Tire pressure detection method

Abstract

The invention discloses a tire pressure detection method. According to the detection method, a tire pressure display device detects and returns messages, and detection results are notified to users in forms of image frames and voice broadcast, and to warning persons who can directly correct errors and detect faults of tire pressure monitoring modules. The tire pressure display device comprises a host module, a plurality of tire pressure monitoring modules and a vehicle audio module, wherein the host module comprises a central processor and a receiver. Through the combination of the above elements, tire positions and tire pressure can be actively returned when the tire is pumped, the image frames and the voice broadcast are synchronously carried out, errors can be directly corrected, and the faults of the tire pressure monitoring modules can be detected and alarmed.

Description

technical field [0001] The present invention relates to a tire pressure detection method, especially a tire pressure display device and its detection method that can report tire information and correct errors through a car audio module, so as to actively report the tire position and tire pressure when the tire is inflated. Tire pressure, and synchronously broadcast with video and voice, and can directly correct the error and detect the warning of the fault of the tire pressure detection module. Background technique [0002] Whether the tire pressure of a car is normal is related to the safety of driving. Therefore, all car manufacturers list tire pressure monitors (or devices) as important options for driving equipment. However, the matching methods of each car are different, some are very complicated, and some It is relatively simple. It is very difficult for the technicians who change tires to understand the matching method, and they may not be able to do the matching oper...

Problems solved by technology

[0003] In view of the lack of the above-mentioned prior patents, the inventor of this case finally completed the tire pressure display device and its detection method of this case after numerous studies and improvements. That is, the purpose of the present invention is to provide a tire pressure display device and its detection method. The detection method can actively report the tire position and tire pressure when the tire is inflated, and simultaneously execute the video and voice broadcast, and can directly correct the error and detect the warning of the failure of the tire pressure detection module; the characteristics of the present invention are, That is, the car audio module will actively display when the tires are inflated, and the tire position and tire pressure will be played by voice through at least one speaker. First, it can be used as a reference for the pressure of the tires, and second, it can let the user know whether they have been paired correctly. effect, and as long as the user finds that the tire position is broadcast incorrectly, or broadcast as an unknown tire, he can directly correct the correction button on the screen of the car audio module; using the present invention can effectively solve the problem that the existing previous cases cannot be broadcast at the same time The tire position, and the disadvantage that it cannot be corrected on the display screen immediately when the message is wrong
