Motor vehicle's tire pressure monitoring method, involves measuring magnitude value of effort of wheel by sensor, and delivering informational message, when magnitude value of effort is different from registered value of another wheel

摘要

The method involves measuring periodically magnitude value of force, by a force sensor, applied at the level of a wheel by a sensor, in which thickness of the tire is variable. A informational message is delivered by a delivering unit (2) when the magnitude value relative to the wheel is different from a value recorded for other wheels and for the previously recorded value of the same wheel. A frequency analysis over the applied force is carried out for determining beat frequency of the wheel and for determining pumping frequency of a case of the vehicle over a suspension system. An independent claim is also included for an installation device for monitoring pressure of tire of a motor vehicle.
