ISO 15037-1:2019 Road vehicles一Vehicle dynamics test methods – Part 1: General conditions for passenger cars.
This document specifies the general conditions that apply when vehicle dynamics properties are
determined according to ISO test methods.
In particular, it specifies general conditions for:
— variables;
— measuring equipment and data processing;
— environment (test track and wind velocity);
— test vehicle preparation (tuning and loading);
— initial driving; and
— test reports (general data and test conditions).
These items are of general significance, regardless of the specific vehicle dynamics test method. They apply when vehicle dynamics properties are determined, unless other conditions are required by the standard which is actually used for the test method.
This document is applicable to passenger cars as defined in ISO 3833 and light trucks.
NOTE The general conditions defined in existing vehicle dynamics standards are valid until a reference to this document is included.
This document is cited in many other standards without a dated reference. In the course of its revision, no change in the numbering of clauses, tables and figures is anticipated.

4 Variables
4.1 Reference system
The variables of motion used to describe vehicle behaviour in a test-specific driving situation relate to the intermediate axis system (X, Y, Z) (see ISO 8855).
The location of the origin of the vehicle axis system (Xv, Y, Z) is the reference point, and this position shall be reported (see Annex A).
NOTE Useful positions for the reference point include (1) the centre of gravity of the vehicle and (2) a fixed point of geometry such as the point in the longitudinal plane of symmetry at the height of the centre of gravity and at mid-wheelbase. Locating the reference point at the centre of gravity is very useful for analytical evaluation of the test results of individual vehicles, but can cause difficulty in comparing results for different vehicles. Locating the reference point at the geometrical position is more convenient for comparing results from different tests, but can complicate theoretical analysis.
4.2 Variables to be determined
To describe the vehicle dynamics in terms of driver input and vehicle response, the principal relevant variables are the following.ISO 15037-1 pdf download.
