Collision warning system plays a key role in the prevention of driving distractions and drowsy driving. Previous studies have proven the advantages of tactile warnings in reducing driver's brake response time. At the same time, tactile warnings have been proved effective in take-over request (TOR) for partially autonomous vehicles. How the performance of tactile warnings can be optimized is an ongoing hot research topic in this field. Thus, the presented low-cost driving simulation software and methods are introduced to attract more researchers to take part in the investigation. The presented protocol has been divided into five sections: 1) participants, 2) driving simulation software configuration, 3) driving simulator preparation, 4) vibrating toolkit configuration and preparation, and 5) conducting the experiment. In the exemplar study, participants wore the tactile vibrating toolkit and performed an established car-following task using the customized driving simulation software. The front vehicle braked intermittently, and vibrating warnings were delivered whenever the front vehicle was braking. Participants were instructed to respond as quickly as possible to the sudden brakes of the front vehicle. Driving dynamics, such as the brake response time and brake response rate, were recorded by the simulation software for data analysis. The presented protocol offers insight into the exploration of the effectiveness of tactile warnings on different body locations. In addition to the car-following task that is demonstrated in the exemplar experiment, this protocol also provides options to apply other paradigms to the driving simulation studies by making simple software configuration without any code development. However, it is important to note that due to its affordable price, the driving simulation software and hardware introduced here may not be able to fully compete with other high-fidelity commercial driving simulators. Nevertheless, this protocol can act as an affordable and user-friendly alternative to the general high-fidelity commercial driving simulators.
碰撞预警系统在预防驾驶分心和疲劳驾驶方面发挥着关键作用。先前的研究已经证明了触觉警告在缩短驾驶员制动反应时间方面的优势。同时，触觉警告在部分自动驾驶车辆的接管请求（TOR）中也被证明是有效的。如何优化触觉警告的性能是该领域当前的热门研究课题。因此，本文介绍了低成本的驾驶模拟软件和方法，以吸引更多研究人员参与调查。所提出的方案分为五个部分：1）参与者，2）驾驶模拟软件配置，3）驾驶模拟器准备，4）振动工具包配置和准备，以及5）进行实验。在示例研究中，参与者佩戴触觉振动工具包，并使用定制的驾驶模拟软件执行既定的跟车任务。前车间歇性制动，每当前车制动时都会发出振动警告。参与者被要求对前车的突然制动尽快做出反应。驾驶动力学，如制动反应时间和制动反应率，由模拟软件记录下来用于数据分析。所提出的方案为探索触觉警告在不同身体部位的有效性提供了见解。除了示例实验中展示的跟车任务外，该方案还提供了通过简单的软件配置而无需任何代码开发就可将其他范式应用于驾驶模拟研究的选项。然而，需要注意的是，由于其价格实惠，这里介绍的驾驶模拟软件和硬件可能无法与其他高保真商业驾驶模拟器充分竞争。尽管如此，该方案可以作为一般高保真商业驾驶模拟器的一种经济实惠且用户友好的替代方案。
