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.
