摘　　要：车辆纵向控制指的就是车辆前进/后退方向的运动控制,包括了扭矩控制、离合控制、挡位控制和制动控制等几部分内容。自动泊车过程中的车辆纵向控制属于低速控制范畴,控制难度较大。尤其对于匹配双离合变速器的全自动泊车系统,纵向控制的各关联控制器存在控制策略相互冲突、系统集成匹配难度大等问题,需要系统性的研究相关纵向控制机理,从而优化系统集成匹配方案,满足全自动泊车系统对于纵向控制的要求。Vehicle longitudinal control refers to the motion control of the vehicle in the forward/reverse direction,including torque control,clutch control,gear control,and brake control.The longitudinal control of the vehicle in the automatic parking process belongs to the category of low-speed control,and the control is more difficult.Especially for fully automatic parking systems that match dual-clutch transmissions,the associated controllers of the longitudinal control have problems such as conflicting control strategies and difficulty in system integration and matching.It is necessary to systematically study the relevant longitudinal control mechanism to optimize the system integration and matching scheme to meet the requirements of the automatic parking system for longitudinal control.
