1、 前言

汽发动机电子控制系统 (EECS) 是通过对发动机点火、喷油、空气与燃油的比率、排放废气等进行电子控制,使发动机在最佳工况状态下工作,以达到提高其整车性能、节约能源、降低废气排放的目的。汽车市场发展的焦点是围绕安全、节能、环保、舒适、方便的主题为消费者提供高质量、安全可靠、多功能低价位的创新产品。开发商面临的挑战是快速研发这类产品,在最短的时间内将新产品推向市场。汽车电子技术的发展为提高整车性能起到了关键性的作用。随着汽车电子化发展的深入,32 位微控制器将逐渐取代 8 位、16 位微控制器而成为主流应用产品。

2、 方案概述

Ameya360 汽车引擎控制系统解决方案发动机控制系统由传感器、控制器、执行器三大部分组成。传感器是感知信息的部件,可向控制器提供汽车运行状况和发动机工况等相关信息。发动机控制器即发动机控制模块 (ECM),可以接收来自传感器的信息并存储相关信息,经计算和分析处理后发出相应的控制指令给执行器。执行器即执行元件,其作用是执行控制器的指令,从而达到控制目标。
