摘要
研究汽车嵌入式发动机的节能控制问题,由于汽车在启动过程中,发动机燃烧不充分,会造成电动机的启动电流过大,并且包含高噪声,使得汽车的动态非必要能耗增加。传统的限流限压调节算法的频率固定,很难做到真正的动态调节,不能适应非线性的大规模变化。为提高节能效果,提出了一种嵌入式动态能耗平衡的汽车节能调度算法。根据动态平衡相关理论,获取汽车运行过程中发动机的动态能耗关系,并为汽车发动机节能调度提供准确的数据。仿真结果表明,建立多核嵌入式汽车发动机任务调度模型,克服了传统算法中频率固定的弊端,说明改进算法能够有效降低汽车调度过程中的能源消耗。
Research of automotive embedded engine energy saving control problem. This paper proposed an auto- mobile energy saving scheduling algorithm based on embedded dynamic balance energy consumption, According to the related theory of dynamic balance, the operation process of the engine＇s dynamic energy consumption relationship was obtained to provide accurate data for automobile engine energy - efficient scheduling. The multiple nuclear em- bedded automobile engine task scheduling model was established so as to realize the energy saving control of automobile engines. The experimental results show that this algorithm can effectively reduee the car scheduling process energy consumption.
