Application of Independent-Left-and-Right-Wheel-Driving Force Controller to Torque Vectoring Differential with Two-Input-Two-Output Motor Drive System for Electrified Vehicles

A torque-difference-amplification torque vectoring differential (TDA-TVD), which is composed of a two-input-two-output system, has a great potential for cornering maneuverability; however, the overall controllability of slip ratio or driving force control is difficult owing to its complex mechanical...

Description
Summary:A torque-difference-amplification torque vectoring differential (TDA-TVD), which is composed of a two-input-two-output system, has a great potential for cornering maneuverability; however, the overall controllability of slip ratio or driving force control is difficult owing to its complex mechanical structure. In order to enhance the controllability of TDA-TVD, this study proposes a design method to apply a driving force controller (DFC) with a decent slip ratio and driving force controllability, which was originally intended for independent wheel drive systems. An experimental verification on a slippery road using a real vehicle with the TDA-TVD indicated that the DFC can be applied to the TDA-TVD and that it improves the overall performance of the traction control.
