Abstract: A BCG analysis system includes a vehicle behavior sensor, a posture measurement sensor, a pattern database, a BCG measurement unit, a signal processing unit, and a biostate recognition unit. The vehicle behavior sensor measures the physical momentum of a vehicle. The posture measurement sensor measures the posture of a testee. The pattern database stores standardized representative patterns. The BCG measurement unit measures the BCG signal of the testee. The signal processing unit obtains desired data by matching the BCG signal with a pattern of the pattern database, searching the pattern database for a new pattern when the posture of the testee and the physical momentum of the vehicle may be changed, and matching the BCG signal of the BCG measurement unit with the new pattern. The biostate recognition unit recognizes the biostate of the testee.
