A park-brake monitoring-system monitors the operating state of a park-brake
system of a vehicle. The park-brake monitoring-system comprises
operating-state sensors that produce and communicate sensed
operating-state signals in manners dependent upon the operating state of
the park-brake system to other components of the vehicle. The
configuration and interaction with the park-brake system and the
park-brake monitoring system of the operating-state sensors is refined
such that the sensed operating-state signals produced thereby include
signal types that are implicative of the park-brake system having a
fully-set operating state, signal types that are implicative of the
park-brake system having a fully-released operating state, signal types
implicative of the park-brake system having a not-fully-released operating
state, and signal types implicative of the park-brake system having a
not-fully-set operating state.
