Development of an Optimized XCP Software Stack for Real-Time Validation of Vehicle Control Units Using Next-Generation Communication Protocols

In EVs, todays trend is to integrate power conversion and traction inverter subsystems by ensuring the increase in reliability and improvement in efficiency and cost effectiveness. The increased safety requirement poses risk of maintaining safety standards and increase in cost and time for manufacturing. The main integrated EV systems consists of Onboard charger, DC -DC converter and PDU. Each of the components and software is continuously evolving and it requires to be tested and validated in cost effective manner. The paper describes the design and development of XCP (Universal Measurement and Calibration Protocol) software stack for connecting calibration systems to electronic control units. The Software stack help in the read and write variable in the memory content of the microcontroller at run time. It’s a network Protocol Originated From ASAM. The software stack is easy to understand and platform independent, allowing it to be used on any microcontroller
