Abstract
This work aims to perform a hazard analysis and a risk assessment considering vehicle handling and control when an electric drivetrain delivers power to the ground with the support of a torque vectoring control system. In addition, the objective is to discover pathways to dynamics control that allows the synthesis and implementation of devices that yield improvements to vehicle handling. The scope of the evaluation is to assess the impact of the actuator's limitation on a Formula SAE Electric Vehicle independently driven by rear in-Wheel motors. The context considers the component's limitations in coping with a torque vectoring strategy composed of feedforward and feedback signals. This strategy is derived using the simplest model for evaluating lateral vehicle dynamics, a bicycle model. However, the impact of the actuator's limitation is numerically assessed using a vehicle model comprising a TMEasy Tire model, suspension parameters, and the lateral transfer load. Preliminary conclusions are drawn based on these results. This strategy demonstrates the importance of evaluating the safety of the intended functionality of the system's components.
