🛞 Quarter-Car ABS Braking: Pacejka Tyre Curve, Slip Control and Stopping Distance (2D)

Side view of one braking wheel on dry, wet, snow or ice. Choose the road, the speed and the brake controller, then watch wheel speed, slip and speed fall. The Pacejka friction-slip curve, locked-wheel and ideal-slip stopping distances, and the closed-loop ABS result are computed from the quarter-car equations, with four in-page numerical checks. A braking-physics companion to the 3D ABS and tyre friction laboratory.
