Abstract

PURPOSE: To complete accurately insufficiency of electric braking force with braking force of a liquid brake in the braking device of the rolling stock car by a method wherein when an electric brake becomes to invalid, output liquid pressure of an electropneumatic converter is made to zero.
CONSTITUTION: Braking commands applied to command lines 2, 3, 4 are transmitted to an electric brake equipment 13 through a D-A converter 12. The electropneumatic converter sends out a liquid having pressure corresponding to a detected value of electric brake torque to a calculating relay valve 9. While electromagnetic valves 6, 7, 8 send out liquids having pressure corresponding to the brake commands applied to the command lines 2, 3, 4 to the calculating relay valve 9. The calculating relay valve 9 sends out a liquid having pressure corresponding to insufficiency of braking force to a brake cylinder 10. When output of the electric brake becomes to zero, an electric brake invalid detector 15 makes the output of the electropneumatic converter 17 to zero to eliminate hysteresis.
