Abstract: Abstract: With the continuous advancement of science and technology, new technologies have been constantly ushered into people’s lives, and the autonomous driving technology has also been developing rapidly. However, the technological development alone cannot increase people’s acceptance. In order to improve the acceptance of unmanned driving technology, the automation acceptance model was studied. Explorations were conducted on how to combine the acceptance model with interaction design, and analyses were made regarding the user experience of external vehicle interaction based on the acceptance model. Through the analysis of the use scenarios of external vehicle interaction in semi-closed scenes and the user journey map during pedestrians’ interaction with automation vehicles, a pedestrian behavior characteristic model was summarized. In addition, on the basis of related research on the automation acceptance model, the effectiveness and acceptance of external vehicle interaction were improved from the perspective of trust and compatibility. Based on the AAM model, a strategyfitting the pedestrian behavior characteristics and cognition was proposed for human-machine external vehicle interaction, thereby enhancing communication efficiency and acceptance.
