# e$^2$-Lenk - A novel concept for power steering using wheel individual electric drivetrain

Mayer, Marcel Ph.; Frey, M. ; Römer, J.; Kautzmann, P.

##### Abstract (englisch):
The internal combustion engine of conventional vehicles not only accelerates the car but also supplies auxiliary systems with energy; such as the assisted steering system, which reduces the driver’s effort at the steering wheel. In electric vehicles, this energy is provided by battery and reduces the range as a result. However, is a dedicated power steering system needed in vehicles with wheel-individual electric drives? The joint research project "e²-Lenk" subsidized by the Federal Ministry for Education and Research (BMBF) focuses on a novel assisted steering concept for electric vehicles. If wheel torques on the steered axle are distributed in an intelligent way, this will evoke a resulting steering torque and have a positive effect to the driver's steering effort.

In this contribution, an investigation is presented that shows the influence of different wheel torques on the subject of reducing the steering wheel torque. To enable a profound statement, the possibility to depict realistic chassis geometries is necessary. In contrast to elementary two-track models, the use of IPG CarMaker as a vehicle dynamics simulation tool is proposed. ... mehr
