ISO 26262 Part 1 – Vocabulary and Key Terminology Explained Hello, automotive engineers and functional safety enthusiasts! Welcome to the first deep-dive post in our comprehensive ISO 26262 series at PiEmbSysTech. In this article, we will thoroughly explore ISO 26262 Part 1 – Vocabulary, which defines all the terms, definitions, and abbreviations that are used throughout the entire 12-part…

AUTOSAR E2E Profile 22: The Definitive Technical Guide to SOME/IP Event Safety Communication Protection AUTOSAR E2E Profile 22 is the purpose-built End-to-End safety communication protocol for SOME/IP events in Automotive Ethernet service-oriented architectures – the event-driven counterpart to Profile 6, which protects SOME/IP data elements. While Profile 6 assumes a continuous sender-receiver…

AUTOSAR E2E Profile 11: The Definitive Technical Guide to Compact LIN Safety Communication Protection AUTOSAR E2E Profile 11 is the purpose-built End-to-End safety communication protocol for the Local Interconnect Network (LIN) bus – the low-cost, single-master serial bus that remains the dominant choice for body electronics, interior control, and actuator sub-networks in virtually every modern…

AUTOSAR E2E Profile 7: The Definitive Technical Guide to CRC-64 Large Data Ethernet Protection AUTOSAR E2E Profile 7 stands at the technological frontier of automotive functional safety communication – it is the only profile in the entire AUTOSAR E2E library that employs a full 64-bit cyclic redundancy check, making it the strongest data integrity guardian in the AUTOSAR safety communication…

AUTOSAR E2E Profile 6 Explained: CRC-32 Protection for CAN FD and Automotive Ethernet AUTOSAR E2E Profile 6 is the dedicated End-to-End safety communication protocol engineered specifically for SOME/IP (Scalable service-Oriented MiddlewarE over IP) – the primary serialization protocol used in AUTOSAR Ethernet-based service-oriented architectures. As modern vehicles increasingly adopt Automotive…

AUTOSAR E2E Profile 5 Explained: CRC-16 CCITT, 3-Byte Header, and CAN FD Ethernet Protection AUTOSAR E2E Profile 5 occupies a uniquely valuable position in the AUTOSAR End-to-End Communication Protection library – sitting precisely between the compact 8-bit CRC profiles designed for classic CAN and the heavyweight 32-bit and 64-bit CRC profiles designed for FlexRay and large Ethernet payloads.…

AUTOSAR E2E Profile 4 Explained: CRC32 Protection and Reliable Automotive Communication AUTOSAR E2E Profile 4 marks a pivotal step forward in the AUTOSAR End-to-End Communication Protection library. While Profile 1 and Profile 2 serve the bandwidth-constrained world of classic CAN with 8-bit CRCs and 4-bit counters, AUTOSAR E2E Profile 4 was engineered for a completely different league of…

AUTOSAR E2E Profile 1 Explained: CRC-8 SAE J1850, DataID Modes, and CAN Communication Protection AUTOSAR E2E Profile 1 is the original and most widely deployed safety protocol in the AUTOSAR End-to-End Communication Protection library. Specifically designed for the bandwidth-constrained environment of CAN (Controller Area Network) bus systems, AUTOSAR E2E Profile 1 delivers ISO 26262-compliant…
