Introduction and Overview of Fault Tolerant Drive by Wire Systems

A brief overview of fault tolerant drive-by-wire technology is presented in this chapter. A review of drive by wire system benefits in performance enhancements and vehicle active safety is then discussed. Challenges in relation to the fault tolerant design of drive by wire system are then presented. This is followed by in-depth coverage of fault tolerant design of a steer by wire system. Future trends in the design of fault tolerant drive by wire systems are presented at the conclusion of the chapter.
