Braking performance is one of the important performances of the vehicle tests because that is related to the driver and pedestrian security, ABS(Anti-lock Brake System) can improve vehicle braking/stability performance, So nowadays many of cars are equipped ABS basically, ABS braking performance is determined from optimum combination of ABS logic, tire traction and friction characteristics of brake pad. In this paper, we developed performance measurement index to predict ABS braking, To do this, we measured vehicle characteristics such as load transfer and ABS working slip ratio during braking with V-BOX and measured tire characteristics like longitudinal friction with Flat-trac Ⅲ test machine, And then, considering both vehicle and tire characteristics, finally we predicted ABS braking performance, This index has high correlation with ABS braking distance and can give us intuition to tune the tire design to improve the braking performance.
