摘要： PROBLEM TO BE SOLVED: To provide a vibration damper of a steering wheel capable of restraining vibration of the steering wheel on idling and traveling of a vehicle. SOLUTION: In a dynamic damper 22 installed in the steering wheel 14, a state for selecting a first resonant frequency for restraining the vibration of the steering wheel 14 in a direction perpendicular to an axis on traveling of the vehicle and the state for selecting a second resonant frequency for restraining the vibration of the steering wheel 14 in the direction perpendicular to the axis on idling of the vehicle can be switched by switching holding and non-holding states of a switching plate 28 provided with respectively interposing a first elastomer 26 and a second elastomer 30 between a mass body 24 and the steering wheel 14 in relation to the steering wheel 14. In a control unit, the resonant frequency of the dynamic damper 22 on traveling of the vehicle is regarded as the first resonant frequency, and the resonant frequency of the dynamic damper 22 in idling of the vehicle is regarded as the second resonant frequency.

摘要： PROBLEM TO BE SOLVED: To effectively reduce vibration generated at a specific portion of a vehicle body by vibration of an engine including "an explosion primary component and a component other than the explosion primary component" generated by explosion of mixed air.
SOLUTION: An engine torque presumption part 40A presumes torque Tq generated by the engine based on in-cylinder pressures Pc1-Pc4 of respective cylinders detected by in-cylinder pressure sensors 41a-41d provided on the respective cylinders. A specific portion vibration presumption part 40B determines magnitude and phase of force input to each of an active mount device and a passive mount device using the torque Tq, and presumes the vibration a (ω) of the specific portion based on the determined magnitude and phase of respective forces and transfer function of the vibration from the respective mount devices to the specific portion. A target determination part 40C determines target force to be generated by the active mount device from target vibration having the same magnitude as the vibration a (ω) and being the vibration of reverse phase and inverse function of transfer function of the vibration from the active mount device to the specific portion.

摘要： PROBLEM TO BE SOLVED: To provide a steering vibration reduction device capable of appropriately reducing steering vibration while an engine is idling in accordance with a tilt-telescope position of the steering.
SOLUTION: In the steering vibration reduction device, when the tilt-telescope position of the steering is changed to a position B, while the engine is idling during free running of a vehicle, a target vibration number ftg/B corresponding to a target vibration level Ltg of the steering at the position B is calculated and a vibration level of the steering is significantly reduced to the target vibration level Ltg as an idling speed of the engine is changed to a target idling speed Nitg/B corresponding to the target vibration number ftg/B. When the vehicle stops, the tilt-telescopic position of the steering is changed to a position A where a vibration level corresponding to a basic setting value Nis of the idle speed becomes lower than that at the position B and the vibration level of the steering is significantly reduced to a level lower than the target vibration level Ltg.
