摘要
A reconstruction method for a secure environment envelope of a smart vehicle based on the driving behavior of a vehicle in front, starting from the simulation of the behavior of a real driver pre-estimating the potential collision risk of the drive area in front, introducing a prediction regarding the driving behavior of the vehicle in front to the environment sensing link of the smart vehicle, reconstructing, on the basis of the prediction result regarding the driving behavior of the vehicle in front, a secure environment envelope of the smart vehicle. The method uses a signal as an observed value, such as the trajectory point sequence of the vehicle in front, the indicators of the vehicle in front, the smart vehicle speed, the relative longitudinal speed of the smart vehicle and the vehicle in front, etc., and predicts the driving behavior of the vehicle in front by means of a hidden markov model (HMM); the method corrects, on the basis of the prediction result about the driving behavior of the vehicle in front, the transverse spacing and the longitudinal spacing between the smart vehicle and the vehicle in front, realizes the reconstruction of a secure environment envelope of a smart vehicle, and further realizes the pre-estimation regarding the potential collision risk of the smart vehicle in the safe drive area, and improves the security of the smart vehicle.
