  • Adaptive Rolling Radius Estimation - DiVA portal
    a tire The effective rolling radius of a tire is affected by several different factors As to not confuse change in external factors with actual tire tread wear, there is therefore a need to compensate the effective rolling radius to nominal conditions, to make sure that the change in compensated rolling radius is only due to the tire tread
  • Effective radius of a tire and rolling resistance based on . . .
    Measure the effective circumference to calculate the diameter To do this mark the tire, and the ground with paint or a soapstone Move the vehicle until the mark on the tire contacts the ground again, and mark the ground Then measure the distance between the marks on the ground This distance is the effective circumference C = 2 * pi * r
  • Calculating Rolling Resistance with a Parametrical Equation
    To calculate the effective rolling radius is needed the tire static stiffness There are some variants of equations for this Here is adopted this version: There is a problem with this method; there will be a deceleration for a car about 0- to 0 4 m s^2, average 0 2 m s^2 for coast from 100 km h
  • Estimation of vehicle tire effective rolling radius and . . .
    In this paper, a new method is designed to estimate the effective rolling radius and the vertical wheel road contact force using an extended Kalman filter and the Pacejka magic formula Moreover, it allows the estimation of the longitudinal force, the rolling resistance force, and the longitudinal slip The method is designed in four blocks
  • Rolling Resistance Measurement and Model Development
    The results are summarized in a table showing that the effective rolling radius is insensitive to parameter variations, whereas the rolling resistance (and hence the total energy loss per revolution) is insensitive to rolling speed, convection loss, and friction, but increases significantly with increasing normal load, tread profile, and tread
