汽车智能启停系统的控制算法研究

Study of Control Algorithm for Vehicle Smart Start-Stop System

介绍了汽车启停系统的应用背景和基本原理,分析了启停系统的主要控制算法,提出了一种基于逻辑门限值的启停系统控制算法。该控制算法通过采集车辆运行状态信号判断车辆是否具有智能启停条件,通过采集驾驶员操作信号判断是否进行智能启停。研究表明,该控制算法能够控制开启或关闭怠速停机及怠速启动功能,并在需要的时候进行怠速停机或怠速启动,实现智能启停功能。

The study introduces the applications and basic principles of the vehicle smart start-stop system and it also analyzes the start-stop system control algorithm and proposed a start-stop system control algorithm based on the logic threshold method. This control algorithm determines whether a vehicle has the smart start-stop condition by collecting the vehicle operating condition signal and determines whether the start-stop action is needed by collecting the driver＇s operation signal. The study shows that the control algorithm can successthlly control the turning on or off of the idle stop and start function, and can stop or start the engine when it is needed. Therefore, the smart start-stop function can be achieved.
