动力传动一体化控制对提高车辆加速性能的研究

基于大功率柴油机和机械式自动变速器的动力传动一体化控制系统，是我国车辆行业的一个崭新课题。本文在介绍动力传动一体化控制系统组成及工作原理的基础上，重点讨论了一体化控制对提高车辆加速性能的影响。实车试验结果表明，与分立的柴油机电子控制系统和自动变速系统相比，动力传动一体化控制系统发挥了控制系统的优势，提高了车辆的加速性能。

A STUDY ON THE IMPROVEMENT OF VEHICLE''''S PERFORMANCE IN ACCELERATION THROUGH THE ADOPTION OF INTEGRATED POWERTRAIN CONTROL

Integrated powertrain control system based on large diesel engine and mechanical transmission is a new trend and subject in the development of vehicles in China. An introduction to its composition and principles of operation of the system is given. Emphasis of the paper is placed on a discussion of the effects of the integrated powertrain control on the vehicle's performance of acceleration. Proving ground tests show that, compared with the discrete engine electronic control unit and transmission electronic control unit, integrated powertrain control possesses its particular advantages in the control systems, and the vehicle's acceleration performance is much improved.
