Beschreibung
Zusammenfassung:	A safety redundant drive by wire system includes a plurality of first control members to which control signals may be communicated and a plurality of device controllers adapted to deliver control signals to a respective first control member. At least one sensor is coupled to each first control member for sensing a parameter of the first control member and responsively generating a sensor signal. Each device controller includes a first microprocessor for communicating control signals to the first control member and all other device controllers. Each device controller further includes a second microprocessor for redundantly communicating control signals to all other device controllers and for communicating with the first microprocessor. Each device controller is adapted to receive sensor signals and provide these sensor signals to the first and second microprocessors. The system includes a dual redundant communication channel system having a first communication channel controlled by the first microprocessor of each device controller and a second communication channel controlled by the second microprocessor of each device controller.
