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, 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, 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

This document specifies framework architecture for plug and play (PnP) functionality in vehicles and identifies the issues related to exchanging information between occupants (users) and PnP functions. The connection between PnP vehicles and occupants is established by nomadic devices and the exchanging information is bidirectional. The main purpose of architecture is to utilize the PnP vehicle information and enhance the safety state and improve the convenience of occupants in PnP vehicles by adopting various pieces of information of PnP functionality in vehicles including sensors, mechanical equipment, and communication devices.

This document covers subjects related to representation of the status of a PnP vehicle and occupant. The status of a PnP vehicle and occupant is represented as a safety state/availability state and driver information, respectively. Therefore, information exchange between a PnP vehicle and occupants is mandatory.

This system is based on the following assumptions:

• A PnP vehicle is equipped with several sensors such as radar, lidar, camera, vehicle mechanical information such as steering, acceleration/brake, ECU, and communication devices such as WLAN, Bluetooth. In addition, more sensors or devices can be extensible with the advance of technology, and a PnP vehicle can adapt these devices.
• Occupants have a nomadic device such as smart phone, or wearable which can be used to exchange information with a PnP vehicle. The health information of occupants may be delivered to a PnP vehicle.
• The major use case is to inform the status of a PnP vehicle and occupants using the information between a PnP vehicle and occupants.

1 Scope

This document defines framework architecture for plug and play (PnP) vehicles and identifies the issues related to exchanging information between occupants (users) and PnP vehicles with nomadic devices. The purpose of architecture is to enhance PnP vehicles and the occupants’ safety state by exchanging the information/availability from PnP vehicles and occupants’ information/status.

The function of frame architecture is to define message follows and its effect on safety state between a PnP vehicle and the occupants. This document specifies the framework of safety state representation between the PnP vehicle and the occupants. The state of the PnP vehicle depending on the PnP vehicle’s equipment informs the occupants, and the status of the occupants is also transmitted to the PnP vehicle where status information is delivered by nomadic devices.
