    摘要： A dynamic load estimation system and method for estimating a vehicle load is disclosed. The system comprises at least one tire (12) supporting a vehicle (10); tire sensor means (14) mounted to the one tire (12), the sensor means (14) being operable to measure a tire deformation of the one tire (12) and generate a load-indicative raw signal conveying measured deformation data; load estimation means for determining an unfiltered load estimation on the tire from the load-indicative raw signal; road roughness estimation means for determining a road roughness estimation; filtering means for filtering the unfiltered load estimation by the road roughness estimation; and load estimation means for determining a filtered load estimation on the one tire from the filtering means.

    摘要： At the inner liner portion (22) of a tire (20) with a sensor, a pair of sensors consisting of first and second strain gauges (11A, 11B) are arranged at line-symmetric equidistant positions in the axial direction with respect to the axial center of the tire, and the distortion of a tire tread is measured. From a strain rate waveform obtained by time-differentiating a distortion waveform measured by the pair of sensors (11), stepping time strain rates, i.e. the peak values of strain rate occurring when the tire tread enters the contact part with the road surface, are detected as the indexes of deformation rate. Using the ratio of deformation rate indexes detected by the pair of sensors, and a map (15M) stored in a storage means (15) and indicating the relation between predetermined ratio of deformation rate indexes and the tire slip angle, slip angle of a vehicle under traveling conditions is estimated thus estimating the tire slip angle of the vehicle under traveling conditions precisely.
