Identification of the Dynamic Parameters of a Car

Abstract

<div class="htmlview paragraph">Accurate values of the dynamic parameters of a car (mass, center of mass, inertia) are needed in order to improve the dynamic control and simulation of the car. It is important to know the value of each of them in order to notify the fields of numerical tools. In this paper a robotics approach is developed. It is based on a multi-body description of the system that allows the automatic computation of the dynamic identification model, which is linear with respect to the parameters to identify. They are estimated using a weighted least squares method. Practical results are given for the parameters of a 406 Peugeot car.</div>
