Control of Vehicle Dynamics for an All-Wheel Drive Electric Vehicle

This paper deals with modelling of vehicle dynamics and development of control system for a Formula Student all-wheel drive electric vehicle developed by the STUBA Green Team. The aim is to exploit traction of all tyres to achieve a better racing performance and thus innovate the current control system. Proposed models describe the effect of traction forces on tyre loads and the directional stability of the vehicle. The control system was validated in the simulation environment IPG CarMaker. Simulation with equal torque distribution (without torque vectoring) was used as a reference. The simulation results have shown a considerable improvement of vehicle stability in corners.
