摘要
为了缩短汽车防抱死制动控制系统的开发测试时间,提出了硬件在回路仿真平台的ABS测试方法,在研究车辆动力学模型的基础上,设计了基于FPGA的片上仿真器;结合片上仿真器,提出了电磁阀特性模型,制动系统模型和基于片上仿真器的仿真方法;基于片上仿真器,开发了具有自主知识产权的硬件在回路仿真测试平台,模拟汽车的运行情况,为电控单元(ECU)提供一个模拟的车辆运行的环境,减少实际装车实验的成本;企业试用表明该平台独立于车辆物理系统,适用于多种车型。在此平台上对ABS进行了仿真测试和控制参数匹配,试验证明,该仿真平台可缩短ABS的开发时间。
The hardware in loop test approach was proposed. The dynamic model of vehicle was studied ; the simulator on chip （SOC） based on FPGA was designed. The characteristic model of electromagnetic valve, the model of tire and the simulation technique based on SOC were put forward. Based on SOC, the hardware in loop simulation platform was developed to simulate the status of vehicle. It provided the electronic control unit with simulated environment, so as to reduce the cost of experiment. After tryout, it was shown that the platform was independent with the real system of vehicle, suitable for many kinds of vehicles. The ABS system was tested and the control parameters were calibrated on this platform. The experimental results show the platform can reduce ABS development time.
