Fan and water pump in traditional cooling system are controlled by engine directly and this fixed control pattern restricts flexibility of engine in different working status specially in execrable working status overheat of cooling system resulting in engine abnormality ; in order to change this condition , electromotion of cooling fan has been studied prophasely , further more good effect is acquired . on the base of it , the paper expatiates on the research on intelligent control of cooling water pump
传统冷却系统的风扇和水泵皆由发动机直接控制，固定的控制模式限制了发动机在不同工况下的适应性，尤其是在恶劣的工况下冷却系统过热导致的发动机异常；为改变这种状况，冷却风扇的电动控制已经进行了前期研究，而且取得了良好的效果，在此基础上，本文又对冷却水泵智能控制的研究进行了详细地阐述。
