System and Method for Controlling a Vehicle Parking Brake

A system for controlling a parking brake in a vehicle includes an operator interface configured to receive inputs from an operator of the vehicle including a first input requesting that the parking brake transition from an applied state to a released state. The system further includes a brake controller configured to identify a condition in which the parking brake should remain in the applied state. The controller generates, in the absence of the condition, a brake control signal responsive to the first input configured to cause the parking brake to transition from the applied state to the released state and transmits the brake control signal to an electromechanical valve configured to control delivery of fluid pressure to the parking brake. The controller disregards, in the presence of the condition, the first input unless the operator enters an override code comprising a predetermined sequence of inputs through the operator interface.
