US 2026/0307547 A1 · VEHICLE SEAT VIBRATION SUPPRESSION DEVICE AND METHOD

Abstract

A vehicle seat vibration suppression device includes a height adjusting actuator that adjusts the height of a seat, a counteracting force determination unit that receives an excitation frequency of the seat as an input and determines a counteracting force for suppressing vibration of the seat, and a displacement command generator that determines a control displacement of the height adjusting actuator for implementing the counteracting force determined by the counteracting force determination unit and provides the result to the height adjusting actuator. The vehicle seat vibration suppression device may operate a method to cancel/reduce seat vibrations.

Dependent claims

A vehicle seat vibration suppression device comprising:

a height adjusting actuator configured to adjust a height of a seat of a vehicle;
a controller circuit configured to:
receive, from a filter of a plurality of filters of a signal processor, an excitation frequency of the seat;
and
determine, based on the excitation frequency, a counteracting force for suppressing vibration of the seat;
and
a displacement command generator configured to:
determine, based on the counteracting force, a control displacement of the height adjusting actuator for implementing the counteracting force;
and
provide the control displacement to the height adjusting actuator to cause the height adjusting actuator to adjust the height of the seat of the vehicle.
