ISO 23239-1:2021 pdf free download – Road vehicles一Vehicle domain service (VDS)一 Part 1: General information and use case definitions.
The connected vehicles are expected to expand and become even more popular in the markets of different countries. A variety of technologies are being developed and discussed for many applications.
Everyone who drives a car collects traffic information to determine the correct driving behaviour and accurately recognize the relevant traffic information and driving conditions without delay. Although the autonomous driving function takes over the driver’s operation, there is the same value in a judgment of correct driving behaviour. While many independent autonomous driving cars and intelligent driver assistance functions provide information collected by various sensors, LIDAR and radar, their performance is limited and the inaccuracies increase with ambient conditions such as weather and blind spots.
In addition, the blinkers normally equipped with all vehicles only provide one-way fragmentary information, though. If the vehicle communicates with other neighbouring vehicles or traffic participants and exchanges various information, it will be able to go beyond the limits of its sensor capabilities and blind spots to provide a more accurate assessment of the traffic situation. It will also be possible to negotiate planned driving manoeuvres with neighbouring vehicles and to coordinate the sequence and timing of driving manoeuvres.
This ability to share information between vehicles defined in this document is provided only on a direct communication network between the vehicle and neighbouring traffic participants. It will be accomplished with on-board functionality without investing in a significant communication infrastructure on the road. This will enable vehicles to make more accurate and appropriate driving choices, which will provide a number of benefits such as reducing traffic accidents and congestion with improving traffic efficiency.
An important aspect of this documentation development is focusing on implementation points throughout the vehicle. Typical use cases are collected, from which distinctive aspects of the implementation specification are derived. And beyond simple information exchange, the resulting information is reviewed, evaluated, and then used to generate reliable information that can be applied to critical vehicle controls.
The ISO 23239 series is developed within a unique standard number, so that it will eliminate inconsistencies and redundancies within the documentation. As a result of these tasks, compatibility and interoperability will be confirmed, being added the economy and efficiency of implementation with global consistency. Furthermore, by providing a concrete path from existing simple and partial communication interface to trusted vehicle implementation, it is expected to support a smooth launch of brand-new vehicle application and accelerate the introduction of next generation communication technologies into the future vehicle market.
