In addition, this item may be used by data structures in other ITS standards.
7.128 Data Element: DE_SteeringWheelAngleRateOfChange
Use: The rate of change of the angle of the steering wheel, expressed in signed units of 3 degrees/second
over a range of 381degrees in either direction. To the right being positive.
ASN.1 Representation:
SteeringWheelAngleRateOfChange ::= INTEGER (-127..127)
-- LSB is 3 degrees per second
XML Representation:

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.
Remarks: This element may be used by road maintenance operations to determine presence of an
obstruction or pothole in the roadway.
[Note: Traffic info committee proposes new values of: 4/7/06 Steering Wheel angle is defined in Degrees
with a Resolution of 1 Degree-signed, a Min Value of - 780, and a Max Value of +780. Steering Wheel
Angle Rate-of-Change is defined in Degrees per Second with a Resolution of 4 Degrees-Signed, a Min
Value of -1433, and a Max Value of +1433. ]
