Abstract

HIL(Hardware In Loop) test is a typical application of semi-physical simulation. It is an important function verification and test link in the development process of automotive electronic control systems. It has become a necessary means in the standardized development process, and it has been increasingly affected by various automotive OEMs(Original Equipment Manufacturer) and component manufacturers. Wide attention. This article focuses on the HIL test environment of the new energy vehicle TCU (Transmission Control Unit) control system, introduces the HIL test system architecture, software and hardware components, and the establishment process of the test environment. The test requirements are formulated according to the application scenarios of the TCU in the new energy vehicle, and the test requirements are based on the test requirements. Set up the HIL test environment. Considering that the motor speed regulation in practical applications is controlled by the vehicle controller, in order to more realistically simulate the vehicle use environment, this paper adopts the VCU(Vehicle Control Unit) and TCU dual-in-the-loop method for HIL testing, aiming at the functions of the electronic control unit controllers of the power system. Simulate the vehicle environment for testing and analyze the test results.
新能源汽车TCU HIL试验台研究*
硬件在环测试是半物理仿真的典型应用。它是汽车电子控制系统开发过程中重要的功能验证和测试环节。它已成为标准化发展过程中的必要手段,并日益受到各汽车oem(原始设备制造商)和零部件制造商的影响。广泛关注。本文以新能源汽车变速器控制单元(Transmission Control Unit, TCU)控制系统的HIL测试环境为重点,介绍了HIL测试系统的体系结构、软硬件组成,以及测试环境的建立过程。根据TCU在新能源汽车中的应用场景制定测试要求,以测试需求为基础制定测试要求。设置HIL测试环境。考虑到实际应用中的电机调速是由车载控制器控制的,为了更逼真地模拟车辆使用环境,本文针对电力系统电子控制单元控制器的功能,采用VCU(vehicle Control Unit)和TCU双在环的方法进行HIL测试。模拟车辆环境进行测试,并分析测试结果。
