The torque distribution strategy plays a crucial role in improving the safety and energy efficiency of distributed drive electric vehicles. In order to reduce the energy consumption of electric vehicles with dualmotor drive on the front and rear axles, a multiobjective torque distribution method based on a hierarchical control architecture is proposed in this paper, that comprehensively considers vehicle safety, handling stability, and energy efficiency. The upper layer is the active safety layer, which uses nonlinear model predictive control (NMPC) to achieve vehicle safety and stability control. The lower layer is the torque distribution layer, which considers the torque control of the front and rear axle motors under noload loss of the motor. The simulation results show that compared with the average distribution method, the proposed multiobjective torque distribution method can improve the vehicle's stability while ensuring safe driving, with the total energy consumption reduced by 6.6% and 3.5% under the NEDC and WLTC driving cycles, respectively.
