| description | The invention belongs to the field of car tire mechanical property data processing, and particularly relates to a method for carrying out partition fitting on slip rate test data of tire longitudinal force under transient composite working conditions, intelligent equipment and a computer readable carrier medium. The slip rate measurement range is divided into seven areas, cubic polynomial fitting is carried out on test data of the longitudinal force of each interval about the slip rate, and a function value and a first derivative value at each node are restrained to be equal. Through partition fitting, the test data of the loading section and the unloading section can be subjected to high-precision fitting to form a smooth curve, and the smooth curve is used for calculating the characteristic value of the tire, performing benchmarking analysis or identifying a tire model. The invention has the characteristics of high accuracy, good repeatability and high efficiency.
