Problems solved by technology

However, the direct type has the following disadvantages: product cost and installation and maintenance cost are relatively high, at least 4 sensors, 4-5 batteries, four radio transmission devices, a central radio receiving processor, display and sound and light alarm devices, etc. are required. Requires removal of all tires to complete installation
However, the indirect method has the following disadvantages: the tire pressure value of each tire cannot be displayed
However, the composite type has the following disadvantages: the cost is still relatively high compared with the simple indirect type
It is impossible to make judgments on other important parameters of the tire such as aging, wear, load, etc., and remind the user in time

Embodiment 1

[0047] Such as figure 1 As shown, the embodiment of the present invention proposes a tire pressure monitoring method, including:

[0048] S11. Download the actual tire pressure values, tire usage time, tire mileage, tire speed limit, tire load limit, and tire wear parameter data of the four tires A, B, C, and D from the human-computer interaction interface terminal.

[0049] At any time through the external human-computer interaction interface associated with this device, if there is a "confirmation" operation, it will automatically download A, B, and C from the human-computer interaction interface terminal through the vehicle bus communication interface, serial communication or other wireless communication methods. , D The actual tire pressure value of the four tires, tire usage time, tire mileage, tire speed limit, tire load limit, tire wear and other parameter data, which also includes date and time information, alarm automatic shutdown time, etc.

[0050] If the setting o...

Embodiment 2

[0101] Such as figure 2 As shown, the embodiment of the present invention provides a tire condition monitoring device based on learning multi-sensing, including: microprocessor, storage unit, data communication unit, sound alarm unit, light alarm unit, power management unit, radio frequency unit and A temperature sensor; the storage unit stores the computer program used by the method in Example 1. Use the bus communication interface to read the vehicle ABS wheel speed sensor (pulse generator), vehicle mileage, driving speed, vehicle identification code, brake opening and closing degree, accelerator opening and closing degree, steering wheel angle and other metadata, to achieve multiple perception, deep learning, parameters Calibration, error and interference processing, intelligent analysis, calculation of vehicle tire pressure and quantitative evaluation of tire status.

Abstract

The invention provides a tire condition monitoring method based on learning type multiple perception. In this method, the minimum mileage of one or more vehicles is used as the analysis unit, and the data collected from the vehicle bus are corrected and accumulated separately for the ABS pulse data of the coaxial tires according to the errata values ​​obtained in the learning mode; if this process If there is an abnormality in the sum of the ABS pulse data of the diagonal tires, use replacement or filling to ensure the integrity of the monitoring cycle; the individual accumulated data of the ABS pulse data of the 4 tires obtained in the learning mode after correcting the errata value is used as the comparison object. The real-time tire pressure values ​​of 4 tires are the reference, and the precise tire pressure value of the next cycle is calculated by looking up the table; the early warning and alarm quantification processing of tire health status; data output, status display and sound and light alarm processing. The invention also provides a tire monitoring device. The method can monitor various tire information, and the user can obtain comprehensive tire status information.

Description

technical field [0001] The invention relates to the technical field of vehicle monitoring, in particular to a tire condition monitoring method and device based on learning-type multi-sensing. Background technique [0002] According to relevant experiments and verifications, if the car is driven for a long time without the tire pressure meeting the standard, the wear and damage speed of the tire is 2 to 3 times that of when the air pressure meets the standard. An important factor in comfort and safety. Therefore, tire pressure monitoring is of great significance to improve driving safety, reduce fuel consumption and reduce tire wear and puncture. [0003] At present, the tire pressure monitoring technology adopted in the world is mainly divided into three types: direct type, indirect type and composite type. [0004] The working principle of the direct type is to install a pressure sensor inside the tire or on the air nozzle to directly measure the tire pressure, use a wire...
