<p>The ride quality of a train deteriorates when brake notches are switched frequently to follow a predetermined velocity pattern with the aim to improve the stopping accuracy. This automatic train braking system comprises a means for generating a plurality of velocity patterns based on decelerations corresponding to respective brake notches, train position, a means for computing a deceleration force of the respective notches, means for computing a deceleration of a vehicle, a means for estimating disturbance based on the deceleration force and deceleration, a means for correcting a velocity pattern based on the estimated disturbance, and a notch switching means for switching to a notch corresponding to the velocity pattern when the velocity pattern corresponds with the train velocity so as to minimise disturbance. The system also enables the train to be braked to a stop at a given target position.</p> |
