摘　　要：电控系统的控制精度很大程度上取决于标定数据的准确度,改进标定优化方法一直是各大公司努力的方向。本文简述了电控系统自动标定优化的基本思想和方法,以及当前的最新发展趋势,并对各种方法进行了分析,并以自行开发的自动标定系统说明了自动标定系统的构成,最后阐明了我国汽油机电控系统标定技术的发展方向。The accuracy of electronically controlled engine system depends on the calibrated parameters to a large extent, many large companies have been trying to improve the parameter calibration and optimize methods. The article introduces the principles of the various methods, the latest development of the parameter calibration, and optimizes and analyzes the methods, and provides an example of automatic-calibration system designed by ourselves. Finally the direction for engine calibration in our country is assesed.

关 键 词：汽油机 电控系统 标定试验 优化方法
