"

Ma Zheren, founder and CEO of Yuche Technology

Wei Bingwu, director of Shanghai SME Development Service Center, was invited to attend the meeting. He said that Hunche Technology is one of the key unicorn enterprises in Shanghai, and congratulated Hunche on his achievements in autonomous driving technology and products. The city service center will rely on the "Shanghai Enterprise Service Cloud" as the platform carrier, actively link resources, further do a good job in unicorn cultivation, and empower enterprises in the critical period of growth.

NOA, a winning truck, travels safely over 50 million kilometers, and the commercial value of autonomous driving has been verified on a large scale.

Mache Technology has cooperated with more than 100 shippers and carrier fleets to carry out normalized intelligent heavy truck operation services, with a commercial operation mileage of over 50 million kilometers, covering more than 340 trunk high-speed operation lines in seven core economic zones across the country, with a cumulative shipment of nearly 50,000 times, all of which were completed by a single driver. In the normal commercial operation of intelligent driving heavy trucks for more than 600 days, the automatic driving mileage accounts for more than 90%, which continuously creates significant value for logistics customers in terms of safety, manpower saving, labor saving and fuel saving.

Ayushun, Executive Vice President of Mache Technology

• Security:On Science and Technology Day, Pacific Insurance and Hunche Technology jointly released the industry’s first complete annual smart driving heavy truck insurance data report, which compared the safety performance and accident data of smart driving heavy trucks and traditional heavy trucks in detail. Compared with manual driving, intelligent driving can be reduced by more than 75% in core indicators such as pre-collision warning, lane departure warning and sudden deceleration.
• Save people:NOA, a winning truck, changes the driver from the previous pure manual driving mode to a simple and relaxed safety officer mode, which greatly reduces the work intensity and driving fatigue. Through safe and sustainable single driving, the ratio of people to vehicles has been significantly reduced in various trunk logistics subdivision scenarios such as express delivery, contract logistics, LTL and vehicle-specific lines, and the labor cost can be saved by 20%~50%.
• Save effort:Hunche Technology and Beijing Institute of Technology’s aerospace human factors engineering team introduced aerospace human factors research into truck autonomous driving. After 134 trips of transportation tasks and nearly 120,000 kilometers of drivers’ physical fatigue and psychological fatigue index tests, the results show that compared with traditional truck drivers, the physical fatigue of intelligent truck drivers who use NOA, a well-won truck, decreases by about 35%, and the psychological fatigue decreases by about 11%. This test provides industry norms and standards for human factors research of intelligent truck driving, and fills the gap in the industry. The two sides pioneered a research method for testing the physiological and psychological fatigue indicators of smart truck drivers. The signals of physiological and psychological indicators such as EMG and ECG were collected through wearable skin and ECG modules, and a multi-modal biomathematics model of driving fatigue based on three dimensions of physical load, alertness and cognitive load was constructed.
• Fuel saving:According to NOA commercial operation data of Hunche truck, the fuel saving performance of Hunche intelligent heavy truck is better than the customer’s fuel consumption assessment standard in the core freight flow direction of East China, South China, North China and Central China, and the average fuel saving per 100 kilometers can reach 1-3 liters, which is 3%-7% compared with excellent human drivers. Among them, 30% of the normal operation lines can achieve 7%-10% fuel consumption reduction.

NOA, a winning truck, leads the level of truck automatic driving technology. Its national expressway availability rate is 100%, and the commercial operation coverage rate of expressways has reached 70%. It also overcomes the problems of continuous bends, long downhill, continuous tunnels and lack of RTK positioning signals, and realizes safe and reliable traffic on complex roads. The original fuel-saving algorithm (FEAD) of Hunche Technology has completely surpassed the predictive cruise algorithm (PCC), and achieved lateral control, traffic flow response, global speed planning, and more accurate calculation of load and rolling resistance coefficient, which significantly improved the fuel-saving effect. Aiming at the limitation of heavy truck data transmission, NOA creatively realized the enhanced shadow mode of combining end and cloud, directly purified driving data at the vehicle end, uploaded high-quality data fragments, and formed 550,000 high-value scenes, which were simulated and trained in the cloud data lake. The version update cycle only took 14 days.

