Research on Smart Start-Stop System of Engine

介绍了整车姿态角定义、测量方法和校验标准,通过实例分析整车姿态出现较大偏差时的原因分析思路及控制方法,并列举出影响整车姿态的几大关键因素,指出整车姿态设计时需重点关注的事项。

The purpose is to better study the structure of the engine Smart Start-Stop system and its control strategy, to make it more adaptable to application of the road conditions in China. At the same time of saving energy and reducing emissions,it can avoid frequent shutdown and restart of the engine. This paper mainly uses the ME7 system as an example to illustrate the structure of the intelligent start-stop,analyzes its working principle,and focuses on the control strategy and control system of the intelligent system. Finally, the conclusion is put forward that the condition of the attachment should be added to the control logic of the intelligent start-stop system when the vehicle is in traffic jam. This paper has some practical reference value.
