Design and Implementation of Controller Area Network-Transport Protocol Software Based on C#

Performing Measurement, Calibration, and Diagnosis (MCD) work through automotive electronic control systems is a primary aspect of vehicle upgrade and maintenance. Nowadays, as the core component of automotive electronic control systems, every Electronic Control Unit (ECU) requires MCD operations to ensure the normal functioning of vehicles. The Controller Area Network-Transport Protocol (CAN_TP) is a network transport layer protocol based on CAN bus communication within MCD systems. This paper presents the development of CAN_TP software according to the ISO 15765–2 standard. The CAN_TP software facilitates data interaction between a Personal Computer and the ECU, providing convenience for vehicle MCD operations.
