A driving support method by a controller for supporting driving of a host-vehicle in a traveling scene in which a host-vehicle track (30, 30a, 30b) that is a track on which the host-vehicle travels and a first other vehicle track (31, 31a, 31b, 31c) that is a track on which a first other vehicle (21, 21a, 21b, 21c) travels intersect with each other at an intersecting point (P, P1, P2, P3) and a second other vehicle (22, 22a, 22b, 22c) that is different from the first other vehicle (21, 21a, 21b, 21c) arrives at a point faster than the first other vehicle (21, 21a, 21b, 21c), the point being a point on the first other vehicle track (31, 31a, 31b, 31c) until the first other vehicle (21, 21a, 21b, 21c) arrives at the intersecting point (P, P1, P2, P3) and being a point at which the first other vehicle track (31, 31a, 31b, 31c) and a second other vehicle track that is a track on which the second other vehicle (22, 22a, 22b, 22c) travels intersect with each other; the driving support method characterized in that the controller: estimates a shielding time (Tab) that is a time during which the second other vehicle (22, 22a, 22b, 22c) shields the first other vehicle track (31, 31a, 31b, 31c) to the intersecting point (P, P1, P2, P3) by estimating a vehicle speed of the second other vehicle (22, 22a, 22b, 22c) at the time of shielding the first other vehicle track and estimating a time during which the second other vehicle (22, 22a, 22b, 22c) and the first other vehicle track (31, 31a, 31b, 31c) overlap with each other or a time during which the second other vehicle (22, 22a, 22b, 22c) and a first lane area (41, 41a, 41b) that is an area that includes the first other vehicle track (31, 31a, 31b, 31c) and also includes the lane width overlap with each other; estimates a required entry time (Tp) that is a time from when the host-vehicle starts entering the intersecting point (P, P1, P2, P3) to when the host-vehicle finishes entering the intersecting point (P, P1, P2, P3) by estimating a time from when at least a portion of the host-vehicle starts overlapping with the first other vehicle track (31, 31a, 31b, 31c) to a time when a position of the host-vehicle overlaps with the first other vehicle track (31, 31a, 31b, 31c); compares the shielding time (Tab) with the required entry time (Tp); and determines that the host-vehicle can enter the intersecting point (P, P1, P2, P3) in a case where the shielding time (Tab) is longer than the required entry time (Tp). estimates a shielding time (Tab) that is a time during which the second other vehicle (22, 22a, 22b, 22c) shields the first other vehicle track (31, 31a, 31b, 31c) to the intersecting point (P, P1, P2, P3) by estimating a vehicle speed of the second other vehicle (22, 22a, 22b, 22c) at the time of shielding the first other vehicle track and estimating a time during which the second other vehicle (22, 22a, 22b, 22c) and the first other vehicle track (31, 31a, 31b, 31c) overlap with each other or a time during which the second other vehicle (22, 22a, 22b, 22c) and a first lane area (41, 41a, 41b) that is an area that includes the first other vehicle track (31, 31a, 31b, 31c) and also includes the lane width overlap with each other; estimates a required entry time (Tp) that is a time from when the host-vehicle starts entering the intersecting point (P, P1, P2, P3) to when the host-vehicle finishes entering the intersecting point (P, P1, P2, P3) by estimating a time from when at least a portion of the host-vehicle starts overlapping with the first other vehicle track (31, 31a, 31b, 31c) to a time when a position of the host-vehicle overlaps with the first other vehicle track (31, 31a, 31b, 31c); compares the shielding time (Tab) with the required entry time (Tp); and determines that the host-vehicle can enter the intersecting point (P, P1, P2, P3) in a case where the shielding time (Tab) is longer than the required entry time (Tp).
