<p>Vehicle and vehicle tire monitoring system, apparatus and method determine the load-induced deflection or deformation of a vehicle tire and based thereon, deflection-related information, such as tire load, molar air content, total vehicle mass and distribution of vehicle mass, may be provided. The fire deflection region or contact region (40) of the loaded tire is detected by sensing the acceleration of the rotating tire by means od an accelerometer (50) mounted on the tire, preferably on an inner surface such as the tread lining (15) thereof. As the tire rotates and the accelerometer is off of the contact region, a high centrifugal acceleration is sensed. Conversely, when the accelerometer is on the contact region and not rotating, a low acceleration is sensed. The deflection points delimiting the contact region are determined at the points where the sensed acceleration transitions between the high and low values.</p> |
