摘要： A load estimation system and method for estimating vehicle load includes a tire rotation counter for generating a rotation count from rotation of a tire; apparatus for measuring distance travelled by the vehicle; an effective radius calculator for calculating effective radius of the tire from the distance travelled and the rotation count; and a load estimation calculator for calculating the load carried by the vehicle tire from the effective radius of the tire. A center of gravity height estimation may be made from an estimated total load carried by the tires supporting the vehicle pursuant to an estimation of effective radius for each tire and a calculated load carried by each tire from respective effective radii.

摘要： A method of providing safety and maintenance vehicular service includes the steps: capturing information indicative of a vehicle status parameter electronically by means of a vehicle monitoring system; transmitting captured information through at least one vehicle connectivity system; transmitting captured information from the vehicle connectivity system to at least one portable device such as a cell phone and/or GPS unit; activating the portable device; activating analytical software utilized by the portable device; analyzing the captured information by the analytical software of the portable device; and conveying by sensory means useful processed information based upon captured information analysis to a user located within the vehicle. Advance communication of the processed information (e.g. identifying the service required) to at least one vehicle service provider externally located to the vehicle can be initiated and advance preparation of a job order and payment may be concluded online to expedite the repair procedure.

摘要： A system and method of estimating a load bearing on a vehicle tire includes an inflation pressure measuring sensor attached to the tire for measuring a tire cavity inflation pressure level; and one or more piezofilm deformation measuring sensors mounted to one or both of the tire sidewalls. The deformation measuring sensor generates within the tire footprint a deformation signal having signal power level indicative of a level of sidewall deformation within the footprint contact patch. Power-to-load maps adjusted for tire inflation pressure are generated and stored for the tire, the maps correlating a range of load levels to a range of signal power levels whereby operatively enabling a load level to be identified for each signal power level on an inflation pressure adjusted basis.

摘要： Estimating a load bearing on a vehicle tire includes an inflation pressure measuring sensor for measuring tire inflation pressure and generating a measured tire inflation pressure signal; a deformation measuring sensor mounted in a tire region of the vehicle tire, the deformation measuring sensor in the form of a piezoelectric bending sensor generating a deformation signal estimating a length of a tire contact patch length as the senor rolls through a tire footprint. Tire rolling speed is estimated from the deformation signal and a peak to peak amplitude variation within the deformation signal is detected and measured. An artificial neural network receives the tire rolling speed estimation, the contact patch length estimation, the amplitude variation within the deformation signal, and the measured inflation pressure of the tire. The artificial neural network adaptively interprets the input data and generates an output load estimation based thereon.
