The "three highs" test of the Howo trucks is to collect test data in the field test under the extreme environment of "high temperature, high cold and high altitude". "Three High" test team is a test team affiliated to Sinotruk Howo Co., Ltd. It was established in 2006 and has organized more than 30 "three high" tests, covering medium, heavy, light, There are more than 200 models from national III to national VI, with more than 400 participants.

They are always on the road to Turpan, on the road to the Qinghai-Tibet Plateau, and on the road to the extreme cold in the world. They go to find the hottest place in the midsummer season to accept the "baking" test, and leave their familiar and comfortable hometown to go to the barren and hypoxic plateau. In winter, they go to the land where dripping water turns into ice. They are dubbed by the industry as anti-season "migratory birds", and they write extraordinary youth stories during the experimental itinerary.

Every year from July to August, the average temperature in Turpan, Xinjiang is as high as about 45℃. The test members are not afraid or backward, and repeatedly carry out tests including engine flameout protection and engine matching test, adjusting measures to local conditions and innovating new control strategies to improve the performance of the engine thermal area.

Climbing from 1700 meters to 5200 meters, Golmud and other plateau areas are all over the footsteps of the test team members, they race against time, pursue the extreme, complete a series of engine, key parts and vehicle supercharger protection, carbon loading performance testing and calibration.

In Yakeshi, Inner Mongolia, and Mohe, the northernmost part of China, the outdoor temperature is nearly -40℃, and the cold start test is rushed to be carried out when the temperature is the lowest. When the temperature dropped by one degree, what they saw on their faces was not pain, but the joy of starting the engine successfully again after countless innovative and bold attempts.

The more extreme the environment, the more precious it is to the experimenter. The test team has not only the world's advanced commercial vehicle technology, but also the spirit of perseverance and tenacious struggle. In the rich and extreme weather, the test team gives full play to the team's advantages, continuously innovates, and obtains more test data to make the vehicle performing more stringent calibration procedures will result in more reliable products. The team members of the experiment actively exerted their enthusiasm for innovation to create a better ecosystem of scientific and technological innovation teams, thereby driving a wider range of scientific researchers to join the ranks of innovation and achieve new breakthroughs.

The team proposed a research on Howo truck adaptability based on the intersection of environmental engineering and reliability engineering. Product reliability and environmental adaptability belong to the quality characteristics of enterprise products, and it is necessary to cover and collect all operating scene data of actual user vehicles. Team according to the vehicle operation to different working conditions, different load conditions, covering four seasons, different high temperature, high altitude, alpine limit environment and its superposition, even low speed queue through kunlun mountain checkpoint conditions in fine measurement, through a lot of test verification and data accumulation, realize "car brain" ECU accurate control DPF active regeneration trigger time, effectively improve the vehicle dynamics, safety and fuel economy.

The establishment of the database based on vehicle extreme environment engineering and reliability engineering can be accepted and used by reliability engineering, which improves the ability of enterprise products to withstand extreme environments, ensures the validity of simulation analysis and calculation results, and improves the national six The performance of the vehicle in actual operation, such as durability, economy, environmental protection, etc., reflects the systematic, rational and scientific nature of the three-high test of the Howo truck.
