The active control engine mount system decreases engine vibration at a low engine speed using the vacuum switching valve (for active control engine mount). The vacuum switching valve (for active control engine mount) is controlled by a pulse signal transmitted to the vacuum switching valve (for active control engine mount) from the ECM. The frequency of this pulse signal is matched to the engine speed to decrease engine vibration.
