Abstract EN
Establishing a prediction model, with linearity and few dof (degree of freedom), is a key step for the design of a control algorithm based on the modern control theory.
In this paper, such a model is needed for active suppression of vehicle longitudinal low-frequency vibration.
However, many dynamic processes in the vehicle have different effects on the vibration.
Therefore, a detailed coupling model is firstly established, considering the dynamics of the torsional vibrations of the driveline and the tire, the tire force nonlinearity, and the vehicle vertical and pitch vibrations.
Based on this model, sensitivity analysis is conducted and the results show that the tire slip, the torsional stiffness of the half-shaft, and the tire have great influences on the longitudinal vibration.
Then a three-dof model is obtained by linearizing the tire slip into damping.
A parameter estimation method is designed to obtain the model parameters.
Finally, the model is validated.
The time domain response, error analysis, and frequency response results demonstrate that the 3-dof model has a good consistency with the detailed coupling model.
It is suitable as a control-oriented model.
