摘要： A method for controlling a semi-active engine mount is provided to increase both NVH performance and driving performance of a vehicle and reduce noise and vibration generated under specific driving conditions. The method includes storing real-time vehicle speed data at intervals of a predetermined time and determining whether an engine is in an idling state. In response to determining that the engine is in the idling state, determining whether a current driving state of the vehicle corresponds to predetermined conditions in which noise and vibration performance is prioritized based on vehicle speed change information. The semi-active engine mount is adjusted to be in an on state, upon determining that the current driving state of the vehicle in the idling state of the engine corresponds to the predetermined conditions.

摘要： An active engine mounting device is provided. The active engine mounting device includes upper and lower liquid chambers partitioned by a valve unit and adjusts a vibration and a load input from an engine in response to a driving condition while a fluid passes through the valve unit and attenuates the vibration and the load. The active engine mounting device includes an insulator that encloses a core integrally formed with a mounting bolt and elastically deformed based on the load applied to the core. A main case is disposed at a circumference of a lower end portion of the insulator. A diaphragm is disposed under the main case. The valve unit is configured to selectively pass the fluid through three channels based on operation of the valve. An actuator is disposed through an auxiliary case to drive the valve in an axial direction.

摘要： Proposed is a transmission mount for a vehicle in which the structure of an upper insert and a lower insert integrated with a single bridge among components of the transmission mount is improved to reduce the static stiffness in the right-left direction (i.e., the Y direction) of the transmission mount. The strength of the transmission mount in the front-rear direction (i.e., the X direction) and the static stiffness in the top-bottom direction (i.e., the Z direction) is reinforced so that the pitching motion and the vertical bounce behavior of the transmission may be efficiently controlled. Accordingly, booming noise caused by the rolling motion of the transmission is minimized, thereby improving NVH performance and meeting driving performance.
