An electrically controlled braking system includes a first control unit and a second control unit in electrical communication via a communication link and a human machine-interface manipulatable by a vehicle operator. The human-machine interface includes a first sensor and a second sensor, the first sensor providing an input signal to the first control unit, and the second sensor providing an input signal to the second control unit. The first control unit and the 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 sensor.
