BRAKE CONTROL DEVICE AND BRAKE CONTROL METHOD

摘要

[Problem] When a brake is controlled on the basis of a plurality of commands, high-rank priority is secured, and a structure for slide control is simplified. [Solutions] An adjustment valve (3) adjusts a fluid supplied from a fluid source (2) in a predetermined pressure to output the adjusted fluid. An output valve (10) switches opening/closing thereof on the basis of a switching command. A slide detection part (7) detects whether a vehicle slides to inform whether the vehicle slides to a brake control unit (6). The brake control unit (6) determines a pressure of air outputted from a control valve (4) on the basis of the command of the brake and the detection result of the slide detection part to send a command to an AV solenoid valve (8) and a RV solenoid valve (9) provided in the control valve (4). When the slide detection part (7) detects the sliding, the brake control unit (6) sends a command to an exhaust valve (11) so that the air is exhausted from the exhaust valve (11). A relay valve (5) adjusts the pressure of the air supplied from the fluid source (2) on the basis of the highest pressure of the pressure of the air outputted from the output valve (10) that is controlled by the exhaust valve (11) and the pressure of the air outputted from the control valve (4) to output the adjusted pressure of the air to a brake cylinder.
