In order to analyze the difference between the high-temperature environment bench test and the real vehicle test results of high-temperature adaptability in the high-temperature verification of automobile interior and exterior trims, the high-temperature environment bench test and real vehicle environment test are carried out for passenger vehicle and SUV, and the differences are analyzed from the aspects of temperature, irradiance and wind speed. The results show that the main differences exist in irradiance, and it is proposed to install arc-shaped lamp support in the environment chamber and apply irradiance to the sides to reduce the differences, and thus enhance correctness of bench test.
