Research on improving driver's situational awareness in automatic driving by vibration information

This paper explores the ways to improve driver's awareness in the case of automatic driving. The first study uses the experimental method to study whether there is a significant difference in the improvement of situational awareness of drivers when they are distracted by performing secondary tasks through voice and vibration. The results show that the driver's situational awareness score of transmitting environmental information through vibration is significantly higher than that of sound; the second experimental took the content of information transmitted as a variable to study whether there was a significant difference in the improvement of drivers' situational awareness when vibration transmitted different information. The results of this study explore a method to combine the application of vibration information with the demand for automatic driving. By comparing the vibration information and voice information, this study found that it is feasible to transmit the hazards in the environmental information to the driver through vibration. Compared with voice information, it can significantly improve the driver's situational awareness and help the driver to establish an understanding of the surrounding environment So as to improve the quality of taking over and promote driving safety.
