The Self-energising Electro-Hydraulic Brake (SEHB) was originally developed for railway applications. Based on the same principle, a concept for road vehicles has been developed at the IFAS of RWTH Aachen University. In a first step, this paper discusses a possible braking system for passenger cars, using the self-energising concept. It meets the requirements of a braking system with capabilities for hybrid vehicles. The SEHB allows independent operation from the combustion engine and a hydraulic feedback of the braking torque facilitates electronically controlled brake blending. A design study for commercial vehicles shows the compact design of a SEHB calliper for a very high brake torque as it is needed for the powered axle of an articulated lorry. From the aspect of security a fall back level operating without electricity is needed. Even for this case the brake torque control can be ensured by a hydro-mechanical control. As published in previous papers, this functionality can be realised by a purely hydraulic control.
