基于驾驶模拟器的HMI可用性测试实验环境研究

Experiment Research on HMI Usability Test Environment Based on Driving Simulator

针对现有汽车驾驶模拟器的功能局限,探讨了对于测试汽车人机界面(HMI),如何搭建一个可用性测试实验环境,探究出汽车HMI在驾驶模拟器上的可用性测试方法.针对汽车的智能化和网联化功能,设计并搭建出基于智能驾驶座舱的台架,实现了通用智能汽车驾驶仿真,使汽车HMI设计测试过程明细化,继而验证设计的可行性和有效性.以先进驾驶辅助系统中的LDW(车道偏离预警)功能为例,分析了LDW的应用场景,最后将HMI设计应用到驾驶模拟器上进行可用性测试,以期对未来HMI测试方法产生一定的启发.

In view of the limitation of the existing vehicle simulators,the problems were analyzed in this paper,including the usability test environment for the test of automobile human machine interface(HMI),the usability test methods of the automobile HMI on a driving simulator.Taking advantage of the current development of the intelligent and network-linked function of the car,a car bench on a smart cockpit was designed and built to achieve the general intelligent vehicle driving simulation,so as to make the HMI testing process more refined,and verify the feasibility and validity of the design method.And then,the LDW(lane departure warning)function of the advanced driving assistance system was set as an example to analyze the application scenario of LDW.Finally,the HMI design was applied to a driving simulator for usability testing,intending to bring some inspiration to the future HMI test methods.
