重型商用车性能测试系统开发与应用

Development and application of a performance test system for heavy duty commercial vehicles

针对目前车用性能测试系统体积庞大、功能单一、安全性和可靠性低等缺点,采用基于Matlab/Simulink平台的dSPACE开发环境,开发了以dSPACE实时仿真系统为核心的重型商用车性能测试系统,完成了测试系统布置,开发步骤设计,实现了整车性能试验数据的采集、处理、分析、显示以及保存。应用所开发的测试系统完成了重型商用车性能道路试验,获得了经验驾驶员的操纵数据和原型车的动力性指标,为AMT系统的研制开发奠定了基础。

To address limitations of vehicle performance testing systems such as huge size, single functions, low degrees of accuracy, and low stability a performance test system for heavy duty vehicle is developed using the dSPACE development environment based on Matlab/Simulink. Test system layout and development steps are designed. Vehicle performance testing data are acquired, displayed and saved. Based on this testing system, a heavy duty commercial vehicle performance road test is conducted, and operating data regarding experienced drivers and dynamic indices are obtained. The research results provide a theoretical basis for AMT development.
