A system and method of controlling engine vibration mounted within a vehicle including at least one hydraulic mount, each mount including a fluid chamber. A pair of accelerometers sense relative acceleration across the mount between the engine and the frame and generate a relative acceleration signal. A control unit is electrically connected to the accelerometers. The control unit is adapted to generate an electronic control signal in response to the relative acceleration signal. The control device is responsive to the electric control signal for controlling the damping force of the hydraulic mount. A control algorithm calibrates the control unit such that maximum vibration damping occurs at and around the engine resonance bounce frequency.

Control of magnetorheological engine mount

A system and method for unified vehicle dynamics control is described. A method for determining vehicle dynamics data, determining a vehicle dynamics reference model having at least one reference model parameter, and providing the reference model parameter to a closed-loop sliding mode control system is provided. A sliding mode control system substantially maintains the state of reference model parameters based on the vehicle dynamics reference model and the vehicle dynamics data. A method and system is directed to a computer readable medium containing a computer program comprising computer readable code for determining vehicle dynamics data, determining a vehicle dynamics reference model having at least one reference model parameter, and providing the reference model parameter to a closed-loop sliding mode control system.
