The heights of vehicles can be inexpensively estimated by: detecting wheel speeds representing the speed of each wheel (step ST11); performing a frequency analysis of the detected wheel speeds of pairs of left and right wheels, and calculating the respective wheel speed characteristics of the left and right wheels at a gain-specific frequency (step ST12); calculating the difference in gain between the left and right wheel speeds on the basis of the calculated wheel speed characteristics of the left and right wheels (step ST13); and estimating the height of a vehicle on the basis of the correlation between the wheel heights with respect to the bodies of the wheels and values based the wheel speeds and a road surface inputs inputted from a road surface to the vehicle wheels (i.e., wheel speed/road surface input gain), and the difference in gain between the left and right wheel speeds (step ST14).
