摘　　要：HIL测试(硬件在环测试)是新能源车整车控制策略V流程开发中系统集成测试重要的验证方式。对整车控制器内部加速踏板信号处理模块进行集成测试,通过HIL上位机模拟加速踏板信号,测试整车控制器的响应时间、信号校验准确性及故障注入后整车控制器内部策略的安全保护机制。根据HIL测试后的问题反馈报告,策略工程师对其进行更改,以保证整车控制器在实车测试时的安全性和功能性的要求。HIL测试发生在整车控制器安装在实车测试前,利用虚拟闭环环境查找整车策略中的漏洞,能够有效降低在实车测试时的风险,节省测试时间,减少企业测试成本。It is very important for HIL （Hardware in loop） testing to verify the new energy vehicle V-flow control strategy in integration testing. The purpose of this paper is to test accelerating pedal mode with integration testing. HIL simulates accelerating pedal signal and tests the response time of controller, carries out the accuracy of signal calibration, the safety protection of the vehicle control strategy after FIU. It always feeds the test report back to strategy engineer after HIL testing and strategy engineer will solve the problem to ensure safety and function. When the controller is installed in the real vehicle, HIL testing can check vehicle control strategy, reduce the risk in the real vehicle testing, save test time and reduce test cost of enterprise.
