SYSTEM FOR CONTROLLING VEHICLE STABILITY USING PREDICTABLE ALGORITHM AND SELECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a system for controlling vehicle stability using some predictable algorithms and a selection method. SOLUTION: The system for controlling the vehicle stability comprises a means for imparting a longitudinal force to a tire, and a means for calculating a slip GOptby determining a value of a coefficient of frictionμifor each slip Gicorresponding to successive levels "i". As many target values GCnas the algorithms used can be obtained by using in parallel "n" pieces of calculation algorithms each determining the target value of the slip. The best of the target values GCnis selected as the optimum slip value GOptby comparing the "n" pieces of target values GCnwith the elimination of the minimum likely target values as a purpose. The comparison is made on the basis of a function f(λ) of a descriptor of a physical function of the rotation of the tire on a road surface, thus enabling a characteristic value to be calculated.
