Advanced Redundancy Technology for a Drive System Using In-Wheel Motors

In electric vehicles that use in-wheel motors, the right and left traction forces become unbalanced if a motor malfunctions by motor lock or loss of traction, generating yaw moment. Control methods were designed to reduce this effect by stopping the motor output on the opposite side of the same axle. By using a prototype “Eliica” car, the maximum yaw rate and lateral acceleration were compared ...

Wheel Speed Control Algorithm for Rear Wheel Motor Driven Vehicle

The conventional vehicles in the past had consisted of mechanical differential which converts the engine torque in to two directions. Due to the introduction of electric vehicle the vehicle propulsion system has changed from combustion engine to electric motor. Since the concept of differential is a must have component to drive a vehicle, it is still used in electric vehicles as well. Common me...

Reducing the Motor Power Losses of a Four-Wheel Drive Fully Electric Vehicle via Wheel Torque Allocation

Individually-controlled electric motors provide opportunities for enhancing the handling characteristics and energy efficiency of fully electric vehicles. Online power loss minimisation schemes based on electric motor efficiency data may, however, be impractical for real-time implementation due to the heavy computational demand. In this paper, the optimal wheel torque distribution for minimal p...
