Tire longitudinal slip property measuring and data processing method and device, and computer readable carrier medium

The invention belongs to the field of lateral deviation and longitudinal slip composite slip mechanical property testing and dynamic modeling of car tires, and particularly relates to a tire longitudinal slip property measuring and data processing method and device and a computer readable carrier medium. According to the invention, the longitudinal slip rate measurement range is divided into a linear region, a nonlinear region under a small slip condition and a nonlinear region under a large slip condition. Through independent measurement of a linear region, the influence caused by tire tread abrasion and friction heat generation is eliminated; according to non-linear region measurement, the test temperature rise of the tire can be controlled within a reasonable range by adjusting the slip rate loading rate and cooperating with a standing cooling mode. According to the tire longitudinal slip characteristic data measured based on a partition measurement mode, the influence of heat generated by friction on a lo
