Audi Chooses AUTOSAR Software from Vector and TTTech Automotive

July 9, 2010

Vector, together with its strategic partner TTTech Automotive, was awarded an international supply contract by Audi for AUTOSAR Basic Software (BSW). The call for bids covered modules for communication over CAN, LIN and FlexRay, including RTE and end-to-end protection for safety-related ECUs. 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.

Vector’s solution impressed Audi technically: The 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 ISO 26262 ASIL-D. Other factors playing a role in Audi’s decision were the highly efficient configuration of communication parameters and Vector’s comprehensive worldwide services.

ECU manufacturers can supplement this core functionality of the BSW by adding other Vector modules: Operating system, system and memory services, communication over Ethernet and MOST, Flash Bootloader and 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. The consistent configuration concept for the entire stack simplifies the work of software developers at the ECU manufacturer and improves the quality of the whole ECU software.
