基于PSO的节能ACC策略

Energy Saving ACC Control Strategy Based on PSO

针对传统ACC算法对车辆行驶经济性考虑不足的问题,提出了基于PSO算法的节能ACC策略。在巡航模式中引入滑行巡航模型,并以油耗为目标,采用PSO算法进行滑行巡航加速度优化。以CarSim车辆模型为基础,建立了节能ACC策略模型,并通过CarSim与Simulink进行联合仿真。结果表明:相同的行驶距离情况下,节能ACC策略相对于常规ACC定速巡航策略油耗更低。

Aiming at the problem that vehicle driving economy were not fully taken into consideration by traditional ACC control algorithm,energy-saving ACC control strategy based on particle swarm optimization(PSO)was proposed.In the cruise mode,the taxi cruise model was introduced.With the goal of reducing fuel consumption,the taxi cruise was optimized in acceleration by PSO algorithm.The energysaving ACC strategy model was built based on CarSim vehicle model,and co-simulation was carried out by CarSim and Simulink.The results show that within the same driving distance,the energy-saving ACC strategy consumes less fuel than the conventional ACC cruise strategy.
