The increase of active safety will demand more and more electronic intelligence, if a drastic optimization of conventional systems is not possible any more. Starting from today's mechatronic systems, the trend leads via tomorrow's smart electronic systems to the future electronic networking of all intelligent vehicle systems. ...The paper describes the present status of these systems in Europe and the possibilities of increasing the active safety by using electronic intelligence.

The development of electronic intelligence and the continually increasing intensive knowledge of driving dynamics make it possible nowadays to conceive intelligent vehicle systems and to make such systems available for series production, which are capable of substantially enhancing the active safety of commercial vehicles.

Also it is possible to study the interior noise under an artificial force excitation applied to the trimmed body. The method is based on the theoretical background of TPA (= Transfer Path Analysis /1/ ) via matrix inversion. ...It was tested on a simple cuboid structure with an artificial force excitation. The comparison of the measured and recalculated SPL of the interior shows a good correlation.
