A noise control device includes an engine to be mounted in a vehicle and a controller. The controller is configured to detect a state of the engine. The controller is configured to decrease a noise reduction performance due to a vibration input from a road surface in accordance with the state of the engine.

Noise control method and noise control device

An hybrid electric vehicle (HEV) drives front wheels by a motor-generator via drive shafts by use of electricity generated by an internal combustion engine (ICE). A lower portion of the internal combustion engine is locate on a front side of a lower portion of the motor-generator in the vehicle body with being distanced therefrom. A steering gearbox is placed between the internal combustion engine and the motor-generator and located on a front side of the drive shafts. According to this configuration, driving stability, steering feeling, and noise and vibration can be balanced at a high level.

Hybrid electric vehicle

A link mechanism, such as a panhard rod or the like, has a rod section and a collar section at each of its two ends. One collar section is supported on the case side bracket through a bushing. The other collar section is supported on the body side bracket through a bushing. A mass is provided at each collar section for limiting vibrations. Each mass is configured so that its principal inertia axis coincides with the principal elastic axis of its bushing in at least one direction of the bending vibration mode of the rod section so that the nodes of the bending vibration mode of the panhard rod also coincide with the principal inertia axis of the mass and thus the principal elastic axis of the bushing. This significantly dampens the vibrations imparted to the link mechanism.
