Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_ConfidenceSet <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
7.130 Data Element: DE_ThrottlePosition
Use: The position of the throttle in the vehicle, expressed in units of 0.5 percent of range of travel,
unsigned.
ASN.1 Representation:
ThrottlePosition ::= INTEGER (0..200) -- LSB units are 0.5 percent
XML Representation:
<xs:simpleType name="ThrottlePosition" >
<xs:annotation>
<xs:documentation>
LSB units are 0.5 percent

<xs:maxInclusive value="200"/>
</xs:restriction>
</xs:simpleType>
In addition, this item may be used by data structures in other ITS standards.
Remarks: Used in some blobs.
7.131 Data Element: DE_TimeConfidence
Use: This DE is used to provide to listeners the confidence interval of the 95% confidence level for the
currently reported value of time, taking into account the current calibration and precision of the sensor(s)
used to measure and/or calculate the value. This data element is only to provide the listener with
information on the limitations of the sensing system; not to support any type of automatic error correction
or to imply a guaranteed maximum error. This data element should not be used for fault detection or
diagnosis, but if a vehicle is able to detect a fault, the confidence interval should be increased accordingly.
ASN.1 Representation:
TimeConfidence ::= ENUMERATED {
notEquipped (0), -- Not Equipped
time-100-000 (1), -- Better then 100 Seconds
time-050-000 (2), -- Better then 50 Seconds
