Abstract

The present invention improves the accuracy of predicting rarely occurring behavior of moving bodies, without reducing the accuracy of predicting commonly occurring behavior of moving bodies. A vehicleis provided with a moving body behavior prediction device. The moving body behavior prediction deviceis provided with a first behavior prediction unitand a second behavior prediction unit. The first behavior prediction unitlearns first predicted behaviorso as to minimize the error between behavior prediction results for moving bodies and behavior recognition results for the moving bodies after a prediction time has elapsed. The second behavior prediction unitlearns future second predicted behaviorof the moving bodies around the vehicleso that the vehicledoes not drive in an unsafe manner.
