分布式驱动电动汽车通过多电机独立控制实现驱动方式变革，其扭矩分配策略直接影响车辆操纵稳定性。当前车辆高速转向与极限工况下存在侧滑失控风险，而传统集中式驱动难以精准调节轮间力矩平衡。扭矩分配的动态优化作为底盘主动安全的控制核心，成为提升复杂路况适应能力的关键技术。因此，文章就不同扭矩分配策略与底盘动态响应的耦合机制展开探讨，以期建立适应高动态工况的智能分配模型，为提升分布式驱动车辆的安全边界提供理论支撑。

Distributed-drive electric vehicles realize the change of drive mode through independent control of multiple motors，and its torque distribution strategy directly affects the stability of vehicle handling. Currently，there is a risk of side-slipping out of control under high-speed steering and extreme working conditions，and the traditional centralized drive is difficult to accurately regulate the balance of torque between the wheels. The dynamic optimization of torque distribution，as the control core of chassis active safety，has become the technical key to improve the adaptability to complex road conditions. Therefore，this paper discusses the coupling mechanism between different torque distribution strategies and chassis dynamic response，in order to establish an intelligent distribution model adapted to highly dynamic working conditions，and provide theoretical support for improving the safety boundary of distributed drive vehicles.
