This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
6.4 Data Frame: DF_BrakeSystemStatus
Use: A single byte long data frame combining multiple related bit fields into one byte.
ASN.1 Representation:
BrakeSystemStatus ::= SEQUENCE {
wheelBrakes BrakeAppliedStatus,
-- 4 bits
traction TractionControlState,
-- 2 bits
-- 2 bits
}
XML Representation:
<xs:complexType name="BrakeSystemStatus" >
<xs:sequence>
<xs:element name="wheelBrakes" type="BrakeAppliedStatus" />
<!-- 4 bits -->
<xs:element name="traction" type="TractionControlState" />
<!-- 2 bits -->
<xs:element name="abs" type="AntiLockBrakeStatus" />
<!-- 2 bits -->
</xs:sequence>
</xs:complexType>
Used by: This entry is directly used by the following 3 other data structures in this standard (record type, descriptive name,
ASN.1, and XML name (if present) of each):

MSG
In addition, this item may be used by data structures in other ITS standards.
6.5 Data Frame: DF_ConfidenceSet
Use: A set of various measurement confidence values about the vehicle.
ASN.1 Representation:
ConfidenceSet ::= SEQUENCE {
accelConfidence AccelSteerYawRateConfidence,
-- contains lat, long, vert, and yaw
speedConfidence SpeedandHeadingConfidence,
timeConfidence TimeConfidence,
posConfidence PositionConfidenceSet,
steerConfidence SteeringWheelAngleConfidence,
throttleConfidence ThrottleConfidence
}
XML Representation:
<xs:complexType name="ConfidenceSet" >
