汽车发动机电子控制单元的软件开发

为了提高实时响应，控制准确性，ECU 的网络性能和稳定性 ，新的发动机电子控制软件开发是基于闭环控制系统和一些基本的参数计算公式。

发动机电子控制系统的基础上的32位微控制器命名为MPC5634M的软件程序设计，模块化和层次化的编程方法。该程序执行基本功能的传感器信号的采集，计算喷射和点火，致动器驱动，等.

本文将介绍软件架构，和基于32位MCU新的特性和功能基础上的控制逻辑的相关内容。-Software Development of Automotive Engine Electronic Control Unit

To improve real-time response, control accuracy, network performance and stability of ECU, a new engine ctronic control　software is developed based on closed-loop control system and some

basic parameter computational formulas.



A software program for engine electronic control system based on

a 32-bit microcontroller named MPC5634M is designed in modular and



hierarchical programming method. The program performs the basic functions of sensor signals gathering, lculation of injection　and ignition, actuators driving, etc.

This article will introduce related content about software architecture, control logic based on new functions and characteristics of 32-bit MCU.
