In this paper, the design and construction of a prototype Steer-by-Wire vehicle is described. The prototype vehicle has been built with fault tolerant X-by-Wire systems using a time triggered architecture. The Steer-by-Wire system consists of an electric rack actuator and electric feedback actuator. One of the main issues in the development by-Wire systems is its electronics based nature and consequently the difficulty to test and verify to such an extent that the results are sufficiently convincing that the complete system is working properly. Attention was paid to the design process, which was based on the V-model. This model allows for a development approach which is traceable and verifiable to such an extent that its proper and safe working can be proven more easily.
