<p>A system for enhancing vibration reduction in a vehicle that utilizes one or more sensors which sense ambient vibration in the vehicle and generate a signal corresponding to the sensed vibrations. A control circuit is coupled to the sensors and receives the signals. The control circuit, utilizing Kalman filtering algorithms, generates a control signal that adapts a previous command force, from an actuator to a sensor, thereby dynamically updating a parameter that represents an estimated vehicle response. This dynamically updated parameter is a result of utilizing a covariance that is a function of an empirically derived constant value and a change in forces exerted by the actuator. The control circuit outputs this control signal to vibration generator units, which generate a vibration field for reducing vibrations in the vehicle.</p> |
