Abstract EN
Accurate estimation of longitudinal force and sideslip angle is significant to stability control of four-wheel independent driven electric vehicle.
The observer design problem for the longitudinal force and sideslip angle estimation is investigated in this work.
The electric driving wheel model is introduced into the longitudinal force estimation, considering the longitudinal force is the unknown input of the system, the proportional integral observer is applied to restructure the differential equation of longitudinal force, and the extended Kalman filter is utilized to estimate the unbiased longitudinal force.
Using the estimated longitudinal force, considering the unknown disturbances and uncertainties of vehicle model, the robust sideslip angle estimator is proposed based on vehicle dynamics model.
Moreover, the recursive least squares algorithm with forgetting factor is applied to vehicle state estimation based on the vehicle kinematics model.
In order to integrate the advantages of the dynamics-model-based observer and kinematics-model-based observer and improve adaptability of observer system in complex working conditions, a vehicle sideslip angle fusion estimation strategy is proposed.
The simulations and experiments are implemented and the performance of proposed estimation method is validated.
