As early as a few years ago, someone asked Musk: When do you think self-driving cars will be approved? Musk’s answer surprised everyone: “I don’t care when autopilot is approved. What I care about is the moment when humans are prohibited from driving.” Many people questioned Musk’s remarks, thinking that this will never happen! Because no one can imagine sitting in a car without a steering wheel. Musk’s response was: “A hundred years ago, no one could imagine riding an elevator without an elevator administrator. Now, what you can’t imagine is an elevator with an elevator administrator.” I don’t hear this. What do you think about the remarks of "mad men" in the industry? Facts have proved that, whether we accept it or not, autonomous driving is entering our lives unstoppable.

SAIC Hongyan "5G+L4" Smart Heavy Truck

The recent commercial operation of SAIC Hongyan's "5G+L4" smart heavy trucks in Shanghai Yangshan Port is a typical example. Autonomous driving is a high-tech product that combines modern networks and big data. Not many people understand the cutting-edge technologies. Put aside those complicated and difficult technologies, start with SAIC Hongyan's "5G+L4" smart heavy truck, and from the perspective of the truck driver, talk about SAIC Hongyan's "5G+L4" smart heavy truck and autonomous driving.

One, 70 seconds to complete the reversing and storage of the novice headache

This question is often mentioned in our "Old Road Truck Driving Lecture Hall" training: What is the most difficult operation link for heavy truck semi-trailer driving? Many novice card clubs answered unanimously: reversing and warehousing.

That's right, the semi-trailer is different from the truck, and its two-body body structure is destined to accurately grasp the forward and reverse directions during the reversing process. Furthermore, its overly long body can easily cause the driver to panic when reversing. This technology is definitely not a complete apprenticeship after a few months of practice in a driving school. And facts have proved that there is no shortcut to solve this technical problem, the only way is: study hard.

And we saw at the Shanghai Yangshan Port Hongyan “5G+L4” smart heavy truck automatic reversing and warehousing test site: a 2.55 meter wide Hongyan heavy truck was poured into a 2.7 meter wide garage, centimeter-level positioning, precise parking (+- -3cm), the overall warehousing success rate is as high as 100%, and the average time for reversing is 70 seconds.

This level has reached or exceeded the reversing efficiency and accuracy of the "old driver". What is gratifying is that with this technology empowering heavy-duty truck driving, the problem of reversing and warehousing has been easily solved. Can novice drivers still use it to help reversing and warehousing?

2. Lidar and machine vision make trucks have no blind spots

The blind spot accident response method is a key part of the "Old Road Truck Driving Lecture Hall" safe driving training. The blind spot is a pain point that seriously troubles truck driving, especially the right turn blind spot accident. Among all the casualties of trucks, accidents caused by blind spots accounted for the highest proportion. Among them, the blind spots caused the largest amount of casualties when turning right.

Take Shenzhen as an example. In 2018, there were 88 accidents involving heavy trucks in Shenzhen, with 91 deaths, of which 47 were accidents caused by blind spots, accounting for more than half! In the safety publicity of the traffic control department, the blind spot on the right side of a large truck is even compared to: Hukou (as shown below). This analogy is very apt. The heavy truck is tall and long, and the sight line of the cab is limited, so that the driver cannot see all the surrounding conditions of the vehicle when sitting in a fixed position. If the line of sight is not visible, it is equivalent to blindly driving. When a large truck turns right into the blind zone, it is really as dangerous as being in the mouth of a tiger!

Aiming at blind areas of driving sight, Hongyan’s “5G+L4” smart heavy truck provides such a solution: visual perception system + lidar system + millimeter wave radar system + satellite and inertial navigation and other heavy truck perception systems, allowing the vehicle to control itself The surrounding conditions are well known.

It eliminates blind spots in the driver's sight by comprehensively applying technologies such as lidar, machine vision, artificial intelligence, Beidou navigation, and 5G-V2X vehicle-linked communications. It has opened up a complete control loop from the electronically controlled chassis, engine, to the intelligent driving system, and realized L4 level automatic driving in specific scenarios in the port area.

