Apparatus for controlling electro-mechanical braking system and method thereof

A method of controlling an electro-mechanical braking system comprising a first braking control module, a second braking control module, a first power module configured to supply power to the first braking control module, a second power module configured to supply power to the second braking control module, and an integrated switch, the method comprising:

• receiving, by the first braking control module, an electronic parking brake (EPB) switch signal, a braking control signal, and a cylinder pressure value, and receiving, by the second braking control module, a brake pedal signal, the braking control signal, and the cylinder pressure value;
• driving, by the first braking control module, a parking brake and an additional braking valve according to an input signal, and driving, by the second braking control module, a braking motor and a main braking valve according to an input signal;
• receiving, by the first brake control module and the second braking control module, a failure signal;
• when the failure signal corresponds to an open-circuit failure that occurs in any one of the first power module and the second power module, turning the integrated switch on to integrate output powers of the first power module and the second power module;
• and
• when the failure signal corresponds to a short-circuit failure that occurs in any one of the first power module and the second power module, turning the integrated switch off to separate the output powers.

An apparatus for controlling an electro-mechanical braking system, the apparatus comprising:

• a first braking control module configured to receive at least one of an electronic parking brake (EPB) switch signal, a braking control signal, or a cylinder pressure value and to operate a parking brake and an additional braking valve;
• a second braking control module configured to receive at least one of a brake pedal signal, the braking control signal, or the cylinder pressure value and to operate a braking motor and a main braking valve;
• a first power module configured to supply power to the first braking control module;
• a second power module configured to supply power to the second braking control module;
• an integrated switch switched under control of the first braking control module or the second braking control module and configured to integrate output powers of the first power module and the second power module;
• and
• a connection bus configured to transfer transmission and reception signals between the first braking control module and the second braking control module,
• wherein the first braking control module and the second braking control module are configured to selectively turn the integrated switch on or off depending on a type of failure detected in either the first power module or the second power module.
