The invention provides a vehicle crosswind stability test method, S1, installing test equipment, for providing crosswind for the test vehicle, and for collecting data information of the test vehicle; S2, setting a baseline on the test track, testing The vehicle runs straight along the reference line; S3. Set up the test area for the lateral position change of the vehicle, which is used to detect the lateral position change of the test vehicle when driving in the area; S4. Collect the test data of the vehicle in the crosswind area. The requirement of S3, otherwise it is invalid data, and the lateral offset is calculated by the calculation formula. The vehicle crosswind stability test method of the present invention can accurately and quantitatively measure the sensitivity of the automobile to the crosswind effect, and the test device used is simple to install, easy to use, and has a certain value for evaluating the handling stability and safety of the vehicle when driving at high speed. important meaning.
Description
technical field [0001] The invention belongs to the technical field of automobile testing, and in particular relates to a vehicle crosswind stability testing method. Background technique [0002] The dynamic behavior of a vehicle is an important component of active vehicle safety. During driving, the car, the driver and the surrounding environment form a unique closed-loop system. Due to the complexity of each element in this closed-loop system and the significant interaction between them, it is very difficult to evaluate the dynamic characteristics of the vehicle. Therefore, a complete and accurate picture of a car's performance must include a range of different types of tests. For example, in the process of driving a car, the movement of the car will be disturbed by the crosswind. According to relevant statistics, the direct economic loss caused by traffic accidents reaches 1 billion yuan each year, and a considerable proportion of these traffic accidents are caused by h...
