摘　　要：针对现有分布式驱动电动汽车驱动力控制系统在进入驱动防滑工况时纵向驱动转矩和加速度降低以及产生非期望的横摆力矩和横摆角速度等问题,提出了两种多轮驱动转矩协调控制策略。其中,基于动力性的驱动转矩协调控制策略的目标是改善纵向驱动转矩和加速度,而基于稳定性的驱动转矩协调控制策略的目标则是增加车辆的横向稳定性。实车实验结果表明,所提出协调控制方法有效实现了设计目标,改善了车辆性能。For tackling the problem of the reduction in longitudinal driving torque and acceleration as well as the occurrence of undesired yaw moment and yaw angular velocity when the driving force control system of distributed drive electric vehicle enters the working mode of acceleration slip regulation,two multi-wheel driving torque coordination control strategies are proposed.Among them the strategy for power performance is aiming at raising longitudinal driving torque and acceleration,while the strategy for stability is targeted at enhancing the lateral stability of vehicle.The results of real vehicle test show that the proposed coordination control scheme effectively achieves the design objectives and improves the performance of vehicle.
