Design of an Electric Differential System for Three-Wheeled Electric Welfare Vehicles With Driver-in-the-Loop Verification
In this paper researchers propose an electric differential system (EDS) for applications in three-wheeled (3W) electric welfare vehicles (EWV). 3W vehicles often experience weak right/left rear tractive forces and consequentially increasing the steering angle and torque required for cornering due to the absence of a traditional mechanical differential. Using driver-in-the-loop testing, researchers analyze the proposed system in order to determine its efficacy in replacing the traditional differential. The system works by translating throttle input into tractive torque, which then obtains a reference vehicle speed. This speed can be used as a cross-reference against a table of desired yaw rate gains. Ackerman geometry can then provide the proper reference rotational speeds for both outer and inner wheel motors. The authors also propose to apply this method to four-wheeled (4W) vehicles.
