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

The integration and testing phase comprises three sub-phases and three objectives as described below. The first sub-phase is the integration of the hardware and software of each element. The second sub-phase is the integration of the elements that comprise a system to form a complete item. The third sub-phase is the integration of the item with other systems within a vehicle. The objectives of this clause are:

• a) to define the integration steps and to integrate the system elements until the system is fully integrated;
• b) to verify that the defined safety measures, resulting from safety analyses at the system architectural level, are properly implemented;
• c) to provide evidence that the integrated system elements fulfil their safety requirements according to the system architectural design.

7.2 General

The integration of the item's elements is carried out in a systematic way starting from software-hardware integration and verification through system integration and verification to vehicle integration and verification. Specified integration tests are performed at each integration stage to provide evidence that the integrated elements interact correctly. After sufficient development of hardware and software in accordance with ISO 26262-5 and ISO 26262-6, system integration can be started in accordance with this clause.
