This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
In addition, this item may be used by data structures in other ITS standards.
6.2 Data Frame: DF_AccelSteerYawRateConfidence
Use: A single byte long data frame combining multiple related bit fields into one byte.
ASN.1 Representation:
AccelSteerYawRateConfidence ::= SEQUENCE {
yawRate YawRateConfidence,
-- 3 bits
acceleration AccelerationConfidence,
-- 3 bits
steeringWheelAngle SteeringWheelAngleConfidence
-- 2 bits
}
XML Representation:
<xs:complexType name="AccelSteerYawRateConfidence" >
<xs:sequence>
<xs:element name="yawRate" type="YawRateConfidence" />
<!-- 3 bits -->
<xs:element name="acceleration" type="AccelerationConfidence" />
<!-- 3 bits -->
<xs:element name="steeringWheelAngle" type="SteeringWheelAngleConfidence" />
<!-- 2 bits -->
</xs:sequence>
</xs:complexType>
Used by: This entry is directly used by the following 2 other data structures in this standard (record type,
descriptive name, ASN.1, and XML name (if present) of each):
DF
<XML>, and
DF
In addition, this item may be used by data structures in other ITS standards.
6.3 Data Frame: DF_Application Context Mark
Use: The Application Context Mark (ACM) provides a unique means of identifying each element of each
specific application. A priority is assigned to each ACM, allowing a single application to utilize different
priorities for different elements.
ASN.1 Representation:
AppContextMark ::= SEQUENCE {
said SpecificApplicationIdentification, -- SAID
context Context, -- see appropriate Appendix
priority Priority, -- in accordance with IEEE P1609
...
}
XML Representation:
<xs:complexType name="AppContextMark" >
<xs:sequence>
<xs:element name="said" type="SpecificApplicationIdentification" />
<!-- SAID -->
<xs:element name="context" type="Context" />
<!-- see appropriate Appendix -->
<xs:element name="priority" type="Priority" />
<!-- in accordance with IEEE P1609 -->
</xs:sequence>
</xs:complexType>
Used by: This entry is used directly by one other data structure in this standard, a DF called DF_ValueList
