Wheel slide protection devices have been installed on Shinkansen braking systems to prevent wheel flats. However, braking distance considerably increased when wheel slips frequently happened under wet conditions. This problem was caused by that braking force was excessively decreased due to slow wheel slip detection. We proposed the slip rate wheel slide control system supported by synchronized pulse processing method in order to calculate wheel speed/deceleration more accurate and to detect wheel slips more rapidly. Accuracy of speed/deceleration calculation is discussed. Those were reduced to about one-third of a conventional method. We obtained good results at running test of series E3 Shinkansen that increase of emergency braking distance was less than only 4.5% when compared with about 20% that is obtained with the conventional systems. This system is made for practical use on series E2, E3 and E4 Shinkansen vehicles.
