Many new in-vehicle systems focus on accident prevention by facilitating the driving task. One such driving aid is an in-vehicle collision avoidance warning system (IVCAWS), used to alert the driver to an impending collision. Our study evaluated the effects of an imperfect IVCAWS both on driver headway maintenance and on driver behavior in response to warning system errors. Our results showed that drivers tend to overestimate their headway and consequently drive with short and potentially dangerous headways, and that IVCAWSs are a useful tool for educating drivers to estimate headway more accurately. Moreover, our study showed that after a relatively short exposure to the system, drivers were able to maintain longer and safer headways for at least six months. The practical implications of these results are that the use of an IVCAWS should be considered for inclusion in driver education and training programs.
许多新型车载系统通过辅助驾驶任务来专注于事故预防。一种这样的驾驶辅助设备是车载碰撞避免警告系统（IVCAWS），用于提醒驾驶员即将发生的碰撞。我们的研究评估了不完善的IVCAWS对驾驶员车间距保持以及对驾驶员针对警告系统错误的行为的影响。我们的结果表明，驾驶员往往高估自己的车间距，因此以短且可能危险的车间距驾驶，并且IVCAWS是一种用于教育驾驶员更准确地估计车间距的有用工具。此外，我们的研究表明，在相对较短时间接触该系统后，驾驶员能够在至少六个月内保持更长且更安全的车间距。这些结果的实际意义在于，应考虑将IVCAWS的使用纳入驾驶员教育和培训计划。
