PURPOSE: To obtain selective cutoff possibility for a partial device by providing wheel and center modules equipped with microcomputers in an electronic device, and receiving a brake pressure target value from the center module by the wheel module via a data bus, to transmit various measured values to the center module. CONSTITUTION: A brake device is composed of center and wheel modules 5, 6, and 1-4, and the value of the position of a brake pedal is dected by an electronic brake value transmitter 18, to be sent together with the position of a parking brake 19 to the module 5 and 6. The rotation frequency of an attached wheel 31 is sent to a microcomputer 28 via a lead wire 34 by a sensor 32, to measure braking pressure in a brake cylinder 30 by a pressure sensor 33. A pressure medium 6 for braking is sent to the cylinder 30 via a brake pressure modulator 29. The center and wheel modules 5, 6, and 1-4 are connected in data buses 7 and 8 to transmit these data to the center modules 5 and 6. |
