7.7 Data Element: DE_BrakeAppliedStatus
Use: A bit string enumerating the status of various brake systems (different wheels) of the vehicle. Brake applied
status indicates when vehicle braking has occurred. This may be used by traffic management centers to
determine that an incident or congestion may be present. It is possible for some vehicles to provide an indication
of how hard the braking action is but at this time only an indication that braking has occurred is used.
ASN.1 Representation:
BrakeAppliedStatus ::= BIT STRING {
allOff (0), -- B'0000 The condition All Off
leftFront (1), -- B'0001 Left Front Active
leftRear (2), -- B'0010 Left Rear Active
rightFront (4), -- B'0100 Right Front Active
rightRear (8), -- B'1000 Right Rear Active
allOn (15) -- B'1111 The condition All On
} -- to fit in 4 bits
