Abstract
This paper is a study on the torque vectoring control logic of a twin-clutch axle system that replaces the existing differential system. This system controls the pressure of the torque vectoring clutch to control the driving torque of each wheel and generate yaw motion to improve cornering performance or vehicle stability as desired by the driver. To make this possible, the controller needs to perform appropriate calculations. The proposed control logic is composed of a combination of open-loop control and closed-loop control to improve control accuracy, stability, and responsiveness. Additionally, to ensure stability under various driving conditions, a reference yaw rate considering tire slip angles was calculated. To evaluate the performance of the proposed logic, simulations were performed and the results were analyzed.
