Model supported estimation of float angle - using vehicle speed from ABS system, steering angle sensor to derive transverse speed and hence float angle

摘要

The circuit is used to determine the transverse speed of a vehicle and/or its float angle. It estimates the transverse speed from the parameters, longitudinal speed, yaw angular rate and steering angle using a model supported estimation technique. The float angle is then derived by forming the ratio of the vehicle transverse speed to its longitudinal speed. USE/ADVANTAGE - For use in evaluating and controlling the stability of a vehicle. The method is implemented more economically then conventional ones. It requires only a pass-produced steering angle sensor and the vehicle speed is obtained from an ABS system.
