自动化所带来的好处经常被用来促进自动化的采用。然而，目前尚不清楚解释是否促进了对自动驾驶汽车（AV）的接受。在这项研究中，我们在驾驶模拟器中进行了一项有32名参与者的受试者内实验，使用四种不同的条件。这四个条件包括：（1）没有解释，（2）在AV动作之前或（3）之后给出的解释，以及（4）驾驶员在听到解释之后批准或不批准AV的动作的选项。我们研究了四个AV结果：信任，偏好AV，焦虑和精神负荷。结果表明，解释之前提供的AV行为与更高的信任和偏好的AV，但没有显着差异的焦虑和工作量。这些结果对自动驾驶汽车的采用具有重要意义。
Explanations given by automation are often used to promote automation adoption. However, it remains unclear whether explanations promote acceptance of automated vehicles (AVs). In this study, we conducted a within-subject experiment in a driving simulator with 32 participants, using four different conditions. The four conditions included: (1) no explanation, (2) explanation given before or (3) after the AV acted and (4) the option for the driver to approve or disapprove the AV's action after hearing the explanation. We examined four AV outcomes: trust, preference for AV, anxiety and mental workload. Results suggest that explanations provided before an AV acted were associated with higher trust in and preference for the AV, but there was no difference in anxiety and workload. These results have important implications for the adoption of AVs.
