电动车增程器控制单元的硬件在环仿真系统设计

Design of the hardware-in-the-loop simulation system for the range-extender's ECU of electric vehicles

基于增程器的工作原理,并结合增程器控制单元的开发要求,采用了MATLAB/xPC Target的实时仿真环境构架,分别从硬件在环仿真(HILS)系统的硬件和软件两个方面对增程器控制单元的硬件在环仿真系统进行设计与开发。整个平台包括基础平台、信号接口系统、模拟负载系统和监控软件等部分。开发的HILS系统应用于增程器控制单元的设计开发和功能测试,缩短了增程器控制单元的开发周期。

Based on the work principle of range-extenders,the hardware and the software of the system were designed and developed to meet the design requirement of the control unit of range-extenders by using the real-time simulation structure of MATLAB/xPC Target.The HILS system included basic bench,signal interface system,load device and monitoring software.The developed HILS system can be used to test the function and to assist the development of the control unit of extended range devices with short term.
