PARAMETRIC IDENTIFICATION OF THE CAR DYNAMICS

摘要

The aim of this paper is to give a general and unifying presentation of the identification issues of a passenger car using the Denavit and Hartenberg robotic formalism for the modelling. The desired parameters are the dynamic parameters of the car and the parameters of the suspension and the tires. The kinematics and dynamic models are automatically calculated using the software package SYMORO+. The identification is based on the use of the inverse dynamic model. Parameters are estimated using a weighted least squares method. The weighting procedure is developed. Practical results are given for a 406 Peugeot car.
