Tire self-positioning system and positioning method therefor

A tire self-positioning method, comprising steps:

• S1:
• data acquisition:
• acquiring a wireless signal and a wired signal of a tire, wherein the wireless signal can index a corresponding time when a first signal reaches a reference point, the first signal comprises at least acceleration information of the tire, the wired signal comprises a second signal and corresponding position information of the tire, and the second signal comprises at least rotation angle information of the tire;
• S2:
• data conversion:
• calculating corresponding reference rotation angle information of the tire when the first signal reaches the reference point according to the wireless signal and the wired signal that are currently received;
• S3:
• data compensation:
• compensating for the reference rotation angle information acquired after reverse rotation of the tire if the reverse rotation of the tire exists;
• S4:
• data statistics:
• repeating steps S1 to S3, and performing deviation degree statistics on acquired queue of the reference rotation angle information;
• S5:
• determining a specific position of the tire corresponding to the first signal according to statistical result.
