Electronic Stability Program with Vehicle Sideslip Estimation

The recently used vehicle stability algorithms primary use yaw rate and lateral acceleration as reference signals while vehicle state could be defined by yaw rate and vehicle sideslip angle. Furthermore onboard later acceleration measurement is overlayed with significant disturbances. Approximate enough vehicle sideslip estimation ensures the opportunity of correct vehicle state observation and deducing other important vehicle parameters as corrected lateral acceleration for instance. By using this additional information new vehicle state definitions and interventions are realizable. The front and rear axles' cornering stiffness coefficients could be estimated from the vehicle sideslip angle - after some filtering these signals can show which wheels could be braked. Or new reference models could be set up - these models will be adaptive, not like the currently used empirically defined models. Adaptive means that it considers adhesion coefficients, tyre characteristics and vehicle load at the same time - not as the recently used systems. Predicted vehicle state definition could also be done, which is able to show dangers before they start to develop.
