PROBLEM TO BE SOLVED: To form a brake value generator having totallized additive redundancy in such a way that control functions for additive redundancy are included herein. SOLUTION: Pressure mechanically generated from a brake value generator 1 is added to pressure electrically generated from a brake value modulator 3, and total pressure becomes brake pressure applied to a brake cylinder 12. At the time of electronic failure, pressure mechanically generated from the brake value generator 1 is automatically set effective as brake pressure, and this becomes redundant pressure. An adding device is provided in the brake value generator 1 itself, and in the adding device, the mechanically generated pressure is totallized with the pressure electrically generated from the brake value modulator 3. |
