Method and system for controlling semi-active engine mount

A method for controlling a semi-active engine mount having a first flow path, a second flow path, and an actuator configured to open and close the second flow path, the method comprising:

• storing, by a mount controller, real-time vehicle speed data at intervals of a predetermined time;
• determining, by the mount controller, whether an engine is in an idling state;
• determining, by the mount controller, 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, in response to determining that the engine is in the idling state;
• and
• adjusting, by the mount controller, the semi-active engine mount to be in an on state to cause the actuator to open the second flow path, in response to determining that the current driving state of the vehicle in the idling state of the engine corresponds to the predetermined conditions in which noise and vibration performance is prioritized.
