Autonomous Vehicle (AV) research has focused on public acceptance of and intention to use AVs, with trust emerging as important to these variables. Research on AV trust has centered on trust in vehicle performance. However, trust evaluation may include AV manufacturers and developers, and regulation pertaining to AVs; thus, we expand our measurement of trust to include beliefs based on manufacturers and regulation. In this experiment, we manipulate information regarding manufacturer focus (i.e., an emphasis on standards, regulations, and research (SRR) versus speed to market) to determine its effect on trust. When information focused on SRR, we found higher levels of trust in AV performance and in manufacturers, compared to when it focused on speed to market. In addition, information regarding passenger control (i.e., the ability to take over for the vehicle and to determine privacy settings) was manipulated to yield either high or low passenger control conditions. Behavioral Intention (BI) to use AVs was lowest when speed to market was emphasized and when passenger control was low. Furthermore, trust was tested as a mediator between perceived risk and BI. Trust in AV performance partially mediated the relationship between perceived AV performance risk and BI. In addition, trust in AV regulation partially mediated the relationship between AV privacy/security risk and BI. Researchers should continue to examine trust beyond the AV itself to encompass trust in manufacturers and regulations. Those designing and marketing AVs should carefully consider decisions that influence manufacturer/developer reputation and passenger control due to their effect on intention to use AVs.

自动驾驶汽车 (AV) 研究的重点是公众对自动驾驶汽车的接受程度和使用意愿，信任对这些变量越来越重要。对 AV 信任的研究集中在对车辆性能的信任上。但是，信任评估可能包括 AV 制造商和开发商，以及与 AV 相关的法规；因此，我们扩大了对信任的衡量，以包括基于制造商和法规的信念。在此实验中，我们操纵有关制造商关注点的信息（即，对标准、法规和研究 (SRR) 的关注与上市速度）以确定其对信任的影响。与关注上市速度相比，当信息关注 SRR 时，我们发现对 AV 性能和制造商的信任度更高。此外，有关乘客控制的信息（即，接管车辆和确定隐私设置的能力）被操纵以产生高或低的乘客控制条件。当强调上市速度和乘客控制率较低时，使用 AV 的行为意图 (BI) 最低。此外，信任被测试为感知风险和商业智能之间的中介。对 AV 性能的信任在一定程度上调节了感知 AV 性能风险与 BI 之间的关系。此外，对 AV 监管的信任在一定程度上调节了 AV 隐私/安全风险与 BI 之间的关系。研究人员应继续检查 AV 本身以外的信任，以涵盖对制造商和法规的信任。
