摘　　要：为在驱动转向复合工况下有效抑制分布式驱动电动汽车的纵滑、侧滑,提出了一种面向驱动转向复合工况的分布式驱动稳定控制架构,设计基于横摆角速度和侧偏角跟踪控制的横摆控制策略和基于滑转率跟踪控制的驱动防滑控制策略,同时根据转向稳定状态对目标滑转率进行调节,根据车辆行驶状态对横摆控制与驱动防滑控制输出扭矩进行协调优化,以实现车辆纵向、侧向稳定控制。仿真测试和实车试验结果表明:所提出的控制策略能够在驱动转向复合工况下使车辆保持良好的不足转向特性和轨迹跟随能力,车辆纵滑和侧滑得到有效抑制。To effectively restrain longitudinal and side slip of distributed drive electric vehicle under acceleration steering condition,this paper proposes a stability control architecture of distributed drive for acceleration steering condition.The yaw control strategy based on yaw rate and side slip angle tracking control and drive anti-slip control strategy based on slip rate tracking control are designed.The target slip rate is adjusted according to vehicle steering stable state,and the output torque of yaw control and acceleration slip regulation control is coordinated according to the driving state,thus vehicle longitudinal and lateral stability control are realized.Simulation test and vehicle test results show that the proposed control strategy enables the vehicle to maintain good understeering characteristics and track following ability under acceleration steering condition,effectively suppress vehicle longitudinal and lateral slip.
