Patent ID: 7717409

Claim:
An active vibration isolating support apparatus for suppressing a vibration transmitted to a vehicle body, comprising: active mounts which elastically support a load of an engine in the vehicle body, each of which includes an actuator; and a control unit which drives the actuator to extend and contract periodically in response to a waveform of the vibration of the engine so that an excitation plate fixed to the actuator is moved up and down; wherein when a signal to specify an initially injected cylinder is received from an engine ECU, the control unit also supplies a predetermined current to and drives the actuator based on a starting control condition so that the excitation plate is moved to an initial position which is lower than a position of the excitation plate at the time of no power supply, and starts a control of the actuator based on a control instruction value of a current in response to the vibration of the engine after the engine has started.
