Abstract
Active control engine mount system has been developed as a noise and vibration countermeasure technology in a completed vehicle powered by a 3-liter V6 cylinder-on-demand engine. In general, engine vibration is generated by torque fluctuation from its combustion under three-cylinder operation with low rpm. The research described in this paper focuses on the fact that engine vibration is estimated from a fluctuation in crank rotation, and feedforward control algorithm without an exclusive sensor for load or acceleration is established. Then a linear solenoid actuator with high response and low heat generation is specially developed and shows high reliability due to its unique coupling structure between an excitation plate within the hydraulic engine mount and a linear solenoid. Test results from the mount installed on a vehicle show that noise and vibration performance during three-cylinder drive is similar to those at full-cylinder drive.
