Modern anti-lock braking systems (ABS) are based on tyre slip observation. Tyre slide conditions are estimated considering, as a rule, a fully stiff carcass. During braking motions, tyre – road forces cause carcass strain and, consequently, slip variation respect to the values estimated with reference to no compliance systems. In this paper, the influence of the “effective slip”, estimated considering carcass compliance, on bus anti-lock braking systems is evaluated. To this aim, a simplified tyre carcass model has been realized. This one, combined with a tyreroad interaction model, allows defining the effective slip. Simulations have been carried out employing a quarter vehicle model and braking performances have been evaluated for an anti-lock system equipped with an algorithm able to estimate the effective slip.

Abstract
Modern anti-lock braking systems (ABS) are based on tyre slip observation. Tyre slide conditions are estimated considering, as a rule, a fully stiff carcass. During braking motions, tyre – road forces cause carcass strain and, consequently, slip variation respect to the values estimated with reference to no compliance systems. In this paper, the influence of the “effective slip”, estimated considering carcass compliance, on bus anti-lock braking systems is evaluated. To this aim, a simplified tyre carcass model has been realized. This one, combined with a tyreroad interaction model, allows defining the effective slip. Simulations have been carried out employing a quarter vehicle model and braking performances have been evaluated for an anti-lock system equipped with an algorithm able to estimate the effective slip.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
