Abstract

The present invention relates to the technical field of vehicle safety. Disclosed are a self-diagnosis method and device for a vehicle occupant protection system. According to the present invention, the real vehicle control parameters are input into an AEB digital twin model, and a virtual second vehicle motion response parameter and a virtual second AEB system response parameter are calculated; the correlation between a real first vehicle motion response parameter and the virtual second vehicle motion response parameter of a vehicle is calculated, and the correlation between a real first AEB system response parameter and the virtual second AEB system response parameter of the vehicle is calculated; and on the basis of the correlations between the real response parameters and the virtual response parameters, it is determined whether an AEB system is abnormal or not. The self-diagnosis function of the AEB system based on digital twin technology is achieved.
