摘　　要：自适应巡航控制(ACC)是一种可以有效减轻驾驶员的驾驶疲劳,提高车辆安全性的主动安全技术。对于长途机动的军用车辆具有广阔的应用前景。文章以陕汽某型号三代重型高机动军用车辆为目标车型,设计了基于模型预测控制(MPC)的车辆自适应巡航控制系统。并依据目标车型的性能参数及ACC系统的控制策略,以车辆动力学仿真软件Truck Sim和Simulink为平台,建立了目标车型的整车纵向动力学和控制策略联合仿真模型。仿真研究所设计的ACC系统在不同的巡航工况下对前方目标车辆的跟随能力及自车的驾驶舒适性。仿真结果表明,文章设计的ACC系统能使自车在保持一定安全车距的前提下,较好的跟随前方目标车辆,同时提供良好的驾驶舒适性。Adaptive cruise control（ACC）system belongs to active security technology, It aims at reducing the workload of driver and improving vehicle safety. The technology have widely developing prospect for military vehicle that used on long-distance transport. This article choose a 3rd heavy expended mobility tactical vehicle as the target vehicle, designed the adaptive cruise control system based on model predictive control（MPC）. On the platform of TruckSim and MATLAB/ Simulink, longitudinal dynamic model of vehicle and control model of ACC was established. Finally a co-simulation is conducted on typical ACC driving condition. The simulation results show that the ACC system designed can well follow the speed change of leading vehicle while keeping a certain distance, and has a better controllabitity for the driver.
