Abstract
Systems and methods for shut off valve failure detection are provided. The system may comprise a housing, a shut off valve disposed within the housing, a first servovalve and a second servovalve coupled to the housing, and a pressure sensor disposed within the housing in fluid communication with the shut off valve. A controller may receive a pressure signal from the pressure sensor in the system, and a brake signal from a brake input device. The controller may determine whether there has been a shut off valve failure in the system in response to the pressure signal being greater than a pressure threshold and the controller failing to receive the brake signal, for a threshold period. The controller may then send a signal to a notification system in response to detection of the shut off valve failure and output a shut off valve failure notification.
