Choosing one supplier for the Basic Software of all ECUs benefits both Audi developers and ECU manufacturers: It reduces integration and testing effort and shortens development times, the contract winners said in a press release.

Vector's BSW modules comply with Autosar specification 3.1, they offer efficient implementation and are adapted to VW Group requirements in the diagnostics area. Modules for end-to-end protection (E2E) by TTTech Automotive are integrated seamlessly in function and configuration. This makes the solution usable for safety-related applications according to the safety standard ISO 26262 ASIL-D. Other factors playing a role in Audi's decision were the highly efficient configuration of communication parameters and Vector's worldwide services.

Tier ones can supplement this core functionality of the BSW by adding further Vector modules. Examples are Autosar operating system, system and memory services, communication modules for Ethernet and MOST, Flash Bootloader and microcontroller abstraction layers (MCALs) for various hardware platforms. This gives them a uniform solution for the complete Autosar BSW, which can also be used for other automotive OEMs. Since the configuration concept for the entire stack is consistent it simplifies the work of software developers at the ECU manufacturer and improves the quality of the whole ECU software, Vector claims.
