【摘要】 混合动力汽车是传统内燃机汽车到电动汽车的过渡产品,它不仅具有传统内燃机汽车优良的动力性和较长的续驶里程,还具有纯电动汽车高效率、低排放的性能,因此混合动力汽车得到了各个汽车生产厂家和科研单位的青睐。然而随着混合动力汽车研究的深入,一些关键技术仍严重制约着它的发展,比如参数匹配、控制策略的优化、动态过程的切换和能量存储装置及其管理系统的开发等等,这些技术研究能否取得突破已成为影响混合动力汽车推向市场的关键因素。试验是解决上述问题的最佳途径,试验不仅可以解决仿真初期所不能模拟的复杂的数学模型和实际环境,而且试验还能验证设计思想和理论方法,能进一步分析出存在的影响因素和问题。与整车试验相比,台架试验有试验危险系数小、零部件容易布置等特点,根据具体的试验对象和试验内容可以取代整车试验。由于混合动力汽车结构比传统汽车更加复杂而且难以控制,因此混合动力汽车的开发应建立在试验台架的基础上进行分析研究。首先,本文研究混合动力汽车试验台的相关技术,在选取并联混合动力汽车结构形式的基础上,建立基于再生制动功能的试验台总体设计方案,并对试验台各部件进行选型及参数设计。其次,基于模块化设计思想,借助于Matlab/Simulink和ADVISOR软件建立混合动力试验台再生制动系统的各部件仿真模型。依据传统汽车的制动性能评价指标,并结合混合动力汽车的特点,提出混合动力汽车再生制动系统制动性能的评价指标,然后选择典型的制动工况和和城市驱动循环工况对再生制动试验台进行离线仿真,从而验证试验台架的可行性。最后,应用LabVIEW软件搭建再生制动试验台的用户操作界面,实现试验台可视化人机互动操作,并为日后的试验台硬件在环仿真及整车试验的数据处理提供一个良好的可视化试验操作界面。本文所研究的内容对今后混合动力汽车试验台的搭建、整车试验以及混合动力汽车的开发奠定了基础。更多还原

【Abstract】 Hybrid electric vehicle as the transition product of traditional vehicle to electric vehicle, which combines the excellent power and distance performance of conventional vehicle with low mission and high efficiency of Electric vehicle, so hybrid electric vehicle is favored by many vehicle manufactures and research institutions in recent years. However,with the profound research of HEV,some key technologies obstruct its progress,such as parameters matching,optimization of control strategy,dynamic state switching and energy storage device and its management system. It has become the key factor about HEV’s general adoption of market that research of these technologies can make breakthrough or not.Test is the most effective method of resolving above problem,which not only can resolve the complex but can not simulated mathematic model and actual environment during simulation,but also can validate the design ideology and theoretical method,and analyze further the existed factors and problems. Comparing with vehicle test and bed test,dangerous coefficient of the benefit of bed test is small and components is easy to lay ou,so bed test may replace the vehicle test on the base of objiects and contents tested.Comparing with HEV and traditional vehicle,HEV is hardly controlled,so the development of HEV is based on the analysis and study of HEV test bed.At first,the correlation technique of test bed is studied,choosing the parallel HEV structural style,and the test platform overall project design is established based on the electric regenerative braking function.The type models of test bed various parts are chosen and the parameters are designed.Then based on the model design concept, the electric regenerative braking system’s various part models of test bed are established using Matlab/Simulink and the ADVISOR software. What is more,based on the traditional automobile’s braking quality evaluating indicator and the characteristic of HEV, the evaluating indicator of HEV regenerative braking system quality is proposed,and choosing model brake operating mode and city drive cycle mode, the off-line simulation on the regenerative braking test bed is carried on.In that way,we can know the test bed is good or not.At last, the user operation window of HEV regenerative braking test bed is built using the LabVIEW software, and the convenient human-machine interaction operation on test bed is realized.It provides a good visualization operation contact window for later hardware in the loop simulation of test bed and the data processing of vehicle test.The research result is useful for building HEV regenerative braking test bed ,vehicle test and designing hybrid electric vehicle.更多还原
