基于Solid Works Motion的车辆自动跟随行驶仿真

Vehicle auto tracking simulation based on solidworks motion

随着汽车产业与互联网的发展,依靠计算机系统智能驾驶替代人工驾驶已成为汽车发展的新趋势;ACC自适应巡航技术虽然依旧需要人工驾驶,但可使用电控程序解决车辆在车流中保持合理的跟车间距。基于无人驾驶和自适应巡航的理论基础,提出一种介于两者之间的行驶模式,即在两辆车同向行驶时,前车人工驾驶,后车自动跟随行驶,并采用Solidworks进行车辆三维建模;并用Motion运动仿真插件模拟车辆前车在加速、减速、匀速直线及弯道转向运动状态,观察后车跟随情况,获得了相应的车辆跟随动力学仿真结果。

With an increasing growth of the automobile industry and the Internet,it has become a new trend to replace manual driving with intelligent driving relying on computer system.Although the ACC adaptive cruise technology still requires manual driving,the electronic control program can be used to maintain a reasonable following distance in the traffic flow.Based on unmanned driving and adaptive cruise control theory,this paper proposes a driving mode between these two,i.e.,when two cars are driving in the same direction,the front car drives manually and the rear car will follow automatically.Moreover,Solidworks is adopted for vehicle 3 D modeling.The motion simulation plug-in is used to simulate the state of the acceleration,deceleration,uniform straight line and corner steering motion for the front vehicle,and then observe the following vehicle following situation,obtaining the corresponding vehicle following dynamics simulation results.
