SAE J2735-Draft-Rev18 [issued: 06-26-07]
-
78 -
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.
7.14 Data Element: DE_DMonth
Use: The DSRC style month is a simple value consisting of integer values from one to 12 representing the
month within a year. The value of 15 SHALL represent an unknown value. The range 13 to 14 and the
value zero are all reserved.
ASN.1 Representation:
DMonth ::= INTEGER (0..15) -- units of months
XML Representation:
<xs:simpleType name="DMonth" >
<xs:annotation>
<xs:documentation>
units of months
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:unsignedByte">
<xs:maxInclusive value="15"/>
</xs:restriction>
</xs:simpleType>
Used by: This entry is directly used by the following 6 other data structures in this standard (record type,
descriptive name, ASN.1, and XML name (if present) of each):
DF
<XML>, and
DF

DF

In addition, this item may be used by data structures in other ITS standards.
7.15 Data Element: DE_DrivenLineOffset
Use: The DrivenLineOffset is an integer value expressing the perpendicular offset from a reference lane
number that a computed lane is offset from. The units are a signed value with an LSB of TBD (say 10
cm?, this would allow a distance of only 12 meters offset away in either direction, seems short to me. Need
to debate this) Original proposal has 1 cm, so only 1.27 meter away, way to short. Even is we "start" from
the lane edge, this is too short.
ASN.1 Representation:
DrivenLineOffset ::= INTEGER (0..255) -- this may need to be 2 bytes
XML Representation:
<xs:simpleType name="DrivenLineOffset" >
<xs:annotation>
<xs:documentation>
this may need to be 2 bytes
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:unsignedByte"/>
</xs:simpleType>
Used by: This entry is used directly by one other data structure in this standard, a DF called
DF_ComputedLane <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
