Disturbance cancellation and generation seat

A method for cancelling disturbance accelerations in a vehicle seat, comprising:

• measuring a disturbance acceleration acting to accelerate a seat mounted to a structure of a vehicle, wherein the disturbance acceleration defines multiple acceleration values each defining a transmission shift event;
• generating a force cancellation command signal in a seat control unit;
• connecting an actuation device to the structure and in communication with the seat control unit to receive the force cancellation command signal;
• and
• inducing a cancellation acceleration motion into the seat by operation of the actuation device in response to the force cancellation signal which is equal but opposite to and therefore cancels an acceleration motion of the seat induced by the disturbance acceleration.

A disturbance cancellation and generation seat system, comprising:

• a seat mounted to a structure of a vehicle, the seat accelerated due to a disturbance acceleration received in the structure and transferred to the seat, wherein the disturbance acceleration defines multiple acceleration values each defining a transmission shift event;
• a force sensor connected to the seat generating a force signal corresponding to a weight of an occupant of the seat;
• a seat control unit converting the weight of the occupant to a mass of the occupant;
• a vehicle control unit receiving data from multiple vehicle sensors including acceleration sensors, speed sensors and ambient condition sensors and forwarding the data to the seat control unit;
• and
• an actuation device connected to the structure and in communication with the seat control unit, the actuation device in response to receipt of a force cancellation command signal generated by the seat control unit inducing 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.
