Abstract: In the present work a 235/75R15 tyre 3D finite element (FE) model was developed using the commercial software package ABAQUS. The finite element model considers the severe nonlinearities due to a tyre's complicated geometry, hyperelastic properties of the rubber material, contact between the tyre and the road, and the reinforcing bars inside the tyre's structure. The FE model was utilised to implement a braking event of antilock braking system (ABS) controller logic. The ABS controller was developed based on a commercially available system and the logic was coded in Fortran 77 and implemented in a UVAMP ABAQUS subroutine. The detailed 3D tyre model and the FE ABS model are discussed in detail. The results show that the ABS logic is capable of maintaining the minimum slip ratio to avoid tyre sliding.
