央广网合肥9月23日消息(记者刘军 通讯员夏瑞)记者从合肥工业大学获悉,随着2017年中国大学生方程式汽车赛的日益临近,合肥工业大学日前正式推出由该校师生自主设计、制作的第八代汽油机方程式赛车、第五代纯电动方程式赛车和第一代无人驾驶方程式赛车。
据了解,合肥工业大学大学生方程式赛车创新团队旨在参加大学生方程式汽车大赛相关赛事,现有越影、云电、睿智三支车队。合肥工业大学越影车队作为安徽省目前唯一参赛的油车队,在“中国大学生方程式汽车大赛”中屡获佳绩。合肥工业大学云电车队现拥有队员60余人,其每年都会自主设计制作出一辆纯电动车方程式赛车参加国内、外赛事。合肥工业大学睿智智能车队是针对中国大学生无人驾驶方程式大赛新成立的车队,其口号是“更安全,更精准,更创新”。
睿智车队技术总监方涛介绍,合肥工业大学新发布的第一代无人驾驶赛车是基于云电四代赛车改造而来,在环境感知层、智能决策层、执行控制层均有技术革新。“环境感知层相当于赛车的眼睛,是由激光雷达、摄像头和高精度GPS组成;智能决策层相当于赛车的大脑,处理眼睛接收的信息进而分析处理;执行控制层相当于四肢,用于横纵向控制。”方涛介绍说,“多数无人驾驶赛车都是以激光雷达感知环境为主,但我们这款赛车采用了以摄像头为主的摄像头、激光雷达、差分GPS数据三者融合的技术方案,大大提高了判断障碍物大小和位置的精准性。”
此外,越影第八代赛车已经历了近一年的精心打磨,越影车队技术总监张志先介绍说,今年新设计制作的越影八代在底盘部分采用了新的材料和结构设计,在驱动部分使用了曲面翼设计,在动力总成部分同样进行了创新。“我们的百米加速可以达到4.2秒,而且底盘有全新的数据采集系统,搭载自制仪表,能更客观地体现底盘的相关数据。”张志先说。
而云电第五代赛车的技术创新主要体现自组三元聚合物锂电池、数据采集无线发送、全套空气动力学套件、横向稳定器及第三阻尼四大方面。云电车队技术总监齐兴华介绍说,“今年,我们在轻量化、赛车稳定性与动力性上做出了突破,采用了新的结构来减重,同时加装了侧翼,应用双电机独立驱动。”整个云电五代花费了3个月设计、4个月加工、3个调试,除去电动机,全车90%的零件都由团队成员手工完成。
