摘　　要：为提高AMT(Automated Mechanical Transmission)车辆纵向期望速度控制的快速性及适应性,提出一种基于油门、挡位的2参数纵向期望速度控制方法。首先根据车辆动力学模型进行广义地面阻力系数求解,建立了换挡查表模型,然后对用于油门控制的模糊PID控制器进行设计,并以某型配备AMT变速箱的履带车辆为研究对象建立仿真模型,通过仿真实验对所提出的纵向期望速度控制方法进行验证,以换挡决策时间、纵向期望速度控制响应时间和车辆行驶距离为评价指标对该方法进行评价。仿真结果表明:所提出方法对于纵向期望速度指令及路面情况变化可迅速做出换挡决策,可以满足速度控制快速性及适应性要求。In order to improve the rapidity and adaptability of AMT(Automated Mechanical Transmission)vehicle longitudinal expected speed control,a dual-parameter longitudinal expected speed control method based on throttle and gear is proposed.Firstly,the generalized ground resistance coefficient is solved according to the vehicle dynamics model,and the shift lookup table model is established.Taking a tracked vehicle equipped with AMT gearbox as the research object,the simulation model is established.The proposed longitudinal expected velocity control method is verified by simulation experiments.This method is evaluated with shift decision time,longitudinal expected speed control response time and vehicle driving distance as evaluation criteria.The simulation results show that the proposed method can quickly make shift decisions for the changes of longitudinal expected speed command and road conditions,and can meet the requirements of rapidity and adaptability of speed control.
