Embodiment Construction

[0061] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0062] Such as figure 1 As shown, on the one hand, this embodiment provides a TPMS system automatic matching method for matching the transmitter and receiver of the TPMS system, including:

[0063] Vehicle speed detection step: detecting vehicle speed information;

[0064] Data processing step: process and load the detected vehicle speed information into the radio frequency message data conforming to the communication protocol;

[0065] RF radio frequency sending step: sending the radio frequency message data;

[0066]RF radio frequency receiving step: for receiving and parsing at least four radio frequency message data sent by an even number of transmitters, the radio frequency message data inc...

Abstract

The invention provides an automatic matching method and device of a TPMS (Tire Pressure Monitoring System). The method comprises a car speed detection step, a data processing step, an RF (radio frequency) transmitting step, an RF receiving step, a matching mode judging step, a transmitter locking step and an automatic matching step, wherein the automatic matching step comprises the following sub-steps: distinguishing transmitters which are arranged on a left wheel and a right wheel through transmitter ID (identification) or the value of a fixed byte in RF message data; collecting a power value or a frame loss rate value corresponding to the RF message data, and judging transmitters which are arranged on a front wheel and a rear wheel through the collected power value or the collected frame loss rate value; and automatically matching the transmitters with receivers on the corresponding wheel positions. According to the automatic matching method and device, no additional workstation is needed for an assembly line of a car factory, and the assembling step is not influenced; the transmitters and the receivers can be matched automatically without a special tool for the after sale; manual operation is not needed, the matching is completed in the traveling process, and the matching success rate of the TPMS is increased; the product cost and after-sale cost of the TPMS can be reduced.

Description

technical field [0001] The invention relates to the technical field of automatic matching of TPMS systems, in particular to a method and a device for automatically completing the matching of a front-mounted TPMS system of a passenger car during use by a user. Background technique [0002] Currently, the tire pressure monitoring system (Tyre Pressure Monitoring System, TPMS) pairing technology has the following types: [0003] 1) The TPMS receiver is in the pairing mode, inflate or deflate the tire or take other methods that can trigger the transmitter to send RF message data, the receiver receives and matches with the transmitter; [0004] 2) The TPMS receiver is in the pairing mode, and the low-frequency command is sent through the handheld instrument to trigger the transmitter to send RF message data, and the receiver receives and matches with the transmitter; [0005] 3) Two-way communication between the TPMS transmitter and the receiver, the receiver and the trigger are...
