Introduction

Electronic control units and software of increasing complexity have become essential to the operation of road vehicles in recent years. This software is often updated to increase functionality and maintain the safety and cybersecurity of road vehicles.

Today, in-vehicle software is updated in a workshop by a skilled person or automatically over-the-air by the vehicle user. With the increased frequency of software update campaigns, it is important to have individual vehicle configuration information. Therefore, the establishment and application of software update engineering is important to ensure software quality, cybersecurity, and safety.

Software update engineering activities occur throughout the life cycle of vehicles.

This document provides terminology, objectives, requirements, and guidelines related to software update engineering as a foundation for common understanding throughout the supply chain. By applying requirements and recommendations in this document, the following benefits can be achieved for software update engineering:

— safety and cybersecurity are addressed in software update operations in road vehicles;
— establishment of processes, including goal setting, planning, auditing, process monitoring, process measurement, and process improvement;
— shared awareness of safety and cybersecurity among related parties.

Figure 1 shows the overview of this document.

Figure 1 — Overview of this document

In this document, clauses are structured using the following approach:

— each process is defined and implemented before it is executed;
— each process is established, documented and maintained.

This document describes the following activities:

— implementation of organizational level processes for software update engineering;
— implementation of software update project level processes for each software update project;
— definitions of functions for the vehicle and infrastructure to support the activities and processes of this document;
— assembly of software update packages using functions in the infrastructure;
— preparation and execution of software update campaigns using functions in the vehicle and infrastructure.
