Patent ID: 11351820

Abstract:
Embodiments of the present invention relate to the technical field of automobiles and disclose a tire positioning method and apparatus, an electronic control unit (ECU) and a tire pressure sensor. The method includes: successively controlling, within a transmission cycle, one of L exciter sets to send a low-frequency signal, L being an integer greater than 1; receiving high-frequency signals fed back by N tire pressure sensors according to the low-frequency signals, N being an integer greater than 1; determining a correspondence between one of the L exciter sets and M tire pressure sensors according to the high-frequency signals, M being an integer greater than 1; and after a quantity of transmission cycles reaches a preset threshold, determining a tire corresponding to each of the N tire pressure sensors according to the correspondence between the exciter set and the M tire pressure sensors determined in each transmission cycle. The tire positioning method is accurate and reliable.
