Abstract: Embodiments of the present invention relate to the technical field of vehicle electronics and disclose an upgrading method and apparatus for a tire pressure monitoring module and a tire pressure sensor. The method is applicable to a tire pressure sensor including a signal receiving module. The method specifically includes: controlling the signal receiving module to receive an upgrade file and save the upgrade file; and waking up a tire pressure monitoring module, and controlling the tire pressure monitoring module to read the saved upgrade file and upgrade the tire pressure monitoring module based on the upgrade file. The embodiments of the present invention can realize wireless upgrading of the tire pressure sensor, thereby improving the upgrading efficiency, reducing the upgrading costs, and improving the safety in upgrading of the tire pressure sensor.

Abstract: The present invention relates to the field of tire pressure detection technologies, and discloses a tire pressure sensor, including: a sensor assembly provided with a through hole; a valve assembly including a valve rod, a valve cover mounted to one end of the valve rod, a rod sleeve sleeved between two ends of the valve rod and a fastener connected to the other end of the valve rod through threads, one of the fastener and the valve rod passing through the through hole, and the fastener and the valve rod clamping the sensor assembly, where there are at least two sets of valve assemblies, the at least two sets of the valve assemblies being alternatively connected to the sensor assembly, a rod sleeve of one of the at least two sets of the valve assemblies being made of a metal material, and a rod sleeve of the other of the at least two sets of the valve assemblies being made of a rubber material.

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.
