The user’s perspective on highly automated driving systems is mostly studied during first contact/single usage. However, with repeated usage, acceptance and usage of automated driving systems might change. For advanced driving assistance systems, change with growing system usage is studied as behavioural adaptation. This concept of behavioural adaptation is applied to highly automated driving systems. In a driving simulator study, N = 61 drivers used an automated driving system for motorways during six experimental sessions. The drivers were free to activate / deactivate the function as they liked and to spend driving time on self-chosen side tasks. Automation level was varied as a between-subject factor (L3 vs. L4). Results show a more positive evaluation of the L4 system and behavioural adaptation for both levels over the course of the six sessions. For most aspects, behavioural adaptation is independent of system level (e.g., for system evaluation, distribution of attention). Only for drivers’ reaction to requests to intervene, a strong impact of system level on the occurrence behavioural adaption can be found. The results are discussed with regard to the theory of behavioural adaptation.

用户对高度自动驾驶系统的看法主要在第一次接触/单次使用期间进行研究。然而，随着重复使用，自动驾驶系统的接受和使用可能会发生变化。对于高级驾驶辅助系统，随着系统使用量的增加而发生的变化被研究为行为适应。这种行为适应的概念适用于高度自动化的驾驶系统。在驾驶模拟器研究中，N = 61 名司机在六个实验阶段使用高速公路自动驾驶系统。驾驶员可以根据自己的喜好自由激活/停用该功能，并将驾驶时间花在自己选择的副业上。自动化水平作为受试者之间的因素（L3 与 L4）而变化。结果显示，在六节课的过程中，两个级别的 L4 系统和行为适应都得到了更积极的评价。对于大多数方面，行为适应与系统级别无关（例如，对于系统评估、注意力分布）。仅针对驾驶员对干预请求的反应，可以发现系统水平对发生行为适应的强烈影响。就行为适应理论对结果进行了讨论。
