Exploring DoIP from an Automotive Context

Diagnostics over IP (DoIP) is a protocol designed to manage diagnostic communication over Ethernet, serving as a modern alternative to traditional CAN (Controller Area Network)-based diagnostics. It enables faster and more efficient transmission of diagnostic commands and control messages, impacting vehicle maintenance and management.

Key Features of DoIP

OSI Model Integration

DoIP operates by having any diagnostic command over Ethernet traverse the seven layers of the OSI (Open Systems Interconnection) model to the application layer. Once at the application layer, the command transfers to a CAN application to perform tasks such as flashing the device. This integration ensures reliable diagnostic communication.

Excelfore’s DoIP Solution

Excelfore offers a comprehensive DoIP middleware solution that supports all three configurations—client, server, and gateway. Our solution adheres to the ISO 14229:2021 standard, ensuring compatibility and reliability across diverse automotive systems. This compliance ensures that our DoIP solution meets the demands of modern automotive diagnostics.

Customers are provided with sample applications and complete API documentation and a library for their integration. DoIP support is available on Linux, QNX, Integrity, FreeRTOS, etc.

DoIP supports three configurations: client, server, and gateway. This flexibility allows DoIP to be adapted to various use cases within automotive systems, offering robust and adaptable diagnostic capabilities.

Deployment and Usage

DoIP is predominantly used for flashing devices, a critical function in automotive diagnostics and maintenance. By leveraging Ethernet, DoIP improves the speed and efficiency of these operations. This is particularly beneficial for tasks requiring the rapid and reliable transfer of large data volumes.

Excelfore’s DoIP and suite of diagnostic protocol solutions ensure that automotive manufacturers can leverage this protocol to enhance their diagnostic capabilities.
