Validation of Dynamic Model for Communication Networks in Electric Vehicles

Since the first implementation of electronic modules in conventional vehicles, communication between them was essential, CAN (Controller Area Network) was created to the communication between these modules. Advances in CAN have made it the most used communication protocol in electric vehicles. The communication networks present in electric vehicles demand high efficiency and control for the exchange of information between electronic modules. The use of various active, passive and electric traction safety systems generates a constant exchange of information and data that are important for the proper functioning of the electric vehicle. This paper presents the validation of a dynamic model for communication networks in electric vehicles. The model allows to analyze the frames of CAN and obtain the identifiers of the traction and speed modules to obtain a tool for validation during a fault situation. The main objective is the monitoring of the communication network to analyze possible failures that can be generated during operation. For the development of the model, the communication network configuration of a Kia Soul Electric vehicle is analyzed using Simulink-Network Vehicle Toolbox, LabVIEW-Ni-Xnet and the data acquisition card NI-9862.
