Input parameters for the simulation tool
Introduction
This Appendix describes the list of parameters to be provided by the vehicle manufacturer as input to the simulation tool. The applicable XML schema as well as example data are available at the dedicated electronic distribution platform.
The XML is automatically generated by the air drag pre-processing tool.
Definitions
(1) ‘Parameter ID’: Unique identifier as used in the simulation tool for a specific input parameter or set of input data
(2) ‘Type’: Data type of the parameter
string … sequence of characters in ISO8859-1 encoding
token … sequence of characters in ISO8859-1 encoding, no leading/trailing whitespace
date … date and time in UTC time in the format: YYYY-MM-DD T HH:MM:SS Z with italic letters denoting fixed characters e.g. ‘2002-05-30T09:30:10Z’
integer … value with an integral data type, no leading zeros, e.g. ‘ 1800 ’
double, X … fractional number with exactly X digits after the decimal sign ( ‘ . ’ ) and no leading zeros e.g. for ‘ double, 2 ’ : ‘ 2345.67 ’ ; for ‘ double, 4 ’ : ‘ 45.6780 ’
(3) ‘Unit’ … physical unit of the parameter
