Abstract:
A system for improving the response of a vehicle to sensed condition comprising:at least one sensor, mounted in the vehicle, for generating successive first and second ambient vibration signals corresponding to first and second sensed conditions;at least one actuator, mounted on the vehicle, for generating an actuator force that is applied to the vehicle;a data module coupled to the sensor and the actuator for storing data, correlating at least one actuator force with at least one sensor response to the force;a control circuit, including a Kalman filter, for receiving the first and second ambient vibration signals in succession from the sensor and receiving the stored data from the data module, and transmitting a first control signal to an associated actuator corresponding to the first ambient vibration signal;wherein the control circuit utilizes Kalman filtering and a covariance value, that is a function of an actuator force, to modify data in the data module; andthe control circuit transmits a second control signal that is a function of the second ambient vibration signal and the modified data of the data module.
