Abstract: The identification and control of tire slip angle is the key technology of vehicle stability control, and identification and estimation of tire slip angle based on tire grounding characteristics is a new method. An intelligent tire development platform with multi-sensors was constructed and the tire cornering characteristics based on ground signal were analyzed by cornering test. Firstly, the function and design requirements of the intelligent tire development platform were clarified, and then the system architecture and hardware selection were built. The tire sensors include three tri-axial accelerometers and three piezoelectric film sensors. Secondly, the special rim assembly and the data acquisition device based on NI cRIO were developed. The software was developed and realized based on LabVIEW for multi-channel data synchronization and large data flow control. Finally, the tire cornering test was carried out on the Flat Trac platform. Through the analysis of the sensor signal, When the slip angle reached ±3°, the accelerometer (range 500g) had an over-range phenomenon, and the signal frequency is concentrate in 500-1 000 Hz. The signal of the accelerometer in the center plane of the tire is not sensitive to the slip angle within 250 Hz, but has obvious effect on the other position sensors deviating from the tire center plane. Especially the radial acceleration waveform of the side position of the tire, the two peaks of the waveform is significantly related to the slip angle. The grounding length at the center plane of the tire is related to the vertical load and tire pressure, but not to the slip angle. However, the grounding length deviating from other positions of the tire center plane is sensitive to the slip angle, and when the vertical load is larger or the tire pressure is lower, the slip angle affects the grounding length more obviously. The intelligent tire development platform developed provides an effective means for the study of tire grounding mechanism and tire slip angle estimation.
