Problems solved by technology

[0007] This method effectively made possible very early detection of a tire slowly leaking air, but proved ineffective when the air leak affected both tires being monitored in a similar manner

Embodiment Construction

[0047] Fig. 1 shows a simplified diagram of a system for monitoring vehicle tires with a device implementing the method of the present invention. The simplest form of the monitoring system includes an electronic module 10 and a device 20 for processing and presenting data. The electronic module is arranged in the internal cavity of each tire of the vehicle of interest. For example, in the case of a construction vehicle, the electronic module can be fixed to the inner surface of the tire with a rubber sheet. The device 20 may be arranged in the chassis of the vehicle. The device can also be on the outside of the vehicle.

[0048]Each electronic module 10 mainly includes: a sensor 11, which is used to measure at least the pressure and temperature of the internal fluid in the inner cavity of the tire; a microprocessor 12, which is used to manage the measured values ​​and preprocess them; and an antenna 13, which is used The measured data for the emission. The electronic module may al...

Abstract

Method of processing data in a vehicle tire monitoring system. For a first given period of time, referred to as the reference period, a device calculates, for each class of temperature supplied, the corresponding mean pressure in a given tire. Then, for at least a second given period of time, the device calculates, for each class of temperature supplied, the corresponding mean pressure and the difference between this mean pressure and the reference mean pressure, and the device calculates the mean value of these differences.

Description

Technical field [0001] The invention relates to a tire monitoring system. It focuses more specifically on the use of tire measurements for the purpose of giving one or more warnings. Background technique [0002] Many devices have been proposed, such as the device in patent US 4,703,650, for sending the inflation pressure measurement value of each tire to the central unit in a conventional manner, accompanied by a measurement value of the temperature of the internal air of the tire, if available. [0003] However, knowing the inflation pressure is not enough to give the driver reliable and useful information. I am afraid that compared with the actual use, continuous query of this information may be more boring. This is because tire pressure and / or temperature measurement values ​​will change dramatically during operation due to tire heating caused by its hysteresis loss, brake heat dissipation effects, and load transfer that cause a slight change in tire volume. [0004] This is ...