Three core technologies in the new stage of NOA for winning trucks

Dr. Yang Ruigang, CTO of Hunche Technology, said that starting from the 50 million km milestone, the automatic driving technology of Hunche truck will accelerate the expansion of the capability boundary, especially: better national road performance, surpassing the higher cognition and smarter decision-making of old drivers, and supporting the OEM to realize more and faster vehicle adaptation. On the Science and Technology Day, Winch Technology comprehensively interpreted the three core technologies in the new stage of NOA of Winch Truck:

• End-to-end network with security fenceEnd-to-end network can significantly improve the performance of autonomous driving, which is a general trend in the industry. However, the traditional end-to-end network is difficult to be applied to real scenes on a large scale because of its lack of interpretability and reliability and lack of security guarantee. Qiche innovatively put forward the "end-to-end network with security fence", which decomposes the traditional end-to-end network into several differentiable sub-networks, establishes an interpretable end-to-end network, and constructs a security fence to restrain it, so as to maximize the use of the intelligence of the end-to-end network and ensure the safety of autonomous driving. At the same time, the Occupancy Grid Map-OGM is used to represent in three-dimensional space, so as to realize the effective recognition of special-shaped objects and complex scenes. In addition, in view of the challenge of heavy truck’s long sensing distance to OGM’s computing power and memory consumption, we have developed an efficient OGM technology, which adopts adaptive granularity and sparse algorithm to reduce computing power consumption by 55% and memory consumption by 70%, and provide users with higher cost performance.

Dr. Yang Ruigang, Won Che Technology

• Won the super driver.NOA, a winning truck, has approached the outstanding drivers of human beings in behavior at present, and even surpassed the outstanding drivers in several key dimensions such as fuel consumption. In order to continuously optimize the NOA performance of Won-Che truck, and achieve a comprehensive transcendence over the old human drivers in driving behavior, Win-Che Technology began to build a Win-Che super driver by combining the massive data obtained from commercial operation and the highly intelligent LLM model. Firstly, the driving behavior and scene data are atomized and subdivided in more than 300 dimensions, such as weather, road material, lighting, road structure, traffic flow, vehicle type and load, and naturally linguistized; At the same time, combining manual labeling and automatic labeling to form positive and negative driving behavior atomic sets, LLM model is fine-tuned, and a general intelligent big model TruckGPT focusing on truck automatic driving is customized. In view of the long tail problem that is difficult to deal with in the contemporary autonomous driving technology, the general intelligence of TruckGPT is used to optimize driving behavior, to build a super driver, and to strive to surpass the old driver in terms of fuel consumption, safety and driving comfort.

• Ma che zhi Jia platform
• In terms of hardware, Manche Technology has designed a new generation of ADCU computing platform for truck intelligent driving system. The new platform provides powerful AI and CPU computing power to meet the needs of trucks for remote sensing and fuel-saving algorithms. In view of the challenge of closed-loop data caused by long-distance weak network and changeable working conditions of trucks, the new platform provides large-capacity storage capacity and data management system, and ensures the success rate of high-value data return to 99.9% through technologies such as data compression and intelligent breakpoint continuous transmission. The new ADCU has also reached the functional safety level of ASIL-B and the information safety level of ISO 21434 certification, which fully meets the harsh operation and maintenance environment of trucks.
• On the platform software level: Penche Technology has developed the core functions of vehicle hardware management, basic functions of system software, functional safety and information safety management, following the design concepts of integrity, universality and standardization. The platform software includes software development packages such as Vehicle Abstraction (VAL), Sensor Abstraction (SAL) and automatic code generation, which greatly improves the research and development efficiency and reduces the adaptation time of NOA, a brand-new truck, to 9-12 months.
• In the aspect of truck EEA architecture: Hunche Nebula architecture has released a new generation of functions, providing more efficient and flexible solutions for OEM and Tier-1 partners. The new generation scheme uses the communication architecture of Gigabit Ethernet, which effectively solves the bandwidth bottleneck of traditional CAN/LIN bus. At the same time, the new generation of Hunche Nebula architecture also provides IASP standardized service library to meet the needs of rapid application of new models and high-performance transformation of old models at controllable cost. The overall scheme realizes full modular software and hardware decoupling, can be split and delivered in multiple dimensions, adapts to the differentiated electronic and electrical architecture of multiple OEMs, and efficiently supports the upgrade of truck EEA architecture.

