Automotive System Integration and Testing: A Comprehensive Guide to ISO 26262 Compliance

The integration and testing phase encompasses three sub-phases and three objectives, as detailed below. The first sub-phase involves integrating the hardware and software of each element. The second sub-phase focuses on integrating the elements that constitute a system to form a complete item. The third sub-phase integrates the item with other systems within a vehicle. The overarching objectives are:

To define the integration steps and integrate the system elements until the system is fully integrated.
To verify that the defined safety measures, resulting from safety analyses at the system architectural level, are properly implemented.
To provide evidence that the integrated system elements fulfill their safety requirements according to the system architectural design.

7.2 General

The integration of the item's elements is executed in a systematic manner, beginning with software-hardware integration and verification, progressing to system integration and verification, and culminating in vehicle integration and verification. Specified integration tests are conducted at each integration stage to ensure that the integrated elements interact correctly. Following sufficient development of hardware and software in compliance with ISO 26262-5 and ISO 26262-6, system integration can commence as outlined in this clause.
