This paper is aimed at providing an insight into the torque vectoring concept which will be incorporated into the dual-motor drive system of the Electric Arc vehicle. The torque vectoring algorithm is based on Ackerman steering geometry and will become the basis of electronic differential which will vary the speed of the two rear driving wheels while cornering. The electronic differential acquires steering and vehicle speed data before computing the corresponding cornering response for each rear driving wheel using yaw rate prediction from the Ackerman steering geometry. Several series of Excel simulations were done to illustrate neutral steer, understeer and oversteer cornering cases for different cornering radius with varying vehicle speed and the cornering responses for each case was analyzed. This paper will also highlight how on-track testing of Electric Arc can verify the Excel simulation results and consequently determine tire cornering properties.
