Levels one to three of driving automation systems (DAS) are spreading fast. However, as the DAS function become more and more sophisticated, not only the driver's driving skills will be reduced, but also the problem of over-trust will become serious. If a driver has over-trust in the DAS, he/she will become not aware of hazards in time. To prevent the driver's over-trust in the DAS, this paper discusses the followings: 1) the definition of over-trust in the DAS; 2) a hypothesis of occurrence condition and occurrence process of over-trust in the DAS, and 3) a driving behavior model based on the trust in the DAS, the risk homeostasis theory and the over-trust prevention human-machine interface (HMI).
