From the earliest Hollywood sci-fi blockbuster to the application in daily life, self-driving cars let people personally feel what dreams come true. Compared with foreign counterparts, China car companies have a good strength in the field of autonomous driving technology, and have launched their own fist products.
The dominant Chang 'an L3 autopilot
It must be said that Changan Automobile is a well-deserved leader in the field of autonomous driving technology. As early as 2009, Chang 'an began the research and development of autonomous driving. In 20 16, changan automobile became the first automobile enterprise to realize the 2000 km long-distance driverless test. 20 18 to realize L2 IACC integrated adaptive cruise system; 20 19 realized automatic remote parking and began mass production. This time, Changan put L3 on the production car for the first time, which indicates that China automobile industry has entered the era of autonomous driving.
With the L3 autopilot system on UNI-T, you can take off your feet, hands and eyes for a long time in specific electronic fences (including highways and urban roads) and congested environments until the system prompts you to take over manually. The maximum support speed is 40 km/h; If the user still does not take over, the risk mitigation strategy will be implemented to directly slow down or even stop the vehicle.
In addition, the system can also slow down and stop in front of the vehicle and automatically restart. Within 3 minutes of parking, it can be automatically started with the car. At the same time, the system can automatically adjust the distance from the surrounding vehicles.
It is worth mentioning that Chang 'an L3 autopilot system can also realize lane change monitoring (the speed is higher than 50km/h), so as to control the vehicle to automatically change lanes. In this process, there is no need to control the driver's hands and feet, but the system will monitor the driver's line of sight and can't take off his eyes.
The most remarkable improvement of L3 autopilot is that the line of sight can no longer pay attention to the road conditions, and the road condition judgment and corresponding driving behavior are all given to the on-board system for identification. In the view of Bian Xiao, the red dot of the automobile market, Changan L3 autonomous driving technology is not only reflected in the high technology content, but also realized mass production. It seems that Changan Automobile has once again successfully led the way in automatic car driving.
Dongfeng sharing -X is in the front line of epidemic prevention.
A few days ago, in Wuhan, where the epidemic was the most serious, the technical center of Dongfeng Company launched Dongfeng Sharing-X? The unmanned vehicle project supported by the mobile travel service technology platform can be called a successful actual combat of driverless cars.
In order to better serve the epidemic prevention work in COVID-19, the temporary epidemic prevention service team optimized and modified the vehicles from the aspects of automatic driving and 5G cloud control on the basis of sharing the van unmanned sightseeing bus, and installed a 16L large-capacity automatic disinfection sprayer, which realized the whole unmanned disinfection work of high-risk roads in the observation area.
It is understood that since the commissioning and operation of the whole vehicle began on March 5, Sharing-VAN has continued to provide disinfection services in the park for the "2045 Innovation Valley by Kaizhi" isolation point. The high-precision application of combined positioning and the efficient transmission of 5G signals enable Sharing-VAN to deal with complex road conditions safely and efficiently and walk freely between tall buildings. On the full-length 1. 1 km disinfection route, disinfection work is carried out three times a day in the morning, at noon and at night, and the coverage area of single disinfection is about 10000 square meters. It not only saves a lot of manpower and material resources, but also avoids manual contact and reduces the risk of infection.
According to reports, thanks to the L4-level highly automatic driving technology and the 5G remote driving technology, the shared van vehicles running in the isolation point of the "Kaizhizao 2045 Innovation Valley" rehabilitation personnel can be remotely monitored at the dispatching desk of the 5G parallel driving command center in the technical center of Dongfeng Company. When Sharing-VAN completed the operations of going straight, turning and stopping at the isolation point, the driver sitting in the simulated cockpit was operating the steering wheel, supplying oil and braking in the technical center of Dongfeng Company, and staged the real scene of "people sitting at home and driving on the road".
The epidemic gave birth to the "big training" of unmanned delivery vehicles.
In the case of unmanned driving, the delivery vehicle can drive to the designated destination by itself. It sounds like a science fiction movie, but in this epidemic, JD.COM unmanned delivery vehicle is such a brave performance. On the streets of Wuhan, JD.COM unmanned delivery vehicles set off from the logistics station, deftly avoiding vehicles and pedestrians, and successfully delivered medical supplies to Wuhan Hospital.
It is understood that at the end of 2065438+2009, JD.COM unmanned vehicles carried out full L4 trial operation in Tongzhou and Fangshan, and announced a phased breakthrough. The JD.COM unmanned delivery vehicle, which was applied in the streets of Wuhan this time, is one of the research and development achievements of JD.COM X Division in the field of logistics. After the delivery clerk enters the order number, he will automatically select the appropriate box and put it in the express truck to inform the user to pick it up, which greatly solves the distribution problem of the last mile of logistics distribution.
In addition to the fact that unmanned delivery vehicles in JD.COM participated in the actual epidemic, unmanned disinfection in Jiangxi Province was put into the urban management department for disinfection and sterilization of communities and villages in the city. The disinfection vehicle is driven by electricity, with a battery life of 8 hours and full of disinfection water 1.2 tons, which can disinfect all communities and villages in the city.
In addition, the unmanned logistics vehicle "Kuafu" developed by a company in Shenzhen can not only undertake the transportation tasks of logistics warehouses and wards, wards and garbage stations, but also undertake the transportation tasks of materials between supermarkets and communities. It is understood that "Kuafu" can hold 75 small boxes in one car, each box can hold 20 kilograms of goods, and a single trip can transport 1.500 kilograms of vegetables and fruits.
Red Dot comments: "Practice is the only criterion for testing truth", which is very appropriate for the development of self-driving cars in China. Whether it's Changan UNI-T L3 autopilot system or Dongfeng Sharing -X? Both represent the technical commanding heights in this field.
For China's automobile industry, it is not only the leader of autonomous driving, but also applied to actual combat, and partially achieved mass production. It is understood that the two hospitals, Vulcan Mountain and Raytheon Mountain, which were newly built and put into use in this epidemic, not only covered the 5G network, but also introduced low-speed self-driving cars and robots to undertake the work of transporting some patients and distributing goods, including transporting patients, transporting tests, medicines and patient catering.
Reminiscent of the grand blueprint of smart streets and smart cities put forward by some car companies, China has been applied in other countries or in the research and development stage, and achieved the expected results, thus providing more valuable experience for China's self-driving car technology.
