On August 26th, the Jiefang Powertrain Business Unit held the world's first Jiefang Smart Power Domain product launch event in Wuxi, Jiangsu Province, with the theme of "Smart Leading New Journey to See the Future".
Guests attending this event include Mr. Huang Zhen, member of the Standing Committee of the National Committee of the Chinese People's Political Consultative Conference and academician of the CAE Member, Mr. Zhou Wendong, deputy mayor of Wuxi Municipal People's Government, Mr. Hu Hanjie, assistant general manager of FAW, chairman and party secretary of FAW Liberation, Mr. Xing Min, executive vice president and secretary-general of China Internal Combustion Engine Industry Association, Mr. Zhou Zichuan, deputy secretary and head of Yangxi District, Wuxi, deputy secretary of the party committee of FAW Liberation Mr. Zhang Guohua, Chairman of the Trade Union, Mr. Li Sheng, Deputy General Manager of FAW Jiefang and General Manager and Party Secretary of Qingdao Automotive Business Unit, Mr. Qian Hengrong, Assistant General Manager of FAW Jiefang and Party Secretary of the Powertrain Business Unit, Mr. Ni Mouchun, Deputy Party Secretary and General Manager of the Powertrain Business Unit of FAW Jiefang, as well as representatives of partners and dealers
In November 2022, FAW Jiefang underwent a quiet transformation of its powertrain business, integrating the original engine and transmission business units into the powertrain business unit. That is to say, the Jiefang Powertrain Business Unit covers the business of engines, transmissions, and axles, and is truly a powertrain. And the biggest difference between it and the power division of other main engine manufacturers is that the Jiefang powertrain division is not targeting the power chain, but the power domain.
There are four major solution platforms for liberating the intelligent power domain: G, H, E, and F. Among them, G represents the G power domain consisting of a diesel engine, an AMT transmission, and a drive axle. The H power domain represents the hybrid H power domain with green low-carbon engine+battery, hybrid transmission drive axle, and domain control as the core. The E power domain is a pure electric zero carbon power domain solution with batteries, integrated electric drive bridges, and domain controllers as the core, and finally, the gas electric zero carbon F power domain with gas electric engines, batteries, integrated electric drive bridges, and domain controllers as the core.
What are the advantages of the power domain? It is understood that the traditional chassis bridge power chain adopts distributed independent control, which cannot be coordinated and integrated, making it difficult to fully leverage the advantages of the system; In addition, the traditional chassis bridge power chain lacks a smart brain, which cannot ensure that the vehicle always operates in the optimal operating range, and the performance gradually decreases during its lifecycle.
The GD300-3.0 Jiefang Intelligent Power Domain released this time adopts an integrated integration architecture, with four major platforms: powertrain, controller, software, and cloud. It adopts a high-performance collaborative control architecture to replace the original distributed control architecture, which is more centralized and efficient; The software platform with intelligence, collaborative control, adaptive technology as its core forms real-time interaction with the independent cloud big data platform, achieving functions such as optimal collaboration, intelligent diagnosis and predictive maintenance. At the same time, the high degree of collaboration between software and hardware in design supports Jiefang to continuously provide users with green intelligent power solutions with high intelligence, high reliability, and low TCO in the product and ecological fields.
In addition, this power domain also has six major intelligent advantages, including intelligent efficiency, intelligent control, intelligent power, intelligent customization, intelligent monitoring, and intelligent services.
For example, intelligent and efficient: adopting the new generation "first" dual overhead high-efficiency CA6DV1 engine, matched with the highest efficiency of 99.8% of the 12TA300 direct integrated AMT, paired with a 440 small ratio through bridge, the highest efficiency is 99%. The new autonomous powertrain is strongly combined to create a green and intelligent power domain. The GD300-3.0 power domain has a comprehensive efficiency of>49%, setting a new benchmark for extreme fuel saving, with a comprehensive fuel saving of over 3%, and saving users over 10000 yuan in fuel costs annually.
There are five specific advantages:
Intelligent control: matching and integrating intelligent control systems to achieve scene coordination, global planning, temperature pre control, intra domain collaboration, and digital twin functions; We promise absolute safety and efficient operation to provide users with the best driving experience and fuel efficiency.
Intelligent power: The CA6DV1 engine leads the industry in transient response by 10%, with a maximum torque of 3000N · m, reaching the industry's 15L product level in cross level competition. It has abundant low-speed torque reserves and is suitable for high-end logistics scenarios. It can be matched with a direct transmission and a small ratio rear axle to reduce engine speed while ensuring surging power, and the Downspeed system saves fuel; For plateau scenarios, the engine plateau power compensation technology package and the box bridge plateau intelligent control technology package are used. The 3000 meter plateau power is not limited to torque, and the 4000 meter power performance is more than 10% higher than the industry. The climbing slope is ahead of competitors by 10%, and driving on plateau mountain roads is effortless.
Intelligent customization: Based on the Jiefang Data Processing Center, real-time data reception, storage, calculation, and analysis in the power domain are carried out. Combined with driver driving behavior analysis, Jiefang TSP pushes feedback to users for data upgrade decisions, achieving the goal of a more fuel-efficient, stronger, and more reliable power chain.
Intelligent monitoring: Through the integration of design, process, and manufacturing technology, as well as the integrated lifespan design of machines, boxes, and bridges, the full cycle performance function of 2 million kilometers does not decay, which is 30% higher than the previous generation of models on sale. The reliability level is the first in China and world-class; Intelligent robustness closed-loop, achieving self diagnosis, adaptation, and self repair of performance throughout the entire lifecycle, and intelligent assurance of self sustained optimization throughout the entire lifecycle.
Intelligent services: Based on T-box and Jiefang Cloud, and big data analysis platforms, we build a smart ecosystem in the Jiefang Power Domain. Through more than 100 intelligent algorithms, we can perceive transportation and environmental factors in real-time, intelligently identify user needs in real-time, and iterate optimal parameter solutions in a timely manner to achieve dual reduction in fuel consumption and emissions, dual improvement in smoothness and durability, and the application of intelligent algorithms such as predictive maintenance and parameterized diagnosis, Real time calculation and diagnosis based on vehicle status, staying at home, real-time control of vehicle status, and providing predictive maintenance services. Thanks to the improvement of algorithm accuracy and the increase in the number of intelligent algorithms, the average maintenance efficiency has increased by 30%. Maintenance reminders and remote maintenance guidance have achieved zero unplanned downtime.
The release of the world's first Liberation Smart Power Domain product means that the Liberation Power Assembly Division can provide customers with more comprehensive and efficient power solutions to meet the needs of different application scenarios. At the same time, it further consolidated Jiefang's strength and position in the field of automotive power, demonstrating Jiefang's keen insight into technological innovation and market demand.