3. Queue driving completely bid farewell to "fatigue driving"

In addition to driving blind spots, fatigue driving is also an industry stubborn disease. Everyone's energy is limited. After driving for a long time, it is inevitable for anyone to get sleepy and nap, especially on the highway of Yimapingchuan, where there are no slopes, no sharp bends, and smooth traffic flow. No one can escape sleepiness after driving for a long time. The invasion. What is certain is that if a person continues to drive a vehicle in a sleepy state, the accident will follow.

According to statistics, among the traffic accidents that occur in China every year, the proportion of accidents caused by fatigue driving is as high as 21%. Therefore, in our safe driving training, fatigue driving is the top priority. The root of preventing fatigue driving lies in people, and the key to the person’s ideological consideration is the key.

Aiming at the stubborn problem of fatigue driving, SAIC Hongyan’s “5G+L4” smart heavy trucks’ platoon driving effectively solved it. Queue driving is an important part of L4 automatic driving. We can simply understand it as: intelligent adaptive cruise.

The degree of intelligence lies in the fact that the vehicle can maintain the set distance between vehicles and drive in a queue. The vehicle in front accelerates and I accelerate, and the vehicle in front decelerates and slows down... With lane shift assist technology, when the vehicle is lane shifted, the assist function Automatic correction will be carried out in time, so that the vehicle always keeps in the specified lane and runs in file according to the set distance.

Fourth, L4 autonomous driving allows truck drivers to relax

The key reason why many professional drivers are called "old drivers" is their rich driving experience, lower accident rate and higher safety factor. Based on these factors, such drivers are always hired by the fleet. Sweet pastry".

What SAIC Hongyan’s “5G+L4” smart heavy truck has done is to collect and store the valuable experience of these old drivers, and use data technology to integrate into L4 autonomous driving applications, which is equivalent to establishing a wisdom for the vehicle Learn from the experience of “veteran drivers” to empower autonomous driving. With the help of Internet of Vehicles information and communication technology, it can realize the comprehensive network connection of in-car, car and people, car and car, car and road, car and cloud service platform technology.

In addition, SAIC Hongyan’s “5G+L4” smart heavy truck uses the original Jessie C6 high-roof cab, equipped with a 4-valve, turbocharged and inter-cooled clean energy LNG engine; the brake adopts EBS+EPB+ESC full-disc braking, The trailer is equipped with TEB; and the intelligent driving Al artificial intelligence +5G+V2X vehicle-linked communication system that can safely increase the density of the vehicle by 100%. This system can collect and analyze big data and realize independent upgrades. It is automatically controlled through the intelligent driving electronic control chassis The vehicle is moving.

Conclusion

Empower truck driving with 5G technology and replace old experience with big data. Through the various amazing performances of SAIC Hongyan’s “5G+L4” smart heavy trucks, we feel the magic of the rapid development of automotive technology. The often-spoken “the future is here” is really here! The industry is quietly changing and it will change the lives of truck drivers.

To be honest, due to the emergence of age "faults", the retirement of old drivers, and the inability to keep up with the number of new drivers, the current shortage of truck drivers has caused most of the fleets to face recruitment difficulties. After the outbreak of the global epidemic, with the growth of Internet shopping, the demand for freight will increase. But how can the already scarce shortage of truck drivers be filled? It is indeed a real problem before us.

Autonomous driving should not just replace truck drivers and their jobs, but should bring brand new solutions to these new needs. As Musk said in an interview: "I am definitely not trying to take away people's steering wheels. Autopilot may be 10 times safer than human drivers. It is relatively easy to have a driving license. Things, but under normal circumstances, people may cause accidents due to drunk driving, distracted driving, sending and receiving WeChat, SMS while driving, etc. These problems are completely absent from automatic driving."
