Yiche's original and most elementary "automatic driving" appeared in the factory half a century ago - presumably everyone has seen a kind of automatically running AGV trolley shaped like a tray in the factory, generating electromagnetic frequencies through wires buried in the ground, and guiding the vehicle through a magnetic field. However, expanding to the concept of automatic driving, unmanned transportation may be the "forerunner" of automatic driving.
There are many reasons why the commercial logistics field often has the technology of automatic driving or related products, for many reasons, such as: high labor costs (for example, the annual salary of heavy truck drivers often exceeds 200,000 yuan), long-distance transportation consumes drivers and requires high requirements, fuel costs are high, carbon emission pressure increases sharply, and so on.
On December 26th, as an advanced commercial vehicle intelligent driving science and technology innovation company in China, Shanghai Youdao Zhitu Technology Co., Ltd. showed us its L3 &L4 level intelligent heavy truck products in the Shanghai Lingang Intelligent Connected Vehicle Comprehensive Test Demonstration Zone.
It is reported that youdao Zhitu intelligent heavy-duty truck products are complementary to each other through data drive and algorithm iteration, and have achieved a real scene automatic driving test mileage of more than 2 million kilometers, and a high-speed scene quasi-commercial operation of 60,000 + TEU (TEU is a standard container). With the help of China Mobile's 5G technology, high-precision map Beidou positioning, and Honghu intelligent driving platform, the current Youdao Zhitu L4 smart heavy truck can achieve many industry-leading technical indicators: such as 5 car formation driving, fleet spacing is less than 16m, automatic parking time is less than 70s, compared with the number of drivers can also reduce the market by more than 30%, such as vehicle accurate parking accuracy is less than 3cm, these technical indicators allow Youdao Zhitu smart heavy truck products can effectively improve the transportation efficiency of such scenarios as ports and industrial parks. At the same time, driving in formation can also reduce the energy consumption of enterprises.
Subsequently, we also entered the Youdao Zhitu smart heavy truck and actually felt the automatic driving ability of this heavy truck product. The open test section is the Donghai Bridge - Yangshan Port Phase IV Wharf, the total length is about 36km, and the test time is in the afternoon, the working conditions of the entire section are more complicated, not only containing a large number of other manually driven heavy-duty truck vehicles, but also many social private vehicles, which is still quite severe for the test of Youdao Zhitu Smart Heavy Truck.
However, although the overall experience is different from the passenger car products in terms of comfort, but the safe driving logic, formation form, short overtaking, etc. have been very mature, and the engineers on the car communicate, at present, this heavy truck product can be realized 5 cars only the head and tail of the car need to be equipped with safety personnel (but the current regulations have not yet been allowed, so this heavy truck fleet each car has a safety officer), the whole process of automatic driving, accurate parking to the port loading and unloading point, etc., through the vehicle overhead 32-line lidar, 16-line lidar on both sides, Multiple millimeter-wave radars and the latest vehicle-grade 1000tps+ computing chip can now fully cope with this relatively complex road condition of autonomous driving.
In the product part, in addition to experiencing conventional smart heavy-duty truck products this time, we also saw the AIV vehicle that Youdao Zhitu has piloted at the Gaoqiao Phase IV terminal outside Shanghai, and this pure electric, no cab intelligent vehicle also ranks in the domestic leading position in the overall performance indicators: pure electric mileage reaches 110km, continuous operation for 12 hours, regardless of the front and tail of the car, and four-wheel independent steering, which can be driven laterally and obliquely like a crab, and even turn around in place ... These characteristics also determine that the AIV model is not only efficient in operation, but also does not require a driver and does not require refueling, which can greatly reduce operating costs.
The body is surrounded by sensors, and it does not require a major renovation of the venue like the AGV model at the beginning of the article. As of this year, Youdao Zhitu has invested 8 AIV models in the Fourth Phase of Shanghai Outer Gaoqiao Wharf to carry out real production operation test operations, completed the transshipment of 1,000 standard containers within 3 months, will add 30 AIV models next year, and is expected to complete the transshipment of 100,000 standard containers next year.
Full text summary: The development of the concept of automatic driving has also had more than ten ideas so far, in the field of passenger cars we often mention the driver assistance system, although the development of hardware and software has been very advanced, but for the completely open road urban road conditions coping is still quite risky.
However, in the field of commercial vehicles with fixed paths and relatively closed operating scenarios, we can see that companies such as Youdao Zhitu have come up with sufficiently competitive, and full of phenomena and practicality of autonomous driving products, after testing, trial operation, large-scale commercial operations and other processes, it may be that in the near future, we can see a large number of such vehicles on the highway, and it may not be very far from the automatic driving of our private cars.
