PURPOSE: An engine mount device and a control method of a hybrid vehicle are provided to reduce vibration and noise of a restarting of an engine according to an idle stop and go function for low frequency and high displacement vibration by selectively generating the intensity of a magnetic field of a mount according to the state of the engine and changing the spring property of MR(Magneto-Rheological) fluid filled in the mount. CONSTITUTION: A control unit changes the spring property of MR fluid(7) filled in a mount(M) by a magnetic field changed by an electric current according to an operation of an accelerator pedal(P) and a working state of an engine at plural mounts for supporting the engine by a sub frame(F) combined at a lower part of a front vehicle body and insulating vibration. The control unit is composed of a controller(ECU,1) for receiving signals from an accelerator pedal sensor(3) for detecting an operation of the accelerator pedal and an engine sensor(3') for detecting the whole state of the engine; a switching member(2) for switching power of a battery according two control signals of the controller; and first and second signal lines(1a,1b) for connecting among the mount, the switching member, and the controller to control the activation rate of the MR fluid by supplying power to the mount by the switching member.
