摘要: The natural vibration frequency of a roll resonance which does not occur since the engine rotation number is high in normal operation range an detected at time start or stop when lower than range, and thus roil can be with good accuracy. A current generated by electromotive force actuator active isolation support device excited immediately before stopping its rotation, used to detect engine, suppressed controlling based on frequency, thereby only eliminating need specific detection sensor, but also effectively reducing becomes strong.
