INVESTIGATIONS ON COMPLETE VEHICLE

A holistic view is necessary for the evaluation and optimization of the vehicle. Dynamic effects, acoustic behavior, influences on driving behavior and interactions in the system context should be taken into account. For example, a multi-channel speed and angle of rotation measurement on the cardan shaft, drive shafts, clutches and transmissions in combination with analog measured variables, such as accelerations and sound pressure, provides a comprehensive overall view of the vibration behavior of the powertrain.
