US Patent 9428196 Vehicle driving behavior predicting device

A vehicle driving behavior predicting device that predicts a driving behavior of a vehicle at a prediction target point based on speed information or acceleration information of the vehicle includes: a storage unit storing a reference template indicating a transition of the speed information or the acceleration information corresponding to the driving behavior being a prediction target in a predetermined prediction section to the prediction target point; a converting unit converting the reference template to a converted template indicating a transition of a speed or acceleration from an entry speed to a case in which the driving behavior being the prediction target is exhibited based on the entry speed of the vehicle into the prediction section; and a predicting unit predicting the driving behavior at the prediction target point by comparing the converted template with a current transition of the speed information or the acceleration information.
