Identification of tire force characteristics using a Hybrid method
A Hybrid method for identification of tire model unknown parameters in the so-called Magic Formula has been applied. Firstly, the Hybrid method uses Genetic Algorithm as a global search methodology with a high exploration power. Secondly, the best results of Genetic Algorithm is used as starting values for LevenbergMarquardt algorithm as a gradient-based method with high exploitation power. Results show the Hybrid method has outstanding benefits such as high convergence speed, high accuracy, and null-sensitivity to the starting values of unknown parameters.
