Ans. UDS protocol is a standard defined in ISO 14229 document. The UDS protocol specifications are independent of physical layer and commonly used over CAN, LIN, Flexray and Ethernet physical layers.
The UDS protocol stack is an ISO 14229 compliant software solution. This UDS software stack is best suited for automotive ECU and tooling applications in Passenger Cars.
Ans. Our UDS software stack can be customised to include UDS services defined as per the ISO 14229 standard.
In addition to these services, our UDS protocol solution includes:
- Diagnostic over CAN (as per ISO15765)
- Diagnostic over LIN (as per LINTP)
- Diagnostics over IP (DoIP).
The following SIDs/services are included in our UDS stack solution as a standard software package Additional UDS diagnostics services can be included as per your project requirements.
Ans. We can help you generate the ODX file from the specifications provided by either by your team or your customer’s team (OEM).
Our Automotive software team has expertise in tools like CANdela and equivalent .
Also, we can support for generation of UDS Protocol configuration file based on the ODX file. We have expertise in tools like Vector GenY & equivalent, that are necessary for generation of UDS Protocol configuration file.
Ans. As part of the SLA, our software team will work closely with your team to analyse the end-user application.
Based on your business requirements, we can provide end-to-end support for the customization and integration of the UDS stack with your hardware platform and software application.
To summarize, we will partner with your team to deliver following services along with the stack:
- Integration of the UDS stack to your hardware platform
- Integration of UDS solution with target application
- Development of bootloader software based on UDS standard
- Development of driver modules like CAN, LIN, Ethernet and more
