LEARNING METHOD AND LEARNING DEVICE FOR DETERMINING WHETHER TO SWITCH MODE OF VEHICLE FROM MANUAL DRIVING MODE TO AUTONOMOUS DRIVING MODE BY PERFORMING TRAJECTORY-BASED BEHAVIOR ANALYSIS ON RECENT DRIVING ROUTE

摘要

A learning method for calculating collision probability, to be used for determining whether it is appropriate or not to switch driving modes of a vehicle capable of an autonomous driving, by analyzing a recent driving route of a driver is provided. And the method includes steps of: (a) a learning device, on condition that a status vector and a trajectory vector are acquired, performing processes of (i) instructing a status network to generate a status feature map and (ii) instructing a trajectory network to generate a trajectory feature map; (b) the learning device instructing a safety network to calculate a predicted collision probability representing a predicted probability of an accident occurrence; and (c) the learning device instructing a loss layer to generate a loss by referring to the predicted collision probability and a GT collision probability, which have been acquired beforehand, to learn at least part of parameters.
