This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
Remarks: Provided by VII POC-A team.
7.135 Data Element: DE_ThrottleConfidence
Use: This DE is used to provide to listeners the confidence interval of the 95% confidence level for the
currently reported value of DE_Throttle, 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:
ThrottleConfidence ::= ENUMERATED {
notEquipped (0), -- B'00 Not Equipped
prec10percent (1), -- B'01 10 percent
prec1percent (2), -- B'10 1 percent
prec0-5percent (3) -- B'11 0.5 percent
}
-- Encoded as a 2 bit value

unsigned.
