After completing the 114-kilometer Beijing-Tianjin high-speed drive, the "Jiangjiao Mengshi III" driverless smart car modified by the black Hyundai Tucson off-road vehicle drove off the Tianjin Dongli toll station.
At 10:50 am yesterday (24th), after completing the 114-km Beijing-Tianjin high-speed drive, this "Jiangjiao Mengshi III" driverless smart car modified by the black Hyundai Tucson off-road vehicle was in Tianjin Dongli The toll gate is next. Throughout the test, "Jiangjiao Mengshi III" achieved automatic driving without human intervention, and successfully completed the predetermined test target.

Lane changing overtaking brake steering completed successfully
Yesterday morning, from the Beijing-Tianjin Expressway Taihu Toll Station to the Toli Toll Station, the "Jiangjiao Mengshi III" drove a total of 114 kilometers in an unmanned state, achieving 12 autonomous overtakings and 21 passive overtakings. 36 times, 1816 accelerator operations, 30 brake operations, 11812 steering operations, fuel consumption 9.69 liters, total autonomous travel time 85 minutes, average speed 79.06 kilometers per hour, maximum speed 105 kilometers per hour.
According to the test requirements, the types of lanes for smart cars include four-lane, three-lane, two-lane, and ramp; the main test subjects are line-based driving, following driving, autonomous lane change, adjacent lane overtaking, autonomous overtaking, manual instruction driving six section. To ensure safety, the smart car is equipped with an emergency control device, which can immediately implement manual forced intervention in an emergency.
"There is a toggle button in the car. In the case of automatic driving, it is useless for people to touch the steering wheel." Professor Xu Youchun of the Military Transportation Institute said.
Interestingly, the research team originally prepared a "barricade car" and wanted to run in front of the unmanned car to help it complete the overtaking and other operations. However, due to the complicated conditions of the high-speed boarding and the large number of vehicles on the Beijing-Tianjin high-speed on weekends, The owners of private cars didn't notice the driverless car at all, so there was a situation where the private car quickly overtakes after the driverless smart car. Due to the previous trial and error and precise design, the unmanned vehicle detected these behaviors calmly and completed the movements such as penetration and overtaking.

Smart cars are expected to be applied in more fields
At the test site, Li Deyi, the academician of the Chinese Academy of Engineering who was the first to experience unmanned vehicles, said that the application of driverless vehicles is multi-faceted, not that all cars are driverless, but that self-driving technology is radiated to manned driving. To solve the problems of car safety and urban congestion. "For example, the sweeping vehicles in the city can use unmanned driving in the early morning to save manpower costs." It is reported that the Military Transportation Academy will use the unmanned vehicle technology to conduct another urban road driving test next year, "strive for more traffic lights And crossroads, in the future, we will study snow driving and use infrared rays to drive at night. "Academician Li introduced.
"The ultimate goal of unmanned vehicles is to turn cars into robots." Professor Xu told reporters that the existing reversing radar, automatic parking or cruise control system and other tools that still belong to the electronic product category require human maintenance, and There are essential differences in smart cars. "Our development goal is to adapt to people and drive more. Unmanned vehicles will actively imitate the driving habits of drivers."
