汽车经济性巡航控制策略研究

Research on Automobile Economic Cruise Control Strategy

为了达到节能减排的目的,提高当前汽车巡航的准确性及安全性,提出基于发动机万有特性的经济巡航方案。首先获得车辆位置信息及所受阻力,然后借助建立的行驶阻力与经济车速的关系数据库得到巡航经济车速。最后,利用Matlab验证了所设计的巡航方案油耗量显著降低。

In order to achieve the purpose of energy saving and emission reduction,improve the accuracy and safety of the current car cruising,and put forward an economic cruising scheme based on the engine characteristics.Firstly,the vehicle location information and resistance are obtained,and then the cruising economic speed is obtained by using the established database of the relationship between driving resistance and economic speed.Finally,Matlab was used to verify that the fuel consumption of the cruise scheme was significantly reduced.
