Abstract: BACKGROUND: The traction electric drive control system is one of the key mechatronic systems of an electric vehicle, which determines the implementation of acceleration dynamics, regenerative braking, and motion stabilization. The complexity of the traction electric drive structure, the expansion of the number of modes and operating states, as well as the need to interact with third-party components, requires the structuring of the upper-level software architecture. A structured approach simplifies the development and scaling of the traction electric drive control system. Therefore, the development of a functional architecture and structure with an algorithm registry is relevant. AIM: Development of the functional structure and the algorithm registry of the mechatronic control system for the vehicle’s traction electric drive, which ensures the generation of control actions, data processing, diagnostics, and monitoring of the mechatronic system’s safety. METHODS: The traction electric drive control system software has been decomposed. The data flows and software module interactions have been analyzed to create the functional structure and the algorithm registry. RESULTS: The functional structure of the software of the mechatronic control system of the traction electric drive has been developed. The composition of functional groups, functions and algorithms providing processing of the received data, determination of driving modes, formation of traction and regenerative torque, limitation of slip of driven wheels and axles, as well as control of safe operation of the mechatronic system is presented. CONCLUSION: The proposed functional structure and algorithm registry allow to organize the software of the mechatronic traction electric drive control system, to ensure scalability and integration with third-party systems. The results obtained can find application in the development of the upper-level software of the mechatronic traction electric drive control system.
