+
+论文题目：车智车辆租赁平台的设计与实现
+
+# 1. 任务和目标
+
+本课题的总体任务是设计并实现一个基于B/S架构的“车智车辆租赁平台”。该系统旨在利用现代Web技术(前端采用Vue.js框架,后端使用Java语言结合SpringBoot框架),构建一个连接车辆租赁公司与租户用户的数字化桥梁。通过提供车辆信息展示、在线选车、租期预定、订单管理等核心功能，解决传统租车流程中信息不透明、手续繁琐、地域限制等问题，为用户提供便捷、高效、透明的现代化租车服务体验。
+
+车智车辆租赁平台通过数字化手段连接车辆租赁服务商与消费者，打破了传统租车行业的信息壁垒和地域限制，为租车服务提供了更广阔的市场空间。这有助于提升车辆使用率，增加租赁公司收入，从而激发汽车租赁市场的活力，促进交通出行服务的多元化发展。
+
+汽车租赁作为共享经济的重要环节，车智车辆租赁平台很好地体现了这一经济模式的核心理念。依托平台的高效运营，不仅能够增强社会车辆资源的配置效率，还有效减少了资源闲置现象。同时，这一实践对汽车产业链的上下游产生了积极的带动作用，进
+
+一步推动了绿色出行理念的落地及可持续交通体系的构建，为实现更加环保与高效的出
+
+行方式提供了可能性。
+
+车智车辆租赁平台的设计与实现主要任务如下：
+
+(1) 根据系统的需求和毕设要求，完成字数不少于 2500 字的开题报告。
+
+(2) 根据项目的时间和实习的时间合理安排，拟定毕业设计进度计划表。
+
+(3) 确定题目的思路以及具体实现所需的技术。
+
+(4）本设计要求开发一个车辆租赁平台。
+
+顾客用户的功能模块划分为：登录注册模块，可租车辆模块，车辆详情模块，收藏夹模块，租车下单模块，归还车辆模块，实名认证模块，余额支付模块，个人中心模块，我的订单模块。
+
+管理员用户的功能模块划分为：管理员登录模块，特价车辆模块，车辆管理模块，订单管理模块，实名审核模块，用户管理模块，订单管理模块，数据统计模块，财务报表模块。
+
+(5) 开发车智车辆租赁平台，功能保证完善。
+
+(6) 撰写车智车辆租赁平台的论文。
+
+# 2.基本要求
+
+(1) 结合自己实习情况安排进度，填写进度计划表交给指导教师审核并严格执行；
+
+

+
+
+
+
+(3) 完成外文资料翻译，要求语言准确、流畅，译文至少 3500 字；
+
+
+
+
+
+(4) 论文要求 10000 字以上, 包括绪论、系统总体设计、系统实现和结论等内容;
+
+
+
+
+
+(5) 保证按照毕业指导进度稳定推进，服从指导教师安排的相关任务；
+
+
+
+
+
+(6) 制作答辩 PPT、准备答辩;
+