Mache Technology signed purchase and strategic cooperation agreements with Shentong Express, Zhongtong Express and Debon Express.

At the site of this Science and Technology Day, Science and Technology Co., Ltd., Dongfeng Commercial Vehicle and Shentong Express signed the first batch of 500 smart heavy trucks procurement and strategic cooperation agreements, China Heavy Duty Truck and Zhongtong Express signed the first batch of 200 smart heavy trucks procurement and strategic cooperation agreements, and Debon Express signed the smart heavy trucks strategic cooperation agreement.

Original title: The movie Hot Search: Behind the "hot" is the "cold" data.

"Hot Search" is a very brave film, revealing some realities that were unknown, dare not say and no one said before. A cup of exquisite coffee, a fresh life, a bustling high-rise building and a cold rooftop, this contrast is too stinging. Moreover, it is rare for the director to give the audience a position of God’s perspective, that is, to jump out of the plane surrounded by public opinion or other people’s manipulation and to see the overall fermentation and trend of an event. It makes people feel wonderful and have some thoughts at the same time. Once upon a time, did I just be a member of that team?

The film tells the story that after Chen Miao, the editor-in-chief of the media, published an explosive article, he unexpectedly received help from the parties and involved a series of unexpected events. Chen Miao, the editor-in-chief of the media, penetrated the traffic password and created an explosive article to rush to the hot search, but indirectly boosted the female student of the "bully" to jump off the building. At this time, Chen Miao accidentally discovered the help information sent by a female student and involved a sexual assault case. He Yan, a partner of Chen Miao, and Peng Yue, a wealthy investor, were involved one after another. Public opinion has turned many times, what kind of interest chain is hidden behind the incident, and a public opinion war for the weak has started …

The film begins with cyber violence and reveals the story behind the frequent cyber violence in recent years. In this era when the media broke out, the truth of the matter is reversed every minute. The illusion of public opinion and the hot search list are behind the bloody and explicit truth, which makes people wonder how to choose justice in the Internet age. The network is rooted in life and has a far-reaching impact on life, even amplifying the dribs and drabs of life. Now the network world can no longer be described by virtual world, it is an enlarged version of the real world, and it has a layer of gauze more than the real world. The starting point of the film is very good, which lies in reminding, awakening and encouraging the conscience and goodwill of the society.

The whole film seems to focus on a story line of justice, using the shell of the current self-media and nesting it with an introduction of campus violence to show the dimension of "realism", but in fact, the film cleverly bypasses all issues that may cause stinging pain. Rather than focusing on the boundary of speech in the media era, this film focuses on the rabble to see how public opinion is induced and used again and again. All people give up thinking and become minions of traffic and topics under the guidance of the media, but this concern does not seem to be the main theme of the film, and the audience’s sense of justice is satisfied with the actions of the protagonist.

In the era of network information, there will be all kinds of information around us, and it is difficult to tell whether it is true or not, as well as active and passive cyber violence with guns and sticks in the information. As Deng, a student of Hunan Qifa Culture Media Co., Ltd., wrote in his commentary, this film is a realistic film that reflects cyber violence well. Moreover, it is said that it is based on a real-life event. If it is true, I can only say that the director dares to shoot. I really can’t imagine how to face it if I am in such a thing, but it also reminds us to express our views cautiously and restrained before facing an event that we don’t know the truth, instead of being mindless. Resist cyber violence and purify the network environment, starting from you and me.

The film focuses on the ethics of media and news reports and the ethics of media people. In today’s era, it is difficult to tell how much public opinion is being manipulated on the Internet, and how much traffic is behind whether the capital is pushing whether the traffic is the highest or the truth is the highest, whether the content is king or the capital is king, in repeated reversals and games. The movie plot seems to map every hot search that really happens on the Internet today. The hot search is not the hot search for defending justice, but the hot search for cyber violence, profit-seeking capital and carnival of the mob. Behind the hot search are actually cold data, indifferent individuals and neglected victims.

