March 10, a car company executives personally test self-driving car webcast, screened the circle of friends. This is Changan opened the first domestic L3 level of automatic driving mass production experience. In the open road section, the company's president personally experienced it on the newly released UNI-T model. The test process, many times to free both hands and feet, see people scared, while through the network live as onlookers of the netizens are greatly addicted.

From the earliest Hollywood sci-fi blockbusters to the application in daily life, self-driving cars let people personally feel what is called a dream come true. Compared with their foreign counterparts, Chinese car companies have been able to make a name for themselves in the field of self-driving technology, and have launched their own fist products.

Leading the way with Changan's L3 autonomous driving

It must be said that in the field of autonomous driving technology, Changan Automobile is a deserved leader. As early as 2009, Changan opened the research and development of automatic driving.In 2016, Changan Automobile became the first automobile enterprise to realize 2000 kilometers of unmanned long-distance testing; in 2018, it realized the L2 level of IACC integrated adaptive cruise control; in 2019, it realized fully automated remote-controlled parking and realized the mass production debut. The first test drive experience of Changan's first L3 in a production car is a sign that China's auto industry has entered the era of autonomous driving.

Applying the L3 automatic driving system on the UNI-T model, it can realize a long time to take off the feet, hands, and eyes in a specific electronic fence (including highway and city road), in a congested environment, until the system prompts the manual takeover, the highest speed that can be supported is 40 km/h; if the user still does not take over, it will execute the risk mitigation strategy, and decelerate and even stop directly.

In addition, the system can also be realized with the front car deceleration parking and automatic restart. Within 3 minutes of parking, it can automatically follow the car to start. At the same time the system can automatically adjust the distance with the surrounding vehicles.

It is worth mentioning that the Changan L3 automatic driving system can also realize lane change monitoring (speed higher than 50 kilometers per hour), so as to control the vehicle to change lanes automatically. In this process, there is absolutely no need for the driver's hands and feet to control, but the system will monitor the driver's line of sight and can not take off his eyes.

The most significant enhancement of L3 automatic driving is that the vision can no longer focus on road conditions, road conditions and the corresponding driving behavior are all handed over to the on-board system to identify the completion. In the car market reddit editorial opinion, Changan L3 level automatic driving technology is not only embodied to the high-tech aspects, more importantly, has been realized in mass production. It seems that in terms of automatic car driving, Changan Automobile has once again succeeded in leading the way.

Dongfeng Sharing-X on the front line of epidemic prevention

A few days ago, in Wuhan, where the epidemic was the most serious, Dongfeng's Technology Center launched a driverless extermination vehicle project supported by Dongfeng Sharing-X?mobile travel service technology platform, which is called a successful actual combat of driverless cars.

In order to better serve the epidemic prevention work of the new crown pneumonia epidemic, with the Sharing-VAN driverless sightseeing car as the basic platform, the temporary anti-epidemic service team optimized and modified the vehicle in terms of auto-pilot and 5G cloud control, and at the same time added a 16L large-capacity fully-automatic disinfectant sprayer in order to realize the whole driverless disinfection operation on high-risk roads in the observation area.

It is understood that, since the start of the commissioning operation of the entire vehicle on March 5, Sharing-VAN continues to carry out the park disinfection operation services for the "Jingkai ZhiZhuang 2045-Innovation Valley" isolation point for rehabilitated persons. With the high-precision application of combined positioning and efficient transmission of 5G signals, Sharing-VAN can safely and efficiently cope with complex road conditions and travel freely among high-rise buildings. On the total length of 1.1 kilometers of disinfection routes, it executes 3 times of disinfection work in the morning, midday and evening every day, covering an area of about 10,000 square meters in a single disinfection. This saves a lot of labor and material resources and also avoids manual contact, reducing the risk of infection.

It is reported that, thanks to the L4 level of highly automated driving technology and 5G remote driving technology, in the Dongfeng Technology Center 5G parallel driving accusation center scheduling console, you can realize the "Jingkai ZhiZhuang 2045-Innovation Valley" rehabilitation personnel isolation point running Sharing-VAN vehicles for remote monitoring and vehicle control. Remote monitoring and vehicle control. When Sharing-VAN completes the operation of going straight, turning, and stopping at a fixed point at the isolation point, the driver sitting in the simulated cockpit in the Technology Center of Dongfeng Company is operating the steering wheel, giving oil, braking, and staging a real scenario of "a person sitting at home and a car driving on the road".

The epidemic has given rise to unmanned delivery vehicles "big practice"

In the case of unmanned operation, a delivery vehicle can be driven to the designated destination. This sounds like a science fiction movie, but in this epidemic, Jingdong unmanned delivery car is such a heroic performance. On the streets of Wuhan, Jingdong unmanned delivery vehicles departed from the logistics station, deftly dodging vehicles and pedestrians, and smoothly delivered medical supplies to Wuhan hospitals.

It is understood that at the end of 2019, Jingdong's unmanned vehicles carried out a fully L4-level trial operation with mixed pedestrian and vehicle traffic and open roads in Tongzhou and Fangshan, Beijing, and announced that it had made a phased breakthrough. The Jingdong unmanned delivery vehicle applied to the streets of Wuhan this time is one of the research and development achievements of the Jingdong X Division in the field of logistics. After the distributor enters the order number, it will automatically select the appropriate box into the courier car and transported to the designated location, notify the user to pick up, greatly solving the last kilometer of logistics and distribution distribution problems.

In addition to the Jingdong unmanned delivery vehicle to participate in the epidemic of real combat, Jiangxi Province, unmanned disinfection delivered to the urban management department for community and urban village disinfection and elimination work. The disinfection car is electrically driven, with a range of 8 hours, fully loaded with 1.2 tons of disinfectant water, and can carry out a full range of disinfection operations in communities and urban villages.

In addition, by the Shenzhen family company developed a driverless logistics vehicle "Quartet" can not only undertake the logistics warehouse and wards, wards and refuse transport tasks, but also can undertake the supermarkets and small intervals between the material material transportation tasks. It is understood that "Quarto" a car can be loaded with 75 small boxes, each box can be loaded with 20 pounds of goods, a single trip can be distributed 1500 pounds of vegetables and fruits.

Red dot comment: "Practice is the only standard for testing the truth", this sentence is very appropriate for the development of China's self-driving cars. Whether it is Changan UNI-T model L3 self-driving system, or Dongfeng Sharing-X?, both represent the technological high point in this field.

For China's automobile industry, not only in the automobile automatic driving to dominate, but also applied to the actual combat, and partially realized the mass production. It is understood that in this epidemic newly put into use in the Vulcan Mountain, Thunder Mountain two hospitals are not only covered by the 5G network, but also the introduction of low-speed self-driving cars and robots, used to undertake some of the patient transportation and distribution of goods, including the transportation of patients, the transmission of laboratory tests, medicines, and patient catering, etc.

This is the first time in the history of the world's most famous automobile industry.

Considering the ambitious blueprints of smart streets and smart cities proposed by some car companies, which are still in the research and development stage in other countries, China has already been applied in the real world and achieved the expected results, thus also providing more valuable experience for China's autonomous vehicle driving technology.
