Abstract
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. 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. 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.