The director explained in a simple way how the media now use templated methods to manipulate public opinion to chase hot spots, and how ironic it is to quickly incite the mob’s emotions with just some eye-catching titles without moral bottom line. Isn’t this the case in the fast food era? Emotional venting is far more concerned than the truth. However, many people are eager for gold, and the bones are ruined. Words have no blade, killing is invisible! Therefore, together with the copywriters of Hunan Enterprise Culture, we should be a persistent self-media person, not seeking to be a Buddha who saves people, but seeking not to be a broker of public opinion, because the manipulator will also become a victim. Goodwill is more important than hot search. Truth or illusion? Holding the sword of justice has been secretly used. Before the next comment on social events, we can let the bullets fly a little longer.

Zhao Junzhe headed back to the middle in the restricted area, and Li Jinyu volleyed the goal with his right foot. In the 29th minute, Roman Abramovich succeeded in offside and passed Li Leilei. Rooney received the ball and deliberately stayed in front of the door for a period of time before pushing the far corner. The score became 4-3. Then the northern team immediately returned the favor, and the curve wave broke through on the right and passed to the door, and the goalkeeper struggled to save the ball.

　　The backward northern team stepped up their offensive. In the 34th minute, Du Zhenyu stopped the ball in front of the restricted area, and volley and the goalkeeper punched the ball. This shot was very wonderful. Two minutes later, the Southern team expanded its lead, and Wang Yun passed the ball to Li Yan at the bottom line on the right. The latter’s heavy bombardment caused Li Leilei to save the ball and Vicente easily made up the shot, and the score was rewritten to 5-3. In the 41st minute, the southern team organized an attack in the frontcourt, and Li Yan’s shot in front of the restricted area was higher than the crossbar. In the 43rd minute, the northern team got a chance on the left, and Zhikov made a high-quality cross to the goal. Unfortunately, Qu Bo’s header was slightly higher than the crossbar.

　　In the 50 th minute, the southern team made a long pass in the backcourt and Rooney quickly inserted it. The goalkeeper took the lead in clearing the ball. In the 54th minute, the northern team pulled back a point, and Elvis left the left unguarded, easily leveled the ball to the middle, and Diego succeeded in shooting from the far corner, and the score was rewritten to 5-4. Later, the southern team returned the favor. Wang Yun passed the ball to the middle of the road on the right. Rooney’s powerful long-range shot missed the goal, followed by Zhang Ye’s loss of the ball in the backcourt. Elvis’s shot in front of the restricted area caused the goalkeeper to get rid of the ball, but the second shot quickly hugged it. In the 57th minute, the southern team played a series of subtle cooperation. Rooney stopped the ball in the back of the chest and volleyed across the door. Wang Yun passed the ball again in the restricted area, and Yang Lin, who was inserted later, pushed the goal and the score became 6-4. Then the northern team also scored a goal immediately. Elvis successfully shot the far corner on the left side of the restricted area, and the score became 6-5. In the 63rd minute, Rooney put on a solo performance, dribbling the ball from the left side to the restricted area and hitting the side net.

　　As the game went on, the scene was a little dull. In the 68th minute, Elvis passed in front of the restricted area, and then he shot with his long foot. The ball was saved by the goalkeeper, and Dong Wang’s supplementary shot hit the defender out of the bottom line. Then the northern team seized the opportunity. Tao Wei faced the defense in front of the restricted area and dodged the empty shot. The ball entered the door against the far post, and the score became 6-6. In the 74th minute, the northern team made a quick counterattack. Wang Yun made a wonderful pass from the front of the restricted area to the back point, and Yang Lin’s header was first cleared. In the 78th minute, the Southern team expanded the score again. Sun Xiang made an assist from the left and made a cross to the frontcourt. Rooney grabbed a header in front of the door and the score became 7-6. Then Rooney once again showed his football talent, and an imaginative shot almost broke the door again. In the 82nd minute, the Northern Team equalized the score, and Tao Wei returned to the middle from the left. Zhao Junzhe took the ball with two steps and shot with his right foot. The ball crossed the goalkeeper and fell into the net, and the score became 7-7.
