Abstract

A disturbance cancellation and generation seat system includes a seat mounted to a structure of a vehicle. The seat is accelerated due to a disturbance acceleration received in the structure and transferred to the seat. A seat control unit generates a force cancellation command signal. An actuation device is connected to the structure and is in communication with the seat control unit. The actuation device in response to receipt of the force cancellation command signal induces a cancellation acceleration motion into the seat which is equal but opposite to and therefore cancels an acceleration motion of the seat induced by the disturbance acceleration.
