| Summary: | Engine vibration and noise are one of the important factors that affect the comfort of drivers and passengers during driving, and active control technology of engine mounts can effectively realize dynamic adjustment of stiffness during low-frequency vibration and high-frequency vibration, reduce the vibration and noise generated by the engine under different working conditions and significantly enhance driving comfort. This paper uses control theories such as feedforward control and feedback control to design a fusion control strategy, and combines the suspension control model to form a suspension active control scheme. The control scheme is verified and optimized in laboratory and in actual vehicle. Test results show that the active control technology of engine mount has a significant control effect on engine vibration in various frequency bands, and the vibration amplitude of engine in a specific frequency band is reduced by more than 80%, which verifies the effectiveness of the method. |
