TTXSafeCOM - Safe Communication for Critical Systems |
||
TTXSafeCOM is a reusable and modular safety layer that guarantees “end-to-end communication integrity” and reduces costs for application integration by using standardization and re-use. It is part of the AUTOSAR communication stack for automotive software and provides duplicate data paths starting at the place where CRC protection can no longer be applied. Automotive electronic control units (ECUs), with its increasing safety-related functions, are linkedusing bus systems such as CAN or FlexRay. System safety depends more and more on the integrity of the communication between ECUs. TTXSafeCOM ensures “end-to-end communication integrity” by checking correctness of messages between applications. By using standardization and re-use this safety layer reduces costs for application integration. Costs for application development are reduced by offering the integration of a generic standard solution to the automotive industry instead of an application-specific solution. TTXSafeCOM can be used in different ECUs for powertrain on chassis applications to provide a coherent solution for one OEM with less integration effort. Tier 1s can use this solution across families of ECUs which are used at different OEMs. TTXSafeCOM is TÜV-approved and developed according to IEC 61508 for applications up to Safety Integrity Level (SIL) 3. The solution is application-independent and useable universally. For more information, please contact products@tttech-automotive.com. |
