This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
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
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 <ASN>
<XML>. In addition, this item may be used by data structures in other ITS standards.
