Abstract
As an important component of vehicle design and energy conservation, electric vehicle dynamics simulation is essential, especially under complicated testing conditions. The current commercial vehicle simulation software is mostly used for fuel vehicle dynamics simulation, which lacks accurate electric powertrain parts and open sources. To address this problem, this paper proposes an open-source and flexible vehicle dynamics simulation platform that includes 27 degrees of freedom (DOFs) based on Simulink, which can compatibly support both traditional vehicle dynamics simulations and electric vehicle dynamics simulations. In addition, the platform can support module customization, which is convenient for researchers. Although this platform still needs some iterations to reach industrial and commercial standards, it can already achieve parameter consistency under the stability demands in general scenarios. We believe this work should receive research attention and participation to provide lower thresholds and more references to the dynamic simulation of electric vehicles to reduce vehicle energy consumption.

Summary
As the number of electric vehicles increases, vehicle safety is becoming increasingly important. The above software cannot simulate electric parts, and their operation is cumbersome To address this problem and simulate the in‐wheel motors of the future, we establish an open‐source and flexible vehicle dynamics simulation platform that includes the high‐precision vehicle dynamics model and the powertrain model in Simulink [7,8]. We propose a high‐precision vehicle dynamics simulation open‐source platform for electric vehicles based on Simulink. We introduce an open‐source simulation platform for an electric vehicle dynamics system, which addresses the difficulty of modeling the bottom layer of traditional software; 2. The platform can provide accurate vehicle dynamics simulation and electric power‐ train simulation, and researchers can flexibly switch models through module selec‐ tion in our platform, which is not supported in the traditional software; 3.
