DoIP (Diagnostics over Internet Protocol) is a standardized diagnostic transport protocol for automotive electronics specified in ISO 13400.

What does the abbreviation DoIP stand for?

DoIP stands for "Diagnostics over Internet Protocol". DoIP is a diagnostic transport protocol for automotive electronics specified in ISO 13400.

What are the advantages of DoIP?

The DoIP (ISO 13400) standard enables much higher data rates than CAN, which represents a great potential for time and cost savings in complex diagnostic tasks and flash applications. Further benefits are: Performant handling of huge data volumes Time-saving at ECU Flash Programming Cost-efficient because no VCI is necessary Simple integration to IT Infrastructure Flexible use because of standardized communication Integrated with other standards for vehicle diagnosis Future-proof technology enables various use cases

How does data security work with DoIP?

Data security with DoIP is done via Transport Layer Security (TLS), the standard for encryption of communication. In this process, a secret is determined in a multi-step procedure via a slow but easy-to-use asymmetric encryption, which can then be used to exchange information very efficiently in the actual communication via a symmetric encryption. The procedure, which largely corresponds to the transition from http to https used in web browsers, enables very secure remote communication with control units and vehicles. The extension is already available in the current protocol stacks of Softing products.

Editing complex diagnostic tasks using DoIP

With Diagnostics over IP, diagnostic services introduced over UDS are used over TCP/IP and Ethernet. This enables much higher data rates than with CAN, representing great potential for savings both in terms of time and expenses in the case of complex diagnostic tasks and flash applications.

Ethernet-based communication allows new concepts in vehicle diagnostics, for example direct vehicle access from the tester even without a VCI and considerably simplified integration of the diagnostic interface into the IT infrastructure. In the case of service applications, when Ethernet and the legally prescribed CAN bus are to be operated, your best option is to use a powerful VCI.

Softing Experience

Based on its experience in diagnostics and communication as well as its participation in the ISO workgroup, Softing has played an active part in the definition of standards from the outset. The company's experience in linking VCIs by computer over Ethernet was of great significance.

DoIP is available for the diagnostic interface VIN|ING 2000. Protocol software with DoIP (ISO 13400) stack on the workstation for use with Ethernet cable and alternatively with support of the DoIP stack on the VIN|ING 2000.
