ComStack, short for Communication Stack, is a key component in automotive software architecture, particularly within the AUTOSAR framework. It handles the communication between various ECUs (Electronic Control Units) in a vehicle using protocols like CAN, LIN, FlexRay, and Ethernet. ComStack is responsible for abstracting communication layers, ensuring seamless data exchange across different modules and subsystems, whether for vehicle diagnostics, control signals, or infotainment systems.
In the automotive domain, ComStack provides a standardized communication interface that simplifies development and ensures interoperability between ECUs. It includes key modules like CAN Network Management (CanNm), CAN Transport Protocol (CanTp), and PDU Router (PduR), which manage message transmission, routing, and diagnostics. ComStack’s reliability and real-time communication capabilities are essential for ensuring the functional safety and efficiency of modern vehicles.
we provide a robust communication stack designed to facilitate seamless ECU interaction and reliable data exchange in automotive systems. Our stack includes essential vehicle communication protocols such as CAN, LIN, and Ethernet, ensuring effective communication across various subsystems. To enhance data transmission capabilities, we incorporate transport protocols like CAN TP (CAN Transport Protocol) and J1939 TP (SAE J1939 Transport Protocol), which efficiently manage larger data packets, ensuring accurate message routing and delivery.
Additionally, we integrate the COM (Communication) module and PDUR (PDU Router) to effectively manage and route Protocol Data Units (PDUs) across the communication layers. This structured approach allows for smooth, real-time communication between ECUs, improving overall system diagnostics and performance. By leveraging expertise in communication stack, Amarakosha ensures compliance with automotive safety standards such as ISO 26262, providing a scalable and reliable solution for modern vehicle systems.
