Product Description

The use of reliable diagnostic protocol software stack is essential when setting up in-vehicle network. The use of ready to use standardised software components guarantees ease of portability and smooth integration of different ECUs in the Vehicle networks for the automotive OEMs and its suppliers. Furthermore, the ready to use software components leads to a reduced development cost and project timeline.

ElectRay's eSAR.UDS stack is based on ISO 14229 standard and compliance with AUTOSAR R4.4.0 . The eSAR.UDS stack is designed to be used in Automotive, Commercial vehicles and Motor bikes ECUs. The Diagnostic trouble codes and fault memory is part of the eSAR.UDS stack. The standalone configuration tool helps to customise the features to meet the end application requirements.

The eSAR.UDS stack can be used in AUTOSAR or conventional ECU software environment. It can also be configured to accommodate the memory needs of the small footprint ECUs.

Note: NV data storage handling implemented as per the AUTOSAR standard using standardised API's and can be easily ported with any third party Flashing libraries.
