Abstract
This paper presents a control and torque distribution method for Electric Vehicles (EVs) based on a slip ratio observer. The EV model used is a four-wheel model, developed and simulated in two different software environments: Matlab Simulink and CarSim. In addition, the paper incorporates a slip ratio observer to achieve optimal results. Firstly, the slip ratio of the four wheels is observed to monitor and adjust the steering force, thereby regulating the vehicle dynamics to ensure stability under various road conditions and achieve optimal driving performance. Next, the vehicle model is implemented in both software environments to compare and evaluate the differences in control effectiveness, accuracy, and simulation capabilities between the two tools. Finally, the simulation results from both software platforms are analyzed to provide valuable insights for selecting an appropriate simulation approach in the design and development of EVs, as well as to validate the effectiveness of the proposed slip ratio observation method.
