Abstract
System, methods, and other embodiments described herein relate to tire models based on neural-ExpTanh parameterization. In one embodiment, a method includes operating a vehicle with a control framework incorporating an ExpTanh function; calculating prior slip data based on measurements obtained by the control framework; selecting a confidence parameter; using a first predictive model to determine ExpTanh parameters based upon the prior slip data, the measurements, and the confidence parameter; and inputting a slip parameter and the ExpTanh parameters into the ExpTanh function to estimate a tire force.
