Abstract - Evolutional analysis for automotive systems of active safety (SAS) in respect to their control functions brings out that these vehicle components are worth consideration as an integral part of intelligent transportation system (ITS). In this case the two-level model for relations in "SAS Environment"-interplay can be devised. Micro-level refers to the interaction between a wheel and road surface, a macro-level is due to the spatial behavior of an automobile.
From this standpoint the classification and analysis for the present and long-term systems of active safety are examined in the present work:
- Adaptive systems
- Integrated systems
- Parallel systems
- Multilevel systems
- ITS-integrated systems.
For creating each of classes the certain analytical, informational and intelligent prerequisites must be performed.
The control philosophy with regard to the comparison of actual and potential (on the road conditions) movement parameters in chain "Driver Vehicle Tire Road - Environment" has been advanced to increase efficiency of SAS.
In conclusion the problems of full integration of intelligent SAS into ITS-structure are dis-cussed.
The final objective consists in the creation of intelligent system of active safety, which allows to forecast eventual development of road situation at all times in order to initiate the preventive control. For such system the following aspects are considered:
- Concept of "Road Analyzer"
- Necessary and sufficient dataware
- Main stages of intelligent control.
