Method and system for optimizing operation of vehicle control systems based on the dynamics of the vehicle

A system for optimizing performance of any one of a plurality of vehicle control systems based on the dynamics of the specific vehicle, the system comprising:

• a sensor for sensing a predetermined parameter associated with one of the vehicle control systems during a predetermined trigger event;
• and
• control logic for determining a critical vibration mode characteristic for the one control system based on the sensed parameter and operating the one vehicle control system based on the determined critical vibration mode characteristic, wherein the control logic, in determining the critical vibration mode characteristic, is further operative to determine if the vehicle control system requires optimization at a low frequency powertrain vibrations in a powertrain system and the sensor further operative to sense the rotational motion at a first predetermined location in the powertrain system upon sensing a predetermined event causing excitation at low frequency powertrain vibration if the vehicle control system requires optimization at the low frequency powertrain vibrations.
