Abstract: The present invention provides a vehicle bus-based communication method and apparatus, a computer device and a storage medium. The vehicle bus-based communication method includes: monitoring data flows transmitted through a vehicle bus by vehicle electronic control units; determining undetected data flows in to-be-obtained data flows when the monitoring reaches a first time length; broadcasting data flow obtaining requests through the vehicle bus, the data flow obtaining requests specifying queries for the undetected data flows; and obtaining data flows that are fed back through the vehicle bus in response to the data flow obtaining requests. When data flows of a vehicle are obtained through a vehicle bus, data flows on the vehicle bus are first obtained in a monitoring manner, thereby ensuring data flow obtaining efficiency.

Abstract: The present invention relates to the field of vehicle correction, and provides a calibration system and a calibration bracket thereof. The calibration bracket includes: a base, a stand assembly and a beam assembly. The stand assembly is fixedly connected to the base. The beam assembly is supported by the stand assembly, and includes a beam, the beam being configured to mount a calibration element and including a left beam portion, a right beam portion and a connecting portion, the connecting portion being supported by the stand assembly, one end of the connecting portion being pivotally connected to the left beam portion, and the other end of the connecting portion being pivotally connected to the right beam portion. In the foregoing structure, the left beam portion and the right beam portion can respectively rotate toward each other relative to the connecting portion, to fold the beam assembly, so that a volume of the calibration bracket can be reduced to facilitate shipment.

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.
