collision accidents. Especially in safe driving, rely on the "ear" radar around the car to detect the relative speed and distance between the front and rear obstacles and the vehicle, enable early warning measures, and adjust acceleration and deceleration measures based on this information.
Excellent driving habits can drive vehicles to reduce energy consumption. Autopilot robot drivers can achieve the best driving habits in response to various situations while learning from the human driver, minimizing energy consumption and reducing costs. protect environment.
Li Deyi, Academician of the Chinese Academy of Engineering and head of the Automated Driver Bus Research Group, said: "With a series of intelligent sensing and other means, autonomous driving of intelligent vehicles can greatly enhance the vehicle's active safety performance, correct driver's wrong driving behavior, and intelligent traffic in the future. With the prospect of development, smart cars will eventually completely eliminate traffic accidents."
The status of the only one involved autopilot passenger car company <br> <br> It is understood that the commissioning of the autopilot belongs Yutong buses, since the last three years, domestic and foreign research through research Yutong Bus autopilot Technical Analysis The research route of Yutong Bus autopilot technology was determined, and a research and development agreement was signed with Academician Li Deyi of the General Staff Department 61, and a million yuan was invested in the development of the “human-computer interaction projectâ€.
Yu Tong, deputy chief engineer of Yutong Bus, said: “Yutong’s autonomous driving of passenger cars is divided into three phases: basic movement control, simplest road condition driving, and track environment driving. The first phase of technical research is currently underway. The application of driving technology and mass promotion."
It is understood that the self-driving R&D technology of China's autonomous car companies is being developed in cooperation with universities, research institutes, and overseas institutes of domestic universities. At this stage, there are five autonomous car companies in the field of autonomous driving of private cars. Yutong is currently The only domestic auto company that involves autonomously driving passenger cars.
Yu Dengfeng, head of the technical research department of Yutong Bus, said: “The intelligent car and intelligent transportation are the major trends in the future. During autonomous driving, the vehicle autonomously detects road conditions and changes, plans alternative routes, self-corrects driving behavior, and finally realizes zero traffic. Congestion and zero accidents."
