摘要: 为提升高速公路汽车自适应巡航时的燃油经济性,建立了一种经济型巡航车速规划模型. 根据汽车巡航时的道路条件及气候环境参数等信息,规划汽车的经济型巡航车速. 首先构筑试验环境进行遍历试验,建立汽车百公里燃油消耗量数据库; 然后采用云模型相关理论建立运行车速和行驶阻力与燃油消耗量之间的映射关系,预测出不同行驶阻力条件下的经济车速; 最后根据这些经济车速规划出经济型巡航速度的变化轨迹. 经试验验证,按照经济型巡航速度变化轨迹行驶的燃油消耗比自动巡航状态下的明显降低,提高了汽车的燃油经济性.

Abstract:

In order to improve the fuel economy of expressway running vehicles in adaptive cruise state,a speed planning model of vehicles in economical cruise is established.The model plans vehicle's economical cruising speed according to road conditions and climate environment parameters,First of all a test environment is constructed to perform a traverse test,and a database of fuel consumption per hundred kilometers is established.Then,in order to predict the economical speed under different driving resistances,the mapping relationship between running speed as well as running resistance and fuel consumption is revealed based on the related theory of cloud model.Finally,the speed change trajectory in economical cruise state is planned according to the economical vehicle speed.Test results show that the fuel consumption of the vehicle along the economical cruising speed change trajectory reduces significantly and fuel economy is effectively improved.

Key words: vehicle cruise, fuel economy, cloud model, vehicle speed planning
