Ethical decision-making in autonomous vehicles has been a significant area of research since the emergence of the Trolley Problem. However, current studies fail to effectively incorporate the operative state of the vehicle and instead rely exclusively on sociological attributes for decision-making. This paper establishes three ethical traffic scenarios that reflect the most typical ethical dilemmas. Based on this, we examine the ethical decision-making of autonomous vehicles in each scenario. Firstly, to enable the decision-making system of autonomous vehicles to solve ethical dilemmas, a coupled ethical reward function model is innovatively proposed based on human feedback that integrates knowledge from sociology, economics, and vehicle dynamics. Furthermore, an ethics-driven multi-modal network model is proposed to extract morphological features and dynamic features from perceptual information and road test data, respectively. Finally, an ethical simulation experiment is conducted, which demonstrates that the decision-making strategies generated by the proposed model in the ethical traffic scenario are more aligned with human intentions compared to those of the control group.
