Abstract
A system includes a first brake actuator for controlling pressure applied to a first brake, a BCU configured to receive a first plurality of inputs and to output a first BCU control signal for controlling the first brake actuator based on the first plurality of inputs, and a first switch coupled between the first brake actuator and the BCU. The system also includes a backup controller designed to receive a second plurality of inputs, determine a first backup control signal for controlling the first brake actuator based on the second plurality of inputs, determine that the BCU is functioning improperly based on the second plurality of inputs, and control the first switch to prevent the first BCU control signal from controlling the first brake actuator and to output the first backup control signal to the first brake actuator in response to determining that the BCU is functioning improperly.
