发明名称 Vehicle stability control system using an invariant function characterising all type of tyres
摘要 The braking control system uses a regression technique, in order to determine the optimum conditions in order to achieve braking, whilst preventing skidding, for pneumatic tyres. The system provides control of the stability of a vehicle fitted with pneumatic tyres. A controller uses at least one sliding parameter (GOpt) for the tyre, corresponding to a predetermined adherence coefficient (mu), to seek to maintain the operation of the tyre at a predetermined target value of the pressure derivative (Fcible). The trajectory control uses an optimal value corresponding to the maximum value of the pressure derivative. Further calculation is carried out using X, representing the sliding (G) or the angle of the derivative (delta), and Y, representing the adherence coefficient (mu) or the pressure derivative (F). Using a regression process, coefficients are calculated in order to model a variation curve. With the aid of this, a target value is determined.
