PROBLEM TO BE SOLVED: To accurately estimate the wheel load on a wheel, taking into consideration the factors affecting the frequency components of vibration, having a torsional resonance frequency included in wheel velocity data. SOLUTION: This wheel load estimating device 10 extracts vibration gain Gne of the torsional resonance frequency, from the wheel velocity data acquired based on the signal detected by a wheel velocity sensor, corrects the vibration gain Gne by various parameters (tyre internal pressure P, etc.), finds vibration gain Gneh, acquired when the various parameters are each in a definite referential state, and the wheel load on the wheel is estimated from the vibration gain Gneh. This allows the wheel load to be estimated accurately while taking into consideration the factors affecting the vibration gain Gneh. COPYRIGHT: (C)2006,JPO&NCIPI
