Vehicle with Electronic Differential Speed Control for Two In-Wheel Motors

Electrical Engineering

We model an electronic differential in this work that will provide the best vehicle stability on a curved route. The usage of an electronic differential is a step forward in vehicle design in the direction of more electric automobiles. Electronic differentials have the advantage of replacing inefficient mechanical transmissions and differentials with more efficient, light, and tiny electric motors directly linked to the wheels through a single gear or an in-wheel motor. Electronic differentials for two and four wheeled vehicles have been proposed thus far. Two permanent magnet synchronous (PMS) machines are used in the proposed traction system to drive two back-driving wheels.For each wheel-motor, the suggested control mechanism is based on direct torque control. A vehicle was driven on a straight road, a straight road with a slope, and a vehicle was driven on a road that curved left and right, among other simulations. On a curving road, the simulation results show good vehicle stability.
