【摘要】 动感型汽车驾驶模拟器是一种能够正确模拟汽车驾驶动作,并能在主要性能上获得与实车驾驶相同感觉的仿真设备。采用汽车驾驶模拟器与实车驾驶相结合的培训方式,可以提高驾驶培训效率、缩短培训周期。因此,对汽车驾驶模拟器的研制具有十分重要的现实意义。本文针对动感型汽车驾驶模拟器的信息采集、处理与视景系统分别进行了研究。首先,详细介绍了采集对象一汽车驾驶模拟器操纵系统、采集元件的选择和采集电路的设计,完成了对三踏板、变速操纵机构、转向操纵机构的操纵量信息采集。其次,基于单片机Atmega128设计了电源模块、信息处理电路模块、控制电路模块和通信模块。按照RS422串行数据接口标准设定了通信协议,采用C语言编写了系统程序,完成了操纵系统与主控计算机之间的通信,实现了对汽车组合仪表、车灯等装置的控制。在视景系统研究中,以汽车动力学为基础,通过分析发动机功率、汽车加速度、汽车速度三者之间的关系,充分考虑了影响汽车运动状态的几个操纵输入量,如挡位、油门、离合、刹车及方向盘的动作状态等,建立了包括动力性方程和操纵稳定性方程的近似4自由度汽车动力学模型,同时,运用法国OKTAL公司开发的SCANeRⅡ软件建立了三维驾驶场景,并编写了部分特殊驾驶情景控制程序。更多还原

【Abstract】 Dynamic-type vehicle driving simulator is a simulated car, which can drive the right moves and get the same feeling on the main performance. Training which combines the vehicle driving simulator driving and a car driving can improve efficiency and shorten the training cycle. Therefore, the development of the training vehicle driving simulator is of great significance.In this dissertation, study on the information Acquisition, processing and visual system of dynamic-type vehicle driving simulator is proposed.Firstly, the acquiring target - vehicle driving simulator manipulators, the choice of acquisition components and the design of acquisition circuit are presented in detail in information acquisition system, which completes the acquisition of signals on three pedals, gear and steering wheel.Secondly, based on a single chip processor, Atmegal28, the power circuit, information processing circuit, control and communication circuit are developed. After setting the RS422 protocol and programming system procedure by C-language, the communication between the manipulation system and the master computer is completed, and the control of instrument, lights and other devices is realized.Finally, in visual system study, using of vehicle dynamics knowledge, analyzing the relationship among engine power, vehicle acceleration and speed, fully considering the effect of several manipulation inputs (including shift, throttle, clutch, brake and steering wheel) to motor action status, established an approximate 4-degrees freedom vehicle dynamic model which involves sport equations and manipulating stability equations. Applying the software SCANeRⅡwhich is developed by a French company OKTAL, a virtual driving scene is established and some special driving scenarios control procedures are programmed.更多还原
