Braking system having switching device for supplying energy to electrically controlled brake through brake controller upon operation of brake operating member

摘要

An electrically controlled braking system includes (i) an electrically controlled brake, (10, 12, 14, 16, 33, 34) for braking a wheel (FL, FR, RL, RR) of an automotive vehicle, (ii) an electric power source device (312, 314, 316), and (iii) a brake control apparatus (18) for controlling an electric energy to be supplied from said electric power source device to said brake, for thereby controlling an operation of said brake. In the braking system the brake control apparatus (18) is sectioned into at least three control groups (44, 302, 46, 304, 48, 50, 52, 306) each of which is principally constituted by a computer; and the electric power source device is sectioned into at least three source groups (312, 314, 316) each of which includes at least one electric power source such that the electric energy is supplied to each of said at least three control groups of said control apparatus from a corresponding one of said at least three source groups of said electric power source device.
