A module for providing control signals for a brake system of a vehicle which has a supply source, including: at least one interface to be connected to a compressed-air source; at least one interface to transmit the control signals to at least one processing unit for the purposes of generating brake pressures; wherein the module is configured to be provided with a supply by a further supply source. Also described are a related redundancy system, an electronically controlled brake system, and a method.

An electromechanical brake assist system driven by an electric motor cooperating with a master cylinder and having, along the axis of actuation, a helper piston in the shape of an axial sleeve solidly connected with a guide bracket and having a threaded surface. A nut, fixed in translation but free to rotate, has interior threads that complement those of the helper piston, which it receives, and exterior teeth that cooperate with the drive motor. A plunger piston carries a drive base so it can be pushed by the piston. Its other extremity is connected to the control rod, formed from a body and a head. The body has a crimping area and the head has a sleeve with an extremity that can be crimped along the crimping area.
