摘　　要：在介绍快速原型仿真原理及dSPACE系统的基础上,设计了通用性较高的车辆底盘集成控制器开发平台。硬件部分是由单板系统MicroAutoBox作为控制器和Rapidpro通用模块用于信号调理与功率驱动组成,执行机构为EPS无刷直流电机和SAS步进电机。利用simulink/stateflow软件建立数字调节器模型,通过RTI模块用图形化方式对所有I/O接口进行设置,实现与dSPACE的通讯,RTW将所建模型自动生成C语言代码编译器下载。实车试验结果表明,运用该方法可快速得到满足控制需求的硬件电路以及控制软件代码,在达到较为理想控制效果的基础上能显著缩短控制器的开发周期、降低开发成本。Based on the introduction of the principle of the hardware-in-the-loop simulation and dSPACE system,the paper describes the design of the wider vehicle chassis integrated with controllers developing platform.On one hand,the hardware is composed of a single board system MicroAutoBox as controller and Rapidpro universal module for signal conditioning and power drive,while the actuator is made up of EPS DC motor with brushless and SAS stepper motor.On the other hand,the software employed Simulink/stateflow to build digital regulator model,and then set all I/O interface with a graphical way by the RTI module to communication with dSPACE,finally the model created will automatically generate complier of C codes to download.The vehicle testing shows that employing this method can rapidly meet the need of controlling and software codes to achieve ideal control effect,shortening the developing cycle of controller and reducing the cost of developing.
