Abstract
An electrically powered suspension systemachieves vibration control of a vehicle without disturbing a vehicle behavior and impairing riding comfort even if an electric motorof an electromagnetic actuatorgenerates excessive heat, wherein the electromagnetic actuatorincludes the electric motorgenerating a driving force for vibration damping and extension/contraction; a target damping force setting partsetting a target damping force; a target extension/contraction setting partsetting a target extension/contraction force; and a drive controllerperforming the drive control of the electric motorusing a drive force based on the target damping force and target extension/contraction force by limiting the motor current not to exceed a current threshold that is an addition of a damping current threshold and extension/contraction current threshold, which thresholds are separately configured considering a priority of riding comfort and steering stability.
