To address the issues of significant slip energy dissipation induced by severe tire slip, degradation of vehicle control stability, and insufficient accuracy of vehicle speed tracking under low-adhesion road conditions, a torque coordination control strategy for dual-motor electric vehicles (DM-EVs) considering load transfer and slip energy dissipation is proposed. First, a vehicle dynamics model integrating suspension system dynamics and tire slip characteristics is developed, fully accounting for the influence of front-rear axle load transfer on the tire slip ratio. Next, founded on the energy dissipation mechanism of tire slip, a quantitative model for energy dissipation during tire slip is developed. Finally, a longitudinal coordinated control system for vehicles according to nonlinear model predictive control (NMPC) is introduced. By comprehensively considering the tire slip ratio and vehicle load distribution, multi-objective coordinated optimization of wheel torque is achieved. Simulation results under constant acceleration conditions on low-adhesion roads indicate that significant slip phenomena occurred in the wheels of both the without slip ratio controller and the PID controller, failing to achieve stable vehicle control. Simulation results in virtual traffic scenarios reveal that, compared to the other two controllers, the proposed controller exhibits significant reductions in key performance metrics: the RMS value of total tire slip ratio is reduced by 84.95% and 87.34%, total tire slip energy dissipation is reduced by 94.95% and 96.53%, and total tire wear volume is reduced by 93.78% and 95.71%, respectively. These results demonstrate the performance of the introduced control strategy.
