联合仿真模型的汽车网关自动化测试系统设计

Design of Automated Test System for Vehicle Gateway Combined with Simulation Model

针对现有手动汽车网关模块测试效率低的问题,设计了一种联合Simulation Model的自动化网关测试系统。该系统通过定制的测试配置盒配置测试环境,通过CANoe建模语言CAPL编写测试脚本,联合CAPL编写整车仿真模型程序,实现对网关模块的自动化测试。与手动测试对比,该自动化测试系统可最大限度地还原实车状态,测试内容更全面,测试效率更高,无关信号丢帧率为0%。

In order to improve test efficiency of the existing manual vehicle gateway module,an automated gateway test system combined with Simulation Model was designed.This system configures testing environment through customized test configuration kit,uses CANoe modeling language CAPL to write testing script,and combines with CAPL to write vehicle simulation model program,to achieve automated test of gateway module.Compared with the manual test,test content of the automated test system is more comprehensive and the testing efficiency is higher,frame loss rate of extraneous signal is 0 percent.
