基于面向对象的汽车防撞控制系统的设计

Design of Vehicle Crash-Avoiding Controlling System Based on Oriented-Object

汽车主动防撞控制系统的研究主要集中在主动防撞预警和驾驶控制模型方面,对防撞控制系统的整体分析建模涉及较少。因此在分析国内外汽车防撞系统研究的基础上,建立了汽车防撞控制系统整体模型,模型包括雷达传感器、车辆模糊控制器和车辆接口并探讨了车辆跟驰最小安全距离控制算法。在遵循驾驶员优先的原则下,根据建立的防撞控制模型,利用面向对象方法对汽车防撞控制系统进行了深入的分析和设计,借助UML建模语言,从需求入手,逐步深入,对模糊控制器的模糊事实类、模糊规则类、模糊结果类进行详细的分析设计,建立了系统的静态视图和动态视图。实践证明该系统模型为汽车主动防撞控制系统研究提供了合理、适用的仿真及结果。

The research of vehicle active crash-avoiding controlling system is mainly concentrated in vehicle collision warning system and driving controlling model,in the analysis of the entire model involving a relatively small.So,vehicle crash-avoiding fuzzy controlling model is developed based on research of vehicle collision warning system at home and abroad,which includes three parts such as radar sensor,collision prevention controller processor and vehicle interface.Furthermore,algorithm of minimum safe distance was proposed under the condition of car-following.According to the principle of driver precedence,the oriented-object method was adopted to analyze and design software of vehicle crash-avoiding fuzzy controlling system.From requirements capture,fuzzy fact class,fuzzy rules class and fuzzy results class were analyzed,with Unified Modeling Language,in considerable detail.Static view and dynamic view were established to describe the vehicle crash-avoiding fuzzy controlling system.Practice has proved that the system model provides a reasonable,applicable simulation and results for vehicle active crash-avoiding controlling system.
