Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 33,
Vehicle dynamics and chassis components.
This third edition cancels and replaces the second edition (ISO 15037-1:2006), which has been
technically revised. The main changes compared to the previous edition are as follows:
— Recognizing regenerative braking and active control systems.
This corrected version of ISO 15037-1:2019 incorporates the following corrections:

Introduction
This document was developed to define general test conditions for vehicle dynamic tests. Any given
vehicle, together with its driver and the prevailing environment, constitutes a unique closed-loop
system. The task of evaluating the dynamic behaviour of the vehicle is therefore very difficult since
there is significant interaction between these driver-vehicle-environment elements, and each of these
elements is individually complex in itself.
The test conditions exert large influence on the test results. Only test results obtained at identical test
conditions are comparable.
INTERNATIONAL STANDARD ISO 15037-1:2019(E)
Road vehicles — Vehicle dynamics test methods —
Part 1:
General conditions for passenger cars
1 Scope
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 (X , Y , Z ) is the reference point, and this position
V V V
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.
