HEV控制器硬件在环仿真平台接口电路设计
 摘要：硬件在环仿真作为一种实验手段，具有缩短研发周期，重复性好，节约成本等优点，目前已广泛应用并成为HEV控制器开发的主要手段。将已有的整车模型载入dSPACE中，同时采用实物的电子负载和可编程电源模拟电动机模型，构成硬件在环仿真平台，实现对HEV整车控制器的性能和控制策略的检测。本课题所做的接口电路目的是实现dSPACE与电子负载和可编程电源之间的通讯控制。主要以MC9S12DB128BCPV型MCU为核心，构建周围接口电路，包括A/D转换和D/A转换，CAN通讯，SCI通讯，开关量的输入输出等，最终设计的电路有一定的抗干扰性和稳定性，能够很好的检测控制器的性能和控制策略。

Abstract: As a means of experiment ，hardware in the loop simulation has many advantages, such as decreasing development time，saving money and well repeatability. At present, it has become a primary means of developing HEV controllers. Loading the existed vehicle models into the dSPACE board, while using physical electronic load and programmable power to simulation motor model, that constitutes the hardware in the loop simulation platform, and realize the testing of the performance and control strategy of the HEV. The aim of the interface circuit we did is to achieve the communication and control between the programmable power, the dSPACE board and the electronic load. Using the MC9S12DB128BCPV as core to build the around interface circuit which include the D / A converter, CAN and SCI Communications, digital input and output, etc. the circuit we design is reasonable and anti-interference. So it can meet the need.
