An electronic brake system for road vehicles includes a decentrally formed electronic device and at least one central module. The central module includes at least one microprocessor with its individual intelligence. A module (1, 2, 3, 4) is coordinated in each case to a respective wheel. The modules (1, 2, 3, 4) also include microprocessors with an individual intelligence function. The wheel modules are hierarchically subordinated to the central module (5, 6). The central module (5, 6) is integrated system-wide into the remaining vehicle electronics. This means that the central module (5, 6) receives signals such as steering angle, vehicle deceleration, values delivered imposed by the driver such as brake requirement, parking brake, retarder, etc. which are of importance for the entire vehicle. The wheel modules (1, 2, 3, 4) are responsible primarily for the supply and the operational control of the in each case respective wheel. The wheel modules (1, 2, 3, 4) include amongst other things the respective power stage (35), which controls the brake-pressure modulator (29) of the respective brake cylinder (30). The wheel modules ( 1, 2, 3, 4) include the electronic devices belonging in addition to the respective wheel such as, for example, an antilock control channel coordinated to the wheel.
