1. An electrically controlled braking system comprising:

  • a first control unit;

    a second control unit;

    wherein said first control unit and said second control unit are in electrical communication via a communication link;

    a human machine-interface manipulatable by a vehicle operator, said human-machine interface comprising a first sensor and a second sensor, the first sensor providing an input signal to said first control unit, and the second sensor providing an input signal to said second control unit;

    wherein said first control unit and said second control unit compare the input signal received from the first sensor with the input signal received from the second sensor, and generate control signals at least in part based upon the input signal received from the first sensor, the input signal received from the second sensor, and the comparison of the input signal received from the first sensor with the input signal received from the second sensora first brake component responsive to the control signals generated by said first control unit and said second control unit;

    a second brake component responsive to the control signals generated by said first control unit and said second control unit;

    a first control network electrically connecting said first control unit and said first brake component, said first control network adapted to transmit the control signals from said first control unit to said first brake component;

    a second control network electrically connecting said second control unit and said second brake component, said second control network adapted to transmit the control signals from said second control unit to said second brake component; and

    an auxiliary control link electrically connecting said first brake component and said second brake component, said auxiliary control link adapted to transmit the control signals between said first brake component and said second brake component when a failure occurs in one of said first control network or said second control network.
