ISO/TC 22/SC 32/WG 12 - Software update

This document describes use cases and activities for updating software in vehicles over the air using mobile cellular network. This document provides a case study on the use of International Standards in preparing software update packages, managing infrastructure and operation within the vehicles. This document includes descriptions of a reference model for software update operations and metadata which can be used during the software update operations.

This document specifies requirements and recommendations for software update engineering for road vehicles on both the organizational and the project level. This document is applicable to road vehicles whose software can be updated. The requirements and recommendations in this document apply to vehicles, vehicle systems, ECUs, infrastructure, and the assembly and deployment of software update packages after the initial development. This document is applicable to organizations involved in software update engineering for road vehicles. Such organizations can include vehicle manufacturers, suppliers, and their subsidiaries or partners. This document establishes a common understanding for communicating and managing activities and responsibilities among organizations and related parties. The development of software for vehicle functions, except for software update engineering, is outside the scope of this document. Finally, this document does not prescribe specific technologies or solutions for software update engineering.

This document will provide guidance on how to determine the relevant vehicle configuration information for software update engineering, according to ISO 24089:2023. This guidance will contain definitions of elements of vehicle configuration information, relationships between such elements, and examples of usage. ■ Out of Scope: • Formats for elements of vehicle configuration information. • How such information can be collected, stored, and exchanged.
