Problems solved by technology

[0004] For the test method using the established working conditions, it usually only targets a single traffic environment with obvious characteristics, so it is difficult to provide comprehensive and real tested working conditions, and cannot meet the testing requirements of the global energy management strategy for the entire travel chain; For the test method using virtual scenes to obtain simulated driving conditions, it is necessary to establish a large number of road scenes and traffic participants in the environment, and at the same time to establish an accurate driver model, so the operation is complicated and the cost is too high in the actual application process Meet a wide range of testing needs
