As part of the continuous development of the car, the implementation of “by-wire” solutions provides vehicle manufacturers with advantages such as weight savings, simplified modular assembly and test, and increased flexibility of physical placement. In Electro-Mechanical Braking, a type of “Brake-by-Wire”, the hydraulic control structure is replaced by electronic control units, linked to electromechanical actuators, to provide reliable and fault tolerant foundation braking of the vehicle In an effort to provide timely and effective semiconductor system solutions to our customers, Motorola Semiconductor Product Sector's Advanced Vehicle Systems Architecture group has carried out a study into the specialized requirements of EMB over the past two years. Analysis of these requirements led to the development of an architecture which used new cost-effective approaches to the problem of implementing fault tolerance.
