The invention relates to the technical field of automobiles, and discloses a tire slip angle real-time identification system which comprises an intelligent tire sensor, an acceleration sensor, a processor and an operation module. The intelligent tire sensor is used for collecting elastic lateral deformation data caused by lateral deviation of a tire belted layer and lateral deformation data caused by lateral deviation of a tire tread, and the processor is used for processing the received elastic lateral deformation data caused by the lateral deviation of the tire belted layer and the received lateral deformation data caused by the lateral deviation of the tire tread. The operation module reads the cornering stiffness of the front and rear wheels of the automobile. According to the system for recognizing the tire slip angle in real time, the tire slip angle is calculated by reading a sensor, a vehicle TBOX and partial parameters in a database through two different means for measurement and calculation, fusion calculation is conducted on the tire slip angle and the tire slip angle through Kalman filtering, the driving condition of the vehicle is analyzed from multiple dimensions, and the real-time recognition of the tire slip angle is achieved. And real-time tire slip angle identification is realized. And the stability and the accuracy of data are improved.
