Road vehicles — Ergonomic aspects of human vehicle interactions — Taxonomy for the classification of adaptive interactive vehicle systems
This document provides a taxonomy to classify the type of adaptivity within vehicle systems. The taxonomy includes five types ranging from no adaptation (type 0) to adaptations based on interpreted user characteristics and context data (type 4). This document provides definitions of the five types of adaptation and explains adaptation in a consistent and coherent manner. By offering definitions and descriptions of the five types, this document can be used to classify the adaptivity within vehicle systems according to the types. This document is intended to be applied to all components of vehicle systems that the driver and/or other occupants interact with either while driving or while parked. This includes vehicle information systems, communication systems, for example, navigation systems or mobile devices connected to the vehicle infrastructure, traffic and travel information (TTI) systems, as well as vehicle comfort systems, for example, climate control, massage, or ambient lighting. The taxonomy is also applicable to third-party software provided by third-party suppliers that is displayed and/or operated in the vehicle. The taxonomy can also be applied to interactive exterior elements, like windscreen wipers or pedestrian communication devices and non-driving-related functions that are novel to future vehicles in the context of automated driving, such as playing a video. The information and communication vehicle systems described in this document exclude driving-operation or driving-assistance systems. Consequently, safety-related functions governed by Automotive Safety Integrity Level (ASIL) specifications (ISO 26262) are not addressed. Implementation and validation of data collection/detection are also beyond the scope. Additionally, priority handling, as well as varying legal regulations across countries, are not covered in the taxonomy.

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).

Introduction
With increasing technical feasibility of artificial intelligence (AI), more companies are integrating AI-based
adaptivity and personalization into vehicle systems to adapt their behavior and/or content to the needs
or expectations of individual users or groups of users. This enables vehicle systems to match individual
user preferences and assist and ease execution of non-driving related functions. For the driving context,
this offers the potential to reduce workload and distraction by helping users to handle large amounts of
information within road vehicles. Nevertheless, there is no uniform classification for the capacities and
characteristics of the type of adaptivity for vehicle systems.
This may lead to several risks of misunderstandings and unmatched expectations for different stakeholders
as well as for the end user. If the type of the adaptivity is not clear to the end user, it can lead to uncertainty
and a lack of transparency, predictability, algorithmic awareness, and understanding of the vehicle
system’s capacities and limits. Developers as well as the manufacturers as stakeholders also bear the
risks of misunderstandings or unmatched expectations within all phases of the development process
(ISO/IEC/IEEE 29148).
The ISO 8235 was developed to classify vehicle functions regarding their type of adaptivity and parameters
used to achieve the adaptations.
Standardizing the types of adaptation of vehicle systems serves the following purposes:
a) enables end users to assess the extent and limitations of adaptation specified by the manufacturers,
suppliers and researchers,
b) provides an unambiguous framework for the specification of adaptive vehicle systems and the technical
differentiation of the respective types of adaptivity in the requirement phase,
c) provides clarity and transparency in communication on the topic of adaptive vehicle systems for
manufacturers, suppliers as well as researchers,
d) reduces uncertainty about the capacity and limitations associated with non-transparent black box
technology solutions for the manufacturers,
e) prevents misunderstandings and deviating expectations between development partners of adaptive
vehicle systems and therefore,
f) prevents unnecessary effort, duplicate work and costs in the development and evaluation of adaptive
vehicle systems.

1 Scope
This document provides a taxonomy to classify the type of adaptivity within vehicle systems. The
taxonomy includes five types ranging from no adaptation (type 0) to adaptations based on interpreted user
characteristics and context data (type 4). This document provides definitions of the five types of adaptation
and explains adaptation in a consistent and coherent manner. By offering definitions and descriptions of the
five types, this document can be used to classify the adaptivity within vehicle systems according to the types.
This document is intended to be applied to all components of vehicle systems that the driver and/or other
occupants interact with either while driving or while parked. This includes vehicle information systems,
communication systems, for example, navigation systems or mobile devices connected to the vehicle
infrastructure, traffic and travel information (TTI) systems, as well as vehicle comfort systems, for example,
climate control, massage, or ambient lighting. The taxonomy is also applicable to third-party software
provided by third-party suppliers that is displayed and/or operated in the vehicle.
The taxonomy can also be applied to interactive exterior elements, like windscreen wipers or pedestrian
communication devices and non-driving-related functions that are novel to future vehicles in the context of
automated driving, such as playing a video.
The information and communication vehicle systems described in this document exclude driving-operation
or driving-assistance systems. Consequently, safety-related functions governed by Automotive Safety
Integrity Level (ASIL) specifications (ISO 26262) are not addressed. Implementation and validation of data
collection/detection are also beyond the scope. Additionally, priority handling, as well as varying legal
regulations across countries, are not covered in the taxonomy.
