This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
7.33 Data Element: DE_DOffset
Use: The DSRC style (time zone) offset is a simple value consisting of a signed integer representing an
hour and minute value set from -14:00 to +14:00 representing all the worlds local time zones in units of
minutes. The value of zero (00:00) may represent an unknown value. Note some time zones are do not
align to hourly boundaries.
ASN.1 Representation:
DOffset ::= INTEGER (-340..340) -- units of minutes from UTC time
XML Representation:
<xs:simpleType name="DOffset" >
<xs:annotation>
<xs:documentation>
units of minutes from UTC time
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:short">
<xs:minInclusive value="-340"/>
<xs:maxInclusive value="340"/>
</xs:restriction>
</xs:simpleType>
In addition, this item may be used by data structures in other ITS standards.
7.34 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 measurement is taken from the reference lane center line
to the new center line, independent of any width values. The units are a signed value with an LSB of 1 cm.
ASN.1 Representation:
DrivenLineOffset ::= INTEGER (-32767..32767)
-- LSB units are 1 cm.
XML Representation:
<xs:simpleType name="DrivenLineOffset" >
<xs:annotation>
<xs:documentation>
LSB units are 1 cm.
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:short">
<xs:minInclusive value="-32767"/>
</xs:restriction>
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleComputedLane <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
7.35 Data Element: DE_DrivingWheelAngle
Use: The angle of the front (steering) wheel, expressed in a signed (to the right being positive) value with
units of 0.3333 degrees and a range of plus or minus 42.33 degrees. The value of zero shall be when both
wheels are pointed such as to drive the vehicle in a straight ahead direction (the tow-in angle of each side
being equal and canceling each other out). A value of zero shall be sent when unknown.
ASN.1 Representation:
DrivingWheelAngle ::= INTEGER (-127..127)
-- LSB units of 0.3333 degrees.
-- a range of 42.33 degrees each way
