On September 16, 2011, the launch conference of Yutong’s “Green Zone Anjie Driving Support System” was held at the Nikko Hotel New Century Beijing. Leaders of 33 bus companies from 31 provinces and cities in the country, relevant Yutong staff, and numerous media reporters All came to the conference site. At the meeting, Dr. Yu Zhizhan, a laboratory engineer of vehicle performance at the Yutong Bus Laboratory Center, gave a keynote speech titled “Discovering the Green Zone”. He vividly explained the technical principles and energy-saving functions of the Green Zone system to the guests present. Yu Tong, Vice President Manager Wang Wenbing announced the green zone listed model customer recruitment policy.

The Green Zone Anjie help drive system is another technological brand launched by Yutong following the engine thermal management system and vehicle cathodic electrophoresis. It is also another important achievement under Yutong's “Anji Festival Value System”. According to reports, the "green zone" is mainly aimed at the frequent shifting of the bus market and the background of driving operation with high fuel consumption, and has developed a pilot-assisted driving system designed to achieve the optimal fuel economy of the vehicle. In the product terminal, the green light is displayed in the energy-saving driving state, and is displayed as a yellow light or a red light when a shift is required, and is therefore named "green area".

The survey shows that many drivers have irrational driving habits, such as unreasonable use of gears in the driving process, improper shift timing, etc., especially after the engine entered the electronic control era, the driver did not understand the characteristics of electronically controlled engines, resulting in The vehicle consumes a lot of fuel during use. The Green Zone Angang driving support system is based on the development of the engine's electronic control system. It can intelligently analyze the driving operation process according to the engine operating point and vehicle driving status, prompting the driver to perform a reasonable driving operation, making the engine work economically. In a good area, the vehicle's optimal fuel economy can be achieved and the goal of fuel economy can be achieved.

In the actual operation, the green zone has three basic functions, such as the fuel-saving driving function mode, voice prompts, and fault diagnosis display, which can maximize the excavation of the existing electronic control system, vehicle and driver's section without changing the hardware conditions of the vehicle. Oil potential, with great practicality.

According to the organizers, an important goal of this conference is to recruit 10 model customers for the public transport market and conduct a three-month trial of the Green Zone safety driving system. The confirmed model customers can sign the "Green Zone Trial Agreement" with Yutong, select five cars with two lines to test the "green zone", track the driver's application status, and record the daily fuel consumption data of the trial vehicle in detail. After 3 months of use, companies that have confirmed that they are effective pay the “Green Zone” fee to Yutong at the selling price.

This practice of putting technical products into practical use proves its value. The practice of “try and decide whether to buy first” is not only an innovative marketing method, but also reflects Yutong’s confidence in its own products and its emphasis on customer interests and protection. . In this regard, Wang Wenbing, deputy general manager of Yutong Bus, said that Yutong Bus has always been customer-centric. The Green Zone Angang driving support system has been validated by our previous experiments to verify its effectiveness and reliability. We are confident that we will also be able to bring greater value to our customers through continuous efforts.

Yutong's confidence comes from strong technical strength and good test results. Yutong has the first postdoctoral workstation and the first national-level technical center in the domestic passenger car industry. It spends hundreds of millions of yuan each year on research and development. The Green Zone and Yutong’s other representative achievements are backed by strong technical support and experience. A wealth of pre-tests have proved that the fuel-saving effect is actually confirmed. The first is the verification of the prototype car in the factory, which adopts two types of passenger and bus vehicles, and conducts comparative tests under high-speed working conditions, national working conditions, and urban working conditions. From the test results, it can be seen that the comprehensive average fuel-saving rate of the green area is 11.62%; Under the condition of national roads and public traffic conditions, shifts are frequent. According to the shifting of the system, the driving fuel saving rate is high. Second, the use of the user under normal conditions of use of statistical verification, the first batch of public transport in Zhengzhou on the 26th, the five vehicles installed the system. Finally, through the analysis of the test results, it is proved that the vehicle's fuel saving effect of installing the green zone system is significant, reaching 3%-5%. At the same time, the test also found that whether the driver can follow the prompts, but also have a certain impact on fuel consumption.

Experts initially estimate that the current number of public buses on the domestic market is about 420,000, and the conversion of vehicles of different lengths can be referenced to 9 meters of public transport. The reference fuel consumption can be regarded as 29 litres/100 kilometers. The driving support system is calculated based on the fuel saving rate of 4% under normal operating conditions. The national bus market can save more than 480,000 liters of fuel per 100 kilometers.

Since the release of the Anji value system in April 2011, Yutong Bus has been able to continuously improve the value system of Anjie with practical actions. The release of the Green Zone Angang driving assistance system will further enrich the content of the Anjie value system and will also contribute to energy conservation and consumption reduction in the national transportation industry.
