Claim 14:
15. A method of controlling a brake system, the method comprising:
preprocessing, by a data preprocessor, raw data including a rotation speed, a temperature and a pressure of a brake disc of the brake system to validate the raw data;
generating, by a derivative parameter preprocessor, derivative parameters from basic parameters, as output by the data preprocessor, including the rotation speed, the temperature and the pressure of the brake disc; and
generating, by a metamodel processor, a metamodel for friction coefficient prediction by performing machine learning according to the derivative parameters output by the derivative parameter preprocessor,
determining, by a brake controller, a target brake torque according to a friction coefficient output by the metamodel for friction coefficient prediction and applying a hydraulic brake pressure control signal corresponding to the determined target brake torque to the brake system,
wherein the derivative parameter preprocessor is configured to define the derivative parameters as principal factors influencing a change in a friction coefficient by analyzing relations between the basic parameters and the friction coefficient at a point in time when a friction coefficient difference occurs under an identical condition of each of the basic parameters preprocessed by the data preprocessor.
