摘要
提出一种兼顾节能与安全的电动车自适应巡航控制算法。定量分析加速度对电动车经济性的影响,构建燃油经济性与跟车安全性的性能指标,采用模型预测控制方法协同优化系统性能指标,仿真与试验的结果表明,所提出的算法能兼顾整车经济性与安全性。
An adaptive cruise control algorithm is proposed for electric vehicles to coordinate both its economy and safety. The effects of acceleration on the economy of electric vehicles are quantitatively analyzed and the performance indicators for both fuel economy and tracking safety are established. Model predictive control technique is adopted to conduct coordinated optimization on the performance indicators of the system. The results of both simulations and tests indicate that the algorithm proposed can effectively coordinate both economy and safety of electric vehicles.
