At the beginning of June, the college entrance examination period, twelve years of studying in the cold window, between morning and evening. If you want to become a dragon, you must first leap to Longmen. Unlike Guanghan University, the truck “entrance†is only successful and must not fail. Unable to pass the first round of "entrance" truck, can only stay in the factory.
The "Language" of the truck entrance exam

For students, language is the foundation and foundation for everything. For trucks, it is the inspection reports, regulatory documents, and certificates for all vehicles and all parts and components.
These documents represent the design parameters, experimental results, and review and certification parameters of trucks and components. Only these written parameter files can ensure that the entire truck "college entrance examination" is carried out in an orderly manner. At the same time, it is possible to store the complete set of design parameters of the entire vehicle, and to prepare a comprehensive written preparation for the "college entrance examination". The preparation, verification and sorting of these documents are the “language†subjects of trucks. Whether the documents are complete and compliant determines whether the “Language†subject passes.
The "Mathematics" of Truck Entrance Examination
For students, mathematics represents logic and reason. It is to verify the degree of thinking and logic of students. In trucks, there are three aspects: whether the components of the truck are matched, whether the vehicle control system is reasonable, and whether the vehicle can be operated in an orderly manner.
Parts matching is tested in three steps. First: Bench experiment, bench test can verify whether the performance of parts and components is qualified, and record parameters at the same time. Secondly, the parameters are checked and matched, the parameters of the parts recorded before are matched, and the parameters are checked in the process. Third: match the experiment and verify whether the parts match by vehicle test.
The vehicle control system is mainly completed by the ECU (Central Control System), and the full control of the entire vehicle is achieved through the central control. Whether the operation of the entire vehicle system can be coordinated in a reasonable and orderly manner is the sole criterion for the central control inspection.
The orderly operation is verified by the road test of the vehicle. The road test refers to the on-the-road experiment conducted by the prototype vehicle, and the verified mileage is not less than 100,000 kilometers. Through a large number of intensified road experiments, reliable and good truck operation can be guaranteed.

Truck Entrance “Englishâ€
For students, English is a social language. It is a tool that is adaptable to the environment. In trucks, it is the ability to adapt to the environment.
The adaptability of trucks to the environment is mainly environmental experiments under road tests. Environmental experiments are mainly divided into several categories. In spring, they go to the south to conduct “waterproof experiments.†In the summer, they go to Hainan to conduct “high temperature experimentsâ€; in the fall, they go to Xinjiang to carry out “dust experimentsâ€; in the winter, they go to Heilongjiang to carry out “low temperature experimentsâ€. Only through these experiments, the truck "foreign language" subject passed.

Trucking College Entrance Examination
Yu Xuezi, a professional subject is a reflection of the specialization of the students' profession; in the truck, it is the inspection of the professional competence of the truck.
The functions of trucks are mainly cargo, transportation, logistics and so on. Therefore, trucks need to carry out load tests, full load/empty stabilization experiments.
The load test is to determine whether the truck has reached the design standard through actual cargo loading. At the same time, the experimental load should be higher than the designed load, and it should be used to bear the additional force when the wheel runs.
The full-load/no-load operation stability test verifies the stability of the road through two kinds of road experiments, mainly including the bendability of the snake-like experiment and the adaptability of different road conditions.
Only through the above subjects, the truck can complete mass production on the first round of the “college entrance examinationâ€, and the examination will take about one year. Because this is a national hard exam, this first round of “college entrance examination†has also become the “national exam†for trucks.
