Abstract

The invention discloses a TPMS leaving-assembly calibration method andn TPMS leaving-assembly calibration equipment based on a bidirectional tire pressure. The TPMS leaving-assembly calibration method comprises the following steps of S1, connecting a WiFi connector with an automotive OBD interface, connecting handheld calibration equipment with the WiFi connector through WiFi communication, accessing into an automotive CAN network by the handheld calibration equipment after communication connection through the automotive OBD interface, and finally forming communication connection with a tire pressure monitoring controller; S2, transmitting a calibration instruction by the handheld calibration equipment to the tire pressure monitoring controller, and after the tire pressure monitoring controller receives the calibration instruction, performing sensor matching; and S3, successively performing calibration according to a sequence of left front, right front, left back and right back, and successively performing calibration according to the step S2, thereby finally finishing TPMS system calibration. The TPMS leaving-assembly calibration method and the TPMS leaving-assembly calibration equipment can realize online tire pressure calibration and furthermore have advantages of simple operation and effective production efficiency improvement.

Description

technical field [0001] The invention belongs to the technical field of automobile tire pressure monitoring, and in particular relates to a bidirectional tire pressure-based TPMS off-line calibration method and TPMS off-line calibration equipment. Background technique [0002] The tire pressure monitoring system is referred to as "TPMS", which is the abbreviation of "tire pressure monitoring system". The principle of tire pressure monitoring technology: By recording the tire speed or electronic sensors installed in the tires, various conditions of the tires are automatically monitored in real time, effectively avoiding traffic accidents caused by tire pressure problems when the car is driving at high speed. [0003] The existing tire pressure monitoring system calibration method mainly requires a separate calibration device through the tire pressure monitoring controller to drive devices similar to low-frequency trigger units to trigger the tire pressure monitoring sensors on...
