Electric vehicle is considered to be the solution for energy crisis and environment pollution in individual transportation. However, electric vehicles are still not competitive with conventional vehicles limited by the driving range with the state-of-art power battery technology. Therefore, energy efficiency is of crucial importance for battery electric vehicles due to the limited stored energy...

Since car manufacturers pursue in the development of environmental -friendly vehicle, the demand for extensive research on stability, controllability, and reliability of electric vehicles (EVs) increases. Electric powered and by-wire control technology allow manufacturers to build independent four -wheel steering of an allwheel drive in-wheel EV. In past research, we investigated the advantages...

Tire forces are at the heart of the dynamic qualities of vehicles. With the advent of electric vehicles the precise and accurate control of the traction and braking forces at the individual wheel becomes a possibility and a reality outside test labs and virtual proving grounds. Benefits of individual wheel torque control, or torque-vectoring, in terms of vehicle dynamics behavior have been well...

Abstract With the help of several in-wheel motors, four-wheel independent-drive electric vehicle (4WIDEV) has tremendous potential to improve performance. Except for theme stability enhancement during past two decades, energy saving topic becomes more attractive recently. However, it is difficult achieve and economy performance simultaneously. Given commonly used control method rigid yaw rate t...

The project E-Vectoorc (Electric Vehicle Control of Individual Wheel Torque for Onand Off-Road Conditions) targets the development of an integrated controller for vehicle dynamics and energy efficiency for fully electric vehicles with one to four electric motors. The project is funded within the 7th European Union Framework Programme and unites two OEMs (Jaguar Land Rover, Skoda Auto), one supp...

differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...
