摘　　要：离合器控制是影响自动变速器换挡平顺性的重要因素,传统的控制方法难以对自动离合器这种大滞后、非线性系统进行精确的控制。综合考虑将换挡平顺性和发动机稳定运转等因素作为系统约束,以换挡时间最短、滑磨功和冲击度最小作为设计目标,设计了基于模型预测控制(MPC)算法的自动离合器结合控制器。通过仿真和实车试验验证,与模糊逻辑控制算法相比,模型预测控制算法能有效地降低换挡过程中的冲击度和滑磨功,提升了换挡品质。Clutch control is an important factor affecting the smoothness of automatic transmission shifting,and traditional control methods are difficult to accurately control large hysteresis and nonlinear systems such as automatic clutches.Taking into account factors such as shifting smoothness and stable engine operation as system constraints,and with the design goals of minimizing shifting time,sliding wear and impact,an automatic clutch engagement controller based on Model Predictive Control(MPC)algorithm is designed.Through simulation and actual vehicle testing,it is verified that the model predictive control algorithm can effectively reduce the impact and sliding wear during the shifting process,and improve the shifting quality,compared with fuzzy logic control algorithm.
