Design of Vehicle Critical State Parameter Observer
Transverse angular velocity and center-of-mass lateral deflection of a vehicle are vehicle state pa-rameters that are closely related to the stability of vehicle maneuvering.In view of the high cost of sensors and the difficulty of measuring key state parameters such as center of mass lateral deflection,this paper selects the two-degree-of-freedom model of the vehicle containing the parameters of traverse angular velocity and center of mass lateral deflection as the reference model,and builds a Kalman observer based on the platform of Matlab/Simulink,and verifies the accuracy of the observer prediction with the simulation of the Carsim software,and the actual output curve and the prediction curve are basically in good agreement.By comparing the actual output curve with the predicted curve,both of them are basically consistent and have high application value.
