In the morning of 22 weitang town, xiangcheng district of suzhou, a 8 km long urban open road, suzhou automobile by tsinghua university institute of independent research and development of unmanned electric after a road test is implemented. According to field experts, driverless cars are still in the experimental phase of research, with a distance from commercial applications, and that the closed road conditions are expected to be commercially available two or three years from now. 
 
At 11:00 a.m., the driverless electric bus began its test trip. The driver starts the engine, press the start button, hands off the steering wheel, and the bus slowly moves forward. From ogelho road to pearl lake road, about 4 kilometers away, the bus is moving along smoothly and smoothly. Test journey, from time to time there are crossing, vehicles and pedestrians, in the face of all open complex traffic environment, unmanned china-pakistan precisely control steering, braking and acceleration of the vehicle, complete with car driving, autonomous overtaking lane changing and change lanes and a series of operations. Traffic signals such as traffic lights can also make accurate judgments and respond accordingly. When turning a corner, the steering wheel automatically hits the direction, and when it turns the corner, it automatically returns to the positive direction, acting as a "invisible man" in driving.

Compared with the ordinary vehicles, suzhou automobile research institute of tsinghua university research and development of the unmanned minibuses are fierce at seems to be no different, but look carefully, or more than a small nose, two small "hat". The technician said that the "little nose" in front of the driverless car was actually a lidar, valued at 70,000 yuan, "which can detect obstacles 30 to 40 meters ahead". The two "little hats" are the devices of the beidou navigation system. 
 
Ding director of the chassis electric control institute of suzhou automotive research institute is the developer of the driverless car. He introduces, the road test today on the unmanned minibuses are equipped with two sets of radar, in addition to the above "nose" laser radar, there is also a hidden in the bottom of the millimeter wave radar, 170 meters in front of the can detect obstacles. "A perception of an immediate environment, a perception of a distant environment. It is because the car carries multiple sensors that can "see" the complicated traffic conditions on the road like human eyes.

The technical key of driverless vehicles is to realize the control of the motor system. "You have to be able to respond to emergencies in a timely manner." For example, for example, the vehicle senses that there are pedestrians in the front and needs to make the brakes; When you encounter a t-junction, you need to make a left-turn or right-turn decision. "The perceived information needs to be quickly converted to a mechanical level, controlling the throttle, braking, steering, and making corresponding movements." 
 
And successfully implemented the unmanned minibuses are the key component of the intelligent driving controller, independent steering and braking actuators is by suzhou institute of tsinghua university, independent research and development has fully independent intellectual property rights. A technological breakthrough to break the foreign monopoly, not only conform to the domestic automobile industry development trend of intelligent, low carbon, informationization, also meet the operation requirements of users safe, efficient and comfortable. 
 
It is understood that after more than a year of trial system, this "tsinghua bloodline" unmanned vehicle, the maximum speed can reach 100km/h, the longest driving range of 30km. 
 
Mr. Ding said that unmanned vehicles are still in the experimental stage and are still a bit away from commercial use. However, he expects to be officially commercially available two or three years down the road. 
 
In the eyes of dean, commercial vehicles can be used for commercial use earlier than passenger cars. "In the future in certain closed areas, such as logistics parks, engineering machinery operations areas, ports and tourist attractions, unmanned technologies and products are expected to be used in the first place."
