This chapter outlines some of the fundamental concepts when dealing with roll dynamics. In addition, it proposes an original algorithm to estimate lateral transfer load and tire/road vertical forces, regardless of the tire model. Three observers are developed for this purpose based on the Kalman filter approach. Observer OdFz L is linear and is based on a roll dynamics model and provides lateral load transfer estimation. Observers OFz L and OFz E are derived from linear and nonlinear models. The lateral transfer ratio (LTR) rollover index parameter is also calculated and discussed within the context of estimating wheel vertical forces. The potential of the estimation process demonstrates that it may be possible to replace expensive dynamometric hub sensors by software observers. Although the identified mass tends toward the real mass value, a weak point of this approach is the determination of the vehicle’s mass.
