Java程序设计课程设计项目名称

?

项目名称:自动挡汽车操作模拟系统的设计与实现

英文名称:Design and Implementation of Operation Simulation System aboutAutomatic Vehicle

1、功能描述:

1)汽车的操作正常为启动(或熄火)、挂档、制动、油门控制等操作;

2)挂档实现自动挡的4档操作,既驻车档、倒车档、空档、行车档;

3)使用图形界面进行操作,汽车的状态在图形界面上显示出来;

4)操作流程不合理,要有相应的控制;

5)附加功能:

(1)汽车的油也要进行控制,发动机需要消耗汽油,提供汽油报警功能;

(2)汽车的行程数进行控制,用户界面显示当前行程数;

6)正常操作流程为:启动->刹车->挂档->放刹车->汽车运动->加油门->刹车->驻车档->熄火。行驶中严禁换挡,行驶档位不能启动。

参考文档:

【1】系统类的API文档,见CarApp.jar文件内的doc下的index.html文件

【2】系统运行效果,使用控制台,输入命令为:java –jar CarApp.jar

【3】汽车的运行可以选择gif文件,从网上搜索关键词“车运动? gif”或“动漫小车”等关键字搜索你喜欢的gif小车运动图片,然后使用“工具GIF帧提取器 V1.1 绿色版.rar”提出图片中的每帧图片。

【4】系统的运行效果参考图见图1.
