Model based calculation of friction curves between tyre and road surface

The estimation of adhesion characteristics during transients of high acceleration phases is very necessary for several systems, for example ABS or vehicle stability control. For the estimation of these friction curves one needs to know the braking force distribution. In this paper a model is presented, which allows the calculation of the braking force distribution of the car's braking system using only one pressure sensor. With the model based calculation of the braking force distribution the friction curves between the tyre and road are estimated.
