DRIVING ASSISTANCE METHOD AND DRIVING ASSISTANCE DEVICE

A driving assistance method includes: detecting (S4) a first other vehicle (v1) entering an intersection on a first route (21) where a host vehicle (20) is traveling from a second route (21) different from the first route (21); predicting (S7) whether or not the first other vehicle (v1) will stop in the intersection, and predicting a stop position of the first other vehicle (v1) when the first other vehicle (v1) is predicted to stop in the intersection; calculating (S8) a minimum distance (d1) of a first gap between a vehicle body of the first other vehicle (v1) and a surrounding object around the first other vehicle (v1) or between the vehicle body of the first other vehicle (v1) and a road edge of a travel lane of the first other vehicle (v1) when the first other vehicle (v1) stops at the predicted stop position; and predicting (S9, S12, S18) according to the calculated minimum distance (d1) whether or not a second other vehicle (v2), which is a following vehicle behind the first other vehicle (v1), may slip through the first gap from behind the first other vehicle (v1).
