Problems solved by technology

To sum up, the actual vehicle field test requires the enterprise to invest a lot of manpower, material resources, financial resources and other resources, which will lead to a lot of time spent on the evaluation and adjustment of the prototype vehicle, which is not conducive to the enterprise to reduce the development cost and shorten the development cycle
[0005] Current problems: 1. Automobile test data is usually not processed at the test site. Due to the influence of driver’s subjective factors, there must be invalid test data in the test. If the invalid test data is found and eliminated in the later data processing, the existing valid test data The data is insufficient to support comprehensive analysis and evaluation of vehicle performance, and new field tests are required
Therefore, the entire test process wasted a lot of manpower, material and financial resources, prolonging the development cycle of
