| description | The invention discloses a vehicle driving state safety assessment method based on a perceptual risk field in a network connection environment, and belongs to the technical field of vehicle intelligent interaction and traffic safety. Vehicle motion state information in a network connection area is collected through a cloud, and historical motion state and real-time motion state data of each vehicle are obtained; the historical motion state data of the vehicle is analyzed and processed to obtain the driving style parameters of the driver, including the expected time headway and the driver aggressive degree; constructing a perceptual risk field model by combining the driving style parameters of the driver and the real-time motion state data of the vehicle; and calculating the field intensity of the perceptual risk field through the perceptual risk field model, calculating the driving safety factor of the vehicle according to the driving scene of the vehicle, and finally obtaining a vehicle driving state safety e |
