Recently, customers have been demanding increased safety features in cars. Meanwhile, auto magazines now seek to publish the stopping distance. Further, the car development period has become shorter. For all these reasons, a precise estimation of the ABS stopping distance has grown important.

A few steps that can be taken to improve accurate simulations of the ABS stopping distance are as follows:

1
Development of the tire hysteresis concept, its confirmation by test results, and then its application.
2
Free diagram development of the wheel combining ideal braking force, real braking force, and specific tire quality.
3
Modeling of HCU.
4
Application of ABS and EBD logic.
5
Application of booster characteristic to the section of early braking.
