An automatic train control system 501 has a vehicle characteristics learning unit 505 that learns vehicle characteristics based on the train speed and a braking command and estimated using a unit 507. An adoption judgment unit 508 determined whether the characteristics should be adopted in a braking command, and an adoption unit 509 adopts the characteristics in a braking command only if judgment unit 508 determines that the characteristics should be adopted. Judgment unit 508 may adjust the measured deceleration and shift it on a time axis to correct for vehicle characteristics, and may determine whether to adopt characteristics according to how often the measured or commanded deceleration is zero or negative, corresponding to wheel slide or rapid release and reapplication of the brake. The system may avoid learning characteristics during wheel slide or other abnormal situations that may not be obviously abnormal or impossible, avoiding capturing inaccurate performance data.
