Drive-by-wire applications, such as brake-by-wire, steer-by-wire and throttle-by-wire, are becoming increasingly popular in the automotive industry. This work examines different sensors for driver-input systems for drive-by-wire, as well as the integration of these sensors to achieve the fault-tolerance necessary for such safety-critical applications. A pedal test bed is constructed for studying the integration of similar and dissimilar sensors. Two sensor integration topologies involving multiple sensors, similar and dissimilar, are proposed to demonstrate different possibilities of fault-tolerant systems. The merits and limitations of both systems when coping with sensor and mechanical faults and failures are presented.
