Torque distribution control systems and methods for through-the-road electrified vehicles having distinct first and second torque generating systems for distinct first and second axles, respectively, utilize existing vehicle sensors to (i) obtain measured wheel rotational speeds and a measured steering wheel angle, (ii) estimate virtual yaw rates of the first and second axles using these measured values and other known vehicle parameters, (ii) predict whether oversteer or understeer of the vehicle is likely to occur based on the estimated first and second axle virtual yaw rates, and (iv) when oversteer or understeer of the vehicle is predicted to occur, adjust a torque distribution between the first and second torque generating systems to prevent the oversteer or understeer from occurring and to keep the vehicle on a constant turn path.
