Claim 0:
1. An apparatus for determining a friction coefficient of a brake friction material, the apparatus comprising:
a model generation device configured to generate a friction coefficient meta model to determine the friction coefficient based on information of an operation state of a brake using raw data acquired through a preceding test evaluation process,
wherein the model generation device comprises:
a preprocessor configured to process the raw data to acquire data required for machine learning;
a processor configured to train a model through machine learning using data acquired by the preprocessor as training data; and
a postprocessor configured to further process the model completely trained by the machine learning unit to extract a final friction coefficient meta model to determine the friction coefficient corresponding to the operation state of the brake from an input parameter indicating the operation state of the brake; and

wherein the raw data comprises data on a rotation speed and a temperature of a brake disc or a rotor and a brake hydraulic pressure, indicating the operation state of the brake, and data on the friction coefficient corresponding to the operation state of the brake.
