Description

technical field [0001] The invention belongs to the technical field of automobile test platforms, and in particular relates to a vehicle reliability test platform and a method of use thereof. Background technique [0002] In the early days, cars were only given short test drives after final assembly to check their quality. Some automobile manufacturers build special test road sections (including different road surfaces and ramps) near the factory area. In 1924, General Motors of the United States established a dedicated automobile proving ground in Milford. Subsequently, automobile companies in the United States and Europe successively built their own testing grounds. There are more than 60 test sites with an area of ​​100-3500 hectares in the world. In addition to testing the entire vehicle, major automobile factories and professional manufacturers also use indoor test benches to test the performance, efficiency and reliability of major components such as engines, carbur...

AI Technical Summary

Problems solved by technology

However, this kind of test is generally used for a single performance or durability test or a comprehensive test of a few related items. The driving state of the simulated car is relatively simple. Most of them just drive the car on the conveyor belt at a constant speed in the wind tunnel, and cannot simulate more complex states. , the comprehensive performance cannot be comprehensively assessed, and most of the test benches can only conduct experiments on a small number of designated models of cars, and the generalization is low
