Torque Distribution for Slip Ratio Minimization in Electric Vehicles and Its Energy Saving Effects

Because the one-charge mileage of an electric vehicle is susceptible to constraints on battery capacity, in this study, we examined the tire force distribution, focusing on the energy dissipation due to slippage between the road surface and tires to reduce energy loss. We found that, in comparison to a two-wheel drive system, the optimization of the longitudinal force distribution in a four-wheel drive system considerably affected energy savings. Under more generic driving conditions, such as acceleration/deceleration during turning, we determined the optimal tire force distribution and examined the effects of direct yaw-moment control.
