This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
7.129 Data Element: DE_SteeringWheelAngle
Use: The angle of the steering wheel, expressed in a signed (to the right being positive) value with units of
0.02 degrees.
ASN.1 Representation:
SteeringWheelAngle ::= INTEGER (-32767..32768)
-- LSB units of 0.02 degrees.
-- a range of 655.36 degrees each way
-- (1.82 full rotations in either direction)
XML Representation:
<xs:simpleType name="SteeringWheelAngle" >

Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleStatus <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
7.130 Data Element: DE_SunSensor
Use: The "Sun Sensor" Probe Data Element is intended to inform Probe Data Users as to the level of Sun
Light in the area the vehicle was traveling at the time the Probe Data snapshot was taken. The value of the
Sun Sensor data element ranges from 0-7, with 0 indicating "Complete Darkness", 1 indicating "Minimal
Sun Light", and 7 indicating "Maximum Sun Light". This information could be sent to vehicles
approaching the area to tell drives to be prepared for sunny/clouding conditions ahead or a Weather Server
for monitoring weather conditions in the area.
ASN.1 Representation:
SunSensor ::= INTEGER (0..1000) -- units of watts / m2
-- Note that units are still TBD,
-- perhasps a log scale is wanted here
XML Representation:
<xs:simpleType name="SunSensor" >

DF_VehicleStatus <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
Remarks: It is recommended that Automotive Manufacturers divide the range of their Sun Sensors into 8
resistance ranges corresponding to the above scale. For Example: a sensor that has a resistance range from
