The Author in this book investigates the different aspects of all-electric vehicles and compares them to the conventional internal combustion engine cars; this book looks into advanced traction control systems of electric vehicles with four independent in-wheel electric motors. The author, primarily, explains the steps toward the design of an electronic differential, which will significantly advance the operation and the efficiency of the drive-train. He will then presents the advantages of an electronic differential in order to improve a vehicle's performance by extending the control range of the motors.
