Electrification of vehicles and increasing level of automation of the driving task are driving factors for true by-wire technologies – braking being on of the domains where conventional mechanical fallbacks are to be replaced with electronic redundancy. The paper will define and motivate these technologies. It will furthermore discuss the concept of an electric brake pedal as a building block for true brake-by-wire. The electric brake pedal will be discussed as a component but also its integration in a redundant brake system will be presented.
While electro-mechanic brake actuators are already seen on the roadmap of brake-by wire systems, electro-hydraulic brake systems are a near-term solution and share key features of the true by-wire technology. The paper will present architectures of such electro-hydraulic brake systems consisting of separate brake control units as well as integrated solutions.
