Tire state estimation based on measured accelerations at the tire inner liner using an extended Kalman filter design
conference paper
In this work, a tire state estimator (TSE) was developed and validated using experimental data. A tire has been equipped with an accelerometer on the inner liner measuring radial acceleration. First, an empirical model was developed consisting of a basic shape function for the acceleration and relations that relate the parameters of this function to tyre states. Second, a model-based estimator for the vertical force was developed using this model. The estimator is composed of a peak synchronization algorithm and an Extended Kalman Filter. The TSE shows accurate vertical load estimation, fast convergence capabilities and noise filtering.
