Abstract
This paper is a theoretical and experimental continued witch has make by authors starting with 1992.
The initial filling has been to be optimized the driver automotive comfort with optimization of damping coefficient of suspension having influences on active and semiactive suspension.
Next time, we assumed in our view and the influence of disturbing elements mislead by road over entire transmission-suspension car system.
In this paper we wish to investigate witch is disturbing elements influences mislead by driver car (naturally we cannot covered all types, but we can build a equivalent relation for this).
