The Theoretical Concepts for Pre-Extreme ABS 2002-01-2185
The analysis of existing systems of automotive active safety (SAS) shows that the antilock braking system (ABS) is a kernel for anyone of them. However circle of the tasks, which should be decided by SAS, is complicated, and the algorithms approaches are traditionally based on threshold control.
Basing on the researches of interactions within a chain ‘automobile - wheel – road’ a new so-called pre-extreme control philosophy for ABS may be offered. It is based on the discovered regularities between the tire grip and wheel slippage.
For the given philosophy the family of ABS algorithms is offered which allows realising both discrete and continuous control of wheel operation.
